Ultrasonic determinations were made of facial tissue thicknesses in 50 healthy American caucasoid children, ranging in age from 4 to 15. Twenty measurements were taken at sites along the median, right sagittal, and right lateral planes. A static scanner was used in the B-mode. Three measurements significantly increased with age, the mid-philtrum (rs = 0.43, p less than 0.01) in females, the mental sulcus (rs = 0.30, p less than 0.05) in males, and the frontal eminence (rs = 0.32, p less than 0.05) in both sexes. Moreover, 25% of the measurements, while not statistically significant, decreased with increasing age. These data provide a basis for facial reproductions in caucasoid children. 相似文献

The present experiment investigated the role of emotions and perceptions in determining the overt behavior of disadvantaged group members. Three limitations to the existing psychological research are presented as a possible reason for the present inability to describe a consistent relationship between the emotions and perceptions of those faced with intergroup inequalities and their subsequent actions. The present experiment attempted to address these limitations by employing a laboratory paradigm in which subjects actually engage in overt behavior. As well, a broader array of emotions and perceptions were assessed and subjects were offered a variety of behaviors from which to choose. The findings point to a relatively strong relationship between emotions and perceptions on the one hand, and overt action on the other. Feelings of frustration and anger, the perception of one's personal treatment as satisfactory and just, and hope of future improvement of one's position combined to discriminate between subjects who accepted their disadvantaged position, those who took normative forms of action, those who reacted in an individual nonnormative way, and those who chose collective nonnormative behavior. 相似文献

Using recent citation analyses of criminology journals and textbooks to estimate the “match” between what journals report
and what textbooks discuss. Twentythree criminology textbooks published from 1989 to 1993 were ranked by how prominently they
cite the 25 most-cited scholars in recent leading criminology journals. I suggest some reasons why criminology textbook authors
extensively cite and discuss some influential scholars but not others, and conclude by noting several limitations to using
citation analysis to estimate the match between journals and textbooks. 相似文献

Age estimation from the rib by phase analysis: white females 总被引:4,自引:0,他引:4
Metamorphosis at the sternal extremity of the rib has already been established as a reliable indicator of age at death. Using a sample of white males, it was shown that an accurate estimation of age can be made by direct examination of the bone itself. However, because of sexual differences in hormonal production and dimorphism in the skeleton, the present study was carried out to develop an appropriate standard for age determination from the sternal rib in white females. The sample consisted of 86 ribs of known age, sex, and race. Observations were made at the costochondral junction with special attention to pit formation (its shape and depth), changes in the walls and rim surrounding it, and overall bone density and texture. Based on changes in these areas, the ribs were separated into nine phases (0 through 8). The most rapid metamorphosis occurred in Phases 1 through 4 (mean ages 14-28) with changes noticeable at 3 to 4 year intervals. After mean age 28, this process slowed, considerably expanding the interval between phases to 10 to 15 years. The female ribs showed both earlier initial pit formation and a different morphologic pattern of aging as compared with males. Statistical analysis revealed that the features chosen to delineate the phases are valid predictors of age. This study has shown that the sternal rib can provide an accurate estimation of age in females spanning a mean age of 14 to 76 years. 相似文献
