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

An important component of crime scene reconstruction is bloodstain pattern analysis (BPA). Where BPA concerns impact patterns, estimating the area of origin is critical information for scene reconstruction. Traditionally, this is achieved by measuring individual bloodstains and performing trigonometric calculations; however, 3D scanning has been proposed as a viable alternative for overcoming logistical and practical concerns with the manual method. Therefore, this project aimed to establish whether the FARO Focus 3D scanner and FARO Zone 3D software can improve the accuracy of area of origin estimates relative to the manual method. We created a series of eight bloodstain impact patterns and performed paired analysis using the two methods to estimate areas of origin for each pattern. Our data suggested that FARO-derived estimates were generally more accurate than using the manual method. FARO-estimated heights of origin areas were generally closer to the true distance. Both methods underestimated the distance from the wall for most patterns originating 150mm or greater from the wall, but overestimated distances for patterns originating closer to the wall. The degree to which distances were underestimated increased significantly the further the blood source was from the wall and was greater for FARO-derived estimates. The results of this research contribute to the validation of these instruments for operational implementation for BPA and should be considered alongside the practical benefits of 3D scanning relative to manual methods. Further, 3D scanning can provide reliable BPA reconstruction documentation for technical review and court presentation. 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

Canada's imprisonment rate has not changed appreciably since 1960. This stability contrasts with the increased imprisonment rates experienced by Canada's most obvious comparators—the United States and England and Wales. We examine this divergence and propose several interrelated explanations for Canada's anomalous pattern. While Canada is shown not to be immune to pressure for harsher practices and policies, it has been able to counter or balance these trends with other more moderating forces. In particular, we suggest that Canadians have largely been able to escape several of the wider forces or "risk factors" at the root of higher incarceration in other countries. Further, we suggest that certain protective factors of a historical, cultural, and structural nature can also be identified that have limited the extent to which Canada has adopted the same punitive policies documented in the United States and England and Wales. 相似文献

In recent years, legislators in all fifty states have given grandparents rights to petition for visitation privileges with grandchildren that can be enforced over parental objections. Grandparent visitation rights reflect an effort to protect meaningful relationships children enjoy with nonparental caregivers, enlist the assistance of extended family when the child's nuclear family is disrupted, and defend the interests of grandparents themselves. This psycholegal analysis explores the direct and indirect consequences of grandparent visitation statutes for family functioning. Statutory provisions are summarized, and the effects of these statutes are evaluated in light of what is known about the role of grandparents in child development, how courts evaluate children's "best interests" in grandparent visitation disputes, and how these statutes can alter family functioning in informal ways. The authors conclude that there are risks as well as benefits to children and families in grandparent visitation statutes, and suggest directions for procedural and statutory reform. 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
