OBJECTIVE: This study compares homeless women who had childhood histories of foster care or other out-of-home placement to those who have not. METHOD: A countywide probability sample of homeless women (n = 179) received structured interviews. RESULTS: One-third of homeless women reported being raised apart from their parents. Among women with children under age 18, most (61.5%) had children who had lived in foster care or other out-of-home placements. Variables associated with homeless mothers' children living in foster care or other out-of-home placements were: Child was school-age, mother was age 35 or older, mother had a current alcohol or drug use disorder, mother experienced childhood sexual abuse, and mother ran away from home (when under age 18). CONCLUSIONS: Parenting is difficult for homeless mothers who may need to place their children with others to facilitate school attendance. Parent-child interaction may be problematic in family shelters where privacy is rare. Thus, programs promoting family preservation for homeless mothers should provide parenting support as well as permanent housing. 相似文献

Despite being a rather recalcitrant tool, the "Pap smear" is today the major cancer screening technology in the world. This paper examines how and why hetrogeneous actors chose to advocate the Pap smear as a screen for cervical cancer in the late 1940's, and to tinker both in and far beyond the diagnostic laboratory for over 50 years to make the Pap smear "fit" as a screening and clinical technology. Tinkerings included gendering the division of labour, attempting to automate reading of smears, juggling costs, exploring alternative screening technologies, pushing for regulation of laboratories, and settling for locally-negotiated orders of clinical accuracy instead of global standardization, still elusive today. 相似文献

The interactionist model (IM) of human development (R. D. Conger & M. B. Donellan, 2007) proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). Using a multigenerational data set involving 271 families, the current study finds empirical support for the IM. Adolescent personality characteristics indicative of social competence, goal-setting, hard work, and emotional stability predicted later SES, parenting, and family characteristics that were related to the positive development of a third-generation child. Processes of both social selection and social causation appear to account for the association between SES and dimensions of human development indicative of healthy functioning across multiple generations. 相似文献

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs,
few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research
projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging
undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey,
we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics
(STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory
relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive
government funding for their research are more likely to involve undergraduates in their research project(s). In addition,
faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in
research. Implications for advancing undergraduate research opportunities are discussed. 相似文献

Whilst many of us engage in supporting clinicians in identifying, appraising and using evidence, how many of us adopt the same approach to our own work? A recent survey by the UK LIS Research Coalition indicated that 60% of respondents use research reports as a source of information whilst a similar proportion of health library respondents use professional events such as conferences as a source of information. This summer sees the 6th International Evidence Based Library and Information Practice (EBLIP6) being held at the University of Salford, UK between 27th‐30th June which will go some way to satisfying this latter information need whilst the Health Information and Libraries Journal can help satisfy the need for research reports. Whatever you’re doing this summer, let’s make it evidence based. 相似文献

The agreement between self-reported and objective estimates of activity energy expenditure was evaluated in adolescents by age, sex, and weight status. Altogether, 403 participants (217 females, 186 males) aged 13-16 years completed a 3-day physical activity diary and wore a GT1M accelerometer on the same days. Partial correlations (controlling for body mass) were used to determine associations between estimated activity energy expenditure (kcal · min(-1)) from the diary and accelerometry. Differences in the magnitude of the correlations were examined using Fisher's r to z transformations. Bland-Altman procedures were used to determine concordance between the self-reported and objective estimates. Partial correlations between assessments of activity energy expenditure (kcal · min(-1)) did not differ significantly by age (13-14 years: r = 0.41; 15-16 years: r = 0.42) or weight status (normal weight: r = 0.42; overweight: r = 0.39). The magnitude of the association was significantly affected by sex (Δr = 0.11; P < 0.05). The agreement was significantly higher in males than in females. The relationship between activity energy expenditure assessed by the objective method and the 3-day diary was moderate (controlling for weight, correlations ranged between 0.33 and 0.44). However, the 3-day diary revealed less agreement in specific group analyses; it markedly underestimated activity energy expenditure in overweight/obese and older adolescents. The assessment of activity energy expenditure is complex and may require a combination of methods. 相似文献
