环境保护公众参与及国家文明程度

电影《无极》剧组污染香格里拉的行为一时间弄得沸沸扬扬。这不仅仅是老百姓对公众人物社会责任感的质疑,更是我们这个社会公众环境意识和参与意识有了空前的提高。我认为这也是一个国家文明程度的体现。

Empirical analysis of shared leadership promotion and team creativity: An adaptive leadership perspective

Promoting shared leadership in teams and enhancing team creativity is aided by complementarity between leader and team member characteristics. We integrate insights from social learning theory and dominance complementarity perspective with the team leadership and creativity literature to explore the facilitating role of formal participative leadership for enhancing team creativity indirectly by promoting shared leadership. The relationships among formal participative leadership, shared leadership, and team creativity are bounded by team voice behavior and team creative efficacy. To test our theoretical model, we collected multisource and multiwave survey data from 382 members of 73 teams. Results revealed a significant positive relationship of participative leadership with shared leadership in teams, which in turn was positively associated with team creativity. Team voice behavior and team creative efficacy moderated these relationships, respectively, by strengthening the positive relationships. We discuss the theoretical contributions, practical implications, and future directions of our findings.     

侧向风速作用下聚氨酯泡沫双火源火蔓延研究

为探究环境风作用下逆向双点火源聚氨酯泡沫火蔓延及融合行为,开展多组对照实验并从材料传热机理角度分析侧向风速对火蔓延行为中火羽流形态、质量损失和辐射热流场等特征参数的影响。结果表明:风速与上述参数之间存在非线性关系。环境风效应使火焰被拉长且敷贴于预热区表面,增大预热区面积和热反馈;侧向风速的增加对FPU板材质量损失的影响逐渐弱化,且板材的熔滴率与风速呈正相关;无论侧向风是否存在,两侧逆向火焰融合后均达到整个蔓延过程中的峰值温度;风速的存在限制了火焰温度与辐射热通量峰值,也缩短了温度和辐射峰值出现的时间。     

农村变电站生活污水处理现状与探讨

我国大部分变电站位于农村地区,因无接入城市污水管网条件,农村变电站生活污水需就地处理后达标排放。变电站生活污水存在水量少、时变化系数大等特点,现有处理工艺不能正常运行或无法达标排放。本文借鉴农村生活污水处理技术,提出了生物组合法处理对策,可为变电站生活污水处理提供参考。
