To predict suicide, explicit causal models of suicide outcome are needed in which predictors are temporally ordered and then tested statistically. Because suicide is a dichotomous, nominal scale outcome, only certain statistics for prediction are appropriate. Logistic regression, which utilizes the likelihood ratio test of statistical inference,…

Developed a simulation model to predict the effects of policies for reducing adolescent smoking initiation. The model projected numbers of smokers, never smokers, and ex-smokers by age, sex, and race/ethnicity and effects of reductions in youth initiation. Results predicted that even if tobacco policies eliminated youth initiation, the number of…

Until recently, no self-report instruments have examined psychological skills use in both practice and competition. In light of the significant role of practice in sport performance outcomes, a need exists to measure these skills in both domains. This study was designed to investigate differences in performance strategies of US Olympians in both…

This paper reports analysis of 2006-2007 on-entry assessment data from the Performance Indicators in Primary Schools Baseline Assessment (PIPS-BLA) of random samples of students in England, Scotland, New Zealand and Australia. The analysis aimed, first, to investigate the validity and reliability of that instrument across countries and sexes, and,…

National background of users may influence the process of technology acceptance. The present study explored this issue with the new, integrated technology use model proposed by Sun and Zhang (2006). Data were collected from samples of college students in India, Mauritius, Reunion Island, and United States. Questionnaire methodology and…

In textbooks, foreign (second) language reading proficiency is often evaluated through comprehension questions. In case, authentic texts are used as reading material, such questions should be prepared by teachers. However, preparing appropriate questions may be a very demanding task for teachers. This paper introduces a method for automatically…

The standards-based reform movement has resulted in the wide-spread use of summative assessments designed to measure students' performance at specific points in time. While many have hoped that these end-of-year tests would provide constructional useful information for educators, they do not. This is not because there is something…

Academic achievement indices including GPAs and MCAT scores are used to predict the spectrum of medical student academic performance types. However, use of these measures ignores two changes influencing medical school admissions: student diversity and affirmative action, and an increased focus on communication skills. To determine if GPA and MCAT…

An empirical model was developed to represent the organization of the value-attitude system as postualted by Rokeach, and the model was used to determine the internal consistency of the system, its structure and components, and the extent to which the system permitted the prediction of attitudes from values.

This study attempted to apply the statistical technique of multiple discriminant analysis to the prediction of homicidal behavior by use of the Rorschach. (Author/RK)

Theoretical analysis of two idealized discrimination situations show that certain assumptions of habit strength development need not result in differentiated predictions for the performance of two drive-level groups when the numbers of occurences of responses are equated. (Author)

The abilities of the Henmon-Nelson, Cardall-Miles, Slosson and Quick Tests to predict WAIS-FS scores in a psychiatric hospital were compared. (Author)

This technical manual discusses some of the recent developments in the science of graphology and their implications for the science. The manual contains the following sections: (1) Graphology: An Introduction; (2) "CHAPS": Computerized Handwriting Analysis Profiling Systems; (3) HRC Profiles; (4) Reliability; (5) Validity; (6) Historical…

A specific application of a general paradigm described by R. D. Cook (1986) and R. McCulloch (1985) in assessing local influence is given. Snow geese flock size is estimated as "X" by an observer and "Y" by a photograph. "Y" is believed to be the true flock size. The problem is to obtain true flock size "Z"…

The study examines the validity of the ACE and selected subscales of the EPPS and SVIB in predicting the vocational performance of engineers. The only consistent finding was that subjective ratings of vocational performance were predicted by SVIB Group V scores; a "self-esteem" interpretation was posited. (Author)
