Due to its centralized content-sharing features, a project portfolio management (PPM) portal enables vertical, as well as horizontal, electronic exchanges between project professionals. Such exchanges, if effective, may deliver an individual impact through improved project performance. Effectiveness engenders use and satisfaction, reflecting the…

Academic buoyancy has been defined as a capacity to overcome setbacks, challenges, and difficulties that are part of everyday academic life. Academic resilience has been defined as a capacity to overcome acute and/or chronic adversity that is seen as a major threat to a student's educational development. This study is the first to examine the…

Exploratory structural equation modeling (SEM) was applied to a multiple indicator (26 individual symptom ratings) by multitrait (ADHD-IN, ADHD-HI and ODD factors) by multiple source (mothers, fathers and teachers) model to test the invariance, convergent and discriminant validity of the Child and Adolescent Disruptive Behavior Inventory with 872…

A crucial issue in the European Union (EU) is which policies should be regulated by EU and which ones by national governments. Given this situation it is interesting to study the citizens' preference for the level of political decision making. The interest of the paper is mainly empirical, which consists in the creation of a measure for…

Throughout much of the social and behavioral sciences, latent growth modeling (latent curve analysis) has become an important tool for understanding individuals' longitudinal change. Although nonlinear variations of latent growth models appear in the methodological and applied literature, a notable exclusion is the treatment of growth following…

This research investigates the merits of the "social causation" and "health selection" explanations for associations between socioeconomic status and self-reported overall health, musculoskeletal health and depression. Using data that include information about individuals' SES and health from childhood through late adulthood, I employ structural…

We discuss the identification, estimation, and testing of structural equation models that have causal indicators. We first provide 2 rules of identification that are particularly helpful in models with causal indicators--the 2C emitted paths rule and the exogenous X rule. We demonstrate how these rules can help us distinguish identified from…

Despite substantial evidence that women suffer from depression at twice the rate of men, the etiology for this difference remains unclear. Prior to puberty, the difference in depression is negligible; however, when adolescence begins, a precipitous rise in female depression occurs that persists across the lifespan. While no definitive biological…

The purpose of the present study was to investigate the variation of influencing factors of e-learning continuance intention for different degrees of participation and to examine moderating effects of degrees of participation on influencing factors of e-learning continuance intention. Participants included 670 learners from an adult professional…

Distance education learning environments provide tremendous convenience and flexibility, allowing busy, mobile adult learners to engage in education while coping with their limited resources in terms of time, energy and finances. Following a student-centered approach this study investigates adult students' subjective perceptions while using…

An exploratory study of undergraduate students enrolled in marketing courses at a Southeastern regional university was conducted to determine the motivations and characteristics of marketing students who plan to be online learners and examined for differences between those who have taken and those who have not taken online classes. An online…

What makes a student feel vital and energetic? Using the self-determination framework, we analyzed how the behavior and feelings of students depend on social factors such as the teachers' attitudes. The goal of the study was to test an integrated sequence over a semester in which teacher's autonomy support acts as a predictor of autonomy, which,…

The present study explored data from a survey of students' performance in English at the end of compulsory school in 6 European countries. The aim was to gain deeper knowledge of the internal structure of the test and to discuss similarities and differences between the different settings regarding patterns in language proficiency. The analyses,…

To reduce the high incidence of cervical cancer among Latinas in the United States it is important to understand factors that predict screening behavior. The aim of this study was to test the utility of theory of planned behavior in predicting cervical cancer screening among a group of Latinas. A sample of Latinas (N = 614) completed a baseline…

This study was an initial attempt to operationalise Moore's transactional distance theory by developing and validating an instrument measuring the related constructs: dialogue, structure, learner autonomy and transactional distance. Data were collected from 227 online students and analysed through an exploratory factor analysis. Results suggest…
