The goal of this study is to show the relevance of organizational justice principles in interventions to prevent psychosocial risks. Following an introduction identifying organizational justice as a predictor of health and quality of work life, we illustrate its application to a diagnosis and an intervention for hospital staff. The responses of 685 employees to a questionnaire identified a lack of support and justice by managers; thus, sensitivity to organizational justice was incorporated into a training program on management and psychosocial risks. A quasi-experiment in which hospital staff participated revealed a beneficial effect of the manager training on justice perceptions of the staff, confirming in part our hypotheses. The illustration in our study of the benefits of using justice principles in manager training offers new perspectives for promoting quality of life at work and reducing psychosocial risks.  相似文献

对426名大学生进行问卷调查,考察了感知环境不确定性对认知变化的影响,环境扫描行为的中介作用以及认知闭合需要与认知需要对两阶段中介模型的调节作用。结果发现:(1)感知环境不确定性能够正向预测认知变化水平,并且环境扫描行为的两个维度都起到中介作用;(2)认知闭合需要能够负向调节中介模型的前后两个阶段;(3)认知需要对环境扫描有直接正向作用,并且对关注程度的促进更大,但是负向调节扫描频率和认知变化之间的关系。  相似文献

随着工农业生产的迅速发展,全球环境污染日趋严重,由此引发了环境污染对健康影响的思考。环境污染问题从各个方面影响着人类的健康,尤其是它对人类中枢神经系统地损伤已成为人们对健康关注的重点之一。本文运用矛盾自然观的哲学观点,对环境污染对中枢神经系统的损伤做出阐述和几点思考。  相似文献

Three experiments were conducted to evaluate response allocation of stereotypy during free-operant and restricted-operant conditions. Five children with autism or related developmental disabilities participated in at least one and up to three of the experiments. In Experiment 1, the stereotypic response that emerged as most probable during a free-operant phase was restricted, and response allocation was again evaluated. The results for 3 participants showed that restricting the high-probability response was correlated with covarying reductions in a nontargeted stereotypy. In Experiment 2, the effect of environmental enrichment on response allocation was evaluated. One participant reallocated behavior to appropriate object manipulation, 1 participant showed no change in behavior, and a 3rd participant reallocated behavior to object manipulation only when the putative stimulus products of the object manipulation matched those of stereotypy. In Experiment 3, additional interventions were implemented to promote response reallocation. Results showed that both response restriction and reinforcement for object manipulation decreased stereotypy and increased object manipulation. Collectively, the results of these experiments point to a need for complex evaluations of interventions for stereotypy.  相似文献

Experience with a group of mechanical engineering seniors at the University of Colorado led to an informal experiment with engineering students in India. An attempt was made to qualitatively gauge the students’ ability to appreciate a worldview different from the standard engineering worldview—that of a mechanical universe. Qualitative differences between organic and mechanical systems were used as a point of discussion. Both groups were found to exhibit distinct thought and behavior patterns which provide important clues for sensitizing engineers to environmental issues in future educational initiatives. Cross-cultural and global dimensions of these initiatives are discussed.  相似文献

Abstract

In 1990, Chile transitioned to democracy after 17 years of military rule. The new democracy built the country's first environmental institutions and began efforts to revitalize science, among them attempts to connect scientific expertise to public decision-making. Just over a decade into these efforts, conflicts over the environmental impacts of large industrial projects began to multiply. These environmental conflicts were often also credibility contests, where the authority of science to speak to public issues was contested. Two such conflicts, a gold mine called Pascua Lama and a hydroelectric project called HidroAysén, enrolled several scientific teams, yet in each case the state made its final decision on each project autonomously from science. Though some scientists became central participants in each conflict, carving out for themselves access to needed resources that they used to practice ever-narrower forms of science, their credibility was called into question by many of their scientific colleagues. Chile's scientific community fractured over how to define credible science. Divisive and decisive issues included the source of funding, ethics, access to resources, and being local. Although some scientists and non-scientists used boundary work to try to affirm the authority of science, no stable map of scientific credibility resulted from these efforts. Chile's new democracy is more plural than its recent military dictatorship but still lacks adequate spaces in which to negotiate what counts as credible science. These experiences highlight the need to better understand how science fares through regime transitions and what it contributes to emerging democracies.  相似文献

“Arguments from nature” are used, and have historically been used, in popular responses to advances in technology and to environmental issues—there is a widely shared body of ethical intuitions that nature, or perhaps human nature, sets some limits on the kinds of ends that we should seek, the kinds of things that we should do, or the kinds of lives that we should lead. Virtue ethics can provide the context for a defensible form of the argument from nature, and one that makes proper sense of its enduring role in debates concerning our relationship to technology and the environment. However, the notion of an ethics founded upon an account of the essential features of human nature is controversial. On the one hand, contemporary biological science no longer defines species by their essential characteristics, so from a biological point of view there just are no essential characteristics of human beings. On the other hand, it might be argued that humans have, in some sense, “transcended our biology,” so an understanding of humans as a biological species is extraneous to ethical questions. In this article, I examine and defend the argument from nature, as a way to ground an ethic of virtue, from some of the more common criticisms that are made against it. I argue that, properly interpreted as an appeal to an evaluative account of human nature, the argument from nature is defensible with the context of virtue ethics and, in this light, I show how arguments from nature made in popular responses to technological and environmental issues are best understood.  相似文献

With the rising interest in the field of trauma research, many Institutional Review Boards, policymakers, parents, and others grapple with the impact of trauma-research participation on research participants' well-being. Do individuals who participate in trauma-focused research risk experiencing lasting negative effects from participation? What are the potential benefits that may be gleaned from participation in this work? How can trauma research studies be designed ethically, minimizing the risk to participants? The following review seeks to answer these questions. This review indicates that most studies in this area have found that only a minority of participants experience distress when participating in trauma-focused research. Furthermore, these negative feelings tend to dissipate quickly over time, with the majority of participants self-appraising their participation as positive, rewarding, and beneficial to society. Design characteristics that may serve to minimize participants' risk of experiencing distress are discussed, as well as implications for public policy and future research.  相似文献

Socially responsible investors pursue financial as well as nonfinancial goals. Whereas the role of financial criteria in investment decisions is well understood, much less is known on the influence of social responsibility considerations. This work seeks to integrate both dimensions within a data envelopment analysis framework consistent with second‐order stochastic dominance efficiency. We compare the performance of conventional versus socially responsible mutual funds on an empirical data set. Our data do not support the conjecture that conventional mutual funds exhibit superior overall performance. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
