There are usually limited user evaluation of resources on a recommender system, which caused an extremely sparse user rating matrix, and this greatly reduce the accuracy of personalized recommendation, especially for new users or new items. This paper presents a recommendation method based on rating prediction using causal association rules.…

Organizational and applied sciences have long struggled with improving causal inference in quasi-experiments. We introduce organizational researchers to propensity scoring, a statistical technique that has become popular in other applied sciences as a means for improving internal validity. Propensity scoring statistically models how individuals in…

This study examined the student and high school contextual factors associated with high school students' enrollment in Hispanic-Serving Institutions (HSIs). The authors drew on a conceptual framework of college choice involving the concepts of multiple capitals and individual and organizational habitus to examine the postsecondary trajectories of…

"Theory as Method: Small Theories of Treatments," by Mark W. Lipsey, is one of the most influential and highly cited articles to appear in "New Directions for Evaluation." It articulated an approach in which methods for studying causation depend, in large part, on what is known about the theory underlying the program. Lipsey discussed the benefits…

The standard approach guiding research on the relationship between categories and causality views categories as reflecting causal relations in the world. We provide evidence that the opposite direction also holds: categories that have been acquired in previous learning contexts may influence subsequent causal learning. In three experiments we show…

This study compared the strength of competing causal models in explaining the relationship between perceived support, enacted support, and social anxiety in adolescents. The social causation hypothesis postulates that social support causes social anxiety, whereas the social selection hypothesis postulates that social anxiety causes social support.…

This study examines the effectiveness of multiple methods of soliciting attributions. The Attributional Style Questionnaire, specific attributions, and causal dimensions are used to predict the grades and feelings of frustration of college algebra students. The results show that, contrary to current theoretical work, both specific attributions and…

The relationship between academic self-concept and achievement was examined longitudinally for 46 children at ages 8 and 10. A bidirectional relationship operated between self-concept and achievement. Success attributions to ability were positively related to self-concept and achievement but were not a direct predictor of achievement. (SLD)

Student socioeconomic status (SES) and the perceptions of students' and teachers' expectations and attributions of responsibility for learning and their relationships to achievement were studied using linear structural equation modeling. Two models were developed and tested. One model included student expectations and attributions of…
