Proposes a class of multivariate Tobit models with a factor structure on the covariance matrix. Such models are useful in the exploratory analysis of multivariate censored data and the identification of latent variables from behavioral data. The factor structure provides a parsimonious representation of the censored data. Models are estimated with…

For the exploratory analysis of a matrix of proximities or (dis)similarities between objects, one often uses cluster analysis (CA) or multidimensional scaling (MDS). Solutions resulting from such analyses are sometimes interpreted using external information on the objects. Usually the procedures of CA, MDS and using external information are…

Objective:: The objective was to examine the roles of cognition and affect in maternal use of physical punishment. Method:: Through a review of the literature, distal and proximal predictors (cognitive and affective) of physical punishment use were identified. One hundred and ten mothers of 3-year-old children were interviewed regarding two…

In this study we examined adolescent risk behaviors, giving special attention to suicide ideation. Cluster analysis was used to classify adolescents ( N = 2,730) on the Youth Risk Behavior Survey. Six clusters of adolescent risk behavior were identified. Although each risk cluster was distinct, some clusters shared overlapping risk behaviors.…

Data on 153 youth suicides in Arizona (1994?1999) were used to explore demographic, behavioral, and experiential factors that distinguish between firearm suicide and suicide by other means. In bivariate analyses, White youths were more likely than non-White youths to use a firearm to commit suicide as were youths who had not experienced a life…

Cluster analysis was used to identify groups defined by the patterning of fathers' and mothers' sources of knowledge about adolescents' experiences in a sample of 179 families with adolescents (M=16.5 years). Three clusters emerged for fathers (relational, relies on spouse, relies on others) and mothers (relational, questioners, relies on others).…

In Ontario, some court cases have involved attempts to sue social hosts for damage caused by the behaviour of drunken guests. Such legal actions give rise to the question of risks and responsibilities accruing to social hosts who serve alcohol. Using a sample of 1395 male and female adult residents of Ontario, the authors present self-report…

Research suggests that frequent, regularly scheduled quizzing is associated with pedagogically desirable outcomes such as higher performance on exams. It was hypothesized that requiring students to complete brief scheduled online quizzes on assigned reading material before class would also result in increases in both the number of in-class…

Purpose: The purpose of the paper is to determine possible grouping of similar MBA programmes offered by 45 British and French business schools accredited by the Association of Master Business Administration (AMBA) as of January 2006. Design/methodology/approach: The study uses the statistical co-plot method reported in a similar study of leading…

This article reports on the linguistic and pragmatic language skills of adults with a diagnosis of autism spectrum disorder (ASD). Seventeen adults (aged 18-67 years) with a diagnosis of ASD were assessed using the Western Aphasia Battery (WAB), the Right Hemisphere Language Battery (RHLB) and the Test of Nonverbal Intelligence-Second Edition…

This study used self-report symptom inventories administered in school classrooms to examine relations among gender, psychological symptoms, stress, and coping in 1,200 low-income African American urban early adolescents. Girls reported more symptoms than boys, accounted for by higher internalizing symptoms. Boys reported more stress than girls,…

This study identified factors that were potential predictors of student completion in a collegiate honors program, evaluated the relative predictive importance of these factors, and used them to describe how the completion groups differed. Records were examined from 336 freshman honors program participants at a large, Midwestern, public…

The role of education in fostering economic growth and social development is universally recognized. Although history places the provision of education firmly within national control, countries increasingly search outside national borders for alternative distribution frameworks. Tellingly, the World Trade Organization recently included education…

This article investigates the role that parental socioeconomic status plays in forming the racial gap in home computer use among young school-age children. Descriptive statistics from time diary data of 6- to 11-year-olds in the Panel Study of Income Dynamics, Child Development Supplement, reveal that Black American children spend substantially…

We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10-19, we identified five distinct…
