"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

Public policy decisions in health are increasingly difficult and expensive. Although there will never be enough information available, private foundations can help to bridge the most important gaps in knowledge. Larger foundations may also wish to respond to those who doubt the value of foundation activities. This article reviews the experiences over the past eight years of The Robert Wood Johnson Foundation in employing evaluation and related social research procedures in the planning and implementation of a major philanthropic effort to improve the health and medical care of Americans. Discussed are the still evolving Foundation evaluation framework, the unanticipated problems in undertaking specific evaluations, and the substantive findings of some of the studies.  相似文献

The 2nd Chinese Scientific Symposium on Theories of Population was held in Chengdu, Sichuan, on December 7-13, 1979. The symposium was jointly sponsored by the Department of Family Planning of the Chinese Central Government, Chinese Academy of Sociology, Sichuan Provincial Revolutionary Committee (SPRC), and the Institute of Population Theories of the Chinese People's University (IPT). There were 255 attendants, representing 60 academic institutions, 14 scientific research organizations and 31 provincial, municipal, and autonomous regional departments of family planning. The main theme of the meeting was "Population Problems and Their Solutions Facing the Four Modernizations in China." 147 papers were read at the meeting. The meeting opened with a welcoming speech by Comrade Liu Haiquan, Vice-Chairman of SPRC, who pointed out the challenge Chinese family planners would face in advocating the 1 child family policy. Long speeches were made by Comrade Chen Dao who stressed the training of workers for Chinese population research and by Comrade Du Xinyuan (secretary of SPRC) who summarized results on recent family planning efforts in Sichuan. During the meeting, based on their contents, the papers were divided into 7 groups for separate discussions: 1) population development in the socialistic society, 2) relationship between population and economic developments and between population control and the 4 modernizations in China, 3) possible population problems in China, their nature, etiology and methods of solution, 4) population policies and family planning in China, 5) trends in population development and population planning in China, 6) problems of population distribution in China, and 7) development of population theories in China during the past 30 years. The meeting discussions were summarized by Comrade Liu Zheng of IPT who noted that there were 84 more attendants and 110 more papers in this meeting than the first held in 1978.  相似文献
