Forensic Application of Analytical Mechanics in Fatal Fall From a Height

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.     

欠发达地区农民增收难的原因及解决对策——以江西省抚州市为例

欠发达地区农民增收受到多种因素限制,增收渠道少、难以持续、土地经营规模小、农业比较效益差及农业基础设施薄弱等是主要原因。完善政策机制、改善农业生产条件、推进产业化经营及加快小城镇建设等措施,不失为解决当前欠发达地区农民增收难的好对策。     

反恐侦查中的监听权力规制

监听在反恐情报收集中的广泛采用,一方面丰富和发展了侦查机关的侦查手段,有利于打击和惩罚恐怖犯罪;但是另一方面也导致国家刑事侦查权力的膨胀和扩张,从而对普通公民的权利形成更大的威胁。面对这种境况,必然要求在侦查的必要性与保障人权的基本要求之间寻求调谐。     

IDENTIFYING THE PSYCHOLOGICAL FACTORS THAT MEDIATE THE ASSOCIATION BETWEEN PARENTING PRACTICES AND DELINQUENCY*

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.     

SUPRANATIONAL GOVERNANCE OR NATIONAL BUSINESS‐AS‐USUAL? THE NATIONAL ADMINISTRATION OF EU STRUCTURAL FUNDS IN THE NETHERLANDS AND DENMARK

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.

THE EFFECT OF GENDER ON THE DECISION TO INCARCERATE BEFORE AND AFTER THE INTRODUCTION OF SENTENCING GUIDELINES*

The present study explores the relationships between gender and imprisonment decisions in Minnesota before and after the introduction of sentencing guidelines. Results from a series of logistic regression models indicate that gender alone did not have a significant impact on the likelihood of imprisonment, but women with dependent children were significantly less likely to be imprisoned before sentencing guidelines and in the years subsequent to their implementation. The findings suggest that despite the introduction of sentencing reforms, court officials tend to return to issues of substantive justice, and they appear unable to shed their individual or organizational ideas of fairness in sentencing.
