The study outlined in this article addressed a key limitation of prior research on the punishment of juveniles transferred to adult court by employing propensity score matching techniques to create more comparable samples of juvenile and young adult offenders. Using recent data from the Maryland State Commission on Criminal Sentencing Policy, it tested competing theoretical propositions about the salience of juvenile status in adult court. Findings indicate that even after rigorous statistical matching procedures, juvenile offenders are punished more severely than their young adult counterparts. We found no evidence that this “juvenile penalty” is exacerbated by an offender's race or gender, but it does vary starkly across offense type and mode of transfer, being driven primarily by drug crimes and discretionary waivers. The import of these findings is discussed as they relate to the future of juvenile justice policy regarding the continued use of juvenile transfer to adult court.  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

Hair analysis has been presented by some authors as a possible tool of investigation for estimating patients' compliance to long-term therapies. This paper summarises the different publications that have been devoted to this topic and highlights the available statistical data presented to support this proposition. Qualitative results of such determinations may be of some interest but due to the enormous interindividual variations of quantitative data, the idea of using hair analysis to ascertain whether a patient has taken his treatment exactly as prescribed, clearly appears to be inapplicable.  相似文献

A mock jury study was conducted to test the hypothesis that perceptions of a witness can be biased by presumptuous cross-examination questions. A total of 105 subjects read a rape trial in which the cross-examiner asked a question that implied something negative about the reputation of either the victim or an expert. Within each condition, the question was met with either a denial, an admission, or an objection from the witness's attorney. Results indicated that although ratings of the victim's credibility were not affected by the presumptuous question, the expert's credibility was significantly diminished—even when the question had elicited a denial or a sustained objection. Conceptual and practical implications of these findings are discussed.This research was supported by funds provided to the first author by the Bronfman Science Center.  相似文献

Although studies on drug dealing have examined techniques sellers use to ensure against undercover infiltrations, none has explored the use of such techniques at the interactional level. The objective here is to address this void by exploring the perceptual shorthand dealers use to determine whether buyers in question are undercover. This perceptual shorthand processes one of two types of deception clues in making this judgment: trend discontinuity and interpersonal illegitimacy. Trend discontinuity is associated with police in formants and results from situations in which (I) familiar customers suddenly introduce unfamiliar others who wish to buy drugs and (2) familiar customers suddenly and signifcantly increase quantities they themselves desire to purchase. Interpersonal illegitimacy is associated with undercover agents and results from situations in which unfamiliar buyers emit certain physical and verbal “vibes” believed to be indicative of covert law en forcement personnel. Discussion focuses on the data's presuppositional and microstructural implications for restrictive deterrence (Gibbs, 1975). Data were drawn from semi-structured interviews with 32 semi-institutionalized heroin user-dealers located in a very large western US. city.  相似文献

This paper develops an analytical framework tointegrate static and dynamic effects of theoreticallyrelevant and practically applied investment-decisioncriteria on the marginal rate of substitution betweeninvestment and labour. The new propositions are relatedto the ranking of relative present value, Kalecki'sindex of efficiency and the static version ofrecoupment period criteria. Investors in post-communisteconomies have switched from the recoupment period tothe criteria based on discounting. This is aninstitutional change typical for these economies. Itimplies a choice of techniques with lower investmentintensity, which is best supported by government'spolicy to promote labour mobility.  相似文献
