Such legal actions give rise to the question of risks and responsibilities accruing to social hosts who serve alcohol.

This paper introduces multilevel extensions for the general diagnostic model (GDM) following recent developments on extensions of latent class analysis (LCA) to hierarchical models. The GDM is based on LCA as well as discrete latent trait models and may be viewed as a general modeling framework for conrmatory multidimensional item response models.…

This paper compares the personal background characteristics and voting behavior of Wisconsin state legislators in two legislative sessions separated by 40 years (1965-1966 and 2005-2006). The study uses cluster analysis to graphically display the differences in the voting patterns of the two sessions, an indicator that can be used in this and…

Studies have suggested that professional learning is influenced by two key parameters, i.e., climate and planning, and their associated variables (mutual respect, collaboration, mutual trust, supportiveness, openness). In this paper, we applied analysis of the relationships between the proposed quantitative, fuzzy logic-based model and a series of…

This study examined patterns of performance on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) and the relationship of these patterns to diagnoses of behavioural problems. The sample consisted of 108 children between age 3 and 7 years inclusive who had been referred to a day-treatment program for a wide variety of…

The originally proposed multivariate meta-analysis approach for correlation matrices--analyze Pearson correlations, with each study's observed correlations replacing their population counterparts in its conditional-covariance matrix--performs poorly. Two refinements are considered: Analyze Fisher Z-transformed correlations, and substitute better…

The purpose of this study was to examine primary appraisal of sexual harassment, that is, a victim's cognitive evaluation of the harassment and the factors that influence this appraisal.

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.

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…

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…
