Research has shown that gay male couples’ sexual agreements may affect their risk for HIV. Few U.S. studies have collected dyadic data nationally from gay male couples to assess what sexual behaviors they allow to occur by agreement type and the sequence of when certain behaviors occur within their relationships. In our cross-sectional study, dyadic data from a convenience sample of 361 male couples were collected electronically throughout the United States by using paid Facebook ads. Findings revealed that couples discussed their HIV status before having unprotected anal intercourse (UAI) but established their agreement some time after having UAI. About half of the couples (N = 207) concurred about having an agreement. Among these couples, 58% concurred about explicitly discussing their agreement, 84% concurred about having the same type of agreement, and 54% had both men adhering to it. A variety of sexual behaviors were endorsed and varied by agreement type. Concordance about aspects of couples’ agreements varied, suggesting the need to engage couples to be more explicit and detailed when establishing and communicating about their agreements. The allowed behaviors and primary reasons for establishing and breaking sexual agreements further highlight the need to bolster HIV prevention for gay male couples.  相似文献

Using data from a nationally-representative cohort of young children in the United States, we ask the following: (1) Are there race/ethnic and birth weight differentials in the likelihood of developing respiratory problems by age three in a nationally representative birth cohort? (2) To what extent does birth weight, vis-á-vis other key sociodemographic risk factors, mediate race/ethnic differentials in reported respiratory problems? (3) Does the effect of birth weight on respiratory problems risk differ by race? We find that non-Hispanic black children are 1.7 times as likely as non-Hispanic white children to be reported to have respiratory problems by age three, while the risk for Hispanic children is similar to that of non-Hispanic white children. Birth weight is also very strongly related to respiratory problem risk. Specifically, children born at very low weights (500–1499 g) have four times the odds of having respiratory problems of heavier children. Statistical controls for birth weight decrease the black-white differential by about 20%, while additional controls for sociodemographic factors reduce the race differential by an additional 35%. Finally, the net effect of birth weight is different for black and white children: whereas birth weight affects the risk of respiratory problems for black children only at low weights (<1500 g), it remains an important predictor of excess risk for white children up to 3500 g.

Sixty-one foster parents from a central Canadian province participated in a telephone interview that included the question: “What are the benefits of fostering children who have the same values, beliefs and traditions as you?” A total of 51 unique responses were obtained and grouped together by 13 foster parents. Multidimensional scaling and cluster analysis were used to analyze the grouping data. Foster parents described five themes: expand on held values, child feels secure, smooth transitions, low stress and more in common. There were similarities and differences between the perspectives of foster parents interviewed and the literature. Implications for future research are discussed.  相似文献

Reports of falsification, fabrication, plagiarism, and other violations of research integrity across the sciences are on the increase. Joining with other disciplines to actively protect the integrity of the marriage and family therapy (MFT) research literature is of utmost importance to both the discipline and the future of the profession. To inform the issues raised, results are presented of an informal survey among MFT clinical members on their perceptions about the literature together with their preferences for how best to protect its integrity. This article initiates an important discussion about the honesty of MFT research.  相似文献

We assessed beliefs about adult children’s responsibilities to financially assist parents and stepparents following later-life divorce and remarriage using a multiple-segment factorial vignette with a national sample (N = 1,121). Ordered logistic regression analyses indicated that beliefs about financial responsibilities to older adults declined after marital transitions, and responsibilities to assist stepparents were more tenuous than to parents. Beliefs about intergenerational responsibilities were affected by adult children’s financial resources and by changes in older adults’ marital statuses. Kinship obligation norms, the adult children’s financial resources, and reciprocity norms were the most common reasons used to explain beliefs about responsibilities to financially assist older parents and stepparents, but these reasons became less salient following divorce and remarriage of the older adult. After marital transitions, beliefs about intergenerational financial responsibilities were more often based on the older adult’s culpability for being in a position of need, relationship quality, and diminished kinship obligations.  相似文献

How do parents influence adolescent risky behavior? In this paper, we focus on a unique population: children of the clergy, more commonly known as preachers’ kids (PKs). We used data on risky behavior among American adolescents from the National Longitudinal Survey of Youth 1979 Cohort and used latent variable and zero-inflated count models to analyze the effect of being a PK on both uptake and intensity of use of alcohol, cigarettes, marijuana, and other drugs. We found that being a PK significantly reduced alcohol use. This effect came exclusively from a reduction in the probability of any alcohol use and this increased abstinence among children of the clergy persisted into adulthood. We found no significant effects of being a PK on cigarette uptake or intensity of use but some evidence of a negative PK effect on the uptake of marijuana and other drugs.  相似文献

Aboveground forest carbon sequestration is known to be a function of allometric relationships, stand history, and edaphic conditions. We investigate how the heterogeneous edaphic conditions of a naturally assembled urban brownfield influence the allometric relationships of the dominant species Betula populifolia Marsh. We measured diameter at breast height (DBH), height, mass and age on four sites that exhibited considerable edaphic differences. Site conditions did not appear to impact total tree mass to diameter relationships. However, mean DBH at the various sites ranged from 6.7 to 9.8 cm and the mean height from 637.4 to 911.8 cm. In addition, above ground woody biomass ranged from 40017 to 71935 kg ha?1. Apparently resource allocation between growth and maintenance within the heterogeneous edaphic conditions of the urban context clearly results in considerably different growth rates and stocking densities. These results help to establish accurate metrics for the development of inventory-based forest carbon allocation models within the difficult environs of the urban context.  相似文献

Intimate partner violence is a common and damaging experience for many couples, and therapists struggle to address it adequately (Johnson, 2008). Despite its negative effects, many violent couples stay together, with some stopping their violent behaviors. Unfortunately, we know little about the systemic factors affecting violence desistance. This study used grounded theory methods to analyze the process of desistance in formerly violent couples. A model of desistance consisting of three categories was developed, which for most couples included a (a) Turning Point, (b) Decision to Change, and (c) Doing Things Differently. Therapists are encouraged to use the model to better understand the varied and systemic nature of violence and desistance, and to make more sophisticated decisions about referral and treatment.  相似文献

Research focusing on disparities in academic achievement among Black, African American, and other youth has largely examined differences in quantitative risk and protective factors associated with levels of achievement. Few interpretive studies of academic achievement by race or ethnicity have considered how the context of young people’s lives impact their perceptions of academic performance. Furthermore, the lived experiences of Black and African American youth have rarely been considered. This study examined perceptions of academic achievement among a sample of Black and African American elementary and middle school students living in four public housing neighborhoods in a Western US city. Twenty-five Black and African American youth participated in the study. Fourteen youth were in grades 4 and 5, and 11 youth were in grades 6, 7, or 8. Sixty-four percent of participants (n?=?16) were male and 36% (n?=?9) were female. Four themes emerged regarding participants’ perceptions of academic achievement: (1) (in)equity and the internalization of messages; (2) teachers as gatekeepers; (3) family and community factors promoting and inhibiting academic success; and (4) cultural considerations—language, stereotypes, and difference. Implications for improving academic outcomes and reducing the achievement gap among Black, African American, and other students are noted.  相似文献

Gay and bisexual men are at disproportionate risk for human immunodeficiency virus (HIV) infection. While prevention efforts often emphasize consistent condom use, there is growing evidence that men are using seroadaptive safer-sex strategies, such as serosorting and seropositioning. This qualitative analysis of 204 HIV-negative and HIV-positive gay and bisexual men explored the ways that a sexual partner’s HIV status can influence safer-sex strategies and sexual decisions. The majority of the respondents reported that they were influenced by their partners’ HIV status. Those respondents who reported no influence discussed adhering to safer-sex rules that were not dependent on partner status and a lack of concern about HIV. Conversely, respondents who reported influence identified three primary areas of influence: psychological impacts, partner preference and selection, and specific behavioral intentions and strategies. A conceptual model explicating a potential process by which respondents use partner serostatus information in shaping sexual decisions is presented.  相似文献
