Postmortem decay causes fingertip decomposition, desiccation, shriveling, and rigidity, reducing the possibility of obtaining sufficiently clear fingerprints for identification. In this study, five rehydration solutions (ammonium hydroxide, sodium carbonate, potassium hydroxide, urea, and warm water) followed by three fingerprint recording methods (photograph, inking roll, and dusting tape) were investigated to process mummified fingertips from an unidentified cadaver. The results show that sodium carbonate treatment is the most effective for minutiae restoration, followed by ammonium hydroxide treatment. This study also demonstrates that even those fingertips that previously failed in urea solution, 1% potassium hydroxide solution, and warm water treatment could be further improved with sodium carbonate solution to obtain qualified minutiae for fingerprint matching. The optimal procedure is rehydrating the desiccated fingertips with sodium carbonate solution for 24 h followed by dusting the finger and transferring the print to adhesive tape.  相似文献

Traditional nonmetric methods of ancestry assessment posit orbital rim shape varies among ancestral groups. This pilot study uses morphometric analysis of 3D orbital variation to test discrimination among individuals of primarily European, African, and Asian ancestry. Although the size and nature of the sample analyzed limit inferences for other samples, principal components analysis suggests ancestry has a significant effect on rim shape (p = 2.93e‐04). European orbits display more marked folding of the orbit in the sagittal plane than either African or Asian orbits, while the lateral margin of African orbits lies further posterior relative to the medial margin when compared to Asian orbits. The findings suggest curviplanar relationships are the most ancestrally informative aspect of orbital rim shape; these relationships may be distorted by perspective based on orientation of the skull relative to the viewer in traditional nonmetric analyses. Additional studies on geometric morphometric approaches to ancestry assessment are therefore warranted.  相似文献

Interpreters play an important role in police interviewing witnesses from culturally and linguistically diverse backgrounds. In the cases where interpreters lack professional attributes such as interpreting competence and impartiality, it is very likely that the interpreted evidence and statement will not be a faithful reproduction of original utterances. If attention is not paid to possible alterations by interpreters to the original utterances of the witness and duty of care is lacking in the procedure of obtaining statement from witnesses through such interpreters, the official legal record may not be an accurate one. Drawing on the data of a video-recorded interpreter-mediated police interview in South Korea, this paper examines issues arising from the lack of understanding of the role of interpreters, which may have implications for criminal proceedings. The findings indicate that in addition to interpreter training, more efficient police training in the adoption of best practice guidelines in interviewing through interpreters is required.  相似文献

This paper explains how authoritarian regimes employ flawed elections to obtain both short-term legitimacy and long-term stability. In conjunction with the use of co-optation and repression, it argues that ruling parties hold de jure competitive elections to claim what is termed autonomous legitimation. This denotes the feigning of conformity to the established rules of the constitution and the shared beliefs of citizens. Regardless of overall turnout and support, ruling parties exploit the normative and symbolic value of elections in order to establish moral grounds for compliance within a dominant-subordinate relationship. In support of this argument, the case of Singapore's People's Action Party (PAP) is analysed in historical and contemporary terms. Since 1959, the PAP has used precisely timed elections to extract one or more mandate types from citizens and, by extension, claim legitimacy. In particular, it has sort a mandate based on its response to an event, execution of a policy and/or collection of a reward. In the long run, autocratic stability has been achieved through a process of reciprocal reinforcement, which has combined autonomous legitimation with targeted co-optation and low intensity coercion. The paper concludes by addressing the generalisability of this finding for other authoritarian regimes in Southeast Asia.  相似文献

Instrumentalism, the philosophy that rational people will behave in ways that promote self‐interest, is often the default assumption that scholars and practitioners rely upon when interpreting and predicting human behavior in negotiations. Instrumentalism, however, need not be the only lens through which negotiators and negotiations are viewed. In this article, we discuss some of the problems associated with too heavy a reliance on instrumentalism and propose an alternative relational approach, one in which negotiators see themselves as agents embedded in a system of relationships, who are motivated to understand and advance the welfare of others. We discuss some of the characteristics that differentiate negotiators who adopt a relational versus instrumental approach and invite scholars and practitioners to consider the implications of viewing negotiations through a more relational lens.  相似文献
