Discretized multivariate normal structural models are often estimated using multistage estimation procedures. The asymptotic properties of parameter estimates, standard errors, and tests of structural restrictions on thresholds and polychoric correlations are well known. It was not clear how to assess the overall discrepancy between the…

Minimization of the within-cluster sums of squares (WCSS) is one of the most important optimization criteria in cluster analysis. Although cluster analysis modules in commercial software packages typically use heuristic methods for this criterion, optimal approaches can be computationally feasible for problems of modest size. This paper presents a…

Dominance analysis (DA) is a method used to compare the relative importance of predictors in multiple regression. DA determines the dominance of one predictor over another by comparing their additional R[squared] contributions across all subset models. In this article DA is extended to multivariate models by identifying a minimal set of criteria…

There is little research on knowledge of the policy rules that could affect individuals, either in general or in evaluations of new programs. The lack of research is surprising, given that knowledge gaps could limit the effectiveness of reforms or lead to incorrect inferences regarding the effects of a policy change. In this article, we use survey…

Data include 603 Native American families, with reports from female caretakers and youths aged 10-13 years. Two potential caretaker influences are taken into account: adolescent modeling of…

The present research examined the relationship between self-concept and level of involvement in delinquent activities of 1327 (612 males, 715 females) years 8-12 high school students. Through cluster analysis, participants were identified as having either high or low involvement in delinquent activities from scores on a self-report measure of…

The authors describe an innovative technique for using Classification and Regression Tree (CART) with student characteristics, including geographical data for analyzing student enrollment patterns between students who enroll within a community college district (stayers) and those who enroll outside the district (movers) at neighboring community…

Idea evaluation has, in recent years, received more attention as a critical component of creative thought. One key influence on how people evaluate new ideas may be found in the standards, or attributes, people look for in appraising ideas. The intent of the present study was to examine the influence of different attributes on people's willingness…

The purpose of this study was to determine the effectiveness of a planned mastery motivational physical play session on physical activity (i.e., heart rate [HR] and physical play intensity [PAHR greater than 50]) in toddlers (N = 21), as compared to a nonplanned free play session. Participants wore a monitor to measure HR over two, 30 min play…

The role of superintendent of schools has become a hotbed of political focus in recent years. No longer is it sufficient for the designated leader of a school district to be an accomplished educator and respected person. In a climate of high expectations and blame placing, superintendents are expected to be all things to all populations. From…

Similarities and differences in adolescent siblings' free time activities were investigated. Firstborns and second-borns from 181 predominantly White, working, and middle-class families reported on their time use and sibling relationships. Their parents reported on their socioeconomic status and neighborhood characteristics. Cluster analysis…

Researchers have long searched for a relationship between school resources and student achievement. The search for this relationship has relied heavily on the use of education production functions. Despite years of research on this topic, there has been little agreement concerning which resources are the most essential variables to increase…

The authors analyzed delinquent development from age 12 to 32 in 270 male offenders who underwent residential treatment for problematic behavior and delinquency in a Dutch juvenile justice institution. Stable personality and background characteristics were measured on admission. The development of offending was examined on the basis of conviction…
