Influence of Peer Pressure and Self-Efficacy for Alcohol Self-Regulation on Chinese University Physical Education Students’ Drinking Behaviors

This study examined peer group influence on university student drinking in China and the indirect effects of peer pressure and self-efficacy for alcohol self-regulation. A total of 951 undergraduate university students (first, second and third year) from a university in central China completed questionnaires asking about perceived peer pressures, self-efficacy for alcohol self-regulation, and drinking frequency. Analysis of their answers showed that the drinking frequency among physical education (PE) students was higher than among the comparison group (History students). The PE students perceived greater peer pressure, and had lower self-efficacy for alcohol self-regulation, both of which contributed directly to drinking frequency. Path analysis indicated indirect effects of peer pressure and self-efficacy for alcohol self-regulation on the association between peer group membership and drinking frequency. This suggested that skills training to increase self-efficacy for alcohol self-regulation in culturally-specific settings have the potential to both directly and indirectly lower drinking rates in peer groups with high peer pressure and higher than normal drinking

The personal and contextual contributors to school belongingness among primary school students

School belongingness has gained currency among educators and school health professionals as an important determinant of adolescent health. The current cross-sectional study presents the 15 most significant personal and contextual factors that collectively explain 66.4% (two-thirds) of the variability in 12-year old students' perceptions of belongingness in primary school. The study is part of a larger longitudinal study investigating the factors associated with student adjustment in the transition from primary to secondary school. The study found that girls and students with disabilities had higher school belongingness scores than boys, and their typically developing counterparts respectively; and explained 2.5% of the variability in school belongingness. The majority (47.1% out of 66.4%) of the variability in school belongingness was explained by student personal factors, such as social acceptance, physical appearance competence, coping skills, and social affiliation motivation; followed by parental expectations (3% out of 66.4%), and school-based factors (13.9% out of 66.4%) such as, classroom involvement, task-goal structure, autonomy provision, cultural pluralism, and absence of bullying. Each of the identified contributors of primary school belongingness can be shaped through interventions, system changes, or policy reforms

Preying at the edge of the sea: the nermertine Tetrastemma melanocephalum and its amphipod prey on high intertidal sandflats

In the European Wadden Sea, the nemertine Tetrastemma melanocephalum occurs together with its prey, the amphipod Corophium arenarium in the upper intertidal zone. T. melanocephalum leaves the sediment when the tide has receded and captures C. arenarium in its U-shaped burrow. Highest abundances of T. melanocephalum on the sediment surface were found on summer evenings, two to four hours after high tide, when just a thin film of water was left on the flats. Laboratory Y-maze experiments indicated that gradients of substances produced by C. arenarium in this film of water play a role in tracking the prey. In the field, T. melanocephalum appeared in significantly higher numbers on experimental high density patches of C. arenarium. The amphipod in turn is able to recognize the nemertine. In aquarium experiments significantly more amphipods escaped from the sediment into the water column when the predator was present. In the field, both predator and prey showed a high mobility by drifting in tidal waters. Benthic abundance maxima of T. melanocephalum and C. arenarium usually did not coincide spatially. It is assumed that the nemertines avoid tidal flats that dry out quickly leaving too little time for prey capture. T. melanocephalum is not able to dig into the sediment but lives in burrows of Nereis diversicolor. The abundance of this polychaete was inversely related to C. arenarium, presenting a dilemma for T. melanocephalum: the spatial overlap of food and accommodation was rather small
