Evaluations of Women and Men Among Black and White College Students1

Rainwater's assertion that blacks have low self-evaluations because they receive more negative evaluations from other blacks than whites receive from other whites is challenged here by reference to Heiss and Owens evidence that negative self evaluation among blacks is limited to work-related traits. Substantial support was found for our major hypotheses that, compared to whites, (1) blacks would report more negative evaluation of “most men” but not of “most women” (since the provider role is traditionally ascribed primarily to men), and (2) the more negative evaluation of “most men” by blacks would be limited to work-related traits.     

Parsons as a Symbolic Interactionist: A Comparison of Action and Interaction Theory1

Action theory's substantive image of social organization, theory building strategy, and methodological tenets are compared with those of interactionism. Despite polemics to the contrary, action and interaction concepts denote a similar image of social organization and personality. As is argued, the principle difference between the two perspectives revolves around the issue of the most appropriate theory building and methodological strategy. The ontological implications of this fact are examined and found not to justify the continued partitioning of social theory into antagonistic metaphysical camps.     

The last mile of the way: understanding caregiving in African American families at the end-of-life

This research is based on in-depth ethnographic interviews and focus groups with 88 African American family caregivers from various regions of the United States during a stressful time in their family development--caregiving at the end-of-life--and the grieving during the aftermath. The study employed a stratified purposeful sampling strategy. Subjects were African Americans from the Northern, Southern, and Midwestern United States. Formal care is complicated by the distrust that many African Americans hold toward the health care system, which has resulted from years of exclusion, racism and discrimination. The findings highlight the importance of hearing from African American families to gain an understanding of what services, including family therapy and other psychotherapy, they will need during this process.     

Stability of retrospective reports in depression: traumatic events,past depressive episodes,and parental psychopathology

Research findings based on the retrospective reports of depressed individuals have long been held suspect because of possible negative reporting biases associated with depression. In the present study we assess the stability of retrospective reports of past traumatic events, past depressive episodes, parental depression, and parental substance abuse in a sample of 234 adults whose depression status changed over two assessments conducted one year apart. Depression status was found to affect reporting of number of past depressive episodes and past traumatic events, but not reporting of parental psychopathology. Implications of these findings are discussed for research that relies on the retrospective self-reports of depressed participants.     

Extending private pension coverage in a middle-income country: the case of Brazil

Government policies can play an important role in the development of private pensions. These policies can be divided into three groups: (1) policies that are essential to providing a favorable economic environment for pensions; (2) policies that encourage the development of private pensions, given that a favorable economic environment for them exists; and (3) policies that deal with weaknesses of private pension systems. While the policies discussed are generally applicable for middle-income countries, the economic and legal environments for pensions differ across countries. This article focuses in particular on the situation in Brazil.     

Recursive location and scale estimators

It is shown that a recursive estimator with the same asymptotic properties as the median has convergence properties in finite samples which depend heavily on the scale of the data. A simple modification which adjusts for the scale is suggested and its application illustrated on simulated data. The modified estimator has much improved properties which are similar to those of the sample (non-recursive) median.     

Knowledge and Attitudes of University Health Service Clients about Genital Herpes: Implications for Patient Education and Counseling

Abstract

Genital herpes virus infection is an important target for health education efforts because of its apparently rising incidence in the college student population and because it can have potentially serious psychological as well as medical consequences. In order to better understand the health education and counseling needs of students, the present study surveyed knowledge and attitudes about genital herpes of 190 university students using a gynecology clinic and of 161 students using a general medical clinic. The students were found to have a high degree of familiarity with the disease, its cause, and mode of transmission, but tended to view the consequences of the disease as more severe than is actually warranted by the common medical complications. There was some degree of misinformation about prevention and treatment of the disease and some negative attitudes about patients suffering from it, but the survey respondents endorsed a high level of responsible behavior with regard to the disease and expressed some optimism about the possibility of adapting to it. These findings suggest specific misconceptions about genital herpes that might be amenable to a mass education approach. They also suggest the need for a counseling program that centers around reasonable reassurance and appropriately positive psychological and medical management for newly diagnosed patients.     

Estimating the propagation rate of a viral infection of potato plants via mixtures of regressions

A problem arising from the study of the spread of a viral infection among potato plants by aphids appears to involve a mixture of two linear regressions on a single predictor variable. The plant scientists studying the problem were particularly interested in obtaining a 95% confidence upper bound for the infection rate. We discuss briefly the procedure for fitting mixtures of regression models by means of maximum likelihood, effected via the EM algorithm. We give general expressions for the implementation of the M-step and then address the issue of conducting statistical inference in this context. A technique due to T. A. Louis may be used to estimate the covariance matrix of the parameter estimates by calculating the observed Fisher information matrix. We develop general expressions for the entries of this information matrix. Having the complete covariance matrix permits the calculation of confidence and prediction bands for the fitted model. We also investigate the testing of hypotheses concerning the number of components in the mixture via parametric and 'semiparametric' bootstrapping. Finally, we develop a method of producing diagnostic plots of the residuals from a mixture of linear regressions.
