Law enforcement agencies and institutions of higher education have confronted increasing numbers of violent and destructive campus riots and disturbances over the past decade. Problematic is the fact that these riots typically have no underlying cause, other than students’ quest for excitement. Responding to gaps in the empirical literature about these events, this study used data from two waves of surveys to systematically examine those involved in a recurring problem event in a college town that was subject to a police crackdown. The analyses drew on survey responses from over eight hundred event participants in 2002 and 2003, and the results revealed that increased enforcement had a significant effect on crowd composition, including the gender and race of participants, repeat visitors, out-of-town participants, and perceptions about the subjects' overall experience. Implications for law enforcement and community strategies to decrease the size and destructiveness of such problem events are outlined.  相似文献

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

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 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

The European Parliament has generally been deeply distrustful of the comitology system, primarily on the grounds that it allows the national administrations to undermine its supervisory role in the area of implementing legislation. Parliament has therefore sought to use the political, budgetary and jurisdictional means at its disposal to counteract the spread of comitology, or at least to promote the less intrusive forms of committee procedure. These initiatives have not, for the most part, been wholly successful; neither the interinstitutional agreements nor Parliament's arguments before the Court of Justice have produced the results it had hoped for. Parliament has been able, however, to use its Maastricht powers to influence the choice of committee procedure included in legislation adopted under codecision, and its budgetary tactics have forced the Commission to rationalise somewhat the annual expenditure on committees of all kinds and to bring a modicum of transparency into their operation. The imminence of the intergovernmental conference led to a suspension of hostilities towards the end of 1996.  相似文献
