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

In May 2002, the Denison Memorial Library at the University of Colorado Health Sciences Center and the J. Otto Lottes Health Sciences Library at the University of Missouri-Columbia, with funding from the National Network of Libraries of Medicine-Midcontinental Region, embarked on a collaborative, real-time reference project using the 24/7 Reference, Inc., software package. This paper describes how the project was conceived, and includes details on the service hours, staffing, training, marketing, lessons learned, and future plans for the service.  相似文献

Historical research benefits students of publishing in three ways. First, it provides an accurate account of what happened in the past. Second, by setting contemporary issues in a historical context, it helps identify trends. Finally, it encourages curiosity and learning about one’s cultural and intellectual heritage. Parker provides examples of research that serve these purposes. George L. Parker is professor and head of the Department of English and Philosophy at the Royal Military College of Canada, Kingston, Ontario. He teaches Canadian and American literature, has coedited an anthology,The Evolution of Canadian Literature in English: Beginnings to 1970, has contributed to theDictionary of Canadian Biography, and has publishedThe Beginnings of The Book Trade in Canada (1985).  相似文献
