The horrifying, tragic events of 9/11 made Americans aware of their vulnerability to terrorist attacks and triggered the creation of the Department of Homeland Security along with a substantial increase in federal spending to both thwart terrorist attacks and to increase our ability to respond to such emergencies. Much of this large increase in spending was in the form of direct transfers to states and cities through several grant programs. Homeland Security grants may be used for protection against terrorist activities, thereby enhancing public interests, or as wealth transfers to state and local governments, enhancing the reelection efforts of incumbents, and thus, private interests. Using 2004 per capita Homeland Security grant funding to states and their cities, we find that the funding formula used for some of the grant programs, which allocates almost 40% of the funds in some grant programs through a minimum percent to each state with the rest allocated based on population, means that per capita funding is related to electoral votes per capita, i.e., to the politics of Presidential re-election. However, the funding in other grant programs is also related to some of the dangers and vulnerabilities faced by states and their cities. Some of the variation in per capita grant allocations is also explained by the amount of airport traffic in the state and the state's population density, which are variables closely linked to the state's vulnerability to attack. Per capita Homeland Security grant allocations, however, do not seem to be related to the closeness of the 2000 presidential race.  相似文献

Value Choices and American Public Opinion   总被引:1,自引:0,他引:1  
Individual preferences among core values are widely believed to be an important determinant of political attitudes. However, several theoretical perspectives suggest that people experience difficulties making choices among values. This article uses data from the 1994 Multi-Investigator Study to test for hierarchical structure in citizens' value preferences. The empirical results show that most people make transitive choices among values and that their value preferences have an impact on subsequent issue attitudes. To the extent that citizens exhibit intransitive value choices and/or apparent difficulties in the "translation process" from value preferences to issue attitudes, it is due more to low levels of political sophistication than to the existence of value conflict.  相似文献

Water institutions in India play a crucial role in managing scarce water resources and are central to economic development and poverty alleviation. Designing appropriate institutional mechanisms to allocate scarce water and river flows has been an enormous challenge due to the complex legal, constitutional, and social issues involved. The Indian water sector has been grappling with poor performance and deterioration of public (canal and tank) irrigation systems, high extraction levels of groundwater, and related economic and environmental problems. The objective of this article is to carry out a preliminary assessment of institutional mechanisms available to manage water resources in India. The article surveys various formal and informal institutional arrangements that are used at present and their design features in order to identify those institutions related to superior performance. The analysis indicates that crafting “winning institutions” and the policy frameworks to strengthen them should take into account not only the proven criteria of institutional design but also the changing socioeconomic, political, and cultural factors.  相似文献
