Patterns of current psychotropic medication use among 5,181 children with autism spectrum disorders (ASD) enrolled in a Web-based registry were examined. Overall, 35% used at least one psychotropic medication, most commonly stimulants, neuroleptics, and/or antidepressants. Those who were uninsured or exclusively privately insured were less likely…

This article is an investigation into why U.S. states have enacted, banned, or continued with the status quo regarding in-state tuition policies for unauthorized youth. Using data from multiple government and nonprofit sources, a series of multinomial logistic regressions are estimated to explain the determinants of state behavior across the…

Objectives: Adolescents often experience different types of victimization across a specified period of time in different situations. These multiple victimization experiences can have a number of deleterious effects on psychosocial well-being. To expand on research gathered primarily from US samples, the current study estimated the prevalence of…

Background/Context: A main objective of the Equality of Educational Opportunity Survey (EEOS), conducted in 1965, was to document the lack of availability of equal educational opportunities for minority students in public schools. Another equally important objective was to reveal specific inequalities in facilities and resources available to…

This study examined what kinds of groups can be identified according to students' task-values across four subject domains (languages, math and science, social sciences, practical subjects) and the related gender differences using a person-centered approach. Latent class analysis was applied to classify 638 students (mean age = 15) into four…

Early resistance theorists analyzed working class students' oppositional behavior at a time of high availability of viable jobs in manufacturing. They argued that oppositional behavior constituted a rejection of middle class culture motivated by an implicit understanding of the myth of meritocracy. But times have changed. This paper seeks to…

The goal of this study is to investigate the relationship between the preferred learning styles of professional pharmacy students and their performance/success in a hybrid PharmD pharmacy program making extensive use of online content. Consequently, the study will look for early detection factors which can impact the performance of the student…

The Meyerhoff Scholarship Program, which celebrated its 20th year in 2008, is considered a successful intervention program for increasing the number of underrepresented minorities who earn Ph.D.s or M.D./Ph.D.s and pursue research careers in science, technology, engineering, and mathematics (STEM). This article examines the relationship between…

Differential item functioning (DIF) analysis is a statistical technique used for ensuring the equity and fairness of educational assessments. This study formulates a new DIF analysis method using the information similarity index (ISI). ISI compares item information functions when data fits the Rasch model. Through simulations and an international…

The authors examined internal representations of conditional strategies for a situation of object conflict in 849 adolescents and young adults between the ages of 11 and 19 years. To examine participants' expectations of strategy use, the authors developed questionnaires that depicted a variety of contexts in which 2 people wanted an object that…

Word-level reading and spelling skills support reading comprehension and writing composition. Accurate and fluent word-level reading and spelling are facilitated when individuals have clear mental orthographic representations (MOR) that permit them to quickly recognize and recall the visual representation of a word, freeing up memory and…

The authors identify 2 major types of statistical data from which semantic representations can be learned. These are denoted as "experiential data" and "distributional data". Experiential data are derived by way of experience with the physical world and comprise the sensory-motor data obtained through sense receptors. Distributional data, by…

In this study, students' conceptual difficulties about some basic concepts in quantum mechanics like one-dimensional potential well problems and probability density of tunneling particles were identified. For this aim, a multiple choice instrument named Quantum Mechanics Conceptual Test has been developed by one of the researchers of this study…

Verbal and visuospatial abilities are typically subserved by different cerebral hemispheres: the left hemisphere for the former and the right hemisphere for the latter. However little is known of the origin of this division of function. Causal theories propose that functional asymmetry is an obligatory pattern of organisation, while statistical…

This article examines student departure from university, based on data from a survey of undergraduate university students in Norway conducted in 2005. The survey maps students' progression through higher education, and the analysis focuses on the different types of departure and their causes. More than 50% of all university students left the…
