[Medico-genetic study of the population of Turkmenia. V. A population and demographic description of the Nokhur isolate].

The paper deals with demographic, genealogical and genetic characterization of one Turkmenian isolate--"Nochur". The data on its load of hereditary diseases were published previously. The Turkmenian "Nochurly" tribe consists of 19 large and small clanes. 600 nuclear families live in a small mountain valley of the same name. The share of prereproductive age class is 60%, of reproductive class--29%, this value for postreproductive class being 11%. The average number of children per family, when the families have completed their reproductive period, is 6.84. The average duration of generation (the mean parental age to the birth time of a mean newborn) is 37.7 and 31 years for a man and woman, respectively. Immigration into Nochur is practically absent, there is a flow of emigrants to the capital of the Republic, Ashkhabad. A very high level of assortative mating has been noted, the minimal estimation of inbreeding coefficient being 0.033 (the pedigree) and the maximal--0.0529 (isonimy). Diminishing of the number of lethal equivalents between 1940-1965 and 1966-1980 was discovered. This can be explained by a decrease in natural selection pressure. The data on distribution of genetic markers of the ABO, MN, Rh, Hp and Pp systems within this isolated population are presented.

Immigration-associated variables and substance dependence.

OBJECTIVE: Drug-dependent patients show increased negative mood states such as anxiety and depression that interact with drug craving and quality of life. In this study, we compared immigrants with and without drug dependence and assessed whether drug dependence and social status after immigration contributed independently to negative mood states, stress-coping strategies and satisfaction with life in Germany. METHOD: Immigrants (N = 80) who had emigrated from the former Soviet Union to Germany were participants in the study. Drug-dependent immigrants (24 men, 16 women, mean [SD] age 33 [9] years) were compared with healthy immigrants (26 men, 14 women, mean age 35 [12] years) on current emotional status, trait-anxiety, depression, stress-coping strategies, drug craving and immigration-associated data. RESULTS: Compared with healthy immigrants, drug-dependent immigrants showed significantly higher levels of anxiety, depression and negative stress-coping strategies, independent of differences in education or employment status. Satisfaction with being in Germany was associated with both drug dependence and employment status. The severity of drug craving was significantly associated with negative mood states but not with any other measured sociodemographic variable. CONCLUSIONS: This study shows that drug dependence is associated with increased negative mood states and poor stress-coping strategies, independent of the assessed sociodemographic variables. Drug dependence may thus severely interfere with acculturation in the host country. Because immigrants often face reduced treatment options as a result of cultural and language barriers, our findings underline the importance of adequate drug treatment facilities for dependent immigrants.

Economic deregulation and changes in New Zealand's immigration policy: 1986 to 1991.

"New Zealand's immigration intake is small by the standards of the main immigrant receiving nations and many of her immigrants are subsequently lost through the process of re-emigration. Nevertheless, changes in New Zealand immigration policy over the last 10 years have been profound. This article is the first of a two-part history of these changes."
