Ebolaviruses are a diverse group of RNA viruses comprising five different species, four of which cause fatal hemorrhagic fever in humans. Because of their high infectivity and lethality, ebolaviruses are considered major biothreat agents. Although detection assays exist, no forensic assays are currently available. Here, we report the development of forensic assays that differentiate ebolaviruses. We performed phylogenetic analyses and identified canonical SNPs for all species, major clades and isolates. TaqMan‐MGB allelic discrimination assays based on these SNPs were designed, screened against synthetic RNA templates, and validated against ebolavirus genomic RNAs. A total of 45 assays were validated to provide 100% coverage of the species and variants with additional resolution at the isolate level. These assays enabled accurate forensic analysis on 4 “unknown” ebolaviruses. Unknowns were correctly classified to species and variant. A goal of providing resolution below the isolate level was not successful. These high‐resolution forensic assays allow rapid and accurate genotyping of ebolaviruses for forensic investigations. 相似文献

This study documents the results of a controlled experiment designed to quantify the abilities of forensic document examiners (FDEs) and laypersons to detect simulations in handwritten documents. Nineteen professional FDEs and 26 laypersons (typical of a jury pool) were asked to inspect test packages that contained six (6) known handwritten documents written by the same person and two (2) questioned handwritten documents. Each questioned document was either written by the person who wrote the known documents, or written by a different person who tried to simulate the writing of the person who wrote the known document. The error rates of the FDEs were smaller than those of the laypersons when detecting simulations in the questioned documents. Among other findings, the FDEs never labeled a questioned document that was written by the same person who wrote the known documents as “simulation.” There was a significant statistical difference between the responses of the FDEs and layperson for documents without simulations. 相似文献

This article concerns whether and how political candidates adopt social media in their election campaigns. For campaigns, the openness and interactivity of social media tools bring about risks in terms of losing control over the message. Departing from a cost‐benefit perspective, this study addresses the question as to whether certain groups of candidates – differing in incumbency status, party type, gender, generation and urbanization level of the constituency – are more prone to adopt and utilize new social media tools and practices. In order to study how candidates approach social media in an early stage when the benefits are uncertain and the risks are apparent, candidate blogging in the 2007 Finnish national elections is examined. The findings show that the candidates generally were not ready to pursue the full potential of blogs and thereby to accept the risks associated with this open, interactive and personalized way of campaigning. Rather, the candidates took a cautious approach by not engaging extensively in the social media features and practices. However, female candidates and candidates not representing major parties were more likely to utilize a broader range of social media features and practices. The study adds support to the claim that campaigns do not simply adopt and utilize novel social media tools with the purpose of being innovative; they assess risks, costs and benefits. Social media do not alter the basic need of campaigns to control the message and to avoid stress in the campaign organization. 相似文献

The place of corporate ownership and management in local government anti‐poverty strategy in Britain

Since devolution in 1999, the Welsh Government has developed a distinctive approach to the management of local government policy. Alongside an emphasis on welfarism and partnership, local authorities have been exhorted to put the citizen at the centre of public service delivery. Drawing on the notion of assemblage, developed in the governmentality literature, this paper identifies two different rationalities running through Welsh Government policy documents. On the basis of a series of interviews with government officials and their counterparts in the Welsh Local Government Association we find evidence of important tensions in the Welsh approach. While the emphasis on the citizen has worked in building a ‘political rationality’, the evidence from our interviews suggests that it works less well as a ‘government technology’. 相似文献

This article describes and compares two forms of moral regulation employed in connection with insurance institutions. The first governs through moralized personal attributes or pressures like 'temptation' and 'character'. The second governs through moralized institutional or system attributes and processes described in terms of 'efficiency'. The article traces these forms of moral regulation from the mid-nineteenth century to the present, arguing that both continue to inform popular and specialized discourses of risk. 相似文献

Australia supports the control of tuberculosis in Papua New Guinea for reasons of aid effectiveness and a desire to decrease the chance of importing tuberculosis to Australia. This paper analyses the case for this support using both cost‐utility and cost‐benefit analysis. We reach three conclusions. First, Australia directly benefits from its investment in controlling tuberculosis in Papua New Guinea, with a cost of $US 13 million (in 2012 prices) over 10 years earning a net present value of $US 22 million. Second, the longer and more extensive the basic directly observed short course therapy, or basic DOTS, to control tuberculosis, the higher are the returns for Australia. Finally, in addition to surpassing all commonly used benchmarks for being a cost‐effective investment for Australia, a basic DOTS expansion also generates a health benefit for Papua New Guinea that compares well as one of the ‘ten best health buys’ in developing countries. 相似文献
