Some scholars argue that the author of the majority opinion exercises the most influence over the Court's opinion-writing process and so can determine what becomes Court policy, at least within the limits of what some Court majority finds acceptable. Other students of the Court have suggested that the Court's median justice effectively dictates the content of the majority opinion: whatever policy the median justice most wants, she can get. We test these competing models with data on Supreme Court decision making during the Burger Court (1969–86). While we find substantial evidence for both models, the agenda control model gains greater support. This suggests that opinions on the Court on each case are driven, in general, by the interaction of three key variables: the policy preferences of the majority opinion author, the policy preferences of the median justice, and the location of the legal status quo .  相似文献

While much of the implementation literature over the past several decades has recognised the importance of context (e.g. in issues of institutional culture, degree of hierarchy), little of the literature comparing the results of numerous program implementation experiences examines the experience of non‐Western contexts. This study seeks to partially fill this gap by applying the ‘conventional wisdom’ of implementation theory to program implementation experience in Russia. We analyse the implementation of 18 demonstration projects in Russia against 9 success factors identified in the implementation literature. Most of the pilots involved multiple cities; so there are a total of 48 city‐case observations to study. Overall, the findings are that the factors associated with successful program implementation among OECD countries are also those at work in Russia's transitional economy. The weights associated with the various factors may differ, however. One could imagine, for example, that political support counts for more in Russia than in the western local governments. One might also believe that opportunities for learning from other implementers could be more important in the West, where professional associations are more highly developed. The core finding of consistency should be valuable to administrators across transitional economies who can now refer to the rich findings of implementation research with greater confidence of its applicability to their programs. Perhaps equally important is the finding that some of the same factors predominantly associated with successful or troubled implementation in Russia have similar effects in implementation examples drawn from transition and developing nations; there are, however, some important differences.

In 2003 the policy development process in Bosnia and Herzegovina was characterised by international community (IC) dominance. The IC provided the vast majority of the analysis of problems facing the country and drafted many of the laws. This article documents developments from fall 2003 to fall 2006 in the use of evidence and analysis in the policy development process and the role of local policy research organisations (PROs—often called think tanks) in it. The likely relation between these changes and the activities of a PRO mentoring project that operated over the same period is also assessed. Evidence comes as a series of interviews in both years with government officials and members of parliament, on the one hand, and leaders of PROs and advocacy NGOs on the other. The broad picture that emerges from the above review is of a substantial positive development in the policy development process in Bosnia and Herzegovina over the period. Factual evidence and analysis are playing a much greater role, and PROs have been a major provider of this information. The evidence indicates that PROs have been successful in convincing the policy community that they are purveyors of objective, disinterested advice and analysis. The improvements occurred in a conducive environment that steadily placed greater responsibility for policy formation on Bosnian officials. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Using panel data that track individual students from year to year, we examine the effects of charter schools in North Carolina on racial segregation and black‐white test score gaps. We find that North Carolina's system of charter schools has increased the racial isolation of both black and white students, and has widened the achievement gap. Moreover, the relatively large negative effects of charter schools on the achievement of black students is driven by students who transfer into charter schools that are more racially isolated than the schools they have left. Our analysis of charter school choices suggests that asymmetric preferences of black and white charter school students (and their families) for schools of different racial compositions help to explain why there are so few racially balanced charter schools. © 2006 by the Association for Public Policy Analysis and Management.  相似文献

The 1980s have witnessed an intense debate by China’s strategic community over a military strategy in response to what Beijing sees as a shifting, but still complex and potentially troublesome, security environment. though the debate is yet to conclude, the broad contours of the new doctrine have been sketched out. Acknowledging that both superpowers are increasingly constrained by economic, political, and military factors in their contest for supremacy, Chinese analysts continue to warn against lowering armed guard at a time when the focus of the arms race is shifting to new frontiers: outer space and oceans. They would like China to strengthen its national defense rather than rely an arms control to mitigate threats to its security. China is continuing its defense modernization program, which will reshape its force structure and enhance its conventional and nuclear capabilities. and the author ofChinese National Security and Nuclear Arms Control [M. E. Sharpe, forthcoming].  相似文献
