Why Not Interfere With Nature?

Advocates of an environmental ethic frequently claim that what makes an ethical theory truly and uniquely environmental is its commitment to the principle that environmental wholes such as species, ecosystems, and biotic communities are morally considerable. The prevailing view is that our primary duty towards these wholes is to respect their integrity, stability, and beauty, and that the best way to do this is to leave them alone, not interfere with them, and let nature follow its own course. But is that correct? Why should be refrain from interfering with nature? There are two ways an environmentalist might try to justify an exceptionaless, prima facie principle of noninterference. First, she might claim that there is a contingent but universal connection between human interference and ecosystemic harm. There is also an epistemic variant of this view. When faced with a decision concerning whether to interfere with an ecosystem, there will always be overwhelming reasons for thinking that interference will be harmful, regardless of the specific circumstances. Send, there might be some conceptual connection between interference and harm to ecosystems. For example, if the well-being of an ecosystem is identified with its wildness, and wildness is understood as the absence of human intervention or manipulation, then any human interference necessarily detracts from an ecosystem's wildness and thereby has a detrimental effect on its well-being. In this paper I examine these justifications in detail and argue that none can support an exceptionaless principle of noninterference.     

青少年学生疏离感及其发展的研究

本研究采用<青少年学生疏离感量表》对重庆市和兰州市的1502名青少年学生进行调查,结果表明:青少年学生在生活环境疏离感和压迫拘束感上的平均分相对较高;各学生群体在社会疏离感、人际疏离感和总体疏离感之间的差异,主要体现在年级和地区的交互作用上,而环境疏离感的差异主要体现在性别和片区的交互作用上。各群体疏离感的差异主要表现在年级和片区之间;青少年学生的疏离感大体呈现出三个阶段的发展趋势,即是:初中阶段发展比较平稳,没有大的起伏变化;高中和大学阶段都是从低到高,再从高到低的倒“V”字型发展变化趋势。     

Neuropsychological Functioning in Danish Gulf War Veterans

Research has shown that Danish Gulf War (GW) veterans reported a significantly higher prevalence of neuropsychological symptoms than did military controls 6 years after GW deployment. To explore the possible central nervous system determinants of these complaints, neuropsychological tests were administered to stratified, random samples of the Danish cohort of 916 GW-deployed veterans and 236 non–GW-deployed participants. Multivariate analyses of covariance were used to analyze neuropsychological test outcomes among the 215 male participants (143 GW-deployed and 72 non–GW-deployed soldiers). No significant differences in neuropsychological test performances were found between the GW-deployed and non–GW-deployed groups. Troops deployed to the GW reported significantly more mood complaints (i.e., fatigue and confusion) than their nondeployed counterparts. Because they were assigned to the Gulf region during the postcombat phase, Danish GW soldiers differed from the majority of American GW-deployed troops in military assignments and possible toxicant exposures.     

Cognitive Functioning in Treatment-Seeking Gulf War Veterans: Pyridostigmine Bromide Use and PTSD

Gulf War (GW) deployed veterans have reported health symptoms since returning from the war that suggest dysfunction of the central nervous system (CNS). These symptoms include memory and concentration difficulties, fatigue, and headaches. Leading hypotheses for the etiology of these cognitive complaints include psychological factors and/or exposures to chemicals with neurotoxic properties. In this study, cognitive functioning was compared in treatment-seeking GW-deployed veterans and a treatment-seeking non–GW-deployed veteran control group. Results indicated that GW-deployed veterans performed significantly worse than the comparison group on tests of attention, visuospatial skills, visual memory, and mood. GW-deployed veterans who reported taking pyridostigmine bromide (PB) performed worse than GW-deployed veterans without PB use on executive system tasks. Treatment-seeking GW-deployed veterans with diagnoses of posttraumatic stress disorder (PTSD) did not differ on cognitive test measures compared with GW-deployed veterans without PTSD. No interaction effect of PTSD and PB use was found.     

西方环境伦理学的整体主义诉求与困惑--现代系统整体论的启示

在西方环境伦理学中，生态中心论具有强烈的整体主义诉求。认为，人类只是自然整体中的一个成员和后来者；生态系统的价值具有内在性和优先性；人类对自然生态系统负有直接的、终极的道德责任和义务。这些观点受到一些学者的质疑。系统整体论理念和复杂性研究对生态系统与人类的关系，系统的目的性，整体的价值等问题提供了一定的支持和启示。     

Protest Against Waste Contamination in the ‘Land of Fires’: Psychological Antecedents for Activists and Non‐activists

The ‘Land of Fires’ is a district in Italy characterized by illegal waste disposal, waste burning, and citizen protests over contamination. This study investigates the relevance of several psycho‐social factors that predict citizens' intention to protest, taking into account different research traditions. In addition, we hypothesize the effect of protest antecedents to be moderated by past participation behaviour (i.e. the level of activism). Hence, our study is a first attempt to explore the effect of protest antecedents as a function of the individual level of activism through a cross‐sectional survey study (N = 306). The results show significant effects of collective identity, sense of injustice, costs of protest, and perceived risk (cognitive dimension) on intention to protest. The effects of collective efficacy and perceived risk (affective dimension) are moderated by participants' level of activism, and these effects are significant only for non‐activists. The relevance of this new approach is discussed, as well as practical implications and possible further developments. Copyright © 2016 John Wiley & Sons, Ltd.     

Cultural worldviews and climate change: A view from China

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.
