This paper is a contribution to the uses of life histories and the dialogue regarding the "standards" for their use. Through a meta-analysis of life histories in the United States since the publication of the Polish Peasant , we develop a typology to critically evaluate their methodological/theoretical practices in sociology. We find a broad range of uses of life histories in the areas of substantive focus, analysis, relationship of oral history and the subject, relationship of oral/life history to other materials, purpose of the research, and relationship of oral/life history to other phenomena. We conclude that life history methods have not had the transformative effect on sociology that they have had in other disciplines. By and large, the actual production of life histories continues to be a historical, to be characterized by abstract empiricism, to extinguish subjects, and to ignore the link between biography and history. 相似文献

Since the mid‐1980s, the incidence of sexually transmitted diseases (STDs) among Blacks has increased dramatically nationwide, particularly in Philadelphia and other major urban areas. One approach to this public health problem is to prevent the further transmission of disease through the use of condoms during sexual activity. To provide a basis for condom‐promotion programs within a high risk Black urban community, we explored condom use behavior and the relationship between condom use and variables related to demographic characteristics, knowledge, attitudes, perceived risk and concern about STDs, and STD history. A household survey was conducted of a stratified, quota sample of 925 male and female adolescent and adult residents in North and West Philadelphia. These areas have the highest rate of STDs in the city and among the highest rates in the country. The survey revealed a trichotomy among respondents with respect to condom use: approximately one‐third of the sample used condoms consistently; one‐third used them intermittently, and one‐third never used condoms. Consistent condom users tended to use condoms with both steady and casual partners; less frequent condom users tended to use condoms with partners who could be considered higher risk: new partners and casual partners. Although condom use rates did not vary as a function of age among males, women under age 20 were far more likely to use condoms than were other female age groups. Knowledge about STDs and prevention was not found to predict condom use. Negative attitudes toward condoms were related to non‐use, with the exception of women who used condoms in perceived high risk situations despite negative attitudes. 相似文献

Short-term forecasting of wind generation requires a model of the function for the conversion of meteorological variables
(mainly wind speed) to power production. Such a power curve is nonlinear and bounded, in addition to being nonstationary.
Local linear regression is an appealing nonparametric approach for power curve estimation, for which the model coefficients
can be tracked with recursive Least Squares (LS) methods. This may lead to an inaccurate estimate of the true power curve,
owing to the assumption that a noise component is present on the response variable axis only. Therefore, this assumption is
relaxed here, by describing a local linear regression with orthogonal fit. Local linear coefficients are defined as those
which minimize a weighted Total Least Squares (TLS) criterion. An adaptive estimation method is introduced in order to accommodate
nonstationarity. This has the additional benefit of lowering the computational costs of updating local coefficients every
time new observations become available. The estimation method is based on tracking the left-most eigenvector of the augmented
covariance matrix. A robustification of the estimation method is also proposed. Simulations on semi-artificial datasets (for
which the true power curve is available) underline the properties of the proposed regression and related estimation methods.
An important result is the significantly higher ability of local polynomial regression with orthogonal fit to accurately approximate
the target regression, even though it may hardly be visible when calculating error criteria against corrupted data. 相似文献

We administered the 18‐item Recalled Childhood Gender Questionnaire‐Revised (RCGQ‐R), female version, to 147 adult women with congenital adrenal hyperplasia (CAH) representing three different degrees of prenatal androgenization due to 21‐hydroxylase deficiency and to non‐CAH controls. A principal components analysis generated 3 components accounting for 46%, 9%, and 6% of the variance, respectively. Corresponding unit‐weighted scales (high scores = feminine) were labeled Gender Role (13 items; Cronbach α = .91), Physical Activity (3 items; a = .64), and Cross‐Gender Desire (2 items; α = .47). Discriminant validity was demonstrated in terms of highly significant comparisons across the 4 groups. We concluded that the first 2 RCGQ‐R scales show good psychometric qualities, but that the third scale needs to be evaluated further in a sample that includes women with gender identity disorder. 相似文献

Practice incorporating policy and political social work is a key component of the social work profession and an area in which students would benefit from exposure during social work education. Field education presents a significant opportunity for students to develop policy and political practice skills; however, individual and structural barriers may prevent students from developing practice experience in this area. Based on a survey of bachelor of social work and master of social work field directors in the United States, this field note examines the current state of policy and political practice field opportunities and examines barriers to offering such opportunities more widely. Ideas to facilitate these field opportunities, including curriculum-wide education about policy practice, relationship building, creativity, and identifying diverse placement sites, are presented. 相似文献

ABSTRACTExperiences of discrimination are associated with poor health and are particularly common among persons experiencing homelessness. Permanent supportive housing (PSH) provides a foundation for improved well-being among persons with homelessness histories, but research on discrimination among this population is limited. We examined changes in experiences of, and perceived reasons for, everyday discrimination when persons moved into PSH. 421 adults in Los Angeles County completed baseline (pre-housing), 3-, 6- or 12-month post-housing structured interviews. Generalized linear mixed models (GLMM) examined change in discrimination outcomes, controlling for demographic characteristics. Everyday discrimination experiences decreased significantly when persons moved from homelessness into PSH, and remained consistently lower across the first year in PSH. Reports of homelessness/poverty, race/ethnicity, and neighborhood as reasons for discrimination also decreased from baseline levels. PSH may offer respite from everyday discrimination, but the persistence of discrimination and particularly racism in society requires structural solutions addressing implicit bias and systemic inequities. 相似文献

ABSTRACTExperiencing sexual victimization prior to becoming homeless is common among homeless youth and is associated with increased HIV risk behavior. This study examined mediating variables that underlie this association, adding to the understanding of gender differences in these paths. Participants were homeless youth in Los Angeles recruited through service access centers who completed a computerized self-administered interview in English or Spanish using an iPad. Findings indicate a high presence of sexual victimization across both genders. Female participants experienced posttraumatic stress disorder and subsequent engagement with exchange sex, whereas male participants were primarily involved in substance use risk pathways. Results indicate paths in the association between sexual victimization and HIV risk behavior differ between male and female homeless youth. Gender-specific, mental-health-informed interventions targeting sexual risk reduction are warranted. 相似文献

The article examines how infants are first permeated by culture. Building on Thibault (2000), semiogenesis is traced to the joint activity of primary intersubjectivity. Using an African example, analysis shows how--at 14 weeks--an infant already uses culturally specific indicators of "what a caregiver wants." Human predispositions and the mother's enactment of cultural processes enable the child to give joint activity a specific "sense." Developmentally, the child prods the caregiver to shaping his or her actions around social norms that transform the infant's world. This nascent lopsided relation is probably necessary for learning to talk. Acting with its mother, the baby's full-bodied activity uses adult "understanding" in ways that are cultural, contingent, and indexical. Infant activity is already semiotic. 相似文献
