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

AbstractThis article reports and discusses the results of a study that investigated photographic images of children in five online terrorist magazines to understand the roles of children in these groups. The analysis encompasses issues of Inspire, Dabiq, Jihad Recollections (JR), Azan, and Gaidi Mtanni (GM) from 2009 to 2016. The total number of images was ninety-four. A news value framework was applied that systematically investigated what values the images held that resulted in them being “newsworthy” enough to be published. This article discusses the key findings, which were that Dabiq distinguished different roles for boys and girls, portrayed fierce and prestigious boy child perpetrators, and children flourishing under the caliphate; Inspire and Azan focused on portraying children as victims of Western-backed warfare; GM portrayed children supporting the cause peacefully; and JR contained no re-occurring findings. 相似文献

ABSTRACTRecently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics. 相似文献

What drives policymakers to put the interests of others above their own? If human nature is inherently selfish, it makes sense to institutionalize incentives that counter decision makers' temptations to use their positions to benefit themselves over others. A growing literature rooted in evolutionary theories of human behavior, however, suggests that humans, under certain circumstances, have inherent predispositions towards “representational altruism,” i.e., to make an authoritative decision to benefit another at one's own expense. Drawing on Hibbing and Alford's conception of the wary cooperator, a theoretical case is made for such behavioral expectations, which are confirmed in a series of original laboratory experiments. 相似文献
