This article examines the origins of physicians and nurses who were admitted as permanent immigrants to the US from 1962-1979. Data are mainly from the Immigration and Naturalization Service. Countries used in the developmental analysis are only those whose population was estimated at 1 million or more as of mid-1979, encompassing 99% of the physicians and 97% of the nurses. Life expectancy at birth is the criterion used to differentiate origin countries by developmental dimension of health status. During the study period, health workers constituted about 30% of immigrants admitted to the US; of these, nurses and physicians constituted 72-82% throughout the study period. The period 1962-1979 has 4 distinct phases, marked by important legislative and/or policy changes; 1) 1962-1965, when the McCarran-Walter Act prevailed; 2) ending in 1968, the 2nd phase covers the transition mandated under the 1965 Immigration Act, which encouraged physician immigration; 3) the 3rd phase, 1969-1976, covers the transition to the 1976 Immigration and Nationality Act amendments; and 4) the 4th stage is 1977-1979. Results show that 1) under the McCarran-Walter Act, North America became the dominant physician source; 2) from 1966-1968, Asia attained dominance as the physician source and became even more predominant after 1968; 3) North America produced relatively few physicians in the early 1970s; 4) Europe produced substantially fewer physicians in the 1970s than in the 1960s; 5) South America, Africa, and Oceania were the lowest contributors of physicians; 6) during the McCarran-Walter years, North America and Europe produced almost 90% of nurses admitted into the US; 7) the 1965 Immigration Act and its aftermath resulted in Asia becoming the dominant source of nurses; 8) prior to the 1965 Immigration Act, Canada generated 20% of the aggregate number of physicians; 9) the Philippines surpassed Canada during the transition and India led after the transition; and 10) Canada supplied 30% of the nurses up through the transition, with the Philippines in the lead 1969-1979. Low health status countries were a relatively minor nurse source. Health status at the origin was a far less significant determinant of physician immigration than that of nurses. English language high and low health status country groups produced substantially more physician and nurse immigrants that their corresponding non-English language counterparts. The US attracted more physicians and nurses from less developed countries than more developed countries after 1968.  相似文献

Compliments are often viewed primarily as a linear event in which one person expresses approval or admiration of another. Far less attention has been given to the circular nature of compliments and the manner in which they enhance the positions of both the giver and the receiver of the compliment. Therapeutic compliments have proven to be highly effective means of motivating clients, while at the same time increasing therapeutic leverage. This article proposes that compliments should be purposefully given, and that the type of compliment should vary with the stage of therapy and the intended response of the client to the compliment.  相似文献

Research on family therapy training has produced very little data regarding the kinds of trainees that do best in family therapy training programs. This study attempts to provide some rough and preliminary data on that issue. One hundred and seventy trainees, drawn from seven different structural!strategic training experiences, were evaluated as to how much they learned by taking the Family Therapy Assessment Exercise pre- and posttraining. Their performance was correlated using a hierarchical regression analysis with a number of trainee variables such as amount of conjugal family experience, amount of experience doing family or individual therapy, or prior knowledge of family therapy. The results indicate that, as predicted, conjugal family experience was positively related, and prior knowledge was negatively related to performance. Prior experience doing individual therapy was also positively related to performance.  相似文献

Recent research on the impact of labor migration on the socioeconomic development of developing countries has provided opportunity to try and resolve some of the long-standing polemics that have pervaded the literature on migration and development. This article focuses on findings concerning the labor, remittance, and social impacts of emigration on countries that have participated in labor emigration. While a great deal more research needs to be done, recent findings confirm that in some situations the sort-term impacts of labor migration on sending countries have been considerable.  相似文献

In this issue is a lengthy, thought-provoking essay on the issues raised by unwanted pregnancy. Written by Robert Wennberg in 1984 for the Christian Scholar's Review (13:4), the article has been edited and condensed for our purposes and is quite relevant, I believe, for the student health population. Any practitioner who cares for students wrestling with these issues should at least acknowledge the moral and philosophical dilemmas presented. As one who has walked both sides of the argument, I find Wennberg's fair-mindedness compelling. In closing his article, the author raises the question of what will happen when it becomes possible to accomplish an "abortion"--or removal of the fetus from the mother--without killing the fetus. Will this procedure be acceptable to the average single college student? The New York Times, in an article on "High Tech Babies" (February 21, 1986), raised ethical questions posed by the technology of frozen embryos. Who decides what is to be done with frozen embryos? To whom do they belong? Do they have rights? The theoretical issues raised by Wennberg are already forcing themselves upon us. Whether we like it or not, the future is now. Regardless of your beliefs on this controversial topic, I urge you to read this article. Dr. Wennberg has also just completed a book on this subject, Life In The Balance.  相似文献

Mandal, a church-related non-governmental voluntary agency operating in north-west India's Nasik district since 1966 was evaluated for performance in promoting self-sustaining economic growth and socio- political awareness in its beneficiaries. The research design incorporated 2 questions, the extent to which Mandal had used the integrated approach, and the extent to which it promoted structural change in the village. 2 levels of analysis were used: random samples of 315 individuals (163 beneficiaries and 152 non-beneficiaries) and data from the takatu's office for 20 involved villages and 8 control villages. Quantitative data were sought by examining files and doing closed interviews, and qualitative data were collected by observation and open-ended interviews. The variables used in the analysis were educational level, class category, caste, agricultural investment, family net income, individual consciousness and social participation. It was concluded that on the individual level some positive impact was discernible in terms of family income and agricultural investment. At the village level no quantitative improvement was measurable, but the effect of Mandal was symbolic in that it sets an example for social change. The Mandal has acquired a health, non-partisan secular image for social action.  相似文献
