Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios. 相似文献

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems. 相似文献

This paper reflects upon the USA’s war against terror and how it has been reflected in recent attempts to change German law. The author highlights the differences between war and crime, between police law and ius belli and pleads that this differentiation be respected in the formulation of policy. He charts the recent debate about the role of the armed forces in Germany especially in relation to potential missions within the country, particularly in accordance with the aviation protection act, which was found to breach the constitution. The paper highlights the issues as to why this was the case and ends with an account of the anti-terrorist measures undertaken by the EU. 相似文献

The subject of this article is the changing balance between Russia's positive and negative interests in the Conference on/Organisation for Security and Cooperation in Europe (CSCE/OSCE) as these have evolved in relation to Western policies on the OSCE and European security relations in general. Parallel to the decline of positive Russian interests in the CSCE/OSCE, an increase in negative attitudes can be observed, most of which concern the OSCE's activities in post-Soviet countries. While the Soviet Union was traditionally a reliable supporter of the CSCE, the Russian Federation, which initially pursued the same policy, has lost most of its sense of ownership in the OSCE. This change in Russian attitudes is critical for the Organisation's future, for an OSCE without active Russian participation would lose much of its raison d'être. 相似文献

The partnership principle in EU cohesion policy was introduced in order to involve subnational authorities and interest organizations in policy formulation and implementation. In this article we examine how the member states have reacted to this call for a new way of making public policy. We argue that the multi‐level governance literature and the critics of the multi‐level governance framework have not examined implementation structures properly, but have focused on regional influence. We conduct a comparative analysis of the Dutch and Danish implementations of the European Social Fund and the European Regional Development Fund. Our findings show that when examining implementation structures it becomes clear that member states are in full control of the re‐allocation of EU funds. They show that Denmark and The Netherlands have been able to absorb EU cohesion policy within already existing national implementation structures of labour market policies and regional development. One central theoretical implication of our study is that the focus of studies of any fundamental re‐allocation of power resources in cohesion studies should comprise the entire network of implementation rather than the strategies of its individual component actors. 相似文献

In this paper, crucial aspects of technology transfer are considered from the perspective of a small open economy with a predominantly small and medium-sized enterprise structure. The paper uses empirical data from an investigation which prepared the ground for developing a model for the active support of technology transfer in Austria. Experience from technology transfer strategies in other European countries was introduced and integrated in the formulation of policy proposals. These proposals are valid for a broad range of different technologies, while taking into account the possibilities and limitations of technology transfer policy in small open economies. 相似文献
