氨汞化合物的性质研究

通过实验讨论了二价汞盐与氨反应生成的氨汞沉淀在过量氨水 ,铵盐及氨性缓冲溶液和常见酸中的溶解性 提出 :在NH3·H2 O_NH4NO3 溶液中 ,二价汞与氨水反应生成可溶性氨配合物 ,沉淀溶解 ;在H 与配离子Cl-,Br-,I-,SCN-等共存时 ,氨汞沉淀也能形成配合物而溶解 ;单一Cl-的存在不利于氨汞沉淀的溶解 同时 ,还从配位平衡 ,硬软酸碱理论 ,结构等方面对实验现象作了简要解释     

中外叙事文学中的“后母／继子乱伦”叙事——“乱伦”母题与中外叙事文学研究系列论文之一

“后母／继子乱伦”叙事模式的作品触及人类集体无意识中的“乱伦情结”与“乱伦禁忌”的深层心理。后母／继子乱伦”现象是专制的父权文化的产物，“后母”乃至“继子”承载着对父权文化的批判与表现人性解放的双重道德任务，表现了一种“渎父”或“精神弑父”的主题。她（他）们的悲剧性的命运结局体现了作家对这种现象微妙而复杂的态度：在无限宽容的同时，也隐含对乱伦原罪感几分不自觉的认同。     

ON BOOTSTRAP HYPOTHESIS TESTING

We describe methods for constructing bootstrap hypothesis tests, illustrating our approach using analysis of variance. The importance of pivotalness is discussed. Pivotal statistics usually result in improved accuracy of level. We note that hypothesis tests and confidence intervals call for different methods of resampling, so as to ensure that accurate critical point estimates are obtained in the former case even when data fail to comply with the null hypothesis. Our main points are illustrated by a simulation study and application to three real data sets.     

多次采样与希尔伯特变换

针对文献［１］提出的多次采样方法，证明了多次采样法在一定条件下等效于一种希尔伯特变换器，并用数据证明：当信号的相对带宽小于８０％时，９次采样所获得的正交分量误差可忽略。     

经济增长对收入分配的影响——来自中国的实践验证

经济增长对收入分配会产生何种影响,一直是经济学中相当重要的问题。围绕着库兹涅茨倒U假说的研究表明,经济结构在解释经济增长与收入分配的相互关系时有重要的作用。本文建立了一系列模型用来解释中国近二十年来的经济增长是如何影响收入分配的,并采用1990-2005年中国经济的相关数据对该模型进行验证,表明了经济增长本身会在两个方面对收入分配产生影响,最终的作用是扩大了收入差距还是缩小了收入差距取决于经济结构的变动,其中城乡二元结构的变动起到了至关重要的作用。     

“经济人”假说的演变及其现实意义

自亚当·斯密提出“经济人”假说，至今已历时二百余年，期间“经济人”假说不断发展，逐渐由“传统经济人”演变为“新经济人”。“经济人”假说和“看不见的手”理论共同支撑着经济学大厦的发展。本文在对“经济人”假说进行综述的基础上，结合其演变，进一步阐明“经济人”假说对建设社会主义市场经济体制、建设和谐社会和良好人际关系的理论和现实意义。     

乌托邦情结的消解——中国“后新时期”文学创作的一种精神向度及其文化品性

乌托邦作为一种人文主义的理想 ,是历代具有使命和责任感的作家的精神追求。本文拟就 80年代中期以来 ,中国文学领域出现的一种反乌托邦创作倾向 ,阐述文学作品在削弱和厌弃了精神性力量之后 ,具有明显的后现代文化品性这一观点。其表现为 :深度意义的消失 ,历史意识被抹去 ,主体的跌落等。并指出 ,反乌托邦作品是以消解理想主义谜底的方式重设虚无的寓言。     

Exposure to occupational violence and the buffering effects of intra-oranizational support

This paper presents a conceptually distinct analysis of the data first reported by Leather et al. Specifically, it investigates the effects of exposure to a variety of forms of work-related violence upon work attitudes and general well-being within a sample of UK public house licensees—individuals who manage public houses and hold the licence permitting the sale of alcoholic drinks on the premises. In addition, it examines the role of social support in moderating such effects. Based upon a sample of 242 licensees, it reports a consistent interaction between exposure to such violence and the availability of perceived intra-organizational support in determining the size of any negative effects upon individual well-being, job satisfaction and organizational commitment. It is argued that exposure to all forms of work-related violence, including intimidation, verbal abuse and threat, should be seen as a potential stressor within the work environment, the negative effects of which are buffered by perceived support from within the organization, but not by that perceived to be available from informal sources such as family and friends.     

Properties of Bayes Factors Based on Test Statistics

Abstract.  This article examines the consistency, interpretation and application of Bayes factors constructed from standard test statistics. Primary conclusions are that Bayes factors based on multinomial and normal test statistics are consistent for suitable choices of the hyperparameters used to specify alternative hypotheses, and that such constructions can be extended to obtain consistent Bayes factors based on likelihood ratio statistics. A connection between Bayes factors based on likelihood ratio statistics and the Bayesian information criterion is exposed, as is a connection between Bayes factors based on F statistics and parametric Bayes factors based on normal-inverse gamma models. Similarly, Bayes factors based on chi-squared statistics for multinomial data are shown to provide accurate approximations to Bayes factors based on multinomial/Dirichlet models. An illustration of how the simple form of these Bayes factors can be exploited to generate easily interpretable summaries of the experimental 'weight of evidence' is provided.
