This paper isolates crime prevention policy implications which stem from a series of interrelated environmental studies of residential burglaries. A number of crime prevention strategies are developed using a systems approach. It is argued that changes made to the environments of individuals, groups, communities, organizations, and society can achieve lower risks of residential burglary victimization.  相似文献

Developmentally relevant high-risk dietary situations (e.g., parties where tempting foods are available) may influence overweight youth’s weight control, as they increase risk for overeating. Better self-efficacy for coping with these situations—which preadolescents may learn from their parents—could foster successful weight control. Overweight preadolescents (N = 204) ages 7–12 years (67% female), each with one parent, separately completed the Hypothetical High-Risk Situation Inventory (HHRSI) pre- and post-weight loss treatment. The HHRSI assesses temptation to overeat and confidence in refraining from overeating in response to four high-risk dietary scenarios. Participants generated coping strategies for each scenario. Coping strategies and confidence increased and temptation decreased from pre- to post-weight loss treatment. Parents’ increase in confidence from pre- to post-treatment was associated with preadolescents’ and parents’ weight loss. Tailoring treatments to enhance parents’ coping skills (e.g., building strategies, targeting high temptation/low confidence scenarios) may maximize preadolescents’ weight control.  相似文献

In this article, we argue that when patron‐client relations are grounded in economic relationships, such as between landlord and worker, we should expect clientelism to influence not just how public policy, the state, and the political system work, but also how the economy works. We develop a simple model of the economic consequences of electoral clientelism when voting behavior can be observed. Landlords/patrons provide economic rents to workers, and in exchange workers vote for parties favored by landlords. As votes are used by the landlords to accumulate political rents, vote control increases the demand for labor and for land. The model implies that the introduction of the Australian ballot, which destroys this form of clientelism, should lead to a fall in the price of land in those areas where patron‐client relationships are strongest. We test the predictions of the model by examining in detail the evolution of land prices in Chile around May 31, 1958, for which we collected original data. A characteristic of rural Chile at this time were patron‐client relations based on the inquilinaje system, by which a worker, the inquilino, entered into a long‐term, often hereditary, employment relationship with a landlord and lived on his landlord’s estate. We show that the introduction of the Australian ballot in 1958 led to a fall of about 26% in land prices in the areas where these patron‐client relationships were predominant.  相似文献

US intervention in Somalia (1992) and Iraq (1991) are held as evidence for a more powerful media in the post Cold War era and the thesis that media coverage of suffering people is a major cause of humanitarian intervention. This paper investigates the role of mass media during the 1992 decision to deploy ground troops in Somalia. A media influence model is outlined and then applied to the decision to intervene in Somalia. The research indicates that significant levels of media attention actually followed the intervention decision and that this coverage was framed in a way that built support for the intervention. I conclude there is little evidence to support the claim that media coverage compelled policy makers to intervene or that media coverage was a major factor in policy deliberations. Overall, the role of media in causing intervention in Somalia has been substantially overplayed, instead other factors are likely to have had a far greater effect in causing the intervention. This finding challenges both the thesis that media coverage is a major cause of the deployment of ground troops during humanitarian crisis and suggests caution be exercised with regard to post-Cold War claims of a more powerful and influential media.  相似文献

Abstract

This article offers a method for systematically grading the quality of Islamic State of Iraq and Syria (ISIS) videos based on technical production criteria. Using this method revealed moments when ISIS production capacity was severely debilitated (Fall 2015) and when they began to rebuild (Spring 2016), which the article details. Uses for this method include evaluating propaganda video output across time and across groups, and the ability to assess kinetic actions against propaganda organizations. This capacity will be critical as Islamic State media production teams will be pushed out of its territory as the State collapses.  相似文献
