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 analyses how a gendered perspective on community-based tourism (CBT) contributes to the realisation of identity and sovereignty of quilombos. It examines the potential sustainability of CBT coupled with agro-ecological practices within the context of gendered identity politics. Drawing from in-depth ethnographic and archival research conducted between February and July 2015 at Campinho da Independência (Rio de Janeiro, Brazil), the article discusses how female leaders integrate sustainable agro-ecological practices and CBT with environmental education in what they call ‘ethno-ecological tourism’. This approach to CBT strengthens a proudly defiant version of Afro-Brazilian ethnic identity vis-à-vis the state.  相似文献

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency.  相似文献

We all agree on the justification of defending ourselves or others in some situations, but we do not often agree on why. Two main views compete: subjectivism and objectivism. The discussion has mainly been held in normative terms. But every theory must pass a previous test: logical consistency. It has recently been held that, at least in the case of defending others from aggression, objective theories lead, in some situations, to normative contradiction. My aim is to challenge the idea that only objective theories have this uncomfortable feature. In fact, any plausible theory justifying the defense of others, whether subjectively or objectively, can lead to situations of normative inconsistency. Therefore, the logical test is not the most fitting one for choosing between different theories of private defense.  相似文献

The new Spanish Law on Artificial Human Reproduction Techniques is analyzed from the scientific, ethical and legal points of view, paying special attention to the preimplantational diagnosis and the experimental utilization of gametes and preembryos. Other items are also analyzed.  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 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
