A method is presented for generalized canonical correlation analysis of two or more matrices with missing rows. The method is a combination of Carroll's (1968) method and the missing data approach of the OVERALS technique (Van der Burg, 1988). In a simulation study we assess the performance of the method and compare it to an existing procedure…

The standard univariate and multivariate methods are conventionally used to analyze continuous data from groups by trials repeated measures designs, in spite of being extremely sensitive to departures from the multisample sphericity assumption when group sizes are unequal. However, in the last 10 years several authors have offered alternative…

This research brief presents the results of an extensive review of research studies to identify maternal and family antecedents (conditions and characteristics before and during pregnancy) of healthy infant and child outcomes. The researchers identified seven major categories of antecedents associated with a strong start in life: the mother's…

Background: The marked degree of heterogeneity in persons with developmental dyslexia has motivated the investigation of possible subtypes. Attempts have proceeded both from theoretical models of reading and the application of unsupervised learning (clustering) methods. Previous cluster analyses of data obtained from persons with reading…

The main objectives of this article are to determine the prevalence of criminality among a sample of female African American drug users and to examine change in criminality over time, including the correlates associated with this change. Data were collected from 336 adult women who participated in an HIV risk-reduction intervention focused on the…

Although several antecedents of statistics anxiety have been identified, many of these factors are relatively immutable (e.g., gender) and, at best, identify students who are at risk for debilitative levels of statistics anxiety, thereby having only minimal implications for intervention. Furthermore, the few interventions that have been designed…

Recent research indicates that adjudicated female youth have higher rates of mental health problems and histories of trauma exposure and abuse relative to adjudicated male youth. These differences are important for gender-specific assessment, intervention, and management strategies. We replicated a subtyping strategy for adjudicated female youth…

Electrical engineering (EE) curricula in the Gulf Cooperation Council (GCC) region have gone through an evolutionary process, and are now approaching a maturity level. In order to address academic and local industrial needs in a unified way, a need has been felt to investigate EE curricula in a way that highlights theoretical understanding, design…

Most state inmates incarcerated under the jurisdiction of the New Jersey Department of Corrections are driven to crimes by drug abuse. Understanding the factors contributing to addiction is the first step in developing strategies for successful inmate reintegration. This study presents an analysis of inmate addiction and factor association using…

This study examined the effect of improvements in timing/rhythmicity on students' reading achievement. 86 participants completed pre- and post-test measures of reading achievement (i.e., Woodcock-Johnson III, Comprehensive Test of Phonological Processing, Test of Word Reading Efficiency, and Test of Silent Word Reading Fluency). Students in the…

This study used a person-oriented approach to examine links between adolescents' experiences with parents and peers. Cluster analysis classified 361, White, working- and middle-class youth (mean age = 12.16 years) based on mothers' and fathers' reports of parental acceptance and adolescents' reports of perceived peer competence. Three patterns…

Context: Rural communities, often with complex health care issues, have difficulty creating and sustaining an adequate health professional workforce. Purpose: To identify factors associated with rural recruitment and retention of graduates from a variety of health professional programs in the southwestern United States. Methods: A survey…

Self-regulated learners engage in self-generated thoughts, actions, and feelings while pursuing academic goals. The most successful learners use appropriate learning strategies and maintain high levels of motivation. Few studies on the self-regulation of learning have examined individual differences such as gender and ethnicity among college…

In this study we examined the relation between children's social competence and their first-grade classroom environment. Drawing from data from the NICHD Study of Early Child Care and Youth Development, we used cluster analysis to identify 4 types of typical classrooms based on observed classroom emotional and instructional supports. The 4 types…

We investigated preferences for climate change mitigation policies and factors contributing to higher levels of policy support. The sample was comprised of 316 Michigan and Virginia residents, all of whom completed mail surveys. Of the eight policies proposed to reduce the burning of fossil fuels, respondents overwhelmingly indicated they would…
