Fear of gang crime was used as a key justification for harsh punishment policies recently, and gangs were known to be associated with more disorder and crime. There was little systematic evidence about the presence, causes, or consequences of gang-related fear for the public. Prior studies showed that in some people's minds, racial and ethnic diversity was blamed for disorder, community decline, and crime. Using latent variable structural equation models, this article tests this idea and examines the causal relationships among perceived diversity, disorder, decline, and gang fear among Orange County, California residents. Results indicated that for Whites, diversity concerns increased perceptions of disorder, which increased concern about decline and therefore gang fear. For Latinos, concern about diversity increased perceptions of disorder and consequently gang fear, but community concern (decline) was unrelated to gang fear.  相似文献

The sociodemographic factors emphasized in much participation research cannot explain abrupt changes in levels of activity. This study shows how threat of undesirable policy change acts as an impetus to participatory activity, helping to explain temporal variation in participation. Newly available individual-level time-series data are used to show surges in senior citizen letter writing in response to threats to Social Security and Medicare during the 1980s. Policy threat interacts with individual characteristics to produce variations in participatory reaction congruent with the magnitude of the threat to the individual.  相似文献

Child abuse by burning comprises 6–20% of all child abuse cases, but misdiagnosis may arise in cases of some medical conditions. We present two cases of suspected inflicted burns, later diagnosed as staphylococcal scalded skin syndrome (SSSS).  相似文献

This paper discusses the German Greens' recent policy on Israel and Palestine, from the beginning of the first red-green federal government to the present. It looks at Green Foreign Minister Joschka Fischer's diplomatic role in the Middle East, and the Greens' current very "mild" policy with regards to Israel, especially when compared to earlier Green attitudes to the region. This is explained with reference to both the continuing relevance of German history to German foreign policy, and the constraints that participation in the federal coalition — and supplying Germany's Foreign Minister — place on the Greens. The influence of history and power on the German Greens is further illustrated by a comparison of German Green attitudes to Israel with the US Greens' much more critical position.  相似文献

Governments throughout the world are requiring greater use of economic analysis as a way of informing policy decisions. This paper provides a comprehensive analysis of the use of impact assessment in the European Union, using US assessments as a benchmark. We find that recent EU impact assessments include more economic information than they did in the past, although important items are still missing. We also provide evidence that the quality of EU impact assessment increases with the expected cost of a proposal. Furthermore, we find that the quality of EU assessments that report high total costs is similar to that of US assessments.  相似文献

This study investigates the determinants of efficiency in an Italian regional health system and estimates the effect exerted by ownership on hospitals’ performance. To achieve this aim, the Veneto region was considered as a case study and a full dataset (2011–2012) containing nonpublicly available technical data and cost and income items was analyzed. Efficiencies are measured applying a three-stage data envelopment analysis (DEA). Our results suggest that private hospitals perform better than public hospitals in productivity and cost saving, not considering the effect of other environmental and operational variables such as length of stay and beds per capita.  相似文献
