This article discusses the political clout wielded by a group of white women who participate in “Presidents’ Committee,” an organization of Parents Association presidents in a New York City Community School District. The school district, like many urban areas, is experiencing an exodus of white families to the suburbs, which are seen as offering better resources and a safe social distance from blacks and other non‐whites. In this context of social change, white mothers who participate in Presidents’ Committee push at gender boundaries in the public sphere by professionalizing motherhood and watching over potentially corrupt political practices. At the same time, their activism can be understood as a key component of local efforts to reproduce “white” community. Through this ethnographic analysis, “whiteness” is unpacked as a construct that is fractured by gender, class, and place of origin, while remaining a resilient idealized resource with which to reproduce a black/white racial binary.  相似文献

ABSTRACT

This qualitative study describes the adolescent sexual development of ten African American gay men living with AIDS. The informants retrospectively describe the challenges of being a gay adolescent in a mostly heterosexist and homophobic environment. They report unsupportive homophobic and heterosexist family members, community members and school officials. They also describe their burgeoning sexual orientation, sexual initiation as well as consensual and non-consensual sexual experiences with their peers. Additionally, several informants describe seeking sexual experiences with adult men. Later they suggest the adult men became their primary sources of emotional and psychological support. Implications for community practice, intervention and research with both African American gay adolescents and adult men living with AIDS are discussed.  相似文献

Parents and adolescents (mean age, 15.7 years) from 177 adoptive families participating in the second wave of the Minnesota/Texas Adoption Research Project were interviewed about their post-adoption contact arrangements. The sample included families with no contact, stopped contact, contact without meetings, and contact with face-to-face meetings between the adolescent and birth mother. Openness arrangements were dynamic, and different openness arrangements were associated with different experiences and feelings. Adoptive families with contact reported having higher levels of satisfaction about their openness arrangements, experiencing more positive feelings about the birth mother, and possessing more factual and personal knowledge about the birth mother than did families without contact. Adolescents and adoptive mothers in the contact with meetings group reported the greatest satisfaction with their openness arrangements; those with no contact or stopped contact reported the least satisfaction with their arrangements. Participants having no contact were more likely to want the intensity of contact to increase in the future rather than stay the same. Many participants already having contact wanted it to increase in the future. Fewer than 1 percent of all participants wanted to see the intensity of contact decrease.  相似文献

‘Classical’ genomic progesterone receptors appear relatively late in phylogenesis, i.e. it is only in birds and mammals that they are detectable. In the different species, they mediate manifold effects regarding the differentiation of target organ functions, mainly in the reproductive system. Surprisingly, we know little about the physiology, endocrinology, and pharmacology of progesterone and progestins in male gender or men respectively, despite the fact that, as to progesterone secretion and serum progesterone levels, there are no great quantitative differences between men and women (at least outside the luteal phase). In a prospective cohort study of 1026 men with and without cardiovascular disease, we were not able to demonstrate any age-dependent change in serum progesterone concentrations. Progesterone influences spermiogenesis, sperm capacitation/acrosome reaction and testosterone biosynthesis in the Leydig cells. Other progesterone effects in men include those on the central nervous system (CNS) (mainly mediated by 5α-reduced progesterone metabolites as so-called neurosteroids), including blocking of gonadotropin secretion, sleep improvement, and effects on tumors in the CNS (meningioma, fibroma), as well as effects on the immune system, cardiovascular system, kidney function, adipose tissue, behavior, and respiratory system. A progestin may stimulate weight gain and appetite in men as well as in women. The detection of progesterone receptor isoforms would have a highly diagnostic value in prostate pathology (benign prostatic hypertrophy and prostate cancer). The modulation of progesterone effects on typical male targets is connected with a great pharmacodynamic variability. The reason for this is that, in men, some important effects of progesterone are mediated non-genomically through different molecular biological modes of action. Therefore, the precise therapeutic manipulation of progesterone actions in the male requires completely new endocrine-pharmacological approaches.  相似文献

Although there is substantial evidence linking marital quality to physical health, few studies have been longitudinal. This study examined data from the Marital Instability Over the Life Course Study; 1,681 married individuals followed for 20 years were included in these analyses. In order to control for life course effects, participants were divided into 2 cohorts: early life and midlife. On the basis of latent growth curve analysis, the results indicated that initial values of marital happiness and marital problems were significantly associated with the initial value of physical health among both cohorts. In addition, the slope of marital happiness was significantly associated with the slope of physical health among the younger cohort, and the slope of marital problems was significantly associated with the slope of physical health among the midlife cohort. These results provide evidence of the significant association between positive and negative dimensions of marital quality and physical health over the life course.  相似文献

Abstract

A review of the literature of counterculture-inspired efforts at organizing alternatives to commercialism and technocracy reveals that the duration of many of these organizations was quite short. However, in spite of a general fading away of the larger counterculture, some of these efforts did indeed survive. Among the survivors are the crisis centers, organizations originally seeking to provide nondirective, empathetic, problem-solving help to individuals undergoing a personal crisis. An analysis of a sample of crisis centers based in midwestern states reveals that the internal structure of most of them has, with the passage of time, become increasingly formalized. Furthermore, many of these alternative organizations now serve persons who are less socially marginal and more socially acceptable than were the centers' original clients. Our results seem to suggest that, for both internal organizational reasons and external societal reasons, such groups may provide feelings of worth for their members but often change their initial goals somewhat. Also, despite their initial commitment to a less bureaucratic structure alternative organizations in fact become more bureaucratic.  相似文献

Abstract

A marked pattern of area-to-area differences in violence is described for Northern Ireland during 1969–74. Violence, measured by death rates, is especially high in the two largest cities and in the southwestern area. Two variables which together account for most of the area variation in violence are population density and proportion Roman Catholic. These findings underline the relative importance of group mobilization for political challenge as a basis of recent Ulster violence.  相似文献
