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

AbstractHistorical materialism envisages law-like tendencies (‘scientific’ Marxism) promoting the development of productive forces and, concurrently, a political praxis (‘active’ Marxism) requiring human intervention. These positions give rise to conflicting interpretations of Marxism: first to understand society, second to change it – to abolish economic exploitation. The twentieth century witnessed a shift in the locus of the contradictions of capitalism to the economically dependent territories of the imperial powers. Socialist parties, when in power and adopting a Leninist political praxis, furthered modernisation and were successful in reducing economic exploitation. The paper addresses the relationship between the scientific and praxis components of Marxism in contemporary global capitalism. It considers post-Marxist interpretations of the changing class structure, the rise of identity politics and the evolving nature of capital. Forms of domination, oppression and discrimination (bureaucracy, patriarchy, racism, militarism and credentialism) give rise to their own distinctive forms of power relations. It is contended that they should not be equated with Marx’s crucial insight into the nature of economic exploitation. Many current Marxist (and ‘post-Marxist’) writers adopt a ‘scientific’ position emphasising the inherent contradictions of capitalism. The author claims that without appropriate political praxis, the resolution of such contradictions is unlikely to transcend capitalism. 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

The management of British diplomacy is being modernised in order to meet the challenges of foreign policy-making in a transformational age. Changing patterns of conflict and cooperation and the progressive erosion of hierarchies and their replacement by networking require that diplomacy as an instrument of foreign policy be better integrated with other government actors in order to sustain its relevance and effectiveness. Focusing on the changed role of planning within the United Kingdom Foreign & Commonwealth Office, this article argues that while these reforms have made some progress towards the integration of diplomats, this process has not gone far enough. It also argues that such integration should not be achieved at the expense of the traditional planning function which contributes a vital source of innovation and analysis in the policy-making process. 相似文献

This article reports on a field experiment on the effect of media information on people’s attitudes towards the justice system.
For the duration of a year a Dutch local newspaper took small groups of readers, called ‘newspaper jurors’, to court sessions
of criminal cases and subsequently reported on their experiences and perceptions. Using a quasi-experimental design, we examined
whether an attitude change in the general reader population of this particular local newspaper occurred as a result of the
jury’s newspaper reports. Findings show that, after the treatment interval of 1 year, no attitude change in the general reader
population could be identified that was absent in the control group. 相似文献

The Rehabilitation Engineering Research Center on Technology Transfer (T2RERC) hosted a “State of the Science” conference in November, 2001. The conference reviewed technology transfer work within the field of assistive technology, and summarized related work in public, private and academic sectors. Invited speakers prepared papers on various topics concerning technology transfer, and related their findings to the field of assistive technology during the ensuing discussion sessions. This paper provides an overview of the material presented by the participants, and explores the implications of their findings for one particular field of application—assistive technology for people with disabilities. 相似文献
