The future of hydrogen fueling systems for transportation: An application of perspective-based scenario analysis using the analytic hierarchy process

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool.     

Effect of supervisor–subordinate guanxi on supervisory decisions in China: an empirical investigation

As China is becoming an important market and there are a lot of foreign ventures operating there, different lines of research have been providing useful information for foreign ventures to manage effectively in China. In this paper, we discuss one of the critical factors leading to successful management of Chinese subordinates, i.e. building and maintaining good guanxi (i.e., interpersonal connection) with them. We conducted an empirical investigation to illustrate (1) the supervisor-subordinate guanxi concept is different and unique when compared to other similar concepts in the Western literature such as leader-member exchange (LMX) and commitment to supervisor; (2) the supervisor-subordinate guanxi will affect the Chinese supervisor's administrative decisions; (3) guanxi can be measured by concrete behaviour/activities. Data on 189 supervisor-subordinate dyads were collected in the People's Republic of China (PRC). Results indicated that supervisor-subordinate guanxi is a distinct concept from LMX and commitment to supervisor. It also has additional explanatory power over supervisory decisions on promotion and bonus allocation after controlling for performance. Implications for foreign ventures and expatriates are discussed.     

Reformulation and assessment of the inventory approach to urban growth boundaries

Based on the theoretical framework, in this article we demonstrate how Decision Network can be used to formulate the inventory approach to urban growth boundaries (UGBs) as an application of the planning tool to a general case. In particular, in the inventory approach expansions of UGBs are considered as decision situations, land consumptions as problems, and order sizes of UGBs as solutions. We compare the time- and event-driven systems of the inventory control problem based on the decision network framework. The former in the framework is considered as making single, independent decisions in time, whereas the latter as making multiple, linked decisions in time. Our numerical example shows that the event-driven system is more effective than the time-driven system in that the former incurs less total cost than the former in the UGBs context. The implication is that making multiple, linked decisions, as manifested by Decision Network, would yield more benefits, such as lowering the total cost, to the planner than making these decisions independently.

政治系统与法律系统对于技术风险的决策观察

德国社会学家尼古拉斯·卢曼的社会系统论和二阶观察理论所提供的社会建构论框架,有助于我们从技术、时间、知识、决策等维度厘清技术风险形成的复杂社会机制,促进我们对政治系统和法律系统中的技术风险管制活动进行反思性观察。政治系统通过政策性决策活动规划和控制技术风险的努力,本身也会导致决策风险,政治系统因此发展出令规制失灵而被社会遗忘的应对能力;法律系统内部发展出来的风险预防原则,其功能不在于增加社会的安全水平,而是作为一种程序性反应机制,吸收因科学技术后果的不确定性所导致的环境复杂性。

新兴技术社会风险化解的前瞻性治理特征

新兴技术这柄“双刃剑”虽然给国家带来新发展动能,但也同时引发诸多社会风险,如何化解新兴技术社会风险成为新兴技术治理面临的难题。前瞻性治理研究为新兴技术社会风险化解提供了一些思考,但是相关研究较为分散和模糊,相关经验难以奏效。运用文本分析法和层次分析法,聚焦治理主体、过程和结果3个要素,提炼新兴技术社会风险化解的前瞻性治理特征,并在中国情境下检验其适用性。结果表明,公众参与结果纳入既定政策议程、否决权、新兴技术公众参与法律法规等前瞻性特征得到专家一致认同,认为它们是新兴技术社会风险化解的必要条件。研究结论对提高新兴技术社会风险治理绩效具有一定理论启示。     

The relative importance of facial attractiveness and gender in Hong Kong selection decisions

This field experiment found that Hong Kong human resources management specialists were influenced by the attractiveness bias in evaluating short-listed candidates for an entry-level trainee position. Zero order, stepwise and hierarchical regressions showed that perceived attractiveness of the candidates was more related to their work experience and work-related skills than to grade-point average and public examination results. Women candidates were generally preferred over male candidates. Further research is suggested to determine if the influence of attractiveness extends over a wider range of jobs and to measure more precisely the influence of attractiveness in different cultures and for men and women.
