Rao V 《Journal of population economics》1988,1(3):225-233
"There are numerous reasons why mortality and life expectancy vary between countries. Epidemiological studies seem to indicate that dietary variations may be among them. A sample of 51 countries studied with data from the International Comparisons Project and other sources, shows that after controlling for nutrient intake, consumption of medical goods and services, income distribution, weather, and literacy, countries with more meat and poultry in their diet have lower life expectancies after age five. The results for infant mortality and child death between one and five indicate that a more animal-intensive diet may be actually beneficial, especially if fish consumption is increased and meat and poultry consumption reduced." 相似文献

Tabone V 《Bold : quarterly journal of the International Institute on Aging (United Nations - Malta)》1992,3(1):9-10
This is the keynote address of H.E.Dr. Vincent Tabone, President of Malta, at the International Conference on Aging, which was held in San Diego in September 1992. He states that the conference celebrates the tenth anniversary of the Vienna International Plan of Action, and provides an opportunity to evaluate progress and plan future direction. Dr. Tabone, as Minister of Foreign Affairs, first introduced the question of aging at the UN General Assembly over twenty years ago; the United Nations Secretariat established its first program in the field of aging in 1970. At the World Assembly on Aging in 1982, all members adopted the International Plan of Action, which defined guidelines for policies and programs in support of the aging populations. As a direct result of this, and in support of the needs of developing countries, the UN signed an agreement with the government of Malta that established the International Institute on Aging as an autonomous body under the auspices of the UN; it is the major expression of the Vienna Plan of Action. Concern for aging populations has developed enough maturity and momentum to oversee its own progress. Although current events may relegate the social and economic implications of the aged to the sphere of rhetoric, they demand thinking in terms of generations and transcend all political boundaries. This conference will evaluate progress toward deflecting a situation where the elderly constitute an increasing proportion of the population, without adequate and appropriate provision for their livelihood, and could have direct bearing on encouraging and ensuring the continuity of the family's vital and traditional role in preserving the dignity, status, and well-being of its aging members. A nation which begrudges its dues to the elderly, the successful products of society and triumphs of life, denies its past. This conference is a reaffirmation of commitment to the United Nations Principles for Older Persons, an omen of the review of the Global Targets on Aging for the year 2001 by the General Assembly at its forty-seventh session in October, and a stepping stone in the path toward integrating the elderly more fully into the mainstream of society. The year 1992 is a year for solidarity between the generations. 相似文献

"This study compares the fertility patterns of foreign-born and native-born women in Canada and examines whether [the] same set of social characteristics accounts for differential fertility among both the groups. The study also assesses the importance of social characteristics and assimilation on immigrant fertility behavior. Two generations of currently married/cohabiting women with spouse present are analyzed using multiple regressions. The results reveal similar effects on fertility of social characteristics for foreign-born and native-born, while in the case of younger generations the effects are stronger." 相似文献

Bodrova V 《Vestnik statistiki (Moscow, Russia : 1949)》1992,(3):13-17
These are the results of a 1971 survey on reproductive behavior in the former Soviet Union. The survey covered 3,152 women aged 16 or over living in rural or urban areas. Questions were included on ideal, desired, and expected number of children. The results indicate that low fertility expectations characterize the majority of the population and that current political and economic problems are likely to push expected fertility even lower. Significant differences between rural and urban populations and among regions are identified. 相似文献

The China Population information Centre (CPIC), set up in May 1980, is a national institution for population information research under the State Family Planning Commission. Its main functions are to 1) collect, process, and distribute and foreign materials on population and family planning; 2) collect, tabulate, and analyze population and family planning data; 3) keep abreast of new population and family planning developments within and outside the country; 4) edit and publish information materials; and 5) provide information users with diversified services. The CPIC has 8 operational units: 1) the Library, 2) the Statistics Division, 3) the 1st Information Research Division, 4) the 2nd Information Research Division, 5) the Editorial Division, 6) the Translation Division, 7) the Computer Division, and 8) the Technical Support Division. 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

"Complete decennial censuses are needed for small areas and other domains. Sample surveys yield diverse and timely data. Censuses can also be combined with samples, and sometimes with data from registers, for diverse estimates that are detailed over both space and time, and hence are timely for small domains. Methods of 'postcensal estimates' for small domains are described. We note uses of censuses for improving samples and of samples for improving censuses, and propose a method for cumulating data from 'rolling' (or rotating) periodic (weekly, monthly or quarterly) samples specifically designed to cover the population in detail over designed spans (annual and quinquennial)." 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
