Electoral surveys conducted as part of the regular series of British Election Studies have used a stratified, clustered sampling design. This is constructed to ensure a nationally representative sample of voters (after weighting) but does not necessarily ensure a representative sample of the different social areas within the country. Much recent work has indicated the important role of local social and electoral milieux in the structuring of electoral behaviour but these are not reflected in the sampling design. An analysis of the geography of the face-to-face pre-election component of the 2005 BES shows not only that it was unrepresentative of certain types of area (defined using bespoke neighbourhood data) but also that it was less representative of such areas than the two (larger) internet samples (pre- and post-election) also undertaken as part of the 2005 BES. This suggests the need to reconsider the nature of the sample designs (even the entire survey methodology) to be deployed at future election studies in Great Britain. 相似文献

This article examines the cross-sectional association between acculturation, acculturation stress, drinking, and intimate partner violence (IPV) among Hispanic couples in the U.S. The data being analyzed come from a multicluster random household sample of couples interviewed as part of the second wave of a 5-year national longitudinal study. The overall survey response rate for the second wave is 72%. Participants are Hispanic couples 18 years of age or older (N = 387). Results show that, among men, lower acculturation is positively associated with higher acculturation stress, which is directly related to a greater likelihood of involvement in IPV. These associations are also present among women. However, data for women show an additional path linking higher levels of acculturation directly to IPV. Drinking is not associated with IPV, independent of gender. Acculturation, directly or through acculturation stress, increases the likelihood of IPV. 相似文献

Evaluation of Commercial‐off‐the‐Shelf Materials for the Preservation of Bacillus anthracis Vegetative Cells for Forensic Analysis, 下载免费PDF全文
Daniel J. Angelini Ph.D. Jacquelyn V. Harris B.S. Laura L. Burton B.S. Pooja R. Rastogi B.S. Lisa S. Smith M.S. Vipin K. Rastogi Ph.D. 《Journal of forensic sciences》2018,63(2):412-419
Environmental surface sampling is crucial in determining the zones of contamination and overall threat assessment. Viability retention of sampled material is central to such assessments. A systematic study was completed to determine viability of vegetative cells under nonpermissive storage conditions. Despite major gains in nucleic acid sequencing technologies, initial positive identification of threats must be made through direct culture of the sampled material using classical microbiological methods. Solutions have been developed to preserve the viability of pathogens contained within clinical samples, but many have not been examined for their ability to preserve biological agents. The purpose of this study was to systematically examine existing preservation materials that can retain the viability of Bacillus anthracis vegetative cells stored under nonpermissive temperatures. The results show effectiveness of five of seventeen solutions, which are capable of retaining viability of a sporulation deficient strain of B. anthracis Sterne when stored under nonrefrigerated conditions. 相似文献

Injuries of the Head from Backface Deformation of Ballistic Protective Helmets Under Ballistic Impact 下载免费PDF全文

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed “behind armor blunt trauma” (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400–460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear. 相似文献

The British Indian Ocean Territory (BIOT) is one of Britain's most controversial Overseas Territories. Its indigenous people, the Chagossians, were exiled from their homes in the 1960s and 1970s so that BIOT could play host to a US military base on the island of Diego Garcia. Meanwhile, Diego Garcia has been tarnished by revelations regarding its role in the CIA's ‘extraordinary rendition’ programme and by allegations of torture. And earlier this year, an international tribunal ruled that the UK government had violated international law by pushing through a Marine Protected Area to cover the territory over and above the protestations of neighbouring states. In this article, I argue that allowing the resettlement of BIOT by the Chagossians would go a long way towards improving the way that the territory has been governed for the past five decades. 相似文献

Various forms of ‘boundary‐crossing’ practices continue to proliferate in public management and public service provision (i.e. activities that require engagement and collaboration across sectors, institutions, and organisations). Yet the dynamic nature of this type of joined‐up working is proving to be a major management challenge. In this paper, we bring a number of concepts to bear on the management of joined‐up and cross‐boundary working in public management of complex social issues. Firstly, we present the concept of ‘adaptive management’, which we draw from field of environmental policy and planning (and human ecology). Secondly, we introduce a rethinking of the role of ‘policy targets’ using a complexity lens. These concepts are integrated into a practice heuristic (or framework) designed to assist cross‐boundary policy implementation in real‐world settings. We argue that adaptive management approaches may have significant utility for ensuring effective governance in uncertain environments. 相似文献

Pigeons and people: mortal enemies or lifelong companions? A case study on staff perceptions of the pigeons on the University of South Africa,Muckleneuk campus 下载免费PDF全文
Pigeons have been a part of our lives for as long as we can remember. Some people view them with joy, others disdain. Regardless of the perception, control measures are often implemented against the birds in a bid to reduce their presence in urban environments without considering the views of members of the public in the process. Complaints about pigeon activity are, typically, given more attention than praise for these birds. However, people who are pro‐pigeons are often not provided with the forum to express their views of the birds. This study explored the perceptions of staff with regard to the pigeons inhabiting the University of South Africa's Muckleneuk campus. Two hundred and forty‐six participants provided their opinions on the pigeons, their related activities and the perceived impact on staff on the campus. Recognising that both people and urban wildlife play a role of cause‐and‐effect in human–wildlife conflicts can contribute to understanding peoples' relationships and perceptions of animals which transgress the boundaries between urbanisation and nature. By considering peoples' perceptions, attitudes and behaviours towards urban wildlife, management strategies can be significantly informed in the process of mitigating conflict. The study has shown that the negative perception of pigeons, which was assumed to be the position of all the people affected by the pigeons at the University of South Arica's Muckleneuk campus, is in fact incorrect. Participants would rather encourage the nesting and breeding activities of the pigeons on campus, as they felt that the human–pigeon interactions and the viewing of squabs in nests contributed positively to their work environment. Pigeon control strategies should therefore not solely be on the biological aspect of a perceived pigeon problem, but should also include the human association.
