China's rapidly growing motor vehicle fleet is changing the makeup of its urban atmosphere. While the two major problem pollutants historically have been particulates and sulfur dioxide, the growth in the number of automobiles has generated substantially increased levels of nitrogen dioxide (NO2). This paper examines and values the mortality health effects (reduced premature deaths) from cleaning up these three pollutants. Findings indicate that valued gains from reduced air pollution mortality can average 3% of a city's GDP. Moreover, the growing auto fleet may generate a ten-fold increase in NO2-based mortality costs and offset other, ongoing cleanup efforts in many Chinese cities. Specifically, the paper explores how the increasing number of automobiles might diminish or offset environmental cleanup activities focused upon particulate and sulfur dioxide pollution.  相似文献

Taiwan is a revisionist power. Its independence movement challenges a vital status-quo interest of mainland China's opposition to a de jure Taiwan declaration of independence and maintaining, however ambiguously, Taiwan's commitment to the ‘one-China’ formulation. Why is it that a small and vulnerable island off the coast of a great power has continued to challenge the vital interest of that great power and risk war? Adopting a ‘levels of analysis’ approach to Taiwan's mainland policy, this paper addresses this question by examining four prevalent explanations for Taiwan's revisionist diplomacy: (1) the mainland deterrent is ineffective, reflecting Taiwan doubts about either mainland capabilities or mainland resolve to wage a retaliatory war; (2) in an example of the security dilemma in alliance politics, US commitment to Taiwan, although aimed at deterring PRC use of force, encourages Taiwan to challenge the status quo because the Taiwan leadership is confident of US intervention and US ability to defend Taiwan; (3) because of the development of a ‘Taiwan identity’ and of corresponding domestic political pressures, the Democratic Progressive Party has been compelled to adopt a pro-independence policy; (4) Chen Shui-bian has a personal commitment to Taiwan independence and has been willing to challenge the mainland's interest in one-China, despite risk of heightened conflict and regardless of domestic political considerations.  相似文献

Inside Collaborative Networks: Ten Lessons for Public Managers   总被引:4,自引:1,他引:4  
This paper offers practical insights for public managers as they work within interorganizational networks. It is based on the author's empirical study of 14 networks involving federal, state, and local government managers working with nongovernmental organizations. The findings suggest that networks are hardly crowding out the role of public agencies; though they are limited in their decision scope, they can add collaborative public value when approaching nettlesome policy and program problems.  相似文献

Hurricane Katrina revealed a lack of preparedness in disaster management networks covering the New Orleans area. This paper focuses on the operation of networks in preparing to evacuate residents in advance of a major disaster. There are two cases: the relatively successful evacuation of residents who left by private conveyance and the widely publicized failure to provide for those who could not or would not leave on their own. We trace the actions and inactions of various players to reach conclusions about the strengths and weaknesses of networks in the special circumstances of disaster preparation.  相似文献
