    Description: The introduction of the German parental leave benefit (Elterngeld) applied to all children born on 1 January, 2007 or later. The Elterngeld considerably changed the amount of transfers to families during the first two years postpartum. We show that the incentives created by using a cut-off date led more than 1,000 parents to postpone the delivery of their children from December 2006 to January 2007. Concerning potential adverse impacts on health outcomes of children we find a slight increase in average birth weight and the rate of children with high birth weight (>4,000 g).

    Notes: In this study, the reduction of patulin content in apple juice concentrates during 6 months of storage at 22 and 30C was investigated. Results demonstrated that reduction in patulin content was dependent on the storage temperature and time. Patulin reductions after 1 month of storage at 22 and 30C were in the ranges of 45–64% and 66–86%, respectively. Levels of patulin were below detectable limits after 4 months of storage at 22 and 30C.

    Notes: The sensitivity of pulsed electric fields (PEF)-treated E. coli O157:H7 cells to subsequent holding in apple juice has been evaluated. Escherichia coli O157:H7 cells in apple juice were resistant to PEF. A PEF treatment of 400 µs at any electrical field strength was not sufficient to inactivate one log10cycle of cells. However, PEF injured a large proportion of E. coli O157:H7 cells that became sensitive to a subsequent storage under refrigeration in apple juice. The total lethal effect of the combined process depended on the electrical field strength and storage time. The combination of a PEF treatment at 25 kV/cm for 400 µs and a subsequent storage of the apple juice under refrigeration for 48 h allowed five log10cycles of inactivation to be achieved. The combination of PEF and maintenance under refrigeration has been demonstrated to be an effective pasteurization method, by sufficiently reducing the presence of E. coli O157:H7 in apple juice in order to meet U.S. FDA recommendations.

    Notes: To estimate the incidence and levels of Listeria spp. in an industrial poultry processing plant, samples of chicken breast meat, livers, surfaces of saws and tables, hands and gloves were analyzed. Forty percent of the breast samples presented Listeria: L. monocytogenes, L. innocua and L. grayi. Liver samples were contaminated by L. innocua and L. grayi. High levels of Listeria monocytogenes were found on saws (<30–2400 MPN/equipment) and tables (<30–11,000 MPN/equipment). Hands were contaminated by L. monocytogenes, L. innocua and L. grayi and gloves with L. innocua and L. grayi. The levels of Listeria on hands and gloves were low (<110 MPN/hand). L. monocytogenes serotypes were 1/2a, 1/2b, 1/2c and 4b. Overall, the study demonstrated the high prevalence of Listeria spp. and specifically L. monocytogenes in chicken breast meat, equipment and hands. Improvements and innovations at the poultry processing plant may effectively reduce final production contamination with Listeria.

    Notes: Salmonella enteritidis was cultivated in egg yolks and submitted to boiling and frying methods commonly used in domestic conditions in the south of Brazil. The results have demonstrated a rapid growth of the microorganism reaching counts of 9.0 log10at 168 h. When contaminated shell eggs were placed in water and slowly heated, a population of approximately 7.0 log10was completely inactivated after boiling for 1 min. However, in eggs placed directly in boiling water, the reduction was only 1.35 log10after 1 min, and the entire population was eliminated after 3 min. A reduction of approximately 2.78 log10was observed after frying for 1.5, 2.0 and 2.5 min. Even though the solidification of yolk has been pointed out as an indicator of S. enteritidis elimination in egg yolks, attention should be given to frying procedures, as considerable high levels of this microorganism could be recovered even from solidified yolks.

    Notes: Sixty samples of salted fish (Molouha) were randomly collected from Ismailia City, Egypt to evaluate the quantitative, qualitative and toxigenicity of xerophilic mold. The results revealed that 50 (83.3%) out of 60 salted fish analyzed were contaminated by xerophilic mold, while 16.7% were negative. The mean value of total xerophilic mold was 2.45 ± 0.95 log10 cfu/g. Aspergillus spp. was the most predominant xerophilic mold (58.2%) in the fish followed by Penicillium spp. (32.7%). Aspergillus niger and P. verrecosum var. verrecosum were the most predominant mold strains in investigated samples. Thirty-one (18.8%) toxigenic xerophilic mold strains out of 165 isolated xerophilic mold species found to be Sterigmatocystin and Aflatoxin B2, G1mycotoxin producers. Salted fish processing should be controlled by the authority in concern to solve the poor mycological quality of retail salted fish in Ismailia city. Measures must be developed to control the growth and activity of xerophilic mold in salted fish.

    Notes: Degradation of dissolved chlorinated solvents using granular iron is an established in situ technology. This paper reports on investigations into mixing iron and bentonite with contaminated soil for in situ containment and degradation of dense nonaqueous phase liquid source zones. In the laboratory, hypovials containing soil, water, bentonite, iron, and free-phase trichloroethene (TCE) were assembled. Periodic measurement of TCE, chloride, and degradation products showed progressive degradation of TCE to nondetectable levels. Subsequently, a demonstration was conducted at Canadian Forces Base Borden near Alliston, Ontario, Canada, where, in 1991, a portion of the surficial aquifer was isolated and free-phase tetrachloroethene (PCE) was introduced. Using a drill rig equipped with large-diameter mixing blades, three mixed zones were prepared containing 0%, 5%, and 10% granular iron by volume. The bentonite was added to serve as a lubricant to facilitate injection of the iron and to isolate the contaminated zone. Analysis of core samples showed reasonably uniform distributions of iron through the mixed zones. Monitoring over a 13-month period following installation showed, relative to the control, a decline in PCE concentrations to virtually nondetectable values. Reaction rates in the laboratory tests were similar to those reported in the literature, while the rate in the field test was substantially lower. The lower rate may be a consequence of mass transfer limitations under the static conditions of the field test. Results indicate that mixing iron and bentonite into source zones may be an effective means of source-zone remediation, with the particular advantage of being relatively immune to effects of geologic heterogeneity.

    Notes: Matrix diffusion can attenuate the rate of plume migration in fractured bedrock relative to the rate of ground water flow for both conservative and nonconservative solutes of interest. In a system of parallel, equally spaced constant aperture fractures subject to steady-state ground water flow and an infinite source width, the degree of plume attenuation increases with time and travel distance, eventually reaching an asymptotic level. The asymptotic degree of plume attenuation in the absence of degradation can be predicted by a plume attenuation factor, β, which is readily estimated as R′ (φm/φf), where R′ is the retardation factor in the matrix, φm is the matrix porosity, and φf, is the fracture porosity. This dual-porosity relationship can also be thought of as the ratio of primary to secondary porosity. β represents the rate of ground water flow in fractures relative to the rate of plume advance. For the conditions examined in this study, β increases with greater matrix porosity, greater matrix fraction organic carbon, larger fracture spacing, and smaller fracture aperture. These concepts are illustrated using a case study where dense nonaqueous phase liquid in fractured sandstone produced a dissolved-phase trichloroethylene (TCE) plume ∼300 m in length. Transport parameters such as matrix porosity, fracture porosity, hydraulic gradient, and the matrix retardation factor were characterized at the site through field investigations. In the fractured sandstone bedrock examined in this study, the asymptotic plume attenuation factors (β values) for conservative and nonconservative solutes (i.e., chloride and TCE) were predicted to be ∼800 and 12,210, respectively. Quantitative analyses demonstrate that a porous media (single-porosity) solute transport model is not appropriate for simulating contaminant transport in fractured sandstone where matrix diffusion occurs. Rather, simulations need to be conducted with either a discrete fracture model that explicitly incorporates matrix diffusion, or a dual-continuum model that accounts for mass transfer between mobile and immobile zones. Simulations also demonstrate that back diffusion from the matrix to fractures will likely be the time-limiting factor in reaching ground water cleanup goals in some fractured bedrock environments.

    Notes: Naturally occurring long-term mean annual recharge to ground water in Nebraska was estimated by a novel water-balance approach. This approach uses geographic information systems (GIS) layers of land cover, elevation of land and ground water surfaces, base recharge, and the recharge potential in combination with monthly climatic data. Long-term mean recharge > 140 mm per year was estimated in eastern Nebraska, having the highest annual precipitation rates within the state, along the Elkhorn, Platte, Missouri, and Big Nemaha River valleys where ground water is very close to the surface. Similarly high recharge values were obtained for the Sand Hills sections of the North and Middle Loup, as well as Cedar River and Beaver Creek valleys due to high infiltration rates of the sandy soil in the area. The westernmost and southwesternmost parts of the state were estimated to typically receive < 30 mm of recharge a year.

    Notes: At three industrial sites in Ontario, New Hampshire, and Florida, tetrachloroethylene (PCE) and trichloroethylene (TCE), released decades ago as dense nonaqueous phase liquids (DNAPLs), now form persistent source zones for dissolved contaminant plumes. These zones are suspended below the water table and above the bottoms of their respective, moderately homogeneous, unconfined sandy aquifers. Exceptionally detailed, depth-discrete, ground water sampling was performed using a direct-push sampler along cross sections of the dissolved-phase plumes, immediately downgradient of these DNAPL source zones. The total plume PCE or TCE mass-discharge through each cross section ranged between 15 and 31 kg/year. Vertical ground water sample spacing as small as 15 cm and lateral spacing typically between 1 and 3 m revealed small zones where maximum concentrations were between 1% and 61% of solubility. These local maxima are surrounded by much lower concentration zones. A spacing no larger than 15 to 30 cm was needed at some locations to identify high concentration zones, and aqueous VOC concentrations varied as much as four orders of magnitude across 30 cm vertical intervals. High-resolution sampling at these sites showed that three-quarters of the mass-discharge occurs within 5% to 10% of the plume cross sectional areas. The extreme spatial variability of the mass-discharge occurs even though the sand aquifers are nearly hydraulically homogeneous. Depth-discrete field techniques such as those used in this study are essential for finding the small zones producing most of the mass-discharge, which is important for assessing natural attenuation and designing remedial options.

    Notes: Long-term reactivity and permeability are critical factors in the performance of granular iron permeable reactive barriers (PRBs). Thus it is a topic of great practical importance, as well as scientific interest. In this study, four types of source solutions (distilled H2O, 10 mg/L TCE, 300 mg/L CaCO3, and 10 mg/L TCE + 300 mg/L CaCO3) were supplied to four columns containing a commercial granular iron material. In all four columns, gases accumulated to ∼ 10% of the initial porosity and resulted in declines in permeability of ∼ 50% to 80%. In the columns receiving CaCO3, carbonate precipitates accumulated to ∼ 7% of the initial porosity, with no apparent decline in permeability. The data indicate that precipitates formed initially at the influent ends of the columns, reducing the reactivity of the iron in this region. As a consequence of the reduced reactivity, calcium and bicarbonate migrated further into the column, to precipitate in a region where the reactivity remained high. Thus precipitation occurred as a moving front through the columns. The results suggest improved methods for PRB design and rehabilitation, and also suggest improvements that are needed in the mathematical models developed for predicting long-term performance.

    Notes: This paper presents the design of the passive-discrete water sampler (PDWS) which has been developed to facilitate investigations of flow partitioning in fractured rocks. The PDWS continuously isolates seeping water into discrete samples while monitoring the seepage rate. The PDWS was used in a flow and transport experiment that investigated fracture-matrix interactions. During the experiment, a mix of conservative tracers with significantly different diffusion coefficients (lithium bromide [LiBr] and pentafluorobenzoic acid [PFBA]) was introduced along a fault located in fractured tuffs, and water seeping through the lower end of the fault was collected by the PDWS and analyzed for tracer concentrations. Preliminary results from this investigation show that samples of effluent captured by the PDWS effectively retained temporal changes in the chemical signature, while providing seepage rates.

    Notes: Three-dimensional grids representing a heterogeneous, ground water system are generated at 10 different resolutions in support of a site-scale flow and transport modeling effort. These grids represent hydrostratigraphy near Yucca Mountain, Nevada, consisting of 18 stratigraphic units with contrasting fluid flow and transport properties. The grid generation method allows the stratigraphy to be modeled by numerical grids of different resolution so that comparison studies can be performed to test for grid quality and determine the resolution required to resolve geologic structure and physical processes such as fluid flow and solute transport. The process of generating numerical grids with appropriate property distributions from geologic conceptual models is automated, thus making the entire process easy to implement with fewer user-induced errors. The series of grids of various resolutions are used to assess the level at which increasing resolution no longer influences the flow and solute transport results. Grid resolution is found to be a critical issue for ground water flow and solute transport. The resolution required in a particular instance is a function of the feature size of the model, the intrinsic properties of materials, the specific physics of the problem, and boundary conditions. The asymptotic nature of results related to flow and transport indicate that for a hydrologic model of the heterogeneous hydrostratigraphy under Yucca Mountain, a horizontal grid spacing of 600 m and vertical grid spacing of 40 m resolve the hydrostratigraphic model with sufficient precision to accurately model the hypothetical flow and solute transport to within 5% of the value that would be obtained with much higher resolution.

    Notes: Proper management of ground water resources requires knowledge of the rates and spatial distribution of recharge to aquifers. This information is needed at scales ranging from that of individual communities to regional. This paper presents a methodology to calculate recharge from readily available ground surface information without long-term monitoring. The method is viewed as providing a reasonable, but conservative, first approximation of recharge, which can then be fine-tuned with other methods as time permits.Stream baseflow was measured as a surrogate for recharge in small watersheds in southeastern Wisconsin. It is equated to recharge (R) and then normalized to observed annual precipitation (P). Regression analysis was constrained by requiring that the independent and dependent variables be dimensionally consistent. It shows that R/P is controlled by three dimensionless ratios: (1) infiltrating to overland water flux, (2) vertical to lateral distance water must travel, and (3) percentage of land cover in the natural state. The individual watershed properties that comprise these ratios are now commonly available in GIS data bases.The empirical relationship for predicting R/P developed for the study watersheds is shown to be statistically viable and is then tested outside the study area and against other methods of calculating recharge. The method produces values that agree with baseflow separation from streamflow hydrographs (to within 15% to 20%), ground water budget analysis (4%), well hydrograph analysis (12%), and a distributed-parameter watershed model calibrated to total streamflow (18%). It has also reproduced the temporal variation over 5 yr observed at a well site with an average error < 12%.

    Notes: Article 14 of the Water Framework Directive requires member states to demonstrate that they are enabling increased public participation in water governance issues at the river basin level. Yet little research has been conducted to understand in what regard water governance bodies are held by the public. In particular, few studies have concentrated on which water resource management issues concern consumers at the catchment and sub-catchment scale within England and Wales. A household study was conducted in 2003 along the River Nene catchment in the east of England to understand in more detail the range of these consumer perceptions and attitudes at different spatial scales, focusing on water resource management issues such as flooding, sector performance and policy making. The results of the survey demonstrate that formulating policy at the catchment scale does not always capture the diversity of opinion or the range of legitimacy issues which concern consumers at the sub-catchment level. The paper concludes that public participation initiatives may be improved by paying closer attention to the various legitimacy concerns at the catchment and sub-catchment scales.

    Notes: Incineration has suffered from a sustained campaign of misinformation. Consequently it has been regarded as the least sustainable option for the treatment of wastes, including sewage sludge. By looking carefully at the issues surrounding the incineration of sewage sludge, as an example, it can be seen that reality does not support the commonly held view. Modern plants are an effective means of recovering the energy value of sludge and at the same time offer a continuous operation, which is independent of weather or land constraints.Of course incineration needs to be regulated and EU Directives and National Regulations set the emission standards. The technology is such that these standards can be met, and more than this, the systems are capable of upgrading as more stringent standards are imposed.Concerns over NOx, dioxins, metals and pathogens are highlighted. In addition the permitting process is discussed. None of these should present a barrier to the implementation of incineration projects. Indeed the paper goes further and demonstrates that there is likely to be an increasing role for incineration as landfill, recycling to agricultural land and other options become more restrictive.

    Notes: The effect of controlling the pre-coagulation regime on downstream ultrafiltration of raw upland waters has been investigated. It has been shown that zeta potential can be used to detect changes in the coagulation process and hence to determine appropriate dosage levels. This is important, as incomplete coagulation has a detrimental effect on ultrafiltration membrane performance, particularly in terms of fouling caused by excess iron. Submerged hollow-fibre membrane units yield superior performance with pre-coagulation and sufficient slow mixing of coagulant guarantees high permeate flow recovery after backwashing. Fouling by natural organic matter can be remedied by conventional cleaning techniques. However, fouling due to excess iron can only be removed by heating the cleaning solution. The associated costs are thus two-fold; that of excess coagulant and that of cleaning.

    Notes: Climate risk management is a new and evolving area and many decisions are likely to be affected by climate risks over the long-term. This paper presents a decision-making framework designed for managing climate alongside nonclimate risk factors. The framework describes a process that should help identify and manage these risks. It can be used to help decision-makers answer questions about whether adaptation is required, and, if so, which measures should be implemented. Adaptive management is recommended as a useful approach for dealing with climate and other uncertainties. This paper describes an application of the framework to a water resources case study. Feedback from training workshops based on four different case studies suggests the framework provides at minimum a useful (post-hoc) decision analysis tool. Potential users, who include planners, consultants and policy-makers have been largely positive about the prospective utility of the framework.

    Notes: Some landfill site operators use wastewater treatment plants for the discharge of complex leachate waste. However, for the water company involved in managing the wastewater plant, leachates can pose a problem to the quality of the effluent, due to the high levels of Chemical Oxygen Demand (COD), ammonia and inorganic metal constituents. Electrochemical oxidation of landfill leachate has been successfully used by researchers(1,2,3,4) with current densities of 5 to 100 mA/cm2. A new laboratory system has been developed which utilises a low current density of 2.42 mA/cm2 and the performance has been evaluated with synthetic and ’real’ landfill leachates from 2 wastewater sites.This system reduces COD of synthetic mixtures by 58%, with complete removal of ammonia. For real leachates, 5 out of 8 samples resulted in ammonia reduction, with 2 samples experiencing approximately. 60% COD reduction. Power costs for treatment have been determined and the potential for a full-scale installation considered.

    Notes: Evaluation of drinking water quality for Jenln district in Palestine was carried out for the years 1997, 1998, and 1999, respectively. Only 53.1 %, 85.4% and 69.6% of the drinking water samples tested for free chlorine residual, total coliforms and faecal coliforms, respectively are within the limits of the Palestinian and International standards. The seasonal variation of bacteriological and chemical quality of drinking water was investigated. It was found out that the summer season has the best quality and the winter has the worst. There remains some ignorance in testing the drinking water in the villages and towns in Jenin district. Huge efforts are required to improve the drinking water quality in Jenin district, as well as other Palestinian districts, through public awareness, training of governmental Inspectors, in addition to a strict monitoring system for water quality.

    Notes: flooding occurred in many locations in the united kingdom in the autumn/winter of 2000. One of the worst affected areas was Robertsbridge, in East Sussex, where over that winter, some properties were flooded up to eight times following those events, the environment agency targeted defences for this high-risk township as one of its high priority projects to‘fast-track’to implementation.studies started in January 2001, which recommended a stand-alone scheme that would project the township against the 1% probability flood. Project development progressed on a‘fast-track’basis to allow construction to start in September 2002 with completion planned in the summary of 2003.project development and implementation is always an obstacle course but the‘fast-track’approach magnifies the obstacle and introduces new ones. This paper describes experience from the Robertsbridge flood allevation scheme, with particular reference to some of the problems encountered, both technical and procedural

    Notes: The performance of a novel industrial membrane bioreactor (MBR) comprising denitrification, nitrification and ultrafiltration for the secondary treatment of primary treated animal rendering wastewater has been compared with an experimental, low-cost and novel vertical-flow constructed wetland planted with Typha latifolia L. (Reedmace or Broad-leaved Cattail). The process wastewater followed pre-treatment by dissolved air flotation (DAF). The mean DAF effluent gave highly variable chemical oxygen demand (COD) and ammonia concentrations of 5816 (standard deviation (SD): 3005.0) and 614 (SD: 268.7) mg/l, respectively. The mean MBR effluent for COD and ammonia was 37 and 86 mg/l, respectively. The mean treatment performance of the constructed wetland for COD, ammonia and suspended solids was 205, 67 and 57 mg/l, respectively.

    Notes: A model was developed and tested to investigate the effects of various parameters on the processing costs of anaerobic digestion. The model was based on empirical data collected from full-scale plants which varied in size from 35,000 to 900,000 population equivalents. (Equivalent to loading rates of 0.5 to 2.7 kg VS/m3/d.) In spite of different operating regimes and conditions of the plants analysed, various relationships were discovered between: sludge quality and volatile solids destruction; sludge quality and biogas yield; and, effluent volatile solids and dewatering. Where correlations existed, these were used to make predictions on operating costs of the digestion and dewatering plant based on sensitivity analysis. The results of the model were used to make recommendations on how to optimise the operation of an anaerobic digestion plant.

    Notes: Regulations Introduced in 1999 obliged water companies In England and Wales to conduct risk assessments of their treatment works to establish whether there was a significant risk from Cryptosporidium oocysts in the water supplied. More than 330 treatment works were identified as being at risk, just over half of which were plants treating groundwater. This paper provides an overview of what water companies themselves identified as the most at-risk settings for their groundwater-based works in terms of aquifer and type of supply. Evaluation of results from the subsequent continuous monitoring regulatory regime that came into force on many of these supplies could validate the primarily qualitative nature of the initial assessments of at-risk settings. There would also be public health benefits from confirmation of whether currently-employed risk assessment methods are well-founded because similar procedures could then be applied with confidence to the many small private supplies In Britain.

    Notes: The Ouse Washes is an area of Hood washland in Cambridgeshire. The site has been designated as an SPA and SAC, due to the presence of Spined Loach in the Old Bedford River and River Deiph and the invaluable over wintering and nesting habitats it offers for various nationally and internationally important species of birds. The site is currently thought to be in an unfavourable ecological condition, in terms of both the nutrient concentrations and the vegetation communities that populate the site. These factors affect the favourability of the site for both the Spined Loach and the bird populations. To restore favourable conditions to the Washes, a target vegetation community was defined for each discrete area of the site. Each of these communities had an ecohydrological prescription derived, which defined the required annual regime for mid-Held water table depth, flooding depth and duration and ditch nutrient concentration.A catchment-wide rainfall-runoff and nutrient transport model was used to derive flows and nutrient loads across the Washes under a range of catchment management scenarios. The model results for each discrete area of the Washes were analysed and the ecohydrological favourability under the different scenarios could then be quantified. By running various scenarios of different artificial influence and diffuse pollution conditions, the possible water and nutrient regime within the Washes was investigated and the suitability of different management options quantified relative to the target ecological requirements of the site. This allowed the Environment Agency to complete an Appropriate Assessment of the site, as required under the EU Habitats Directive.

    Notes: Hong Kong is an Asian city with nearly 7 million people. Because of the lack of natural resources, the local water supply is not adequate to meet the demand. Fresh water supply in Hong Kong relies on the cross border import of water from the East River (Dongjiang) in China. To conserve fresh water, seawater has been used for toilet flushing since the 1950s. In this paper, the current status of seawater for toilet flushing in Hong Kong is reviewed, and the future strategy toward sustainable toilet flushing water supply, including other alternatives, is discussed.

    Notes: Rapid groundwater drawdown has become the biggest threat to social-economic sustainability in the Hebei Plain. To determine the cause of the groundwater decline and develop a practical plan for long-term groundwater use, water-table fluctuation data were collected over a period of 20 years. Adopting a simplified water balance model, the average infiltration coefficient of precipitation and specific yield in the Hebei Plain from 1985–1995 were simulated and the groundwater level decline by water-use sectors and crops was calculated. Analysis showed that agricultural water use was the main reason for groundwater drawdown. Winter wheat was the most water-consuming crop, causing a significant decline of the water table. It is suggested that planting strategies should be adjusted and water-saving agricultural practices be carried out, to achieve sustainable groundwater use in the Hebei Plain.

    Notes: Published for World Water Day, 22 March 2005, WaterAid’s report ‘Getting to boiling point’ explores how the UK and other governments will fail to meet their water and sanitation promises to the world’s poor unless they improve their performance.Focusing on the financial waste and underinvestment which are currently trapping millions in poverty this report also gives national governments and the international community the routes forward which, if followed, could enable them to keep their promises to halve the proportion of people without safe water and sanitation by 2015 as set out in their Millennium Development Goals. With extensive data from 14 countries ‘Getting to boiling point’provides a baseline against which further progress on the world’s water and sanitation crisis can be measured. A summary of the report follows.

    Notes: Groundwater is an important resource in the UK, with 45% of public water supplies in the Thames Water region derived from subterranean sources. In urban areas, groundwater has been affected by anthropogenic activities over a long period of time and from a multitude of sources. At present, groundwater quality is assessed using a range of chemical species to determine the extent of contamination. However, analysing a complex mixture of chemicals is time-consuming and expensive, whereas the use of an ecotoxicity test provides information on (a) the degree of pollution present in the groundwater and (b) the potential effect of that pollution. MicrotoxTM, EcloxTM and Daphnia magna microtests were used in conjunction with standard chemical protocols to assess the contamination of groundwaters from sites throughout the London Borough of Hounslow and nearby Heathrow Airport. Because of their precision, range of responses and ease of use, Daphnia magna and MicrotoxTM tests are the bioassays that appear to be most effective for assessing groundwater toxicity. However, neither test is ideal because it is also essential to monitor water hardness. EcloxTM does not appear to be suitable for use in groundwater-quality assessment in this area, because it is adversely affected by high total dissolved solids and electrical conductivity.

    Notes: Effective implementation is crucial to the success of public policy. This paper focuses on the implementation of the EU Drinking Water Directive (80/778/EEC) in England and Wales and the Republic of Ireland. It demonstrates that the consumer can both positively and negatively affect implementation. It is concluded that, if water providers and regulators wish to improve their ability to shape and effectively implement water policy, they must engage with the consumer in a more informative and educational manner.

    Notes: Interactions between marine mammals and fishing gear are an issue of global concern. Entanglements in the western North Atlantic are a major source of injury and mortality for endangered large whales. In this study, entanglements of 31 right whales (Eubalaena glacialis) and 30 humpback whales (Megaptera novaeangliae) were analyzed to determine the types and parts of gear involved. When gear was identified, 89% (n= 32) of the entanglements were attributed to pot and gill net gear; however, a wide range of specific gear types were implicated. Despite gear recovery, gear type was not identified in 20% (n= 9) of the cases. Although pot gear was recovered from both species equally, gill net gear was less frequently retrieved from right whales (n= 2) than humpback whales (n= 11). When gear part was identified, 81% (n= 21) involved entanglements in buoy line and/or groundline. For right whales, the most common point of gear attachment was the mouth (77.4%); for humpback whales, the tail (53%) and the mouth (43%) were common attachment sites. Four right and three humpback whales in this sample were known to have died subsequent to entanglement. However, when identified, the gear types and parts involved in lethal cases were not substantially different from entanglements with non-lethal outcomes. Large whales can become entangled in a wide variety of fishing gear types and parts, and additional insight will depend on continued efforts to document entanglements and recover associated gear.

    Notes: Detailed knowledge about the history of colonization, population dynamics and behavior greatly enhance evaluation of genetic models of population units and migration rates in spatially structured populations. Here, the genetic uniqueness of harbor seals (Phoca vitulinia) in the eastern Baltic is evaluated in the light of new information on the distribution and abundance of Baltic and eastern North Sea populations during the last 11,000 yr, recent hunting statistics, and population counts. Archaeological records reveal that the Baltic population of harbor seals was founded about 8,000 yr ago. Adjacent populations in the North Sea areas were either small, or went extinct, and became significant only during the last 300 yr. This information generates the hypothesis that the Baltic population has been isolated during the last 8,000 yr, despite the lack of geographical barriers. We show that stochastic effects, isolation, and a documented recent population bottleneck can account for the low observed genetic variation in Baltic harbor seals.

    Notes: This paper attempts to project the trends of Steller sea lion (Eumetopias jubatus) populations in six subdivisions of the western Alaska population. The overall Western Alaska population has declined dramatically since the 1970s. Trends in half of the areas appear to have leveled-off and possibly to be on the increase. Bootstrapping has been used to provide confidence intervals on predictions for the 2004 counts. For the three areas in which we expect increases, the 95% confidence intervals on predictions were: Eastern Gulf (2,430–3,740), Central Gulf (3,260–3,660) and Central Aleutians (5,160–6,580). The Western Gulf counts have been somewhat erratic, with a gradual rate of decrease (about 2% per year) and wide confidence limits on a linear prediction (logarithmic scale) of 2,690–3,240. Trends in the Eastern Aleutians have been even more erratic, so that about all that can be inferred is that the population may be roughly stabilized. Only the Western Aleutians appear to be rapidly declining at about 10% per year, with a 95% confidence interval on a linear trend of 610–1,100. The predictions were made before the 2004 counts and are in reasonable accord with the 2004 counts. Age structure changes do not appeat to provide a viable explanation for the changing trends.

    Notes: Directional asymmetry (DA) of the lengths, diameters, and masses of the scapula, humerus, radius, and ulna were analyzed on a sample of 213 harbor porpoises from Denmark and West Greenland. The levels of DA were consistent across yearlings and older animals, mature and immature animals, sexes, and populations. All investigated variables showed significant DA favoring the right side. For the pooled sample, DA of lengths ranged from 0.2% SE 0.1 (ulna) to 1.2% SE 0.1 (scapula). DAs of diameters were 1.5% SE 0.2 for the humerus, 0.6% SE 0.1 for the radius, and 1.3% SE 0.2 for the ulna. DA of mass ranged from 2.8% SE 0.5 (humerus) to 4.3% SE 0.7 (ulna). The humerus and ulna had significantly larger mean diameter/ length ratios on the right side than the left, making them more robust. The large DA of scapula length indicates larger muscle mass associated with the right flipper, while the generally more robust right humerii and ulnae may be designed for higher levels of mechanical stress. These DAs and the examples of lateralized behavior recorded in cetaceans, point to the existence of lateralized use of the flippers at the population level in harbor porpoises and possibly other cetacean species.

    Notes: We estimate the abundance of sperm whales in a 7.8 million km2 study area in the eastern temperate North Pacific using data from a ship-based acoustic and visual line-transect survey in spring 1997. Sperm whales were detected acoustically using a hydrophone array towed at 15 km/h and 100 m depth. The hydrophone array was towed for 14,500 km, and locations were estimated acoustically for 45 distinct sperm whale groups. Whales producing slow clicks (>2-s period) were detected at greater distance (up to 37 km), and the estimation of effective strip widths was stratified based on initial click period. Visual survey effort (using 25° binoculars and naked eyes) covered 8,100 km in Beaufort sea states 0–5 and resulted in only eight sightings. The effective strip width for visual detections was estimated from previous surveys conducted using the same methods and similar vessels in the eastern Pacific. Estimated sperm whale abundance in the study area was not significantly different between acoustic (32,100, CV = 0.36) and visual (26,300, CV = 0.81) detection methods. Acoustic techniques substantially increased the number of sperm whales detected on this line-transect survey by increasing the range of detection and allowing nighttime surveys; however, visual observations were necessary for estimating group size.

    Notes: Aerial counts of harbor seals (Pboca vitulina concolor) on ledges along the Maine coast were conducted during the pupping season in 1981, 1986, 1993, 1997, and 2001. Between 1981 and 2001, the uncorrected counts of seals increased from 10,543 to 38,014, an annual rate of 6.6 percent. In 2001 30 harbor seals were captured and radio-tagged prior to aerial counts. Of these, 19 harbor seals (six adult males, two adult females, seven juvenile males, and four juvenile females) were available during the survey to develop a correction factor for the fraction of seals not observed. The corrected 2001 abundance estimate was 99,340 harbor seals. Productivity in this population has increased since 1981 from 6.4% pups to 24.4% pups. The number of gray seals (Halichoerus grypus) counted during the harbor seal surveys increased from zero in both 1981 and 1986 to 1,731 animals in 2001.

    Notes: Capture-recapture techniques have been extensively used to estimate survival rates of Hector's dolphins at Banks Peninsula, but not abundance. We analyzed nine seasons of photo-identification data using a model-fitting approach in the computer program MARK, and then used MARK's estimates of capture probabilities to calculate the abundance of distinctive individuals. We extrapolated these estimates to include unmarked individuals using five seasons of data on the proportion of identifiable individuals in this population, obtained from “random photography.” This capture-recapture approach suggests a 1996 population of about 1,100 (CV = 0.21). This is very similar to the 1997 line-transect estimate of about 900 (CV = 0.28), especially considering that the two techniques do not necessarily measure the same thing. An important advantage of the capture-recapture approach stems from the inherent versatility of photo-ID data. If the sampling design is appropriate, an unbiased abundance estimate can be achieved as a spin-off from work directed at other questions. However, in our view, line-transect estimates are easier to interpret because the sampling design is explicit.

    Notes: We estimated the number of live Australian fur seal pups using capture-markresights, direct ground counts, or aerial photography at all breeding sites following the pupping season of November-December 2002. Pups were recorded at 17 locations; nine previously known colony sites, one newly recognized colony and seven haul-out sites where pups are occasionally born. In order of size, the colonies were Lady Julia Percy Island (5,899 pups), Seal Rocks (4,882), The Skerries (2,486), Judgment Rocks (2,427), Kanowna Island (2,301), Moriarty Rocks (1,007), Reid Rocks (384), West Moncoeur Island (257), and Tenth Island (124). The newly recognized site was Rag Island, in the Cliffy Group, where we recorded 30 pups. We also recorded pups at the following haul-out sites: Cape Bridge-water (7 pups), Bull Rock (7), Wright Rock (5), Twin Islet (1), The Friars (1), He des Phoques (1), and Montague Island (1). In total, we estimate there were 19,819 (SE = 163) live pups at the time of the counts. We discuss trends in pup numbers and derive current population estimates for the Australian fur seal.

    Notes: The echolocation rate and behavior of wild harbor porpoises were studied using a harbor porpoise click detector (POD) deployed close to the bottom at 40 m depth in Scottish waters, UK, April—June 2001. Echolocation variables were compared among four diel phases; morning, day, evening, and night. The echolocation encounter rate, the minimum interclick interval per train, and the proportion of echolocation click trains with a minimum interclick interval below 10 msec were all significantly higher at night than during the day. The variation in echolocation rate implies that porpoises increased their echolocation rate and/or visited the depth of the POD more often at night than during the day. Further, the changes in minimum interclick interval per train suggest that they used their echolocation for foraging or investigating objects at a close range to a higher extent, and acoustically explored the environment at greater distances at night than during the day.

    Notes: Stomach contents from 121 narwhals (Monondon monoceros) harvested in the eastern Canadian High Arctic and West Greenland were used to quantify seasonal changes in feeding activity and prey selection. Stomachs collected from summer harvests were mostly empty with little evidence of recent feeding. Stomachs collected in late fall and winter harvests had considerable amounts of undigested material with evidence of recent feeding. In summer, Arctic cod (Arctogadus glacialis), polar cod (Boreogadus saida), and Gonatus squid spp. constituted the narwhal diet. In fall, Gonatus fabricii was the only prey item observed. In late fall and winter, Greenland halibut (Reinhardtius hippoglossoides) and G. fabricii were the dominant prey items, observed in 51% and 73% of stomachs collected, respectively. Greenland halibut taken by narwhals were on average 39 cm (SD 8) and 556 g (306) and G. fabricii were on average 23 g (15) with mean mantle lengths of 85 mm (24). The low diversiry of prey species indicates narwhals have a restricted diet across all seasons. This study presents the first information on the winter diet of the narwhal and suggests Baffin Bay and Davis Strait are heavily utilized for feeding, in contrast to limited food intake during the summer period.

    Notes: Pinnipeds are often monitored by counting individuals at haul-out sites, but the often large numbers of densely packed individuals at these sites are difficult to enumerate accurately. Errors in enumeration can induce bias and reduce precision in estimates of population size and trend. We used data from paired observers monitoring walrus haul-outs in Bristol Bay, Alaska, to quantify observer variability and assess its relative importance. The probability of a pair of observers making identical counts was < 0.1 for walrus groups with >50 individuals. Mean count differences ranged up to 25% for the largest counts, depending on beach and observers. In at least some cases, there was a clear tendency for counts of one observer to be consistently greater than counts of the other observer in a pair, indicating that counts of at least one of the observers were biased. These results suggest that efforts to improve accuracy of counts will be worthwhile. However, we also found that variation among observers was relatively small compared to variation among visits to a beach so that efforts to account for other sources of variation will be more important.

    Notes: Research into how HR contributes to organisational performance is plentiful yet plagued by challenges. Alongside the ‘black box’ issue between HRM and performance, the time-lag effect and the range of performance indicators applied, the role of the HR department in this relationship is critical although often ignored. A longitudinal case study is presented here that focuses particularly on this issue, and shows a complex picture of improving HR department importance alongside high-level financial performance, but declining employee commitment and morale. The article suggests that the tensions between the rhetoric of HRM strategy, the grim reality of the employee experience and a lack of focus on human capital meant the outstanding financial performance was not sustainable in the longer term. The inherent conflict in serving both management and employees in process-and peopleorientated roles is highlighted.

    Notes: This is an overview of what the authors believe to be every empirical research article into the linkages between HRM and performance published in pre-eminent international refereed journals between 1994 and 2003. The analysis covers the design of the study, including the primary level of analysis and the identity of the respondents; the dominant theoretical framework(s) informing the article; how HRM is conceived and operationalised; how performance is conceived and operationalised; and which control and/or contingency variables are incorporated. Finally, the article examines how each study depicts the so-called ‘black box’ stage between HRM and performance. It reports wide disparities in the treatment of these components, but also some welcome commonalities and indicative trends that point towards a gradual convergence on how future research into this complex relationship might usefully be conducted. The findings are compared with previous reviews of the literature. The analysis should illuminate the ongoing debate about the linkages between HRM and performance, and prove valuable for future research designs.

    Notes: This article focuses on unemployed job-seekers' attitudes towards entry-level jobs in three areas of the service sector – retail, hospitality and call-centre work. The article examines whether job-seekers are reluctant to pursue these opportunities, and provides an analysis of the motives of those ruling out service work. A range of potential barriers is discussed, including the extent to which job-seekers perceive the service economy as offering only so-called ‘McJobs’– low-skilled, low-paid jobs with few opportunities for development. However, the article also focuses on perceived skills mismatches, with some job-seekers arguably over-qualified for entry-level service jobs, while others consider themselves to lack the necessary ‘soft’ skills. The analysis is based on interviews with 220 unemployed people in Glasgow. The article concludes that policy action may be required to encourage job seekers to consider a broader range of vacancies and to provide tailored training in partnership with service employers. On the demand side, service employers must address the need for entry-level positions that offer realistic salaries, decent work conditions and opportunities for progression and development.

    Notes: The evaluation of the impact of changes in reward systems is a common recommendation in the personnel practitioner literature, but little has been written about how and to what extent practitioners themselves evaluate. This article therefore focuses on the activities of HR managers who have introduced new pay systems, not on academic studies of reward system change. Face-to-face interviews were conducted in 15 large, unionised organisations in England between 2000 and 2002. The study found that little formal evaluation of changes in pay and grading systems had been carried out and that managers expressed considerable scepticism about the evaluation process. They relied heavily on informal or anecdotal feedback, and appeared to have little psychological incentive to evaluate. The article suggests explanations for this lack of formal evaluation, drawing on the management decision-making literature, and recommends how changes in reward systems should be evaluated.

    Notes: This article examines the links between employees' satisfaction with HR practices and their commitment to the organisation. It draws on recently collected data to examine these links for three groups of employees: professionals, line managers and workers. Satisfaction with some HR practices appears to be linked to the commitment of all employees, while the link for others varies befuwn the three employee groups. These findings pose a challenge to the universalistic model of HRM and have implications for those seeking to design practices that will improve organisational commitment.

    Notes: This article assesses whether financial participation (profit-sharing and employee share ownership plans) is associated with positive performance outcomes, and whether direct and indirect employee participation complement financial participation in this respect. It also examines whether employee involvement in the design of financial participation afects performance outcomes. The article uses data from a survey of listed firms in Finland, Germany, the Netherlands and the UK. Several outcome measures are used, based on respondents' assessments of the effects of financial participation. Higher participation in equity-based plans, but not in profit-sharing, is found to be associated with more successfil outcomes. None of fhe other forms of employe? pnrticipafion uins found to contribute to the success of financial participation. The results therefore cast some doubt on complementarity between financial and other forms of participation.

    Notes: The last decade of empirical research on the added value of HRM, also known as the ‘HRM and performance’ debate, demonstrates evidence that HRM does matter (Huselid, 1995; Guest et al, 2003; Wright et al, 2003). Unfortunately, the relationships are often statistically weak and the remlts ambiguous. This article reviews and attempts to extend the theoretical and methodological issues in this debate. Its aim is to build an agenda for future research in this area. A brief overview of achievements to date is followed by the theoretical and methodological issues related to what constitutes HRM, what is meant by the concept of perfomzance and the nature ofthe link between these two. In the final section, it is argued that research designs should start from a multi-dimensional concept of performance, including the perceptions ofemployees; and build on the premise of HR systems as an enabling device for a whole range of strategic options. This implies a reversal of the strategy-HRM linkage.

    Notes: This article describes a research project undertaken with the co-operation of the UK's Chartered Institute of Personnel and Development, Derbyshire and Nottinghamshire branch, to investigate members' attitudes to and engagement with ‘continuing professional development’(CPD), and how these correlated with a range of other variables and demographic characteristics. Women held more positive attitudes to the value of CPD than men. The majority of the most popular updating strategies were informal and organisationally located, with less emphasis on courses and qualifications. The most powerful predictor of the perceived value of CPD was professional commitment, while other attitudinal and demographic variables had weaker associations than expected. Valuing CPD did not necessarily translate into participating in it. Implications of this research include guidance for professional institutes on what CPD professionals engage in and why, and what influences this.

    Notes: In considering the development of the HR ‘profession’, there has been little exploration of the role of the professional association. This is particularly true looking across national boundaries, raising questions about the impact and extent of homogeneity of personnel management association activities. It is argued that professional associations have a legitimising role to play in establishing a specialist body of knowledge, regulating practice and providing a source of internal and external identity for practitioners. A recent worldwide survey of personnel management associations found that, although associations are active in these areas, there is a lack of mandatory control and regulation across the profession, diluting the legitimacy accorded by such activities. Association activities were also found to be largely generic across countries, resulting from inter-association collaboration, although different contexts result in different outcomes.

    Notes: Previous research illustrates how managers use the ‘customer’ in the service sector to develop roles and determine requisite skill sets. This article uses the evaluation of a recent workforce modernisation initiative in the NHS to provide insights into the manner in which the patient has played an increasing role in the construction of skills in healthcare. It indicates how public-funded healthcare in the NHS contains similar tensions and contradictions to service work in consumer capitalism. Although the patient is not in a position of authority, the desire of some workers to address fully the physical and psychological needs of the patient (or embodied customer) leads them to develop skills and roles that management may find hard to resource within current budgets.
