This paper briefly reviews the role that theory plays in organizing and guiding social work practice. Its major focus is on the specification and legitimation of important functions that social work practice assumes in the testing and developing of theory. The theory development functions are identified as theory reformulation, the redirecting of theory and the generation of new theory. Recognition is given to the selective utilization of theory derived from social science contexts but a greater emphasis is placed on developing theory directly from social work practice contexts.  相似文献

Prior research has demonstrated the link between maternal depression during pregnancy (i.e., prenatal depression) and increased neurodevelopmental dysregulation in offspring. However, little is known about the roles of key hypothalamic–pituitary axis regulatory genes in the placenta modulating this association. This study will examine whether placental gene expression levels of 11β‐hydroxysteroid dehydrogenase type 2 (HSD11B2), glucocorticoid receptor (NR3C1), and mineralocorticoid receptor (NR3C2) can help elucidate the underlying mechanisms linking prenatal depression to infant temperament, particularly in infants with high negativity and low emotion regulation. Stored placenta tissues (N = 153) were used to quantify messenger ribonucleic acid levels of HSD11B2, NR3C1, and NR3C2. Assessments of prenatal depression and infant temperament at 6 months of age were ascertained via maternal report. Results found that prenatal depression was associated with increased Negative Affectivity (p < .05) after controlling for postnatal depression and psychosocial characteristics. Furthermore, the association between prenatal depression and Negative Affectivity was moderated by gene expression levels of HSD11B2, NR3C1, and NR3C2 such that greater gene expression significantly lessened the association between prenatal depression and Negative Affectivity. Our findings suggest that individual differences in placental gene expression may be used as an early marker of susceptibility or resilience to prenatal adversity.  相似文献

This study examines the relationships between distorted cognitions, motivation, and alexithymia on problem gambling in poker players (n = 96). Respondents completed questionnaires containing the Canadian Problem Gambling Index, Gambling Motivation Scale, Gambler’s Beliefs Questionnaire, and Toronto Alexithymia Scale-20. The results suggest that problem gambling is significantly related to distorted cognitions, non-self-determined motivation, and difficulty identifying feelings. Implications are drawn for the development of more relevant intervention, prevention, and treatment strategies.  相似文献

The purpose of this study is to analyze the extent to which neighborhood‐level family structure and feelings of family integration are associated with acts of violence among 16,910 adolescents from the National Longitudinal Study of Adolescent Health. The results from our hierarchical linear models indicate that adolescents who live in neighborhoods with lower proportions of single‐parent families and who report higher levels of family integration commit less violence. We also find that neighborhood‐level family structure shapes the extent to which social integration into family matters: In neighborhoods that are considered higher risk environments (i.e., contain greater proportions of single‐parent families), family integration is often less effective in deterring youth violence than it is in lower risk environments.  相似文献

We investigated how future alternative designs for exurban residential subdivision development in agricultural landscapes might affect aquatic ecosystems and public perceptions, and we asked whether better aquatic ecological quality would correspond with public perceptions of greater landscape attractiveness. The alternative exurban futures we compared were: ecologically beneficial subdivisions, conventional subdivisions, and conventional agriculture. To judge their aquatic ecology effects we measured the chemistry and biota of six first-order streams within our study area, the Huron and Raisin River watersheds in the Detroit CMSA. We chose two stream catchments that exhibited land cover to represent the same proportions as each of three types of alternative exurban futures. Streams in catchments representing ecologically beneficial subdivision designs had the most total macroinvertebrate taxa, the most sensitive macroinvertebrate taxa, lowest nitrates, lowest total phosphorus, and lowest total suspended materials. Nutrient concentrations were highest in agricultural catchments, and suspended sediments were highest in conventional subdivision catchments. To compare public perceptions of the alternative futures, we surveyed 336 suburban and exurban adult residents of the upper Midwest. All respondents viewed digital imaging simulations of each of the futures and rated their attractiveness as if they were seen from the window of a home in the area. Ecologically beneficial futures were perceived as most attractive. Comparing the alternative futures, rankings of aquatic ecological quality were consistent with public perceptions of attractiveness.  相似文献

Because much of the existing research examining sexual communication to African American youth focuses on demographic and parental factors predicting sexual risk behaviors, less is known about factors predicting sexual health, and little is understood about the contributions of peer communications. The current study aimed to expand existing approaches by assessing which socialization discourses communicated by parents and peers contribute to sexual risk and health outcomes (sexual assertiveness, positive sexual affect, and condom self-efficacy). Participants were 631 African American undergraduates (73% female) who indicated the extent to which they had received from their parents and peers each of 28 messages representing four cultural discourses: abstinence, relational sex, sex positive, and gendered sexual roles. As expected, parents were perceived to emphasize relational sex and abstinence messages more than peers, and peers were perceived to communicate sex-positive and gendered sex role messages more than parents. Greater exposure to abstinence messages predicted lower levels of sexual experimentation, whereas exposure to sex-positive messages predicted higher levels. In addition, exposure to relational sex and sex-positive messages predicted higher levels of sexual assertiveness and positive sexual affect. Implications are discussed concerning sexual communications that could help Black youth develop healthy sexual perspectives.  相似文献

American Indians/Alaska Natives (AI/AN) suffer from some of the highest rates of health and mental health-related disabilities. Despite high rates of disabilities experienced among this population, services available to treat the disabilities are extremely limited, especially within the rural Alaska context. Additionally, limited research exists regarding the perceived barriers to receiving disability services, the importance of treating disabilities within one's own community, and individual and community-level strengths that exist to help cope with the lack of services. This article attempts to bring awareness to these issues, as well as propose tangible solutions to help mitigate the barriers.  相似文献

Despite governmental efforts and organizational initiatives, the number of disabled professionals in full‐time employment is small, and the number of those occupying leadership positions remains even smaller. Past research into disability and employment has outlined a range of barriers that disabled people face in seeking and maintaining employment. Yet, not enough is known about the challenges they encounter in top ranking appointments. This article extends Ryan's and Haslam's notion of the glass cliff to help explain the precariousness experienced by a group of disabled employees in leadership positions – focusing on the nature of the positions they hold and the difficulties they encounter as they attempt to advance their careers. Using qualitative interview data the analysis draws attention to problems associated with lack of opportunity, lack of resources and lack of support. It also point to ways of making workplace cultures and organizational practices more supportive of diversity.  相似文献
