This article presents an in-class Monte Carlo demonstration, designed to demonstrate to students the implications of multicollinearity in a multiple regression study. In the demonstration, students already familiar with multiple regression concepts are presented with a scenario in which the "true" relationship between the response and…

The research reported in this paper explores which variables predict native and non-native speaking teachers' perception of fluency and distinguish fluent from non-fluent L2 learners. In addition to traditional measures of the quality of students' output such as accuracy and lexical diversity, we investigated speech samples collected from 16…

Stephenson, Belesis, and Balliet (2005) urge that future research on college student suicide should not continue its historical emphasis on completed suicide nor on the contrast between students and non-students. But their paper does not provide an adequately complete and accurate summary of our present knowledge of completed student suicide. This…

Recent studies on student learning in higher education have paid attention to the relationships between characteristics of the learning environment and students' study orientations and study success. The purpose of the present paper is to examine these relationships in university level engineering education. The data were collected from…

This study examined the relative contributions of phonological awareness, orthographic pattern recognition, and rapid letter naming to fluent word and connected-text reading within a dyslexic sample of 123 children in second and third grades. Participants were assessed on a variety of fluency measures and reading subskills. Correlations and…

This article describes the word reading skills in English and Spanish for a sample of 244 Spanish-speaking, English-learning (hence, bilingual) students in first grade and presents a predictive model for English word reading skills. The children in the study were assessed at the end of kindergarten and first grade, respectively. Data were gathered…

This study examined the influence of mentor's status (supervisor vs. non-supervisor) and gender similarity (homogeneous vs. diversified) of mentor-protege dyads on protege's perception of mentoring functions and outcomes. We collected and analyzed data from 217 mentor-protege dyads comprised of working professionals from a variety of industries.…

Using a sample of White and Native American high school students, the authors provide a test of (a) self-control theory's invariance thesis and (b) native traditionalism as an explanation of Native American substance use. Self-control significantly influenced all forms of substance use when controlling for race and in race-specific analyses.…

The purpose of this study is to assess personal and interpersonal predictors of college adjustment among a sample of 190 first-year Hispanic students. Specifically, we examined the extent to which personal factors such as self-esteem, acculturation, and ethnic identity and interpersonal factors such as parental education and parental attachment…

This 3-year longitudinal study examined how motivational tendencies, that is, task orientation and social dependence orientation, as well as cognitive-linguistic prerequisites of reading and math skills (i.e., phonological awareness, rapid naming, oral language comprehension skills, number sequence and basic arithmetic skills) measured in…

In this study, the authors tested a social ecological model of illness management in high-risk, urban adolescents with Type 1 diabetes. It was hypothesized that management behaviors would be associated with individual adolescent characteristics as well as family, peer, and provider relationships. Questionnaires were collected from 96 adolescents…

Although maladaptive and compulsive behaviors are increasingly well-described in young persons with Prader-Willi syndrome, it is unclear how these problems manifest in older adults with this syndrome. In Part I, I compared maladaptive and compulsive behaviors in 45 older adults with Prader-Willi syndrome (ages 30 to 50 years) to 195 children,…

We report on a 20-year follow-up of 30 children with developmental delays identified at age 3. Our purpose was to assess the relationship of early indicators of delay to cognitive and personal-social status in young adulthood. Predictors were Developmental and Personal-Social factors derived from standardized tests and parent questionnaires…

This study examined sex differences in risk factors associated with adolescent depression in a large sample of boys and girls. Moderation and mediation explanatory models of the sex difference in likelihood of depression were examined. Findings indicate that the factors associated with depression in adolescent boys and girls are quite similar. All…

Using survey data collected from households living in the Brisbane-South East Queensland region, a rapidly growing metropolis in Australia, path analysis is used to test links between urban residents' assessment of various urban attributes and their level of satisfaction in three urban domains--housing, neighbourhood or local area, and the wider…
