V.P. Kultygin 《International Journal of Social Welfare》1993,2(3):142-149
The article describes the socioeconomic situation of the Russian population and its dynamics in 1992. The analysis is based on series of regional sociological surveys led by the All-Russian Living Standards Research Center and on official Russian statistical data. The basic unit of analysis is the family, and hence family typology approbated both in research and in practical social work is introduced. Besides describing and discussing the growing poverty tendencies in contemporary Russia, the article also contains methodological recommendations for social policy bodies and social workers on the strategy of work in social maintenance and social support of the least secure population strata. 相似文献

1. With the consistent number of part-time nurses in the workforce, hospitals would benefit by more actively integrating them into professional nursing practice. 2. Empowering part-time nurses by affording them the opportunity to provide primary care has the potential to effectively use part-time personnel, decrease the workload for full-time staff, offer more flexibility in scheduling, and result in savings for hospitals in terms of nursing recruitment and retention. 3. This program has successfully developed and implemented a model of primary nursing that places three part-time nurses on a team capable of handling two to three primary patients. The success of this model has been attributed to excellent communication, trust in one another's professional skills, and nursing expertise. 相似文献

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions. 相似文献

"In the first half of the article, a broad account of content and procedures is given. In conduct of individual surveys, the achievements of the World Fertility Survey were based on thoroughness rather than technical superiority. The later aspects of the program, including analysis, archiving, and data dissemination, were more innovative and represent models of excellence for similar future enquiries. In overall terms, the program is judged to be an expensive success. In the second half of the article, two methodological issues are discussed in more detail: the collection of retrospective birth histories and the translation of survey instruments into local languages." Comments by Anthony G. Turner (pp. 768-9), Kweku T. de Graft-Johnson (pp. 769-70), Burton Singer (pp. 771-2), and Joel E. Cohen (pp. 772-4) are appended. 相似文献

"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

"This article reports findings that have emerged from an effort made at statistically measuring the effects of immigration on the earnings of U.S.-born youth. The presence of immigrants arriving before 1965 has a positive impact on youth earnings. Recently arrived immigrants impact negatively, however. These results are consistent with recent findings that the skill level of immigrants arriving within the last two decades is lower relative to that of immigrants arriving earlier. The results also show that the negative effects diminish as the youth ages, reflecting skill acquisition and job mobility of the young worker into jobs less vulnerable to competition from immigrant workers." 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

Until recently, nothing much beyond education and the dispensing of condoms was being done to control the spread of AIDS. We have not yet taken sufficient measures to prevent the spread of this disease. Instead, we insist on protecting the privacy of the HIV-positive individual. However, we ignore the right to privacy by mandating testing for syphilis, which is not nearly as serious a disease as AIDS. Now, mandatory testing of health care workers is being proposed more frequently. 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
