This article reviews the nature of discussions at the 1998 UN Technical Symposium on International Migration and Development. The Symposium reviewed the literature linking migration and development and successful policy approaches. Several themes emerged. A research framework is needed for accounting for all types of population mobility at all stages of the migratory process. Research should integrate contributions from a range of disciplines. The influence of social networks and cultural capital has grown in importance. Strategies need to account for women's experiences, which involve both empowerment and exploitation. Strategies need to consider return migration and better public information on migration and settlement. It was agreed that there is a need for a variety of quantitative and qualitative approaches and multidimensional analysis. The links between migration and development are complex, but sufficient information is available to greatly improve policy formation and international cooperation. National level responses have occasionally eroded the rights and protection of migrants. Few countries have adopted the 1990 UN Convention on the Rights of Migrant Workers and their Families and ILO Conventions 97 and 143. A prominent realization was that international cooperation did matter. International migration should be viewed as an opportunity for cooperation and development.  相似文献

The patterns of family formation and fertility behavior of Turkish and Moroccan women in Belgium are changing rapidly. The census data (1991) indicate a fertility decline. The reasons are changes in the nuptiality patterns, contraceptive behavior, and migratory flows. The changes are not identical in both communities. Young cohorts postpone their marriage, but this is most prominent among Moroccan women. On the other hand, young Turkish women have a clear preference for smaller families. The changes also differentiate according to migrant "generation" and level of education. The changes are not restricted to Belgium but are also observed in the countries of origin.  相似文献

"Debates about United States border control policies have generally ignored the human costs of undocumented migration. We focus attention on these costs by estimating the number, causes and location of migrant deaths at the southwest border of the United States between 1993 and 1997.... Deaths from hyperthermia, hypothermia and dehydration increased sharply from 1993 to 1997 as intensified border enforcement redirected undocumented migration flows from urban crossing points to more remote crossing areas where the migrants are exposed to a greater risk of death."  相似文献

Randomization of program participants into control and experimental groups is often not feasible in field settings. The researcher's desire to evaluate a program with a rigorous experimental design is often incompatible with the objective of serving the expressed needs of the program participants. However, opportunities do arise when a randomized control group can be constructed without disregarding the participants' wish to be included in the treatment group. This article describes a method that uses the participants' compliance to program instructions as a means of classifying participants and, thereby, obtains a randomized control group for a subset of participants. A large smoking intervention project is used to illustrate two variations of this method.  相似文献

Many sociologists believe in the myth of a Chicago School, a unified and coherent body of thought and research practice carried on at the University of Chicago from the 1920s through the 1960s. Chicago never constituted such a coherent system and is better understood as a school of activity, a group of people who cooperated in the day-to-day running of a major department.  相似文献

The probabilistic analysis of testimony is surveyed. The coverage is not comprehensive; attention is focused on several problems of particular interest or complexity. The theory often contains implicit assumptions, and some attempt is made to clarify the role these play. The theory originally arose in an attempt to understand the logic of belief. It was not empirically grounded, however, and later died out in the 19th century when its conclusions became largely self-evident, and its non-empirical background suspect.  相似文献

Kleinian theory seems both intimidating and alien to many American psychotherapists. This paper offers an entry into Klein's work. The theory is approached by emphasizing three areas especially valuable in clinical practice: mourning and manic defenses, schizoid relationships, and envy and idealization. A detailed presentation of an individual psychotherapy case is offered as an illustration of how her ideas may be integrated into a broader objectrelations treatment perspective.  相似文献

Relationships among three motivational variables (negative-personal functions of drinking, alienation, and perceived discrepancies between valued goals and expected success toward valued goals) were evaluated in a group of 257 college drinkers. As predicted, a positive relationship between alienation scores and the extent of discrepancies between values and expectations for academic and social success was found. Negative-personal drinking functions were positively associated with both alienation and value-expectation discrepancies. Results are discussed in terms of heuristic consistency and potential applications.  相似文献
