环境污染对中枢神经系统损伤的哲学思考

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。     

跨文化适应与应激、应激源研究:中国学生、学者在德国

本文旨在探讨在德国的中国学生／学者跨文化适应与应激源和应激之间的关系。其中,跨文化适应分为总体、人际及学习／工作适应三方面．应激源分为社会和学习／工作两方面,而应激则有文化、心理和生理三个层面。被试为99名在德国的中国留学生及访同学者。研究结果表明：除工作／学习应激与总体适应没有显著负相关之外,应激源与三方面的跨文化适应均显著负相关,回归分析表明了同样的趋势。在应激与跨文化适应的关系上,适应良好的被试应激水平较低。总体适应能够预测文化、生理及生理应激。     

Analysis of response allocation in individuals with multiple forms of stereotyped behavior

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.     

Stressor and Resilience Factors for Lesbians, Gay Men, and Bisexuals Confronting Antigay Politics

When lesbian, gay, and bisexual (LGB) people encounter antigay campaigns and elections, they face explicit and implicit homophobic attacks. In order to understand the points of stress and the bases for resilience in the face of these attacks, we developed a 130-item quantitative survey on the basis of results of an earlier qualitative study. Three hundred, sixteen Colorado LGB people endorsed items representing sources of stress and sources of resilience associated with the campaign for and passage of an antigay referendum. Factor analyses of the results suggested 5 sources of stressors and 5 sources of resilience for LGB persons and their communities.     

The greening of engineers: A cross-cultural experience

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.     

Chile's Environmental Assessments: Contested Knowledge in an Emerging Democracy

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.     

TRANSCENDING OUR BIOLOGY: A VIRTUE ETHICS INTERPRETATION OF THE APPEAL TO NATURE IN TECHNOLOGICAL AND ENVIRONMENTAL ETHICS

“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.     

Mutual Funds Efficiency Measurement under Financial and Social Responsibility Criteria

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.     

Therapeutic Use of Space

ABSTRACT

The project described in this article addresses the therapeutic use of physical space in an outpatient counseling facility. It was theorized that an improved facility environment could be used as a practice tool when working with a vulnerable population. The authors undertook the project with limited time and finances. The process of the change project is discussed in detail in an attempt to encourage other counseling facilities and social service agencies to consider such an effort. Related literature from varied fields is reviewed. The article also relays client and staff feedback regarding the redecorated space and addresses design considerations such as the relative strengths and drawbacks to involving clients and staff in the process.
