This paper focuses on the trafficking and smuggling of human beings fromand through the former Soviet Union. It explores the reasons for the risein the illegal movement of people; the groups which facilitate it; the demographics of the people who are moved and the business side, includingthe profits, the disposition of profits and the use of corruption to facilitatethe trade. With the disintegration of state control over national territory, this mass movement of people often violates national laws and the national sovereignty of the countries of the Soviet successor states and the countrieswhere the former Soviet citizens move illegally. The paper concludes that thistrade mirrors and contributes to the overall downward development of thepost-Soviet economies. In contrast, a comparative look at the respective Chinese developments indicates that trade in human beings tends to facilitatethe growth of both the Chinese legitimate and illegitimate economies.  相似文献

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
