    Seasonal Forecasts, Climatic Change and Human Health : Health and Climate (2008)
    Springer
    Details
    Keywords: Assessment ; Malaria ; Public Health ; Scale ; Weather ; climate change ; public health policy ; temperature
    Description / Table of Contents: Awareness that many key aspects of public health are strongly influenced by climate is growing dramatically, driven by new research and experience and fears of climate change and the research needed to underpin policy developments in area is growing rapidly . This awareness has yet to translate into a practical use of climate knowledge by health policy-makers. Evidence based policy and practice is the mantra of the health sector. If climate scientists are to contribute effectively to health policy at local and global scales then careful empirical studies must be undertaken – focused on the needs of the public health policy and decision-makers. Results presented at the Wengen conference make clear that the science and art of integrating climate knowledge into the control of climate sensitive diseases on a year to year time frame as well as careful assessments of the potential impacts of climate change on health outcomes over longer time frames is advancing rapidly on many fronts. This includes advances in the empirical understanding of mechanisms, methodologies for modeling future impacts, new partnership developments between the health and climate community along with access to relevant data resources, and education and training. In a rapidly evolving field this book provides a snapshot of these emerging themes.

    Springer
    Details
    Keywords: Air ; Chlor ; GSM-Postponed Project ; Manual ; Oxide ; Water ; bacteria ; microorganism ; pollution ; production ; soil ; toxicity
    Description / Table of Contents: Environmental Chemistry: Fundamentals, by Jorge Ibanez et al., is an exceptionally useful and well organized book. After reviewing basic chemical concepts, Environmental Chemistry: Fundamentals quickly progresses to more advanced and contemporary applications including ozone depletion, physiochemical and biological treatment of pollutants, and green chemistry. The chemistry of processes of the atmosphere, lithosphere and hydrosphere are covered in detail and the effects of pollutants on each of these chemical processes are extensively considered, as are their effects on the biosphere. The book also has an experimental companion, Environmental Chemistry: Microscale Laboratory Experiments, which includes an array of environmental chemistry experiments that can be readily performed at the microscale level. Ideas for additional open-ended projects are provided for all experiments, and they impart a thorough introduction to environmental experimentation. I strongly recommend Environmental Chemistry: Fundamentals and its experimental accompaniment, Environmental Chemistry: Microscale Laboratory Experiments. Dr. Zvi Szafran Vice President for Academic Affairs and Professor of Chemistry Southern Polytechnic State University Our Earth is a remarkable reaction vessel. It is of paramount importance that students grow in their understanding and awareness of the astounding effects that chemistry and biochemistry have on our environment…and why they are so significant to our present and future hopes as a civilization. Environmental Chemistry: Microscale Laboratory Experiments, intended to complement lessons in the companion textbook Environmental Chemistry: Fundamentals, covers the chemical and biochemical processes that take place in air, water, soil, and living systems. The corresponding experiments range from the characterization of aqueous media to pollutant-treatment schemes. For increased safety, as well as for reduced costs, wastes, and environmental damage, the experiments are presented at the microscale level. Pre- and post-laboratory exercises and open-ended projects accompany each experiment, to develop problem-solving skills and initiative among students.

    Characterization of volcanic thermal anomalies by means of sub-pixel temperature distribution analysis (2005)
    Springer
    Details
    Publication Date: 2020-11-23
    Description: Abstract: The simultaneous solution of the Planck equation (involving the widely used “dual-band” technique) using two shortwave infrared (SWIR) bands allows for an estimate of the fractional area of the hottest part of an active lava flow (fh), and the background temperature of the cooler crust (Tc). The use of a high spectral and spatial resolution imaging spectrometer with a wide dynamic range of 15 bits (DAIS 7915) in the wavelength range from 0.501 to 12.67 µm resulted in the identification of crustal temperature and fractional areas for an intra-crater hot spot at Mount Etna, Italy. This study indicates the existence of a relationship between these Tc and fh extracted from DAIS and Landsat TM data. When the dual band equation system is performed on a lava flow, a logarithmic distribution is obtained from a plot of the fractional area of the hottest temperature versus the temperature of the cooler crust. An entirely different distribution is obtained over active degassing vents, where increases in Tc occur without any increase in fh. This result indicates that we can use scatter plots of Tc vs. fh to discriminate between different types of volcanic activity, in this case between degassing vents and lava flows, using satellite thermal data.

    Thermal characterization of the Vulcano fumarole field (2008)
    Springer
    Details
    Publication Date: 2020-11-17
    Description: Ground-based thermal infrared surveys can contribute to complete heat budget inventories for fumarole fields. However, variations in atmospheric conditions, plume condensation and mixed-pixel effects can complicate vent area and temperature measurements. Analysis of vent temperature frequency distributions can be used, however, to characterise and quantify thermal regions within a field. We examine this using four thermal infrared thermometer and thermal image surveys of the Vulcano Fossa fumarole field (Italy) during June 2004 and July 2005. These surveys show that regions occupied by low temperature vents are characterised by distributions that are tightly clustered around the mean (i.e., the standard deviation is low), highly peaked (positive kurtosis) and skewed in the low temperature direction (negative skewness). This population is associated with wet fumaroles, where boiling controls maximum temperature to cause a narrow distribution with a mode at 90–100°C. In contrast, high temperature vent regions have distributions that are widely spread about the mean (i.e., the standard deviation is high), relatively flat (negative kurtosis) and skewed in the high temperature direction (positive skewness). In this dry case, fumaroles are water-free so that maximum temperatures are not fixed by boiling. As a result greater temperature variation is possible. We use these results to define two vent types at Vulcano on the basis of their thermal characteristics: (1) concentrated (localized) regions of high temperature vents, and (2) dispersed low temperature vents. These occur within a much larger region of diffuse heat emission across which surfaces are heated by steam condensation, the heat from which causes elevated surface temperatures. For Vulcano's lower fumarole zone, high and low temperature vents occupied total areas of 3 and 6 m2, respectively, and occurred within a larger (430 m2) vent-free zone of diffuse heat emission. For this lower zone, we estimate that 21– 43×103 W of heat was lost by diffuse heat emission. A further 4.5×103 W was lost by radiation from high temperature vents, and 6.5×103 W from low temperature vents. Thus, radiative heat losses from high and low temperature vents within Vulcano's lower fumarole zone respectively account for 10% and 15% of the total heat lost from this zone. This shows that radiation from open vents can account for a non-trivial portion of the total fumarole field heat budget.

    Crustal seismic velocity in the Marche region (Central Italy): computation of a minimum 1-D model with seismic station corrections. (2008)
    Springer
    Details
    Publication Date: 2020-11-16
    Description: A 1-D velocity model for the Marche region (central Italy) was computed by inverting P- and S-wave arrival times of local earthquakes. A total of 160 seismic events with a minimum of ten observations, a travel time residual ≤ 0.8 s and an azimuthal gap lower than 180° have been selected. This “minimum 1-D velocity model” is complemented by station corrections, which can be used to take into account possible near-surface velocity heterogeneities beneath each station. Using this new P-wave velocity model and the program HYPOELLIPSE (Lahr, 1999), the selected local events were relocated. Earthquake locations in this study are of higher quality with respect to the original ones. The obtained minimum 1-D velocity model can be used to improve the routine earthquakes locations and represents a further step towards more detailed seismotectonic studies of the area.

    Synthetic ANaB(NaxLi1 ¡ xMg1)CMg5Si8O22(OH)2 (with x = 0.6, 0.2 and 0) P21/m amphiboles at high pressure: a synchrotron infrared study (2008)
    Springer
    Details
    Publication Date: 2020-11-17
    Description: high-pressure behavior of three synthetic amphiboles crystallized with space group P21/m at room conditions in the system Li2O–Na2O–MgO–SiO2–H2O has been studied by in situ synchrotron infrared absorption spectroscopy. The amphiboles have compositions ANa B(NaxLi1 ¡ xMg1) CMg5 Si8 O22(OH)2 with x = 0.6, 0.2 and 0.0, respectively. The high-P experiments up to 32 GPa were carried out on the U2A beamline at Brookhaven National Laboratory (NY, USA) using a diamond anvil cell under non-hydrostatic or quasi-hydrostatic conditions. The two most intense absorption bands in the OH-stretching infrared spectra can be assigned to two non-equivalent O–H dipoles in the P21/m structure, bonded to the same local environment M1M3Mg3–OH–ANa, and pointing toward two diVerently kinked tetrahedral rings. In all samples these bands progressively merge to give a unique symmetrical absorption with increasing pressure, suggesting a change in symmetry from P21/m to C2/m. The pressure at which the transition occurs appears to be linearly correlated to the aggregate B-site dimension. The infrared spectra collected for amphibole B(Na0.2Li0.8Mg1) in the frequency range 50 to 1,400 cm¡1 also show a series of changes with increasing pressure. The data reported here support the inference of Iezzi et al. (Am Miner 91:479–482, 2006a) regarding a new high-pressure C2/m amphibole polymorph characterized by two equivalent and kinked double-chains, stable at very high-pressure.

    The earthquake of 6 September 2002 and the seismic history of Palermo (Northern Sicily, Italy): Implications for the seismic hazard assessment of the city (2005)
    Springer
    Details
    Publication Date: 2021-03-01
    Description: On September 6, 2002, aML =5.6 earthquake, occurring some tens of kilometres offshore from the Northern Sicilian coast (Southern Tyrrhenian Sea), slightly damaged the city of Palermo and surroundings (degree 6 in the European Macroseismic Scale 1998). The macroseismic investigation of the shock and a detailed study of effects of the main earthquakes which affected Palermo in the past have been performed in order to evaluate the seismic response of the city. Moreover, the comparison of the recent event, which is instrumentally constrained, with historical earthquakes allows us to infer new insights on the seismogenic sources of the area, that seem located offshore in the Tyrrhenian sea. In the last 500 years, Palermo has never been completely destroyed but has suffered effects estimated between intensities 6 and 8 EMS-98 many times (1693, 1726, 1751, 1823, 1940, 1968, 2002). The damage scenarios of the analysed events have shown that damage distribution is strongly conditioned by soil response in the different parts of the city and by a high building vulnerability, mainly in the historical centre and in the south-eastern zone of the modern city. As a matter of fact, Palermo has always suffered greater effects than those reported for other nearby localities. The hazard assessment obtained using observed site intensities has shown that the probability of occurrence for intensity 8 (the strongest intensity observed in Palermo) exceeds 99% for 550 years, while the estimated mean return period is 152 ± 40 years. These results, in connection with building vulnerability due to the urban expansion before the introduction of seismic code, suggest that the city is exposed to a relatively high seismic risk.

    Comparison of Integrated Geodetic Data Models and Satellite Radar Interferograms to Infer Magma Storage During the 19911993 Mt. Etna Eruption (2005)
    Springer
    Details
    Publication Date: 2017-04-03
    Description: We compare the results obtained from the modelling of EDM, GPS, levelling and tilt data measured in the first part of the 19911993 eruption at Etna to the InSAR data acquired during the second part. The geodetic changes are very marked in the first half of the eruption and constrain a deflation source located at a few kilometers of depth ( 3 km b.s.l.), in agreement with other independent geophysical evidence. SAR data, available during the second part of the eruption, were analysed for different time intervals in the second part of the eruption. The interpretation of SAR interferograms reveals a large-scale but less marked deflation of the volcano that could be caused by a deeper source. This second source is in accord with a second deeper anomaly revealed by recent seismic investigations. The combination of geodetic data modelling and SAR images suggests a complex plumbing system composed at least of two possible storage regions located at different depths.

    Types of eruptions of Etna volcano AD 16702003: implications for short-term eruptive behaviour (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Analysis of the historical records of Etnas eruptive activity for the past three centuries shows that, after the large 1669 eruption, a period of about 60 years of low-level activity followed. Starting from 1727, explosive activity (strombolian, lava fountaining and subplinian) at the summit crater increased exponentially to the present day. Since 1763, the frequency of flank eruptions also increased and this value remained high until 1960; afterward it further increased sharply. In fact, the number of summit and flank eruptions between 1961 and 2003 was four times greater than that of the pre-1960 period. This long-term trend of escalating activity rules out a pattern of cyclic behaviour of the volcano. We propose instead that the 16702003 period most likely characterises a single eruptive cycle which began after the large 1669 eruption and which is still continuing. On the basis of the eruptive style, two distinct types of flank eruptions are recognised: Class A and Class B. Class A eruptions are mostly effusive with associated weak strombolian activity; Class B eruptions are characterised by effusive activity accompanied by intense, long-lasting, strombolian and lava fountaining activity that produces copious tephra fallouts, as during the 2001 and 20022003 eruptions. Over the past three centuries, seven Class B eruptions have taken place with vents located mainly on the south-eastern flank, indicating that this sector of the volcano is a preferential zone for the intrusion of volatile-rich magma rising from the deeper region of the Etna plumbing system.

    Changes in eruptive style during the A.D. 1538 Monte Nuovo eruption (Phlegrean Fields, Italy): the role of syn-eruptive crystallization (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: The Monte Nuovo eruption is the most recent event that occurred at Phlegrean Fields (Italy) and lasted from 29 September to 6 October 1538. It was characterized by 2 days of quasi-sustained phreatomagmatic activity generating pumice-bearing pyroclastic density currents and forming a 130-m-high tuff cone (Lower Member deposits). The activity resumed after a pause of 2 days with two discrete Vulcanian explosions that emplaced radially distributed, scoria-bearing pyroclastic flows (Upper Member deposits). The juvenile products of Lower and Upper Members are, respectively, phenocryst-poor, light-coloured pumice and dark scoria fragments with K-phonolitic bulk compositions, identical in terms of both major and trace elements. Groundmass is formed by variable proportions of K-feldspar and glass, along with minor sodalite and Fe-Ti oxide present in the most crystallized samples. Investigations of groundmass compositions and textures were performed to assess the mechanisms of magma ascent, degassing and fragmentation along the conduit and implications for the eruptive dynamics. In pumice of the Lower Member groundmass crystal content increases from 13 to 28 vol% from the base to the top of the sequence. Products of the Upper Member consist of clasts with a groundmass crystal content between 30 and 40 vol% and of totally crystallized fragments. Crystal size distributions of groundmass feldspars shift from a single population at the base of the Lower Member to a double population in the remaining part of the sequence. The average size of both populations regularly increases from the Lower to the Upper Member. Crystal number density increases by two orders of magnitude from the Lower to the Upper Member, suggesting that nucleation dominated during the second phase of the eruption. The overall morphological, compositional and textural data suggest that the juvenile components of the Monte Nuovo eruption are likely to record variations of the magma properties within the conduit. The different textures of pumice clasts from the Lower Member possibly reflect horizontal gradients of the physical properties (P, T) of the ascending magma column, while scoriae from the second phase are thought to result from the disruption of a slowly rising plug crystallizing in response to degassing. In particular, crystal size distribution data point to syn-eruptive degassing-induced crystallization as responsible for the transition in eruptive style from the first to the second phase of the eruption. This mechanism not only has been proved to profoundly affect the dynamics of dome-forming calc-alkaline eruptions, but may also have a strong influence in driving the eruption dynamics of alkaline magmas of intermediate to evolved compositions.

    Intrusive Mechanisms at Mt. Etna Forerunning the July-August 2001 Eruption from Seismic and Ground Deformation Data (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: In this work we present seismological and ground deformation evidence for the phase preparing the July 18 to August 9, 2001 flank eruption at Etna. The analysis performed, through data from the permanent seismic and ground deformation networks, highlighted a strong relationship between seismic strain release at depth and surface deformation. This joint analysis provided strong constraints on the magma rising mechanisms. We show that in the last ten years, after the 1991–1993 eruption, an overall accumulation of tension has affected the volcano. Then we investigate the months preceding the 2001 eruption. In particular, we analyse the strong seismic swarm on April 20–24, 2001, comprising more than 200 events (Mmax = 3.6) with prevalent dextral shear fault mechanisms in the western flank. The swarm showed a ca. NE-SW earthquake alignment which, in agreement with previous cases, can be interpreted as the response of the medium to an intrusive process along the approximately NNW-SSE volcano-genetic trend. These mechanisms, leading to the July 18 to August 9, 2001 flank eruption, are analogous to ones observed some months before the 1991–1993 flank eruption and, more recently, in January 1998 before the February-November 1999 summit eruption.

    Observations of Electromagnetic Radiation in the Central Apennines Seismic Region (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: In recent years, continuous radio-noise recording is in use at many geophysical observatories, in order to detect possible earthquake precursors and/or coseismic signals. The recordings obtained indicate that electromagnetic radiation (e.g., in the range of 10-40 kH) can indeed be treated as seismic precursor. We present here the examples of successful prediction observation, which we have obtained in the Central Apennines region at the l'Aquila Observatory (Polish-Italian cooperation). A short discussion on relation between the evolution of stresses (dislocation dynamics) and electromagnetic emission supplements this paper.

    Survey on fluoride, bromide and chloride contents in public drinking water supplies in Sicily (Italy) (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Six hundred and sixty-seven water samples were collected from public drinking water supplies in Sicily and analysed for electric conductivity and for their Cl-, Br- and F- contents. The samples were, as far as possible, collected evenly over the entire territory with an average sampling density of about one sample for every 7600 inhabitants. The contents of Cl- and Br-, ranging between 5.53 and 1302 mg/l and between 〈 0.025 and 4.76 mg/l respectively, correlated well with the electric conductivity, a parameter used as a proxy for water salinity. The highest values were found both along the NW and SE coasts, which we attributed to seawater contamination, and in the central part of Sicily, which we attributed to evaporitic rock dissolution. The fluoride concentrations ranged from 0.023 to 3.28 mg/l, while the highest values (only 3 exceeding the maximum admissible concentration of 1.5 mg/l) generally correlated either with the presence in the area of crystalline (volcanic or metamorphic) or evaporitic rocks or with contamination from hydrothermal activity. Apart from these limited cases of exceeding F- levels, the waters of public drinking water supplies in Sicily can be considered safe for human consumption for the analysed parameters. Some limited concern could arise from the intake of bromide-rich waters (about 3% exceeding 1 mg/l) because of the potential formation of dangerous disinfection by-products.

    From COST 238 To COST 296: Four European COST Actions On Ionospheric Physics And Radio Propagation (2008)
    American Institute of Physics
    Details
    Publication Date: 2017-04-04
    Description: COST (Co-operation in the field of Scientific and Technical Research) is an important instrument supporting co-operation among scientists and researchers across Europe now joining 35 member countries. Scientific projects in the COST framework are called COST Actions and have the objectives embodied in their respective Memorandum of Understanding (MoU). The main objectives of the COST Actions within the European ionospheric and radio propagation community have been: to study the influence of upper atmospheric conditions on terrestrial and Earthspace communications, to develop methods and techniques to improve existing and generate new ionospheric and propagation models over Europe for telecommunication and navigation applications and to transfer the results to the appropriate national and international organizations, institutions and industry dealing with the modern communication systems. This paper summarises in brief the background and historical context of four ionospheric COST Actions and outlines their main objectives and results. In addition, the paper discusses the dissemination of the results and the collaboration among the participating institutions and researchers.

    On the suitability of 1 s geophone for ambient noise measurements in the 0.1–20Hz frequency range: experimental outcomes (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Following the ongoing debate about suitability of short-period sensor for seismic noise measurements at frequencies lower than 1Hz, in this study we compare recordings from two different seismometers (Güralp CMG-3ESPC and Mark L4C-3D) installed side by side in the GeoForschungsZentrum laboratory. The comparison carried out in terms of Power Spectral Density and coherency analysis shows an excellent agreement between the shortperiod and the broad-band recordings in the frequency band 0.2–20 Hz. Therefore, this result highlights that with a calibrated short-period sensor one can obtain the same results that would be obtained by using a broad-band seismometer in the band of engineering interest.

    A Glimpse into the Seismicity of the Ionian Islands between 1658 and 1664 (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Mostly based on traditional catalogues, without further research, several modern parametric catalogues are nevertheless straightforward, without question marks, and easily misleading (chronology, epicentre, epicentral intensity, not to speak of magnitude). The example of an Ionian time-window (1658-1664), with several major events, shows that the historical seismicity of the Ionian Islands, often thought to be well-known, actually needs a more or less drastic revision. A wealth of sources was collected, mostly from the Archives of the Republic of Venice, then ruling the main three islands of the Ionian Archipelago; it was ascertained that there are no important chronological gaps in the surviving documentation. Similarly outstanding, and in fact at the basis of a more balanced and precise view of one of the events in this time-window, are the souvenirs of Christoff von Degenfeld, a German nobleman at the service of the Republic of Venice. His manuscript, discovered at the library of Karlsruhe (Germany) in 1992, has been consulted again in the original, on the occasion of the preparation of this paper. Some question marks remain on the distributions of macroseismic effects of the earthquakes within this time-window, and this is due to the lack of information concerning the mainland. For this reason this study does not propose epicentres and, of course, magnitudes. An unusually long documentary appendix is provided, with the hope that it might contribute in discouraging authors of parametric earthquake catalogues from hasty exploitation and interpretation of often unreliable current catalogues.

    The fidelity of melt inclusions as records of melt composition (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: A series of experiments created melt inclusions in plagioclase and pyroxene crystals grown from a basaltic melt at 1,150 C, 1.0 GPa to investigate diffusive fractionation during melt inclusion formation; additionally, P diffusion in a basaltic melt was measured at 1.0 GPa. Melt inclusions and melts within a few 100 microns of plagioclase– melt interfaces were analyzed for comparison with melt compositions far from the crystals. Melt inclusions and melt compositions in the boundary layer close to the crystal–melt interface were similar, but both differ significantly in incompatible element concentrations from melt found greater than approximately 200 microns away from the crystals. The compositional profiles of S, Cl, P, Fe, and Al in the boundary layers were successfully reproduced by a two-step model of rapid crystal growth followed by diffusive relaxation toward equilibrium after termination of crystal growth. Applying this model to investigate possible incompatible element enrichment in natural melt inclusions demonstrated that at growth rates high enough to create the conditions for melt inclusion formation, *10-9–10-8 m s-1, the concentration of water in the boundary layer near the crystal was similar to that of the bulk melt because of its high diffusion coefficient, but sulfur, with a diffusivity similar to major elements and CO2, was somewhat enriched in the boundary layer melt, and phosphorus, with its low diffusion coefficient similar to other high-field strength elements and rare earth elements, was significantly enriched. Thus, the concentrations of sulfur and phosphorus in melt inclusions may over-estimate their values in the bulk melt, and other elements with similar diffusion coefficients may also be enriched in melt inclusions relative to the bulk melt.

    A syn-eruptive ground deformation episode measured by GPS, during the 2001 eruption on the upper southern flank of Mt Etna (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Ground deformation occurring on the southern flank of Mt Etna volcano during the JulyAugust 2001 eruption was monitored by GPS measurements along an EW profile crossing the fissure system. This profile was measured eight times during the eruption, using the 'stop and go' semi-kinematic technique. Horizontal and vertical displacements between GPS surveys are reported for each station. The most significant event is a deformation episode occurring during the first week of the eruption, between 2527 July. Displacements were measured on benchmarks close to the eruptive fissure and the tensile 1989 fracture. Data inversions for measured displacements were performed using the Okada model. The model shows the narrowing of the 2001 dyke accompanied by a dextral dislocation along an east-dipping fault, parallel to the 1989 fracture.

    A multi-disciplinary study of the 200203 Etna eruption: insights into a complex plumbing system (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: The 200203 Mt Etna flank eruption began on 26 October 2002 and finished on 28 January 2003, after three months of continuous explosive activity and discontinuous lava flow output. The eruption involved the opening of eruptive fissures on the NE and S flanks of the volcano, with lava flow output and fire fountaining until 5 November. After this date, the eruption continued exclusively on the S flank, with continuous explosive activity and lava flows active between 13 November and 28 January 2003. Multi-disciplinary data collected during the eruption (petrology, analyses of ash components, gas geochemistry, field surveys, thermal mapping and structural surveys) allowed us to analyse the dynamics of the eruption. The eruption was triggered either by (i) accumulation and eventual ascent of magma from depth or (ii) depressurisation of the edifice due to spreading of the eastern flank of the volcano. The extraordinary explosivity makes the 200203 eruption a unique event in the last 300 years, comparable only with La Montagnola 1763 and the 2001 Lower Vents eruptions. A notable feature of the eruption was also the simultaneous effusion of lavas with different composition and emplacement features. Magma erupted from the NE fissure represented the partially degassed magma fraction normally residing within the central conduits and the shallow plumbing system. The magma that erupted from the S fissure was the relatively undegassed, volatile-rich, buoyant fraction which drained the deep feeding system, bypassing the central conduits. This is typical of most Etnean eccentric eruptions. We believe that there is a high probability that Mount Etna has entered a new eruptive phase, with magma being supplied to a deep reservoir independent from the central conduit, that could periodically produce sufficient overpressure to propagate a dyke to the surface and generate further flank eruptions.

    Description: It has been argued that the dominant period T_p derived from the initial seconds of a seismogram, hence only depending on the initial phases of earthquake rupture, seems to scale with the final size of the earthquake. We provide a physical interpretation for the observed scaling and explain how the final earthquake size could be controlled by the initial phase of rupture.

    Effusive Activity at Mount Etna Volcano (Italy) During the 20th Century: A Contribution to Volcanic Hazard Assessment (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Mount Etna is an open conduit volcano, characterised by persistent activity, consisting of degassing and explosive phenomena at summit craters, frequent flank eruptions, and more rarely, eccentric eruptions. All eruption typologies can give rise to lava flows, which represent the greatest hazard by the volcano to the inhabited areas. Historical documents and scientific papers related to the 20th century effusive activity have been examined in detail, and volcanological parameters have been compiled in a database. The cumulative curve of emitted lava volume highlights the presence of two main eruptive periods: (a) the 1900–1971 interval, characterised by a moderate slope of the curve, amounting to 436 · 106 m3 of lava with average effusion rate of 0.2 m3/s and (b) the 1971–1999 period, in which a significant increase in eruption frequency is associated with a large issued lava volume (767 · 106 m3) and a higher effusion rate (0.8 m3/s). The collected data have been plotted to highlight different eruptive behaviour as a function of eruptive periods and summit vs. flank eruptions. The latter have been further subdivided into two categories: eruptions characterised by high effusion rates and short duration, and eruptions dominated by low effusion rate, long duration and larger volume of erupted lava. Circular zones around the summit area have been drawn for summit eruptions based on the maximum lava flow length; flank eruptions have been considered by taking into account the eruptive fracture elevation and combining them with lava flow lengths of 4 and 6 km. This work highlights that the greatest lava flow hazard at Etna is on the south and east sectors of the volcano. This should be properly considered in future land-use planning by local authorities.

    Geochemistry and potential use of groundwater in the Rocca Busambra area (Sicily, Italy) (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: In the Rocca Busambra area (mid-west Sicily, Italy), from November 1999 to July 2002, 23 water points including wells and springs were sampled and studied for their chemical and isotopic compositions. Two rain gauges were also installed at different altitudes, and rainwater was collected monthly to determine the isotopic composition. The obtained results revealed the Rocca Busambra carbonate complex as being the main recharge area on account of its high permeability value. From a chemical view point, two main groups of water can be distinguished: calcium– magnesium–bicarbonate-type and calcium–magnesium– chloride–sulphate-type waters. The first group reflects the dissolution of the carbonate rocks; the second group probably originates from circulation within flyschoid sediments. Three water wells differ from the other samples due to their relatively high Na and K content, which probably is to be referred to a marked interaction with the ‘‘Calcareniti di Corleone’’ formation, which is rich in glauconite [(K, Na)(Fe3+, Al, Mg)2(Si, Al)4O10(OH)2]. In accordance with WHO guidelines for drinking water (2004), almost all the samples collected can be considered drinkable, with the exception of four of them, whose NO3 -, F- and Na+ contents exceed the limits. On the contrary, the sampled groundwater studied is basically suitable for irrigation

    Impact of extreme CO2 levels on tropical climate: A CGCM study (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: A coupled general circulation model has been used to perform a set of experiments with high CO2 concentration (2, 4, 16 times the present day mean value). The experiments have been analyzed to study the response of the climate system to strong radiative forcing in terms of the processes involved in the adjustment at the ocean-atmosphere interface. The analysis of the experiments revealed a non-linear response of the mean state of the atmosphere and ocean to the increase in the carbon dioxide concentration. In the 16xCO2 experiment the equilibrium at the ocean-atmosphere interface is characterized by an atmosphere with a shut off of the convective precipitation in the tropical Pacific sector, associated with air warmer than the ocean below. A cloud feedback mechanism is found to be involved in the increased stability of the troposphere. In this more stable condition the mean total precipitation is mainly due to large-scale moisture flux even in the tropics. In the equatorial Pacific Ocean the zonal temperature gradient of both surface and sub-surface waters is significantly smaller in the 16xCO2 experiment than in the control experiment. The thermocline slope and the zonal wind stress decrease as well. When the CO2 concentration increases by about two and four times with respect to the control experiment there is an intensification of El Nino. On the other hand, in the experiment with 16 times the present-day value of CO2, the Tropical Pacific variability weakens, suggesting the possibility of the establishment of permanent warm conditions that look like the peak of El Nino.

    Jean Vogt 1929-2005. His Life as a Seismologist, Geologist, Geographer, and Historian (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Jean Vogt was born in 1929 in Strasbourg (France), where he attended primary and secondary school. At the University of Strasbourg, he graduated in Geography, and majored in Geomorphology. His professor was the geographer Jean Tricart, who taught him the importance of both geological field work and archive investigation. In 1955 he joined the French West-Africa Geological Service and later the French Bureau for Geology and Mines (BRGM). Along the following 20 years he lived as a “geological” globetrotter in a number of countries, dispensing his time between the field and the archives. In these years, he was concerned mainly with mining geology, geomorphology, superficial deposits, and landslides. This unique experience led him in 1975 to the responsibility of the “Seismo-Tectonic Project”, the BRGM project in relation with the French nuclear power programme. From 1975 to 1984, he gave a substantial impulse to the study of French historical earthquakes, and since then he visited almost every public archive in France, and several major archives and libraries in Europe and abroad. He took care at the same time of the follow-up of macroseismic studies of present-day earthquakes. After he retired in 1984, he continued on a personal basis his investigations of historical earthquakes, in Europe, the Middle East, North Africa, and the Caribbean area. Alongside and for about 50 years, Jean Vogt investigated uninterruptedly the agrarian history of Northeastern France and Southwestern Germany. He published in scientific journals and in local learned societies bulletins more than 500 notes and articles devoted to a variety of subjects, such as soil erosion, agriculture, cattle trade, and social conflicts. Jean Vogt died on 5 June 2005 in Strasbourg. His scientific legacy consists of a wealth of published papers, manuscripts, documentation related to history and seismology, awaiting to be further exploited, as he would have done.

    Strong Earthquakes in North-Western Africa in the Second Half of the 17th Century, AD: A Critical Reappraisal of the Historical Evidence (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: The recent seismological literature recorded three strong earthquakes in Algeria, Libya and Tunisia between 1656 and 1694 AD. The historical evidence for these derives from European sources only (gazettes, journalistic pamphlets, missionary literature). Considering the kind of sources involved, their likely biases and the geographical distances that divided their places of production from the places that they spoke about, it is possible that some of these accounts could be less than reliable, and therefore have little use as materials from which to assess earthquake parameters. To answer these doubts, we have retrieved, cross-checked and critically analysed the original historical sources quoted in previous compilations and studies.

    Macroseismic Intensity Modelling of Earthquakes in Southern Spain: Attenuation and Tectonic Implications (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: A modelling of the observed macroseismic intensity of historical and instrumental earthquakes in southern Spain is proposed, with the aim of determining the macroseismic parameters for seismic hazard evaluation in a region in which the characterization of intensity distribution of seismic events shows different levels of difficulty referable to the complex faults system of the area in study. The adopted procedure allows an analytical determination of epicenters and principal attenuation directions of earthquakes with a double level of verification with reference to the maximum shaking area and structural lineaments of the region, respectively. The analyses, carried out on a suitable number of events, highlight, therefore, some elements for a preliminary characterization of a seismic zonation on the basis of the consistency between seismic intensity distribution of earthquakes and corresponding structural framework.

    The role of the Pernicana Fault System in the spreading of Mt. Etna (Italy) during the 2002-2003 eruption (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Flank instability and collapse are observed at many volcanoes. Among these, Mt. Etna is characterized by the spreading of its eastern and southern flanks. The eastern spreading area is bordered to the north by the EW-trending Pernicana Fault System (PFS). During the 20022003 Etna eruption, ground fracturing along the PFS migrated eastward from the NE Rift, to as far as the 18 km distant coastline. The deformation consisted of dextral en-echelon segments, with sinistral and normal kinematics. Both of these components of displacement were one order of magnitude larger (~1 m) in the western, previously known, portion of the PFS with respect to the newly surveyed (~9 km long) eastern section (~0.1 m). This eastern section is located along a pre-existing, but previously unknown, fault, where displaced man-made structures give overall slip rates (11.9 cm/year), only slightly lower than those calculated for the western portion (1.42.3 cm/year). After an initial rapid motion during the first days of the 20022003 eruption, movement of the western portion of the PFS decreased dramatically, while parts of the eastern portion continued to move. These data suggest a model of spreading of the eastern flank of Etna along the PFS, characterized by eruptions along the NE Rift, instantaneous, short-lived, meter-scale displacements along the western PFS and more long-lived centimeter-scale displacements along the eastern PFS. The surface deformation then migrated southwards, reactivating, one after the other, the NNWSSE-trending Timpe and Trecastagni faults, with displacements of ~0.1 and ~0.04 m, respectively. These structures, along with the PFS, mark the boundaries of two adjacent blocks, moving at different times and rates. The new extent of the PFS and previous activity over its full length indicate that the sliding eastern flank extends well below the Ionian Sea. The clustering of seismic activity above 4 km b.s.l. during the eruption suggests a deep décollement for the moving mass. The collected data thus suggests a significant movement (volume 〉1,100 km3) of the eastern flank of Etna, both on-shore and off-shore.

    Role of conduit shear on ascent of the crystal-rich magma feeding the 800-year-b.p. Plinian eruption of Quilotoa Volcano (Ecuador) (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: We have characterized pumice products belonging to the climactic phase of the 800-year-b.p. Quilotoa eruption. Bulk rock compositions, petrography, mineral, and glass chemistry and textural investigations were performed on the three end-member pumice types, namely white, gray, and mingled pumices. All the investigated pumice clasts are dacites characterized by the same bulk rock composition and mineralogical assemblage, but glass compositions and bulk textures change according to different pumice types. White pumice has higher crystallinity (~48 wt%), abundant euhedral pheno/microphenocrysts, no groundmass microlites, the most evolved glass compositions (7478 wt% SiO2), and heterogeneous vesicle populations marked by deformed and highly coalesced vesicles with thin walls. Gray pumice exhibits lower crystallinity (2936 wt%), abundant broken and/or resorbed crystals, ubiquitous groundmass phenocryst fragments and microlites, the widest range of glass compositions (6978 wt% SiO2), and quite homogeneous poorly deformed and coalesced vesicles with thicker walls. Mingled pumices are characterized by the alternation of bands or patches with white and gray pumice compositional and textural characteristics. We attribute heterogeneities in glass compositions and crystal and vesicle textures to processes occurring within volcanic conduits as magma is ascending to the surface. In particular, the above observations and results are consistent with an origin of a gray magma by heating of the original white magma in a strongly sheared region of the conduit because of a mechanism of viscous dissipation and crystal grinding and resorption at the conduit walls. The less viscous gray magma, therefore, would enable the onset and preservation of a high mass flux of the eruption otherwise difficult to explain for highly viscous crystal-rich dacitic magmas.

    On the Observed Intensity Filtering in the Anisotropic Distribution Modelling of Macroseismic Intensity (2005)
    Springer

    Publication Date: 2017-04-04
    Description: The anisotropic modelling of intensity distribution, affected by the construction of macroseismic planes, allows an analysis of the influence of each point of observed intensity on the analytical determination of epicenter and of the principal attenuation directions. Such a procedure is a vital aid in the cases in which the observed intensity points, that, for location or joined intensity level, are not consistent with an anisotropic model of intensity attenuation. A suitable filtering on intensity levels associated with the points of the intensity map, for a better modelling of observed intensity distribution, is proposed with the aim of a better seismic hazard evaluation

    The occurrence of Mt Barca flank eruption in the evolution of the NW periphery of Etna volcano (Italy) (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Geological surveys, tephrostratigraphic study, and 40Ar/39Ar age determinations have allowed us to chronologically constrain the geological evolution of the lower NW flank of Etna volcano and to reconstruct the eruptive style of the Mt Barca flank eruption. This peripheral sector of the Mt Etna edifice, corresponding to the upper Simeto valley, was invaded by the Ellittico volcano lava flows between 41 and 29 ka ago when the Mt Barca eruption occurred. The vent of this flank eruption is located at about 15 km away from the summit craters, close to the town of Bronte. The Mt Barca eruption was characterized by a vigorous explosive activity that produced pyroclastic deposits dispersed eastward and minor effusive activity with the emission of a 1.1-km-long lava flow. Explosive activity was characterized by a phreatomagmatic phase followed by a magmatic one. The geological setting of this peripheral sector of the volcano favors the interaction between the rising magma and the shallow groundwater hosted in the volcanic pile resting on the impermeable sedimentary basement. This process produced phreatomagmatic activity in the first phase of the eruption, forming a pyroclastic fall deposit made of high-density, poorly vesicular scoria lapilli and lithic clasts. Conversely, during the second phase, a typical strombolian fall deposit formed. In terms of hazard assessment, the possible occurrence of this type of highly explosive flank eruption, at lower elevation in the densely inhabited areas, increases the volcanic risk in the Etnean region and widens the already known hazard scenario.

    Chemical and isotopic compositions of thermal springs, fumaroles and bubbling gases at Tacaná Volcano (Mexico–Guatemala): implications for volcanic surveillance (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: This study presents baseline data for future geochemical monitoring of the active Tacaná volcano–hydrothermal system (Mexico–Guatemala). Seven groups of thermal springs, related to a NW/SE-oriented fault scarp cutting the summit area (4,100m a.s.l.), discharge at the northwest foot of the volcano (1,500–2,000m a.s.l.); another one on the southern ends of Tacaná (La Calera). The near-neutral (pH from 5.8 to 6.9) thermal (T from 25.7°C to 63.0°C) HCO3–SO4 waters are thought to have formed by the absorption of a H2S/SO2–CO2-enriched steam into a Cl-rich geothermal aquifer, afterwards mixed by Na/HCO3-enriched meteoric waters originating from the higher elevations of the volcano as stated by the isotopic composition (δD and δ18O) of meteoric and spring waters. Boiling temperature fumaroles (89°C at~3,600m a.s.l. NW of the summit), formed after the May 1986 phreatic explosion, emit isotopically light vapour (δD and δ18O as low as −128 and −19.9‰, respectively) resulting from steam separation from the summit aquifer. Fumarolic as well as bubbling gases at five springs are CO2-dominated. The δ13CCO2 for all gases show typical magmatic values of −3.6 ± 1.3‰ vs V-PDB. The large range in 3He/4He ratios for bubbling, dissolved and fumarolic gases [from 1.3 to 6.9 atmospheric 3He/4He ratio (RA)] is ascribed to a different degree of near-surface boiling processes inside a heterogeneous aquifer at the contact between the volcanic edifice and the crystalline basement (4He source). Tacaná volcano offers a unique opportunity to give insight into shallow hydrothermal and deep magmatic processes affecting the CO2/3He ratio of gases: bubbling springs with lower gas/water ratios show higher 3He/4He ratios and consequently lower CO2/3He ratios (e.g. Zarco spring). Typical Central American CO2/3He and 3He/4He ratios are found for the fumarolic Agua Caliente and Zarco gases (3.1 ± 1.6 × 1010 and 6.0 ± 0.9 RA, respectively). The L/S (5.9 ± 0.5)and (L + S)/M ratios (9.2 ± 0.7) for the same gases are almost identical to the ones calculated for gases in El Salvador, suggesting an enhanced slab contribution as far as the northern extreme of the Central American Volcanic Arc,Tacana

    Volcanological inferences from seismic-strain tensor computations at Mt. Etna Volcano, Sicily (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Kostrov's (1974) algorithm for seismic-strain tensor computations, in the version implemented by Wyss et al. (1992a) for error estimates, has been applied to shear-type earthquakes occurring beneath the Etna volcano during 1990-1996. Space-time variations of strain orientations and amplitudes have been examined jointly with ground-deformation and gravimetric data collected in the same period and reported in the literature. Taking also into account the information available from volcanological observations and structural geology, we propose a model assuming that hydraulic pressure by magma emplaced in nearly north-south vertical structures produces the E-W orientation of the maximum compressive strain found in the upper 10 km beneath the crater area. In contrast, regional tectonics deriving from the slow, north-south convergence between the African and European plates appear to play a dominant role in the generation of stress and strain fields at crustal depths deeper than 10 km below the volcano. According to our interpretation, the progressive ascent of magma through the upper crust prior to eruption produces the observed gravity changes, cone inflation and unusual seismic strain rate in the upper 10 km associated with a more sharply defined seismic deformation regime (i.e. very small confidence limits of the epsilon 1 orientation). In agreement with this model, deflation revealed by ground-deformation data during the course of the major 1991-1993 eruption was accompanied by a practically nil level of shallow seismicity.

    A topographic surface reduction of aeromagnetic anomaly field over the Tyrrhenian sea area (Italy) (2005)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: This paper shows the results of a detailed reprocessing of aeromagnetic data,obtained by the downward projection to the seabed. The area of interest is centered over the Tyrrhenian Basin,whose bathymetric –topographic lay-out is characterized by a somewhat irregular trend.The origin of the intense depth variations depends on the Tyrrhenian structural setting,that is associated with the presence of several tectonic lineaments,seamounts or volcanic islands.The data were characterized by good quality and dense sam- pling,but they have been reprocessed in order either to solve some problems in the original compilation,and to reduce the distor- tion of the geomagnetic anomaly field caused by the difference of distance between the survey level and the magnetic source.The reprocessed magnetic map is proposed as an e ffective analysis tool for the Tyrrhenian area that is characterized by high susceptibility lithotypes.Downward projection of the aeromagnetic data by BTM algorithm increases the de finition of the anomalous magnetic signal without distortions in the geometric pattern of the field,thus showing a more stable and effective association between the magnetic anomalies and their geological sources.This effect is particularly true for high frequency anomalies that are directly comparable after the topographic projection because the depth filtering effect is attenuated.Moreover,the BTM method has been applied for the first time to a regional scale survey that shows substantial advantages because no fictitious anomalies in the high frequency sector of the spectrum were generated.This has been a typical effect of the traditional downward projection methods widely used before.The final result is a BTM anomaly map that is able to show the structural connections between the geological magnetic sources of the Tyrrhenian Sea area.

    BET_EF: a probabilistic tool for long- and short-term eruption forecasting (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: The main purpose of this paper is to introduce a Bayesian event tree model for eruption forecasting (BET_EF). The model represents a flexible tool to provide probabilities of any specific event at which we are interested in, by merging all the relevant available information, such as theoretical models, a priori beliefs, monitoring measures, and any kind of past data. BET_EF is based on a Bayesian procedure and it relies on the fuzzy approach to manage monitoring data. The method deals with short- and long-term forecasting, therefore it can be useful in many practical aspects, as land use planning, and during volcanic emergencies. Finally, we provide the description of a free software package that provides a graphically supported computation of short- to long-term eruption forecasting, and a tutorial application to the recent MESIMEX exercise at Vesuvius.

    Fluorine speciation in topsoils of three active volcanoes of Sicily (Italy) (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Fluorine is one of the many environmental harmful elements released by volcanic activity. The content of total, oxalate extractable and water extractable fluorine was determined in 96 topsoils of three active volcanic systems of southern Italy (Mt. Etna, Stromboli and Vulcano). Total fluorine content (FTOT) ranges from 112 to 7430 mg kg-1, F extracted with oxalate (FOX) ranges from 16 to 2320 mg kg-1 (2 – 93 % of FTOT) and F extracted with distilled water (FH2O) ranges from 1.7 to 159 mg kg-1 (0.2 – 40 % of FTOT). Fluorine in the sampled topsoils derives both from the weathering of volcanic rocks and ashes and from enhanced deposition due to volcanic gas emissions either from open-conduit passive degassing (Mt. Etna and Stromboli) or from a fumarolic field (Vulcano). Fluorine accumulation in the studied soils does generally not present particular environmental issues except for a few anomalous sites at Vulcano where measured contents could be dangerous both for vegetation and for grazing animals.

    Investigation of pre-1700 Earthquakes Between the Adda and the Middle Adige River Basins (Southern Alps) (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: While the seismicity of the Southern Alps is high in the Eastern sector, corresponding to the Veneto and Friuli regions, it decreases towards West up to the Adda River. In the sector between the Lessini Mts. and Eastern Friuli the damaging earthquakes are clustered in a well defined seismic belt, where seismogenic sources responsible for earthquakes with Mw 6 have been defined in recent works. In contrast, the knowledge of the Southalpine sector West of this area is sparser; the area experienced some earthquakes with Mw〉5.5 and varied events with 4.8≤Mw≤5.5 the distribution of which is, apparently, random. For the area roughly defined by the basins of the Adda River to the West and the middle Adige River to the East, this paper reappraises the background knowledge of the earthquakes occurred before 1700. The investigation and the results are presented according to two successive periods, up to 1995 and from 1995 on. In the research performed up to 1995, the most important achievements concerned two different aspects: i) the assessement of several “fake quakes”, some of which were the object of paradigmatic case-histories; ii) the resizing and relocation of several, presumed damaging earthquakes. Though this round of investigation changed significantly the picture of the seismicity with respect to the Seventies, the research continued. For the period from 1995 on, the discussion focuses on the reliability of the available information; material that received little or no consideration before, new historical findings and comments to the seismological interpretation as in the most recent literature are also presented. This part includes also the discussion of archaeoseismological evidence of damage related to past earthquakes.

    In Troubled Times, in a Divided Country: The 1789 Valtiberina Earthquake (2008)
    Springer
    Details
    Publication Date: 2017-04-03
    Description: The Valtiberina region (central Italy) has a seismic record going back to the Middle Ages and including five Io 〉 VIII MCS earthquakes, the earliest of which (1352, 1389, 1458). though recently and extensively studied, remain rather poorly known. This makes it all the more important to ensure that the later ones (1789, 1917) are as throughly studied as possible. The 1789 earthquake is listed by the current Italian catalogue (CPTI Working Group 2004) with Io VIII-IX MCS and Mm 5.8. These parameters were assessed from a database of 28 macroseismic intensity data points (Castelli et al. 1996), which is less than plentiful for a late 18th century earthquake. An analysis of the historical context of the 1789 earthquake and its influence on the production of contemporary accounts evidences a few research paths that previous studies either did not or could not take. Following them, the macroseismic database of the 1789 earthquake can be noticeably improved, providing the catalogue compiler with a mean to check the reliability of its current parameters.

    Volcanic Eruptions:Cyclicity during Lava Dome Growth (2008)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: We consider the process of slow extrusion of very viscous magma that forms lava domes. Dome-building eruptions are commonly associated with hazardous phenomena, in- cluding pyroclastic flows generated by dome collapses, explosive eruptions and volcanic blasts. These eruptions commonly display fairly regular alternations between pe- riods of high and low or no activity with time scales from hours to years. Usually hazardous phenomena are asso- ciated with periods of high magma discharge rate, thus, understanding the causes of pulsatory activity during ex- trusive eruptions is an important step towards forecasting volcanic behavior, especially the transition to explosive ac- tivity when magma discharge rate increases by a few orders of magnitude. In recent years the risks have increased be- cause the population density in the vicinity of many active volcanoes has increased.

    Simulating Earthquake Scenarios in the European Project LESSLOSS: The Case of Lisbon (2008)
    Springer
    Details
    Publication Date: 2019-01-30
    Description: Within the framework of the European LESSLOSS Project “Risk Mitigation for Earthquakes and Landslides”, finite-fault seismological models have been proposed for the computation of earthquake scenarios for three urban areas: Istanbul (Turkey), Lisbon (Portugal) and Thessaloniki (Greece). For each case study, ground motion scenarios were developed for the two most probable events with different return periods (generally 50 and 500 years), locations and magnitudes that were derived from historical and geological data. The ground motion simulations were performed in the frequency band of engineering interest (0.5-20 Hz) by two numerical finite-fault methods: a hybrid deterministic-stochastic method, DSM, used for all of the cases investigated, and a non-stationary stochastic finite-fault simulation method, RSSIM, applied only in the case of Lisbon. In the present study, the results with respect to bedrock and surface are presented in terms of peak ground acceleration (PGA) for the city of Lisbon and the surrounding area, using earthquake scenarios from the onshore source area of the Lower Tagus Valley, and from the offshore source area of the Marques de Pombal fault, which is one of the possible sources of the 1755 Lisbon earthquake. Site effects are evaluated by means of a properly designed equivalent stochastic non-linear one-dimensional ground response analyses of stratified soil profile units. The requirements of the users (e.g., engineers, local administrators) constrain the choice of the scenario that can be adopted as input for disaster scenario predictions and loss modelling; in the case of Lisbon, the maximum values of shaking were assumed as the criteria for the reference scenarios.

    Publication Date: 2020-02-24
    Description: A high-resolution Fabry–Perot interferometer was inserted in a feedback loop which, by monitoring elements of the fringe pattern, keeps the position of the transmitting window fixed with respect to a given line, taking into account the instability of the radiation source which would produce a wander of the line itself and the noise affecting the tuning of the receiving interferometer. The system, in this preliminary form, is able to lock itself and maintain its position indefinitely for slow and moderately fast varying disturbances.

    Heavy metals distribution of soils around mining sites of cadmium-rich marine sedimentary phosphorites of Kpogamé and Hahotoé (Southern Togo) (2008)
    Springer
    Details
    Publication Date: 2021-05-19
    Description: Metal concentrations of 37 soil samples taken from mining areas (abandoned mine pits and transport routes) in Kpogamé and Hahotoé (southern Togo) range from 0.2-43 ppm for Cd, 15-115 ppm for Pb, 182-1,029 ppm for Cr, 18-356 ppm for Cu, 15-342 pm for Ni, 90-513 ppm for V, 35-536 ppm for Zn, 80-469 ppm for Zr and 266-3,161 ppm for Sr. The tropical alteration of the ore waste plays an important role in the distribution of trace elements in the studied soils. Because the alteration affects the element mobility, generally old abandoned mining areas, which , together with soils near the transport routes, show a higher degree of contamination. Under low pH and oxidising conditions in studied soils Cd, Ni and Zn are generally easily mobilised and are thus available to the environment.

    VLNDEF Project for Geodetic Infrastructure Definition of Northern Victoria Land, Antarctica (2008)
    Springer
    Details
    Publication Date: 2022-05-30
    Description: Scientific investigations in Antarctica are, for many different reasons, a challenging and fascinating task. Measurements, observations and field operations must be carefully planned well in advance and the capacity of successfully meeting the goals of a scientific project is often related to the capacity of forecasting and anticipating the many different potential mishaps. In order to do that, experience and logistic support are crucial. On the scientific side, the team must be aware of its tasks and be prepared to carry out observations in a hostile environment: both technology and human resources have to be suitably selected, prepared, tested and trained. On the logistic side, nations, institutions and any other organisation involved in the expeditions must ensure the proper amount of competence and practical support. The history of modern Italian Antarctic expeditions dates back to the middle 80’s when the first infrastructures of “Mario Zucchelli Station”, formerly Terra Nova Bay Station, were settled at Terra Nova Bay, Northern Victoria Land. Only a few years later, the first geodetic infrastructures were planned and built. Italian geodetic facilities and activities were, ever since, being constantly maintained and developed. Nowadays, the most remarkable geodetic infrastructures are the permanent Global Positioning System (GPS) station (TNB1) installed at Mario Zucchelli and the GPS geodetic network Victoria Land Network for DEFormation control (VLNDEF) entirely deployed on an area extending between 71° S and 76° S and 160° E and 170° E. These facilities do not only allow carrying out utmost geodetic investigations but also posses interesting capacities on the international multidisciplinary scientific scenario. In order to fully exploit their potentiality, management and maintenance of the infrastructure are crucial; nevertheless, in order to perform high quality scientific research, these abilities must be coupled with the knowledge concerning a proper use and a correct processing of the information that these infrastructures can provide. This work focuses on the different methods that can be applied to process the observations that are performed with GPS technique in Northern Victoria Land, aiming at reaching the highest accuracy of results and assuring the larger significance and versatility of the processing outcomes. Three software were used for the analysis, namely: Bernese v.5.0, Gipsy/Oasis II and Gamit/Globk. The working data sets are (i) the permanent GPS station TNB1 observations continuously performed since 1998 and (ii) the five episodic campaigns performed on the sites of VLNDEF. The two infrastructures can be regarded as neat examples of standard geodetic installation in Antarctica. Therefore, the technological solutions that were adopted and applied for establishing the GPS permanent station and the VLNDEF geodetic network as well as the data processing strategies and the data analysis procedures that were tested on their observation will be illustrated in detail. The results will be presented, compared and discussed. Furthermore, their potentials and role in geodetic research will be carefully described; their versatility will also be highlighted in the foreground of a multidisciplinary Antarctic international scientific activity.

    Correlation between damage distribution and ambient noise H/V spectral ratio: the SESAME project results (2008)
    Springer
    Details
    Publication Date: 2022-05-24
    Description: In the framework of the SESAME project one of the taskswas the compilation of all available ambient noise measurements within urban environments affected by historical or/and recent strong earthquakes in Europe. The aim of such a task was to give an answer to the question; “How does horizontal-to-vertical ambient noise spectral ratio compare with damage in modern cities?”. For this purpose five European urban areas, namely, Angra do Heroismo (Portugal), Fabriano and Palermo (Italy), Thessaloniki and Kalamata (Greece) were selected for which spatial damage information was available either in terms of modified Mercalli intensity or in EMS98 damage grades. The geological setting of the examined sites as well as the causative earthquakes are satisfactorily known. Ambient noise recordings compiled for all examined sites have been homogeneously processed by a technique developed and agreed upon SESAME project. Using a standard multivariate statistical analysis, namely, factor analysis and canonical correlation, the horizontal-to-vertical ambient noise spectral ratio (HVNSR) is correlated with damage pattern observed within examined urban areas. Results show that, in some cases (Thessaloniki, Palermo), the HVNSR seems to be able to differentiate between areas previously shown to be associated with higher damage. In other cases however (Angra do Heroismo, Fabriano, Kalamata), the correlation is not statistically significant indicating thus the complex character of the parameters involved, implying that currently there is no a straightforward way that a value of HVNSR can correctly predict the extent to which a given region will be associated with increased damage.

    Deriving vulnerability curves using Italian earthquake damage data (2008)
    Springer
    Details
    Publication Date: 2022-05-24
    Description: The concerted effort to collect earthquake damage data in Italy over the past 30 years has led to the development of an extensive database from which vulnerability predictions for the Italian building stock can be derived. A methodology to derive empirical vulnerability curves with the aforementioned data is presented herein and the resulting curves have been directly compared with mechanics-based vulnerability curves. However, it has been found that a valid comparison between the empirical and analytical vulnerability curves is not possible mainly due to a number of shortcomings in the database of surveyed buildings. A detailed discussion of the difficulties in deriving vulnerability curves from the current observed damage database is thus also presented.

    Notes: Purpose - This UK-based research aims to build on the US-based work of Keller and Aaker, which found a significant association between "company credibility" (via a brand's "expertise" and "trustworthiness") and brand extension acceptance, hypothesising that brand trust, measured via two correlate dimensions, is significantly related to brand extension acceptance. Design/methodology/approach - Discusses brand extension and various prior, validated influences on its success. Focuses on the construct of trust and develops hypotheses about the relationship of brand trust with brand extension acceptance. The hypotheses are then tested on data collected from consumers in the UK. Findings - This paper, using 368 consumer responses to nine, real, low involvement UK product and service brands, finds support for a significant association between the variables, comparable in strength with that between media weight and brand share, and greater than that delivered by the perceived quality level of the parent brand. Originality/value - The research findings, which develop a sparse literature in this linkage area, are of significance to marketing practitioners, since brand trust, already associated with brand equity and brand loyalty, and now with brand extension, needs to be managed and monitored with care. The paper prompts further investigation of the relationship between brand trust and brand extension acceptance in other geographic markets and with other higher involvement categories.

    Notes: Purpose - Aims to explore the factorial structure of automobile brand image in the context of a cross-national study. More specifically, we intend to answer two questions: whether the factor structure of brand image perception differ across countries, and whether these differences are owing to nation's culture and level of economic development. Design/methodology/approach - An existing data set, which consists of data collected from survey research, was employed. Data covering the top 20 automobile markets consisting of 4,320 eligible new car owners. Perception of and attitude towards automobile brand associations were measured using nominal scales. Findings - Provides empirical evidence that supports the applicability of multiple brand image dimensions corresponding to the consumer's sensory, utilitarian, symbolic and economic needs at the global level. The study also suggested that factor structure of brand image differs across nations and these differences might be reflective to a nation's culture and its level of economic development. Research limitations/implications - As with any empirical study, this research inevitably has its limitations, which presents opportunities for further research: extensions of the present framework to other product categories; extensions of the national factors; extensions of the brand associations; and measurement improvement. Practical implications - Understanding the similarities or differences of the factor structure of brand image across the globe facilitates the formation of a successful global image strategy. First of all, by exploring brand image structure at the global level; and the specific interrelationships among the corresponding associations Originality/value - The results derived from the 20 diverse nations in the present study not only enhance our understanding of brand image structure but also provide a strong test of the empirical generalizability of automobile brand image dimensionality and factor structure in a global context.

    Notes: Purpose - Innovation launch strategies are usually critical for innovation success. The main objective of this work consists of analysing the influence of the tactical launch decisions on new product performance Design/methodology/approach - Starts with a brief literature review. Then the results obtained in our study are compared with those obtained in other research. The data used in our research describes a new product launch in the Spanish agro-food sector. The method for collecting the information was through a mailed questionnaire. Because most of response variables were categorical, and in order to verify the proposed hypotheses, cross tabulation was used. We used Pearson's chi-squared (?2), likelihood ratio (H2) and the adjusted residuals too. Findings - The results propose a series of recommendations for the executives in charge of marketing new products. Specifically, suggests that it will be more likely to achieve success if, when launching a new product, skimming strategies are used, if intensive distribution is used for selling an innovation and the investment in the communication media is greater than that made by competitors. However, it is more possible to fail if the new product is marketed using an individual brand, penetration prices, push communication strategies and less expenditure on this concept than the competitors. Research limitations/implications - The literature review suggests that some of these tactical decisions seem to be related with other launch decisions (strategic launch decisions). As a result of this, it will be interesting to perform these similar analyses for those as well as to analyse the possible links that may exist between both and their influence on the results. Future research could explore these relationships in other industrial sector or countries. Perhaps, it would be possible provide a common perspective. Originality/value - In spite of the importance of the last phase of new product, there are few empirical works about it. This work tries to explain the transcendence of the tactical launch decisions and the influence of it on the success/failure of an innovation

    Notes: Purpose - The paper attempts to answer "Will the shift from the locus of self to locus of others impact the magnitude of loss aversion?" and "Will different prices affect the self-other asymmetry in choice?". Design/methodology/approach - The design is a two (locus: self vs others) by two (anchoring price: $30 vs $90) between-subjects' factorial with both the locus of evaluation and the monthly service plan charges (anchoring prices) as the between-subjects' factors. Findings - The author finds that inertia equity is smaller when consumers evaluate peer customers than when they evaluate themselves to switch brands. It is also found that the locus effect is applicable to brands at various prices. Research limitations/implications - Further research should focus on the validations of the assumptions to support the empirical finding from the theoretical perspective. Practical implications - Price reductions should be made personally relevant to the consumer and price increases should be made relevant to other things. Originality/value - The locus effect expands the assessment of loss aversion from one (self or other) to two dimensions jointly (self and other). It demonstrates the impact of the locus of evaluation on the magnitude of loss aversion.

    Topics: Economics
    Notes: Purpose - The paper proposes investigating the timing of consumer requests for price-matching refunds, the relationship between the refund timing and consumer repeat store purchase and the reasons for buying from the price-matching store when a lower competitive price is found before purchase. Design/methodology/approach - In Study 1, qualitative research (consumer interviews) was conducted; Study 2 uses a shopping simulation in which the timing of consumer refund-seeking behavior is observed, and Study 3 involves a consumer survey in which information on consumer refund-seeking behavior at real stores is gathered. Findings - The paper finds that consumers request price-matching refunds more frequently at the time of purchase than after the purchase. Seeking (and receiving) the price-matching refund is associated with higher repeat store purchase behavior than not having had a refund-seeking experience. Key reasons for buying from the price-matching retailer when a lower competitive price is found before purchase include convenience, tangible extras, and store reputation/service quality. Research limitations/implications - A student convenience sample was used. In Study 2, fictitious stores were used. In Study 3, the timing of refund seeking may have been different on other (not reported) occasions. Ability to seek the refund was not accounted for. Practical implications - The majority of the retailer's price-matching cost will come from issuing at-the-time-of-purchase refunds, when consumers possess more bargaining power. A positive refund-seeking experience may create a more loyal customer. In addition to being a low-price signal, price-matching policies can serve as signs of retailers' customer orientation. Originality/value - This research fills the gap in understanding the consumer price-match refund-seeking behavior and offers practical implications for retailers employing price-matching guarantees.

    Notes: Purpose - The paper aims to report the findings of research into perceptions of what makes the Private Finance Initiative (PFI) attractive or unattractive as a procurement system for projects in the UK. Design/methodology/approach - The research uses a postal survey questionnaire technique for primary data collection. Literature review is used to identify relevant factors, which are then incorporated into the design of the survey instrument. Survey response data is subjected to descriptive statistical analysis and subsequently to rotated factor analysis. Findings - Public/private partnerships (PPP)/PFI project procurement is perceived as most attractive in terms of positive factors relating to better project technology and economy, greater public benefit, public sector avoidance of regulatory and financial constraints, and public sector saving in transaction costs. Negative aspects, relating to factors such as the inexperience of the participants, the over-commercialisation of projects, and high participation cost and time, make PPP/PFI procurement less attractive. Originality/value - The procurement of public facilities and services under arrangements involving partnerships between the public and private sectors is claimed to provide a wide variety of net benefits to the public sector and to the private sector participants. In the project development process, the parties have to make decisions based on suitable evaluation criteria. At the early stage of preparing a business case, a clear and common understanding of the positive and negative factors surrounding PPP/PFI procurement will provide a more informed basis for decision making.

    Notes: Purpose - Housing Associations in the UK are being encouraged to change the way in which they procure their building projects. This work aims to provide a snapshot of current practice in relation to the use of partnering as a procurement approach. Design/methodology/approach - Accordingly a quantitative research design was used to capture data from a sample of 100 of the largest Housing Associations involved in the commissioning of new house building projects in 2003. Two administrations of the survey generated a 43 per cent response rate. Findings - The findings of the study revealed that two differing types of partnering alliance could be identified. The types of partnering alliance identified were considered to have either a "supply side" or "demand side" focus. The results show that partnering practice, open-book cost management, risk analysis and the use of standardised and pre-fabricated components are now widespread and believed to deliver benefits in project costs, delivery times and quality levels. Research limitations/implications - The work is limited due to the size of the sample frame and the measuring instrument used which could not uncover reasons for the current practices that were revealed. Practical implications - The outcomes of the work provide practice with benchmarks that can be used to evaluate organisational approach and if necessary develop alternative approaches to the delivery of partnered projects. Originality/value - The paper contributes to the body of knowledge available on partnering practice in a client group that has been identified as being key in driving forward the post-Egan agenda in the construction industry.

    Notes: Purpose - The selection and use of the most appropriate building project contract price forecasting model contribute to the provision of strategic advice that clients can use to make value-for-money business decisions. This work seeks to provide a snapshot of current practice in model selection by practitioners based in large-sized quantity surveying, project management and multi-disciplinary practices based in the UK. Design/methodology/approach - A quantitative research design was used to capture data from a sample of 300 such organisations in 2004. An initial and follow-up administration of the postal survey generated an overall response of 54 per cent. Findings - The findings of the study revealed that the traditional types of forecasting model continue to be in widespread use irrespective of organisational type. Lifecycle cost models and in-house knowledge-based systems were also found to be in use, but not on such a widespread scale. Newly developed models such as artificial neural nets, fuzzy logic nets, as well as environmental and sustainability cost models were found, as yet, to have only very limited application in practice. Practitioner assessment of model accuracy and value in-use provided statistically insignificant levels of variance between the organisational types and the models found to be in use. Research limitations/implications - The work is limited due to the size of the sample frame and the measuring instrument used which could not uncover reasons for the selection of particular types of models. Originality/value - The outcomes of the work provide benchmarks that can be used to evaluate organisational approach and future research. The paper contributes to the body of knowledge available on the process of building project contract price forecasting that is fundamental to the assessment of project value.

    Worker safety issues in night-time highway construction (2005)
    Oxford : Emerald
    Engineering, construction and architectural management 12 (2005), S. 487-501

    Notes: Purpose - The research presented in this paper aims to investigate highway construction/maintenance professionals' perceptions of the effects of night-time construction conditions on worker visibility and of issues associated with safety vests in night-time activities. Design/methodology/approach - The research was conducted by administering a questionnaire survey to Illinois Department of Transportation operations personnel, resident engineers, contractors, and construction/maintenance professionals involved in night-time construction in the Departments of Transportation of states other than Illinois. Findings - It was found that most accidents in night-time construction work areas are caused by the condition of the vehicle operator, that accidents are caused by through-traffic and construction equipment operating inside the work area, and that the poor visibility of the workers plays an important role in accidents. Research limitations/implications - A national survey (rather than mostly Illinois personnel) would certainly increase the sample size and therefore allow researchers to validate the findings of this study and to conduct extensive statistical analyses. Practical implications - Night-time construction/maintenance operations on highways may be hazardous for both drivers and construction personnel because of poor visibility at night. It is recommended that the design of safety vests adhere to existing standards issued by the American National Standards Institute and the International Safety Equipment Association. It is particularly important to ensure adequate performance in wet weather conditions. Originality/value - If safety vests are perceived by workers to be effective, the frequency and severity of night-time accidents can be reduced and labor productivity can be enhanced.

    Use of process maps to develop a management briefing sheet for a design consultancy (2005)
    Oxford : Emerald
    Engineering, construction and architectural management 12 (2005), S. 458-469

    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Purpose - Process mapping can lead to a more holistic understanding of how an organisation works. This paper seeks to discuss how an engineering design consultancy, which had developed a series of process maps on the design of steel frame buildings, developed a powerful management tool, the Management Briefing Sheet which has yielded numerous additional benefits enabling practice to be improved and quality procedures more easily accessed. Design/methodology/approach - To maximise the knowledge and expertise of its supply chain partners and to better understand how it designed steel-framed buildings, the engineering design consultancy undertook a process-mapping exercise. Various techniques for documenting the process were considered, but a modified IDEF notation was chosen for its ability to capture the iterative nature of the design process and its methodical approach for deconstructing complicated activities. Findings - Process-mapping exercises can change the way organisations work and make them more efficient, but to do this the changes that would lead to improvements need to be implemented successfully. Carrying out a process-mapping exercise in isolation from the end-user can lead to complications. Research limitations/implications - The key obstacle to implementing change identified by the engineering design consultancy, with whom the MBS was developed, was delivering the knowledge acquired from the process analysis in a format that end-users could understand easily and adopt effectively. Originality/value - This article will be of significant use to any organisation wishing to maximise the knowledge and expertise of its supply chain partners and identify inefficient working practices.

    Process models implementation in the construction industry: a literature synthesis (2005)
    Oxford : Emerald
    Engineering, construction and architectural management 12 (2005), S. 470-486 
    Details
    ISSN: 1365-232X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Purpose - Different process models have been developed by academia and industry to enhance the effectiveness and efficiency of the design and construction activity in response to the need for improving performance. However, the effective and widespread adoption and use of process models have been limited, and the benefits resulting from these endeavours have been ambiguous at best and non-existent at worst. This paper synthesises the key general and construction-specific literature related to process model implementation around a generic model, providing a systematic picture on the current knowledge on implementation. Design/methodology/approach - Secondary data sources were reviewed, criticised and synthesised. The books and academic papers identified focused on the areas of process management in construction and manufacturing, change management and knowledge/technology transfer. Findings - The paper concludes that the body of literature related to process model implementation lacks an integrated focus and cohesion, and the need to appropriately locate and operate the implementation strategy within a visible organisational context is not adequately addressed. Research limitations/implications - The paper review and synthesis are limited to relevant literature within the context of implementation of process models. Practical implications - Gaps in the literature are identified and discussed, and a set of questions proposed to stipulate future research. Originality/value - The paper originality relates to providing a broad, systemic perspective on the complexity of process models implementation, analysing it from different but interrelated conceptual lenses.

    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Architecture, Civil Engineering, Surveying
    Notes: Purpose - Popularity in knowledge management has, unfortunately, not been matched by parallel empirical research on the processes, challenges and benefits of knowledge capture in small and medium enterprises (SMEs) in the construction industry, given the fact that 99 per cent of firms in the UK construction industry can be classified as SMEs. This paper aims to discuss the output of a research study, which is focused on knowledge capture in SMEs in construction industry. The paper also aims to present and discuss a computer-based awareness tool on knowledge capture underpinned by Kolb's experiential learning theory. Design/methodology/approach - The empirical study involved a total of 51 professionals from 26 SMEs in the construction industry. Grounded theory approach was adopted. Also, a content analysis was considered. Findings - The results show that there is lack of awareness of complex issues associated with an effective knowledge capture process as well as ensuing benefits for SMEs in the construction industry. The effective implementation of knowledge capture in SMEs is partly dependent on the vision and flair of the owner/partners of the organisation. It is also determined by culture, structure, people, finance and technology, which warrants a coherent and structured approach. Originality/value - A computer-based awareness tool which is underpinned by Kolb's experiential learning theory.

    Notes: Purpose - The main objective of this study is to develop a framework for: identifying the reasons for using e-commerce; understanding the implications of e-commerce in companies; and implementing and applying e-commerce successfully for improved organizational competitiveness and success. Design/methodology/approach - A structured questionnaire was designed, pre-tested, modified, and used to capture data on e-commerce in Hong Kong. Based on the feedback from the pilot-test, the questionnaire was modified and a final questionnaire was developed and mailed to companies in Hong Kong. In the survey, conducted with Hong Kong companies, the perceived benefits and perceived barriers of e-commerce implementation are discussed. Findings - The conceptual model based on the analysis of literature and some reported case experiences is developed using the current issues that have been highlighted as important e-commerce success factors of implementation. The major factors that influence the application and implementation of e-commerce are: perceived usefulness of web; perceived barriers of the internet for e-commerce; usage of the internet; and perceived benefits of the internet for e-commerce. In addition to this, country-specific factors such as culture, technology competency, government policy, educational level, influence the level of application of e-commerce. Practical implications - The framework is the result of the validation of the theoretical model, together with the conclusions of the empirical analysis conducted in Hong Kong. The empirical analysis supported some of the assumptions of the theoretical model, whereas others were not supported. Based on the feedback received from respondents, the model has been revised to reflect these practical considerations. Originality/value - Little research has been done to address the perceived benefits and potential barriers to e-commerce implementation in Hong Kong. This study is a timely and important one in that examines the current status of e-commerce implementation in Hong Kong. A generic framework is presented with the objective of supporting the application and implementation of the internet for e-commerce.

    Notes: Purpose - Although the wireless internet attracts more and more interest from marketers and researchers, there is little empirical evidence of multinational corporations' (MNCs) adoption of push-type mobile advertising in global markets. The aim of this study is to fill this research gap, by conducting an empirical survey of the perceptions of MNCs operating in Europe regarding SMS-based mobile advertising adoption. Design/methodology/approach - The study proposes six basic constructs which are thought to influence MNCs' decision-making process on mobile advertising adoption. On this base, a structured questionnaire is developed. The data are obtained by telephone interviews from 53 senior executives of MNCs' subsidiaries in Spain. Findings - Hierarchical regression analysis reveals that branding strategy, facilitating conditions, and security and costs are the strongest determinants of MNCs' mobile advertising adoption. Furthermore, discriminant analysis indicates that Japanese, American, and European firms are statistically classifiable according to their cultural affiliation in terms of their perceptions of mobile advertising adoption. Japanese firms are the least willing to use mobile advertising, while their American counterparts are the most motivated in this regard. Originality/value - While SMS-based mobile marketing has been receiving an increasing attention from both academics and practitioners, there exists little empirical research on this area. In this vein, this study contributes to the literature in two ways. First, the study proposes a conceptual research model based on six basic constructs, which incorporate both theoretical and practical perspectives. Second, the model is tested by empirical data obtained from top managers of MNCs' subsidiaries operating in a European market. The findings of this study thus offer useful insights based on their "hands-on" experience.

    Topics: Computer Science
    Notes: Purpose - To describe consumers' heuristic and analytical searches for a pre-purchase information acquisition, and to assess the correspondence of flexibility of information task and the information found with a search. Design/methodology/approach - Propositions based on current research in web use and consumer studies. Tracked records of searches are used for descriptive analysis of transitional patterns in the data. Regression is used for statistical verification of the information provided by searches. Findings - Consumer searches center on chaining events, indicating heavy reliance on hyperlink navigation between web sites. Formal searches are seldom used, although when employed, tend to have a high level of diagnosticity. The emphasis on heuristic behavior is logical, as the way consumer information is currently presented on the internet rewards for this type of behavior. Use of heuristic search increases the likelihood of access to flexibly presented information. Research limitations/implications - Consumers favor heuristic trial-and-error searches even in focused fact-finding search tasks, which are typically considered the domain of analytical seeking. Consumers seem to benefit most from apparently inefficient, reactive and heuristic searches, because these are more likely to provide information in a format that the consumer can adapt. Convenience sample limits generalizability of findings. Originality/value - While there is an increasing body of knowledge concerning internet use for finding information, fewer studies have focused on consumer uses of the web in search. This paper provides new information of online consumers, an increasingly important topic.

    Notes: Purpose - To provide a thorough analysis of the role of the internet in survey research and to discuss the implications of online surveys becoming such a major force in research. Design/methodology/approach - The paper is divided into four major sections: an analysis of the strengths and potential weaknesses of online surveys; a comparison of online surveys with other survey formats; a discussion on the best uses for online surveys and how their potential weaknesses may be moderated; and an overview of the online survey services being offered by the world's largest research firms. Findings - If conducted properly, online surveys have significant advantages over other formats. However, it is imperative that the potential weaknesses of online surveys be mitigated and that online surveys only be used when appropriate. Outsourcing of online survey functions is growing in popularity. Practical implications - The paper provides a very useful source of information and impartial advice for any professional who is considering the use of online surveys. Originality/value - The paper synthesizes the vast literature related to online surveys, presents original material related to survey methodology, and offers a number of recommendations.

    Notes: Purpose - To arouse the public awareness of online gaming-related crimes and other societal influences so that these problems can be solved through education, laws and appropriate technologies. Design/methodology/approach - A total of 613 criminal cases of online gaming crimes that happened in Taiwan during 2002 were gathered and analyzed. They were analyzed for special features then focusing on the tendency for online gaming crime. Related prosecutions, offenders, victims, criminal methods, and so on, were analyzed. Findings - According to our analysis of online gaming characteristics in Taiwan, the majority of online gaming crime is theft (73.7 percent) and fraud (20.2 percent). The crime scene is mainly in internet cafés (54.8 percent). Most crimes are committed within the 12:00 to 14:00 time period (11.9 percent). Identity theft (43.4 percent) and social engineering (43.9 percent) are the major criminal means. The offenders (95.8 percent) and victims (87.8 percent) are mainly male and offenders always proceed alone (88.3 percent). The age of offenders is quite low (63.3 percent in the age range of 15-20), and 8.3 percent of offenders are under 15 years old. The offenders are mostly students (46.7 percent) and the unemployed (24 percent), most of them (81.9 percent) not having criminal records. The type of game giving rise to most of the criminal cases is Lineage Online (93.3 percent). The average value of the online gaming loss is about US$459 and 34.3 percent of criminal loss is between $100 and $300. Research limitations/implications - These criminal cases were retrieved from Taiwan in 2002. Some criminal behavior may have been limited to a certain area or a certain period. Practical implications - Provides a useful source of information and constructive advice for the public who will sense the seriousness and influence of online gaming crimes. Further, this topic may have implications on e-commence, e-services, or web-based activities beyond gaming. Originality/value - Since there is little published research in this area, this paper provides the public with a good and original introduction to a topic of growing importance.

    Topics: Computer Science
    Notes: Purpose - This work aims to probe how interface designers concerned with human-computer interaction of community networks might use the theoretical constructs of social capital and activity awareness. Design/methodology/approach - A design model for community network interfaces is introduced that reconciles various computer-mediated communication research contributions with support for typical community network scenarios of use. Using this model, an inspection is performed on existing community network implementations (available December 2002) and then the adequacy of the model for informing the design process is examined. Findings - Based on the insight gained through this analysis, a generic prototype and new user evaluation method are introduced that allow survey of user reaction to community network design elements under differing conditions. It is shown how results obtained through this method frame a value-chain understanding of conceptual tradeoffs. Research limitations/implications - To demonstrate the new user evaluation method in an analysis of critical design tradeoffs, the issues of persistent virtual identity implementation and usage motivation are probed. However, the evaluation method must be validated with other issues and tested by researchers that were not part of its creation process. Practical implications - Contributions from this paper include tools (a design model, a generic prototype, and an evaluation method) linking theory with community design artifacts, building on previous work. Evaluators now have indicators for assessing community informatics. Originality/value - Interface designers of community networks and those interested in social capital theory will appreciate the link between practice and theory provided by this approach.

    Notes: Purpose - E-consumers consistently complain that the internet is frustratingly slow. Most existing research on this phenomenon is based on the concept of "download delay", that is, the time required for a web page to fully download to the e-consumer's computer screen. This paper reports on an exploratory study of the phenomenon of waiting for service on the internet with the intention of extending the narrow conceptualisation of the phenomenon of "download delay" to a more user-based perspective of waiting on the internet. Design/methodology/approach - The study is based on a qualitative research methodology. The research methods are seven asynchronous virtual focus groups involving 126 intensive internet users over 17 days and 92 participants who maintained personal diaries of waiting on the internet over a nine-week period. Findings - A new definition of waiting on the internet is proposed based on extensive virtual focus group research. Subsequently, 14 distinct types of internet waiting situations are identified based on the analysis of a total of 1,041 waiting situations as reported by the participants in the study. Practical implications - A number of practical implications for various functional areas of the business are outlined. Conceptual and methodological contributions are also made. Originality/value - The study is the first to present a broader conceptualisation of waiting on the internet from an e-consumer perspective and based on empirical research. All previous research has been based on just one type of online waiting, i.e. waiting for web pages to download to the user's screen. This paper presents 13 "new" types of waiting situations on the internet.

    Notes: Purpose - Using Internet Archive's Wayback Machine, higher education web sites were retrospectively analyzed to study the effects that technological advances in web design have had on accessibility for persons with disabilities. Design/methodology/approach - A convenience sample of higher education web sites was studied for years 1997-2002. The homepage and pages 1-level down were evaluated. Web accessibility barrier (WAB) and complexity scores were calculated. Repeated measures analysis of variance (ANOVA) was used to determine trends in the data and Pearson's correlation (r) was computed to evaluate the relationship between accessibility and complexity. Findings - Higher education web sites become progressively inaccessible as complexity increases. Research limitations/implications - The WAB score is a proxy of web accessibility. While the WAB score can give an indication of the accessibility of a web site, it cannot differentiate between barriers posing minimal limitations and those posing absolute inaccessibility. A future study is planned to have users with disabilities examine web sites with differing WAB scores to correlate how well the WAB score is gauging accessibility of web sites from the perspective of the user. Practical implications - Findings from studies such as this can lead to improved guidelines, policies, and overall awareness of web accessibility for persons with disabilities. Originality/value - There are limited studies that have taken a longitudinal look at the accessibility of web sites and explored the reasons for the trend of decreasing accessibility.

    Notes: Purpose - The objective of the paper is to identify the factors that encourage consumers to adopt internet banking services in Thailand and to use the study's findings to develop strategies for banks on how to maximize the rate of adoption. Design/methodology/approach - Quantitative research with a sample size of 600 achieved by sending questionnaires to 15 people in each of 40 large companies in Bangkok. The study is based on the Decomposed Planned Behaviour. Findings - The attitudinal factors that appear to encourage the adoption of internet banking in Thailand most are "Features of the web site" and "Perceived usefulness", while the most significant impediment to adoption is a perceived behavioural control, namely "External environment". The significant moderating factors are gender, educational level, income, internet experience and internet banking experience, but not age. Research limitations/implications - In this study, encouragement factors are those that are able to be controlled by banks, while impediment factors are those that are not able to be controlled. Practical implications - It is essential for banks to facilitate encouragement and restrict impediment factors. In addition to the direct "push" from internet banks (in respect of the encouragement factors), indirect persuasion should be carried out as a "pull" mechanism (in respect of the impediment factors). Originality/value - The study identified a number of specific strategies that Thai banks could follow to maximize the adoption of internet banking.

    Topics: Computer Science
    Notes: Purpose - The purposes of this study are to examine internet users' perception of potential harm among a list of products available on internet auction sites, to discuss the influence of the third-person effect on internet users' pro-regulatory attitudes, and to investigate the effects of users' characteristics and perceived harm on their attitudes toward regulation of online auction industry. Design/methodology/approach - An online questionnaire survey was designed and employed to collect information about internet users' third-person effect perception, pro-regulatory attitudes toward internet auction sites, and control variables such as demographics, internet usage, and innovative characteristics. A convenience sample of 592 internet users was recruited to take part in this study. Findings - Internet users' perceptual differences are statistically significant between the estimated influence on self, teenagers, and other adults for each product. Perceived harm to self consistently predicts internet users' pro-regulatory attitudes, but not for teenagers and other adults. Perceived harm to self also predicts pro-regulatory attitudes toward these web sites, even after controlling for potential confounding variables. Research limitations/implications - The study is limited by its convenient sampling method and measurement of internet users' actual and intended behavior. Nevertheless, because internet users play a complex role of buyers, sellers, and possible victims on auction sites, it is important to examine perceptions and motivations underlying their support for regulating online auction industry. Originality/value - The integrated approach of mass communication, electronic commerce activities, and public policy-making perspectives ensures that future regulatory proposal of online auction industry will be comprehensive.

    Notes: Purpose - First, to theoretically justify and empirically test the sequence of effects based on the standard learning hierarchy to explain consumers' online buying-related responses. Second, to analyse the moderating role that consumers' internet expertise can play on the formation of both their affective and buying-related responses towards this medium. Design/methodology/approach - This study poses a conceptual model which is tested by means of LISREL. The data used come from a questionnaire applied to American and Spanish internet users. These two countries have been selected taking into account their differences regarding their degree of internet expertise. Findings - The modelling approach appears to be adequate to explain online consumer behaviour. Moreover, different levels of consumers' internet expertise determines, in general, the predominance of the central or the peripheral route within the formation of their affective and behavioural responses to this medium. Research limitations/implications - This study provides a relevant contribution to the field of consumer behaviour on the internet. It presents an extensive literature review; it introduces new concepts and new relations among them; it successfully adapts classic consumer theories, i.e. the CAB paradigm and the Elaboration Likelihood Model - to the electronic market context; and it has a cross-national vision. Practical implications - It shows how any virtual firm which endeavours to understand consumers' shopping behaviour in its web site should consider these general issues in conjunction with the rest of the specific factors and variables related to it. Originality/value - This is one of the first studies which, on the one hand, theoretically integrates in a model the following concepts: beliefs and attitude towards the internet, trust in internet shopping and online shopping, and on the other, demonstrates that the degree of internet expertise plays an essential role in determining how consumers process and form their affective and buying-related responses on the internet.

    Notes: Purpose - To propose a model of a privacy-enhanced catalogue search system (PECSS) in an attempt to address privacy threats to consumers, who search for products and services on the world wide web. Design/methodology/approach - The model extends an agent-based architecture for electronic catalogue mediation by supplementing it with a privacy enhancement mechanism. This mechanism introduces fake queries into the original stream of user queries, in an attempt to reduce the similarity between the actual interests of users ("internal user profile") and the interests as observed by potential eavesdroppers on the web ("external user profile"). A prototype was constructed to demonstrate the feasibility and effectiveness of the model. Findings - The evaluation of the model indicates that, by generating five fake queries per each original user query, the user's profile is hidden most effectively from any potential eavesdropper. Future research is needed to identify the optimal glossary of fake queries for various clients. The model also should be tested against various attacks perpetrated against the mixed stream of original and fake queries (i.e. statistical clustering). Research limitations/implications - The model's feasibility was evaluated through a prototype. It was not empirically tested against various statistical methods used by intruders to reveal the original queries. Practical implications - A useful architecture for electronic commerce providers, internet service providers (ISP) and individual clients who are concerned with their privacy and wish to minimize their dependencies on third-party security providers. Originality/value - The contribution of the PECSS model stems from the fact that, as the internet gradually transforms into a non-free service, anonymous browsing cannot be employed any more to protect consumers' privacy, and therefore other approaches should be explored. Moreover, unlike other approaches, our model does not rely on the honesty of any third mediators and proxies that are also exposed to the interests of the client. In addition, the proposed model is scalable as it is installed on the user's computer.

    Notes: Purpose - To use the theory of planned behavior (TPB) as a theoretical framework to explore in depth the range of beliefs held by consumers about internet shopping in general and internet grocery shopping in particular. Design/methodology/approach - Seven focus group interviews, four in the United Kingdom and three in Denmark, were conducted among consumers with different degrees of experience with internet grocery shopping. This diversification of respondents was chosen to capture a broad range of the consumer beliefs that predict intentions to buy groceries online or not. The TPB framework was used to construct the interview guide that was followed in all focus groups. Findings - An unexpected result of the explorative study was that the seven groups consisting of more or less experienced internet shoppers differed only little in their pool of beliefs (outcome and control beliefs). Beliefs about internet grocery shopping, positive as well as negative, were remarkably congruent across groups. In the minds of consumers, internet grocery shopping is an advantage compared with conventional grocery shopping in terms of convenience, product range and price. Disadvantages, which could act as mental barriers, are, for instance, the risk of receiving inferior quality groceries and the loss of the recreational aspect of grocery shopping. Research limitations/implications - An important potential limitation of this research is the choice of focus groups as research methodology, which can prevent the elicitation of certain types of beliefs. If important beliefs concern issues of a more sensitive, personal character they are not likely to be mentioned in a focus group. Another limitation is the explorative nature of the research, which makes it impossible to attach weights to the importance of the elicited beliefs in predicting internet shopping behavior. Practical implications - The findings could be used to direct attention to consumer beliefs about internet grocery shopping which have the potential of acting as barriers to this line of e-commerce. Originality/value - To shed some light on the role of consumers in an underperforming and understudied branch of internet retailing. Barriers in the consumers' minds to shop for groceries online are identified using an established theoretical framework.

    Notes: Purpose - The objective of this paper is to investigate the legal and technical reasons why a declaration of will, denoted by a digital signature, can be cancelled and how this cancellation can be technically achieved. Design/methodology/approach - Proposes a technical framework for establishing a signature revocation mechanism based on special data structures, the signature revocation tokens (SRT), and investigates the alternatives for disseminating the signature status information (SSI) to the relying parties. Findings - A relying party has to take into consideration the possible existence of a signature revocation, in order to decide on the validity of a digital signature. A scheme based on a central public repository for the archival and distribution of signature revocation tokens exhibits significant advantages against other alternatives. Originality/value - Identifies various intrinsic problems of the digital signature creation process that raise several questions on whether the signer performs a conscious and wilful act, although he/she is held liable for this action. The law faces the eventual right of the signer to claim a revocation of a previously made declaration of will, especially in cases of an error, fraud or duress.

    Notes: Purpose - To analyze the relationship between corporate image and consumer trust in the context of financial services distribution. Design/methodology/approach - This paper analyzes the causal relationship that exists between corporate image and consumer trust in the financial services distribution through traditional channels, as well as over the internet. This paper also analyzes the moderating effect of relationship duration on the influence of the corporate image on trust. Findings - The results obtained show that in distribution through traditional channels no significant differences exist in the intensity of the effect of the image on trust in terms of the relationship duration. Nevertheless, significant differences in the financial services distribution over the internet have been observed. Practical implications - The significant influence that image exerts on consumer trust shows us that corporate image becomes a key tool for the management of trust in financial services distribution. Originality/value - Despite the importance that researchers have assigned to the variables of corporate image and trust, much of the work so far is in the initial phase of development. Thus, the majority of the works have been approached from a fundamentally theoretical perspective, or else the empirical testing has been carried out in an indirect way, based on factors that form part of the image or are related to it. Because of this, today there is no research that has empirically evaluated the role played by corporate image in the levels of trust of the consumer of financial services.

    Notes: Purpose - To analyze empirically the transaction profitability derived from sporadic and frequent customers in the e-retailing sector of minor home appliances in Brazil. Design/methodology/approach - A company's database was analyzed quantitatively to assess the transaction profitability derived from sporadic and frequent customers purchasing via the firm's digital channel, namely its web site. Besides, qualitative evidence was also collected from interviews with the main professionals involved in marketing and e-commerce in the firm and through analysis of the company's web site and e-mail communications with customers. Findings - The commercial transaction profitability associated with sporadic customers can be higher than that derived from frequent purchasers. Research limitations/implications - The study concentrated on a single company within a specific industry (minor home appliance e-retailing) based in a specific country, namely Brazil. Practical implications - The benefits of web consumer retention would only seem to be advantageous for digital companies that are client-centric, which can interact with these consumers. Furthermore, the mere fact of using transactional practices, low differentiation between products and the emphasis on promotion of price on the web would seem to increase sensitivity to price on the part of the consumers, particularly those who make purchases more frequently. Originality/value - To enable practitioners and academics to grasp fully the real value of frequent and sporadic clients, in order to allow digital companies to develop coherent strategies for them.

    Topics: Computer Science
    Notes: Purpose - The web is now a significant component of the recruitment and job search process. However, very little is known about how companies and job seekers use the web, and the ultimate effectiveness of this process. The specific research questions guiding this study are: how do people search for job-related information on the web? How effective are these searches? And how likely are job seekers to find an appropriate job posting or application? Design/methodology/approach - The data used to examine these questions come from job seekers submitting job-related queries to a major web search engine at three points in time over a five-year period. Findings - Results indicate that individuals seeking job information generally submit only one query with several terms and over 45 percent of job-seeking queries contain a specific location reference. Of the documents retrieved, findings suggest that only 52 percent are relevant and only 40 percent of job-specific searches retrieve job postings. Research limitations/implications - This study provides an important contribution to web research and online recruiting literature. The data come from actual web searches, providing a realistic glimpse into how job seekers are actually using the web. Practical implications - The results of this research can assist organizations in seeking to use the web as part of their recruiting efforts, in designing corporate recruiting web sites, and in developing web systems to support job seeking and recruiting. Originality/value - This research is one of the first studies to investigate job searching on the web using longitudinal real world data.

    Web acceptance and usage model: A comparison between goal-directed and experiential web users (2005)

    Topics: Computer Science
    Notes: Purpose - To analyse the web acceptance and usage between goal-directed users and experiential users, incorporating intrinsic motives to improve the particular and explanatory TAM (technology acceptance model) value - traditionally related to extrinsic motives. Design/methodology/approach - A survey instrument was used to gather data to test the relationships shown in the research model. Data were collected from a sample of online questionnaires filled out by subscribers located in three discussion-mailing lists - administered by RedIris - about different topics (e.g. experimental sciences, social sciences and humanities). A structural equation modeling (SEM), specifically partial least squares (PLS), is proposed to assess the relationships between the constructs together with the predictive power of the research model. Findings - The empirical development suggests that there is scope for further extension of TAM to adapt to the web-based usage and its profitable consequences. The article may help to further the empirical research and to clarify and examine a web acceptance and usage model. In general, experiential and goal-directed behaviours moderate the key relationships in the model. Experiential and goal-directed users do not weigh extrinsic and intrinsic motives in the same way when on the web. Goal-directed users are more driven by instrumental factors and focused on their decision-making process while experiential users are more motivated by process.. Research limitations/implications - First, constructs of enjoyment and concentration are used to define flow. However, because of the flow definition's conceptual-vagueness, operationalising the flow construct has been questioned in the previous empirical works. Second, the cross-sectional study is also an important limitation. Since the users' perception and intention can change over time, it is important to measure these quantities at several points of time. Third, the sample sizes are relatively small. Fourth, the model needs to be tested with more objective measures to compare possible divergences. Finally, the model clearly does not include all the relevant variables. Practical implications - The results could be used to explain and to improve the experiential and goal-directed users' experience of being and to return to the web. Originality/value - The value of this study is to reveal the moderating influences of browsing-modes on relationship between flow and TAM-beliefs on the web, and, also, how the flow impacts the attitude and intention to use web between experiential and goal-directed users.

    Notes: Purpose - To contribute to the development of a theoretically grounded measure of organizational internet use (OIU) by conceptualizing and operationalizing it as a theoretical construct, and by empirically assessing its reliability and validity Design/methodology/approach - The focal construct OIU was conceptualized as an abstract collective object with three components, forming an index with formative, causal indicators. A multi-method research design - including a cross-sectional drop-and-collect survey among small technology-based firms (STBFs) in Germany and an observational study of web sites - was applied to assess empirically the theoretically developed construct OIU. This was achieved by using the component-based partial least squares (PLS) structural modeling technique using PLS-Graph. Findings - The empirical assessment of the scale, applied to the international business domain, proved to be reliable and valid in the structural model and across assessment methods. Research limitations/implications - The focal construct was assessed among a very specific population. This limits the claims that can be made with regard to applying it in other industries, countries, and firms. Future research should address this by applying OIU in maximally different research contexts. Practical implications - The developed construct has important implications for both managers and researchers. It should help in assessing levels of organizational internet use in a consistent fashion across populations and studies. It can be used for benchmarking purposes - of specific interest to managers - and it can be used to explore antecedents and consequences of organizational internet use - of specific interest to researchers. Originality/value - Internet research is moving from anecdotal and exuberant internet euphoria to internet pessimism to internet realism. Only theoretically grounded, reliable and valid measures can support such a required transition. With this paper we have made an initial contribution for such a development to occur.

    Notes: Purpose - To identify controls that can harness the power and capabilities of instant messengers (IM) while minimizing potential security risks. Design/methodology/approach - A risk analysis method and (CIS)2 model are used. Findings - IM is a great tool for enterprise productivity. However, it has so many risks, but one could identify and control these risks with technical and managerial countermeasures. Research limitations/implications - This paper fails to provide detailed and specific risks of commercial IMs, and the case study provided in this paper focuses on the technical rather than managerial issues. Practical implications - A very helpful case study which provides general risks and controls of recent IMs for the security officers of various organizations. Originality/value - This paper outlined the risks of IM and potential controls for securing public IM in the workplace.

    Notes: Purpose - Provide a secure solution for web services (WS). A new interoperable and distributed access control for WS is presented. Design/methodology/approach - Based on the separation of the access control (AC) and authorization function. Findings - Mechanisms presented allow seamless integration of external authorization entities in the AC system. The Semantic Policy Language (SPL) developed facilitates specification of policies and semantic policy validation. SPL specifications are modular and can be composed without ambiguity. Also addressed was the problem of the association of policies to resources (WS or their operations) in a dynamic, flexible and automated way. Research limitations/implications - The ACProxy component is currently under development. Ongoing work is focused on achieving a richer "use control" for some types of WS. Practical implications - Administrators of WS can specify AC policies and validate them to find syntactic and semantic errors. Components for automated validation of policies at different levels are included. This ensures that the AC policies produce the desired effects, facilitating the creation and maintenance of policies. It also provides mechanisms for the use of interoperable authorizations. Originality/value - A practical system that provides a secure solution to AC for WS. To the best of one's knowledge, no other system provides mechanisms for semantic validation of policies based on external authorization entities. Likewise, the mechanisms for interoperability of external authorization entities are also novel. The system provides content-based access control and a secure, decentralized and dynamic solution for authorization that facilitates the management of complex systems and enhances the overall security of the AC.

    Notes: Purpose - The increasing number of M-internet subscribers and the fast growing revenue proves the great potential of M-internet as well as the enormous business opportunity in Korea. The success in this business is dependent on understanding the concerns of customers and identifying the factors that promote the use of M-internet. Thus, this paper aims to examine the human motivations underlying individual behavioral intention to use M-internet in Korea. Design/methodology/approach - Employs TAM (technology acceptance model) as the base model and develops a more comprehensive version of TAM to better reflect M-internet context. The model employs perceived playfulness, contents quality, system quality, internet experience and perceived price level, in addition to perceived usefulness and ease of use. Investigates the causal relationships among the constructs used in this revised TAM and identifies the direct and indirect causal role of the constructs in developing the intention to use M-internet. Findings - Finds that attitude toward M-internet is the most significant factor in predicting the behavioral intention to use M-internet. Also identifies the positive role of the perceived playfulness and the negative role of perceived price level in developing the attitude as well as the intention. The positive causal relationships of "perceived contents quality - perceived usefulness", "perceived system quality– perceived usefulness" and "internet experience–perceived ease of use" were also witnessed. Practical implications - Considering the explosive growth of the M-internet market, well-established business strategy in M-internet will deliver great success to the mobile operators. Thus, understanding comprehensive causal relationship among the constructs used in this revised TAM would help managers to better implement the strategic ramifications in promoting M-internet. Originality/value - Develops a more comprehensive version of TAM to better reflect M-internet context in Korea, adding five new constructs and identifies the role of the construct in promoting the use of M-internet.

    Notes: Purpose - This study aims to present a new web page recommendation system that can help users to reduce navigational time on the internet. Design/methodology/approach - The proposed design is based on the primacy effect of browsing behavior, that users prefer top ranking items in search results. This approach is intuitive and requires no training data at all. Findings - A user study showed that users are more satisfied with the proposed search methods than with general search engines using hot keywords. Moreover, two performance measures confirmed that the proposed search methods out-perform other metasearch and search engines. Research limitations/implications - The research has limitations and future work is planned along several directions. First, the search methods implemented are primarily based on the keyword match between the contents of web pages and the user query items. Using the semantic web to recommend concepts and items relevant to the user query might be very helpful in finding the exact contents that users want, particularly when the users do not have enough knowledge about the domains in which they are searching. Second, offering a mechanism that groups search results to improve the way search results are segmented and displayed also assists users to locate the contents they need. Finally, more user feedback is needed to fine-tune the search parameters including a and ß to improve the performance. Practical implications - The proposed model can be used to improve the search performance of any search engine. Originality/value - First, compared with the democratic voting procedure used by metasearch engines, search engine vector voting (SVV) enables a specific combination of search parameters, denoted as a and ß, to be applied to a voted search engine, so that users can either narrow or expand their search results to meet their search preferences. Second, unlike page quality analysis, the hyperlink prediction (HLP) determines qualified pages by simply measuring their user behavior function (UBF) values, and thus takes less computing power. Finally, the advantages of HLP over statistical analysis are that it does not need training data, and it can target both multi-site and site-specific analysis.

    Notes: Purpose - This paper aims to show that information and evidence found in the XML-based environment of web services can allow web services providers to gain a sense of the trustworthiness of web services requestors over time. Design/methodology/approach - A literature review on trust in web services environment is provided. Trust management models, and an existing trust specification for web services are discussed. Next, a conceptual framework for web services trust formation is presented. Findings - The paper makes explicit types of information that can be used for trust formation. Web services providers are given the ability to trust requestors autonomously by making use of information that is published through web services standards, defined over and above a web services interface. The approach incorporates elements of social trust as it is concerned with more than cryptographic controls. It has mechanisms that allow a web services provider to manage trust autonomously, enabling different types of trust for different situations. Research limitations/implications - A conceptual framework for trust formation has been defined that identifies a proposal for trust calculation. The paper does not address the implementation of the framework, and calculation of trust over information categories. Practical implications - The paper identifies a practical approach to autonomous web services trust by making use of web services standards such as WS-Policy and WSMetadataExchange. Originality/value - This paper identifies a taxonomy of trust information that can be used to make explicit the requirements for web services trust.

    Notes: Purpose - The primary purpose was to learn about different variables of an integrated strategy associated with choosing to supply through business-to-business (B2B) intermediaries and apply the variables to a series of cases. Design/methodology/approach - A literature review served as a basis to develop an integrated model. A combination of primary and secondary research was conducted to apply the concepts of the model to different internet trading exchanges. Findings - Each trade exchange offers a different set of customers and suppliers vying for business opportunities. There are no common platforms for software and hardware. If a small company is interested in trading through an internet exchange, they want to select based on the variables identified that best meet their needs and integrate with their business strategy. Research limitations/implications - The focus was on industrial products and may not be applicable to consumer products. Practical implications - Suppliers must carefully operate in the future by evaluating each customer and determining which trade exchanges will provide them with the greatest benefit at the lowest cost. The infrastructure investment is an unavoidable cost that cannot be forgone unless the supplier wants to discontinue providing to most of its customers. The supplier needs to look at all aspects identified in the integrated business model and the foundation and facilitation for success lie in the information management of the entire entity. Originality/value - This paper takes the existing body of knowledge and applies it to the development of an integrated e-business model for industrial suppliers used to compare different internet trading exchanges.

    Notes: Purpose - The purpose of this paper is to provide a framework for enhancing security policy management in the Grid. Design/methodology/approach - The Grid security policy reconciliation problem is presented. A generic view on the security policy notion is adopted and the security policy ontology notion is introduced and used. Findings - In the course of this work it was found that, in order to enhance security policy management in the Grid, Grid entities should have the ability to negotiate their security policies. It was also found that, in order to achieve security policy negotiation, effective security policy semantics manipulation towards security policy reconciliation is needed. Finally, it was established, through the use of an example, that if appropriate means are used for security policy reconciliation then incompatible security policy representations can be transformed into compatible ones. Research limitations/implications - Research limitations stem from the adoption of a generic view on the security policy notion and the selection of identification and authentication security policies as the focal point of the proposed framework. Research implications include the possibility of examining how existing security policy reconciliation models can be incorporated in this generic framework. The possibility of investigating how such a framework can lead to a security policy knowledge management tool for Grid administrators is also demonstrated. Practical implications - Practical implications of this work include the establishment of a common framework for security information exchange between Grid entities. Originality/value - This paper proposes a framework for enhancing security policy management in the Grid. The proposed framework can be used by researchers as a reference and by security experts in order to reduce ambiguity concerning the interpretation of security policies expressed in different forms, by negotiating Grid entities.

    Notes: Purpose - To carry out a practical experiment into the feasibility of service orientation to achieve a dynamic, late-binding service architecture. Design/methodology/approach - Literature view to provide a foundation in standards and measure anecdotal opinion regarding service orientation. The review informed an architectural design based on real world requirements from a multinational mobile telecommunications organisation moving toward portal-based services. The architectural implementation took place in a lab-based setting and tested with third-party services that were integrated into the architecture dynamically to test the late bound requirements of the infrastructure. The experimental approach also enabled the testing of the opinions formed regarding service orientation. Findings - The main outcome of the study related to the open, standards-based nature purported to be possible with service orientation. The findings on the study highlighted some major problems in interoperability and operational efficiency of service-oriented technologies when applied to a complex architecture framework. Research limitations/implications - Currently this represents the findings of a single study based on a specific set of requirements. In order to generalise, further study is needed and currently ongoing. Practical implications - The study has high implications for people wishing to approach service orientation as a means to integrate both new and legacy systems. The work raises a lot of questions about the supposed ease of integration. Originality/value - The work contributes to a growing body of work examining and evaluating the usefulness of service orientation.

    Towards improved labour standards for construction of minor works in low income countries (2005)
    Oxford : Emerald
    Engineering, construction and architectural management 12 (2005), S. 617-632 
    Details
    ISSN: 1365-232X

    Topics: Architecture, Civil Engineering, Surveying
    Notes: Purpose - The construction industry is one of the largest employment providers in the developing world. It is also one of the least safe industries, with a high frequency of accidents resulting in financial losses, injuries, disabilities and deaths. Decent working conditions and resulting improved worker satisfaction are key to sustainable productivity in the industry. International standards safeguarding construction workers are abundant and ratified by most low-income countries. This paper aims to examine if these standards are adequately reflected in contracts for construction works; and if they not, how contract clauses can be improved and put into operation. Design/methodology/approach - Based on research undertaken in Ghana, India and Zambia from 2000 to 2003, this paper explores the aforementioned points. The paper comprises analysis of contract clauses from the International Federation of Consulting Engineers (FIDIC) and developing country contracts, along with case study findings. Findings - This paper finds that more legislation is not the urgent issue; incorporating existing legislation into construction contracts and making clauses operational is a priority. This paper identifies practical and cost-effective procedures for bringing stakeholders together to implement and monitor labour standards, with the aim of contributing to the overall goal of providing "decent work" for all workers in the construction industry. Originality/value - This paper explores issues around implementing labour standards in construction of minor infrastructure works in low income countries and concludes with suggestions on how best to put contract clauses into operation through a process approach.

    Notes: Purpose - To present a model of innovative change in higher education based on research into the factors behind the performance of highly creative historical communities. Design/methodology/approach - The article diagnoses current pressures under which academia is laboring, explains the hothouse effect, and proposes solutions based on the hothouse effect model. Findings - The article proposes restructuring of discipline-based learning, developing new methods of strategic planning, adopting new assumptions about the social role of higher education, exploring modes of perception and cognition that are critical to education, and using digital technology to create learning communities and facilitate accelerated learning models. The model of organizational change emphasizes modest and numerous grass-roots initiatives as the most efficient generator of broad cultural change. Research limitations/implications - The aim is to stimulate pilot initiatives and broad dialog on the issues raised. The research points the way to further work in the dynamics of creativity, the nature of pedagogy, and the future role of the university. Practical implications - Numerous methods are presented for strengthening the relationship of faculty and administration, utilizing technology to create learning communities and transform pedagogy, stimulating faculty collaboration, and planning for the future. Originality/value - This paper provides many fresh and practical ideas useful at an individual, department, or institutional level. The goal is not a specific type of institution or mode of operation. Instead, it the model is flexible and adaptable to creative initiatives of any scope. Ultimately, this article can contribute to revitalizing the ongoing dialog about higher education's future.

    Notes: Purpose - To ascertain how scholarship will be impacted by digital media. Design/methodology/approach - This paper breaks down the vocation of scholarship into subsidiary tasks. It examines how their relative importance has changed in the modern era. Finally, it looks at which tasks will be facilitated or complicated by digital media, particularly by the internet. Findings - The tasks of collecting and storing information have been made far faster and easier by digital media. Other tasks such as sorting, evaluating and assessing the implications of information have, however, become more difficult. In consequence, theory has become far more important. Research limitations/implications - The extrapolations in this paper are about broad trends, which may manifest themselves in a variety of ways. Practical implications - In the future, one can expect scholarship to deal less with uncovering new information. Instead, scholars will have to devote more time and effort to ascertaining why information is important. Scholars will be expected to articulate not only their methods but also their purposes. Originality/value - This paper provides useful information on how scholarship will be impacted by digital media.

    Notes: Purpose - To analyze the extent of, and the reasons for, institutional change in the private corporation. Design/methodology/approach - The paper identifies seven "new rules of corporate conduct" which, in total, represent a radical change in the social contract between society and the corporation. It then speculates about future changes in corporate purpose and governance. Findings - A central feature of the new corporate charter is that it is likely to entail a redefinition of the relationship between profit and corporate purpose. The purpose is service to society (i.e. serving social needs), while profit provides the means, motive and measure. Originality/value - This paper provides the basis and rationale for moving the corporation from "profit-as-purpose" to "service-as-purpose" as the organizing principle for its strategies, values and actions.

    Notes: Purpose - To examine and discuss the central features of institutional change and to compare it with organizational change. Design/methodology/approach - Use interviews with managers to highlight key issues. Findings - Results are presented of interviews with managers exploring changes that have for decades been transforming business, government, and other institutions into "organic" systems for the knowledge age. Institutional change differs from organizational change by focusing on the higher-order unspoken social rules that govern the structure of institutions in common. The study evaluated trends driving this transformation, the obstacles blocking it, and the likely timetable of implementation. Originality/value - Concludes that three central features mark the general direction of institutional evolution: "e-organizations" operating in real time, "self-organizing systems" of self-managed teams, and "stakeholder collaboration" to unify diverse interests into a more powerful enterprise.

    Notes: Purpose - Highlight the management dilemma disruptive innovation poses and examine what the leading management theorists have to offer as a solution. Design/methodology/approach - The author examines six leading theories of innovation and three alternatives to disruptive innovation. Findings - The leading theories that try to solve the paradox of innovation don't work and the alternatives to disruptive innovation merely delay having to deal with the dilemma. Research limitations/implications - The author reviewed many theoretical approaches to innovation management and selected six for commentary. Practical implications - The author argues that the theorists are looking at innovation in the wrong way. Because innovation is a paradox, the solution lies in rethinking the fundamental assumptions. Originality/value - First article that examines the logic behind the leading disruptive innovation theories and refutes their advice.

    Notes: Purpose - To encourage top management to recognize the need for adding new value to their organizations and commit to the creation of new internal capabilities for growth via the exploration of their company's strategic frontier. Design/methodology/approach - Explains how the CEO can select a team and initiate a project to identify strategy frontier options. Findings - The authors' experience suggests that the team should first explore all areas of future growth potential in and adjacent to their industry, creating a long list of potential options. Identifying a breadth of strategic frontier options is more important than a depth of information on any one option. Research limitations/implications - More case studies of strategy frontier projects in action, with quantitative results, would be valuable. Practical implications - The goal of this frontier team is to identify a portfolio of innovative new business opportunities that exist on the strategic frontier. It will be the responsibility of another, more qualified group with quantitative skills (strategic planners, business development) to develop a detailed business design and determine its profitability and attractiveness to the company. Originality/value - The article offers top management an innovative how-to approach to finding truly new growth opportunities.

    Notes: Purpose - Managers need research-based guidance on how to find sources of new growth when their core business is maturing. Design/methodology/approach - Authors shadowed managers responsible for finding and entering new businesses, interviewing them every three or four months for an average of two years. They surveyed over 100 corporate venturing units and corporate incubators and assembled a database of over 50 stories of companies that had successfully developed or acquired a significant new business. We interviewed managers in about half of these companies that had successfully diversified and we tested our emerging hypotheses against this database. Findings - All research indicated that managers need to assess opportunities more strategically and be less activity driven. The authors concluded that managers were investing in too many projects, most of which had little chance of success. Research limitations/implications - If research is reported on in the paper this section must be completed and should include suggestions for future research and any identified limitations in the research process. Practical implications - Ashridge Strategic Management Centre has developed a screening tool - The New Businesses Traffic Lights to test opportunities before a business plan has been developed, alongside a business plan to assess the strategic logic for the proposal, or to an existing investment that is failing to meet its short-term targets. Originality/value - Applying the screen to the portfolio of new business investments in most companies will result in red lights for many projects. Not only can significant money be saved from the "new businesses" budget, but also extra resources can be focused on improving the core businesses.

    Notes: Purpose - During the past year, the authors have built a framework for a suite of metrics that senior managers can customize to track and promote innovation success in their companies. Design/methodology/approach - Senior executives can use the suite of metrics to assess their company's innovativeness over time and hence combat the insidious strategy decay that often afflicts a company's business. Findings - The framework combines three views on innovation - resource, capability, and leadership - providing the perspective to develop a suite of metrics for assessing and developing a company's capacity for innovation. Research limitations/implications - The optimal selection of metrics and the optimal value or "sweet spot" of any particular metric will vary from company to company. Practical implications - As more firms develop strategic innovation metrics and a database that validates their relevance, top managers will learn to assess and guide a company's innovation capability more effectively. Originality/value - This is the first strategic guideline for building a customizable system of innovation metrics.

    Topics: Economics
    Notes: Purpose - This study proposes investigating the branding of small to medium-sized enterprise (SME) wineries in an Australian context. By taking a qualitative approach, the theory building research seeks further to understand branding from the perspective of the SME winery, and in doing so, go some way in addressing the current deficit in the literature. Design/methodology/approach - Bhat and Reddy's conceptualisation of brand functionality and symbolism is used as a branding framework to underlie the research. A multiple case study design was adopted as a research method to provide case data on eight SME wineries. Data were collected through in-depth interviews with the owner/manager of each winery, direct observation and document analysis. Findings - The findings are presented in the form a model of SME winery branding, which, in addition to distinguishing two approaches to branding, highlights the functional and symbolic values inherent in the brand. The findings endorse the notion that brands can simultaneously have both functional and symbolic appeal. More radically, the emergent model suggests interdependence between the functional and symbolic properties of branding. Practical implications - Practically, the findings highlight the importance of developing the symbolic values associated with the brand, which represent a more sustainable competitive advantage. Originality/value - By establishing a tentative theory on SME winery branding, this study has begun to address the current deficit in wine marketing literature and has set a foundation for further research.
