Sexual orientation is often invisible in counseling research despite increasing LGBQ+ identity in the United States. We used consensual qualitative research to explore considerations from LGBQ+ counseling researchers for collecting sexual orientation. Three domains emerged: risks, benefits, and methodological considerations. Our findings highlight inclusive research practice strategies for LGBQ+ research participants. 相似文献

Although innovation diffusion is a central topic in policy and strategy, its measurement remains difficult – particularly in cases where the innovation is a complex and possibly ambiguous practice. In this paper, we develop four theoretical mechanisms that may bias diffusion markers by leading to the understatement and/or overstatement of diffusion at different points in time. Employing the case of “green chemistry,” we then compare three different diffusion markers – keywords, database index terms, and domain expert assessments – and we demonstrate how they lead to differing conclusions about the magnitude and timing of diffusion, organizational demography, publication outlets, and collaboration. We also provide suggestive evidence of extensive “greenwashing” by particular organization types and in particular countries. Building on these findings, we point to potential challenges with existing diffusion studies, and we make a case for the incorporation of practitioners in construct measurement and for the integration of comparative metrics in diffusion studies. 相似文献

The purpose of this study was to examine the role of sport as a social status determinant among racially diverse children. Participants were 1,233 fourth- to seventh-grade children. Results indicated there were gender, grade, and racial differences for the selection of social status determinants. Boys placed more importance than girls on being good at sports and wealth. Girls placed more importance than boys on getting good grades and being attractive. Fourth- and fifth-grade students ranked getting good grades as most important, while sixth- and seventh-grade students ranked being attractive as most important. Non-Hispanic Caucasian students ranked being good at sports and being attractive as most important, while African American students ranked getting good grades and wealth as most important 相似文献

The purpose of this study was to determine whether theoretically relevant sources of coaching efficacy could predict the measures derived from the Coaching Efficacy Scale II-High School Teams (CES II-HST). Data were collected from head coaches of high school teams in the United States (N=799). The analytic framework was a multiple-group confirmatory factor analysis with ordered-categorical indicators and observed covariates. Applying this framework to the conceptual model of coaching efficacy (CMCE) resulted in a statistical model equivalent to a multiple-group multivariate regression with latent outcomes. Results provided evidence for the ability of measures derived from the CES II-HST to be predicted by theoretically relevant sources of coaching efficacy and suggested modifications to the CMCE. 相似文献

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom. 相似文献

Let f(χ) together with its first two derivatives be continuous in the domain D and additionally let χM?D be an extremum (or turning point) of this function. Also, let χn+1 = T (χn,χn-1,χn-2) be Jarratt's Method for computing the extremum (or turning point) of a function. Criteria are demonstrated which insure that, for any triple of initial assumptions (χ1,χ0,χ-1)?D, Jarratt's Method, converges to the extremum of f(χ), and that from and after some n = N0, the rate of convergence of this method increases steadily, finally becoming unbounded when the solution χM is attained. 相似文献

This yearlong quasi experimental study examined the effects of two approaches to guided reading on second-grade students' reading abilities. The 79 subjects were chosen as a nonprobability sample and served as the treatment and comparison groups. The groups were pre- and post tested using the Developmental Reading Assessment, Second Edition determine students' reading levels. A 2 × 2 repeated measures analysis of variance revealed significant main and interaction effects. According to a post hoc analysis of mean difference effect size, both groups experienced very large effects, but treatment effects (d = 3.66) were much larger than the comparison (d = 1.34). The results suggest that increased emphasis on guided reading can lead to a greater impact on second-grade students' reading ability. 相似文献
