The rare event of a corpse immersed in glacier ice becoming exposed on a glacier surface is closely connected with the glaciological conditions at the scene and the site of the accident. Provided that the time since death is known, certain questions relative to the circumstances of a mountain accident can only be answered by considering glaciological aspects. How the scene of an accident can be reconstructed by inference from the site of discovery is discussed by means of three exemplary cases that occurred on Tyrolean glaciers (Austria) during the past 40 years: (1) Two corpses were discovered close above the equilibrium line in the accumulation area after 25 years. The two victims had fallen down a rock face after the breaking off of a cornice and had come to rest in the uppermost part of the accumulation area. (2) A victim was discovered in the lower ablation area 8 years after falling down a crevasse in the middle part of the ablation area. (3) A female alpinist was discovered at the very end of the glacier after 29 years; it was concluded that the accident must have happened in the accumulation area.  相似文献

Efforts to promote and impose Mandarin Chinese as the language of instruction in ethnic minority schools in the Xinjiang Uyghur Autonomous Region, aimed at further integrating the state and raising regional educational and economic quality, have had mixed success. The 2004 plan to consolidate Han Chinese and minority elementary and middle schools and to make Mandarin the universal language of instruction in those schools is fostering an immersive second-language environment without prior preparation for students, bringing native speakers of Mandarin into unfair competition with non-native speakers. The increased focus on Mandarin has already had grave consequences for ethnic relations, especially in urban Uyghur schools, where the project is focused, while the mandate for change in educational curriculum and methodology has also been poorly planned and remains under-resourced, negatively impacting educational quality. The Chinese government has available to it other language policy solutions that are both more workable and friendlier to minority sensibilities.  相似文献

This article is the result of a master's thesis about children and their universal right to be included in a family environment. This is not only protected under international law, but also intuitive to human beings. HIV‐AIDS continues to threaten lives of children, particularly in sub‐Saharan Africa in the form of orphaning. Looking at a case study from Kenya, it is revealed that, while legal protection is yet to be fully realized in the state, strong cultural norms of value are alive. Currently, the extended family system is the greatest protection to children orphaned or at risk of being orphaned. However, this system was made invisible in the domestic laws of Kenya under the Children Act 2001. This neglect calls for questions not only regarding the protection cultural norms may offer, according to the best interests of children, but also as to the cultural environment being created with the new law.  相似文献

North American research on the policing of ‘domestic violence’ has been very influential among policy makers in Great Britain. In particular, research which purports to verify the deterrence value of arrest has prompted the establishment of over thirty domestic violence units in London and similar initiatives elsewhere in Britain. The paper will outline the nature of the traditional police response to ‘family violence’ in London and the nature of the experimental innovations. Changes in police practice with regard to this type of violence will be put in the context of the organizational constraints and possibilities of policing. Finally, changing police responses to domestic violence will be evaluated in terms of the debate over the possibility of using the state or its organs to achieve social change.  相似文献
