This study hypothesized a multilevel model to examine the contextual effects of gender norms, exposure to health-related radio programs, interpersonal communication, and social capital on family planning behavior in Uganda. The results of hierarchical linear modeling showed that all of the four variables were significant predictors of family planning behavior. The authors found that gender norms as a contextual factor significantly interacted with the individual-level perceived benefit. The significant cross-level interaction effect was also observed between individuals' interpersonal communication and contextual variation in listening to a health-related radio program. Practical implications for family planning communication campaigns are discussed.

Persistence is an important part of student success—both in and out of school. To enhance persistence, we first need to assess it accurately. Digital games can be used as vehicles for measuring and enhancing persistence. The purpose of this study is to test the effects of (a) game-level characteristics (i.e., game mechanics and conceptual difficulty), and (b) student-related characteristics (e.g., students’ incoming knowledge and gender) on persistence in a game called Physics Playground. The participants in this study were 137, eighth and ninth-grade students from a K-12 school in Florida. We used a Hierarchical Linear Modeling Approach (HLM) to analyze the data. The major findings are (1) the degree of difficulty relating to both the physics concepts and game mechanics of each game problem are significant predictors of persistence, with the former being more effective than the latter in predicting students’ persistence, and (2) the number of gold and silver trophies students attained in the game were the only significant student-level predictors of persistence. We conclude by discussing the findings, the implications, limitations, and future research related to this study.

Abstract. The present study proposed that, unlike prior leader–member exchange (LMX) research which often implicitly assumed that each leader develops equal-quality relationships with their supervisors (leader’s LMX; LLX), every leader develops different relationships with their supervisors and, in turn, receive different amounts of resources. Moreover, these differentiated relationships with superiors will influence how leader–member relationship quality affects team members’ voice and creativity. We adopted a multi-temporal (three wave) and multi-source (leaders and employees) research design. Hypotheses were tested on a sample of 227 bank employees working in 52 departments. Results of the hierarchical linear modeling (HLM) analysis showed that LLX moderates the relationship between LMX and team members’ voice behavior and creative performance. Strengths, limitations, practical implications, and directions for future research are discussed.
