The Environmental Protection Agency developed the Clean Air Interstate Rule (CAIR) to minimize sulfur dioxide and nitrogen oxide emissions from power plants and prevent pollution spillover into downwind states. While observers of CAIR claim success in the reduction of air pollution, our innovative multivariate statistical analysis based on spatial and facility‐level panel data finds mixed results concerning the rule's effectiveness. On the one hand, we find that CAIR facilities are associated with increases in the reduction rate of pollution compared to non‐CAIR facilities. However, the evidence suggests that sulfur dioxide levels decreased in CAIR‐mandated facilities before the actual implementation of the program. Additionally, on the one hand, CAIR facilities in the interior of states are associated with slower pollution reduction rates than those on the border. However, this difference in reduction rate does not change dramatically before or after the adoption or implementation of this rule. This suggests that the CAIR program was ineffective in targeting specific facilities most likely to contribute to interstate pollution. We conclude that while CAIR spurred the electrical utility industry to reduce air pollution, some of these reductions occurred before the actual implementation of the program. More substantially, gains in interstate spillover pollution did not occur by targeting specific facilities most likely to spillover but rather through the overall reduction of air pollution in the eastern states.  相似文献

The novel Cement Garden written by Ian McEwan shows a kind of feature as wasteland in ecological criticism. From the perspective of natural ecology, the natural environment in the novel is very bad, which is mainly reflected in the remoteness of geographical location, and the filth and corruption of the living environment. From the perspective of social ecology, the relationship between the characters has been seriously distorted, mainly reflected in the loss of the bond of love. From the perspective of spiritual ecology, the characters in the novel have different neurological personalities, which lead to their inner imbalance.  相似文献

酒店服务工作环境对员工在心理上的边缘化和行为上的离职倾向有显著负影响。员工在性别、婚姻、学历和工作年限上的差异对员工边缘化和离职倾向也影响显著,而年龄、职位等方面则对边缘化和离职倾向影响不明显。应从打造工休皆宜的硬件环境、构建公正合理制度环境、营造和谐关爱的人文环境和建设愉悦向上的心理环境等方面提升酒店服务工作环境的建设,以期通过对酒店服务工作环境的改善来防范员工边缘化和离职倾向的产生,从而为酒店维持员工队伍的稳定进行新的探索。  相似文献

Abstract

This article proposes an original reading of Father (1931) and Fräulein Schmidt and Mr Anstruther (1907), two texts by Elizabeth von Arnim that centre on a young single woman. It will examine how female autonomy is spatially imagined in the form of a garden and poses significant challenges to the patriarchal societies presented in the texts. Many scholars have detailed the recurring motif of the garden in Elizabeth and Her German Garden (1898) and The Solitary Summer (1899). The two texts this article addresses were published later than those that have been discussed in relation to the garden, and signal a move away from the married female towards an examination of the independent or single female. Significantly, they disrupt the traditional ‘marriage plot’ novel by tracing two single women’s movement into the garden as a retreat from the societies in which they live. In both texts, von Arnim presents a distinctively beautiful, transcendent garden experience for her female protagonists that contrasts with the oppressive expectations placed on them by urban society. These texts turn on dichotomies—city/country, built/organic environments, repression/freedom—to expose the central characters’ repression and their attempts to gain some degree of independence. Each central character experiences joy as a result of her interaction with the organic environment and the power the protagonist exercises over this space.  相似文献

The mainstream environmental movement has tended to accept the continuation of capitalism and the growth economy. A de-materialization is hoped to follow from limits on the use of natural resources. Eco-Marxists have opposed this strategy, claiming environmental problems are intrinsic to capitalism. More recently a tendency which I will call “radical reformism” has been gaining strength. Radical reformists argue that a growth economy is not compatible with environmental limits. They look to regulate capitalism to prevent growth. The overall intention is for a peaceful transition within a broadly capitalist economy. The eco-Marxist critique of mainstream environmentalism can also be applied to radical reformism. While radical reformists may have some answers to this critique, these answers bring further problems.  相似文献

We investigate how Eastern Ohio landowners affected by the recent boom in high‐volume hydraulic fracturing (HVHF) view the industry and the factors that affect their attitudes. Our unique sample almost exclusively contains individuals whose land is under lease for and/or experiencing HVHF. Nation‐ and state‐wide surveys that investigate HVHF attitudes tend to find nearly even splits between opposed and supportive respondents, whose views are strongly influenced by political partisanship. These trends largely do not manifest among Eastern Ohio landowners, for whom personal experiences with HVHF crucially influence attitudes. Most respondents support HVHF and say it has benefited their community economically. Political partisanship does not significantly impact HVHF views. Contrary to arguments in the literature that economic considerations drive variation in support for HVHF, landowners’ support for the industry also appears influenced by perceptions of its environmental and infrastructure impacts. Environmental concerns appear to more powerfully shape attitudes than economic benefits.  相似文献

Solving environmental problems on a regional scale demands joint efforts by multiple stakeholders, but coordinating such efforts can be difficult in complex governance systems. In this article, we combine the literature in Adaptive Governance with the Ecology of Policy Games (EPGs) framework to enhance our understanding of how complex governance systems react to environmental focusing events. We study the EPGs in the Paraná River delta in Argentina following widespread fires caused by slash‐and‐burn practices in 2008, and analyze how new forums created to address the consequences of this event differ from the forums created prior to the event in terms of their capacity to attract stakeholders and to provide higher interconnectivity to the whole governance system. Furthermore, we offer an initial evaluation of the Comprehensive Strategic Plan for the Conservation and Sustainability of the Paraná River delta, the main forum in the EPGs created to address the negative consequences of the focusing event. Finally, we discuss the implications of our findings for the study of complex governance systems where stakeholders are able to address the management of natural resources at a regional scale.  相似文献

This analysis explores the role of city‐level and state‐level variables to explain why some cities make more progress on climate‐related policy implementation than others. Using multilevel modeling, we find little support for the influence of state factors on local government leadership among the 812 cities in the dataset, but local government institutional and community variables are strongly associated with climate policy initiatives. We argue for a rethinking of the notion of the limited and constrained city and suggest that, in the realm of climate protection and environmental policy, cities are leading a bottom‐up federalism. Moreover, where some political analysts and scholars have argued that climate protection and environmental policies may not be economically rational for cities to pursue, we theorize that cities are acting locally to further their self‐interest in an increasingly global economy.  相似文献

This essay reviews a new edited volume entitled Does Regulation Kill Jobs? It concludes that this book brings much needed data and realism to the debate about jobs and the environment, showing that government regulation generally has minor impacts on employment. This essay focuses much of its attention on the suggestion, discussed by several of the contributors to this book, that cost–benefit analysis should include a dollar value representing an estimate of the value of employment changes a proposed regulation might cause. It discusses concerns about double counting, ex ante estimates of employment impacts, monetization of the value of employment impacts, and potentially misleading asymmetric analysis.  相似文献
