The ability to utilize metaphor is presented as the normal stage in the development of the capacity to symbolize that is characteristic of the young adolescent. Symbolization is considered to be the basic structure through which the individual constructs a knowledge of the reality and of the self. Therefore, staying within the framework of the metaphor in treatment with the young adolescent is beginning where the client is but equally as importantly it is assisting the youngster to further develop both his symbolic capacities and himself. A case illustration is utilized to demonstrate both healthy and pathological usage of metaphorical language.  相似文献

The authors describe a project, begun in 1981, to locate, list, and annotate all the published work based substantially on the census enumerators' books for nineteenth-century censuses for England and Wales. The results are currently available in a computerized file, enabling a variety of searches by topic, geographical area, and type of population. Information is provided on using the data and the computerized bibliography. The authors note that, subsequently, data for censuses of Scotland and Ireland have been added.  相似文献

This paper describes the major structural and historical dimensions of health ideology and praxis in the Canadian Arctic. It examines the problems that occur when primary care services exclude their clients from meaningful involvement in planning and administration. It argues that the structure of health services in northern Canada reflects an internal colonial political economy which is characteristic of most Fourth World situations.  相似文献

"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

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 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

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
