Although regulation is on the rise in the European Union, the liberalization of the telecommunication and energy markets has not created a uniform European Regulatory model. The principle focus of this article is to examine the interaction and regulatory learning between national regulatory authorities and business in the U.K. and German utility markets to assess the degree of convergence and demonstrate how the regulatory relationship has evolved beyond that envisaged in the initial delegation of powers to the regulator. The article shows that independent regulatory authorities have moved from distant and often confrontational relationships with business to strategic working relationships driven by exchanges of information and reputation building and that regulatory learning and trust have evolved at distinct speeds in sectors and countries depending on the number of regulatory authorities in a market place, the degree to which there are concurrent powers between authorities, their discretion in the consultation process, and the length of time that regulatory authorities had existed. Consequently, significant variance is continuously seen in the business—regulator relationships in comparing the young legalist German regulatory authorities with the established independent and discretion-based regulators in the U.K.  相似文献

The social development model seeks to explain human behavior through specification of predictive and mediating developmental relationships. It incorporates the effects of empirical predictors (“risk factors” and “protective factors”) for antisocial behavior and seeks to synthesize the most strongly supported propositions of control theory, social learning theory, and differential association theory. This article examines the fit of the social development model using constructs measured at ages 10, 13, 14, and 16 to predict violent behavior at age 18. The sample of 808 is from the longitudinal panel of the Seattle Social Development Project, which in 1985 surveyed fifth‐grade students from schools serving high crime neighborhoods in Seattle, Washington. Structural equation modeling techniques were used to examine the fit of the model to the data. The model fit the data (CFI ≥.90, RMSEA ≤.05). We conclude that the social development model adequately predicts violence at age 18 and mediates much of the effect of prior violence. Implications for theory and for prevention are discussed.  相似文献

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
