In 1990, the state of California passed the pioneering mandate on zero emission vehicles (ZEV). This technology‐forcing regulation is aimed at improvement of air quality and protection of public health from the adverse effects of air pollutants from automobiles. Facing severe opposition from the auto industry, the mandate has been revised a number of times, most recently in 2003, whereby the requirement for ZEVs have been made to align with the pace of technology development. Review of strategies used in implementation of the mandate has revealed greater emphasis on the economic incentives for rather than on environmental merits of ZEVs. Using prospect theory as the framework for analysis, the reasons have been explored. The findings of the study help us to understand how decisions are made with respect with to deviations from a mental anchor point and through the process of evaluation of losses and gains.  相似文献

Abstract: Historically, the concept of career public service has received remarkably little attention in Canada. Career public service is, however, a central theme in the recent Public Service 2000 white paper on renewal of the federal public service. The challenge is to decide the extent to which the public service should adhere to the major principles of career public service relating to political neutrality, merit, open versus closed competitions, and career planning. There are significant barriers to achieving these principles, including conflict between some of the principles themselves. The extent to which career service will be achieved depends largely on the degree to which the vision of Public Service 2000 is realized. It is a vision of a new public service culture that is results-oriented and client-oriented and that is based on the precepts of service, innovation, people, and accountability. Among the obstacles to successful implementation of this vision are resistance by public service unions, lack of understanding about the magnitude of the commitment required to create a new public service culture, and the possible lack of political will to implement the white paper's proposals. Among the means by which the federal government can enhance the prospects for career service are a renewal of commitment to career service, including the allocation of more resources to career planning and development, and greater sensitivity to the threat of undue politicization of the public service. Sommaire: Historiquement, au Canada, le concept d'une fonction publique de carrière a bien peu retenu I'attention. Mais récemment, un livre blanc consacré au renouveau de la fonction publique, intituléFonction publique 2000, en a fait son thème central. L'enjeu, c'est de décider dans quelle mesure la fonction publique devrait adhérer aux principes fondamentaux d'une fonction publique axée sur des fonctionnaires de carrière, en ce qui concerne la neutralité politique, le mérite, les nominations en système ouvert ou fermé, et la planification de carriÈre.  相似文献

This paper gives the author's impressions on the following aspects of justice: desert, equity, equality, need, and intergenerational equity. The author concludes that these different aspects cannot be reconciled but instead must be compromised. An example of such a compromise is provided by a discussion of welfare reform. The author claims that rights are correlative with duties, and that asserting the former has little meaning without specifying the latter. He then discusses justice toward groups rather than individuals. He proposes that maintaining cultural variety in the presence of a homogeneous superculture is a major problem of the contemporary world. The paper concludes with a discussion of various forms of power, particularly the integrative power that people acquire over each other by virtue of ties of loyalty and identity.  相似文献

This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used.  相似文献
