This study examines differential prediction of WIAT achievement scores based on WISC-III FSIQ in white as compared with African American and Hispanic children, and in females as compared with males. A procedure which allows simultaneous comparisons of slopes and intercepts across groups is employed. The results are consistent with previous research findings in supporting the general absence of bias in predicting achievement from IQ.  相似文献

The present paper first presents the attitudes toward suicide and a suicidal classmate among 98 female and 69 male (N = 167) Swedish high school students. Secondly, the Swedish sample was compared with 167 (89 female and 78 male) Turkish high school students from a previous study. Among Swedish students, more males than females said that people have the right to commit suicide and suicide can be a solution to some problems. More females than males expressed a belief in life after death. Swedish adolescents were found to be holding more liberal attitudes toward suicide than Turkish adolescents. However, Turkish adolescents showed greater acceptance for a suicidal peer than Swedish adolescents. The results are discussed in terms of socio-cultural factors and related literature. The need for educational programs to provide basic knowledge about suicide and, effective ways of dealing with and helping suicidal peers is implicated.  相似文献

The literature is reviewed to define a sense of community in the workplace and to identify factors that may foster it. A model is developed and estimated with survey data from a culturally diverse sample of men and women performing lower-level jobs at a medium-sized manufacturing firm. Results of regression analyses are reported that correct for sample selection bias resulting from the lower response rates of minority workers. Findings suggest that well-designed jobs and supportive workplace relationships and policies are important in explaining workers' sense of community, defined as workers' perceptions of mutual commitment between employee and employer. Informal sources of support play a larger role in explaining men's sense of community, while formal sources of support are more important in explaining women's sense of community. Findings further suggest that African American workers, especially women, have a difficult time experiencing a sense of community at work. The authors thank the employees of Fel-Pro for their participation in this study and Melissa Roderick, Michael Sosin, and anonymous reviewers for their thoughtful comments. This research was funded by the Fel-Pro/Mecklenberger Foundation and the Lois and Samuel Silberman Fund.  相似文献

Among the 200,000 immigrants who entered Israel in 1990 were a considerable number of families headed by single mothers. Their most prominent feature was the fact that a three-generation system—a single Soviet mother, her own mother, and a single child—formed the family unit. Rooted in changes occurring in the Soviet family life cycle over the past 70 years, this configuration is uniquely self-contained. This article is an early inquiry into a new family structure that will become part of the social fabric of the multi-ethnic society in Israel. The challenge will be to help in the absorption process by recognizing, encouraging, and facilitating the strengths this type of family brings with it and to plan support networks to substitute for those left behind.A previous version of this article was presented at the Third World Family Therapy Congress, June 2–6, 1991, Jyvaskyla, Finland.  相似文献

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were significant mediators of client satisfaction. The authors thank the National Institute of Mental Health for their financial support (MH43248, MH42357) for this project, Dorothy Gano for word processing and editorial assistance, and Gitry Heydebrand, Melissa Dannelet, Betty Tempelhoff, Ruth Smith, and Laeeq Ahmad for assisting in the interviews of clients. We are also appreciative of the cooperation given to us by the staffs of Malcolm Bliss Mental Health Center, St. Patrick's Center, the Community Advocacy and Support Alliance Program, and the St. Louisemergency shelters. Finally, we thank all of the participants in this study; we hope that their homelessness has now ended.

A questionnaire assessing various aspects of paid as well as unpaid forms of productive activity was mailed to stratified samples of male and female white collar workers, approximately matched for educational and occupational level. Data from 501 men and 679 women employed full time revealed traditional gender differences in terms of main responsibility for household duties, child care etc. In keeping with this, women reported higher levels of work overload, stress and conflict than men, which increased significantly with the number of children at home. The various stress indices reached a peak between the ages of 35 and 39. Men reported more autonomy in their paid work whereas women reported more control at home. Men and women at the upper managerial levels reported more control over their total work situation and less conflict between demands.  相似文献

Two studies were conducted, the first to establish a valid Spanish version of the Daily Stress Inventory (DSI). A second study was conducted using the bilingual version of the DSI to assess differences in the level of stress experienced by three selected Hispanic groups: (a) very Hispanic/Hispanic-oriented bicultural, (b) true bicultural, and (c) Anglo-oriented bicultural/very Anglicized as determined by the adapted version of the Acculturation Rating Scale for Mexican Americans (ARSMA). It was expected that stress levels would be highest for the least acculturated group. The results of the first study indicate that the Bilingual DSI scores are highly correlated with the scores of the original DSI when both instruments are responded to simultaneously by fully bilingual individuals. In Study 2, the initial data analyses showed no difference in the level of stress reported by Hispanics at different levels of acculturation as measured by the ARSMA. When a median-split method was employed, differences in the DSI I/E measures between the two groups were significant, suggesting that acculturation level may be related to stress level.  相似文献

Circular definitions,circular explanations,and infinite regresses   总被引:2,自引:0,他引:2  
This paper discusses some of the ways in which circular definitions and circular explanations entail or fail to entail infinite regresses. And since not all infinite regresses are vicious, a few criteria of viciousness are examined in order to determine when the entailment of a regress refutes a circular definition or a circular explanation.I would like to thank Professors Robert Tully, Howard Sobel, and Derek Allen for their constructive comments.  相似文献
