"This paper seeks to (1) identify socioeconomic variables that are expected to generate fertility differentials; (2) hypothesize the direction and magnitude of the effect of each variable by reference to a demand-for-children model; and (3) test empirically the model using evidence from Costa Rica. The estimates are obtained from a ten-percent systematic random sample of all Costa Rican individual-family households. There are 15,924 families in the sample...." The authors specifically seek "to capture the effects of changing relative prices and available income and time constraints on parental preferences for children. Least-squares estimates show statistically significant relationships between household fertility and opportunity cost of time, parental education, occurrence of an extended family, medical care, household sanitation, economic sector of employment, and household stock of nonhuman capital."  相似文献

The economic adaptation of immigrants to Canada is analyzed using government data on the labor force and landed immigrants. In particular, the labor force experience of a sample of immigrants in Canada is examined and compared with that of a Canadian cohort with regard to length of unemployment and income. "Differences in unemployment and insurable earnings are examined by age, sex, immigrant category..., world area of last permanent residence, official language abilities, education, and region of residence."

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

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

A scattering of recent research has studied the current politicalbeliefs and attitudes of individuals identified as "1960s activists."In contrast to much of the treatment accorded such people inthe popular media, this research tends to find most of theseactivists currently liberal on a wide variety of political topics.However, in the absence of panel data, most of this researchhas had to assess any change in the activists' attitudes eitherby assuming the activists' past positions or by trusting totheir retrospective reports. In this paper we report on panel data from a large group ofwhite activists, mostly students, who spent the summer of 1965organizing voter registration drives in Southern black communities.In some specific areas on which the activists tended to holdrather extreme positions in 1965, they may have moderated by1984. However, their overall pattern of response on a wide varietyof issues is basically stable over this twenty-year period.  相似文献

An experiment was designed to examine the role of a person's predispositions toward communication in reactions to violations of proxemic expectations. Working with Burgoon's (1983) violations of nonverbal expectations model, Buller and Burgoon (1986) predicted that predispositions may bias evaluations of initiator reward and violation valence. Apprehensive individuals should unfavorably evaluate the initiator, negatively valence a violation and comply less, while nonapprehensive individuals should favorably evaluate the initiator, positively valence a violation, and comply more. Alternately, this paper proposes that predispositions may affect arousal-induction rather than initiator evaluation and violation valencing. Following Patterson (1983), apprehensives should experience more arousal and comply more to reduce the arousal, whereas nonapprehensives should experience less arousal and comply less. Four initiators engaged 90 subjects in experimental conversations which ended with a request for the subjects' signature on a petition. Initiators either remained at the normative distance, moved one seat closer, or moved one seat farther from the subject. Results showed that apprehensives and subjects experiencing close violations complied more, suggesting that communication apprehension influences arousal-induction. Communication apprehension had no main effect on perceptions of initiator attractiveness and similarity, implying that arousal not perceptions of the initiator is affected by predispositions toward communication. Initiator gender again emerged as an important characteristic which influences a subject's perceptions of initiator reward.  相似文献

The impact of immigration on unemployment in Canada is examined for the period 1983-1985. The authors attempt to construct a balance sheet of immigration in terms of labor supply and demand. They conclude that immigrants create more jobs than they fill, and that their net effect on the employment situation is positive. (SUMMARY IN FRE AND SPA)  相似文献
