一种分析作用条件与作用效果关系的非参数方法

针对数据平均化处理方法无法观察指标个性差异的不足,给出了一种分析作用条件与综合作用效果关系的非参数方法(Con-Eff),并根据以下3种情况构造了相应的数学模型:①所有观察指标越大越好;②所有观察指标越小越好;③一部分观察指标越大越好,另一部分观察指标越小越好。然后,对模型的含义、模型性质以及模型的求解方法进行了探讨。最后,探讨了该方法在高等学校人力资源管理中的应用。     

Models for measuring and benchmarking olympics achievements

As demonstrated in several recent studies, data envelopment analysis (DEA) is a useful tool for evaluating and comparing the performance of nations competing in the Olympic Games. Assurance regions (ARs) have been used to further refine the DEA results. These AR DEA models assume that ARs apply uniformly across all nations. Such models can have shortcomings in the sense that different nations may impose different ARs, as nations may value gold, silver, and bronze medals differently. This paper extends previous DEA studies by incorporating multiple sets of nation-specific ARs into the DEA. By doing so, we establish fair models for measuring and benchmarking the performance of nations at six summer Olympic Games.     

中国省级政府的财政支出效率研究——基于DEA方法分析

利用数据包络分析方法实证研究了2001年和2006年中国30个省级政府的财政支出效率。结果表明,中国省级政府的财政支出效率总体上有进一步提升的空间;非参数检验方法证明了财政支出效率在东部、中部和西部地区之间存在显著差异性。各省级政府应该保持适当的财政支出规模,不断优化财政支出结构,提高财政资金的使用效率;中央政府的转移支付应适当向中西部不发达省份倾斜,推行区域均衡发展战略。     

基于合作性学习的《电路分析》课程改革的研究与实践

《电路分析》课程作为电气信息类专业的主要专业基础课程,对其教学内容、教学方法和手段的改革与探索一直是电路教学的重点．本文介绍课程采用合作性学习的教学改革的一些经验,采用大班授课,小班讨论的教学模式,提高教学互动性,发挥学生学习的自主性．把“以教为主”的教学模式转变为“以学为主”的教学模式,充分调动教与学两方面的积极性,提高教学效率和教学质量,形成了课程特色,获得了较好的教学效果．     

College Students' Money Beliefs and Behaviors: An Asian Perspective

The multidimensionality of money was investigated, using exploratory factor analysis (EFA). The respondents, 290 college students from Korea, Japan, and the United States, were administered a survey, which included socio-demographic questions, and Furnham's (1984) Money Beliefs and Behaviors (MBBS) Scale. Through a series of principal components analyses, a three-factor model with 10 MBBS items was identified. The three factors, Power, Security, and Financial Modesty accounted for 53.6% of the variance. The findings have implications for college students and financial management practitioners.     

城市地价动态监测中有关问题探讨

在对我国已有城市地价动态监测工作评析的基础上,介绍了地价及其动态监测系统,提出城市地价动态监测体系是一个由点、线、面组成的网络系统。利用已构建的城市地价动态监测体系对西安市城区地价变化进行监测,并对监测结果进行地价的空间变化分析、时间变化分析及相关变化分析。最后指出城市地价动态监测体系的应用领域。     

城市倾向的经济政策对于城乡居民收入差距的有效性评价———基于 DEA 和 CCR 模型的面板数据分析

中国在追求经济增长的同时漠视了城乡居民收入不平等问题.长期以来,由于居民收入差距持续扩大,中国政府不断调整经济政策,以期缩小城乡收入差距.而地方政府为了经济增长维持着城市倾向的经济政策,忽视了农村经济的发展,导致了城乡收入差距不断扩大.通过对31个省市的外国直接投资、出口贸易额、农林水支出、城乡社区事务支出、医疗卫生、教育支出、科学支出、文体支出、城乡居民收入差距(城镇人均可支配收入与农村人均纯收入差)数据进行实证分析,构建了反映政策有效性的指标体系,运用数据包络分析对1999—2010年间省级面板数据进行了有效性分析.结果显示,这12年来,中国持续扩大的城乡收入差距与城市倾向的经济政策有关     

从郭店楚简和马王堆帛书论“晚书”的真伪

从宋以来就有学考定今传《古尚书》25篇“晚书”乃后人所编造,近年出土的简帛佚籍马王堆帛书与郭店楚简中相关篇章的内容,恰可证实此说。     

Assessing the Performance of a Classification‐Based Vulnerability Analysis Model

In this article, a classification model based on the majority rule sorting (MR‐Sort) method is employed to evaluate the vulnerability of safety‐critical systems with respect to malevolent intentional acts. The model is built on the basis of a (limited‐size) set of data representing (a priori known) vulnerability classification examples. The empirical construction of the classification model introduces a source of uncertainty into the vulnerability analysis process: a quantitative assessment of the performance of the classification model (in terms of accuracy and confidence in the assignments) is thus in order. Three different app oaches are here considered to this aim: (i) a model–retrieval‐based approach, (ii) the bootstrap method, and (iii) the leave‐one‐out cross‐validation technique. The analyses are presented with reference to an exemplificative case study involving the vulnerability assessment of nuclear power plants.     

金融产品创新:理论、约束和策略

在一个分工演进的分析框架中,可以证明金融产品对资源配置至关重要,产品创新可以增加金融交易配置资源的迂回度,进而提高配置效率。以供给导向为特点的金融产品创新模式不能满足金融开放的需求,表现为金融产品创新缺乏必要的制度空间。金融产品创新需要突破制度约束,建立以市场需求为导向的产品创新模式。
