Embracing transformational leadership: Team values and the impact of leader behavior on team performance.

The authors investigated the relationship between transformational leadership behavior and group performance in 218 financial services teams that were branches of a bank in Hong Kong and the United States. Transformational leadership influenced team performance through the mediating effect of team potency. The effect of transformational leadership on team potency was moderated by team power distance and team collectivism, such that higher power distance teams and more collectivistic teams exhibited stronger positive effects of transformational leadership on team potency. The model was supported by data in both Hong Kong and the United States, which suggests a convergence in how teams function in the East and West and highlights the importance of team values.

小型加氢站网络的成本分析

在2008年之前,上海的燃料电池汽车数量将达到百辆级规模,为了示范运行这些车辆,迫切需要建立一个有若干个加氢站组成的小型网络来提供加氢服务,为此需要确定投资运营成本。本文通过建立氢气运输成本模型(HTCM)和加氢站成本模型(HSCM),以90辆燃料电池轿车和10辆燃料电池公交车为服务对象,对由4种不同类型共5个加氢站组成的小型网络为案例,计算了每个加氢站的投资运行成本、氢气使用成本。结果表明,整个加氢站网络的年均总成本大约为769万元,而氢气的最终使用成本依据不同的供氢方式在30~77元/kg之间。     

考虑电气价因素的压气站运行优化模型研究

针对压气站运行优化模型，引入了两个开关型变量：压气站开关变量和压缩机开关变量：同时还引入了考虑提供单位功率所需的能耗量两个变量。其优点是考虑了压气站越站和站内压缩机停机的情形，而且还直接引入与价格相关的变量，使得模型在运行优化的结果上更能体现某种方案的经济性，这对于管道运行商来说，更具有直观性。     

Category Norms as a Function of Culture and Age: Comparisons of Item Responses to 105 Categories by American and Chinese Adults.

Understanding how aging influences cognition across different cultures has been hindered by a lack of standardized, cross-referenced verbal stimuli. This study introduces a database of such item-level stimuli for both younger and older adults, in China and the United States, and makes 3 distinct contributions. First, the authors specify which item categories generalize across age and/or cultural groups, rigorously quantifying differences among them. Second, they introduce novel, powerful methods to measure between-group differences in freely generated ranked data, the rank-ordered logit model and Hellinger Affinity. Finally, a broad archive of tested, cross-linguistic stimuli is now freely available to researchers: data, similarity measures, and all stimulus materials for 105 categories and 4 culture-by-age groups, comprising over 10,000 fully translated unique item responses.

加油站设置发电机组问题的探讨

针对有些加油站在采用外接电源的同时配备发电机组存在的诸如使加油站安全要求提高、设备投入费用增加、运营管理成本增加、发电机组使用效率低和安全隐患增加等问题，建议本着经济的原则，在缺电少电比较严重的地区或引用外接电源有困难的加油站可另外设置发电机组，对遇偶然性停电的加油站，应采用在市场上临时租赁移动发动机业务或由公司组建自己的移动式发电机组服务部门，以保证加油站应急用电需求。
