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

Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome
studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing
child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management,
self control, stimulus control, communication and child management skills training exercises, and financial management components.
Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated
by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her
responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental
control and follow-up data collection) of this case example are discussed in light of these results. 相似文献

The Chinese understand food. We all need to eat; people share food to become intimate with others, and food represents comfort and nourishes our bodies. Westerners sometimes forget the medicinal value of food but Chinese people understand this well. They gratify themselves by eating but many of my Chinese friends also choose medicinal meals, either through traditional doctors, or via recipes, to focus on maintaining a balanced body. At the same time, eating 相似文献

Abstract The expansion of the security agenda after the end of the Cold War, propelled by the blowback of 11 September 2001, raises questions about the German ability and willingness to contribute to the regional and global security governance tasks facing Europe and Germany's continuing fidelity to its post-war European avocation. It also calls for a reconsideration of the Birmingham model of foreign policy analysis, particularly its emphasis on (and interpretation of) the ideational and institutional factors defining the German foreign policy agenda and shaping German foreign policy behaviour, at least with respect to the implementation (rather than formulation) of European Union security policies. Towards assessing the continuing utility of the Birmingham model, this article proceeds in three steps: the presentation of the Birmingham model and its restatement as six conjectures; a discussion of the security governance functions undertaken by the EU and the collective action problem facing Europe (and Germany) in executing them; and an empirical investigation of Germany's contribution to the EU as a security actor since 1990. 相似文献

DNA-based identification of forensically important Chrysomyinae (Diptera: Calliphoridae). 总被引:6,自引:0,他引:6
Identifying an insect specimen is an important first step in a forensic-entomological analysis. However, diagnostic morphological criteria are lacking for many species and life stages. We demonstrate a method for using mitochondrial DNA sequence data and phylogenetic analysis to identify any specimen of the blow fly subfamily Chrysomyinae likely to be collected from a human corpse within Canada or the USA. The reliability of the method was illustrated by analyzing specimens designed to mimic the information likely to be obtained from highly degraded specimens as well as specimens collected from widely separated geographic locations. Our sequence database may be suitable for another country provided the investigator knows the local fly fauna well enough to narrow the choice of chrysomyine species to those used in this study. 相似文献

The events of 1989 have raised questions about NATO's future and purpose. Two different views are held by Germany and the USA. The Germans seek the political and economic unification of the EC, the construction of a European pillar within a demilitarised NATO, and a pan‐European collective security system. In contrast, the Americans seek to preserve NATO as a military alliance responsible for western European security under American leadership and to equip NATO with competences extending beyond the NA TO area. Whilst insisting on greater western European burden sharing and security coordination, the Americans see the roles of the CSCE and the WEU as complementary to NATO's. 相似文献
