The growing concern with illegal, or undocumented, migration in developing countries is described. The author notes that although such migration occurred in the past without causing concern, changing economic, political, and social factors since the 1970s have caused governments to attempt to control such flows. A review of regional trends is included, and the consequences of illegal migration for both countries of origin and destination are examined. (SUMMARY IN FRE AND SPA)  相似文献

"This article examines the incidence of [job-related] transfers in Malaysia. The retrospective migration data from the Malaysia Family Life Survey [conducted in 1976-1977] are used to demonstrate that transfers comprise 18 percent of all migration in the country and that there has been a rise in the incidence of transfers over a 35 year period. Factors underlying this trend are outlined. Furthermore, significant differences in age, educational attainment and other characteristics between transferees and other types of migrants are identified and their implications discussed."  相似文献

This article deals with all levels of both living (biological, psychological, sociological, and cultural) and nonliving (physical, chemical, and mathematical) systems. The idea of applying the natural scientific self-organizing, evolutionary, and non-equilibrium or "chaos" theory associated with the names of Prigogine and others to world problems of impending social, political, economic, and ecological "chaos" is gaining ground. The leap from natural science to social action, however, is impossible without considerable attention to the main intervening step: the development of "chaos"-equivalent, evolution-, systems-, and action-oriented social theory. Construction of such theory requires understanding by social scientists of natural scientific "chaos" theory as well as their own "chaos" theoretical heritage, of natural scientists of the now seemingly far distant social problem-solving potential of their nonequilibrium and self-organizing theories, and of both natural and social scientists of how advancement at both levels could help gain a peaceful as well as humanistic "order out of chaos" in this troubled world of ours. This paper surveys relevant concepts, problems, theorists, research, and works in progress within a perspective of the challenge of survival at a critical juncture in the evolution of our species.  相似文献

Mortality trends in the USSR from the middle of the nineteenth century to the present day are analyzed, with a focus on changes in life expectancy. The authors note that life expectancy increased up to 1964-1965, declined subsequently, and stabilized during the 1980s. Life expectancy has again started to rise since 1985. More detailed analyses of mortality differentials by sex and age and for the rural and urban populations are included. (SUMMARY IN ENG)  相似文献
