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

We discuss Professor Jeffrey Church's report to the EuropeanCommission in 2004 on the effects of vertical restraints andmergers. Although thorough and accurate, the report could bemisinterpreted by practitioners, as it does not emphasize thatmarket power is only a necessary condition for harm to competition,and that most vertical mergers that present the possibilityof competitive harm also present economic efficiencies thatare intrinsic to the integration.  相似文献

How realistic are democratic-governance strategies that emphasize local governance as a key component? Using Nigeria’s experience in local government and primary health care in the 1980s and 1990s as a case example, the article finds there were substantial shortfalls in local participation and program performance. These were caused by problems in the local political environment and local institutional design, in the national policy environment (particularly in the funding system), and by the stresses of structural adjustment, resource shortfalls, the natural physical environment, and weak leadership. These combined to create poor and inappropriate reward structures and lack of accountability. However, even though the Nigerian case was not successful, most of the specific problems that hurt it are remediable through policy changes at the national level. Several of these were under consideration at the time of the coups of 1992 and 1993.  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

Constitutional engineering to overcome ethnoregional cleavagesis being put to a severe test on Cyprus, where Greek and Turkishcommunities haltingly endeavor to salvage a divided state Threeyears after independence in 1960, the attempt to govern throughfunctional federalism ended in civil war. Intervention by Greeceand Turkey in 1974 resulted in a de facto partitioning of therepublic into two ethnically homogeneous areas. Under UnitedNations auspices, communal elites bargain for a consociationalsettlement, balancing national autonomy and individual rights.The solution requires international safeguards guaranteeinga new constitution and providing for "free cities" under a bicommunaladministration. Failure of the international community to actwill lead to a partitionist solution as manifested by a growingacceptance of Turkish Cypriot statehood.  相似文献
