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

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers.  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

Corporate social responsibility (CSR) is increasingly being promoted as an instrument for global governance to address the regulatory vacuum surrounding transnational business activities and as a method for encouraging business to contribute to sustainable development at the national level. Originally a business-driven, American concept, CSR has now been adopted and promoted by a wide range of governments and multilateral institutions. However, the socio-political model underlying CSR is far from neutral and may conflict with existing models in the societies in which it is introduced. In this article a typology of possible governmental interpretations of CSR is developed, and how CSR is transformed and adapted in its meeting with Nordic governments in order to fit the “Nordic Model” of state-market-society relations is analyzed. The analysis suggests that pre-existing political-economic institutions and cultural norms deeply affect the interpretation of CSR, and that this, when combined with ongoing national political processes, leads to a highly transformed concept of CSR.  相似文献
