We compared a matched sample of heterosexual and lesbian, gay, and bisexual (LGB) students on 5 psychosocial adjustment composites, longitudinally across the transitional first year of college. Both LGB and heterosexual students experienced a significant increase in psychological distress over the first semester, along with significant decreases…

The purpose of this study was to use data from the National Longitudinal Transition Study-2 (NLTS2) to (a) conceptually identify and empirically establish student, family, and school constructs; (b) explore the degree to which the constructs can be measured equivalently across disability groups; and (c) examine latent differences (means,…

In this dissertation, an Expectation-Maximization (EM) algorithm is developed and implemented to obtain maximum likelihood estimates of the parameters and the associated standard error estimates characterizing temporal flows for the latent variable time series following stationary vector ARMA processes, as well as the parameters defining the…

Connections between graphical Gaussian models and classical single-factor models are obtained by parameterizing the single-factor model as a graphical Gaussian model. Models are represented by independence graphs, and associations between each manifest variable and the latent factor are measured by factor partial correlations. Power calculations…

This article reviews factor-analytic research on individually administered intelligence tests from a Cattell-Horn-Carroll (CHC) perspective. Although most new and revised tests of intelligence are based, at least in part, on CHC theory, earlier versions generally were not. Our review suggests that whether or not they were based on CHC theory, the…

Social scientists have been studying imagined interactions since the mid-1980s and have measured numerous physiological correlates (Honeycutt, 2010). In this commentary I assess the research reported in Crisp and Turner (May-June 2009) and highlight the underlying mechanisms of imagined interactions that have empirically been laid out across…

This longitudinal study analyzed associations of problem behavior with the attainment of developmental tasks in 133 adolescents with visual impairment and 449 sighted peers. Higher levels of initial problem behavior predicted less progress in the attainment of developmental tasks at the one-year follow-up only in sighted adolescents. This…

This research paper explores the concept of "cost sharing" which became more prominent in Zambia education with the advent of democratic form of governance in 1991. As a way of responding to the ever diminishing tax revenues, government through the education policy of 1996, allowed higher education institutions including public…

We conducted a mixed-methodological study of matriculation issues for African-American students in science. The project compares the experiences of students currently majoring in science (N = 304) with the experiences of those who have succeeded in earning science degrees (N = 307). Using a 57-item Likert scale questionnaire, participants were…

Each year, approximately 1.3 million students fail to graduate from high school. One of the reasons cited for dropping out is a lack of connection to the school environment. One way students can connect to their school is through programs and organizations at their school. While there are a large variety of programs in schools that have the…

This paper examined relationships between students' engagement in community service in different contexts through classes, student organizations, work study, and on their own as well as their development of socially responsible leadership at a large, public, research university in the Upper Midwest. Results from the Multi-Institutional Study of…

The current study examined the associations among clients' perceptions of self- and social stigma for seeking help, session outcomes, and working alliance. Ninety-one clients were treated by 26 therapists, at a large university counseling center. All clients were currently in therapy. We expected that clients' perceptions of self- and social…

Current technological pedagogical content knowledge (TPACK) studies are inclined to treat technology in a general manner, an approach which may not be able to provide adequate guidelines to improve teacher preparation and professional development when teaching with games. This study developed two new questionnaires, namely the Technological…

This paper presents results of a questionnaire focused on investigating students' confidence and behavioral intention in the area of programming, particularly that of structures, problem solving, and programming commands (Conditional--Loop). Responses from 116 1st year students regarding informatics were used. The results indicate that the…

This study designed 1) to develop a multidimensional thinking styles scale based on theory of mental self-government for sixth grade student 2) to investigate quality of the developed scale 3) to study profile of styles of sixth grade student and a relation of profile of styles of student in each dimension and background of gender and grade with…
