Common sense has to do with problem solving. In the complexities of everyday human life, we are faced time and again with the need to solve problems. In fact, every situation we face, at least at the first exposure, requires some form of problem solving. When we want food, we have to solve a series of problems from acquisition to preparation to serving and eating. When we deal with organizational needs, problem solving is the daily fare.  相似文献

Information about board-and-care homes reported in the media and in federal committee hearings indicates that they are shoddy and exploitative environments that do not provide adequate care. Research done in board-and-care homes in recent years, however, demonstrates that they can provide adequate care and a satisfying environment for some of the people they serve. Policy at the federal, state, and local levels should be guided by both the need to assure the health and safety of board-and-care residents and the needs of residents and operators identified in scientific studies.  相似文献

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989   总被引:1,自引:0,他引:1  
All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates.  相似文献

"A human capital framework is utilized to examine the economic progress of nine nationality groups of foreign workers [in Kuwait] using data from the 1983 national Labor Survey. The sources of earnings' variations of particular interest to us included different degrees of education and experience transferability, occupational affiliation and ethnic background. In general, the results derived from the analysis suggest that 1) foreign workers achieve a discernible economic progress as their residence lengthens; 2) the rate of economic progress varies depending on worker's education, home and Kuwait-specific experience, occupational status and ethnic background; and 3) about one third of the earnings inequality is due to unexplained factors including discrimination."  相似文献

Recent trends in the process of stratification   总被引:1,自引:0,他引:1  
Using the 14 annual cross-sections from the General Social Survey, we specify a "basic model" of attainment and describe the year-by-year fluctuations in its parameters. The results are partially consistent with theories describing the gradual growth of universalistic patterns of stratification and mobility. Under a linear model of educational achievement, we find that the direct effects of race are weakening and the returns to class-based advantages are declining in tandem. The contours of the socioeconomic "gender gap" are also changing in important ways, with the male intercept declining at a rapid pace and the female term registering small and insignificant year-by-year gains. At the same time, the returns to experience and schooling are increasing for men, whereas the corresponding returns for women have remained stable over the 15-year period. This pattern of interaction effects implies that the size of the gender gap varies over time and across different population groups.  相似文献

In this paper we attempt to explain the occurrence of population cycles in industrialised economies where the birth rate depends on the difference between the actual and the expected consumption rate. This model of an endogenously growing population brings together Easterlin's idea of an adapting aspiration level with the neoclassical optimal growth paradigm. It is shown that in this highly aggregated demo-economic system (i.e., without inclusion of the age structure of a population) swings both in the economic and demographic variables may exist. The reason behind this strange optimal behaviour is identified to be an intertemporal substitution effect between current and future levels of consumption.We wish to thank A. Novak for helpful assistance and an anonymous referee for useful comments. Financial support by the Austrian Science Foundation under contract No. P6601 is acknowledged.  相似文献

The author discusses three of the six national censuses taken during the ninteenth century in Colombia--those for 1835, 1843, and 1851. The focus is on the importance of macro patterns generated by the data, the methods recommended to overcome the problems of the censuses, and ways to make the information useful for historical demography.  相似文献

This study of a collection of self-observed lies told in everyday interactions indicated that all informants lied; that lying was, generally, an easy and spontaneous activity; and that our varied informants told lies in much the same manner and for the same reasons. The analysis of the general features of the interactions in which lies were embedded showed that many lies are the consequence of a preference system that promotes acceptance and hides rejection in the sequential organization of interaction. The lies found in pre-acceptance and pre-rejection sequences indicate that both parties contrive for acceptance. The negative cases of lies told in rejection of deprecating assessments suggest a broader theoretical template that encompasses the lies told for acceptance as a subset of the interactional preference for social solidarity. In contrast to the view that telling lies undermines social cohesion by interfering with trust, this study indicates that many lies are told to affirm affiliation.  相似文献
