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

Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines
the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors
and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period
2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability
is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all
models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.

Klagen gegen einen internationalen Sportverband, die auf Feststellung der Unwirksamkeit einer Sperre eines bei einem nationalen
Sportverband besch?ftigten Trainers von Wettbewerben dieses Sportverbandes und auf Unterlassung von Handlungen, die eine Akkreditierung
verhindern bzw erschweren, gerichtet sind, unterliegen der ausschlie?lichen inl?ndischen Gerichtsbarkeit des Sitzstaates;
eine Verbindung solcher Klagen mit einer gegen den nationalen Verband gerichteten gleichartigen Klage ist daher unzul?ssig.
– Eine damit zusammenh?ngende Schadenersatzklage gegen den internationalen Verband steht auch nicht in dem von Art 6 Nr 1
LGVü geforderten Zusammenhang mit einer Klage gegen den nationalen Verband wegen Aufl?sung des Trainervertrages aufgrund der
Sperre. 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

A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is, 20 μl of the solution containing 0.5 μg chlorpromazine/ml. The time needed for the measurement is within 10 min. The chlorpromazine radical thus produced is very stable; for example, 95% of the radical was observed after 24 h. The advantage of this method is discussed by comparing with the ordinary spectrophotometry which requires the purification of the sample. 相似文献
