This study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (Mage = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners. 相似文献
This study examined development of emotional support competence within close friendships across adolescence. A sample of 184 adolescents (53% girls, 47% boys; 58% White, 29% Black, 14% other identity groups) participated in seven waves of multimethod assessments with their best friends and romantic partners from age 13 to 24. Latent change score models identified coupled predictions over time from emotional support competence to increasing friendship quality and decreasing support received from friends. Friend-rated emotional support competence in adolescence predicted supportiveness in adult romantic relationships, over and above supportiveness in adolescent romantic relationships. Teen friendships may set the stage for developing emotional support capacities that progress across time and relationships into adulthood. 相似文献
Early studies and theory suggest sexual minorities are drawn towards the relative independence of self-employment to avoid discrimination in paid employment. However, recent evidence is mixed, suggesting that a higher propensity for self-employment (relative to heterosexual people) is found only among lesbian women relative to heterosexual women. This study overcomes the data limitations of prior research by using data pooled from 2007–2017 cycles of the Canadian Community Health Survey (CCHS) and multivariate logistic regression to provide new evidence on LGB self-employment. The results show that self-employment is particularly high for bisexual people, especially bisexual women—but not for gay men or lesbian women. Overall, this study examines the enduring but nuanced relationship between self-employment and sexual orientation and discusses countervailing factors related to socio-economic resources, gender, and family structure. 相似文献
Families experiencing homelessness report higher rates of traumatic exposure than the general population, and traumatic experiences can often be precipitating factors for entrance into a homeless shelter. Emergency shelter is meant to be a brief, temporary housing intervention to support families toward more stable and permanent living arrangements. Beyond this ecological intervention, there is a frequently unmet need for trauma-specific mental health services. Further still, psychosocial interventions to support sheltered families should be sensitive to both the trauma-specific needs of this population and the constraints of the shelter setting. The Child and Family Traumatic Stress Intervention (CFTSI) is a brief, secondary prevention protocol that aims to prevent PTSD after exposure to a traumatic event, with research demonstrating its effectiveness in acute care settings such as child advocacy centres and emergency departments. This case study illustrates the implementation of CFTSI in an emergency family shelter in a large urban area, highlighting the appropriateness of the intervention for the setting, its adaptability to client needs and its generalizability to other non-traditional intervention settings. 相似文献
We discuss the identification and estimation of discrete games of complete information. Following Bresnahan and Reiss (1990, 1991), a discrete game is a generalization of a standard discrete choice model where utility depends on the actions of other players. Using recent algorithms to compute all of the Nash equilibria to a game, we propose simulation‐based estimators for static, discrete games. We demonstrate that the model is identified under weak functional form assumptions using exclusion restrictions and an identification at infinity approach. Monte Carlo evidence demonstrates that the estimator can perform well in moderately sized samples. As an application, we study entry decisions by construction contractors to bid on highway projects in California. We find that an equilibrium is more likely to be observed if it maximizes joint profits, has a higher Nash product, uses mixed strategies, and is not Pareto dominated by another equilibrium. 相似文献
Green roof systems have been increasingly implemented to enhance vegetation cover and associated ecosystem services in urban spaces, with primary goals being the reduction of peak surface runoff, enhanced water quality, and mitigation of urban heat island effects. Recently, green roofs have also received attention as a means to enhance carbon sequestration, but direct measurements of greenhouse gas fluxes from established green roof systems are largely lacking. Here we present observations of CO2 and CH4 fluxes from substrates of experimental extensive green roof units that varied in vegetation type (Sedum spp., and a native meadow species mix), substrate depth, substrate type (high vs. low organic matter content), and irrigation. We predicted that substrate CO2 effluxes would be higher in high-organic-matter substrates and that systems with high organic matter would potentially act as CH4 sources. Substrate fluxes were low compared to natural soils, with seasonal means ranging from an efflux of 0.1–0.4 µmol CO2 m-2.s-1 and uptake of ~0.00–0.04 nmol CH4 m-2.s-1, with higher fluxes late in the growing season. CO2 fluxes showed large increases in response to irrigation and were higher from the high-organic-matter substrate and with increased substrate depth. The strength of the CH4 sink increased in response to prior irrigation treatments, and CH4 emissions were detected only on low-organic-matter substrates early in the growing season. No effects of vegetation type were detected for either CO2 or CH4 flux. Our results indicate that high levels of organic matter in green roof substrates may enhance aerobic soil respiration but are not associated with CH4 emissions, which instead were only detected in low-organic-matter substrates.

This 2-year longitudinal study examined Mexican-origin adolescents’ need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors). Prosocial behaviors, which are actions intended to benefit others, are hallmarks of social proficiency in adolescence and are influenced by intrapersonal abilities and motivations that typically develop during adolescence. Yet, few studies of Mexican-origin or other U.S. Latinx youths have examined whether such individual difference characteristics, specifically social motivation and emotion regulation skills, support prosocial behavior. In a sample of 229 Mexican-origin youth (Mage = 17.18 years, SD = .42, 110 girls), need to belong, cognitive reappraisal, and general prosocial behaviors were assessed at ages 17 and 19. Emotional and public forms of prosociality also were assessed at age 19. Cognitive reappraisal was positively associated with concurrent general prosociality at age 17, whereas need to belong was positively associated with concurrent public prosociality at age 19. Moderation analyses revealed that general and emotional types of prosocial behaviors at age 19 were lowest for youth with both lower need to belong and less use of cognitive reappraisal at 19 years. Greater cognitive reappraisal skills and need to belong may reflect distinct motivations for engaging in varying forms of prosocial behavior in late adolescence. 相似文献
High levels of prenatal alcohol exposure (PAE) result in significant cognitive deficits in children, but the exact nature of the dose-response relationship is less well understood. To investigate this relationship, data were assembled from six longitudinal birth cohort studies examining the effects of PAE on cognitive outcomes from early school age through adolescence. Structural equation models (SEMs) are a natural approach to consider, because of the way they conceptualise multiple observed outcomes as relating to an underlying latent variable of interest, which can then be modelled as a function of exposure and other predictors of interest. However, conventional SEMs could not be fitted in this context because slightly different outcome measures were used in the six studies. In this paper we propose a multi-group Bayesian SEM that maps the unobserved cognition variable to a broad range of observed outcomes. The relation between these variables and PAE is then examined while controlling for potential confounders via propensity score adjustment. By examining different possible dose-response functions, the proposed framework is used to investigate whether there is a threshold PAE level that results in minimal cognitive deficit. 相似文献
