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

Blue Shield plans often are granted regulatory advantages by the states in which they operate. Run efficiently, such not-for-profit firms should use these lower costs to eliminate their less advantaged rivals, the commercial insurers. However, these higher-cost commercial providers have been able to offer insurance coverage at prices competitive with the Blues, as evidenced by the fact that Blue plans have, on average, less than 50 percent market share. Similar prices with lower overall costs implies that economic rents are being earned, rents which a not-for-profit firm cannot distribute to owners. In this paper we argue that when there are competing goals among the groups controlling the Blue Shield plans, the different possible "uses" of the regulatory advantage become endogenously determined, necessitating the use of simultaneous equation estimation. Testing this model we find the major effect of doctor-control of Blue Shield plans is to raise doctors' fees while lowering the amount of rents captured by both consumers and administrators.  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

A high population growth rate in the Middle East is prompting investigators to look for cultural conditions and attitudes that can be encouraged to facilitate lower fertility rates. Population researchers find an inverse relationship between the educational level of females and their fertility, especially in Third World countries. This suggests that education can become an internal cultural mechanism for population control. The author explores this notion using data collected from interviews with 750 teenage girls and their mothers in Cairo, Egypt.  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
