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

All voting is strategic because the shared outcomes are note within the choice set of any voter, the elements of which can only be strategies. Voting behavior need not re- flect the individual's ordering of outcomes, and the conventional distinction between sincere and sophisticated voting is misguided. In voting choice, the ordinal ranking of outcomes must be supplemented by intrapersonal evaluation of utility differences among these outcomes and also by predictions concerning the behavior of other participants in the nexus of interdependence.  相似文献

In 2006, the Public Choice Society chose a new president using approval voting. There were five candidates, and the election was extremely close. We indicate the sources of support of the different candidates, based in part on spectral analysis, by voters who cast between one and five votes. Using preference information that was also gathered, we show that two candidates different from the approval voting winner, including the apparent Condorcet winner, might have won under different voting systems. Because most voters did not indicate their complete preference rankings, however, these differences are hardly robust, especially since the outcome was essentially a dead heat.  相似文献

Abstract. This article explores the sources of individual-level variation in support economic privatization in seven European post-Soviet countries. It tests economic utilitarian and psychological explanations of variations in support for economic privatization. The economic utilitarian explanation posits that individuals seek to maximize their potential material gains from economic liberalization. The psychological explanation posits that if individuals are generally risk averse, they are not likely to support economic privatization. These hypotheses are then tested using two separate regression models. The first model estimates pooled data from across all seven European post-Soviet economies. The second model is a pooled analysis that interacts country-specific dummy variables with each of the independent variables in order to examine the country-specific effects of the responses. The results show that the economic utilitarian and psychological explanations are both strong predictors of why some support and others oppose privatization in the seven European post-Soviet countries.  相似文献

The dominant paradigm for understanding urban policy change has long been that of “incrementalism.” The incrementalist argument is that institutional fragmentation reduces coordination, and thus discourages what might be called “nonincremental” or “quantum” change. This article seeks to test the incrementalist understanding of urban political change. Is it possible that under certain circumstances fragmentation can encourage quantum change? We will test this possibility with an analysis of homeless policy in New York City. Briefly put, over the last 25 years homeless policy in New York City has developed in a series of quantum jumps with dramatic, short‐term changes in funding, administration, and policy “philosophy.” Policy change followed this trajectory even though New York City's political environment is notoriously fragmented. This pattern contradicts what incrementalism would predict, and therefore suggests that that paradigm must be modified. Urban politics, this study suggests, can sometimes display the nonincremental, entrepreneurial, and “ideational” characteristics that have been identified as typical of the national “new politics of public policy.”  相似文献

Scholars and practitioners within the U.S. education system have focused considerable attention on developing new programs aimed at raising educational achievement for disadvantaged students. New programs are only one way to improve student performance, however; recent work in public administration suggests that public management and implementation practices might also have a large impact on student performance. Existing research shows that managerial networking, managerial quality, and effective personnel management can significantly improve the quality of the education received by disadvantaged students. Additional work highlights the contribution of representative bureaucracy. Because these research agendas have targeted the public administration literature rather than the education policy literature, this article seeks to bring this research back to education policy. Using data from several hundred Texas public school districts, spanning 1995 to 2002, and focusing on disadvantaged student performance (Latinos, blacks, and low‐income students), this article illustrates how both management and processes to enhance the representativeness of teaching faculty produce benefits for disadvantaged students.  相似文献
