Under the sponsorship of the judiciary, the Santa Clara County, California Juvenile Court, in partnership with the Juvenile Mental Health Department and a technical assistance agency (SOLOMON), has pioneered a Juvenile Mental Health Court for seriously mentally ill children who have become involved in the criminal justice system. The judiciary, probation department, district attorney, public defender, county counsel, and service providers have collectively embarked upon the implementation of a modern approach to mental health diagnosis, triage, and treatment services for youth and families who come in contact with the justice system as a result of the combination of serious mental illness and juvenile delinquency. This article presents the court's rationale and protocols.  相似文献

During the 1990s, there has been an enormous increase in influence in criminology of the risk factor prevention paradigm. This aims to identify the key risk factors for offending (in longitudinal studies) and implement prevention methods designed to counteract them (in experiments). In addition, protective factors are identified and enhanced. This paradigm has fostered linkages between explanation and prevention, between fundamental and applied research, and between scholars, practitioners, and policy makers. It has encouraged the globalization of knowledge, cross‐national comparative studies, and the application of similar strategies for research and action in several different countries. The main challenges for the paradigm are to determine which risk factors are causes, to establish what are protective factors, to identify the active ingredients of multiple component interventions, to evaluate the effectiveness of area‐based intervention programs, and to assess the monetary costs and benefits of interventions. The paradigm can be improved using longitudinal and experimental studies, which aim to retain its advantages while overcoming its problems. Ideally, an international network of researchers should collaborate in investigating and explaining results in different countries.  相似文献

In this paper, we develop a latent class modeling method to examine variation in offending trajectories. This model is applied to test the predictions of the trajectory theories developed by Moffitt and Patterson that offending history data can be classified into early onset/life‐course‐persistent offending and late onset/adolescent‐limited offending trajectories, with these trajectory groups being related to different etiological factors. The approach was applied to data gathered over the course of a longitudinal study of more than 900 New Zealand children studied from birth until the age of 18. The analysis identified four trajectory groups, with these trajectory groups corresponding to nonoffenders, moderate risk offenders, adolescent onset offenders, and chronic offenders. The adolescent onset and chronic offender groups were similar to the trajectory groupings predicted by the Moffitt/Patterson theories. Examination of social, family, childhood, and peer factors associated with these offending trajectories suggested the presence of a series of common etiological factors relating to family functioning and early adjustment that discriminated between the trajectory groups. However, evidence of trajectory‐specific etiology also existed, in which the formation of deviant peer affiliations for young people from moderate risk backgrounds led to the rapid onset of offending in adolescence.  相似文献

Scholars of human development argue that a variety of social contexts affect youth development and that the interdependency of these contexts bears on the shape of human lives. However, few studies of contextual effects have attempted to model the effects of school, neighborhood, and family context at the same time, or to explore the relative and interdependent impact of these contexts on youth outcomes. This study provides an examination of the independent and interdependent influences of school, neighborhood, and familial contexts through an analysis of student suspension and juvenile arrest. Findings reveal that school‐based and family‐based informal social controls additively combine to reduce the likelihood of suspension and arrest. Moreover, for suspension, results support the hypothesis that an interdependent compensatory relation is present between the extent of collective efficacy in schools and in the surrounding neighborhood; school collective efficacy has a controlling influence on the likelihood of suspension that becomes even stronger in the absence of neighborhood collective efficacy. However, for arrest, an accentuating effect of school‐based social controls exists rather than a compensatory effect. A lack of neighborhood collective efficacy and a lack of school‐based social controls combine to exert a substantial increase in the likelihood of arrest.  相似文献

Over the past two decades, there has been a growing consensus among researchers that hot spots policing is an effective strategy to prevent crime. Although strong evidence exists that hot spots policing will reduce crime at hot spots without immediate spatial displacement, we know little about its possible jurisdictional or large‐area impacts. We cannot isolate such effects in previous experiments because they (appropriately) compare treatment and control hot spots within large urban communities, thus, confounding estimates of area‐wide impacts. An agent‐based model is used to estimate area‐wide impacts of hot spots policing on street robbery. We test two implementations of hot spots policing (representing different levels of resource allocation) in a simulated borough of a city, and we compare them with two control conditions, one model with constant random patrol and another with no police officers. Our models estimate the short‐ and long‐term impacts on large‐area robbery levels of these different schemes of policing resources. These experiments reveal statistically significant effects for hot spots policing beyond both a random patrol model and a landscape without police. These simulations suggest that wider application of hot spots policing can have significant impacts on overall levels of crime in urban areas.  相似文献

The impact of parenthood on leaving a street gang is not well understood. This is likely because researchers in prior studies have not accounted for multiple dimensions of gang exit, possible gender differences, and potential selection bias. In this study, we use a sample of 466 male and 163 female gang members from the National Longitudinal Study of Youth 1997 to consider the within‐individual relationship between changes in parenthood and changes in claiming gang membership and offending. These data offer the opportunity to consider gender differences and birth parity (i.e., first or second child). The results from a series of fixed‐effects models reveal that motherhood is associated with enduring reductions in both the odds of claiming gang membership and the rate of offending, whereas fatherhood has a temporary beneficial impact on gang membership and offending only for those fathers who reside with their children. In most cases, the beneficial effect of having a child rests in becoming a parent for the first time. On the whole, our study findings demonstrate that parenthood serves as a turning point for a particular group of noteworthy offenders—gang members.  相似文献

Right‐wing populist parties tend to combine criticism of how liberal democracy functions with calls for greater direct democracy. But do their voters share that support for direct democracy? In this article, survey data is used to examine, first, whether right‐wing populist candidates in Australia, Canada and New Zealand were more supportive of direct democracy than candidates of other parties. Second, the views of right‐wing populist voters about the functioning of democracy and direct democracy are investigated. While right‐wing populist candidates turned out to be far more likely to support direct democracy, right‐wing populist supporters did not mirror the candidates. Although these were among the most dissatisfied with how democracy worked, they did not necessarily favour referendums more than other voters. The findings have implications both for how we conceive of the relationship between populism and direct democracy and the remedies proposed for redressing populist discontent.  相似文献

The degree of fiscal decentralization in Spain is similar to main federal countries and greater than unitary ones. The demand of public sector decentralization is based on a supposed efficiency gains that is far from being obvious. Using a data set for the Spanish regions, we reject the null hypothesis of a significant relationship between growth in per capita gross domestic product (GDP) and expenditure distribution among fiscal administrations. Nonetheless, we find empirical support for a relationship between revenue decentralization, far less advanced than the expenditure one, and growth. In both cases we do reject the null hypothesis of a nonlinear linkage between fiscal decentralization and growth in per capita GDP.  相似文献

Over recent years, Europe has experienced a series of Islamic terrorist attacks. In this article, conflicting theoretical expectations are derived on whether such attacks increase populist Euroscepticism in the form of anti-immigration, anti-refugee and anti-European Union sentiment. Empirically, plausible exogenous variation in the exposure to the 2016 Berlin attack is exploited in two nationally representative surveys covering multiple European countries. No evidence is found for a populist response to the terrorist attack in any of the surveyed countries. On the contrary, people in Germany became more positive towards the EU in the wake of the Berlin attack. Moreover, little evidence is found that ideology shaped the response to the attack. The findings suggest that terrorist attacks are not met by an immediate public populist response.  相似文献
