HIV risk and infection are markedly increased among sexual minority women injectors compared to other injecting drug users. Our ethnographic exploration of this well-documented but poorly understood phenomenon included 270 interviews and over 350 field observations with 65 sexual minority women injectors in New York City and Boston. We discuss findings in relation to four preliminary hypotheses. Neither the presence of gay or bisexual men in risk networks, nor a sense of invulnerability due to lesbian (or other sexual minority) identity seem to be plausible explanations of increased HIV among sexual minority women injectors. However, multiple marginalization was found to be pervasive and to have severe consequences that can be traced to increased HIV risk for many women in the study.  相似文献

This paper examines the differential salience of family and community demands and resources in relation to family-to-work conflict and facilitation. The study used interviews with 1567 employed, married, parents from the 1995 National Survey of Midlife Development (MIDUS). Family demands show relatively strong positive relationships to family-to-work conflict, whereas family resources are relatively important for family-to-work facilitation. Two community demands are positively related to family-to-work conflict and one community resource is positively associated with facilitation. Community demands and resources generally do not moderate relationships between family demands and resources and family-to-work conflict and facilitation. The study suggests that processes associated with demands are relatively important for family-to-work conflict, whereas processes embedded in resources are relatively salient for family-to-work facilitation.  相似文献

This study investigated physical activity and fitness of midlife and older rural women. Random-digit dialing was used to recruit 225 women (57.9 +/- 5.6 years old). Self-reported activity (moderate activity, flexibility, and strength) and fitness (body composition, flexibility, strength, and estimated VO(2max)) were assessed. The women demonstrated low daily energy expenditure (30.74 +/- 10.63 kcal x kg(-1) x day(-1)) and estimated VO(2max) (20.12 +/- 7.81 ml x kg(-1) x min(-1)), with 51.5% reporting fair or poor health. Few women reported meeting Healthy People 2010 targets for moderate activity (43.1%), flexibility (28.9%), or strength )14.2%). When classified by estimated VO(2max) into three categories, differences were observed for body-mass index, percent body fat, sit and reach, and timed chair stands, with the poorest performance by those with low cardiorespiratory fitness. Adherence to Healthy People 2010 targets for moderate activity and strengthening was associated with higher cardiorespiratory fitness. These rural women are targets for physical activity interventions because of their sedentary behaviors and low cardiorespiratory fitness.  相似文献

The authors explored relationships among childhood abuse, suicidal ideation, and sexual orientation of 18- to 30-year-old students enrolled in 2 San Diego area colleges, using responses from anonymous questionnaires. Sixty percent of the 138 eligible respondents were women, and 22% were self-identified gay/bisexual individuals. Women were more likely than men to report at least 1 form of emotional abuse (odds ratio [OR] = 2.3; p =.02) and unwanted sexual touching (OR = 4.3; p = .0004). Lesbian/bisexual women were significantly more likely to report past suicidal ideation than were heterosexual women (OR = 3.7, p = .03). Gay/bisexual men were more likely to report unwanted sexual touching than were heterosexual men (OR = 5.1, p = .04), but the men did not report significantly higher rates of past suicide ideation or suicide attempts. Sexual orientation and a past history of child sexual, physical, and emotional abuse could be compounding risk factors for suicidal ideation among college students.  相似文献

This study investigated nonverbal approach and avoidance behaviors exhibited by 30 families with a target child between 7 and 16 years old during a family interaction task. It was hypothesized that avoidance in the form of shame and contempt would be displayed more frequently by early and mid-adolescents than by younger pre-adolescents. It was also expected that approach behaviors would not differ across these age groups. Results provided evidence for increased avoidance and stability of approach behaviors in the parent-child dyad from pre-adolescence to mid-adolescence. Compared to pre-adolescent children (7–10), early adolescents (11–13) displayed more avoidance behaviors toward their parents, particularly shame. Both older adolescents (14–16) and their parents displayed increased avoidance in the form of reciprocated contempt. Despite increased avoidance in adolescence, no age group differences emerged in the amount of approach displayed between mothers, fathers, and children. This dynamic of attachment and separation occurred in both mother-child and father-child dyads, suggesting that both parents play an important role in the adolescent's developing autonomy.This research is based on the doctoral dissertation of Patricia E. Kahlbaugh under the direction of Jeannette M. Haviland at the Graduate School at Rutgers University. We thank the families who gave of their time to participate in this project and the individuals who helped in data recruitment, collection, and coding.  相似文献

Nakamura (1990) introduced an approach to estimation in measurement error models based on a corrected score function, and claimed that the estimators obtained are consistent for functional models. Proof of the claim essentially assumed the existence of a corrected log-likelihood for which differentiation with respect to model parameters can be interchanged with conditional expectation taken with respect to the measurement error distributions, given the response variables and true covariates. This paper deals with simple yet practical models for which the above assumption is false, i.e. a corrected score function for the model may not be obtained through differentiating a corrected log-likelihood although it exists. Alternative regularity conditions with no reference to log-likelihood are given, under which the corrected score functions yield consistent and asymptotically normal estimators. Application to functional comparative calibration yields interesting results.  相似文献

Consumer discount store patronage preferences for apparel are investigated using the concept of perceived risk. Apparel items are assigned a type and level of risk: low social, low economic; high social, low economic; and high social, high economic. Females (N=222) responding to a mail survey rate their willingness to purchase each item in a discount store on a scale ofprefer to buy, may buy, ornever buy. Results suggest that consumer preference for purchasing in discount stores declines more sharply when economic risk increases than when social risk increases.Teresa A.

This paper treats long-term care planning from a cultural perspective, that is, as a cultural system in which components of long-term care interlock culturally and therefore meaningfully. In the introduction and background sections, we provide a context in which long-term care planning may be viewed, based on the finding that relatively few people take advantage of long-term care planning and insurance; we also discuss some earlier work on long-term care from a psychological perspective that emphasizes themes of imagination and self-efficacy. We then examine long-term care from a cultural perspective by identifying and explicating five broad themes that help us better understand the meaning of long-term care planning to Americans. Finally, we use these themes to suggest some important social policy correlates.  相似文献

This article discusses the cross-cultural issues that confront immigrant Latino parents living and raising adolescents in the United States. Emphasis is placed on the need for social work practitioners, who, as they aid a family's integration into mainstream society, will listen to the parents' concerns and incorporate their past experiences and traditional culture into the assessment and treatment processes. Implications for practice, programs, and policy are also discussed.  相似文献

The effects of disasters may predispose many adolescents to psychological stress, which can interfere with their growth and development and disrupt their intrapsychic homeostasis. This may lead to negative long-term health outcomes and hamper normal development. Many nurses view traumatic events involving children, including adolescents, as the most frequent and stressful critical incidents. There is a need to address psychological emergency preparedness for mass disasters with the development of protocols and practice guidelines. Assessing and managing physical injuries may take priority in emergencies, but incorporating rapid, cost-effective mental health assessments for children and adolescents is essential.  相似文献
