The unusual appearance of crystalline fat structures was observed during the postmortem examination of a motor vehicle accident victim. The crystal structures were characterized using Fourier transform infrared spectroscopy and x-ray diffractometry. The structures were found to be made of triacylglycerols, a dominant lipid structure found in human adipose tissue, capable of forming various polymorphic structures. The morphology of the crystalline material was found using both techniques to be predominantly the beta' form of triacylglycerols. The accelerated growth of such triacylglycerol morphology has been observed as a result of shear stresses in other studies involving edible fats. As a result of the findings of this study, it is proposed that increased shear forces may be responsible for the formation of the unusual fat structure found in the victim. An understanding of the effect of forces on the structure of body fat in high-impact collisions can potentially assist in verifying a high-velocity impact. 相似文献

This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark?) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework. 相似文献

Theoretical and empirical work on collaboration has proliferated in the last decade. The authors’ 2006 article on designing and implementing cross‐sector collaborations was a part of, and helped stimulate, this growth. This article reviews the authors’ and others’ important theoretical frameworks from the last decade, along with key empirical results. Research indicates how complicated and challenging collaboration can be, even though it may be needed now more than ever. The article concludes with a summary of areas in which scholarship offers reasonably settled conclusions and an extensive list of recommendations for future research. The authors favor research that takes a dynamic, multilevel systems view and makes use of both quantitative and qualitative methods, especially using longitudinal comparative case studies. 相似文献

This study examines the use of the Massachusetts Youth Screening Instrument-Second Version (MAYSI-2) for mental health needs among 1643 youngsters in residential welfare/justice institutions in Europe and the USA, identifying gender differences across countries and settings. Overall, the MAYSI-2 appeared to be a reliable instrument among these youngsters, with only some scales falling (slightly) below the threshold of acceptable internal consistency. Girls (vs. boys) in Belgian/USA justice institutions and Swiss mixed welfare/justice institutions displayed higher scores for the angry–irritable, depressed–anxious, somatic complaints, suicide ideation scales. Also, detained girls from Belgium and Switzerland reported higher scores for traumatic experiences. No gender differences were revealed among adolescents in German welfare institutions. Our findings suggest that the MAYSI-2 may serve as a useful mental health screening instrument among youngsters in welfare/justice institutions and that girls in justice institutions and mixed welfare/justice institutions form a particularly vulnerable population with regard to mental health problems. 相似文献

‘Digital restructuring’ denotes a phenomenon integral to but also distinct within economic and political restructuring broadly conceived. The concept of restructuring can be modified with ‘digital’ to forefront the important technological dimension of global restructuring, as well as to indicate developments associated with the new ‘information economy’. Digital technology and digitization have been integral to the scope and speed of the global economic and political restructuring of recent decades. They have constituted the technological conditions for some of the more characteristic aspects of this process; from the flexiblization or outright shedding of labour, to the mobility of production and capital and the globalization of trade and financial markets. This paper seeks to debunk much of the corporate and state mythology of digital restructuring currently in circulation by drawing upon the analyses of digital technology and restructuring advanced by critical scholars and progressive social movements, and to highlight the dangers to progressive political movements and discourses posed by the very nature of these representations. 相似文献

Some regression models are used to test the hypothesis that changes in fertility rates have been caused by changes in socioeconomic conditions. The model is applied to four groups of countries and the conclusion is that no simple relationship exists between fertility changes and environmental changes. This conclusion is at variance with results derived from cross‐section studies and suggests not that there is no relationship between socioeconomic and fertility changes, but only that the relationship may be more complex than that considered in previous models. 相似文献

Between Cold War Imperatives and State-Sponsored Terrorism: The United States and “Operation Condor”
Barbara Zanchetta 《冲突和恐怖主义研究》2016,39(12):1084-1102
Operation Condor was a transnational network of organized state-sponsored terrorism that targeted Communist “subversion.” It was operational in the second half of the 1970s. The key member countries were Chile, Argentina, Uruguay, Bolivia, Paraguay, and Brazil (Peru and Equador joined the network later on, with a more marginal role). Based on declassified documents from the United Nations High Commissioner for Refugees in Geneva and on U.S. documents of various origin, this article will assess the development of the Condor network and the U.S. reaction to such manifest acts of state-sponsored terrorism. 相似文献

A local government practitioner and a marketing academic consider the claims for marketing as a new organising principle for local government. They scrutinise the most frequent objections to the concept of marketing in this context and demonstrate that these have little or no force. This is especially true concerning the emerging paradigms of relationship marketing and Webster's development of the marketing concept. The authors conclude that a marketing philosophy underlies much of the new approach to local government service provision, and set out some of the characteristics which local government marketing needs to have. 相似文献
