A varying abstraction framework for categorization. Manuscript submitted for publication; Vanpaemel, W., Storms, G., & Ons, B. (2005). A varying abstraction model for categorization. In B. Bara,…

This paper examines men and women methamphetamine (meth) users who participated in a community-based drug court. The treatment of female drug users is a particularly salient issue because of the concerns with relapse and recidivism. For the current study, we studied the impact of the drug court by gender on a group of high-risk/high-need meth…

We discuss aspects of multivariate fMRI modeling, including the statistical evaluation of multivariate models and means for dimensional reduction. In a case study we analyze linear and non-linear dimensional reduction tools in the context of a "mind reading" predictive multivariate fMRI model.

Two well-cited studies (Garner, Garfinkel, Schwartz & Thompson, 1980; Wiseman, Gray, Mosimann, & Ahrens, 1992) examined the changing body shape of Playboy centrefolds from 1959 to 1988 and noted that their body weights were significantly lower than those of the average female. The current study updates and examines changes in body measurements and…

The task of preparing teachers to use technology in the classroom now extends beyond the walls of the university and into the classrooms of in-service teachers, as many states require technology competency for maintaining teaching credentials.

Relatively little is known about the incidence of declassification among young children who receive preschool special education services or about factors associated with declassification. The Pre-Elementary Education Longitudinal Study (PEELS) follows a nationally representative sample of children who were receiving preschool special education…

The majority of studies investigating the effects of parental behaviour on the child's adjustment have a dimensional approach. We identified the existence of various patterns in parental rearing styles and analysed the relationship between different parenting patterns and behavioural problems in a group of school-aged children. A longitudinal,…

There has been growing concern as to the mental health status of persons with learning disabilities (PWLD). This study examined rates of mental health problems among PWLD aged 15 to 44 years using a large, nationally representative data set. PWLD were more than twice as likely to report high levels of distress, depression, anxiety disorders,…

The Danger Assessment (DA) is an instrument designed to assess the likelihood of lethality or near lethality occurring in a case of intimate partner violence. This article describes the development, psychometric validation, and suggestions for use of the DA. An 11-city study of intimate partner femicide used multivariate analysis to test the…

Working in some capacity is almost considered de rigueur for tertiary students. The reasons for working and the impact this has on both an individual's ability to complete their studies and on their post-study labour market outcomes are only recently receiving attention. Using the 1995 and 1998 cohorts of the Longitudinal Surveys of Australian…
