This article explores the efforts of diaspora groups to reinvigorate culture. Cultural policy studies tend to focus on efforts of the state to fund and support the maintenance, enhancement, and preservation of national culture(s). This article contributes to this area of research by noting the effects of diaspora groups in achieving many of the same ends as official cultural policy through unofficial means. Using Ukraine as an interpretive case study, the article explores diasporic efforts to respond to a lack of cultural policy at home by invigorating Ukrainian culture abroad. Through the use of social networking tools, Ukrainian diaspora groups in the United States and Canada have been successful in maintaining their culture without the state. This study suggests that cultural policy research should involve not only official state‐centric efforts, but nonofficial diaspora‐centric efforts of cultural invigoration. 相似文献

Judge Learned Hands opinion in United States v. CarrollTowing Co. (1947) is canonized in the law-and-economics literatureas the first use of cost-benefit analysis for determining negligenceand assigning liability. This article revisits the case in whichthe Hand formula was born and examines whether Judge Handsruling in that case would provide correct incentives for efficientlevels of precaution. We argue that the negligence test as usedby Judge Hand is somewhat different from the Hand test as usedby modern law-and-economics theorists. With a game theoreticanalysis of the case, we show that Judge Hands negligencetest could in fact produce games with inefficient equilibria,or with liability determinations opposite Judge Hands. 相似文献

The first half of 1979 saw a continued effort by government to rationalize departmental responsibilities and policies. In the field of human services the government established the Health Commission and the Community Welfare Services Department (discussed in more detail in the two previous Chronicles) and has responded to one of the major contemporary social issues by establishing a Victorian Employment Committee. 相似文献

Ethanol stability in preserved antemortem blood has been widely studied since it is a common practice in cases involving suspected impaired driving to collect antemortem blood in evacuated blood tubes containing sodium fluoride. In some situations, antemortem blood is submitted to a forensic laboratory for ethanol analysis in evacuated blood tubes that contain only an anticoagulant. There has been limited research on ethanol stability in antemortem blood stored without a preservative. On two occasions, antemortem blood was collected from five ethanol-free individuals into 6-ml Vacutainer® tubes containing only 10.8 mg potassium EDTA. The blood tubes were spiked with ethanol to approximately either 0.08 or 0.15 g/dl. Dual-FID headspace gas chromatography was used to analyze 58 blood tubes, 29 from each session, for ethanol 1 day after sample collection and again after 1 year of refrigerated storage (~4°C). Statistically significant decreases in ethanol were detected at the 0.05 level of significance. Mean decreases in ethanol after 1 year of storage for the 0.08 and 0.15 g/dl samples were 0.013 and 0.010 g/dl, respectively. The mean ethanol decrease across all tubes was 0.012 g/dl. The range of decreases for the 58 blood tubes was 0.003–0.018 g/dl. The mean ethanol decreases measured in this unpreserved antemortem blood are comparable in magnitude to those previously observed in antemortem blood containing sodium fluoride after 1 year of refrigerated storage. Ethanol did not increase in the antemortem blood samples despite the absence of sodium fluoride. 相似文献

This article examines the traditional political and economic factors that have been purported to explain the prevalence of insurgency. It tests the following hypotheses at the subnational level in Colombia: guerrilla violence is positively associated with exports; higher levels of insurgency are associated with low levels of GDP per capita or negative growth rates; guerrilla violence emerges in the context of weak state presence; and higher levels of state repression are associated with higher levels of insurgent violence. The analysis utilizes a zero-inflated negative binomial to capture dynamics of both intensity and onset of violence. The econometric analysis is supplemented with cartographic visualization and qualitative analysis. 相似文献
