This study examines a hot spot policing intervention where private security guards patrolled a specific area in the city centre of a mid-sized Swedish town during summer weekend evenings and nights, aiming to reduce the number of reported street violence incidents. A follow-up of the intervention, using previous years as a control was conducted to measure changes in the number of street violence rates before and during the intervention. The results show non-significant decreases in the number of reported street violence incidents during the intervention. The results can be interpreted in at least two ways: that the intervention had no effects; or that the small, but non-significant decreases observed, are indeed small effects that can be strengthened by modifying the implementation of the intervention. An additional analysis shows that the changes in crime rates are larger at times when the guards adapted a stricter hot spot policing approach, which indicates that with a more structured implementation of the intervention it might be possible to see larger effects.  相似文献

公共政策可行性研究与政策执行力改进   总被引:1,自引:0,他引:1  
公共政策质量与政策执行力密切相关,政策本身的不完善是限制执行力提升的重要因素,而加强政策的可行性研究是提高政策质量的有效途径。政策的可行性研究应该包括政治、法律、组织、经济、技术等内容,当然,不可行性分析也是不可缺少的内容。在实际操作中还应警惕可行性分析的异化与具体政策制定环境的不同影响因素。本文以政策的可行性研究为着眼点,从政策质量提高的角度探讨政策执行力提升的路径。  相似文献

Allele frequencies of 15 AmpFlSTR Identifiler STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA) were analysed in a sample of 100 unrelated autochthonous Macedonian and 102 Macedonian Romani individuals, representing different ethnic groups residing within the same country of Former Yugoslav Republic of Macedonia. The interpopulation comparisons between Macedonians and Macedonian Romani with four south eastern European populations, Kosovo Albanians, Serbians from Vojvodina Province, western Romanians and northern Greeks were performed as well as comparison between Macedonian Romani and Assam population from Asia (India). Reported data point that Macedonian Romani, as an example of an endogamous population of Asian (Indian) origin, show significant allelic differences when compared to neighbouring south eastern European populations.  相似文献

Very little attention has been devoted to the public's opinion of media coverage of court cases despite extensive research on pretrial publicity (PTP). Following a provincial judgment to restrict media access in Quebec courthouses, a preliminary unpublished study found that the public was largely in support of these restrictions. The present study sought to expand on this finding in a more widely generalizable sample. Subjects were recruited from continuing education classes and completed a questionnaire that assessed their support for restricting journalists in courthouses. Nearly 80% of the 243 participants supported media restrictions. Although participants in the four experimental conditions and one of the control groups were largely in favor of the restrictions, one control group was opposed to the restrictions. The results suggest that the public prefers that journalists have restricted access to courtroom participants, resonating research on PTP and the Supreme Court's decision on the case.  相似文献

The evolution of today's information age is mirrored in the growth of the National Library of Medicine's bibliographic services: from the pioneering work of the Library in the last century to develop Index Medicus, to developing the innovative computerized MEDLARS system in the early 1960s, to the easily searchable on-line data bases now available to health professionals. The evolution has not come about without controversy, however, as tension developed between the public sector, where the information was viewed as a social benefit, and the private sector, where it was viewed as a source of profit. The Library has fostered research and development in biomedical communications in the laboratories of its Lister Hill Center and through grants to assist in establishing the field of medical informatics. The future of biomedical communications will be profoundly affected by work now being carried out by the Library: in fields such as biotechnology, through integrative methodologies such as the Unified Medical Language System now under development, and by a grant program to improve the infrastructure for information within academic health science centers.  相似文献

Recent declarations of ‘crises’ in the Mediterranean have been distinctly humanitarian, being linked to human deaths and suffering. The growing emphasis on humanitarianism and human rights has coexisted with a continued security rationale, as the three discourses work together in the governance of EUrope’s borders and in ongoing struggles over movement and control.  相似文献

This analysis examines the complexity of adolescent health risk behaviors using data from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative study of students. The current sample includes 12,955 students (6,626 females and 6,329 males) in grades 9 through 12. Cluster analysis was conducted separately by gender to examine the interrelationships among eight health risk behaviors: sexual activity, general alcohol use, binge drinking, cigarette use, marijuana use, other illicit drug use, fighting, and suicide. Four distinct clusters for females and males were identified based on their profiles of risk-taking behavior. Females and males both report low- and high-risk profiles, and a risk profile with high alcohol use and sexual activity. Females have two distinct risk profiles, one that is highest on every measure of risk compared to others and one that has high levels of fighting and suicide with little participation in substance use or sexual activity. Males have a distinct risk profile with particularly high rates of marijuana use and suicidal behaviors. Few distinctions exist between profiles based on sociodemographic characteristics.  相似文献
