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

Two questions concerning the location of a single facility by a voting process are investigated for transportation networks: - What is the maximum number of customers located on the network preferring some rival point over a voting solution? - How does the average distance of the customers to the facility increase when a voting location instead of a Weber location is chosen for the facility? Complete answers are given for general networks and for certain planar networks, viz., the so-called generalized cacti. 相似文献

Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion. 相似文献

This paper demonstrates the need for a broad array of clinical services in treating the emotionally disturbed, mildly retarded youngster in the foster care system. A hypothesis suggests that cognitive deficits and borderline pathology are interrelated, and that treatment involves modifications of traditional therapeutic techniques. The definition of clinical is expanded to include seemingly concrete and environmental services, in addition to the office therapy session. Finally, some systemic impediments to effective treatment of the population are explored.This paper was completed as a requirement of the Post-Master's Program in Advanced Clinical Social Work of Hunter College School of Social Work. 相似文献

This article describes the therapeutic use of canines in child welfare work. The chronically rejected child, or those who virtually spend their entire youth in care, tend to develop a withdrawn, depressed, and suspicious posture toward their relations with other people. This ultimately results in their failure to respond to conventional treatment modalities. Under these circumstances, the canine intervention may prove to be a valuable adjunct, helping to develop and to expedite the process of the therapeutic alliance.This article is a revised version of one presented to meet the requirements for the Masters in Social Work Degree from Hunter College School of Social Work. 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

Because of cultural, historical and other social structural factors, men and women with the same chronological age have had quite different career trajectories. This paper examines how the different career-paths of men and women academics create differences in their images of aging, self and work. In-depth interviews (N=47) were conducted with a sample of male and female professors, currently between fifty and sixty years of age. Male respondents nearly uniformly followed continuous, linear careers while the women's careers were, with equal uniformity, discontinuous. Data suggest that this difference in career routes fashions different gender timeclocks, i.e., different experiences of aging. 相似文献
