In the early to mid-1990s, a group known as Aum Shinrikyo amassed, and used against innocent civilians in Japan, an arsenal of chemical and biological weapons. Two examples are the use of sarin gas in Matsumoto in 1994 and in Tokyo in 1995. The attacks claimed a total of 19 lives and caused thousands of injuries. A review of the scenario, starting in 1994 and early 1995 with the sarin attacks, reveals potential opportunities to preempt such an attack or to mitigate its effects. The Aum Shinrikyo case study is a good learning tool for policymakers and emergency response professionals seeking to form a coherent domestic preparedness strategy. 相似文献

Journalists were alarmed when, in 2005, the United States Court of Appeals for the Eleventh Circuit denied shield-law protection to Don Yaeger, an investigative reporter for Sports Illustrated, in a libel suit by fired football coach Mike Price. Yaeger is a journalist, and Alabama's shield law offers absolute protection even when a journalist is a party to a case. The court's decision turned on the fact that Alabama's seventy-three-year-old statute does not include the word “magazine.” This article shows that this hole in the “covered medium” language of Alabama's statute is not uncommon among the nation's thirty-six shield laws and that the Eleventh Circuit's strict reading of the statute's text is not at odds with current trends in statutory interpretation. Those two facts, combined with the rise of the Internet as an important vehicle for journalism, suggest the time is ripe to scrutinize and modernize shield laws, some of which have been on the books for more than a century. 相似文献

This article proposes a new approach to investigating the substance of lawmaking. Only a very small proportion of bills become law in the U.S. Congress. However, the bills that do become law often serve as vehicles for language originating in other bills. We investigate “text reuse” methods as a means for tracing the progress of policy ideas in legislation. We then show how a focus on policy ideas leads to new insights into the lawmaking process. Although our focus is on relating content found within bills, the same methods can be used to study policy substance across many research domains. 相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献

Eric Hobsbawm's outline of the concept of social banditry suggest certain conditions of existence for that mode of primitive rebellion. Primary among these conditions are the presence of a ‘traditional peasant environment and the absence of ‘industrial capitalism’. This paper presents a critique of Hobsbawm's specifications, and suggest two alternative conditions: the presence of class conflict which unites direct producers, and the absence of effective, institutionalised political organisation of producers’ interests. This reformulation is illustrated by reference to the Kelly Outbreak in late nineteenth century Australia. 相似文献
