Collaboration and Leadership for Effective Emergency Management   总被引:6,自引:4,他引:6  
Collaboration is a necessary foundation for dealing with both natural and technological hazards and disasters and the consequences of terrorism. This analysis describes the structure of the American emergency management system, the charts development of the Federal Emergency Management Agency, and identifies conflicts arising from the creation of the Department of Homeland Security and the attempt to impose a command and control system on a very collaborative organizational culture in a very collaborative sociopolitical and legal context. The importance of collaboration is stressed, and recommendations are offered on how to improve the amount and value of collaborative activities. New leadership strategies are recommended that derive their power from effective strategies and the transformational power of a compelling vision, rather than from hierarchy, rank, or standard operating procedures.  相似文献

This paper examines a number of demographic aspects in congressional districts and states that played important roles in a series of Congressional votes on environmental issues in 2000. These characteristics include urbanization or population density, education, income, race, and employment. Our findings are mixed. While we find some evidence (at least in Senate votes) that population density is a positive predictor of “pro-environment” votes, we also find that things commensurate with the Environmental Kuznets Curve such as income, education, and lifestyle also play an important role in environmental voting.  相似文献

Millions of Ugandan children have become orphaned over the last two decades, the primary cause being the increasing HIV/AIDS epidemic. This phenomenon has prompted the government to institute numerous legal reforms. These internal reforms, implemented in a legal environment based on English common law and increasingly, international standards, greatly influence the legal inheritance rights of Ugandan orphans and their chances for prosperity. In many regions, however, the traditional local mores trump both national and global standards, meaning that while Ugandan parents may own appreciable property upon death, their children rarely receive it, but rather fall victim to “property grabbing” or mismanagement by relatives. The key impediments to solving this problem and to Uganda’s adoption of a more egalitarian system of inheritance include the ineffectiveness of local councils, the inadequate enforcement of the Children Stature, and the heavily centralized and cumbersome structure of the national government. Therefore, significant reforms are needed, including the pronouncement of a national policy regarding orphans, the reduction of national reliance on NGOs, and the restoration of a national legislative effort to codify orphans’ property rights.  相似文献

There is little professional consensusregarding the effect of economic conditionson House Elections. We argue that recentwork still uses the paradigm of Party toorganize their data and tests. Given thatrecent developments in the theory ofcongress emphasize the paradigm ofIncumbency, we investigate the empiricalrelevance of that competing paradigm. Weshow that (1) Incumbency matters in a purePresidential Party Model of HouseElections, (2) Presidential Party mattersin a pure Incumbency Model, (3) Once bothParty and Incumbency are accounted for,economic conditions exert a highlysignificant and temporally stable influenceon House elections, (4) Return Rates aremore affected by economic fluctuations thanare Vote Shares, and (5) Not allPresidential Party incumbents face the samedegree of electoral accountability foreconomic fluctuations.  相似文献
