Within‐High‐School Versus Across‐High‐School Scaling of Admissions Assessments: Implications for Validity and Diversity Effects 下载免费PDF全文

Previous research has established that SAT scores and high school grade point average (HSGPA) differ in their predictive power and in the size of mean differences across racial/ethnic groups. However, the SAT is scaled nationally across all test takers while HSGPA is scaled locally within a school. In this study, the researchers propose that this difference in how SAT scores and HSGPA are scaled partially explains differences in validity and subgroup differences. Using a large data set consisting of 170,390 students each of whom matriculated at one of 114 separate colleges, the researchers find that awarding SAT scores by ranking SAT within a high school generally results in substantial reduction in the size of subgroup mean differences for this predictor. However, validity for predicting first‐year GPA is also reduced by a small amount. Conversely, placing HSGPA onto a nationally normed metric through the use of multiple regression procedures results in a moderate increase in the size of subgroup mean differences, while also producing a small increase in validity. Taken together, these findings suggest that differences in predictor scaling can partially explain differences in the size of subgroup mean differences between HSGPA and SAT scores and have implications for predictive power. 相似文献

This article investigates the effect of a Tony nomination or win on the demand facing a Broadway production using a panel
of weekly revenues for Broadway productions from 1996 to 2007. Our results indicate that the effect of a nomination or win
is positive in the week of the announcement and gradually increases in successive weeks, presumably due to publicity and word-of-mouth.
Winners experience an increase in demand as late as 1 year later when awards are publicized for the following season. Moreover,
nominees that do not win the award are penalized heavily in the weeks following the Award announcements. We find that winning
a Tony Award increases a production’s revenues by 12% in the week immediately following the Awards.

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise. 相似文献

A lot of the fun in contemporary sports talk relies on shared understandings about the culture of competitive sporting teams. The purpose of this paper is to explore how often humorous discourses are negotiated by sport fans as they narrate a sense of their own history and identity as followers of professional sports teams. This analysis draws on research conducted with followers of the Australian Football League (AFL), which included 21 life story interviews. As an oral historian, I was interested in how individuals negotiated popular ideas about Australian football in the ‘composition’ of their memories. This attention to the dynamic between the public and personal is described as a ‘popular memory approach’ to oral history. In this paper I explore the place of class in popular understandings about AFL club cultures. I argue that the role class plays in popular discourse around sporting club cultures is revealed more fully when we examine the ways in which individuals – in this case followers of AFL teams – make sense of it. 相似文献

Southern Illinois University Edwardsville (SIUE) has seen a dramatic increase in international student enrollment in the last four years. To serve this rising population effectively, librarians at SIUE created a research study to explore the information needs and academic experiences of international students at SIUE. The study employed a mixed-methods approach including a survey as well as in-depth interviews and photo diaries. The results provide insight into international students’ library use and academic life. 相似文献
