We report a case of homicide by hanging of a 29-year-old woman that was committed by her husband, who nearly escaped from justice. We offer some reflections on the rarity of this method of mechanical asphyxia in cases of homicide, and on the difficulties in the diagnosis of the medico-legal etiology of these situations. We also offer a short review of similar cases in the medico-legal literature.  相似文献

In order to compare the dermal changes after exposure to direct current (d.c.) with changes after influence of acid and base influence, the skin of fully anaesthetized Danish Landrace pigs were exposed to acid and basic solutions. Biopsies were obtained immediately after and up to day 7 after the injury. Collagen fibres with increased affinity for eosin and irregular cross-striation in polarized light together with shrunken cells with dark stained nuclei were found just beneath the epidermis immediately after application of 1 N HCl. Immediately after exposure to 1 N NaOH dispersed collagen fibres showed increased eosinophilia and a fine densely spaced cross-striation in polarized light and vesicular nuclei were present within dermal cells. During the following days a narrow demarcation zone of neutrophilic granulocytes separated the zone containing abnormal collagen fibres from normal tissue below. Calcified collagen fibres were not observed and no other abnormal histochemical reactions were present. It is concluded that the morphology of acid induced lesions and base induced lesions shows resemblance to the morphology of anode and cathode lesions, respectively, but not to heat lesions. The reason for not finding depositions of calcium salts on collagen fibres in skin exposed to basic solutions could be a non-optimal pH in the tissue or that other electrochemical processes than shift in pH are necessary for the calcification process.  相似文献

The course of alcoholism. Long-term prognosis in different types   总被引:3,自引:0,他引:3  
The disease concept of alcoholism was first introduced into the medical literature by Magnus Huss in 1984. Since that time many authors have attempted to define therapy-related sub-groups of chronic alcoholics but have been unsuccessful until now because alcoholism represents a complex development and becomes apparent in various clinical pictures. As the method of cross-sectional investigations does not seem to be able to produce reliable results, we performed a prospective long-term study of 444 alcoholics. The methodological claims in literature were taken into consideration like selection criteria, programmes and goals of therapy, follow-up rate and time, etc. Careful observation of the pertinent parts of the pathogenetic pathway leading to chronic alcoholism enabled the authors to establish 4 sub-groups of alcoholics relevant for treatment.  相似文献

Has the emergence of international jihadist terrorism led to common threat perceptions and responses in Europe? The article argues that the homogenization thesis is based around a misguided functionalist notion of a single ‘optimal response’ to an alleged new and potentially catastrophic kind of threat with uniform consequences for all ‘Western’ countries. Drawing on insights from different bodies of literature, the article elaborates a theoretical framework to understand variations in threat perceptions vis-à-vis international terrorism and enrich the socio-linguistic securitization approach of Barry Buzan, Ole Wæver and Jaap de Wilde (Security: a new framework for analysis, London: Lynne Reinner, 1998). The article then empirically examines the rise and fall of threat perceptions among selected European publics between 2000 and 2008. Threat perceptions did converge in the aftermath of the 9/11 attacks, but soon afterward started diverging. The article considers the reasons for this finding as well as the implication for the evolution of counter-terrorist policies in the European Union.  相似文献

ABSTRACT

Our longitudinal study examined the effectiveness of BSW IVE Scholar training (n = 52) compared with a matched cohort (n = 57) of traditionally trained employees. The BSW IV-E Scholars felt significantly more prepared than their traditionally-trained coworkers. BSW IV-E Scholars were significantly more likely to be retained in the first five years of employment than the matched cohort trainees. The study lends strong support for the retention and preparation advantages of BSW Title IV-E training over traditional employee training. This is important given the significant investment of training dollars for IV-E at the Federal, state, and local levels.  相似文献

ABSTRACT

This article examines the content of North Korea's juche ideology by analyzing official texts in comparison with Confucian classics and new religious movements in South Korea. The comparison revealed a series of similarities that vividly demonstrate that juche ideas have absorbed core elements of Korean and East Asian philosophical traditions.  相似文献

ABSTRACT

Between 2014 to 2016 we conducted mixed-methods research exploring girls’ experiences of growing up in the UK in the 21st century. We spoke to girls and young women between the ages of 10 and 24 in England, Wales, Scotland and Northern Ireland to gain a qualitative snapshot of what matters to girls. We also conducted the first quantitative study of a range of quality of life indicators disaggregated by age and gender in the UK to garner a statistical view of geographically-based experiences of growing up girl. The study was commissioned by Plan International UK and The State of Girls’ Rights report was launched in September 2016. What struck us at the time of writing the report was the resonance between challenges girls raised in 2016 and those proclaimed by Wollstonecraft in her 1792 treatise, A Vindication of the Rights of Woman published over 200 years earlier. Here we bring together these voices from the 18th and 21st centuries to consider the continuing legacy and resonance of Wollstonecraft’s ideas in thinking about growing up girl in Britain.  相似文献
