China. State Family Planning Commission. Planning Statistical Department 《China population newsletter》1989,6(1):6-7
The Planning and Statistical Department of the State Family Planning Commission of China in July 1988 implemented a fertility and birth control survey in China on 2.16 million married women ages 15-57 using stratified, systematic, clustered, and non-proportionate sampling. 3 questionnaires were used: household, married women, and sample unit covering basic status, family planning status, general characteristics of pregnancy and contraception, population flow, deaths since 1981, and socioeconomic status. The authors suggest several international cooperative research projects including: design of fertility and contraception survey; Chinese population growth; Chinese population dynamics; dynamics of marital and family status; fertility; contraception and birth control; mortality; migration; status of the nationalities of China; population development; regional fertility status; and others. Data from the survey will be available in June 1989. 相似文献

The concept of spatial demographic order is introduced and defined as the preferred spatial distribution of a given demographic variable. The results of a multivariate statistical analysis of demographic trends in rural and urban areas in Poland are presented to illustrate the convergence of such trends in the areas studied. The author concludes that the increasing similarity in demographic processes between rural and urban areas is due mainly to migration. 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

一、哪些做法不对?社会学确实在许多大学生的心目中威信不高,他们时常认为:社会学令人厌烦地对一些明显的、过分抽象的和对生活用处不大的事理作过分冗长的讨论,是堪与经济学并列的最"乏味"的科学.我们的一些同行认为,产生这种看法的原因是社会学太专业化和科学化了.但我们认为原因远不止此.专业化的知识对于任何寻求更多地了解世界的科学来说,似乎是必不可少的和正当的目标.问题不在于教师对学生教授了什么,而在于哪些还没有传授给 相似文献
