Elective single mothers are adult, unmarried women who intentionally become mothers. This study utilized longitudinal data about 17 Caucasian, elective single mothers and their children to identify fathers' roles in these families, and to understand children's views of their fathers. These single mothers and their children resided for the first six years of the children's lives in father-absent households. By age six, most of the children had ghost fathers, whom they had never met or knew little about. The data suggest that the father often becomes a family secret, and that children may blame themselves for their fathers' absence. 相似文献

Liebig PS 《Journal of aging & social policy》1992,4(1-2):17-33
Shifts in the American political landscape during the 1980s had impacts on aging policy and on the behavior of aging interest groups through that decade. But perhaps even more important are the likely effects of those changes on aging policy and on the roles of age-related groups in the 1990s--and probably beyond. First, some of the major policy trends of the 1980s are sketched out, especially the renewed emphasis on federalism. Then, an assessment of their effects on aging policy and aging interest groups is provided. Next, a rationale for focusing on state-level policy and a discussion of current aging interest-group mobilization at the state level are presented. Last, the prospects for aging interest-group influence in the 1990s--a period in which the prior decade's emphasis on dual federalism is likely to continue--is addressed. 相似文献

Garry J. Smith Ph.D. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1992,8(4):331-349
A paradox currently exists regarding legal sports gambling in North America: various forms are flourishing in Nevada, Oregon, and several Canadian provinces, while at the same time the United States Congress is conducting hearings on two bills that would prohibit any new state-sponsored sports gambling initiatives. This study examines the issue of why some jurisdictions are enthusiastic about legal sports gambling while others strongly resist the concept. In reviewing these divergent viewpoints, a case study of the newfledged Canadian Sport Select gambling format is presented. This example is used to highly the perils and payoffs of a typical state-sponsored sports gambling scheme, with a view toward broadening our understanding of how they work and how they might be fairer to the public. 相似文献

United Nations. Economic Commission for Africa 《International migration (Geneva, Switzerland)》1986,24(1):197-212
A very large number of skilled Africans are found to be operating in the developed industrialized countries of the West at a time when their national economies are crying out for their services. Ways must be found to return as many of these skilled Africans as possible to the African economy. This out-migration or brain drain has a number of causes, including: 1) real incomes in Africa have been on the decline in the past several years while prices were constantly rising. Professional and salaried workers seek employment in other countries that pay much higher salaries. 2) Promotion on criteria other than merit is common in Africa and diligence and high productivity are not often rewarded. 3) Political interference frustrates public services professionals; they are rendered unable to use their professional judgement in making decisions that affect the economic and social fabric. 4) The inadequacy of higher education facilities and opportunities in African countries encourages the brightest and best qualified Africans to go to Western Europe and North America for school; they tend not to return after graduation. 5) Political upheavals and general instability contribute to feelings of individual insecurity, sending Africans to seek sanctuary in more politically stable and less repressive environments. Actions needed to control this out-migration include: 1) incentive systems should be reviewed with a view to providing realistic levels of renumeration and working conditions should be made to promote job satisfaction and self-actualization. 2) Capacities and capabilities should be strengthened so as to ensure that production of goods and services becomes indigenized and that the development and operation of institutions emanates from within the continent. 3) Educational services should be expanded and improved to obviate the need for large numbers of Africans to seek educational opportunities abroad. 相似文献

Carolyn Saari Ph.D. 《Child and Adolescent Social Work Journal》1986,3(1):15-25
The ability to utilize metaphor is presented as the normal stage in the development of the capacity to symbolize that is characteristic of the young adolescent. Symbolization is considered to be the basic structure through which the individual constructs a knowledge of the reality and of the self. Therefore, staying within the framework of the metaphor in treatment with the young adolescent is beginning where the client is but equally as importantly it is assisting the youngster to further develop both his symbolic capacities and himself. A case illustration is utilized to demonstrate both healthy and pathological usage of metaphorical language. 相似文献

Research on the traditionalist movement against abortion needs alignment with currents in historical sociology, the theory of social movements and the sociology of politics. The religious (specifically, Christian) basis of the right-to-life movement has attracted considerable attention in the literature. The movement is seen as a traditionalist bloc claiming to oppose secularization and return to customary restrictions. However the tradition in question appears to be a recent social construction. There is slim warrant in the actual traditions of Western religion for asserting a categorical right to life. As a result, the movement's ideology is best approached as the product of—rather than the antidote to—secularizing processes (including the demographic transition, discourse about rights, markets for symbolic entrepreneurs and the separation of church and state) and possibly as an unintended import from non-Western religion. Implications for traditionalism, the functions of religion, and the study of countermovements are explored. This case illustrates the value of attending to historical sequences and the external cultural environments of social movements. 相似文献
