In cases where human remains are unidentified because there is no initial identification hypothesis, limited contextual information, and/or poor preservation, radiocarbon (14C) dating may be a useful tool to further assist with identification. Through measuring the amount of 14C remaining in organic material, such as bone, teeth, nail, or hair, radiocarbon dating may provide an estimated year of birth and year of death for a deceased person. This information, may assist in, establishing whether a case of unidentified human remains (UHR) is actually of medicolegal significance and therefore, requires forensic investigation and identification. This case series highlights the application of 14C dating to seven of the 132 UHR cases in Victoria, Australia. Cortical bone was sampled from each case and the level of 14C was measured to provide an estimated year of death. Four of the seven cases analyzed contained the levels of 14C consistent with an archeological timeframe, one contained a level of 14C consistent with a modern (i.e., of medicolegal significance) timeframe, and the results for the remaining two samples were inconclusive. Applying this technique not only reduced the number of UHR cases in Victoria but also has investigative, cultural, and practical implications for medicolegal casework in general. 相似文献

Most biometric age estimation methods used in anthropological and forensic science for juveniles are based on unidimensional measurements (length or width). Here, a new method using bidimensional data was tested. A 3D morphometric analysis was performed on 108 CT scans of ilium bone of juveniles (from 20 gestational weeks to 12 years old). The sample was divided into training and validation groups. Best predictors were determined by comparing the efficiency of each variable (length, width, area, and module: a product of length and width). We established linear and polynomial regressions for each parameter for both sides. Applying the equations to the validation sample showed no significant difference between real and predicted ages. For age estimation, the area and module parameters yielded better results than unidimensional measurements. The results from this preliminary study were highly conclusive, and it would be interesting to extend the work, covering larger samples, and other bones. 相似文献

If electoral abstention is linked to party preferences, low turnout—as witnessed in European Parliament elections—may hurt some parties and benefit others. In order to assess this possibility, we compare, in the member states of the EU, parties’ vote shares in the 2009 European Parliament elections with the results that would have been obtained had turnout reached the level of national general elections. We find that the effects of low turnout are minimal, and that—except for a single seat—higher turnout would not have resulted in a different composition of the European Parliament. 相似文献

Abstract The purpose of the present work was to investigate the effect two eyewitness factors, accent and ethnic background, have on the perceived favorability of eyewitness testimony and case disposition in criminal trials. Six variations of testimony were created and videotaped. The videotapes varied by accent and ethnic background of the eyewitness; the testimony text was identical. Four eyewitness favorability variables, (a) credibility, (b) judgment of accuracy, (c) deceptiveness, and (d) prestige, as well as their relationship to case disposition, were measured. One hundred and seventy-four undergraduate participants viewed one of the six videotapes. Results indicate that there was a significant main effect of accent for the four eyewitness favorability variables. Accent by ethnic background interactions also yielded significant findings for the four variables as well as for the defendant's degree of guilt. Results were interpreted using the Elaboration Likelihood Model. The potential importance of these results for judicial settings is discussed. 相似文献

地区间主义是国际关系的新实践,同时也正在成为国际关系研究的新领域。国外学术界围绕地区间主义的内涵与外延、动力与功能以及其与地区主义和多边主义的关系进行了初步的研究。尽管国内学者在该领域的研究仍在相当程度上延续着西方的议程,然而也有部分学者试图在研究对象、研究方法和研究取向上做出超越。就该议题的未来发展而言,比较分析和理论化应当是两大基本趋势。而对中国学者来说,面临的最大挑战在于把握地区间主义研究的共性与个性,并善于从已有的研究议程中提炼出符合中国国家利益和国际战略需求的新的议程。 相似文献

Toxicology and fly larvae on a putrefied cadaver 总被引:2,自引:0,他引:2
Toxicological analyses on a putrefied cadaver are sometimes difficult to achieve, due to the absence of blood and/or urine. In this study, morphine and phenobarbital were simultaneously identified and assayed in several tissues of a putrefied cadaver and in the fly larvae of Calliphoridae found on the corpse. 相似文献

In the past decade, Latin America has emerged as the epicentre of participatory democracy innovations. Proponents argue that participation should lead to more equitable access to public goods and a greater sense of political efficacy. There has been considerable debate in the academic literature and in the public sphere over the extent to which participation can produce these benefits. Yet, while Latin America has witnessed an explosion of participatory mechanisms and related academic attention, the literature has focused on socioeconomic dimensions. There has been little attention paid to the experiences of racialized groups, such as indigenous peoples and Latin Americans of African descent. Research suggests that in order for participatory mechanisms to produce positive outcomes, they must be inclusive and offer participants a forum for real deliberation, but how do groups that have faced barriers related to racism and discrimination engage in these initiatives? Drawing on evidence from indigenous Ecuadorian and Afro-Venezuelan citizen participants, this article argues that participatory mechanisms may reproduce the very types of inequalities that representative institutions are criticized for. Comparing cases across and within different jurisdictions reveals that certain conditions enhance the ability of ethnic minorities to benefit from involvement in participatory mechanisms. 相似文献
