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

Newspaper juries     
This article reports on a field experiment on the effect of media information on people’s attitudes towards the justice system. For the duration of a year a Dutch local newspaper took small groups of readers, called ‘newspaper jurors’, to court sessions of criminal cases and subsequently reported on their experiences and perceptions. Using a quasi-experimental design, we examined whether an attitude change in the general reader population of this particular local newspaper occurred as a result of the jury’s newspaper reports. Findings show that, after the treatment interval of 1 year, no attitude change in the general reader population could be identified that was absent in the control group.  相似文献

This article contributes to the development of theories on European integration by testing and exploring statistical models on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003. We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic models might be an interesting avenue for future conceptualizations of the EU integration process. This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to thank the seminar participants for useful comments.  相似文献

COMPSTAT, the latest innovation in American policing, has been widely heralded as a management and technological system whose elements work together to transform police organizations radically. Skeptical observers suggest that COMPSTAT merely reinforces existing structures and practices. However, in trying to assess how much COMPSTAT has altered police organizations, research has failed to provide a broader theoretical basis for explaining how COMPSTAT operates and for understanding the implications of this reform. This article compares two different perspectives on organizations—technical/rational and institutional—to COMPSTAT's adoption and operation in three municipal police departments. Based on fieldwork, our analysis suggests that relative to technical considerations for changing each organization to improve its effectiveness, all three sites adopted COMPSTAT in response to strong institutional pressures to appear progressive and successful. Furthermore, institutional theory better explained the nature of the changes we observed under COMPSTAT than the technical/rational model. The greatest collective emphasis was on those COMPSTAT elements that were most likely to confer legitimacy, and on implementing them in ways that would minimize disruption to existing organizational routines. COMPSTAT was less successful when trying to provide a basis for rigorously assessing organizational performance, and when trying to change those structures and routines widely accepted as being "appropriate." We posit that it will take profound changes in the technical and institutional environments of American police agencies for police departments to restructure in the ways anticipated by a technically efficient COMPSTAT.  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
