The link between the interpersonal stressor of workplace mistreatment and objective measures of performance is often overlooked in organizational research. In order to fill this research gap, we examined the unique and combined effects of two sources of incivility (customer and coworker) on objective sales performance and withdrawal behaviors (absenteeism and tardiness). We hypothesized that coworker and customer incivility would interact to predict reduced performance and increased withdrawal, using the conservation of resources model to support our hypotheses. We surveyed 120 bank tellers regarding experienced incivility and obtained performance and withdrawal data spanning a period of several months following the survey. The data indicated that coworker and customer incivility did interact to predict decreased sales performance and increased absenteeism, supporting the majority of our proposed hypotheses. Theoretical and practical implications of the findings and future directions are discussed. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Consumption of inorganic arsenic in drinking water at high levels has been associated with chronic diseases. Risk is less clear at lower levels of arsenic, in part due to difficulties in estimating exposure. Herein we characterize spatial and temporal variability of arsenic concentrations and develop models for predicting aquifer arsenic concentrations in the San Luis Valley, Colorado, an area of moderately elevated arsenic in groundwater. This study included historical water samples with total arsenic concentrations from 595 unique well locations. A longitudinal analysis established temporal stability in arsenic levels in individual wells. The mean arsenic levels for a random sample of 535 wells were incorporated into five kriging models to predict groundwater arsenic concentrations at any point in time. A separate validation dataset (n = 60 wells) was used to identify the model with strongest predictability. Findings indicate that arsenic concentrations are temporally stable (r = 0.88; 95 % CI 0.83–0.92 for samples collected from the same well 15–25 years apart) and the spatial model created using ordinary kriging best predicted arsenic concentrations (ρ = 0.72 between predicted and observed validation data). These findings illustrate the value of geostatistical modeling of arsenic and suggest the San Luis Valley is a good region for conducting epidemiologic studies of groundwater metals because of the ability to accurately predict variation in groundwater arsenic concentrations. 相似文献

Community gardens and sustainable land use planning: A case-study of the Alex Wilson community garden 总被引:1,自引:0,他引:1
An analytical account of the history and aspirations of the Alex Wilson Community Garden in Toronto provides an ideal opportunity to examine the connections between two typically distinct enterprises: ecological restoration and community gardening. These are both important contemporary ecological movements, but are rarely combined in a single project that demonstrates the principles of sustainable land use and community planning. The garden is named in memory of Alex Wilson, a landscape designer, community activist and writer who worked and lived in Toronto, Canada. During his life, Wilson established a community garden which was eventually replaced by conventional urban development. After his death in 1993, friends and colleagues decided to honour his memory by establishing a permanent community garden in his name. The Alex Wilson Community Garden opened to the public in June 1998. The case-study explores how the garden reflects Wilson's work by linking community gardening and ecological restoration. These features are unified in Wilson's work as a means of nurturing relationships between people, communities and the landscape—relationships that are social, economic and ecological. In his book,The Culture of Nature: North American landscape from Disney to the Exxon Valdez (1991), Wilson argues that “we must build landscapes that heal and empower, that make intelligible our relations with each other and the natural world”. The Alex Wilson Community Garden illustrates in a practical manner the principles espoused by Wilson through its design, planning and functioning. The case-study reports on the innovative approach to landscape design taken in the garden, which reconstructs the natural and cultural history of southern Ontario, featuring lake-shore, agricultural and woodland sections. The garden has been planted exclusively with native plant species, and is expected to have a positive impact on local biodiversity. The planning process which led up to the design of the garden was participatory in nature, encompassing friends and colleagues of Alex Wilson, local residents and city planning officials, and made use of a number of planning tools not usually applied in an urban setting, including the granting of a conservation easement. The garden also addresses emerging issues associated with globalisation and large cities by providing food production opportunities for local residents, including a low-income housing complex and a nearby drop-in centre. Ecological monitoring and assessment of the naturalised area will be carried out by local residents. 相似文献

Studies report that between 6 per cent and 29 per cent of survivors of sexual violence in eastern Democratic Republic of the Congo (DRC) are rejected by their families and communities. This research project was designed to provide insights into survivors' experiences of stigmatisation and rejection. Surveys were conducted with 310 women as they sought psychosocial services in eastern DRC. In total, 44.3 per cent of women reported suffering rejection after sexual violence. The majority of women felt that their status in the household (58.0 per cent) and community (54.9 per cent) diminished after rape. The odds of rejection were greater among women reporting ongoing displacement, pregnancy owing to sexual violence, worsening family relations, and diminished community status. This work highlights the extremely high levels of loss associated with the war in eastern DRC, particularly among survivors of sexual violence. The rejection of a survivor of rape has concrete and devastating psychosocial consequences. 相似文献

In 2004–05, Niger suffered a food crisis during which global attention focused on high levels of acute malnutrition among children. In response, decentralised emergency nutrition programmes were introduced into much of southern Niger. Child malnutrition, however, is a chronic problem and its links with food production and household food security are complex. This qualitative, anthropological study investigates pathways by which children are rendered vulnerable in the context of a nutritional 'emergency'. It focuses on household-level decisions that determine resource allocation and childcare practices in order to explain why practices apparently detrimental to children's health persist. Risk aversion, the need to maintain self-identity and status, and constrained decision making result in a failure to invest extra necessary resources ingrowth-faltering children. Understanding and responding to the social context of child malnutrition will help humanitarian workers to integrate their efforts more effectively with longer-term development programmes aimed at improving livelihood security. 相似文献

Participatory modeling is increasingly recognized as an effective way to assist collective decision-making processes in the
domain of natural resource management. This article introduces a framework for evaluating projects that have adopted a participatory
modeling approach. This evaluation framework—known as the “Protocol of Canberra”—was developed through a collaboration between
French and Australian researchers engaged in participatory modeling and evaluation research. The framework seeks to assess
the extent to which different participatory modeling initiatives not only modify perceptions among and interactions between
participants, but also contribute to collective decision-making. The article discusses the development of the framework and
it’s application to three case-studies, two from Australia and one from the Pacific Island of the Republic of Kiribati. The
article concludes with some comments for future use of the framework in a range of participatory modeling contexts. 相似文献

Discharge from the Great Barrier Reef Catchment (GBRC) is considered the second most serious threat to the Great Barrier Reef, Australia. Utilising principal component analysis (PCA) and cluster analysis (CA), this research aimed to assess the variability and co-variation of 28 water basins (WBs) within the GBRC, in order to improve the institutional arrangements and regulation of water quality and increase collaboration horizontally between management organisations, and vertically between government tiers. Water basin variability was measured by nine variables: size (ha), population, agricultural land use (ha), number of major water storages, major rivers and major towns, total nitrogen exported (T/yr), total phosphorus exported (T/yr) and herbicide use (ha). The Fitzroy WB, with PC scores of 7.0081, 2.2897 and ?1.6504, was identified as the most dissimilar and therefore needing to be managed differently. Many WBs within the same regions were very dissimilar to each other, indicating that current management practices, based largely on geographic location, are unlikely to be the most efficient and effective. Instead, managing groups of WBs with similar geo-political properties (determined by the CA) could be more effective and efficient. Coordination and collaboration are key to successful ecosystem based management, therefore managing similar WBs together through inter-NRM (natural resource management) agreements, irrespective of their geographical location, facilitates management bodies building strong, cooperative working relationships. 相似文献

Reintroduction of imperiled native freshwater fish is becoming an increasingly important conservation tool amidst persistent anthropogenic pressures and new threats related to climate change. We summarized trends in native fish reintroductions in the current literature, identified predictors of reintroduction outcome, and devised recommendations for managers attempting future native fish reintroductions. We constructed random forest classifications using data from 260 published case studies of native fish reintroductions to estimate the effectiveness of variables in predicting reintroduction outcome. The outcome of each case was assigned as a success or failure on the basis of the author's perception of the outcome and on whether or not survival, spawning, or recruitment were documented during post‐reintroduction monitoring. Inadequately addressing the initial cause of decline was the best predictor of reintroduction failure. Variables associated with habitat (e.g., water quality, prey availability) were also good predictors of reintroduction outcomes, followed by variables associated with stocking (e.g., genetic diversity of stock source, duration of stocking event). Consideration of these variables by managers during the planning process may increase the likelihood for successful outcomes in future reintroduction attempts of native freshwater fish.
