Routine crime in exceptional times: The impact of the 2002 Winter Olympics on citizen demand for police services 总被引:2,自引:0,他引:2
Despite their rich theoretical and practical importance, criminologists have paid scant attention to the patterns of crime and the responses to crime during exceptional events. Throughout the world large-scale political, social, economic, cultural, and sporting events have become commonplace. Natural disasters such as blackouts, hurricanes, tornadoes, and tsunamis present similar opportunities. Such events often tax the capacities of jurisdictions to provide safety and security in response to the exceptional event, as well as to meet the “routine” public safety needs. This article examines “routine” crime as measured by calls for police service, official crime reports, and police arrests in Salt Lake City before, during, and after the 2002 Olympic Games. The analyses suggest that while a rather benign demographic among attendees and the presence of large numbers of social control agents might have been expected to decrease calls for police service for minor crime, it actually increased in Salt Lake during this period. The implications of these findings are considered for theories of routine activities, as well as systems capacity. 相似文献

Both theory and research have been refined to gain a better understanding of when race and ethnicity matter in justice proceedings. In the present research, this line of inquiry was continued by differentiating among minority youth to assess the extent being African American, Native American, and Asian American influenced juvenile justice decision making and how these effects compared to one another and Whites. Utilizing an interpretation of the symbolic threat thesis that emphasizes stereotyping, the authors anticipated Native Americans to be responded to more severely than African Americans, followed by Asian Americans who were anticipated to be responded to more like Whites. The results indicated partial support for these expectations. 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

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

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

Abstract: In the increasingly complex and “horizontal” environment of Canadian governmental decision‐making, the ability of governments to advance a major new policy initiative can be compromised or impeded by the often cumbersome systems evolved to ensure both due diligence and a comprehensive approach. In Ontario, the urgent and multi‐faceted health care reform agenda has been implemented using a new set of policy‐development and program‐implementation techniques. This paper summarizes those reforms. In doing so, it outlines the degree to which the reform agenda has been implemented using techniques and processes that have been grafted onto or even short circuited existing decision‐making systems. The paper also draws conclusions about the potential utility of the Ontario experience both for health care reform and for developing new mechanisms to implement challenging, time‐limited reform agendas within parliamentary systems of government with politically neutral civil services. Sommaire: Dans le contexte de plus en plus complexe et “horizontal” de la prise de décisions gouvernementale au Canada, l'aptitude des gouvernements à promouvoir une nouvelle initiative politique majeure peut être compromise ou entravée par la lourdeur des systèmes élaborés pour assurer une diligence raisonnable et une approche exhaustive. En Ontario, le programme de réforme des soins de santé, urgent et polyvalent, a été mis en œuvre grâce à un nouvel ensemble de techniques d‘élaboration de politiques et de mise en œuvre de programmes. Le présent article résume ces réformes. Ce faisant, il souligne comment le programme de réforme a été mis en œuvre grâce à des techniques et processus qui ont été greffés, ou qui ont même court‐circuité les systèmes de prise de décisions existants. L'article tire aussi des conclusions sur l'utilité possible de l'expérience de l'Ontario en ce qui concerne la réforme des soins de santé mais aussi la mise au point de nouveaux mécanismes pour exécuter des programmes de réforme difficiles, à délai déterminé, au sein de systèmes parlementaires de gouvernement avec des fonctions civiles politiquement neutres. 相似文献

Hair analysis has been presented by some authors as a possible tool of investigation for estimating patients' compliance to long-term therapies. This paper summarises the different publications that have been devoted to this topic and highlights the available statistical data presented to support this proposition. Qualitative results of such determinations may be of some interest but due to the enormous interindividual variations of quantitative data, the idea of using hair analysis to ascertain whether a patient has taken his treatment exactly as prescribed, clearly appears to be inapplicable. 相似文献

A study of the various stressors faced by interns serving as security assistants at the Tenth Pan American Games and the coping mechanisms they utilized was undertaken during the months of July and August 1987. This study revealed that group development can be altered and maladaptive behavior can result among students experiencing high degrees of stress, frustration, and feelings of helplessness, who are subject to a leadership void. The data strongly support the need for planners of similar large-scale internship programs to consider group processes, organizational factors, and interpersonal relations if organizational goals are to be achieved, maladaptive coping mechanisms are to be avoided, and student stress is to be lessened. 相似文献
