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
This article suggests that variations in the dominant pattern of innovation policy coordination can be analysed and understood effectively by dividing innovation and other complementary socio-economic policies into low-complexity and high-complexity tasks.
The effective implementation of these two sets of policy tasks that differ in the extent, nature and intractability of collective action problems confronting the coordination process hinges on the strength of two sociopolitical institutions: bureaucratic organizational structures and interactive governing arrangements. While bureaucratic organizational structures are better suited to delivering low-complexity tasks, interactive governing arrangements are more effective in resolving high-complexity policy problems. They interact differently across political economies to structure the management of coordination challenges and thus give rise to divergent patterns of innovation policy-making. The comparative analysis of innovation policy coordination between Hong Kong and Singapore over the past two decades lends strong support to the central theoretical propositions of the article.
