Developing a Broadly Applicable Measure of Risk Perception

Decades of research identify risk perception as a largely intuitive and affective construct, in contrast to the more deliberative assessments of probability and consequences that form the foundation of risk assessment. However, a review of the literature reveals that many of the risk perception measures employed in survey research with human subjects are either generic in nature, not capturing any particular affective, probabilistic, or consequential dimension of risk; or focused solely on judgments of probability. The goal of this research was to assess a multidimensional measure of risk perception across multiple hazards to identify a measure that will be broadly useful for assessing perceived risk moving forward. Our results support the idea of risk perception being multidimensional, but largely a function of individual affective reactions to the hazard. We also find that our measure of risk perception holds across multiple types of hazards, ranging from those that are behavioral in nature (e.g., health and safety behaviors), to those that are technological (e.g., pollution), or natural (e.g., extreme weather). We suggest that a general, unidimensional measure of risk may accurately capture one's perception of the severity of the consequences, and the discrete emotions that are felt in response to those potential consequences. However, such a measure is not likely to capture the perceived probability of experiencing the outcomes, nor will it be as useful at understanding one's motivation to take mitigation action.     

集权、分权、利益集团理论与美国公共行政的发展

本文从论述汉密尔顿、杰斐逊和麦迪逊政治思想入手，分析了以集权思想为特征的汉密尔顿＂古典式行政模式＂、以分权思想为特征的杰斐逊＂浪漫式行政模式＂和以利益集团思想为特征的麦迪逊＂新古典式行政模式＂产生的历史条件和原因，并从宏观上考察了３种＂行政模式＂在美国行政的不同发展阶段中的实践和影响。     

脊波导宽频带电磁参数测试技术

针对高损耗介质材料电磁参数的宽频带测试问题,提出了利用脊波导进行测试的新方法,建立了电磁参数测试系统,并采用TRL技术进行了系统校准。该方法仅用3个波段的脊波导即可覆盖2.0～18.0GHz宽频带范围内的电磁参数测试,具有频带宽、体积小、测试精确度高等优点。

见义不为现象的法律救治

见义勇为立法的重要内容之一,就是规定社会和国家对见义勇为者权益的救济和保护负有不可推卸的义务。作者认为对见义勇为者的权益实行法律保护是救治当前道德冷漠现象的一剂良方,是与现实需要紧密结合的法律规范。它的制定与实施又进一步充实了法律的正义精神,是法律价值的全面体现。但在现阶段我国还不具备相应的历史与现实条件用法律强制的手段推行见义勇为的道德行为。     

衍生金融工具的计量研究

衍生金融工具因具有高风险性、时态未来性及品种多样性等特点，其计量问题一直是会计核算的核心和难点。传统的会计计量理论和方法已无法满足其要求。为此，有必要改进现行的会计核算体制，以公允价值取代历史成本对衍生金融工具进行计量，以增强信息披露的力度。     

和谐社会构建中的利益表达与利益协调

我国正处在一个社会转型的时代,利益关系格局也发生了一定的变化,产生了利益分化和重组。在这个利益分化的时代,中国的经济利益关系格局出现了经济利益主体多元化、经济利益来源多样化、经济利益差距扩大化和经济利益关系复杂化等新的特征。对此,我们必须正视问题,应特别注意利益表达机制的构建并进行合理的利益协调,充分发挥市场、政府和利益集团的作用,只有这样才能构建一个和谐的社会。     

谈激发大学生政治理论课的学习兴趣

政治理论课是大学生必修的一门课程,它不仅向学生讲授马克思主义的理论知识,还要帮助学生树立科学的世界观、人生观和价值观。政治理论课的教学质量如何,不仅影响到每个学生的未来,而且关系到国家的前途。所以我们要大力改进课堂教学,用教学的高质量来培养学生的高素质。如今大学生普遍不喜欢上政治理论课,极大地影响该课程的教学效果,更难以实现政治理论课的智育和德育双重功能。我们认为,针对目前大学政治理论课的低效性现状,可以通过激发学生的学习兴趣来提高政治理论课的教学效果。     

Deposit Insurance,Institutions, and Bank Interest Rates

Many recent institutional reforms of the financial system have relied on the introduction of an explicit scheme of deposit insurance. This instrument aims at two main targets, contributing to systemic stability and protecting depositors. However, it may also affect the interest rate spread in the banking system, which can be viewed as an indicator of either inefficiency or market power in this financial segment. This paper provides an empirical investigation of the effect of deposit insurance and other institutional and economic variables on bank interest rates across countries. We find that deposit insurance increases the lending–deposit spread in banking. The main effect seems to arise not from the deposit side though, but from an increase in the lending rate. We interpret this result as evidence of the presence of moral hazard problems related to this instrument. We also find that higher quality of institutions is associated with lower spreads, thus contributing to eroding sources of market power in the banking sector.
