This paper reviews changes in homogamy by migration status and educational level in Monterrey, Mexico, through the analysis of marriage patterns for two cohorts of men born in 1905–1934 and 1940–1969. Results show a significant increase in educational homogamy, as well as in homogamy by rural origins. The changes suggest that education has played an increasingly important role in the process of mate selection, although certain particularistic characteristics, such as being a rural immigrant, are still important in marriage formation. The paper concludes with a discussion of the implications of these findings for the relationship between homogamy and social stratification.

Whereas period life expectancy constitutes an intuitive indicator of the survival conditions prevailing at a particular period, this paper argues that, given the existence of welfare interdependencies, that widespread indicator is nonetheless an incomplete measure of the longevity achievements relevant for human well-being. The central importance of coexistence for human-beings implies that usual life expectancy measures should be complemented by joint life expectancy indicators, which measure the average coexistence time under particular survival conditions. After a study of the theoretical foundations of ‘single’ and ‘joint’ life expectancy indicators, it is shown that joint life expectancy measures tend to enrich significantly the comparison of longevity achievements across countries and periods. Moreover, the introduction of joint life expectancy indicators—as a complement to conventional life expectancy measures—into multi-variable indexes such as the United Nations’ HDI is also shown to affect international rankings of standards of living to a non negligible extent.

The 1994–2000 waves of the European Community Household Panel are used to study the earnings of immigrants as compared to native workers in 15 European countries. At the time of arrival, there is a significant negative partial effect of foreign birth on individual earnings compared to the native born in the destination of around 40%. These differences vary across origins and destinations and by gender. Immigrant earnings catch-up to those of the native born after around 18 years in the destination. Schooling matters more for earnings for women, whereas, language skills are relatively more important for men.

Black is not always black. Subtle distinctions in skin tone translate into significant differences in outcomes. Data on more than 15,000 households interviewed during the 1860 US federal census exhibit sharp differences in wealth holdings between white, mulatto, and black households in the urban South. We document these differences, investigate relationships between wealth and recorded household characteristics, and decompose the wealth gaps to examine the returns to racial characteristics. The analysis reveals a distinct racial hierarchy. Black wealth was only 20% of white wealth, but mulattoes held nearly 50% of whites’ wealth. This advantage is consistent with colourism, the favouritism shown to those of lighter complexion.

Research suggests that victims of bullying may lack skills in emotional regulation, a process which facilitates coping with provocative situations to lessen the stress of negative emotions (Cicchetti, Ackerman, & Izard, 1995). The present study examined the emotional regulation and display patterns of victims during classroom bullying episodes. Children in grades one through six were observed during free play in the winter and spring of three consecutive school years. Results of the study indicated that the coping styles observed in victims of bullying can be grouped into two distinct clusters: 1) problem-solving strategies that are associated with the de-escalation and resolution of bullying episodes; and 2) aggressive strategies that tend to perpetuate and escalate the bullying interaction. Parallels were found between victims' and bullies' emotional displays. Results are discussed in the context of how maladaptive emotional regulation processes may act as risk factors for chronic victimization.  相似文献

Emotion Regulation in Low-income Preschoolers   总被引:2,自引:0,他引:2  
The present study was concerned with identifying the causes of low-income preschoolers' negative emotions and their most common regulation responses. The relations of family socialization practices and temperament to the children's emotion regulation skills were also examined. Ninety predominantly minority low-income preschoolers (46 boys) and their mothers participated. During visits to the children's preschools, observers watched for expressions of anger and sadness, and recorded the causes of the displays and the children's reactions. Mothers reported on their emotion socialization and discipline practices and their children's temperament. Although the children expressed more anger than sadness, they used more constructive reactions in response to sadness and more non-constructive reactions in response to anger. Maternal reports of appropriate family emotion were associated with low levels of non-constructive regulation responses to anger and sadness whereas reports of inconsistent parental discipline were generally associated with non-constructive regulation responses. All in all, the findings of this study are in accord with findings on middle-income children and indicate that low- and middle-income children are more alike than different with regard to the regulation of negative emotion in the peer environment.  相似文献

Human services organizations in the United States are currently faced with the problems of a diminishing and shifting resource base coupled with increasing demands for services. In addition, national demographic changes with increasing social diversity, and a rise in racial, ethnic, gender and other group-based tensions have posed special challenges for human service organizations. By tracing the history of social work approaches to working with ethnic minorities, this paper argues that responses to environmental flux have in fact been inadequate in addressing issues of social inequalities and injustices. We articulate a vision of socially just and diverse human services organizations that are both empowering and empowered. We call these Multicultural Human Services Organizations (MHSO). We spell out praxis and research agendas that continue the social justice-social diversity mission that is central to our vision.  相似文献

In this paper we investigate the asymptotic critical value behaviour of certain multiple decision procedures as e.g. simultaneous confidence intervals and simultaneous as well as stepwise multiple test procedures. Supposing that n hypotheses or parameters of interest are under consideration we investigate the critical value behaviour when n increases. More specifically, we answer e.g. the question by which amount the lengths of confidence intervals increase when an additional parameter is added to the statistical analysis. Furthermore, critical values of different multiple decision procedures as for instance step-down and step-up procedures will be compared. Some general theoretic results are derived and applied for various distributions.  相似文献

In this study we explored if the psychological and social resources of aged people (over 75 years) in Finland predict their subjective well-being and experienced state of health (n = 348). Data were taken from a larger Finnish survey on living conditions. Based on previous research on younger people we formed a model where morbidity, experienced quality of social support and sense of coherence together with economic resources are the predictors of both experienced state of health and subjective well-being. LISREL (8) path analysis was used to test the model. The model providing the most parsimonious explanation of the data suggested that a strong sense of coherence and high experienced quality of social relationships are strongly related to subjective well-being. Experienced state of health was associated with morbidity and subjective well-being, but there was no significant relationship between subjective well-being and morbidity.  相似文献
