Recent British work has focused attention on preventing repeat victimization as part of an overall crime prevention strategy. Because domestic violence victims are among those most likely to suffer multiple victimizations, they are logical candidates for programs targeted at reducing repeat victimization.
This article reports on a joint law enforcement-social services approach to reduce the incidence of repeat domestic violence. The research design randomly assigned households reporting domestic incidents within two public housing police service areas in New York to receive or not receive a follow-up to the initial patrol response. (The follow-up visit was conducted by a police officer and a social worker.) In addition, housing projects in the same area were randomly assigned to receive or not receive public education about domestic violence.
Neither treatment produced a reduction in violence. However, households in projects that had received public education and households that received the follow-up visits were both more likely to report new violence to the police than households that did not receive the treatments. Moreover, the effect of the follow-up visit was most pronounced among households with more serious histories of violence. The results suggest that the interventions increased citizens' confidence in the ability of the police to handle domestic situations.  相似文献

The purpose of this study was to increase the knowledge base of adolescent substance use by examining the influences of risk and protective factors for specific substance use, namely alcohol, cigarettes, and marijuana. Participants included 271 adolescents and their primary caregivers referred for mental health services across North Carolina. A series of hierarchical multiple regressions showed that the relative influences of risk and protective factors differed depending on the target substance in some cases. History of parental felony predicted use of all 3 substances, although the direction of association was substance specific. Parental behavioral control (how families express and maintain standards of behavior) was predictive only of cigarette and marijuana use, not alcohol use. The different links among risk factors, protective factors, and specific substance use are discussed, and recommendations for both mental health and substance use professionals are offered.She received her M.A. in Psychology from Wake Forest University and is currently a doctoral student in Clinical Psychology at the University of North Carolina at Greensboro.

MOSTof the world's highest mountains are clustered along the barren, jagged area where Tibet, Nepal, and Pakistan meet, but Gongga Shan-in China's western Sichuan province -stands apart. A Western mountaineering team first reached its summit in 1935, and a Chinese team made the climb in the 1950s. The last team to attempt it perished in an avalanche.  相似文献

Abstract

After 9/11 the US Government tried to ‘fix’ intelligence by adopting the Intelligence Reform and Terrorism Prevention Act (IRTPA). Resources increased and, to varying degrees, performance improved – particularly in counterterrorism. This article, however, argues that the constellation of Intelligence Community authorities and organizations, either created or left in place by the IRTPA, coupled with the challenges of a complex security environment, leaves us ill-prepared to deal with the Country’s twenty-first century intelligence requirements. Should that critique prove accurate, and should future intelligence failure(s) be judged strategically and politically unacceptable, the second half of the article provides a framework for revising the IRTPA; the proposals substantially increase the authority of the head of the Intelligence Community, consolidate structures, and create centers of analytic critical mass necessary to meet the knowledge requirements for both regional and transnational security issues. Reflecting the Intelligence Community’s long standing tradition of questioning assumptions, the article is meant to foster reflection and debate about whether the Intelligence Community is postured to meet the needs of the Country, and if not, what needs to change.  相似文献

Similar to other consumer sectors of the global economy, the transfer of advanced conventional weapons and military technologies has entered the globalization process, a process that has qualitatively and quantitatively altered the composition and structure of U.S. national security policymaking. By injecting the decisionmaking process governing arms transfers into the global market place, U.S. policy makers must now reconcile maintaining economic competitiveness within the global system without jeopardizing U.S. national security interests. By subordinating national security interests to global economic imperatives, U.S. decisionmakers are at risk of mortgaging the political, societal, and security welfare of its citizenry for profit.  相似文献

The increased risk of child maltreatment in the presence of domestic violence is well documented, but much remains unknown about factors that modify this relationship. This study investigates the roles of risk and protective factors in the relationship between domestic violence and being reported to the Department of Social Services for child maltreatment. Consistent with the literature, we find a significant overlap between domestic violence and maltreatment. Young maternal age, low education, low income, and lack of involvement in a religious community add to the risk for maltreatment associated with domestic violence. Separation between the maternal caregiver and her partner significantly reduces the risk for maltreatment when domestic violence is reported. A significant reduction in the risk for maltreatment is also found with higher levels of support from the maternal caregiver reported by the child in the context of domestic violence.  相似文献
