Because of cultural, historical and other social structural factors, men and women with the same chronological age have had quite different career trajectories. This paper examines how the different career-paths of men and women academics create differences in their images of aging, self and work. In-depth interviews (N=47) were conducted with a sample of male and female professors, currently between fifty and sixty years of age. Male respondents nearly uniformly followed continuous, linear careers while the women's careers were, with equal uniformity, discontinuous. Data suggest that this difference in career routes fashions different gender timeclocks, i.e., different experiences of aging.  相似文献

This study is a further analysis of the approach taken by Yew-Kwang Ng to derive the utilitarian criterion. Specific for the model is that individual preferences are finitely sensible. In this framweork an analysis of the consequences on social preferences when different kinds of value premises are imposed is made. It is found that the utilitarian criterion is the unique consequence only for very special choices of the value premise. In addition, uniqueness requires the underlying preferences be cardinal. It is also found that finite sensibility induces approximate cardinalization of preferences.I am grateful to Y.-K. Ng, two anonymous referees and an editor of this journal for helpful and constructive comments on earlier versions of this paper. The research was financially supported by the Swedish Council for Research in the Humanities and Social Sciences  相似文献

Fifty high school students met in same-sex dyads for the first time over a cup of coffee in an experimental room designed as a comfortable living room. They then responded to a questionnaire designed to measure liking and perceived similarity. The interactions were video-taped. Two different panels of 6 judges later either viewed (video only) or heard (audio-only) the videotape and raed the subjects behavior on a number of scales. The judges also judged the degree of liking felt by the subjects by estimating subjects responses to the questionnaire. In addition gaze behaviour during the interaction was measured. Factor analysis demonstrated that 60% of the variance in The Liking Scale was attributed to 14 items relating to liking and perceived similarity. A separate factor to assess perceived similarity could not be found. Twenty-nine percent of the variance in the liking reported by subjects was predicted by an interrelated pattern of expressing behaviour including approproate looking, mutual gaze, self-disclosure, synchrony in movement and gesture, expressiveness of the face and liveliness of the voice. Video judges liking correlated 0.33 with subjects liking and 48% of the variance in their judgements was explained by the valid cues of looking and expressiveness of the face. Audio judges liking, although it correlated at 0.34 with video judges liking, did not correlate at all with subjects' liking because of an over-reliance on the important content cues. It is suggested that major problems leading to decoding inaccuracy may be over-reliance on content cues and over-confidence in the possibility of decoding accuracy. The evidence suggests that differences between subjects in encoding may be considerable.  相似文献

Attitudes toward the Equal Rights Amendment were not an importantfactor in the emergence of the "gender gap" in the 1980 presidentialelection. Conclusions to the contrary by news analysts, feministpolitical activists, and political scientists are based on acombination of the power of expectation, faulty analysis, andrandom bias in the most frequently used survey in politicalscience. The data analyzed herein were collected by the New York Timesand CBS News and processed by the New York Times and CBS Newsunder a grant from the Russell Sage Foundation; by Warren E.Miller and the National Election Studies of the Center for PoliticalStudies at the University of Michigan; and by the National OpinionResearch Center of the University of Chicago. The data wereprovided through the Interuniversity Consortium for Politicaland Social Research of the University of Michigan. The New YorkTimes, CBS News, the CPS, NORC, and the ICPSR bear no responsibilityfor the analysis and interpretations presented here.  相似文献

This study compared gay men in monogamous ("closed") relationships (n = 98) and gay men in nonmonogamous ("open") relationships (n = 34). Partners in open relationships were living together significantly longer than partners in closed relationships. Partners in the two types of relationships did not differ in Psychological Adjustment. Controlling for length of time living together, partners in closed relationships reported higher Affiliation/Dependency, more Favorable Attitudes toward the Relationship, and lower Tension than partners in open relationships. Global relationship quality for both types of couples was related to many Attractions, many Barriers, and few Alternatives to the relationship; few beliefs regarding both Disagreement is Destructive and Partners Cannot Change; high Dyadic Attachment; high Shared Decision Making; and low Psychological Maladjustment. Partners in both types of relationships were more similar to each other than different from each other, especially on the variables of Relationship Quality, a belief in Partner Changeability, and Dyadic Attachment.  相似文献

Both published results from the 1930, 1947, 1960 and 1971 censuses and unpublished ones are used to examine the influence that religious denomination, socio-economic group and region exerted on the fertility of marriages contracted between 1876 and 1959. A theory formulated by Lesthaeghe and Wilson on the relation between modes of production and secularization and the pace of fertility decline in Western Europe offers — in combination with van Heek's views on the special position of Dutch Roman Catholicism — a starting point for an explanation of why the fertility decline of Roman Catholics, self-employed and agricultural labourers lagged behind.  相似文献

Individual behavior under risk and under uncertainty: An experimental study   总被引:1,自引:1,他引:0  
These experiments are concerned with individual behavior under risk and under uncertainty. By exploiting the isolation effect the experiments were able to offer to 134 subjects the possibility of actually gaining or losing an important sum of money.The experimental data show that under risk as well as under complete ignorance the subjects' attitudes towards prospects of gains and towards prospects of losses are totally unrelated.The data also show that when facing prospects of gains, the subjects generally take the exact probabilities of the events into account, whereas, when facing prospects of losses many of then have only recourse to coarser categories of plausibility, or even no longer use their information at all.  相似文献

Nigeria, the largest country in Western Africa, has been attracting migrants from neighboring countries for the past decade or so. Although most of the movement of African migrants has occurred outside the regulatory framework set up to control migration, it is important to know the main elements of the latter to understand the likely limitations of the data collection systems currently in operation. Sources of data on international migration include censuses, arrival and departure statistics, work and resident permits, and sample surveys. The author concludes that, with the exception of information on residence and work permits, the relationship between Nigeria's data sources and the laws regulating migration is weak. Arrival and departure statistics, in particular, are not designed to distinguish migrants from all other international travellers. Lacking the political will to modify the system in accordance with internationally accepted recommendations, the prospects for increasing the usefulness of available data are grim.  相似文献

During the past decade, the international statistical community has made several efforts to develop standards for the definition, collection and publication of statistics on international migration. This article surveys the history of official initiatives to standardize international migration statistics by reviewing the recommendations of the International Statistical Institute, International Labor Organization, and the UN, and reports a recently proposed agenda for moving toward comparability among national statistical systems. Heightening awareness of the benefits of exchange and creating motivation to implement international standards requires a 3-pronged effort from the international statistical community. 1st, it is essential to continue discussion about the significance of improvement, specifically standardization, of international migration statistics. The move from theory to practice in this area requires ongoing focus by migration statisticians so that conformity to international standards itself becomes a criterion by which national statistical practices are examined and assessed. 2nd, the countries should be provided with technical documentation to support and facilitate the implementation of the recommended statistical systems. Documentation should be developed with an understanding that conformity to international standards for migration and travel statistics must be achieved within existing national statistical programs. 3rd, the call for statistical research in this area requires more efforts by the community of migration statisticians, beginning with the mobilization of bilateral and multilateral resources to undertake the preceding list of activities.  相似文献

EXPERIMENTS WITH THE MIDDLE RESPONSE ALTERNATIVE IN SURVEY QUESTIONS   总被引:1,自引:0,他引:1  
A series of experiments shows (1) that people are significantlymore likely to select the middle response alternative on anissue when it is explicitly offered to them as part of the questionthan when it is omitted; (2) that merely mentioning that thereis a middle alternative, in the preface to the question, makesit more likely that respondents will select it, even thoughit is not offered to them as an explicit choice; (3) that theorder in which the middle alternative is presented in the question—inthe middle or last position—can make a significant differencein the results, but that a "recency bias" does not occur invariably,or consistently; and (4) that people who select a middle responsealternative when it is offered would not necessarily answerthe question in the same way as other respondents if forcedto choose sides on the issue.  相似文献
