The Application of Sensitivity Analysis on Comprehensive Transportation Evaluation

Comprehensive transportation evaluation objects using multi-objective decision method is a process of choosing the best one from a few objects through calculating, analyzing, and comparing the index system. The result may be different because of the difference of the index weight and index value. Therefore, sensitivity analysis should be one of the necessary parts of the decision-making. It is desired to give the index with higher sensitivity and its varying scope to control the index strictly during the execution process. This paper derives transfer index weight, which changes the rank evaluation order of the projects. Meanwhile, a simple, effective and practical method based on sensitivity district and sensitivity matrix is proposed for the sensitivity analysis of decision-making. As an example, the index sensitivity in decision-making of some provinces comprehensive transportation objects, and their influence on the final decision are discussed.     

Investment opportunities and cash holdings of firms: an empirical study on Korean firms

We find that the cash flow sensitivity of cash holdings of firms whose investment opportunities are lower is significantly higher by examining a panel data of 898 Korean firms for 1999–2014. The cash flow sensitivity of investment is also found to be lower in case of low investment opportunity. Both findings suggest that firms decide to hold cash in response to an increase in cash flow when they do not have a good investment opportunity. Precautionary motive because of financial constraints and uncertainty, and agency problems, however, are not associated with the cash flow sensitivity of cash holdings. These findings imply that it is necessary to develop new investment opportunities to encourage firms to spend more cash in Korea.     

当代农民消费行为研究

本文运用现代消费理论对中国的农民消费行为进行研究,在对模型的数据进行平稳性检验的基础上,建立误差修正模型作为计量模型,认为农民面临的不确定性、农民消费的过度敏感性和农民消费行为的生命周期特征是影响农民消费行为的重要因素.影响农民消费行为的这些因素实际上反映了农村市场化进程的滞后,必须积极推动以市场化为核心的农村制度改革.     

Gender-Based Vicarious Sensitivity to Disempowering Behavior in Organizations: Exploring an Expanded Concept of Hostile Working Environment

The purpose of this study was to explore evidence of gender-based vicarious sensitivity to disempowering behavior in organizations, expanding the concept of hostile working environment beyond the context of sexual harassment. Male and female graduate and undergraduate students viewed 10 video segments of Anita Hill's interview by U.S. senators during the October 1991 confirmation hearings of Supreme Court Justice Nominee, Clarence Thomas. Although no significant relationship was found between the personal attributes of age and ethnicity to perceptions of disempowering behavior, female participants reported seeing significantly more offensive behavior in the video segments than did male participants. The results are discussed in terms of greater female sensitivity to common forms of disempowering behavior in organizations, and having a disparate negative impact and systematically placing women at a disadvantage in today's workforce.

羧甲基壳聚糖/海藻酸钠水凝胶pH值对溶胀行为的影响

以CaCl2为交联剂制备了一系列羧甲基壳聚糖/海藻酸钠水凝胶。研究了羧甲基壳聚糖与海藻酸钠溶液的配比、交联剂的用量以及pH值对水凝胶溶胀率的影响,并分析了不同pH值时水凝胶的红外谱图。结果表明,pH=1.0、3.0时,水凝胶收缩,而pH=5.0、7.4、9.0、13.0时,水凝胶溶胀随pH值增高,其溶胀率增大。当两者配比为1:3,pH 9.0时溶涨率最大。同时,红外谱图证明,水凝胶的pH敏感行为是氨基和羧基基团结构的变化所引起的。
