论李燮和与辛亥上海光复

在辛亥上海光复过程中,光复会第三号领袖人物李燮和的功劳最大,但他在随后争夺沪军都督时首先被排挤出局,则是他自身诸多不足所造成的。李燮和在辛亥上海光复过程中所表现出来的不计个人名利得失、顾全革命大局的高姿态值得大书一笔,这是整个辛亥革命史上的一个亮点。后来的国民党官方史学家们以李燮和后来参加“筹安会”为口实,刻意贬低李燮和在上海光复中的作用与贡献,是站不住脚的,也是不足取的。

Lower bounds on expectations of positive L-statistics from without-replacement models

We consider samples drawn without replacement from finite populations. We establish optimal lower non-negative and upper non-positive bounds on the expectations of linear combinations of order statistics centered about the population mean in units generated by the population central absolute moments of various orders. We also specify the general results for important examples of sample extremes, Gini mean differences and sample range. The paper completes the results of Papadatos and Rychlik [2004. Bounds on expectations of L-statistics from without replacement samples. J. Statist. Plann. Inference 124, 317–336], where sharp negative lower and positive upper bounds on the expectations of the combinations were presented for the without-replacement samples.     

论奥斯古德对昆明高峣社区的人类学研究

1938年夏天,美国年轻学者科尼利尔斯·奥斯古德为了履行与燕京大学的合作计划,不远万里来到滇池西岸一个名不见经传的小村庄调查.1961年,他开启尘封的笔记本,整理旧资料,补充新文献,完成了<旧中国的农村生活:对云南高峣的社区研究>.70年过去,重温科尼利尔斯·奥斯古德的研究历程,我们仍会从中获得许多有益的启示.     

Bias Correction in the Dynamic Panel Data Model with a Nonscalar Disturbance Covariance Matrix

Approximation formulae are developed for the bias of ordinary and generalized Least Squares Dummy Variable (LSDV) estimators in dynamic panel data models. Results from Kiviet [Kiviet, J. F. (1995), on bias, inconsistency, and efficiency of various estimators in dynamic panel data models, J. Econometrics68:53-78; Kiviet, J. F. (1999), Expectations of expansions for estimators in a dynamic panel data model: some results for weakly exogenous regressors, In: Hsiao, C., Lahiri, K., Lee, L-F., Pesaran, M. H., eds., Analysis of Panels and Limited Dependent Variables, Cambridge: Cambridge University Press, pp. 199-225] are extended to higher-order dynamic panel data models with general covariance structure. The focus is on estimation of both short- and long-run coefficients. The results show that proper modelling of the disturbance covariance structure is indispensable. The bias approximations are used to construct bias corrected estimators which are then applied to quarterly data from 14 European Union countries. Money demand functions for M1, M2 and M3 are estimated for the EU area as a whole for the period 1991: I-1995: IV. Significant spillovers between countries are found reflecting the dependence of domestic money demand on foreign developments. The empirical results show that in general plausible long-run effects are obtained by the bias corrected estimators. Moreover, finite sample bias, although of moderate magnitude, is present underlining the importance of more refined estimation techniques. Also the efficiency gains by exploiting the heteroscedasticity and cross-correlation patterns between countries are sometimes considerable.     

解读池莉小说创作的主体意识

李白乐府诗歌《蜀道难》等三首同音重复的语言风格

李白三十多岁初入长安时期创作的乐府诗歌《蜀道难》、《行路难》、《将进酒》是其诗歌创作第一高峰时期的代表作。本文运用汉语韵律学的理论,分析李白《蜀道难》等三首乐府诗歌中运用同音重复手段所产生的一唱三叹、突出主题、加重感情等音韵魅力和语言风格,揭示了作品中语言风格与托物言志的意境、“挥斥幽愤”的思想感情是融为一体的,让读者从新的角度体味李白乐府诗歌崇高的浪漫主义意境。     

浅谈电子商务涉及的法律问题

近年来,电子商务发展迅速,对社会生活产生了很大影响,并逐渐形成了一种新型的社会关系。与此同时,电子商务领域中也出现了涉及商法、刑法、民法、知识产权和国际法等许多亟待解决的法律问题。因此,分析电子商务活动中诸多涉及法律的问题及产生的原因,在遵循国际示范法的标准并借鉴国外的先进经验的同时,结合我国的国情制定出适合我国的电子商务法律,对促进我国电子商务的健康、有序、规范发展是非常必要的。     

马克思主义实践哲学在中国的早期传播

十月革命开创了世界历史的新纪元.从克利姆林宫传出来的马克思主义,对亚、非、拉人民是一个有力的号召.李大钊、陈独秀对马克思主义,特别是马克思主义哲学中的历史唯物主义给予高度重视和热情宣传,为马克思主义在中国的传播,为中国共产党的创建做出了巨大贡献.
