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

The Bilderberg group, which originated in Europe in 1952, slowly organized an American participation in the following two years. After a first conference held in May 1954, it rapidly developed into one of the most successful private transatlantic organizations of the 1950s. The project for an Atlantic Institute, which dates back to 1953–54, took longer to develop into a concrete institution, and was formally created, after several years of preparation, in January 1961. Both organizations received funding and support from the Ford Foundation and became fully-established fora in the early 1960s. The study compares the two initiatives to see how they shed light on the more general context of a ‘transatlantic culture’ in the Cold War. Although the networks of personnel were of a different nature and drew on different circles and professions, one can observe some interlocking, and their joint success in the early 1960s was partly due to their importance in ‘outflanking’ Gaullism in France. 相似文献

Low self-control has emerged as a consistent and strong predictor of antisocial and delinquent behaviors. Using the twin subsample of the National Longitudinal Study of Adolescent Health (Add Health), genetic analyses were conducted to examine the genetic and environmental contributions to low self-control and offending as well as to their relationship with one another. The results revealed that low self-control and criminal behaviors are influenced by genetic and nonshared environmental factors with the effects of shared environmental factors being negligible. In addition, the co-variation between low self-control and criminal behaviors appears to be largely due to common genetic and nonshared environmental factors operating on both phenotypes. The implications of these findings on the current understanding of Gottfredson and Hirschi??s general theory of crime are discussed. 相似文献

An alternate method for quantitation of human genomic DNA is presented. Quantitative template amplification technology (abbreviated "Q-TAT") estimates the quantity of human DNA present in an extract by comparing fluorescence in X and Y amplicons produced from unknowns with fluorescence in a standard curve amplified from known quantities of reference DNA. Q-TAT utilizes PCR and electrophoresis with fluorescent detection/quantitation, precluding the need for new instrumentation, methodology, or quality assurance associated with slot-blot or real-time PCR. In a comparison study incorporating shared samples, Q-TAT was found to be more sensitive than widely used slot-blot methods but somewhat less sensitive than real-time PCR. Among samples containing DNA concentrations ranging from 100 pg/microL to 2-4 ng/microL, Q-TAT produced DNA concentration estimates that agreed reasonably well with either Quantiblot or real-time PCR. Q-TAT was reproducible with a typical coincidence of variation of about 35%. Quantitation of human DNA in this study involved summing fluorescence in X and Y amplicons in unknowns and quantitation standards. However, analyzing fluorescence in X and Y amplicons individually could allow estimates of male and female DNA present in mixtures to be made. Moreover, since X and Y amplicons exhibit sizes of 210 and 216 bp, respectively, the integrity as well as the concentration of the genomic DNA template can be assessed. Q-TAT represents an alternate method useful for the quantitation of human genomic DNA prior to amplification of STR loci used for identity testing purposes. The method uses existing equipment and procedures in conjunction with a well-characterized DNA standard to produce concentration estimates for unknowns that reliably produce STR profiles suitable for analysis. 相似文献
