The paper describes some challenges andpitfalls in the derivation of the executable model from the DoDAF products, especially when temporal and queuing issues are involved. The presence of ambiguities or lack of information in the architecture description may result in different modeling assumptions for the executable model being constructed. These assumptions – untraceable to the information c...

Associations between the satisfaction of basic psychological needs of autonomy, competence, and relatedness with current suicidal ideation and risk for suicidal behavior were examined. Two logistic regressions were conducted with a cross-sectional database of 440 university students to examine the association of need satisfaction with suicidal ideation and risk for suicidal behavior, while cont...

To explore this process in more detail, this study followed a longitudinal sample of 4,907 children and examined demographic factors associated with exposure to high-aggression classrooms, including school cont...

We estimate a structural model of individual smoking behaviour emphasizing the role of individual risk belief on smoking choices. Our model consists of five equations: two selection equations for initiation and cessation decisions, and three switching outcome regressions for nonsmokers, ex-smokers, and current smokers. The presence of significant self-selectivity implies that the health effects...

Recent health campaigns on college campuses have used a social norms approach, which suggests that one's perceptions of others' attitudes and behaviors are the key components in attitude and behavior change. However, the efficacy of social norms campaigns has been mixed. This study was conducted to assess the relationships among sociodemographics, normative perceptions, and individual attitudes...

INTRODUCTION Age-disparate sex has long been considered a factor that increases HIV risk for young women in South Africa. However, recent studies from specific regions in South Africa have found conflicting evidence. Few studies have assessed the association between age-disparate partnerships (those involving an age gap of 5 years or more) and HIV risk at the national level. This study investig...

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting, family dysfunction and/or maternal depression sympto...
