特种Nafion溶液制备及其在PEMFC中的应用研究

Nafion溶液在燃料电池、电极修饰、电化学分析、电化学催化等领域具有广泛用途。采用特种高沸点溶剂,获得了溶铸性能优良Nafion的溶液。比较溶铸Nafion膜与原始Nafion膜的IR光谱可以看出,Nafion溶液制备方法未对Nafion膜的化学组成与分子结构产生影响,但溶铸膜的分子排列更加规整有序。将该溶液在PEMFC中应用,其性能优于目前的商品水-醇体系Nafion溶液。

嘉陵江洪化元年洪水问题

在四川长江干流及其支流嘉陵江流域曾发现多处“洪化元年洪水”岩刻，有学者据此认定该年嘉陵江流域发生过特大洪水。此文以为，洪化元年应为1679年，即康熙十八年，该年嘉陵江流域没有发生过特大洪水。     

创业投资的治理作用：基于代理成本视角的实证分析

选取2004年至2012年中国沪、深两市首次公开发行上市的1 216家公司作为研究对象,采用相关分析、多元回归分析和工具变量等多种统计分析方法,从代理成本视角探讨创业投资对中国上市公司的治理作用。从总体上检验创业投资参与对中国上市公司代理成本的影响,进一步检验创业投资的参与程度和背景特征是否影响其治理作用的发挥。研究结果表明,有创业投资机构参与的上市公司,其代理成本显著低于无创业投资机构参与的上市公司;创业投资的参与程度越深,即创业投资机构家数越多、持股比例越高、投资期限越长,上市公司的代理成本就越低;与本土背景的创业投资机构相比,外资背景的创业投资机构更能降低上市公司的代理成本。研究结论对上市公司、创业投资机构和政策制定者具有重要借鉴意义和参考价值。     

The Effect of Gender Context on Children's Social Behavior in a Limited Resource Situation: An Observational Study

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty‐six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed‐sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same‐sex groups, and least successful in mixed‐sex groups. Conversely, boys were least successful in same‐sex groups and most successful in mixed‐sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same‐sex girl groups were inequitable but efficient whereas same‐sex boy groups were more equitable than mixed groups but inefficient compared to same‐sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.

Effects of exposure to occupational violence and the mediating impact of fear

This paper examines the consequences of exposure to work-related violence and in particular, focuses upon the role of fear (of violence) as a mediating variable. The sample comprises UK public house licensees-individuals who manage public houses and hold the licence permitting the sale of alcoholic drinks on the premises. Questionnaires were sent to 479 licensees and a response rate of 51% was achieved. Each questionnaire measured exposure to a range of violent assaults, fear of violence, general well-being, job satisfaction and organizational commitment. Based upon a final sample of 242 pub licensees, regression analyses showed that as the severity of the violence to which licensees were exposed increased, so fear of becoming a victim and symptoms of impaired well-being increased, while job satisfaction and organizational commitment decreased. Hierarchical analyses showed that fear of violence fully mediated the negative impact of exposure upon each of these other variables. It is argued that the management of fear appraisals should be integrated into organizational responses to work-place violence.
