This article examines whether the career needs of legislators – to be re-elected or to move on to another political post – allow us to explain the rules governing committee structures and the committee assignments individual legislators obtain. It uses the institutional variations provided by Argentina, Costa Rica, and Venezuela to test hypotheses about committee assignments and committee assignment mechanisms. It finds that incentives created by candidate selection procedures and electoral rules show some relationship to committee assignments, but with a good deal of variation across national cases and individual careers.  相似文献

The effectiveness of latent fingerprint development techniques is heavily influenced by the physical and chemical properties of the deposition surface. The use of powder suspensions is increasing for development of prints on a range of surfaces. We demonstrate that carbon powder suspension development on polymers is detrimentally affected by the presence of common white pigment, titanium dioxide. Scanning electron microscopy demonstrates that patches of the compound are clearly associated with increased levels of powder adhesion. Substrates with nonlocalized titanium dioxide content also exhibit increased levels of carbon powder staining on a surface‐wide basis. Secondary ion mass spectrometry and complementary techniques demonstrate the importance of levels of the pigment within the top 30 nm. The association is independent of fingermark deposition and may be related to surface energy variation. The detrimental effect of the pigment is not observed with small‐particle reagent (MoS2 SPR) or cyanoacrylate (superglue) fuming techniques that exploit different development mechanisms.  相似文献

Medieval feoffments to the uses of a last will provided, in effect, a power to devise freehold land, otherwise generally impossible at common law. The Statute of Uses 1536 put an end to this mechanism, and in 1540 the Statute of Wills provided, within limits, a substitute power to devise. But conveyances inter vivos upon trust for the performance of wills continued to be made after 1540; and the distinction in practice between such trusts and wills was less clear than might be supposed: wills under the statutory power were understood as conveyances; executors were frequently trustees in a narrow sense; and the perception that executors were, in a broader sense, trusted, had substantive effects. In understanding wills, trusts and trusting after the Statute of Uses, distinctions between those who are ‘trustees’ and those who are not, or between conveyances upon trust and wills, may be an essential starting-point in bringing order to the sources, but cannot fully reflect the complexity of contemporary arrangements.  相似文献

Europeanisation is now a very prolific area of scholarly research in the social sciences, encompassing among other aspects examination of change in the polities, public policies and animating politics of states arising from engagement with the meta-organisation of the European Union. However, we argue that mainstream social science portrayals of categories of territory, identity and power remain comparatively neglected in existing analyses and the interrelations between these categories is undertheorised, preventing clarification of Europeanisation's underlying processes. We contend that a promising starting-point for resolving these discontents can be found in recent debates in geography focusing upon space and scale.  相似文献

This paper examines the ways in which Palestinian children variously perform and transform the discourse of trauma and the aesthetic of suffering that have come to dominate representations of Palestinian childhood and the Palestinian struggle in general. It is argued that everyday beauty in the lives of Palestinian refugee children, as found in mundane spaces and enacted through interpersonal relationships, constitutes an aesthetic disruption to the dominant representation of trauma as put forward by international humanitarian aid organisations and development agencies. Far from being restricted to the immediacy of everyday spaces and interactions, however, everyday beauty is located within wider national and religious geographical imaginaries, and likewise forms the basis of critiques of social and political injustice, and demands for a more just and equitable future. It is argued that children enact an everyday Islamic ethic of beauty as part of a wider political demand for life itself.  相似文献

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
