The biotechnical "revolution" has fast come upon us. It promises to produce both substantial benefits and difficult dilemmas for individuals and society. Despite the growing attention being paid to biotechnology, a major unanswered question is who shall control the development and use of the powerful array of human genetic and reproductive innovations. Should the decisions be left to individual consumers and private industry or should they be made by the government or other social institutions? After briefly reviewing development in human genetics and reproduction and describing trends toward commercialization of them, this article discusses the dilemmas these trends raise for a democratic society. It argues for the urgent need to delineate societal goals and priorities for the future and for technology assessment as early as possible in the developmental process. The article concludes by presenting some examples of the social policy problems now emerging.  相似文献

"The Soviet Union is experiencing a substantial reduction in the growth of its working-age population, accompanied by a shift in the distributional pattern of population growth, with the largest increases occurring in regions where geographical mobility is low. After describing the types and scales of manpower migration in the USSR, the [authors discuss] the means used to encourage workers to move to the sparsely populated developing regions and away from large cities. This is achieved primarily through incentives, with wage differentials decreasing in importance compared with incentives bearing on the quality of life; restrictive measures have a purely corrective function."  相似文献

Summary Marital status life tables, which follow a real or synthetic birth cohort through life and the marital statuses of 'never married', 'presently married', 'widowed', and 'divorced', reflect observed marriage, divorce and mortality behaviour and provide a detailed record of a cohort's experience. The present paper analyses such tables for cohorts of men and women born in England and Wales between 1900 and 1945. The results show that the later cohorts deviate substantially from the 'European pattern' of late marriage and high proportions never marrying, and that a dramatic rise in divorce has taken place, so that among the later cohorts one marriage out of four ends in divorce.  相似文献

The client oriented cost outcome system has been under development in Pennsylvania community and hospital programs since 1972. The system builds upon the behavioral and decision data generated with or on behalf of consumers. Flexibility for local program system design is permitted if the procedures of consumer intake, review, and termination document each consumer's (a) problems, resources, and goals, (b) overall functioning level in their ordinary community, and (c) services intended and rendered as related to (a), above. While the system's primary application is in providing feedback for local program quality assurance and evaluation procedures, aggregation of data permits program planning and evaluation at county, state, and federal levels in terms of (a) client demographic or diagnostic characteristics, and (b) program service characteristics and objectives.  相似文献
