In developed countries, obesity tends to be associated with worse labor market outcomes. One possible reason is that obesity leads to less human capital formation early in life. This paper investigates the association between obesity and the developmental functioning of children at younger ages (2-4 years) than ever previously examined. Data from…

The present study sought to examine the relationship between teacher quality and student achievement in public elementary schools in a community district school of the New York City.

Unlike traditional interventions, Internet interventions allow for objective tracking and examination of the usage of program components. Student Bodies (SB), an online eating disorder (ED) prevention program, significantly reduced ED attitudes/behaviors in college-aged women with high body image concerns, and reduced the development of EDs in…

In recent years, tertiary institutions in developed countries have made extensive use of Course Management Systems (CMSs), software packages designed to help educators create online learning communities. To date, however, such packages have been little used in higher education institutions (HEIs) in China. In this article, we describe the…

The sample included 1,047 youth (51% female and 49% male and 67% African American and 33% European American). We used analysis of…

This substudy in the evaluation design of the Math and Science Partnership (MSP) Program Evaluation investigates changes in student mathematics and science achievement across three school years, 2002-03, 2003-04, and 2004-05, for MSP-related schools using Management Information System data with the Annual K-12 District Survey. First, changes in…

This study was designed to theoretically articulate and empirically assess the role of computer scaffolds.

Bridging the areas of political-economic sociology, the sociology of agriculture and environmental sociology, this study tests two hypotheses derived from a refined theory of foreign investment dependence. The hypotheses state that pesticide and fertilizer use intensity in less-developed countries are both positively associated with foreign…

Validity data are presented for a new measure of threat appraisals in response to community violence. Adolescents (N = 358; 45% male; 91% African American, M = 12.10 years, SD = 1.63) and their maternal caregivers participated in two waves of a longitudinal interview study focused on the consequences of exposure to community violence. Structural…

The application of scientific tools to analyse the use of Internet-based e-learning tools in academic settings is in general an ignored area. E-learning tools are actually an emergent topic as a result of the new ideas introduced by the European Higher Education Area. Lifelong learning, or the promotion of student initiative, is the new paradigm…

Background: There is uncertainty about the extent to which mildly sub-optimal perinatal characteristics among individuals born near-term (greater than 33 weeks of gestation) are associated with various subsequent childhood problems, including antisocial behavior. There is even more uncertainty about whether the pathway to antisocial behavior…

Patriot High School (PHS) adopted a remediation strategy to help its 10th-grade students at risk of failing the Math portion of MCAS, the state's end of year competency exam. The centerpiece of that strategy was a computer-based instructional (CBI) course. PHS used a commercially available CBI product to align the course content with the…
