Abstract“Women who have sex with women” or WSW have unique perspectives within the LBGTQ spectrum. The purpose of this study included documenting perceptions, feelings, and experiences among WSW. Thirty-seven women participated in six focus groups, ages ranged from 20–64 years. Responses were transcribed and thematically coded. Four themes emerged as influencing factors: shame and fear, community, gender roles, and normalcy. Each major theme produced minor themes providing a context within major themes. Results offer valuable insights that can assist community members, health professionals, and scientists to better appraise the disparities and stigma impacting social and emotional well-being among WSW. 相似文献

Conventional spirometry produces measurement error by using repeatability criteria (RC) to discard acceptable data and terminating tests early when RC are met. These practices also implicitly assume that there is no variation across maneuvers within each test. This has implications for air pollution regulations that rely on pulmonary function tests to determine adverse effects or set standards. We perform a Monte Carlo simulation of 20,902 tests of forced expiratory volume in 1 second (FEV1), each with eight maneuvers, for an individual with empirically obtained, plausibly normal pulmonary function. Default coefficients of variation for inter‐ and intratest variability (3% and 6%, respectively) are employed. Measurement error is defined as the difference between results from the conventional protocol and an unconstrained, eight‐maneuver alternative. In the default model, average measurement error is shown to be ~5%. The minimum difference necessary for statistical significance at p < 0.05 for a before/after comparison is shown to be 16%. Meanwhile, the U.S. Environmental Protection Agency has deemed single‐digit percentage decrements in FEV1 sufficient to justify more stringent national ambient air quality standards. Sensitivity analysis reveals that results are insensitive to intertest variability but highly sensitive to intratest variability. Halving the latter to 3% reduces measurement error by 55%. Increasing it to 9% or 12% increases measurement error by 65% or 125%, respectively. Within‐day FEV1 differences ≤5% among normal subjects are believed to be clinically insignificant. Therefore, many differences reported as statistically significant are likely to be artifactual. Reliable data are needed to estimate intratest variability for the general population, subpopulations of interest, and research samples. Sensitive subpopulations (e.g., chronic obstructive pulmonary disease or COPD patients, asthmatics, children) are likely to have higher intratest variability, making it more difficult to derive valid statistical inferences about differences observed after treatment or exposure. 相似文献

This article studies optimal taxation in a general equilibrium macroeconomic model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog preferences. Our economy is characterized by two distortions: a labor distortion due to the misalignment of markups on goods and leisure, and an entry distortion due to the misalignment of the consumer surplus effect and the profit destruction effect of entry. The two distortions interact in determining the wedge between the market‐driven and optimal level of product diversity. We show how optimal labor and entry taxes depend on the prevailing demand structure, the nature and size of entry costs, and the degree of substitutability between goods. (JEL E22, E61, E62) 相似文献

Many programs that place low-income students of color in high-achieving college preparatory high schools seek to nurture bridging social capital, connections across class lines that provide leverage in the process of “getting ahead.” Bonding social capital, which focuses more on emotional support and “getting by,” is frequently characterized as less useful for social mobility. Drawing upon in-depth interviews with alumni from one such program, we challenge the notion of bridging and bonding social capital as discrete, countervailing forms of social capital, and demonstrate how the two may complement each other. Specifically, we find that bonding social capital served as a critical resource that students drew upon as they navigated their elite high schools in the face of racism and classism. In doing so, this bonding social capital ultimately facilitated the development of bridging social capital by encouraging student persistence at these institutions. Our findings support critiques of traditional accounts of social capital that devalue the capital possessed by marginalized communities and fuel deficit ideologies. Furthermore, they highlight the personal costs that youth may face in the pursuit of bridging capital, complicating the narrative of social mobility as an unmitigated good. 相似文献

Many college students are using substances at levels consistent with Substance Abuse or Dependence, yet little explanation for this phenomenon exits. The aim of this study was to explore a risk factor profile that best separates those with low and high potential for having a substance use disorder (SUD). A discriminant function analysis revealed that participants with a high probability of having a SUD misperceive others' alcohol and marijuana use to a greater extent than those with a low probability of having a SUD. Implications for educators and counselors on college campuses are discussed. 相似文献

Objectives: Universities often promote their diversity as a selling point, but are students of different races at these universities integrated socially? Using theories on social energy, I examine racial segregation among university students. Methods: Quantitative data were collected on student residence patterns and social groupings formed at lunch tables at a case study university. In addition, interviews were conducted with 25 students. Results: Students are substantially more segregated than chance predicts. Blacks and Hispanics are particularly segregated. Interviews reveal that these students spend large amounts of social energy coping with prejudice and discrimination as well as functioning in a student culture they find unwelcoming and foreign. Conclusions: Social energy drains on minority students from discrimination and an unwelcoming campus culture reduce energy left for interracial interaction, making these racial groups more segregated. The study highlights the need for understanding segregation as a function of the interaction of out-group preferences, in-group preferences, and the larger social context. 相似文献
