Holstein M 《Journal of aging & social policy》1992,4(3-4):17-34
This essay offers a feminist perspective on the call for a "productive aging" society, and says that the movement provides an answer before we have systematically asked questions about the meaning of old age. An emphasis on productivity, among other things, can devalue relational activities, often inherent in women's roles, and certain older people-older women in particular. The author proposes a number of measures for the short term, so that society can be responsible to older women who need and want jobs, as well as ideas for more far-reaching change. 相似文献

Since the aging of populations, with its extensive consequences, requires ample planning, demography is the soothsayer of gerontology. The realization that aging is the main demographic event of this century has generated an interdependence among demography, gerontology, and geriatrics, and created a base from which to extrapolate socio-political consequences from population changes. Demography transforms the personal unidimensional experience of aging to a dynamic one which traverses time and geography. Chronological age is not an exclusive criterion; this presents an opportunity to explore avenues grounded in the realms of economics, politics, policy, and culture. The inclusion of demography in international training courses of the International Institute on Aging (United Nations-Malta) has made possible an easier progression toward discussing policy, planning, funding, and social services within a broader context. The dependency of aging upon demography established the collaborative development between the Committee for International Cooperation in National Research in Demography (CICRED) and INIA and the joint hosting of a synthesis meeting on Population Ageing Research Project. In this collection of papers, Don Rowland creates the concept of the Gerontological Transition which interprets aging as a process of cohort flow; Raul Hernandez, through an evaluation of regional data, provides a classic analysis of changing age ratios within the population as a whole; Anthony Warnes, through use of mortality rates, provides a demographic analysis to expose the age-dependent variability in health and welfare payments; Paul Paillat transposes demographic numbers into social consequences; Miroslav Macura focuses on the youth in these population shifts; and the emerging elderly in the never ending cycle of events are viewed. Planning beyond the individual lifetime will become a necessity for mankind. 相似文献

The paper shows that (a) the age difference between spouses can be and has been different for men and women; (b) male and female age differences can exhibit different trends; (c) the discrepancy is due to remarriage; (d) the age difference fluctuates substantially through time; (e) trends in the age difference are not readily interpretable as reflecting change in the relative status of the sexes; and (f) that trends in the age difference may be linked to marriage market conditions. The paper argues that marriage and fertility data for both men and women are increasingly necessary because of rises in marital breakdown and the associated divergence of the experience of men and women.Cet article montre que (a) les différences d'âge entre époux peuvent être et ont été dissemblables pour les hommes et les femmes; (b) les différences d'âge masculines et féminines peuvent présenter des tendances différentes; (c) la divergence est due aux remariages; (d) les différences d'âge varient de façon importante au cours du temps; (e) les tendances dans les différences d'âge ne sont pas simplement interprétables en termes de changements dans le statut relatif des sexes; et (f) les tendances dans les différences d'âge peuvent être reliées aux conditions du marché matrimonial. L'article montre que les données sur le mariage et la fécondité à la fois des hommes et des femmes, sont de plus en plus nécessaires du fait de l'accroissement des ruptures d'unions et de la divergence des expériences masculines et féminines, qui lui est associée.

Social workers are required to collect a considerable amount of personal information about clients and their families which may be unrelated to direct clinical work. Administrators often use this for the purpose of payment, service documentation, agency planning, and accountability. The worker's concern about the appropriateness of collecting this data may result in poor compliance or even falsification of information. In a survey of Minnesota social workers, noncompliance with data collection requirements was substantial. The authors also found a significant degree of conflict about privacy and confidentiality issues. These findings suggest a basis of concern for those who must rely on accurate data for administrative planning. 相似文献

The author argues that the burden of proof for the safety and efficacy of some medical devices properly lies with the manufacturers of the devices and with the providers who use them. The controversy over breast implants is used as a case for this shift in the burden of proof of safety and effectiveness. 相似文献

This article is the second part in a two-part series on how to work with an executive search firm. The first article, which appeared in the September-October 1992 issue of Physician Executive, focused on executive search from the candidate's perspective. This article focuses on how organizations can work with an executive search firm to recruit and retain top management talent. 相似文献

At conferences of physician managers, the issue almost always arises of whether or not a physician manager needs to obtain a formal management degree. There is no clear answer to such a question, reason enough for its perennial appearance at such meetings. These decisions are the result of both personal and environmental factors, each creating unique situations that will dictate the direction taken. In this article, one such direction is described. 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

Pharmaceuticals traditionally have been viewed as a cost-effective component in medicine's technological armamentarium. The use of pharmaceuticals has been estimated to account for 6-8 percent of the nation's total expenditures on health care. The first wave of pharmaceuticals/biologicals that has been produced by the biotechnology industry has offered therapies that can provide much benefit to patients, but it has also raised concern about the cost of these new recombinant drugs. In addition to pricing, methods of promotion and modifications in the FDA approval process have raised concerns. 相似文献

College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press. 相似文献
