Justice-involved youth have high rates of psychiatric diagnoses, and these youth are often placed out-of-home, although evidence identifies several negative implications of juvenile confinement, especially for youth with psychopathology. Furthermore, youth in the justice system may be processed differently based on gender. As males and females tend to manifest symptoms differently, the psychopathology of youth may act to moderate the relationship between gender and placement in the juvenile justice system. The present study used a large, diverse sample (n?=?9?851, 19.8?% female) to examine whether youth placed in various types of out-of-home facilities differed in terms of externalizing, internalizing, substance use, or comorbid disorders, and to determine the predictive value of mental health diagnoses in placement decisions. The moderation effect of psychopathology and substance use on the relationship between gender and placement also was explored. The results indicated that each type of disorder differed across placements, with internalizing being most prevalent in non-secure, and externalizing, comorbid, and substance use being most prevalent in secure settings. Mental health diagnoses improved the prediction of placement in each out-of-home placement beyond legal and demographic factors such that externalizing and substance use disorders decreased the likelihood of placement in non-secure settings, and internalizing, externalizing, and substance use disorders increased the likelihood of placement in secure and state-secure facilities. The relationship between internalizing pathology and placement in more secure facilities was moderated by externalizing pathology. The relationship between gender and placement was significantly moderated by mental health such that females with mental health diagnoses receive less secure placements. Implications for policymakers and practitioners are discussed, as well as implications for reforming juvenile justice within a developmental approach.  相似文献

Juvenile delinquency has been on the decline for a number of years, yet, juvenile courts continue to assess more than 1 million cases per year. Involvement with the juvenile justice system has been linked to a number of risk factors and consequences that may impact positive youth development; however, evidence-based correctional programs that divert juvenile offenders away from formal processing are limited. Teen Court is a specialized diversion intervention that offers an alternative to traditional court processing for juvenile offenders. Despite the rapid expansion of Teen Courts, there is little comprehensive and systematic evidence available to justify this expansion. This meta-analytic study examines the effects of Teen Court on the recidivism of juvenile offenders. The literature search resulted in the selection of 14 studies, which contributed 18 unique effect sizes with a total sample of 2125 treatment group and 979 comparison group youth. The findings suggest that Teen Court is no more effective at reducing recidivism than (a) formal processing or (b) other diversion programs. Implications of formal and informal court processing for low-risk, first-time young offenders are discussed. The authors draw on the Risk-Need-Responsivity model to provide recommendations for policies and practices.  相似文献

Agentic orientations developed in adolescence have been linked to better health, well-being, and achievements in the years following. This study examines longitudinal parental influences on the development of adolescent children’s agentic orientations, captured by the core constructs of mastery beliefs and generalized life expectations. Drawing on multigenerational panel data from the United States (1991–2011), the study examines contemporaneous family factors, but also how parental biographies (their own transition to adulthood) and parents’ own adolescent agentic orientations influence their adolescent children. Study adolescents were 46% male, 52% white, and 15.6 years old on average. The findings indicate that parents’ early orientations and experiences in the transition to adulthood have little effect on their children’s mastery beliefs, but that parents’ generalized life expectations (in adolescence) and having married before having the child were associated with their children’s more optimistic life expectations. Contemporaneous family income and optimistic expectations among parents-as-adolescents were somewhat substitutable as positive influences on adolescents’ optimistic life expectations. The findings contribute to our understanding of intergenerational and over-time influences on these key adolescent orientations.  相似文献

Over the past two decades, earmarked funding to international development organizations through special-purpose trust funds has increased greatly. This paper studies the incentives for trust funds from the perspective of multilateral agencies, notably the World Bank. A theoretically intriguing type of funds are so-called “pass-on funds,” in which one unit hosts the fund, then passes on its resources to another type of unit for implementation. Each unit has different preferences for the specific types of activities to be supported by the fund. Interviews with World Bank staff and complementary documents demonstrate the rationale for pass-on funds and the associated division of labor between fundraising network units and implementing regional units. While pass-on funds reflect an efficient division of labor between functionally specialized units, they increase the misalignment between sector-specific global priorities and country-specific needs. Organizational reform drove the sudden explosion of pass-on funds around the millennium turn, facilitated by growing availability of donor monies for specific sectors and by lenient internal regulation. Organizational reform undermined budget autonomy of sector units, causing those units to seek new funds in their areas of expertise. A number of reform features also reduced administrative budgets of country units, increasing their demand for pass-on funding grants. The results contribute to the emerging literature on earmarked funding and highlight the need to consider international organizations as heterogeneous actors.  相似文献

Asia is Europe’s largest trading partner and EU-Asia trade relations have undergone a rapid change since the global financial crisis. On a global scale, the new multilateral trade agreements such as the now stalled Trans-Pacific Partnership (TPP) involving European Unions’ (EU) major trading partners such as Japan, Singapore and Vietnam also have the potential to change the trade equations. In this paper, we evaluate the new EU trade policy which has been designed to ensure that the EU benefits from the changing global trade scenario and also look at the steps which have been taken by the EU to promote trade relations with its major trading partners in Asia in the predicted ‘Asian century’. We look into the Free Trade Agreements, which are being negotiated with its Asian partners and seek to understand the reasons which have resulted in delays in their signing and negotiations. We evaluate new policies pushed forward by its Asian partners such as the One Belt One Road policy by China and Japan’s policy of securing a large number of trading agreements in the America. Moving ahead, we also shed light on the indirect factors that may influence the success of EU trade negotiations in Asia such as the EU policy on granting China market economy status and the commencement of the ‘Brexit’ process. Lastly, we try to present a list of immediate priorities for EU in Asia, which will ensure that it secures a toehold in trade with the region. All in all, it is shown that the EU has not one and the same approach for all Asian countries but it negotiates flexibly and individually country by country. Because of this “country by country approach” the EU is also not ready to enter into general EU-ASEAN trade negotiations again.  相似文献
