Research indicates that senators evaluate U.S. Supreme Court nominations on two ideological dimensions: the distance between themselves and the nominee, and the potential effect confirmation would have on the Court median. My analysis of nominations from 1968 to 2006 provides evidence that senators are also influenced by the ideological contrast between the nominee and the departing justice. 相似文献

In Pursuit of the Public Interest 总被引:1,自引:1,他引:0
Carol W. Lewis 《Public administration review》2006,66(5):694-701
What does the injunction “serve the public interest” really mean for public managers, and why is it important? By way of an answer, this analysis systematizes different perspectives on the public interest and offers a multifaceted formulation of the public manager’s duty. It is a process involving the exploration of two concerns—democracy and mutuality—in the current time frame and two others—sustainability and legacy—in the future time frame. 相似文献

Both theory and research have been refined to gain a better understanding of when race and ethnicity matter in justice proceedings. In the present research, this line of inquiry was continued by differentiating among minority youth to assess the extent being African American, Native American, and Asian American influenced juvenile justice decision making and how these effects compared to one another and Whites. Utilizing an interpretation of the symbolic threat thesis that emphasizes stereotyping, the authors anticipated Native Americans to be responded to more severely than African Americans, followed by Asian Americans who were anticipated to be responded to more like Whites. The results indicated partial support for these expectations. 相似文献

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending. 相似文献

The present study drew on four competing theoretical perspectives to examine the relationship between family structure and juvenile delinquency. Using data from the Add Health Study, the authors examined nonserious and serious delinquent behavior across youth from different types of households and also considered how the association between family structure and delinquency might be conditioned by family processes and economic factors. Results from negative binomial regression analyses indicated that, in general, type of household was not a significant predictor of nonserious or serious delinquency. Rather, maternal attachment emerged as the most important determinant of delinquent behavior among youth from all family types. The results are discussed within the context of Hirschi's original interpretation of social control theory and future directions for research are suggested. 相似文献

Abstract: In the increasingly complex and “horizontal” environment of Canadian governmental decision‐making, the ability of governments to advance a major new policy initiative can be compromised or impeded by the often cumbersome systems evolved to ensure both due diligence and a comprehensive approach. In Ontario, the urgent and multi‐faceted health care reform agenda has been implemented using a new set of policy‐development and program‐implementation techniques. This paper summarizes those reforms. In doing so, it outlines the degree to which the reform agenda has been implemented using techniques and processes that have been grafted onto or even short circuited existing decision‐making systems. The paper also draws conclusions about the potential utility of the Ontario experience both for health care reform and for developing new mechanisms to implement challenging, time‐limited reform agendas within parliamentary systems of government with politically neutral civil services. Sommaire: Dans le contexte de plus en plus complexe et “horizontal” de la prise de décisions gouvernementale au Canada, l'aptitude des gouvernements à promouvoir une nouvelle initiative politique majeure peut être compromise ou entravée par la lourdeur des systèmes élaborés pour assurer une diligence raisonnable et une approche exhaustive. En Ontario, le programme de réforme des soins de santé, urgent et polyvalent, a été mis en œuvre grâce à un nouvel ensemble de techniques d‘élaboration de politiques et de mise en œuvre de programmes. Le présent article résume ces réformes. Ce faisant, il souligne comment le programme de réforme a été mis en œuvre grâce à des techniques et processus qui ont été greffés, ou qui ont même court‐circuité les systèmes de prise de décisions existants. L'article tire aussi des conclusions sur l'utilité possible de l'expérience de l'Ontario en ce qui concerne la réforme des soins de santé mais aussi la mise au point de nouveaux mécanismes pour exécuter des programmes de réforme difficiles, à délai déterminé, au sein de systèmes parlementaires de gouvernement avec des fonctions civiles politiquement neutres. 相似文献

Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services. 相似文献

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding. 相似文献
