The floods of 2007, experienced across much of England, resulted in local authority organisations, including Fire and Rescue Services, mounting large-scale responses and incurring additional and unexpected expenditure. Although central government activated funding schemes, some local authorities fell below the thresholds set and had to absorb the additional costs. This raised a question of what alternative methods were available to allow these local authority organisations to finance such unexpected costs. Weather derivatives are widely used in certain sectors to manage the financial risk that arises from undesirable weather conditions and the objective of this research is to explore the reactions of an FRS towards the use of these financial instruments in managing additional costs, such as those arising from the 2007 floods. Our findings suggest that a combination of risk-aversion, lack of specific financial knowledge and comfort with the status quo seem set to stifle development of weather derivatives as an innovation in public sector risk financing. However, this exploratory study suggests that the method has some merit and is at least worthy of further examination.  相似文献

The proportion of votes cast before election day has risen steadily over the last two decades. Previous research asked how early voting has impacted voter participation. In this article, we ask how early voting has affected the flow of information to voters through the mass media. By increasing the number of days voters are able to vote, are we also increasing the number of days that candidates and campaigns continuously disseminate campaign-related information to the news media? Is news coverage of campaigns quantitatively and qualitatively different when opportunities to vote early are available and utilized? Our expectation is that early voting significantly influences the volume and nature of campaign news coverage. We study the effects of early voting on campaign news coverage of gubernatorial and Senate races in 2006 and 2008. Our findings reveal that the volume and content of campaign news coverage is significantly influenced by early voting.

In literature, cases of nutmeg abuse have been described repeatedly, but only one fatal case of poisoning was reported [1]. In the present case, myristicin (4 microg/ml) was detected for the first time in the postmortal serum of a 55-year-old woman. Identification was achieved with the aid of UV-VIS spectroscopy and TLC; for quantification, HPLC was used. Because also flunitrazepam (0.072 microg/ml) was found, death had probably been due to the combined toxic effect of both substances. From 1996 to 1998, in a series of cases, seven poisonings with nutmeg were recorded by the Erfurt Poison Information Centre. Even where higher doses (20-80 g of powder) had been ingested, a life-threatening situation was never observed. In one of these cases, a myristicin blood level of 2 microg/ml was measured 8h after ingestion of two to three tablespoonful of nutmeg powder (approx. 14-21 g, or 280-420 mg/kg).  相似文献

This article disputes the premise dominant in moral philosophy and the social sciences that a strict definition of terrorism is needed in order to evaluate and confront contemporary political violence. It argues that a definition of terrorism is not only unhelpful, but also impossible if the historicity and flexibility of the concept are to be taken seriously. Failure to account for terrorism as a historical phenomenon produces serious analytical and epistemological problems that result in an anachronistic, ahistorical, and reductive understanding. Because there are no historically or contextually stable answers to the question what terrorism is, this article argues for a novel account of terrorism that replaces the attempt to define terrorism with an analysis of its meaning and function within a specific context.  相似文献

福利社会与发展中的斯堪的纳维亚福利国家   总被引:1,自引:0,他引:1  
欧洲各国致力于福利国家的建设已逾百年,经历了两次世界大战.各国在社会投入水平和福利机构方面的巨大差异至今仍在,但是各国对于福利社会的可持续性的认可和公众对福利社会的高度承诺则是基本一致的.各福利社会有来自各方面的维系:中央政府或地方政府、公司企业、家庭和自发组织的机构.不同的福利社会体系与它们之间的关系长期以来对欧洲各福利国家有着不同的意义,形成了具有不同特点的福利制度.在20世纪最后十年里重建福利国家的痛苦过程中,经济增长和社会发展之间的关系一直是整个斯堪的纳维亚地区社会问题的争论热点.然而到目前为止,效率与平等之间的冲突大多得到了解决,在北欧五国都保持了福利政策的稳定.该地区独特的历史经验并不排斥发展中国家的政府和机构为了发展福利事业而积极推行普及政策所做出的努力.  相似文献
