Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research. 相似文献

Informed consent and the changes in what is expected over the 21st century provide an instructive case study of the mutual influence on one another of medical law and medical ethics. Over the years we have moved from a doctor-centred standard to a patient-centred standard and from a one-size-fits-all patient-centred standard to a more individual requirement that engages with the needs of a particular patient It is unreasonable to expect those changes to be reflected in anything less than an extended conversation in which the health care professional gives out some version of what a reasonable patient would expect to hear from an informed health care professional and then responds to the patient's questions as informatively and helpfully as he or she can. It is therefore convenient to refer to spontaneous and responsive disclosure as a very concrete implementation of the health care professional-patient partnership that is contemporary health care and at the heart of health care ethics. 相似文献

This article addresses orientations towards place and opportunities for rural–urban and inter-regional migration amongst graduates of vocational colleges in Ul'yanovsk Oblast'. Given the inaccessibility of the housing market and decline in the provision of student and workplace accommodation, kinship networks have become the principal means to negotiate any form of migration. However, while in some cases such networks provide ‘bridges’ to opportunities elsewhere, a general lack of networks, alongside the ‘bonding’ effects of kinship networks at the local level, acts as a significant constraint on young peoples' prospects for geographical, and social, mobility. 相似文献

The production of culture in urban image-making has received much attention within geography. This paper intervenes in the culture–economy debates in a slightly different way—namely, through the lens of an understudied city of the global South. It examines the structure and discourses embedded in the Tijuana (Mexico) Municipal Plan 2005–07 to interrogate the work that culture performs with an eye to the impacts (both material and discursive) of official strategies across time and space. In so doing, two propositions are suggested. First, post-colonial spaces offer important sites from which to critique the conflation of cultural practice and policy. Secondly, the complex imbrication of culture and economy can be further distilled in grounding examples in ordinary cities. 相似文献
