Risk,affect, and policy support: public perception of air pollution in China

Air pollution is a critical environmental problem that has spurred great public concern in China. This study examines how issue salience, environmental value, risk perception, and affective response influence information seeking, objective knowledge, and policy support related to this issue. The recent release of a controversial environmental documentary on Chinese social media, Under the Dome, also prompted us to explore the impact of exposure to this documentary on Chinese social media users’ information seeking and policy support related to air pollution. Results showed that risk perception and negative affect influenced information seeking and policy support both directly and indirectly. Also, exposure to the documentary moderated the effects of key variables on information seeking and policy support. However, contrary to our expectations, no significant relationship was found between information seeking and objective knowledge. Theoretical and practical implications of these findings were discussed.     

School context and instructional capacity: A comparative study of professional learning communities in rural and urban schools in China

This study examines the teaching gap between rural and urban schools in China from the perspective of teacher professional learning communities (PLCs). Drawing on in-depth interviews with 36 primary school teachers, the study finds striking disparities between rural and urban schools in the working of Teaching and Research Groups (TRGs). These disparities in TRGs result in divergent patterns of instructional capacity building in rural and urban schools. The evidence shows that teaching and teachers are strongly shaped by the school organizational context. It suggests that strengthening school-wide PLCs is an important way of narrowing the rural-urban teaching and learning gaps.     

基于STAR-CCM+的汽车挡风玻璃除霜性能提升的仿真分析与研究

采用计算流体动力学的方法,利用STAR-CCM+软件对某一车型挡风玻璃除霜性能进行数值模拟分析。通过对出风口格栅进行调整,改变了暖风气流与挡风玻璃之间碰撞角的大小与碰撞点的位置,优化了挡风玻璃表面暖风气流的分布,提升了除霜性能,为汽车除霜风道的设计和改善车辆除霜性能提供了参考。
