Past research suggests that employees, in response to workplace experiences, selectively engage in targeted counterproductive work behaviors (CWBs). Taking a retributive justice and target similarity perspective, we predict that employee perceptions of unfairness from the organization uniquely predict CWB specifically targeted at the organization whereas employee perceptions of supervisory unfairness uniquely predict CWB specifically targeted at the supervisor. We further hypothesized that moral identity‐symbolization would strengthen these target‐similar relationships. Finally, drawing from the sensitivity to mean intentions model, we hypothesized that victim sensitivity would not only strengthen these target‐similar relationships but also lead to cross‐foci effects of multifoci fairness perceptions on targets of CWB. Results from 3 field studies of full‐time employees provided support for most of our hypothesized relationships. 相似文献

This is the second of three articles prepared to explain the Teller County growth management process. As part of an ongoing
growth management process in Teller County, Colorado, opportunities and constraints for development and conservation were
identified. The scenic mountain county faces a number of issues because of growth. The recognition of those issues has resulted
in the goal to direct future growth to the most appropriate and cost-effective places. To determine those places that are
best for new development, thorough ecological inventories were conducted for the entire county as well as for the City of
Woodland Park area. From these inventories, environmentally sensitive areas were identified. The environmentally sensitive
areas were considered constraints in conducting suitability analyses for a variety of potential land uses. The suitability
analyses resulted in the identification of opportunities for future growth in Teller County generally as well as the more
specific Woodland Park planning area. This article, like the other two, is part of a reflective analysis by the planners who
were involved.

An in-situ bioremediation project has been designed and constructed for a site in south-central Kansas just north of Wichita. A pipeline leaked an unknown quantity of refinedfuels in the 1970s. The spill was undetected until hydrocarbons were found in a nearby municipal water supply well. Of concern, from a regulatory perspective, are the alkylbenzene components found in the groundwater, including benzene, toluene, ethylbenzene, and xylene (BTEX). Initial abatement procedures, including free product removal and pumping, had become ineffective. In-situ bioremediation was selected to complete the restoration process. The project emphasizes the need for a strong understanding of the geologic and hydrogeologic conditions prevalent under the site. Site studies were conducted to determine the distribution and mass of the contaminant and the hydraulic regime. Laboratory microbial studies were used to determine the efficacy of nitrate as a primary electron acceptor. Information from site studies was used to design a treatment system tailored to the requirements of the site. The treatment system is designed to deliver the maximum amount of nutrient-enriched water to the contaminated zone while maintaining hydraulic control of the site. 相似文献

This paper discusses common organizational problems that cause inadequate planning and implementation processes of endangered
species recovery across biologically dissimilar species. If these problems occur, even proven biological conservation techniques
are jeopardized. We propose a solution that requires accountability in all phases of the restoration process and is based
on cooperative input among government agencies, nongovernmental conservation organizations, and the academic community. The
first step is formation of a task-oriented recovery team that integrates the best expertise into the planning process. This
interdisciplinary team should be composed of people whose skills directly address issues critical for recovery. Once goals
and procedures are established, the responsible agency (for example, in the United States, the US Fish and Wildlife Service)
could divest some or all of its obligation for implementing the plan, yet still maintain oversight by holding implementing
entities contractually accountable. Regular, periodic outside review and public documentation of the recovery team, lead agency,
and the accomplishments of implementing bodies would permit evaluation necessary to improve performance. Increased cooperation
among agency and nongovernmental organizations provided by this model promises a more efficient use of limited resources toward
the conservation of biodiversity. 相似文献

Long-Term Effects of Changing Land Use Practices on Surface Water Quality in a Coastal River and Lagoonal Estuary 总被引:1,自引:0,他引:1

The watershed of the Neuse River, a major tributary of the largest lagoonal estuary on the U.S. mainland, has sustained rapid
growth of human and swine populations. This study integrated a decade of available land cover and water quality data to examine
relationships between land use changes and surface water quality. Geographic Information Systems (GIS) analysis was used to
characterize 26 subbasins throughout the watershed for changes in land use during 1992–2001, considering urban, agricultural
(cropland, animal as pasture, and densities of confined animal feed operations [CAFOs]), forested, grassland, and wetland
categories and numbers of wastewater treatment plants (WWTPs). GIS was also used together with longitudinal regression analysis
to identify specific land use characteristics that influenced surface water quality. Total phosphorus concentrations were
significantly higher during summer in subbasins with high densities of WWTPs and CAFOs. Nitrate was significantly higher during
winter in subbasins with high numbers of WWTPs, and organic nitrogen was higher in subbasins with higher agricultural coverage,
especially with high coverage of pastures fertilized with animal manure. Ammonium concentrations were elevated after high
precipitation. Overall, wastewater discharges in the upper, increasingly urbanized Neuse basin and intensive swine agriculture
in the lower basin have been the highest contributors of nitrogen and phosphorus to receiving surface waters. Although nonpoint
sources have been emphasized in the eutrophication of rivers and estuaries such as the Neuse, point sources continue to be
major nutrient contributors in watersheds sustaining increasing human population growth. The described correlation and regression
analyses represent a rapid, reliable method to relate land use patterns to water quality, and they can be adapted to watersheds
in any region. 相似文献

A case study of the Yorkshire Derwent (UK) catchment is used to illustrate an integrated approach for assessing the viability
of policy options for reducing diffuse nitrate losses to waterbodies. For a range of options, modeling methods for simulating
river nitrate levels are combined with techniques for estimating the economic costs to agriculture of modifying those levels.
By incorporating spatially explicit data and information on catchment residence times (which may span many decades particularly
in areas of groundwater discharge) a method is developed for efficient spatial targeting of measures, for example, to the
most at-risk freshwater environments. Combining hydrological and economic findings, the analysis reveals that, in terms of
cost-effectiveness, the ranking of options is highly sensitive to both (i) whether or not specific stretches of river within
a catchment are regarded as a priority for protection, and (ii) the criterion of nitrate concentration deemed most appropriate
as an indicator of the health of the environment. Therefore, given the focus under European legislation upon ecological status
of freshwaters, these conclusions highlight the need to improve understanding of mechanistic linkages between the chemical
and biological dynamics of aquatic systems. 相似文献

Trade-offs play pivotal roles in the ecology and evolution of natural populations. However, trade-offs are probably not static, invariant relationships. Instead, ecological factors can shift, alter, or reverse the relationships underlying trade-offs and create critical genotype x environment (G x E) interactions. But which ecological factors alter trade-offs or create G x E interactions, and why (mechanistically) do they do this? We tackle these questions using resource quality as the central ecological factor and a case study of disease in the plankton. We show that clonal genotypes of a zooplankton host (Daphnia dentifera) exhibit a "power-efficiency" trade-off in resource use, where powerful (fast-feeding) host clones perform well on richer algal resources, but more efficient (slow-feeding) clones perform relatively well on poorer resources. This resource-based trade-off then influences epidemiological relationships due to fundamental connections between resources and fecundity, transmission rate (an index of resistance), and replication of a virulent fungal parasite (Metschnikowia bicuspidata) within hosts. For instance, using experiments and dynamic energy budget models, we show that the power-efficiency trade-off overturned a previously detected trade-off between fecundity and transmission risk of hosts to this parasite. When poorer resources were eaten, transmission risk and fecundity were negatively, not positively, correlated. Additionally, poor resource quality changed positive relationships between yield of infectious stages (spores) and host fecundity: those fecundity-spore relationships with poor food became negative or nonsignificant. Finally, the power-efficiency trade-off set up an interaction between host clone and resource quality for yield of fungal spores: powerful clones yielded relatively more spores on the better resource, while efficient clones yielded relatively more on the poorer resource. Thus, the physiological ecology of resource use can offer potent, mechanistic insight linking environmental factors to epidemiological relationships. 相似文献

The capillary electrophoresis (CE) method combined with a sequential extraction was applied to determine the distribution of Fe, Zn, Cu, Mn and Cd in urban ambient air PM2.5 samples. PM2.5 was collected on Teflon filters with dichotomous sampler, and the modified extraction procedure following the BCR leaching procedure was used to chemically fractionate metals into "easily exchangeable" with water, "acid extractable" with 0.11 mol/l acetic acid, "reducible" with 0.1 mol/l hydroxylamine hydrochloride acidified to pH 2.0 with nitric acid, and "oxidisable" with oxidation by 8.8 mol/l hydrogen peroxide (H2O2) followed by extraction with 1.0 mol/l ammonium acetate. Based on the obtained results it was concluded that the application of the studied methodology provides chemical fractionation data that reflect the general sources and potential health hazards of the studied metals. 相似文献

Vogel, Richard M., Chad Yaindl, and Meghan Walter, 2011. Nonstationarity: Flood Magnification and Recurrence Reduction Factors in the United States. Journal of the American Water Resources Association (JAWRA) 47(3):464‐474. DOI: 10.1111/j.1752‐1688.2011.00541.x Abstract: It may no longer be reasonable to model streamflow as a stationary process, yet nearly all existing water resource planning methods assume that historical streamflows will remain unchanged in the future. In the few instances when trends in extreme events have been considered, most recent work has focused on the influence of climate change, alone. This study takes a different approach by exploring trends in floods in watersheds which are subject to a very broad range of anthropogenic influences, not limited to climate change. A simple statistical model is developed which can both mimic observed flood trends as well as the frequency of floods in a nonstationary world. This model is used to explore a range of flood planning issues in a nonstationary world. A decadal flood magnification factor is defined as the ratio of the T‐year flood in a decade to the T‐year flood today. Using historical flood data across the United States we obtain flood magnification factors in excess of 2‐5 for many regions of the United States, particularly those regions with higher population densities. Similarly, we compute recurrence reduction factors which indicate that what is now considered the 100‐year flood, may become much more common in many watersheds. Nonstationarity in floods can result from a variety of anthropogenic processes including changes in land use, climate, and water use, with likely interactions among those processes making it very difficult to attribute trends to a particular cause. 相似文献
