The Louisiana statewide assessment of domestic violence attitudes and services was a cooperative effort between the Louisiana Community Policing Institute and the Criminal Justice Program at the University of Louisiana, Monroe. The research project included both surveys and focus groups from Louisiana's eight law enforcement planning districts. Results indicate that the response to domestic violence in Louisiana is generally inadequate. Furthermore, problems exist with respect to the definition of domestic violence among agencies. Finally, four basic barriers to successful intervention were identified, including lack of resources, lack of education and training, victims' lack of confidence in the system, and lack of a coordinated response to the problem. Recommendations are presented for overcoming these obstacles. 相似文献

How partner violence is transferred across generations is relatively unexplored. This paper proposes that anger expression style (constructive, destructive direct, destructive indirect) mediates the relationship between exposure to family violence and dating violence perpetration by adolescents. Data are from 1,965 completed self-administered questionnaires given to eighth- and ninth-grade students in a primarily rural county in North Carolina in 1994. Results varied by gender and type of exposure to family violence. For females, destructive direct and destructive indirect anger expression styles mediated the relationship between experiencing family violence and dating violence perpetration. For males, this relationship was mediated primarily by destructive direct anger expression style. The association between witnessing family violence and dating violence perpetration for females was mediated by destructive direct anger expression style only. Witnessing family violence was not associated with dating violence perpetration for males, and therefore could not be mediated. This study suggests that adolescents exposed to family violence learn anger expression styles that put them at risk of being perpetrators of dating violence. Further research is needed to identify other mediators that explain how partner violence is transferred across generations. 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
