Allele frequencies for 16 previously described autosomal SNPs were tested in 1020 unrelated individuals originating from three different continents (Africa, Asia and Europe). The populations analyzed included Africans from Benin Gulf (180), Asians from Mongolia (160) and Europeans from Italy (680). 相似文献

Using four years of household data from three agroecological zones in Burkina Faso ‐ Sahelian, Sudanian, and Guinean ‐ the article examines the determinants and effects of household income diversification. Harvest shortfalls and terms of trade are found to drive diversification, but land constraints do not. Income diversification is associated with higher incomes and food consumption, and more stable income and consumption over years. 相似文献

Although the acculturation gap generally has been associated with poor mental health outcomes among Asian American children,
some studies have failed to find a significant relationship between the gap and distress. Using two different methods of operationalizing
the gap between mothers and their children, the current study addressed this tension in the literature by testing the following
hypotheses in a sample of Korean American families. It was hypothesized that mother–adolescent discrepancies in acculturation
and enculturation levels would be associated with youth internalizing and externalizing symptoms and that parent–adolescent
communication would moderate the gap–distress relationship. Multi-informant questionnaires were administered to 77 Korean
American mother–adolescent dyads from the Midwest. Surprisingly, results indicated that consonance in low levels of mother–adolescent enculturation was associated with the highest levels of externalizing symptoms (interaction term method). Adolescents’ perception of communication with their fathers significantly
moderated the relationship between the enculturation gap and internalizing symptoms, such that in dyads with a greater enculturation
gap, less perceived open communication with fathers was associated with more internalizing symptoms (difference score method).
Clinically, the findings indicate a potential target (i.e., parent–adolescent communication) for treatment programs that aim
to improve family relations and youth adjustment in immigrant families. 相似文献

As the various categorical programs of federal assistance proliferated during the 1960s and 1970s, the U.S. government sought to bring about some degree of coordination among the programs in any given region through a network of regional clearinghouses. Operating with inadequate resources, limited authority, and various other difficulties, the clearinghouses nevertheless chalked up some modest accomplishments. In 1982, as a step in the New Federalism concept of the Reagan administration, the clearinghouse system was drastically shrunk back in scope and decentralized in structure. If the concept of regional coordination among federal programs is to survive, it will have to depend on action at the state and local levels; but such action does not seem promising. 相似文献
