This study at 21 colleges found that having entering freshmen write a short holistically scored essay added nothing to the prediction of freshman grade point average compared to predictions made from high school grade point average, Scholastic Aptitude Test scores, and a multiple-choice test of writing-related skills.

Illustrates some applications of elementary probability and statistics to epidemiology, the branch of medical science that attempts to discover associations between events, patterns, and the cause of disease in human populations. Uses real-life examples involving cancer's link to smoking and the AIDS virus. (MDH)

A model for predicting organized youth sport participation readiness has four predictive components: sport-related fundamental motor skill development; sport-specific knowledge; motivation; and socialization. Physical maturation is also important. The model emphasizes the importance of preparing children for successful participation through…

Describes the practice of federal evaluation of research impact through three approaches: retrospective methods; qualitative methods, including peer review; and quantitative methods. Recommended areas for study in federal research impact assessment are suggested, including predictive reliability, comparative studies, time and cost estimates,…

Demographic impacts of meeting the National Health Objectives for 2000 were studied using life-table methods. Meeting the targets would increase life expectancy at birth by 1.5-2.1 years to 76.6-77.2 years. Modifying the coronary heart disease and unintentional injury targets to be more optimistic would further increase life expectancy. (SLD)

Argues that G. A. Cziko's conclusions about the inadequacy of mainstream educational research result from misunderstandings of statistical method, philosophy of science, and other topics. Perceptual control theory, which he espouses, may contribute for educational research but its potential does not result from shortcomings of mainstream…

The validity of using readiness tests for placing children in regular or 2-year kindergarten programs was studied in 9 Virginia school districts with a total enrollment of 17,662 in 1986-87. Four tests were evaluated; none were impressive predictors of performance on tests administered at the end of kindergarten. (SLD)

Students who accept the goal of becoming physicians early in life because of external pressures appear to have lower academic achievement than students who develop their professional identity because of personal abilities or interests. Data are from students (N=1156) attending the University of Michigan medical school between 1976-81. (MLW)

Examines responses of 40,435 students from the "Youth Risk Behavior Surveillance Survey" and uses student self-reported school risk behaviors to "predict" recent weapon possession at school. Although school risk behaviors were moderately correlated with school weapon possession, many frequent weapon carriers displayed zero…

Investigated the capacity of the Pharmacy College Admissions Test (PCAT) to predict success in pharmacy school. Found demographic differences in PCAT scores, and that the PCAT used in combination with pre-pharmacy grade point average is meaningful in assessing applicants to pharmacy school; applicants with PCAT composite percentile scores below 40…

The present analyses used depression-related items and co-factors from the National College Health Assessment (NCHA), Spring 2000. The results indicate 10.3 % of college students (6.2% male and 12.6% female) reported ever having been diagnosed with depression. Of those ever diagnosed with depression, 39% were diagnosed in the last year, 27% were…

Reactions to training programs tend to be poor predictors of training success, yet most training programs are evaluated based solely on trainee reactions. In this study, we proposed that distinguishing between affective and cognitive employee reactions may improve the prediction of trainee learning. Our results indicated that cognitive employee…

Despite readily available alumni survey data warehoused at many alumni associations and foundations across colleges and universities, researchers have underutilized the abundant available data to identify key predictors of alumni donation, including factors that trigger alumni donation behavior. Utilizing the data from a two-year alumni survey…

In this rejoinder, the authors respond to the insightful commentary of Strohmer and Arm, Chwalisz, and Hilton, Harris, and Rice about the meta-analysis on statistical versus clinical prediction techniques for mental health judgments. The authors address issues including the availability of statistical prediction techniques for real-life psychology…

The validity of estimates of peak oxygen consumption (VO[subscript 2]peak) using submaximal exercise tests may be compromised when the participants being tested are not similar to the participants used to develop the test. This study compared ethnic differences in the heart rate (HR) and oxygen consumption (VO[subscript 2]) responses to submaximal…
