    Description: Enterocytozoon bieneusi is the most common microsporidian associated with human disease, particularly in the immunocompromised population. In the setting of HIV infection, it is associated with diarrhea and wasting syndrome. Like all microsporidia, E. bieneusi is an obligate, intracellular parasite, but unlike others, it is in direct contact with the host cell cytoplasm. Studies of E. bieneusi have been greatly limited due to the absence of genomic data and lack of a robust cultivation system. Here, we present the first large-scale genomic dataset for E. bieneusi. Approximately 3.86 Mb of unique sequence was generated by paired end Sanger sequencing, representing about 64% of the estimated 6 Mb genome. A total of 3,804 genes were identified in E. bieneusi, of which 1,702 encode proteins with assigned functions. Of these, 653 are homologs of Encephalitozoon cuniculi proteins. Only one E. bieneusi protein with assigned function had no E. cuniculi homolog. The shared proteins were, in general, evenly distributed among the functional categories, with the exception of a dearth of genes encoding proteins associated with pathways for fatty acid and core carbon metabolism. Short intergenic regions, high gene density, and shortened protein-coding sequences were observed in the E. bieneusi genome, all traits consistent with genomic compaction. Our findings suggest that E. bieneusi is a likely model for extreme genome reduction and host dependence.

    Description: The intestinal microbiota is essential to human health, with effects on nutrition, metabolism, pathogen resistance, and other processes. Antibiotics may disrupt these interactions and cause acute disease, as well as contribute to chronic health problems, although technical challenges have hampered research on this front. Several recent studies have characterized uncultured and complex microbial communities by applying a new, massively parallel technology to obtain hundreds of thousands of sequences of a specific variable region within the small subunit rRNA gene. These shorter sequences provide an indication of diversity. We used this technique to track changes in the intestinal microbiota of three healthy humans before and after treatment with the antibiotic ciprofloxacin, with high sensitivity and resolution, and without sacrificing breadth of coverage. Consistent with previous results, we found that the microbiota of these individuals was similar at the genus level, but interindividual differences were evident at finer scales. Ciprofloxacin reduced the diversity of the intestinal microbiota, with significant effects on about one-third of the bacterial taxa. Despite this pervasive disturbance, the membership of the communities had largely returned to the pretreatment state within 4 weeks.

    Exploring microbial diversity and taxonomy using SSU rRNA hypervariable tag sequencing (2009)
    Public Library of Science
    Details
    Publication Date: 2022-05-25
    Description: © 2008 Huse et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License. The definitive version was published in PLoS Genetics 4 (2008): e1000255, doi:10.1371/journal.pgen.1000255.
    Description: Massively parallel pyrosequencing of hypervariable regions from small subunit ribosomal RNA (SSU rRNA) genes can sample a microbial community two or three orders of magnitude more deeply per dollar and per hour than capillary sequencing of full-length SSU rRNA. As with full-length rRNA surveys, each sequence read is a tag surrogate for a single microbe. However, rather than assigning taxonomy by creating gene trees de novo that include all experimental sequences and certain reference taxa, we compare the hypervariable region tags to an extensive database of rRNA sequences and assign taxonomy based on the best match in a Global Alignment for Sequence Taxonomy (GAST) process. The resulting taxonomic census provides information on both composition and diversity of the microbial community. To determine the effectiveness of using only hypervariable region tags for assessing microbial community membership, we compared the taxonomy assigned to the V3 and V6 hypervariable regions with the taxonomy assigned to full-length SSU rRNA sequences isolated from both the human gut and a deep-sea hydrothermal vent. The hypervariable region tags and full-length rRNA sequences provided equivalent taxonomy and measures of relative abundance of microbial communities, even for tags up to 15% divergent from their nearest reference match. The greater sampling depth per dollar afforded by massively parallel pyrosequencing reveals many more members of the “rare biosphere” than does capillary sequencing of the full-length gene. In addition, tag sequencing eliminates cloning bias and the sequences are short enough to be completely sequenced in a single read, maximizing the number of organisms sampled in a run while minimizing chimera formation. This technique allows the cost-effective exploration of changes in microbial community structure, including the rare biosphere, over space and time and can be applied immediately to initiatives, such as the Human Microbiome Project.

    A new family of giardial cysteine-rich non-VSP protein genes and a novel cyst protein (2007)

    Description: Since the Giardia lamblia cyst wall is necessary for survival in the environment and host infection, we tested the hypothesis that it contains proteins other than the three known cyst wall proteins. Serial analysis of gene expression during growth and encystation revealed a gene, “HCNCp” (High Cysteine Non-variant Cyst protein), that was upregulated late in encystation, and that resembled the classic Giardia variable surface proteins (VSPs) that cover the trophozoite plasmalemma. HCNCp is 13.9% cysteine, with many “CxxC” tetrapeptide motifs and a transmembrane sequence near the C-terminus. However, HCNCp has multiple “CxC” motifs rarely found in VSPs, and does not localize to the trophozoite plasmalemma. Moreover, the HCNCp C-terminus differed from the canonical VSP signature. Full-length epitope-tagged HCNCp expressed under its own promoter was upregulated during encystation with highest expression in cysts, including 42 and 21 kDa C-terminal fragments. Tagged HCNCp targeted to the nuclear envelope in trophozoites, and co-localized with cyst proteins to encystation-specific secretory vesicles during encystation. HCNCp defined a novel trafficking pathway as it localized to the wall and body of cysts, while the cyst proteins were exclusively in the wall. Unlike VSPs, HCNCp is expressed in at least five giardial strains and four WB subclones expressing different VSPs. Bioinformatics identified 60 additional large high cysteine membrane proteins (HCMp) containing ≥20 CxxC/CxC's lacking the VSP-specific C-terminal CRGKA. HCMp were absent or rare in other model or parasite genomes, except for Tetrahymena thermophila with 30. MEME analysis classified the 61 gHCMp genes into nine groups with similar internal motifs. Our data suggest that HCNCp is a novel invariant cyst protein belonging to a new HCMp family that is abundant in the Giardia genome. HCNCp and the other HCMp provide a rich source for developing parasite-specific diagnostic reagents, vaccine candidates, and subjects for further research into Giardia biology.

    Power efficiency of outer hair cell somatic electromotility (2009)

    Description: Cochlear outer hair cells (OHCs) are fast biological motors that serve to enhance the vibration of the organ of Corti and increase the sensitivity of the inner ear to sound. Exactly how OHCs produce useful mechanical power at auditory frequencies, given their intrinsic biophysical properties, has been a subject of considerable debate. To address this we formulated a mathematical model of the OHC based on first principles and analyzed the power conversion efficiency in the frequency domain. The model includes a mixture-composite constitutive model of the active lateral wall and spatially distributed electro-mechanical fields. The analysis predicts that: 1) the peak power efficiency is likely to be tuned to a specific frequency, dependent upon OHC length, and this tuning may contribute to the place principle and frequency selectivity in the cochlea; 2) the OHC power output can be detuned and attenuated by increasing the basal conductance of the cell, a parameter likely controlled by the brain via the efferent system; and 3) power output efficiency is limited by mechanical properties of the load, thus suggesting that impedance of the organ of Corti may be matched regionally to the OHC. The high power efficiency, tuning, and efferent control of outer hair cells are the direct result of biophysical properties of the cells, thus providing the physical basis for the remarkable sensitivity and selectivity of hearing.

    The origin and initial rise of pelagic cephalopods in the Ordovician (2009)
    Public Library of Science
    In:  PLoS ONE, 4 (9). e7262.
    Details
    Publication Date: 2021-08-26
    Description: Background During the Ordovician the global diversity increased dramatically at family, genus and species levels. Partially the diversification is explained by an increased nutrient, and phytoplankton availability in the open water. Cephalopods are among the top predators of todays open oceans. Their Ordovician occurrences, diversity evolution and abundance pattern potentially provides information on the evolution of the pelagic food chain. Methodology/Principal Findings We reconstructed the cephalopod departure from originally exclusively neritic habitats into the pelagic zone by the compilation of occurrence data in offshore paleoenvironments from the Paleobiology Database, and from own data, by evidence of the functional morphology, and the taphonomy of selected cephalopod faunas. The occurrence data show, that cephalopod associations in offshore depositional settings and black shales are characterized by a specific composition, often dominated by orthocerids and lituitids. The siphuncle and conch form of these cephalopods indicate a dominant lifestyle as pelagic, vertical migrants. The frequency distribution of conch sizes and the pattern of epibionts indicate an autochthonous origin of the majority of orthocerid and lituitid shells. The consistent concentration of these cephalopods in deep subtidal sediments, starting from the middle Tremadocian indicates the occupation of the pelagic zone early in the Early Ordovician and a subsequent diversification which peaked during the Darriwilian. Conclusions/Significance The exploitation of the pelagic realm started synchronously in several independent invertebrate clades during the latest Cambrian to Middle Ordovician. The initial rise and diversification of pelagic cephalopods during the Early and Middle Ordovician indicates the establishment of a pelagic food chain sustainable enough for the development of a diverse fauna of large predators. The earliest pelagic cephalopods were slowly swimming vertical migrants. The appearance and early diversification of pelagic cephalopods is interpreted as a consequence of the increased food availability in the open water since the latest Cambrian.

    The Genome of Deep-Sea Vent Chemolithoautotroph Thiomicrospira crunogena XCL-2 (2006)
    Public Library of Science
    In:  PLOS Biology, 4 (12). e383.
    Details
    Publication Date: 2020-06-15
    Description: Presented here is the complete genome sequence of Thiomicrospira crunogena XCL-2, representative of ubiquitous chemolithoautotrophic sulfur-oxidizing bacteria isolated from deep-sea hydrothermal vents. This gammaproteobacterium has a single chromosome (2,427,734 base pairs), and its genome illustrates many of the adaptations that have enabled it to thrive at vents globally. It has 14 methyl-accepting chemotaxis protein genes, including four that may assist in positioning it in the redoxcline. A relative abundance of coding sequences (CDSs) encoding regulatory proteins likely control the expression of genes encoding carboxysomes, multiple dissolved inorganic nitrogen and phosphate transporters, as well as a phosphonate operon, which provide this species with a variety of options for acquiring these substrates from the environment. Thiom. crunogena XCL-2 is unusual among obligate sulfur-oxidizing bacteria in relying on the Sox system for the oxidation of reduced sulfur compounds. The genome has characteristics consistent with an obligately chemolithoautotrophic lifestyle, including few transporters predicted to have organic allocrits, and Calvin-Benson-Bassham cycle CDSs scattered throughout the genome.

    Evidence of seismic deformation of the paved floor of the decumanus at Tindari (NE, Sicily) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: Most of the ancient town of Tindari (NE, Sicily) was settled on a plateau the most surficial layer of which was made of unconsolidated material. Ongoing excavations at the archaeological site at Tindari uncovered a large portion of the decumanus which suffered deformations preliminarily assigned to coseismic effects. An analysis of the local dynamic response through the simulation of strong seismic shaking to the bedrock and modelling of spectral ratios of the bedrock-soft soil was carried out to verify the susceptibility of superficial terrains of the promontory to coseismic deformations. To perform this simulation the finite element method (FEM) was used. Four accelerometric recordings of three earthquakes of medium-high magnitude, recorded on rocky sites, were chosen to simulate the seismic shaking, using a constitutive law for the materials composing the promontory layers both of linear-elastic type and of elastoplastic type. The analysis of the linear-elastic field allowed the definition of the frequencies for which the spectral ratios of the accelerations recorded the highest amplifications; in particular the frequency range 31.5–37.2 Hz can be combined with deformation of the paved floor of the decumanus. The analysis in the elastoplastic field highlighted the zones of promontory more susceptible to suffer plasticization process. The results show that the topmost layer of the decumanus is the most susceptible to suffer plasticization. Therefore, the performed analysis lends greater support to the hypothesis that the deformations were produced by seismic shaking.

    Tectonic features of the Lipari–Vulcano complex (Aeolian archipelago, Italy) from 10 years (1996–2006) of GPS data (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: The tectonic deformation of the Lipari-Vulcano complex, one of the most important active volcanic areas of Mediterranean region, is studied here through the analysis of ten years (1996-2006) of GPS data from both 3 permanent and 13 non-permanent stations. This area can be considered crucial for the understanding of the Eurasia-Africa plates interaction in the Mediterranean area, and, in general, this work emphasize a methodological approach, already applied in other areas worldwide (e.g. Shen et al., 1996, El-Fiki and Kato, 1999) where geodetic data and strain parameters maps of critical areas can help to improve our understanding of their geodynamical aspects. In this framework, this study is aimed at providing a kinematic deformation model on the basis of the dense geodetically estimated velocities of the Lipari-Vulcano complex. In particular, the observed deformation pattern can be described by a mix between 1) the main N-S regional compression and 2) a NNE-SSW compression with a small right-lateral strike slip component acting along a tectonic structure N°40W trending located between the two islands. This pattern was inspected through a simplified synthetic model.

    New results of 40Ar/39Ar dating constrain the timing of transition from fissure-type to central volcanism at Mount Etna (Italy) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: Recent geological studies performed at Etna allow reassessing the stratigraphic frame of the volcano where distinct evolutionary phases are defined. This stratigraphic reconstruction was chronologically constrained on the basis of a limited number of U–Th and K–Ar age determinations whose uncertainty margins are sometimes too wide. For this reason, we successfully adopted at Etna the 40Ar/39Ar technique that allowed obtaining more precise age determinations. The incremental heating technique also gives information on sample homogeneity, and potential problems of trapped argon. Five samples were collected from stratigraphically well-controlled volcanic units in order to chronologically define the transition between the fissure-type volcanism of the Timpe phase to the central volcanism of the Valle del Bove Centers. Isotopic ages with an uncertainty margin of 2–4% have been obtained emphasizing that this transition occurred (130– 126 ka) without significant temporal hiatus.

    Methane seepage in an urban development area (Bacau, Romania): origin, extent, and hazard (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: The paper describes a case of a natural emission of methane from soil in an urban development area, generating a significant risk for the local population and buildings, due to gas explosiveness and asphyxiation potential. The site is located on the south-western margin of the East-European Platform in eastern Romania, in a hydrocarbon-prone area crossed by the Pericarpathian lineament and regional faults. Molecular composition of gas and stable isotopic analyses of methane (CH4〉90%, δ to the power of 13 C1: -49.4‰, δD1: -173.4‰) indicate a dominant thermogenic origin, with significant amounts of C2-C5 alkanes (~5%), likely migrating through faults from a deep reservoir. Possible candidates are the Saucesti and Secuieni gas fields, located in the same petroleum system. Two surface geochemical surveys, based on closed-chamber flux measurements, were performed to assess the degassing intensity and the extent of the affected area. Methane fluxes from soil reach orders of 10 to the power of 4 mg m to the power of -2 day to the power of -1. Gas seepage mainly occurs in one zone 30 000 m2 wide, and it is likely controlled by channeling along a fault and gas accumulation in permeable sediments and shallow subsoil. The estimated total CH4 emission is about 40 t year to the power of -1 CH4, of which 8–9 t year to the power of -1 are naturally released from soil and 30–35 t year to the power of -1 are emitted from shallow boreholes. These wells have likely channeled the gas accumulated in shallow alluvial sediment but gas flux from soil is still high and mitigation measures are needed to reduce the risk for humans and buildings.

    New evidence for a mixed inorganic and organic origin of the Olympic Chimaera fire (Turkey): a large onshore seepage of abiogenic gas (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: The Chimaera gas seep, near Antalya (SW Turkey), has been continuously active for thousands of years and it is known to be the source of the first Olympic fire in the Hellenistic period. New and thorough molecular and isotopic analyses including methane (approximately 87% v/v; δ to the power of 13 C1 from -7.9‰ to -12.3‰; δ to the power of 13 D1 from -119‰ to -124‰), light alkanes (C2 + C3 + C4 + C5 = 0.5%; C6+: 0.07%; δ to the power of 13 C2 from -24.2‰ to -26.5‰; δ to the power of 13 C3 from -25.5‰ to -27‰), hydrogen (7.5–11%), carbon dioxide (0.01–0.07%; δ to the power of 13 CCO2: -15‰), helium (approximately 80 ppmv; R/Ra: 0.41) and nitrogen (2–4.9%; δ to the power of 15 N from -2‰ to -2.8‰) converge to indicate that the seep releases a mixture of organic thermogenic gas, related to mature type III kerogen occurring in Palaeozoic and Mesozoic organic-rich sedimentary rocks, and abiogenic gas produced by low-temperature serpentinization in the Tekirova ophiolitic unit. Methane is not related to mantle or magma degassing. The abiogenic fraction accounts for about half of the total gas released, which is estimated to be well beyond 50 ton year to the power of -1. Ophiolites and limestones are in contact along a tectonic dislocation leading to gas mixing and migration to the Earth’s surface. Chimaera represents the biggest emission of abiogenic methane on land discovered so far. Deep and pressurized gas accumulations are necessary to sustain the Chimaera gas flow for thousands of years and are likely to have been charged by an active inorganic source.

    Multiple hydro-fracturing by boron-rich fluids in the Late Miocene contact aureole of eastern Elba Island (Tuscany, Italy) (2008)
    Blackwell Publishing Ltd
    Details
    Publication Date: 2017-04-04
    Description: In eastern Elba Island (Tuscany, Italy), a shallow crustal level felsic, tourmaline-bearing, dyke-sill swarm of Late Miocene age is associated with abundant tourmaline-quartz hydrothermal veins and metasomatic masses. Development of these veins and masses in the host rocks demonstrates multiple hydro-fracturing by magmatic, boron-rich saline fluid. Tourmalines in felsic dykes are schorl, whereas in veins and metasomatic masses, tourmaline composition ranges from schorl-dravite through dravite to uvite. This compositional shift is evidence for an increasing contribution to the magmatic boron-rich fluids by a Mg-Ca-Ti-rich external component represented by biotite-rich and amphibolite host rocks. This system can be envisaged as an exposed proxy of the high temperature hydrothermal system presently active in the deepest part of the Larderello-Travale geothermal field (Tuscany).

    Notes: High-performing project teams are crucial for effective research and development (R&D). To become high performing, teams need to make use of their different skills and reflect upon their collective actions, thereby combining knowledge that could lead to value-adding activities for the company. This article describes the use of team coaching in supporting team reflection and learning in global R&D project teams. A collaborative research approach was used during the 8 months of coaching, with several inquiry methods being employed. The results indicate that coaching interventions have a positive effect on team performance, both from an efficiency perspective as well as from a creativity and climate perspective. Practical and theoretical implications are discussed, as is future research.

    Notes: One crucial yet relatively unexamined perspective on issues of concern to both organizations and nations, the creativity and productivity of scientific efforts, is the insider perspective. Insiders are privy to confidential information – in this study, first-hand observations of good and bad leadership – because of their position within the laboratory. The insider perspective can help answer such questions as: What are scientists' lived experiences of effective management? What have they observed as some of the impacts of ineffective management? What worries them in terms of their own capacity to lead and manage? This paper describes interim results of an ongoing, exploratory study of insiders in academia, government, and industry. For the past 5 years, more than 200 scientific researchers from Europe, Asia, and the US have been asked open-ended questions about (1) the best example of scientific leadership they have encountered; (2) the worst example; and (3) their most difficult problems leading scientific endeavours. Their responses to date have included unexpected and surprising results. Good leaders are most frequently described as caring and compassionate (in contrast to the expected description of technically competent). Bad leaders are most frequently described as (surprisingly) abusive. The other important (and ‘unintended’) finding is that gender inequity persists. These responses illuminate some of the challenges facing those who manage research and development (R&D), who study the management of R&D, and who are responsible for national policies regarding R&D.

    Mentoring and organisational learning in research and development (2005)

    Notes: This paper presents and discusses the contribution of ‘mentoring’ relationships to organisational learning and knowledge creation in the early stages of research and development (R&D) projects. Our study considers the characteristics of a scientific leader, the nature of the context he creates, and how dialogue contributes to scientific breakthrough. Our study is unusual in as much as research on knowledge creation has developed separately, yet in parallel, with that of mentoring. It is rare to combine these disciplines and yet our research shows there is much to learn from examining the two as a process.We conducted our research at TECHNO, a high-tech-based European company producing advanced equipment dedicated to particles acceleration. Interviews were carried out in 2002–2003 with the founder of the company, the head of the R&D and engineering department, and team members involved in the low energy cyclotron project.Our exploratory research enabled us to identify differences in actors' perceptions about the nature and characteristics of these relationships. Our study also suggests that not all sets of relationships can tolerate the degree of intensity provided by the ‘mentor’. TECHNO has other ‘mentors’ who do not manage to generate the same creative context. Complementary mentoring styles based on premises and process reflection allow to support and enhance ‘upper levels’ learning by junior team members. We examine the nature of the leaders as mentors and catalysts within the learning process and briefly discuss implications for setting up and maintaining learning teams.

    Notes: The present research uses conversations with new product innovators in commercial organisations to explore how they experience innovating in those organisations. Based on their words, the study explores how innovators experience the complex social settings and structures of their organisation, how this affects creativity, and how innovative climates are enabled or inhibited by it. Organic, self-organising working structures are shown to enable creative commercial innovation more easily than hierarchical settings. Innovators' own words also identify what motivates them. ‘Excitement’ and ‘creative buzz’ are shown to be common intrinsic motivators and ‘tangible benefit’ for organisation or customers is shown to reinforce this. Innovators' experience of networks is also studied, along with their experiences of leadership in organisations. While this study is exploratory in scope, it is hoped that it will be of value in organisations looking to build effective partnerships with their innovators.

    Common purpose and divided loyalties: the risks and rewards of cross-sector collaboration for academic and government researchers (2005)

    Notes: International evidence shows that research is increasingly being carried out in organisational forms built around cross-sectoral (government, academic and business) and transdisciplinary teams with well-defined national social, economic or environmental objectives in view. As a result, new and unfamiliar forms of organisational arrangements for research are emerging within universities and elsewhere. These collaborative research centres have been variously termed ‘hybrid’ or ‘parasitic’. This paper draws upon around 30 in-depth interviews with participants from selected Australian Cooperative Research Centres (CRC). It examines how researchers reconcile the many demands of their dual role, first, as a government researcher or academic, and second as a committed participant in an industry-collaborative research centre. These collaborations go beyond ‘applied research’ to span fundamental research and immediately useful knowledge. But reward systems and performance measures for academic researchers are still founded largely on ‘discovery’, while those for government researchers are based upon ‘application’. The risk is that researchers will be deflected by the collaboration in ways that conflict with their institutional responsibilities. The paper reports work analysing the management strategies used by the CRCs and their public sector partners to ensure that their common goals are achieved while preserving their institutional interests and the expectations of their research staff. The aim is to identify effective ways of managing the various ‘risks’ of cross-sector collaborative research and development (R&D) in Australia and more widely.

    Investigating differences among research projects and implications for managers (2005)

    Notes: As research and innovation have become central to the economy, the challenge of managing these activities has taken on greater importance. Studies have focused on the impact of organizational variables on research activities, such as work environment, human resource factors, and managerial practices. But little attention has been paid to the effect of differences among types of research projects. While the notion that differences exist among research projects is acknowledged, particularly in the research & development portfolio literature, there have been relatively few studies into the dimensions by which research projects, and needs of project team members, differ. Further, there is little recognition that these differences translate into the need for different research project management practices. The objective of this paper is to investigate differences among research projects along three dimensions, amount of funding, complexity of project teams, and research orientation. These dimensions are selected because of their central theoretical importance in the organizational literature, as well as posing a number of different challenges for research management. This study looked at 18 research projects at a national laboratory and analyzed the responses of project members to a comprehensive research environment survey conducted in 2001. The results of the analysis indicate that there are significant differences between types of projects along three dimensions and suggest ways that research performance can be improved through management intervention.

    Patent-based inventor profiles as a basis for human resource decisions in research and development (2005)

    Notes: Profiles of inventors' technological competence are a valuable source of information for decision-making in research and development (R&D) management, e.g. concerning inventor assessment, human resource development and R&D team-building. In the following exposition, a new method of inventor profiling will be put forward, which is based in particular on semantic patent analysis and multidimensional scaling. First, in the course of semantic patent analysis, specialized software, equipped with a natural language processor, reads the patent text transferring the contents into a subject–action–object–format (SAO). The extracted SAO structures are then used to create similarity matrices for patents or patent sets, respectively, according to a specific similarity value. Subsequently, an inventor competence map can be produced by means of multidimensional scaling.The benefits of this method for R&D-related issues in human resource management will be illustrated by the example of a German mechanical engineering company. Two distinct types of profiles were generated and tested: (i) the profile of a single key inventor and (ii) a profile of key inventor sets. The single key inventor profile gives information on the range of competence, i.e. the homogeneity or heterogeneity of a certain inventor's competences, providing far more detailed insights than resorting to bibliographic data like international patent classification (IPC) classes or citations, whereas the latter kind of profile establishes the position of a certain key inventor in relation to others, helping to highlight specific groups of inventors and their domains. These results are clearly apt to support human resource management.

    Notes: This article reports on the union recognition dispute that took place at the McDonald's food-processing plant in Moscow. It examines this dispute in the context of McDonald's employment practices worldwide, the interventions made by international and local unions, and Russian government bodies. Despite these interventions it became impossible to either organise the workforce or establish a collective agreement. The case illustrates the difficulties facing both local unions and global union federations when confronted by intransigent multinational companies, especially in low-skilled sectors in transitional economies.

    Notes: This paper is concerned with exploring the barriers to cross-border trade union cooperation among graphical workers in Europe. Highlighting the increasing globalisation of graphical multinationals, the paper illustrates that graphical unions cannot restrict their activities to developments within national boundaries. As such it highlights some of the obstacles that unions face in attempting to instigate transnational cooperation strategies. These obstacles include: the role of employers, the prevailing practices of the unions, employee reticence, the role of the law and resource constraints. It concludes by stressing the continuing need to strengthen cross-border trade union networks with the ability to impose effective sanctions against the unbridled growth of multinational power.

    Notes: A lower national minimum wage for 18- to 21-year-olds and the exclusion of all workers under 18 prompted fears of a distortion in the British labour market and an undermining of training initiatives. Empirical data collected from employers in two low paying sectors, revealing the full utilisation of young workers and under-utilisation of training initiatives, ensure these fears are not justified and that the government's basis for the lower rate cannot be substantiated.

    Notes: The French system of continuing vocational training was set up in 1970 by an intersectoral collective agreement that was then followed by legislation. More than 30 years on, the economic and social context has changed and the system now faces new challenges. In 2001 and again in 2003 the social partners embarked upon new negotiations in a bid to redesign the system. Analysis of the negotiation process and of its outcomes  reveals  both  the  persistence  of  societal  characteristics  and  the  emergence  of significant innovations, particularly in the individualisation of training. This dual trend is explained by the characteristics of the actors involved as well as by the weakness of the state.

    Notes: The extraordinary growth in foreign direct investment coupled with the widespread declination of union penetration has increasingly allowed multinationals to pit unions across borders as competitors for investment and jobs. Based on a theoretical analysis of the exercise of power in a prisoner's dilemma game, the essential conditions and incentives for cooperation among unions across borders for the purpose of collective bargaining with multinationals are identified and practical, strategic-level implications for transnational interunion partnerships are addressed.

    Notes: In response to Schmidt, Le, and Ilies' (2003) call for further assessment of transient error variance in measures of key individual difference variables, the current study examines transient error estimates for eight speeded cognitive ability scales and a composite scale. One hundred twenty-three participants were tested on two occasions with a 1-week interval between administrations. Estimates of transient error ranged from a low of .01 to a high of .18, with an average value of .09. The coefficient of equivalence, based on the split-half method, resulted in overestimates of reliability by as little as 1.90% to as much as 25.96%, with an average 12.96%.

    Notes: Although recruitment researchers often discuss influences on decisions to apply for jobs, few studies assess actual application behavior. This study of individuals who expressed an interest in a firefighter job revealed that applying was related to recruiting source informativeness and organizational familiarity. Source informativeness was not related to self-selection out of the process after application or performance on the selection process, but was related to perceptions of familiarity and to applicant demographics. Implications for recruitment are discussed.

    Notes: Critics and advocates of union–management partnership agreements offer competing assessments of the potential outcomes for workplace union representation. These include the attenuation of the role of lay activists and intra-union conflict. In this case study of Amicus-MSF at Legal & General partnership involved centralised decision making, membership loss and activist-leadership tensions, but these were temporary. With employer support the local union leadership ‘cultivated’ a cadre of pro-partnership activists with extended reach into management decision making, increasing membership and strengthening workplace organisation.

    Notes: An international foundation for the promotion of basic research in biomedicine, the Boehringer Ingelheim Fonds (B.I.F.), reports that fellowships are awarded to post-graduate researchers according to the following main criteria: (1) scientific quality as demonstrated by the applicant's achievements to date, (2) the originality of the proposed research project, and (3) the scientific standing of the laboratory where the research will be conducted. Using the Boolean probit statistical technique, this study examines the multiple conjunctural causation that a fellowship will be awarded only if all three of these criteria are assessed positively by the B.I.F. peer review committee. In agreement with the prescriptive principles of the foundation the results suggest that the B.I.F. approves applications only if all of the three criteria are rated positively.

    Notes: This paper identifies the constraints and opportunities facing trade unions in post-socialist societies through a comparison of the Russian and Chinese cases. The paper charts the changing role of trade unions in the integration of state-socialist economies into global capitalism and argues that this presents the trade unions with a dilemma: whether to reconstitute their traditional role through collaboration with management and the state apparatus, or whether to develop their ability to defend the rights and interests of workers. While the former offers the line of least resistance, there are progressive elements pushing for change in both trade union movements.

    Notes: Standardized tests are commonly used to select individuals in both pre-employment and educational settings. Nevertheless, research has yet to sufficiently explore the relationship between test anxiety (TA) and test performance in selection contexts. The goal of this study was to assess the dimensionality of TA, the relations between TA and test performance, and the impact of gender on TA within the realm of personnel selection. Test anxiety was found to be bi-dimensional and negatively related to performance on a cognitively based selection instrument. Gender moderated the relation between TA and test performance, with stronger associations for males. This finding is consistent with the sex-linked anxiety coping theory that is advanced here. Implications of this study and avenues for future research are discussed.

    Notes: A situational judgment test (SJT) and a Big 5 personality test were administered to 203 participants under instructions to respond honestly and to fake good using a within-subjects design. Participants indicated both the best and worst response (i.e., Knowledge) and the most likely and least likely response (i.e., Behavioral Tendency) to each situation. Faking effect size for the SJT Behavioral Tendency response format was (d=.34) when participants responded first under honest instructions and (d=.15) when they responded first under faking instructions. Those for the Big 5 dimensions ranged from d=.26 to d=1.0. For the Knowledge response format results were inconsistent. Honest condition Knowledge SJT scores were more highly correlated with cognitive ability (r=.56) than were Behavioral Tendency SJT scores (r=.38). Implications for researchers and practitioners are discussed.

    Notes: Applied psychologists have long been interested in the relationship between applicant personality and employment interview ratings. Analysis of data from two studies, one using a situational interview and one using a behavioral interview, suggests that the correlations of structured interview ratings with self-report measures of personality factors are generally rather low. Further, a small meta-analysis integrates these two studies and the limited previous literature to arrive at a similar conclusion – there is relatively little relationship between structured interviews and self-reported personality factors.

    Notes: In this study, we investigated the moderating role of interdependence (a personality trait that measures the extent to which individuals desire working in a group-based, cooperative setting) on the relationship between competitiveness and one-year objective sales performance. On the basis of data from 133 sales representatives, results indicated that: (a) competitiveness was related to objective sales performance; and (b) interdependence moderated the relationship between competitiveness and objective sales performance such that competitiveness predicted objective sales performance more strongly for those who scored low in interdependence versus those who scored high in interdependence. Implications for sales selection and reward systems and directions for future research are considered.

    Notes: Recruiters infer personal traits from job applicants' resumés and use these inferences in evaluating job applicants' employability. No research to date, however, has determined if resumé reviewers' inferences of applicants' personality drawn solely from resumé biographical data are valid. In the present study, resumé reviewers (N=52) examined one of two applicant resumés and then described the applicant's personality based on the Big 5 taxonomy. Validities of reviewers' inferences concerning applicant personality were assessed by correlating resumé reviewers' judgments with applicants' self-reported Big 5 personality scores. Results suggested that valid personality inferences are possible based solely on resumé evaluation. We also found evidence suggesting that attending a brief training session may enhance reviewers' accuracy when inferring applicants' personality from resumé information.

    Forming Composites of Cognitive Ability and Alternative Measures to Predict Job Performance and Reduce Adverse Impact: Corrected Estimates and Realistic Expectations (2005)

    Notes: Although there has been empirical attention paid to the criterion-related validity of predictor composites, there has been much less attention paid to the standardized ethnic group differences associated with these composites. One important area of inquiry in predictor composite research is the influence of adding predictors to a test of general mental ability. The limited empirical literature on this practice is mixed, but the prevailing expectation is that there is likely to be higher validity and less adverse impact. Unfortunately, much of the previous work is limited by the presence of inaccurate validity and standardized ethnic group difference values. In this analysis we formed meta-analytic matrices to more accurately estimate the validity and standardized ethnic group differences of several composites that combine a measure of cognitive ability with measures of conscientiousness, a structured interview, or biodata. While results were somewhat complex, we found that adding alternative predictors does not result in a situation in which validity automatically goes up and adverse impact potential automatically goes down. In fact, the reductions in adverse impact (if any) from adding “non-cognitive” predictors were more modest than much of the literature suggests.

    Notes: Abstract. The two approaches most commonly applied to characterizing the chemical form and ‘reactivity’ of metals in the soil solid phase are sequential extraction procedures (SEPs) and isotopic dilution (ID). The development and limitations of both approaches are described and their application to contaminated soils discussed. It may be argued that ID offers a better means of discriminating between ‘reactive’ and ‘inert’ forms of metal. However, the literature on SEPs is considerably larger, providing greater scope for comparative analysis of new data. Although ID methods are subject to operational constraints, the procedural dependency of SEPs is probably much greater. Thus greater effort has been expended to standardize and verify methodologies for SEPs. However, despite achieving a level of ‘political ratification’ at the procedural level, the use of SEPs within risk assessments for planning or development purposes is currently almost absent. The future for ID methods in this context may lie in site-specific risk assessments that include improved methods for the prediction of metal solubility and bioavailability.

    Notes: Abstract. Chemical analysis alone is inadequate for comprehensively assessing the impact of soil pollution on biota. The term bioavailability can only be applied in a context specific to a target biological receptor or a proven chemical surrogate. Integration of biological and chemical data can often yield significant advances in hazard assessment and act as a suitable baseline for making site-specific risk assessments. Here, the value of biological techniques is discussed and their application described. The relative merit of test selection is considered and the new direction being developed in sublethal assessments. Currently, however, one of the major limitations is the seeming lack of flexibility of many assays in that they are either applicable to agricultural systems or industrial scenarios, but rarely to both. As a consequence, few assays have internationally adopted protocols. The introduction of new methods and the continued improvement and refinement of assays make this area of soil science dynamic and responsive.

    Notes: Abstract. A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (N) and sulphur (S), are a major concern. Governments have initiated extensive regulatory frameworks, including various land use policies, in an attempt to control or reduce the losses. This paper presents an overview of critical input and loss processes affecting N and S for temperate climates, and provides some background to the discussion in subsequent papers evaluating specific farming systems. Management effects on potential gaseous and leaching losses, the lack of synchrony between supply of nutrients and plant demand, and options for optimizing the efficiency of N and S use are reviewed. Integration of inorganic and organic fertilizer inputs and the equitable re-distribution of nutrients from manure are discussed. The paper concludes by highlighting a need for innovative research that is also targeted to practical approaches for reducing N and S losses, and improving the overall synchrony between supply and demand.

    Notes: Abstract. Sustainable management of nutrients in agricultural systems is critical for sufficient production of nutritious foods and to minimize environmental pollution. In this overview, we discuss some of the most important factors influencing nutrient cycling, and how practices for sustainable nutrient management can be optimized. In most cases, problems are associated with excessive use of nutrients (manures, other organic amendments, and inorganic fertilizers). Options for dealing with such problems at the farm level include: reducing nutrient inputs to balance exports, increasing the land area on which manures are applied, and export of excess nutrients from the farm in the form of value-added products. These strategies can be used singly, or in combination. Nutrients in the human food chain are often not recycled back to primary crop production. To manage such issues, and avoid regional nutrient accumulations, we need to develop a better understanding of large-scale nutrient flows, and develop policies to manage them. We stress the importance of scale when considering nutrient management in the future.

    Phosphorus management in balanced agricultural systems (2005)

    Notes: Abstract. The practice of large phosphorus (P) additions to agricultural land has resulted in an increased depletion of limited mineable rock phosphate resources, P accumulation in soils with an increased risk for P losses, and intensified eutrophication and deterioration of water quality in recipient water bodies. A number of measures have been used to reach balance between P inputs and outputs in agricultural systems, with the goal of achieving improved P use efficiency, sustained high crop yields and reduced P losses. This paper discusses how this goal may be achieved. Results from a Swedish long-term fertility experiment combined with results of a P leaching study using a selection of soils from the fertility experiment are used to evaluate the effects of a balanced P system on yields, soil P levels and P leaching. Three P fertilizer application strategies are compared (zero P, replacement P, and a treatment where surplus P fertilization was used to achieve a rapid increase in the soil P status). The replacement P strategy appeared to be the most sustainable system but P fixation in this system must be accounted for. When surplus P rates were applied, increased crop yields were counterbalanced by poorer use efficiency and P accumulation in soil. Topsoil P content was a poor predictor of P leaching. Instead, balancing P inputs and outputs represents a first step in the management of P losses, but additional, site-specific measures are required to counteract site-specific factors responsible for P losses.

    Nutrient management in low input grazing–based systems of meat production (2005)

    Notes: Abstract. Low input grazing-based meat production is often practised on land where alternative land use is restricted and where high biodiversity warrants specific environmental payments. Although these systems are characterized by low external nutrient inputs, significant nutrient losses may occur per unit of produce, even though losses per unit area are low. If the aim is to have animal production without further eutrophication of watercourses, these losses should be minimized,. However, if nutrient-poor grasslands characterized by high biodiversity are the aim, some losses must be accepted to balance nutrient inputs by atmospheric deposition. The impact of grazing animals on nutrient dynamics in grasslands is reviewed in this paper, and options to further improve nutrient management are discussed. It is concluded that nutrient management should largely be addressed indirectly through management of animal behaviour in relation to grazing and supplemental feeding, as well as through optimization of the seasonal distribution of livestock size. A case study indicated that N losses from a cattle farm could be reduced considerably by these means, while animal production could actually be improved. Sustainability issues and trends in legislative and social pressures on low input grazing-based systems of animal production are discussed in relation to nutrient management and practical recommendations.

    Notes: Abstract. A model of soil variability as a continuous background process with superimposed point contamination was applied to 569 measurements of metal concentrations (Cr, Ni and Pb) in the topsoils of Sheffield, England. Robust estimators of the variogram were shown to be required to describe spatial variation of the metal concentrations at most sampled locations. This is diagnostic of the presence of a contaminant process. Values of the standardized kriging error from the cross-validation of each datum were used to identify spatial outliers for each metal. The ordinary kriged estimates of Cr, Ni and Pb were mapped after removing the outliers to estimate the background variation. Each of the 35 spatial outliers that occured in gardens have concentrations exceeding their Soil Guideline Value for residential land use with plant uptake, highlighting a potentially significant exposure pathway. The frequent observation of coal and furnace waste at these sites suggests that their dispersal, following domestic use and industrial processes, respectively, represents a significant point contaminant process. There was no evidence for spatial clustering of the point process. However, the spatial outliers of Cr and Ni showed a significant association with disturbed sites identified from historical land use maps, in part due to their prevalence in areas of historical steel manufacture. The magnitude of diffuse pollution for each metal in the urban soil was estimated by removing the spatial outliers and comparing robust measures of location with those from a survey of soils developed over the same parent materials in adjacent rural and peri-urban environments. The Winsorized mean Pb concentrations in urban topsoil (203 mg kg−1) were twice the value in the rural environment (101 mg kg−1), highlighting a very substantial diffuse Pb load to urban soils. The equivalent estimated diffuse components in urban soils for Cr and Ni were, respectively, 25% and 14% higher than the rural soils.
