Using data from the 2003 Ontario Student Drug Use Survey (Centre for Addiction and Mental Health, Toronto), the relationships between bullying and smoking in adolescents were examined. A representative sample of 3314 grade 7-12 students was included in the analysis. Models were adjusted for confounders identified in the current literature.…

The relationship between nutritional status and intellectual capacity in 6-year-old children was investigated in 83 subjects of medium-high socio-economic status, without any apparent risk of malnutrition and normal or high intellectual capacity. Nutritional status was evaluated by measuring food consumption, anthropometrical measurements and…

As an empirical study based on multiple linear regression analysis of the investigation data, this paper studies the communication between teachers and students in universities. It reveals that the interaction between university teachers and students promotes the personal development of college students. For some reason, however, a rather low…

As a result of the increasing number of nontraditional students in Nigerian universities and the consequences associated with combining multiple roles, this study is designed to examine the relationship among nontraditional students with respect to workload, social support, and work-school conflict. Using a cross-sectional survey, data are…

The problem of fitting a surge function to a set of data such as that for a drug response curve is considered. A variety of different techniques are applied, including using some fundamental ideas from calculus, the use of a CAS package, and the use of Excel's regression features for fitting a multivariate linear function to a set of transformed…

In early intervention, researchers often are interested in interpretation aids that can help determine the relative importance of variables when multiple regression models are used, and that facilitate deeper insight into prediction dynamics. Commonality analysis is one approach for helping researchers understand the contributions independent or…

Context: Hospitalization due to ambulatory care sensitive conditions (ACSCs) is often used as an indicator for measuring access to primary care. Rural health clinics (RHCs) provide basic primary care services for rural residents in health professional shortage areas (HPSAs). The relationship between RHCs and ACSCs is unclear. Purpose: The purpose…

The current study examined the relations between two aspects of emotional competence--emotion knowledge and emotion expression, and children's attentional competence during one school year. Participants were 263 first- and second-grade students at two rural elementary schools. A multiple regression analysis showed that emotion knowledge predicted…

This study examined the relationship between achievement goals and social goals and explored how students' achievement goals and social goals might affect their reported persistence and effort expended toward physical education in high school settings. Participants were 544 students from two high schools in the southwest U.S. Multiple regression…

Adolescent boys (n = 269) were assessed for levels of several risky behaviors related to the pursuit of muscularity, including substance use (anabolic steroids, prohormones, and ephedrine) dieting to gain weight, and symptoms of muscle dysmorphia (MD). The association between these behaviors and a variety of putative biological, psychological, and…

Purpose: Within the framework of learning in organizations, the concept of career-related continuous learning (CRCL) has gained increasing attention from the research community. The purpose of the present study is to explore the combined effect of job- and career-related variables on formal CRCL activities. Design/methodology/approach: The study…

Despite the importance of job satisfaction, little research exists about this factor as it relates to teachers working in a school reform environment. This study addressed teacher characteristics, job dimensions, and work-related psychological states that predict public school teacher job satisfaction in a school reform state. Teachers (N = 578)…

This paper examines the relation between computer use in diverse learning contexts and math achievement, and the gender and ethnicity-based differences in that relation. The study selected learner centeredness as a meaningful pedagogy in using computers because of its importance in technology-based learning. Along with the emerging notion of the…

This paper reports on a study conducted on the National Assessment of Educational Progress (NAEP) 2005 database. The purpose of the study was to examine predictors of student achievement using middle school mathematics teacher professional development items as criterion variables, such as the number of mathematics courses taken, the number of…

In 1990 the Congress of the United States passed Public Law 101-476, The Individuals with Disabilities Education Act (IDEA). This law mandated that students with disabilities be educated in, what this act calls, the Least Restrictive Environment (LRE). Educating students with disabilities in the LRE is also known as inclusion and the terms may be…
