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 research analyses disciplinary decisions of the New Zealand Lawyers and Conveyancers Disciplinary Tribunal (NZLCDT) from 2011 to 2017 that involve vulnerable clients. Increasingly, scholarship discusses vulnerability as an ethical concept, including in the legal context. Based on published decisions, the present study inquires whether some legal clients’ vulnerability warrants special attention. Twenty-five of the 193 clients in the NZLCDT decisions qualified as vulnerable based upon age, gender, mental health/neuro-disability or immigrant status. The results may inform disciplinary bodies and inspire preventive strategies by lawyers, educators and regulatory bodies. Ultimately, this evidence-based analysis magnifies the importance of client-centred approaches to risk reduction in legal practice. 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

Censorship intensified in Ukraine during Leonid Kuchma's second term as president, and analysts often use this as an indicator of the country's democratic backsliding. This article looks at the motivations behind the media muzzling and questions its effectiveness given that the country exploded in revolution in late 2004. 相似文献

In many states, legal representation for parents of dependent children is inadequate and can be a source of delays in securing permanency for children and unnecessarily protracted court proceedings. Often, such parents also face barriers to accessing services and independent evaluators. These issues are being addressed in the state of Washington through two approaches. The first is a successful enhanced legal representation program that has substantially improved case outcomes. The second is a statewide committee using innovative means to examine systemic responses to the challenges of the Adoption and Safe Families Act. 相似文献

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process. 相似文献

Although there has been speculation regarding the pervasiveness and nature of judicial decisions regarding life-sustaining medical treatment (LSMT), no attempt has been made to empirically assess their prevalence or the issues they address. An exploratory study utilizing a mail survey of a nationwide random sample (N = 905) of state trial court judges was conducted to provide initial information regarding this decision-making process. Twenty-two percent of the responding judges had heard at least one LSMT case, and judicial review did not appear endemic to particular states. The number of judges hearing LSMT cases dropped from 1975 to 1981 but has increased since then. Three major issues predominate: patient competency, appointment of a surrogate decisionmaker, and resolution of the ultimate issue of forgoing LSMT. Relatively few cases either contested a prior directive's validity or involved imposing sanctions for instituting or forgoing LSMT. Although subject to different interpretations, the results suggest the courts are having a significant impact on certain aspects of the LSMT decision-making process. However, the infrequency with which any one judge is called upon to make an LSMT decision causes concern about the judiciary's ability to respond in a timely and appropriate manner. With their potential for a profound effect on the actions of health care providers, greater attention to this decision-making process is warranted. 相似文献
