Samuels interviewed Dimen in lieu of a book review for her Sexuality, Intimacy, Power. The interview was unstructured and dialogical and covered the following main topics: (a) professional issues in the field of psychoanalysis such as the relation of theory to practice and reflections on the nature and content of trainings in psychoanalysis; (b) issues in the broad areas of sexuality and gender including the question of moral relativism with respect to sexual behaviors historically designated as “perverse” and considerations of masculinity, femininity, and patriarchy; (c) intellectual considerations such as the relations between anthropology and psychoanalysis and the as yet indeterminate nature of the discipline of psychoanalysis, neither art nor science and not a hybrid of the two; and (d) the political, social, and cultural contexts within which psychoanalytic endeavors including the interview itself are taking place.  相似文献

ABSTRACT

African American adolescents continue to be disproportionately impacted by HIV, sexually transmitted infections (STIs), and unanticipated pregnancies. In-depth, face-to-face interviews among a convenience sample of 32 African American adolescents (16 male and 16 female) were used to explore the reasons why some adolescents decided to engage in sex while others chose to delay sexual debut. Data were analyzed using a thematic analysis. Among the overall sample, psychological motivations, external pressure, physical pleasure seeking, and relationship-related motivations were the major themes cited for engaging in sex by participants and their friends. External support, motivation to avoid negative consequences, not feeling ready or lacking interest in sex, and having negative views about sex were among the major reasons for delaying sex. Several of the emergent themes showed gender differences. Suggestions for future research include the need for sexual education, and STI/HIV prevention programs that are gender sensitive and flexible enough to accommodate multiple factors related to sexual debut.  相似文献

Questioning why it is that female genitalia and desire are viewed in psychoanalytic theory as hidden, inaccessible, and lacking, the author examines 1) female genital representation, 2) girls' erotically desirous relationships to their mothers, and 3) the nature of women's experience in sexuality. The author proposes that the marker “absent” regarding female genitalia and desire may be a particular female form or protection against “castration” of sexual desire; males inflate whereas females may deflate their genital representation and desire. The author suggests that the female body lends itself-and, abetted by culture and psychoanalytic theory, is unconsciously used by females—to a specific form or protection of female desire.  相似文献

In a recent paper, Hampel (1985) studied the properties of rejection-plus-mean procedures as estimators of a location parameter. He reported that these procedures have low breakdown and high variance. In this article it is pointed out that these results are due to the outliers being rejected in a forwards-stepping manner, and when a more appropriate backwards-stepping approach is used, rejection-plus-mean procedures lead to estimators with high breakdown and high variance. In this article it is pointed out that these results are due to the outliers being rejected in a forwards-stepping manner, and when a more appropriate backwards-stepping approach is used, rejection-plus-mean procedures lead to estimator with high breakdown and redescending theoretical influence function.  相似文献

Abstract

Replication of an earlier survey, using the same questionnaire in the same college course, reveals an increase in proportion of male students with premarital heterosexual experience, from 45 per cent in 1943–44 to 61.8 per cent in 1967–68 and 74.9 per cent in 1969–73. While the mean number of episodes is also greatly increased, the tendency is toward reducing the number of partners. Since the proportion condoning premarital intercourse has risen to over 90 per cent, still further increments in activity may be anticipated. The number reporting homosexual behavior (most often limited to the pre‐ and early‐adolescent years) has declined from 27 per cent to 13.7 per cent, but the amount of activity during the college years has increased. Students having experienced a particular sexual activity impute that activity to a higher proportion of the general population than do the inexperienced.  相似文献

It appears to be common practice with ridge regression to obtain a decomposition of the total sum of squares, and assign degrees of freedom, according to established least squares theory. This discussion notes the obvious fallacies of such an approach, and introduces a decomposition based on orthogonality, and degrees of freedom based on expected mean squares, for non-stochastic k.  相似文献

This article contributes to studies of how inequities of power are naturalized in culture through the idea of “screen images,” a form of shared projective thinking. Screen images develop when socioeconomic reality contradicts shared cultural values and thus produces moral anxiety. The screen images we trace are those of the Lady and the Whore in bourgeois Victorian cultures, which we believe represented compromised versions of female sexual agency. Although these images originated in Victorian models of sexual difference, we show that they continue to shape models in 20th-century medicine, primatology, and evolutionary social science. These screen images reveal a historically persistent denial of agentive sexuality in women and have served as a defense through which people have avoided confronting the socioeconomic bases of gender inequality.  相似文献

In this paper, the bootstrap method of Efron (1979) is given for a ranking and a slippage problem, where the ranking (or slippage) is with respect to the mean of the distributions. The method is also applied to obtain a confidence interval for the largest mean.  相似文献
