The design of organizations and the right to act

Recent innovations in the structure of formal organizations suggest possible directions for the design of schools to bring about high achievement. The structure of output-driven in contrast to administratively-driven schools is described, and designs are described which address both the goal of high achievement and the goal of reduced inequality.An earlier version of this paper was presented as the author's Sorokin Lecture at the annual meeting of the Eastern Sociological Society, Boston, March 1993.     

Perception of Ecological Risk to Water Environments

This paper examines lay and expert perceptions of the ecological risks associated with a range of human activities that could adversely affect water resource environments. It employs the psychometric paradigm pioneered in characterizing perceptions of human health risks, which involves surveys to obtain judgments from subjects about risk items in terms of several important characteristics of the risks. The paper builds on a previous study that introduced ecological risk perception. This second study employs a larger, more diverse sample, a more focused topic area, and comparisons between lay and expert judgments. The results confirm that a small set of underlying factors explain a great deal of variability in lay judgments about ecological risks. These have been termed Ecological Impact, Human Benefits, Controllability , and Knowledge. The results are useful in explaining subjects' judgments of the general riskiness of, and need for regulation of, various risk items. The results also indicate several differences and areas of agreement among the lay and expert samples that point to potential key issues in future ecological risk management efforts for water resources.     

经济收敛理论与检验方法研究综述

在大量文献研究的基础上,对收敛问题的产生及收敛概念的发展作了全面概括,并对绝对收敛、条件收敛、俱乐部收敛和σ收敛作了深入辨析,对各种识别方法作了全面归纳。归纳了对世界大多数国家和地区数据所作识别的结果。还从收敛理论与传统理论的冲突与协调方面作了深入分析。最后对近年收敛研究的深化与扩展研究的趋势作了概括。     

非畅流流域跨界水污染纠纷管理模型研究

结合我国流域的非畅流特点,提出了流域各地区作为独立决策单元、污染物人为调控和地区间污染物间接不影响等几个基本假设,构建了我国流域跨界水污染描述模型.分析了我国目前正在执行的污染物削减指令配额模型的优缺点,提出用行政、税收、排污权交易等手段解决我国日益严重的流域跨界水污染纠纷问题,为此建立了合作协调模型、税收宏观调控模型、排污权交易宏观调控模型.通过对淮河流域跨界水污染纠纷的具体应用分析了各种管理模型的资源利用效率.最后,通过各种管理模型的对比分析,指出选择合适的管理模型应与流域的实际情况相匹配.     

流域跨界水污染纠纷税收调控管理模型研究

在分析我国目前的指令配额管理模型和排污收费制度存在的诸多问题的基础上,提出用税收手段解决我国日益严重的流域跨界水污染纠纷的思路。结合我国流域的非畅流特点,提出了污染物人工调控和污染物间接不影响等几个基本假定,构建了流域跨界水污染结构描述模型。建立了流域跨界水污染税收调控Stackelberg博弈模型,并用理想点法求解出博弈模型的数值解。通过淮河流域的实证分析,得出税收调控管理模型明显优于指令配额管理模型的结论。最后分析了影响税收调控管理模型实施效果的诸多因素。     

基于主体不平等的跨国界河流水资源分配的破产博弈研究

基于破产理论和讨价还价博弈,构建水资源分配的破产博弈模型。借鉴国际水法,构建主体在水资源分配谈判中的议价能力评价指标体系,将议价能力运用到破产博弈模型中,突出主体在水资源分配中的不平等性,减少水资源分配量与贡献、需求量和对水资源依赖程度的非对称性;结合主体的谈判破裂点,根据主体满意度函数的联动函数寻找水资源分配的最优解,使分配能同时满足个体理性和集体理性,并对澜沧江-湄公河流域进行实例研究。     

水信息披露、机构投资者异质性与企业价值——来自我国A股制造业上市公司的经验证据

以我国2011-2016年A股制造业上市公司为研究样本,本文采用面板回归模型实证检验了企业水信息披露对企业价值的影响以及异质机构投资者在二者关系中的调节作用。结果表明：目前企业水信息披露水平整体较低,其对企业价值有显著的负向影响;在该影响中,机构投资者整体有显著的正向调节作用,压力抵制型机构投资者有显著的负向调节作用,而压力敏感型机构投资者无显著的调节作用。     

A new test for multivariate normality by combining extreme and nonextreme BHEP tests

In this article, we propose a new multiple test procedure for assessing multivariate normality, which combines BHEP (Baringhaus–Henze–Epps–Pulley) tests by considering extreme and nonextreme choices of the tuning parameter in the definition of the BHEP test statistic. Monte Carlo power comparisons indicate that the new test presents a reasonable power against a wide range of alternative distributions, showing itself to be competitive against the most recommended procedures for testing a multivariate hypothesis of normality. We further illustrate the use of the new test for the Fisher Iris dataset.
