Using daily panel data from Detroit, we empirically explore the relationship between the National Football League (NFL) and crime in a city. We exploit the natural experiment of the Detroit Lions’ move from Pontiac, Michigan, to downtown Detroit in 2002. Pontiac is used as the treatment city and non-game day crime, other suburban cities, and other cities outside Detroit MSA are used as the comparison groups. Employing a difference-in-difference approach, we find decreases in assaults and vandalism on home game days in Pontiac relative to the control cities after the Lions’ move. We find weak evidence of a net decrease in larceny and vandalism in Pontiac on home game days following the loss of professional football. No changes in assaults and auto theft are reported. While not conclusive, our results suggest that professional football leads to additional larceny and vandalism incidents but no effects on assaults and auto theft. 相似文献

Systems’ thinking places high value on understanding the context. This study focused on the collection of disaggregated data in order to understand the context, to facilitate improvement of health outcomes. The aim of this article was to assess the implementation of municipal ward-based health data collection (disaggregated data) and health care workers’ perceptions of this data collection process. This cross-sectional study used mixed methods in Amajuba district. The participants were professional nurses at the Primary Health Care level. Of the 131 respondents, 123 (93.9%) collected municipal ward-based health data, and found it useful. Opportunities for improving data collection were identified. Disaggregation of the data at ward level contributes to a better understanding of the target population’s health, assists planning for health needs and enables provision of targeted interventions in order to improve health outcomes, to prevent financial regression and waste of health resources. 相似文献

在网络慈善蓬勃发展的同时,各类失范现象凸显:网络慈善求助信息真假难辨导致诈捐事件频发,善款使用透明度缺失,募捐平台存在谋利行为,网络慈善沦为非法活动的工具。其主要原因包括网络慈善平台信息甄别能力有限、公开透明机制建设不足、网络慈善平台监管不够、配套法律法规不足等。因此,规范网络慈善需要强化网络慈善信息审核、加强公开透明制度建设、强化对网络慈善平台的治理以及推进法治化治理。 相似文献

The Incredible Economics of Geoengineering 总被引:3,自引:1,他引:2
Scott Barrett 《Environmental and Resource Economics》2008,39(1):45-54
The focus of climate policy so far has been on reducing the accumulation of greenhouse gases. That approach, however, requires broad international cooperation and, being expensive, has been hindered by free riding; so far, little action has been taken. An alternative approach is to counteract climate change by reducing the amount of solar radiation that strikes the Earth—“geoengineering.” In contrast to emission reductions, this approach is inexpensive and can be undertaken by a single country, unilaterally. But geoengineering also has worrying consequences: it may harm some countries; it would not address ocean acidification; it would pose new risks. The fundamental challenge posed by this new technology is not free riding but governance: who should decide if and under what circumstances geoengineering should be used? 相似文献

Hybrid organisations present important theoretical and managerial opportunities. We examine a large Finnish multichain retail organisation in order to identify and understand the challenges of hybrids in a retailing context. We are especially interested in how these complex firms try to maintain a balance between the centralised corporate control and the local autonomy and initiative of their retailers. The governance forms and processes identified in the case organisation are discussed with the help of a proposed conceptual framework. We believe that the identified governance problems and practices in the three different retail chains and especially our recommendations will facilitate the understanding of retail hybrid organisations and the management of hybrids in general. 相似文献

论经济法的国家安全职能 总被引:1,自引:0,他引:1
国家经济安全是整个国民经济持续、健康、快速发展的前提,它可以被分为宏观经济安全和发展安全。要使一个国家经济能够安全运转,就需要强有力的保障措施。安全是法律持续性的制度安排,是一切法律的首要价值,所以保障国家经济安全,法律责无旁贷。在众多法律部门中,经济法作为国家干预经济的法律,目的就是克服市场调节的弊端,保障国家的经济安全。 相似文献
