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

Much of what we know about the alignment of voters with parties comes from mass surveys of the electorate in the postwar period or from aggregate electoral data. Using individual elector-level panel data from nineteenth-century United Kingdom poll books, we reassess the development of a party centered electorate. We show that (a) the electorate was party-centered by the time of the extension of the franchise in 1867, (b) a decline in candidate-centered voting is largely attributable to changes in the behavior of the working class, and (c) the enfranchised working class aligned with the Liberal left. This early alignment of the working class with the left cannot entirely be explained by a decrease in vote buying. The evidence suggests instead that the alignment was based on the programmatic appeal of the Liberals. We argue that these facts can plausibly explain the subsequent development of the party system.  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 lungs of 79 children who had died between the ages of 1 week and 2 years old were histologically examined. 59 of these children could be categorized as cases of Sudden Infant Death because of the history and postmortem findings. In the remaining 20 cases a definite cause of death could be established. This is the same collective on which the histological investigations of the lymphatic tissue has been carried out. Morphological changes which are typical for a virus pneumonia were found in a substantially higher frequency in the cases of Sudden Infant Death than in the control cases. The validity of these findings and their possible significance for the cause of death are discussed.  相似文献

Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature.  相似文献
