A major goal of the manufacturing industry is increasing product quality. The quality of a product is strongly associated with the condition of the cutting tool that produced it. Catching poor tool conditions early in the production will help reduce defects. However, with current CNC technology, manufacturers still rely mainly on the operator's…

Objective: To investigate abnormalities in the structural integrity of brain white matter as suggested by diffusion tensor imaging in adolescents with early-onset schizophrenia (onset of psychosis by age 18). Method: Twenty-six patients with schizophrenia and 34 age- and gender-matched healthy volunteers received diffusion tensor imaging and…

This longitudinal study examined the relative impact of major variables for predicting adjustment (in terms of both grief and depression) among bereaved parents following the death of their child. Couples (N = 219) participated 6, 13, and 20 months postloss. Use of multilevel regression analyses enabled assessment of the impact of several…

Questionnaires for measuring patients' feelings or beliefs are commonly used in clinical settings for diagnostic purposes, clinical decision making, or treatment evaluation. Raw scores of a patient can be evaluated by comparing them with norms based on a reference population. Using the Pain Cognition List (PCL-2003) as an example, this article…

The purpose of this study was to increase the knowledge base of adolescent substance use by examining the influences of risk and protective factors for specific substance use, namely alcohol, cigarettes, and marijuana. Participants included 271 adolescents and their primary caregivers referred for mental health services across North Carolina. A…

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…
