We assess the relationship between skin color and educational attainment for native-born non-Hispanic Black and White men and women, using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. CARDIA is a medical cohort study with twenty years of social background data and a continuous measure of skin color, recorded as the percent of light reflected off skin. For Black men and women, we find a one-standard-deviation increase in skin lightness to be associated with a quarter-year increase in educational attainment. For White women, we find an association approximately equal in magnitude to that found for Black respondents, and the pattern of significance across educational transitions suggests that skin color for White women is not simply a proxy for family background. For White men, any relationship between skin color and attainment is not robust and, analyses suggest, might primarily reflect differences in family background. Findings suggest that discrimination on the basis of skin color may be less specific to race than previously thought.  相似文献

Research and clinical data have shown that couples with sexual problems report a lack of sexual communication. However, no published meta-analyses have evaluated the relationship between sexual communication and sexual function. This meta-analysis examines the correlation between couples’ sexual communication and dimension of sexual function across 48 studies. Sexual communication was positively associated with sexual desire (r = .16), sexual arousal (r = .21), lubrication (r = .17), orgasm (r = .23), erectile function (r = .19), less pain (r = .12), and overall sexual function (r = .35). The effect sizes for sexual desire (r = .21; r = .12) and orgasm (r = .26; r = .16) were higher for women than for men. For overall sexual function, studies with married participants (r = .47) had a larger effect size than studies with participants with multiple relationship types (r = .31) or than studies with dating participants (r = .11). Effect sizes were larger for studies conducted outside of the United States (r = .39) compared to studies conducted in the United States (r = .12). We discuss the importance of addressing the relationship between sexual communication and sexual function, as well as future directions for research in this area.  相似文献

Although difficulty conceiving a child has long been a major medical and social preoccupation, it has not been considered as a predictor of long-term outcomes in children ultimately conceived. This is consistent with a broader gap in knowledge regarding the consequences of parental health for educational performance in offspring. Here we address that omission, asking how resolved parental infertility relates to children’s academic achievement. In a sample of all Swedish births between 1988 and 1995, we find that involuntary childlessness prior to either a first or a second birth is associated with lower academic achievement (both test scores and GPA) in children at age 16, even if the period of infertility was prior to a sibling’s birth rather than the child’s own. Our results support a conceptualization of infertility as a cumulative physical and social experience with effects extending well beyond the point at which a child is born, and emphasize the need to better understand how specific parental health conditions constrain children’s educational outcomes.  相似文献

We report a study with sixteen low-SES Brazilian children that sought to establish a repertoire of relations involving dictated words, printed words, and corresponding pictures. Children were taught: (1) in response to dictated words, to select corresponding pictures; (2) in response to syllables presented in both visual and auditory formats, to select words which contained a corresponding syllable in either the first or the last position; (3) in response to dictated-word samples, to “construct” corresponding printed words via arranging their constituent syllabic components; and (4) in response to printed word samples, to construct identical printed words by arranging their syllabic constituents. After training on the first two types of tasks, children were given tests for potentially emergent relations involving printed words and pictures. Almost all exhibited relations consistent with stimulus equivalence. They also displayed emergent naming performances––not only with training words but also with new words that were recombinations of their constituent syllables. The present work was inspired by Sidman''s stimulus equivalence paradigm and by Skinner''s functional analysis of verbal relations, particularly as applied to conceptions of minimal behavioral units and creativity (i.e., behavioral flexibility) in the analytical units applied to verbal relations.  相似文献

We investigate parenting characteristics and adolescent peer support as potential moderators of the effects of childhood exposure to intimate partner violence (IPV) on adolescent outcomes. Lehigh Longitudinal Study (N=416) data include parent and adolescent reports of childhood IPV exposure. Exposure to IPV predicted nearly all adverse outcomes examined; however, after accounting for co‐occurring child abuse and early child behavior problems, IPV predicted only 1 outcome. Several moderator effects were identified. Parental “acceptance” of the child moderated the effects of IPV exposure on the likelihood of teenage pregnancy and running away from home. Both peer communication and peer trust moderated the relationship between exposure to IPV and depression and running from home. Peer communication also moderated the effects of IPV exposure on high school dropout. Interventions that influence parenting practices and strengthen peer support for youth exposed to IPV may increase protection and decrease risk of several tested outcomes.  相似文献

Sexual arousal is frequently characterized by both subjective (i.e., mental) and physiological (e.g., genital) components. The nuances of these components, however, are difficult to capture via self-report instruments. Asking women to describe sexual arousal in their own words may therefore enhance our understanding of this construct. In the present study, women with (n = 190) and without (n = 610) arousal concerns were recruited online and wrote about their experience of sexual arousal. Seven clusters of words were extracted using automated text analysis, and the prominence of these clusters was compared between groups of women. The autonomic arousal cluster differed between groups such that women with arousal concerns invoked this cluster significantly less than did women with no such concerns. Furthermore, the context cluster significantly predicted group membership (odds ratio [OR] = 1.063); greater scores on this cluster were associated with arousal concerns. Results suggest that autonomic arousal and relationship factors may play important roles in arousal concerns. It is suggested that clinicians assess for aspects of the sexual relationship that may facilitate or hinder sexual arousal. Clinicians may also consider inquiring about the presence or appraisal of autonomic arousal (e.g., one’s interpretation of an increase in heart rate or respiration) during sexual activity.  相似文献

Using longitudinal data from three demographic surveillance systems (DSS) and a retrospective cohort study, we estimate levels and trends in the prevalence and incidence of orphanhood in South Africa, Tanzania, and Malawi in the period 1988-2004. The prevalence of maternal, paternal, and double orphans rose in all three populations. In South Africa - where the HIV epidemic started later, has been very severe, and has not yet stabilized - the incidence of orphanhood among children is double that of the other populations. The living arrangements of children vary considerably between the populations, particularly in relation to fathers. Patterns of marriage, migration, and adult mortality influence the living and care arrangements of orphans and non-orphans. DSS data provide new insights into the impact of adult mortality on children, challenging several widely held assumptions. For example, we find no evidence that the prevalence of child-headed households is significant or has increased in the three study areas.  相似文献

In the lead-up to the Iraq War, the Bush administration rallied the American public for war via claims that they held unassailable evidence that Iraq possessed weapons of mass destruction and through the insinuation that links existed between Iraq and al Qaeda, and Iraq and the 11 September 2001 attacks. Despite the introduction of compelling evidence that these claims were false, more than 18 months after the official end of the war half of the American population continued to believe that either weapons of mass destruction had been found or that Iraq possessed a developed program for creating them. The prevalence of these misperceptions suggests important questions: How and why could such a significant percentage of the population remain so misinformed? What was the social process leading to the widespread adoption of misinformation? And what were the political effects of these misperceptions? This article proposes an analytical model that outlines both the production of these misperceptions and their political ramifications. It argues that the misperceptions about the Iraq war were socially produced via a complex interaction between a variety of factors including: the general climate of fear in America in the post-9/11 era, Bush administration agenda-setting strategies, and brokering between the political and communication establishments.  相似文献

In this paper, the research of Muse and Anderson is extended to include additional comparisons of designs, featuring planned unbalance, for the estimation of variance components in a two-way cross classification model. Their results are extended to Include the following: (i) a small sample study of the original off-diagonal (OD) design and (ii) an asymptotic maximum likelihood investigation of three modifica-tions of the balanced diagonal rectangles (BD) design and one modification of the 01) design to permit the estimation of row, column, interaction and error variance components. Also a general iterative least.  相似文献
