Using data from the 1976 and 1988 censuses, the author notes that the population of Senegal has grown by 37.6 percent over the period and that this growth is concentrated in urban areas. One feature of this trend has been the growing primacy of the capital Dakar and a decline in the relative importance of smaller towns. The need to discourage rural-urban migration by promoting socioeconomic development in rural areas is stressed. (SUMMARY IN ENG)  相似文献

In August 1992, a project team of senior medical and administrative personnel was formed (Housestaff Coverage Project Team) at the Park Ridge Health System, Rochester, N.Y.. The team was given a mandate to address housestaff coverage, primarily from an economic standpoint. Through total quality management (TQM), the project team sought to develop a house coverage plan that was sustainable, efficient, and effective. A plan was developed that includes three layers of service. A minimum "standard hospital coverage" would be available to all physicians and their patients and cover the basic needs of admission, crisis intervention, and issues of length of stay. A complete level of service would be available under the title of "case management" and would consist of total patient management, under the direction of the attending physician, from admission through discharge. The third level of service available to both "standard" and "case managed" patients would be a "consultative service." The latter would function as a traditional in-house medical service and would bill for its services. Park Ridge Hospital believes it has developed a system of housestaff coverage that is sustainable, efficient, and effective. An evaluation mechanism, primarily addressed at length of stay, will tell if we are correct in this assumption.  相似文献

A survey was mailed to 100 physician executives identified through the 1991 American College of Physicians Executives directory. The subjects were asked to rate 17 managerial areas on their value to the subjects' current work, on the subjects' preparation in the areas, and on the need for training in the areas. In addition, the subjects were asked how best to accomplish training in the areas and for a list of areas of greatest importance in the future for physician executives. The subjects rated communication skills, quality assurance, utilization review, and personnel management as being of primary value in their current roles. Preparation was most adequate in communication skills and most inadequate in the areas of finance and organizational management. Training was deemed desirable in all areas, but was thought to be most necessary in communication skills, negotiations, strategic planning, and organizational management. There was least desire for training in the areas of labor law and employment law. The most popular means of training were doing a fellowship in administrative medicine, receiving continuing education through seminars or workshops, or getting a degree in management.  相似文献

Findings are based on a sample of four types of Turkish women affected by migration: 1) pioneer women who emigrated on their own (33 persons); 2) followers with wage work experience, who joined or left with husbands (44 persons); 3) followers without wage work experience (39 persons); and 4) women left behind when husbands migrated (45 persons). These women are compared to a non-migrant control group (54 persons). Sample surveys were conducted in three sites, which varied in levels of industrial development, economic diversification, and urbanization (Ankara, Kisehir, and eight rural villages in the province of Kisehir). The sample includes returnees registered with the Social Insurance Institute and persons located by the chain inquiry method. Prior research supports the importance of including typologies based on family types, marriage types, levels of education, and experience with wage work. This study confirms that pioneer women were more likely to have romantic marriages, to have nuclear families, to have higher educational levels, and to have prior wage work. Analysis of the 116 women with migration experience shows that 75% migrated during 1968-74. 22% migrated after 1980. 51% were returnees during 1983-85, and many received retirement benefits. Almost 65% spent 10 or more years abroad. 56% were aged under 24 years. 85% were married at the time of emigration. 61% viewed their migration experiences as improving their maturity and ability to handle affairs compared to nonmigrant women. 88% became housewives after returning. 27% of return migrants and 82% of nonmigrants had never had their own bank accounts. 69% of return migrants and only 22% of nonmigrants reported movement outside the home without permission. 63% of migrants and 39% of nonmigrants would cast political votes independently of their husbands. Migrating women exercised more independent behavior but retained traditional responsibility for housework. The greatest differences were between women with wage work and women without or with migrating husbands. Followers without wage work were the most disadvantaged. Migration is viewed as a significant factor in determining gender roles among Turkish women.  相似文献

"Teacher, what are we going to do next class?" This is an exciting question which I often hear from my students. As an English conversation teacher, I can make the learning of English either a dull and boring duty, or an exciting adventure. It is very important that I make my students hate missing my class, and keep them guessing just what will happen the next time! Let us consider some important ways that any teacher can help his other students want to do their  相似文献

"This article examines the probable effects of the North American Free Trade Agreement (NAFTA) on migration from Mexico to the United States, disputing the view that expansion of jobs in Mexico could rapidly reduce undocumented migration. To the extent that NAFTA causes Mexican export agriculture to expand, migration to the United States will increase rather than decrease in the short run. Data collected in both California and the Mexican State of Baja California show that indigenous migrants from southern Mexico typically first undertake internal migration, which lowers the costs and risks of U.S. migration. Two features of employment in export agriculture were found to be specially significant in lowering the costs of U.S. migration: first, working in export agriculture exposes migrants to more diverse social networks and information about U.S. migration; second, agro-export employment in northern Mexico provides stable employment, albeit low-wage employment, for some members of the family close to the border (especially women and children) while allowing other members of the family to assume the risks of U.S. migration."  相似文献
