"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

"This article examines the 1980 earnings and earnings attainment process of Afro-Caribbean immigrants [to the United States] relative to Afro-Americans, native-born whites and foreign-born whites. Controlling for gender, the comparisons consider Caribbean Islanders as a whole and disaggregated by nation of origin. The results indicate that, in 1980 at least, fact did not justify the opinion that any West Indian subgroup had higher gross or net earnings than native-born blacks. Rather, a few non-English speaking subgroups fared worse. In addition, regardless of national background, Caribbean-born men experienced vast earnings disparities relative to white men. This was not the case for West Indian women, whose net earnings were, at minimum, equivalent to those of white women. Further analysis suggests that, for most Caribbean groups, West Indian background adds little to an understanding of the earnings attainment process that cannot be obtained from other measurable characteristics." 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

The author describes the use of a model to investigate "the age composition of the stationary population resulting from a condition of below replacement fertility and a continuous stream of immigrants, the size of which for any age remain invariant over time.... We have shown that the number dying among [migrants] is the same as the number of them entering over any time interval, and that is precisely how their stationarity is maintained." The geographical focus is on developed countries that are experiencing below-replacement fertility levels. (SUMMARY IN FRE AND SPA) 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

"This paper proposes a conceptual framework for analyzing migration as a household event and presents two public use microdata applications of this approach for out-migrants from New York City. The distribution of single- and multi-origin households by race and Hispanic origin permits a more rigorous analysis of household migration differentials....and the disaggregation of household members by migration status provides insight into the household outcomes of the migration process...."

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

Conclusion Like many studies of covert deviance, this paper is based upon a captive sample of persons who have come to the attention of law enforcement agencies. The existence of Laud Humphreys' research, however, makes possible a comparison of police generated data with data obtained through observations and interviews with unapprehended offenders. Because police observations were so detailed, a rare opportunity to replicate a qualitative study presented itself. This research largely substantiates the picture drawn by Humphreys in his classic study,Tearoom Trade: Impersonal Sex in Public Places. Consistent with his observations, most tearoom participants (a) communicate through non-verbal gestures and seldom speak, (b) do not associate outside the tearoom or attempt to learn one another's identity or exchange biographical information, (c) do not use force or coercion or attempt to involve youths or children, (d) are primarily heterosexual and married, (e) depart separately with the insertor leaving first, (f) commit their sex acts out of sight of the entrance and accidental exposure, (g) do not undress or engage in anal sex, (h) break off sexual contact when someone enters the washroom, (i) rarely approach straight men, (j) read and write sexually explicit homosexual graffiti, and (k) linger inside and outside the washroom for someone to appear. In addition, (1) fellatio is generally not reciprocated and fellators are usually older men; (m) most offenders are neat in appearance; (n) some engage in series and simultaneous encounters; (o) encounters are brief, usually not exceeding twenty minutes; and (p) few have criminal records with the exception of those previously convicted of similar offenses.The behavior of players reveals remarkable consistency over time, from community to community, and across national boundaries. Many men, the majority of them married and primarily heterosexual, continue to visit out-of-the-way public washrooms in search of fast, impersonal, and exciting sex despite the risk to family, friends, job, and reputation. Although shopping malls have usurped public parks as the favorite locale of tearoom participants, the basic rules of the game and profile of the players—as Humphreys contends—remain the same over time and place. 相似文献

Bingo is one of the most popular and most accepted forms of gambling in the United States today. Yet, despite its popularity, many bingo players are not completely comfortable with the moral rightness of their actions. This participant observation and interview study spanning a 5 year period shows how bingo players use superstitious strategies, such as feelings, hunches and psi, attitudes, and luck to neutralize their marginally deviant behaviors. 相似文献
