The U.S. Supreme Court decisions in Daubert v. Merrell Dow Pharmaceuticals Inc. and Kumho Tire Co. Ltd. v. Carmichael transformed the way scientific expert evidence was reviewed in courts across the United States. To gauge the impact of these rulings on the admission of forensic identification evidence, the authors analyzed 548 judicial opinions from cases where admission of such evidence was challenged. Eighty-one cases (15%) involved exclusion or limitation of identification evidence, with 50 (65.7%) of these failing to meet the "reliability" threshold. This was largely because of a failure to demonstrate a sufficient scientific foundation for either the technique (27 cases) or the expert's conclusions (17 cases). The incidence of exclusion/limitation because of a lack of demonstrable reliability suggests that there is a continuing need for the forensic sciences to pursue research validating their underlying theories and techniques of identification to ensure their continued acceptance by the courts.  相似文献

The current study explores conceptualizations of victimization by men, focusing on threat appraisal, coping appraisal, and beliefs, and seeking to apply protection motivation theory, the applied fear response model, and social cognition. Five hundred and sixty-six male prisoners, comprising adults and adolescents, completed a measure of victimization and perpetration (DIPC-SCALED) and of fear, appraisal, and beliefs (TAB). It was predicted that increased threat appraisal and ineffective coping appraisal would predict increased fear of victimization, particularly among the mutual perpetrator/victim group. This group was expected to select strategies for managing the threat of victimization, which carried more risk to them (e.g., such as an aggressive reaction) and to present with beliefs supporting the use of aggression as a response to victimization. Fear of victimization was predicted by threat and coping appraisal although the deficit for victims appeared in coping appraisal only. Mutual perpetrator/victims presented with a specific difficulty in appraising their ability to cope with threat. Differences in beliefs supporting an aggressive response to threat were also noted across perpetrator and/or victimization groups. The article concludes by outlining the implications for theory and clinical practice.  相似文献

With the increasing use of medical imaging in forensics, as well as the technological advances in rapid prototyping, we suggest combining these techniques to generate displays of forensic findings. We used computed tomography (CT), CT angiography, magnetic resonance imaging (MRI) and surface scanning with photogrammetry in conjunction with segmentation techniques to generate 3D polygon meshes. Based on these data sets, a 3D printer created colored models of the anatomical structures. Using this technique, we could create models of bone fractures, vessels, cardiac infarctions, ruptured organs as well as bitemark wounds. The final models are anatomically accurate, fully colored representations of bones, vessels and soft tissue, and they demonstrate radiologically visible pathologies. The models are more easily understood by laypersons than volume rendering or 2D reconstructions. Therefore, they are suitable for presentations in courtrooms and for educational purposes.  相似文献

This article analyzes the impact of The Community Resources Group Receivership Program undertaken from 1998 to 2002 that provided clean property titles to residents in several informal housing colonias (subdivisions) in South Texas. Survey data were gathered from 260 low‐income households comprising two populations: those who had secure title from the outset, and those who were beneficiaries of the land titling program. Focus group interviews were conducted to explore how the beneficiaries construct the meaning of ownership before and after title “regularization.” Formal titling consolidates understandings of absolute property relations in comparison with de facto rights born of use (legal or not), which strengthens people's sense of self‐esteem and potential for political involvement. We found that, contrary to conventional wisdom, title provision per se appears to have little direct impact either upon home improvement or upon residents' receiving enhanced access to credit and financial services. We also found evidence that informality and illegality is likely to reemerge as owners die intestate, and as they revert to informal land market property transfers.  相似文献

Fetal alcohol spectrum disorder can occur in children when a mother consumes alcohol while pregnant. It can manifest in a range of both physical and mental impairments and in varying degrees of seriousness. The act of consuming alcohol while pregnant arguably constitutes a breach of the duty of care that a mother owes to her unborn child and may lead to an award of damages for children with the disorder. However, to conclude that a duty is owed to an unborn child may be legally problematic. Further, an award of compensation may be of little utility to the child. It is therefore suggested that intervention strategies should instead be implemented which target relevant population groups and which prevent and assist in the management of the disorder.  相似文献

This article explores some of the challenges that transnationalcrimes pose to the operation of transnational justice. By transnationalcrimes, we mean serious violations of international human rightsand humanitarian law that transcend national borders and areperpetrated by state or non-state actors. Many national andinternational legal mechanisms may only address a segment ofthese crimes, creating what we refer to as ‘zones of impunity.’This article examines how these dilemmas are unfolding in threeAfrican contexts: the possibility that Charles Taylor is triedfor crimes in Sierra Leone but not in Liberia; that only Congolese,and not Rwandans or Ugandans, face prosecution for crimes inIturi or elsewhere in the Democratic Republic of Congo; or thatJoseph Kony escapes prosecution in Uganda through being allowedamnesty or exile in Sudan. Our analytic framework considershow geography and politics affect legal responses to transnationalcrimes.  相似文献

This paper challenges the claim of the public administration community that universities are playing an important role in transferring public sector technology to local governments. We provide data from the Lower Mississippi Delta to show that graduate programs in public management and planning are not filling the severe expertise gap facing nonrnetropolitan counties and municipalities. The paper concludes with a series of recommendations on how universities can better fulfill their promise of technology transfer.  相似文献

This article examines a public/private sector initiative instigated by Leeds City Council to redress gender inequality in employment. It uses this independent initiative, Opp2k, to assess the business case for equality of opportunity in a ‘post‐feminist’ context. It considers whether or not intended outcomes will make a coherent attempt to redress structural inequality, or whether this is a response to demographic and economic trends indicating increased demand for female labour, finally it addresses the potential impact of public/private partnerships in implementing equal opportunities.  相似文献
