Investigation of criterion-related validity of test scores of 107 deaf residential adolescents found concurrent validity between the Standard Progressive Matrices (SPM) and the Performance IQ of the Wechsler Intelligence Scale for Children-Revised, using both hearing and deaf norms. Predictive validity was supported by correlations between the SPM…

Job analyses were compared with employees' self-ratings of abilities across 54 occupations. Participants totaled 2,272 workers (1,119 women and 1,153 men) who took the Career Decision-Making System as part of an effort to expand its concurrent validity evidence. The results supported the validity of self-assessment of aptitudes in career…

Tests a model that posited that three diverse sets of academic outcomes for children were uniquely determined by psychological, family, and peer factors. Results reveal that early verbal skills are unique predictors of academic outcomes, and that the relative importance of psychological and peer factors depends on the kind of academic outcome of…

This study demonstrates the potential utility of the Behavioural Style Observational System (BSOS) as a new observational measure of children's behavioural style. The BSOS is an objective, short and easy to use measure that can be readily adapted to a variety of home and laboratory situations. In the present study, 160 mother-child dyads from the…

The actuarial Violence Risk Appraisal Guide (VRAG) was developed for male offenders where it has shown excellent replicability in many new forensic samples using officially recorded outcomes. Clinicians also make decisions, however, about the risk of interpersonal violence posed by nonforensic psychiatric patients of both sexes. Could an actuarial…

The main purpose of this study is to analyse the factorial structure, psychometric properties and predictive capacity for academic achievement of a scale designed to evaluate the time management skills of Spanish high school students. An adaptation of the Time Management Questionnaire was presented to two samples of 350 Spanish high school…

Two construals of agency are evaluated as possible innate biases guiding case-marking in children. A BROAD construal treats agentive arguments of multi-participant and single-participant events as being similar. A NARROWER construal is restricted to agents of multi-participant events. In Hindi, ergative case-marking is associated with agentive…

Mounting pressure in the policy arena to improve teacher productivity either by improving signals that predict teacher performance or through creating incentive contracts based on performance--has spurred two related questions: Are there important determinants of teacher productivity that are not captured by teacher credentials but that can be…

In their meta-analysis of clinical versus statistical prediction models, Aegisdottir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians' experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest…

The correspondence between the Hare Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) and the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) was examined in forensic (N = 175) and correctional (N = 188) samples. Intermeasure correlations for Total scores (0.95 forensic, 0.94…

Using data from the Iowa Youth and Families Project, this longitudinal study investigated the predictive validity of different dimensions of observed parent behavior on adolescent externalizing (aggression, hostility) and internalizing (depression, anxiety) problems over a 2-year period. In addition, the study examined how observer ratings…

Since university enrollment forecasting is very important, many different methods and models have been proposed by researchers. Two new methods for enrollment forecasting are introduced: (1) the fuzzy time series model; and (2) the artificial neural networks model. Fuzzy time series has been proposed to deal with forecasting problems within a…

In this paper, algorithms are described for obtaining the maximum likelihood estimates of the parameters in log-linear models. Modified versions of the iterative proportional fitting and Newton-Raphson algorithms are described that work on the minimal sufficient statistics rather than on the usual counts in the full contingency table. This is…

Educational research on the factors of student achievement has been limited by its failure to consider the multilevel or hierarchical nature of most data. This study used a nonexperimental regression-based procedure, hierarchical linear modeling (HLM), to empirically develop a predictive model of fifth-grade achievement in reading and mathematics…

At Cuyahoga Community College (CCC), the College-Level Examination Program (CLEP) for Introductory Macroeconomics Test was evaluated to determine if it was an effective tool for providing credit by examination for the college's Principles of Economics course. Though students at the present time (1991) can take the CLEP to obtain up to 45 credits…
