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

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers. 相似文献

The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal. 相似文献

What drives policymakers to put the interests of others above their own? If human nature is inherently selfish, it makes sense to institutionalize incentives that counter decision makers' temptations to use their positions to benefit themselves over others. A growing literature rooted in evolutionary theories of human behavior, however, suggests that humans, under certain circumstances, have inherent predispositions towards “representational altruism,” i.e., to make an authoritative decision to benefit another at one's own expense. Drawing on Hibbing and Alford's conception of the wary cooperator, a theoretical case is made for such behavioral expectations, which are confirmed in a series of original laboratory experiments. 相似文献

Die von Deutschland nach Art. 59 Abs. 2 GG ratifizierten europ?ischen und internationalen übereinkommen zum Denkmal- und Kulturgüterschutz
müssen in nationales Recht transformiert werden. W?hrend die L?nder im Rahmen ihrer Kompetenz (Art. 30, 70, 83 GG) Denkmalschutzgesetze
erlassen haben, hat der Bund in einschl?gigen Gesetzen wie dem Bundeswaldgesetz den Denkmalschutz bisher nicht berücksichtigt.
Dabei ist bei einem Waldanteil von 30% der Wald mit seinen historischen Kulturlandschaften und seinem Waldboden als Archiv
der Natur- und Kulturgeschichte von besonderer Bedeutung. Da Deutschland 60 Jahre nach Kriegsende endlich auch ausdrücklich
ein Kulturstaat werden soll, ist es an der Zeit, dass die Belange des Denkmalschutzes auch im Bundeswaldgesetz (z.B. §§ 1,
2, 9 oder 11 BWaldG) berücksichtigt werden. Einige Verpflichtungen zum Denkmal- und Kulturgüterschutz sind heute ohnehin bereits
V?lkergewohnheitsrecht (Art. 25 GG). 相似文献

The EU has regulated chemicals since the late 1960s using both general and sectoral legislation, and exposure-based, hazard-based and risk-based decisions. A new proposal from the European Commission – on the Registration, Evaluation and Authorization of Chemicals (REACH) – will build on the experiences of the existing legislation and introduce some new concepts in the management of chemicals. This article is aimed at assessing the current chemical control mechanisms in the EU and those put forward in REACH to demonstrate how REACH is a new paradigm in chemicals management. REACH will carry forward today's experience and approach to the management of chemicals in the EU and introduces some novel aspects, such as utilizing market-based mechanisms and putting into operation the 'substitution principle'. 相似文献
