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

In May 2005, the World Health Organization adopted the new InternationalHealth Regulations (IHR), which constitute one of the most radicaland far-reaching changes to international law on public healthsince the beginning of international health co-operation inthe mid-nineteenth century. This article comprehensively analysesthe new IHR by examining the history of international law oninfectious disease control, the IHR revision process, the substantivechanges contained in the new IHR and concerns regarding thefuture of the new IHR. The article demonstrates why the newIHR constitute a seminal event in the relationship between internationallaw and public health and send messages about how human societiesshould govern their vulnerabilities to serious, acute diseaseevents in the twenty-first century.  相似文献

This article critically appraises the narrative of nationalist resurgence in China in the 1990s that structures much of the secondary literature on Chinese politics since Tiananmen. Adopting a post-structuralist method, Chinese texts from the 1990s are treated as discursive rather than as expressions of a common consensus, emergent ideology or political movement. This makes it possible to bring out the disparate points of view concerning the desirability of nationalism for China and to understand the strategies that are being deployed by authors within the context of everyday Chinese politics. It also reveals the significance of the absence from both the primary and the secondary texts of any mention of the advocacy of nationalism by the political leadership. When this hidden discourse is taken into account, it becomes evident that many of the texts that have been taken as expressions of a nationalist revival are either not particularly interested in nationalism or are highly sceptical concerning its possibilities for solving the problems faced by the Chinese state. Particularly significant is the way in which many of the texts locate themselves in relation to the official discourse on nationalism by appropriating its themes in order to promote and legitimate a wide range of other discourses with which it can be bound up, ranging from democracy to authoritarianism.  相似文献

Jail and prison populations in the United States have continued to grow unabated during the past two decades but crime rates have not declined. Partly in response to the pressures caused by burgeoning correctional populations, the use of alternatives to incarceration has expanded. An ongoing debate centers on the effectiveness of these alternatives. Many criminal justice professionals and some researchers question whether such alternatives seriously restrict the criminal justice system 's ability to incapacitate the active offender. This study deals specifically with two alternatives to incarceration: probation and parole. We examine offender recidivism for a sample of probationers and parolees active in New Orleans, Louisiana, and offer a new approach to addressing the effectiveness issue. Past research has evaluated the effectiveness of alternatives by examining failure rates of diverted offenders. High failure rates, we argue, do not necessarily imply a significant loss of the incapacitative effects of imprisonment. We suggest that a more appropriate measure of the loss of incapacitative effect is the proportion of all offenses committed by persons on probation or parole. Our results suggest that such losses are surprisingly low. The policy implications of our findings are discussed.  相似文献

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.  相似文献
