"This paper seeks to (1) identify socioeconomic variables that are expected to generate fertility differentials; (2) hypothesize the direction and magnitude of the effect of each variable by reference to a demand-for-children model; and (3) test empirically the model using evidence from Costa Rica. The estimates are obtained from a ten-percent systematic random sample of all Costa Rican individual-family households. There are 15,924 families in the sample...." The authors specifically seek "to capture the effects of changing relative prices and available income and time constraints on parental preferences for children. Least-squares estimates show statistically significant relationships between household fertility and opportunity cost of time, parental education, occurrence of an extended family, medical care, household sanitation, economic sector of employment, and household stock of nonhuman capital." 相似文献

An analysis of the foreign population in Kuwait shows that foreign nationals make up 60 percent of the population and 78 percent of the labor force in Kuwait. The implications of these figures for the Kuwaiti labor force are discussed by analyzing the occupational structures of Kuwaitis and non-Kuwaitis. "Structural analysis of the labor force indicates that 62 percent of Kuwaiti males are concentrated in administrative and service occupations while their percentage in sales and production work has declined during 1970-80. This demonstrates the need for reorienting educational/training programs and changing Kuwaiti attitudes towards manual work to ensure the realization of the 'Kuwaitization' process, and balance the nationals with foreign nationals." mortality has stabilized at relatively high levels and there is resistance to family planning. The author concludes that the main cause of the stalling of the demographic transition process is to be found in the role of the state and the dynamics of the social structure and that "demographic trends will depend more on the changes in social structure, land reforms, and response of the formal governing system to the needs of the underprivileged sections of the society, rather than on the health and family planning policies." 相似文献

This article examines interstate migration and labor force participation among White, American Indian, and intermarried Indian/White couples in the US. The results show that endogamous American Indian couples are much less likely to change states of residence than are the other 2 groups of couples. The effect of interstate migration on labor force participation does not vary across the 3 groups of couples. The implications of these results for the assimilation and internal colonial models of race relations and for federal Indian policy are discussed 相似文献

This study focuses on the brain drain of health care professionals and physical scientists from Argentina, using survey data on a group of 89 immigrants who are currently US residents and listed in the current edition of AMERICAN MEN AND WOMEN OF SCIENCE. Although the loss of educated people is probably more likely if their degrees are acquired abroad, even at the doctoral level, the majority of those responding held Argentine degrees. The most important motivation was to gain professional and career advancement. Although pragmatism was associated with the decision to emigrate, the political environment was also quite important. Responses indicate that the losses of scientific personnel which have occurred in the past may be irreversible. Most of the respondents have become US citizens and now have families in that country. However, many respondents still have family, friends, or professional associations in Argentina. Some subtleties bear mention. The retreat of the generals has not removed all political factors from the problem list. Now scientific and professional activities must be de-politicized. The government must take explicit steps to ensure that academic and scientific positions are awarded on the basis of expertise. The evidence suggests that educational considerations are far less important as a causal element in the brain drain from Argentina than is the case in many Third World countries. 相似文献

A scattering of recent research has studied the current politicalbeliefs and attitudes of individuals identified as "1960s activists."In contrast to much of the treatment accorded such people inthe popular media, this research tends to find most of theseactivists currently liberal on a wide variety of political topics.However, in the absence of panel data, most of this researchhas had to assess any change in the activists' attitudes eitherby assuming the activists' past positions or by trusting totheir retrospective reports. In this paper we report on panel data from a large group ofwhite activists, mostly students, who spent the summer of 1965organizing voter registration drives in Southern black communities.In some specific areas on which the activists tended to holdrather extreme positions in 1965, they may have moderated by1984. However, their overall pattern of response on a wide varietyof issues is basically stable over this twenty-year period. 相似文献

A typology of migration is presented that extends the one originally developed by William Petersen, which was based on ecological push, migration policy, people's aspirations, and social momentum. The proposed typology considers both the migrant's state of mind and two points in time. Examples of 36 migrant types are provided using data for Canada and selected other countries.

This article examines four issues that need to be explored by the therapist as possible causes of stress for a male couple: stereotypic male roles, stereotypic sexual roles, homophobia, which includes the "coming out" process, and sexual dysfunctions. These issues can cause anxiety and stress, which may in turn cause relationship problems for a male couple. The role of the therapist is clarified and suggestions for treatment are given. 相似文献

Chaos and transformation: implications of nonequilibrium theory for social science and society 总被引:1,自引:0,他引:1
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
