Schools are centers of collaboration in promoting the development and learning of children and adolescents. They seek to develop cultures of collaboration not only within their walls but also among constituencies with similar interests. These efforts, unfortunately, all too often prove frustrating and disappointing to all concerned. Yet, the need for interdisciplinary inquiry is greater today than ever before. This is particularly true considering the complex, diverse, and multifaceted nature of today's schools. No one professional can address all of the problems confronting education, particularly those of urban schools. For decades mental health and education professionals have joined together around their similar interest in promoting children and adolescent development. One such initiative is a program that fosters educators' development. This program, named the Teacher Education Program, began under the auspices of the Chicago Institute for Psychoanalysis and evolved into the Human Development and Learning Program when a partnership was formed with DePaul University's School of Education. From the program's 34-year history, the authors highlight specific tensions they experienced as directors of this collaborative initiative, and how these challenges either were or were not anticipated and/or addressed. The aims are to put a human face on the challenges and struggles encountered in the relationship between education and mental health professionals, and to identify common ground between educational and psychoanalytic theories and practices.  相似文献

Responses to the Adult Career Concerns Inventory (ACCI: Super, Thompson, Lindeman, Myers, & Jordaan, 1988) were organized through cluster analysis to identify different ways in which adults use exploratory behavior to cope with career development tasks. Significant differences in life-role salience among the types of adult career explorers identified were also investigated. Findings indicated a variety of ways in which adults use exploratory behavior. However, no significant differences were found in life-role salience among the types of career explorers. The discussion explains how career counselors can interpret their clients' ACCI profiles to select appropriate career interventions.  相似文献

This study explored the relationship between US immigration laws and their impact on the immigration of Asian professionals. The article relied on a 1996 Population Association presentation. Data were obtained from the US Immigration and Naturalization Service on legally admitted immigrants to the US. The authors describe the paths to admission, trends in immigration of professionals during 1972-94, and the Immigration Act of 1965 and its 4 amendments. Standardization-decomposition techniques are used to explain the relative differences in professional immigration across 1972-77, 1978-91, and 1992-94. The crude professional rate for all Asians declined by 19% during 1972-91. 62% of the decline was due to changes in the class of admission composition, and 25% was due to a decline in the class-specific professional rates. During 1992-94, the Asian crude professional rate increased 7%, most of which was due to changes in class composition, with the exception of Korean rates. Only the Vietnamese experienced a decline in rates. The 1965 law allowed for equity between countries in admission. The paths of immigration were family ties, job skills, or refugee status. During 1972-77, Chinese took advantage of family reunification, and Indians entered on employment preferences. The legal changes affected the size and share of each class of admission. The revisions indirectly affected the occupational selectivity of immigrant groups. 27% of the flow of Asians during 1972-77 was accounted for by employment preferences. Professionals were 44% of Asian immigrants during 1972-77, 26% during 1978-91, and 33% during 1992-94.  相似文献

"The present paper attempts a critical review of the data systems of seven major labour-exporting countries--Bangladesh, India, Indonesia, Pakistan, Philippines, Sri Lanka and Thailand--which account for over 90 per cent of labour outflows from Asia....Data...are discussed under separate sections focusing on limitations as well as potential for further exploitation.... For all countries reviewed here, these data significantly understate total labour outflows, and the magnitude of the error seems to vary between countries and reflect both differences relating to the coverage and efficiency of the approval and monitoring procedure. This throws serious doubts on the appropriateness of official outmigration series for cross country comparison. Frequent changes in reporting procedures also make for discrete changes and spurious shifts in data which render trend analysis quite hazardous." (SUMMARY IN FRE AND SPA)  相似文献

This paper develops a model ofinter vivos gifts and bequests in a setting of moral hazard and adverse selection. Altruistic parents do not perfectly know how much effort their children make to earn their living, nor do they know their true level of ability.Inter vivos gifts take place prior to the realization of the children's earnings whereas at the moment of bequests, parents do observe them. We show that an optimal transfer policy generally uses a mix ofinter vivos gifts — deemed as more efficient — and bequests — deemed as more redistributive.We are thankful to Allessandro Cigno, Jacques Cremer, Claude d Aspremont and anonymous referees for their comments.Responsible editor: Alessandro Cigno  相似文献

What do Florida sunbathers, midwestern farmers, rural black men, and Long Island women have in common? They all have higher-than-average risks for certain cancers. Researchers know that cancer clusters are usually caused by several factors. As cancer becomes America's leading cause of death, the public will be keenly interested in sorting out the causes and reducing the risks.  相似文献

This article develops a theoretical framework explaining the influence of economic conditions on rural-urban migration in tropical Africa. The model explains the continued process of migration despite high levels of urban unemployment. A lengthy discussion is devoted to short-, intermediate-, and long-term policies for relieving the urban unemployment problem. It is argued that efforts must be made to reduce the differences between the expectation of urban income and real rural income. No one single policy will slow rural-to-urban migration. The author suggests policies that would eliminate factor-price distortions, restrain urban wages, redirect development toward concentrated and comprehensive programs of rural development, resettle and repatriate unemployed urban migrants, and establish capital-goods industries. The capital-goods industries would develop labor-intensive technologies for agriculture and industry. The theoretical model assumes that migrants make decisions about moving on the basis of an expected income and the expectation of an urban job. It is argued that the urban-rural income differences and the probability of securing an urban job determine the rate and extent of rural-urban migration in Africa. If the migrant has a low probability of finding regular wage employment in the short term, but expects the probability to increase over time, the migrant would make a rational decision to migrate. Policies that operate solely on urban labor demand are considered unlikely to reduce urban unemployment. This model better estimates the shadow prices of rural labor.  相似文献

"This essay applies the theories of Ulrich Beck...to the politics of migration in Germany. In particular, the essay focuses on Beck's notion of the waning influence, indeed even relevancy, of science and scientists regarding postmodern risk phenomena. The essay argues that migration to Germany can be understood as a Beckian risk phenomenon, helping to explain the decreasing influence of social scientists over the politics of migration in the Federal Republic."  相似文献

Women in many countries of southern Africa do not have majority status or have only recently gained this right. Majority status grants individuals adult legal status and the right to bring matters to court, own and administer property, have legal custody of children, and contract for marriage. This article summarizes the legal status of women in Botswana, Lesotho, South Africa, Swaziland, Zambia, and Zimbabwe. Lack of majority status contributes to the ongoing risk of poverty for women and makes them overly dependent on men. Compounding the situation in these countries is the presence of a dual legal system. Improving the situation of women and their families involves targeting changes in the legal system, influencing implementation of laws, educating women about their rights, and giving women needed support to seek their legal rights. The legal status of women must be viewed in the context of historical changes in the economic, educational, political, and cultural developments of society.The research for this paper was conducted during her previous faculty affiliation with the University of Michigan, School of Social Work. Her research interests include the impact of social change on women and families, rural mental health services, and health and mental health linkages. She received her Ph.D. from Rutgers University and her M.S.W. from the Columbia University School of Social Work.Her research interests are gender, work and family, culture and power, social transformations in rural and peri-urban communities, critical education, women and community politics, history of women, family and kinship issues, and community-based program development and evaluation. She received her M.S.W. from Dalhousie University, Halifax.  相似文献
