稻壳膨化粉栽培金针菇试验

膨化谷壳粉是一种优质的新型食用菌培养料。试验表明，用膨化谷壳和棉籽壳按1：2～1：1的比例混合栽培金针菇，鲜菇生物学效率可达110％左右，棉籽壳为主料的BE％为80％左右，但混合杂木屑以后子实体产量很低、质量较差，不宜用杂木屑或纯膨化谷壳粉进行金针菇的商业栽培。     

《古兰经》文本探究

《古兰经》文本像《圣经》一样经历了自身的正典化过程,作为这个过程结晶的奥斯曼本呈现出一些显著的文本特征和线索。把握《古兰经》的这些特征和线索,不仅有助于人们判断经章降示的顺序和主题,而且有助于从学理上纠正某些代表性的西方学者所谓《古兰经》文本存在缺陷的偏见。     

Joint estimation of multiple high‐dimensional Gaussian copula graphical models

A joint estimation approach for multiple high‐dimensional Gaussian copula graphical models is proposed, which achieves estimation robustness by exploiting non‐parametric rank‐based correlation coefficient estimators. Although we focus on continuous data in this paper, the proposed method can be extended to deal with binary or mixed data. Based on a weighted minimisation problem, the estimators can be obtained by implementing second‐order cone programming. Theoretical properties of the procedure are investigated. We show that the proposed joint estimation procedure leads to a faster convergence rate than estimating the graphs individually. It is also shown that the proposed procedure achieves an exact graph structure recovery with probability tending to 1 under certain regularity conditions. Besides theoretical analysis, we conduct numerical simulations to compare the estimation performance and graph recovery performance of some state‐of‐the‐art methods including both joint estimation methods and estimation methods for individuals. The proposed method is then applied to a gene expression data set, which illustrates its practical usefulness.

国际原油价格变化对中美能源股影响的断点研究

为准确测度原油价格与中美能源股间的关系,基于残差平方和全局最小化的原理,分析原油价格对中美能源股影响的结构性变化。结果表明:中国能源股的两个断点与美国次贷危机爆发和欧债危机结束的时间相近,美国能源股的两个断点与原油价格暴涨和暴跌的时间相近。进一步研究发现,在美国次贷危机爆发之前,原油价格对中国能源股的影响不显著,在次贷危机之后,对中国能源股的影响为正,其中在金融危机期间达到最大。而在任一区间,原油价格对美国能源股有显著的正向影响,且在原油价格上涨阶段达到最大。     

市民社会观念的当代演变及其意义

近代的市民社会观念,主要是指因商品交换关系而将人们联结起来的私人自律的经渗交往领域。20世纪,市民社会的观念发生了重大转变,主要是指自主的社会文化领域,即自治的民间社团及其活动所构成的公共领域。这两种市民社会观念都将克服市场社会中私人利益与公共利益之间的矛盾作为其理论的核心问题。不同的是,近代市民社会观念力求通过对市民社会的超越克服市场社会的内在矛盾,而当代市民社会观念则致力于在市民社会中寻求克服市场社会内在矛盾的根据和力量。市民社会观念的这一变化是对市民社会发展历史的反映,必须考察这整个演变过程,综括其丰富的内涵,才能达到对现实市民社会及其发展的全面把握。

赵尔巽与湖南近代教育的发展

赵尔巽(1844-1927年),字公镶,号次珊,又号无补,汉军正蓝旗人.原籍辽宁铁岭,世居山东泰安.署户部尚书、盛京将军、湖广总督、四川总督、东三省总督等职,是清末满洲贵族中少有的干才,也是当时比较有见识和作为的封疆大吏.赵尔巽于1903年4月至1904年6月担任湖南巡抚,是清末湖南颇有影响力的巡抚之一.抚湘期间,他励精图治,厉行新政,并把发展教育作为新政的"首务"、"急务"、"第一要务",大力进行书院改制、整顿原有学堂、开办新式学堂等活动,极大地推动了湖南近代教育的发展.而且,赵尔巽的教育思想和实践具有鲜明的特色,在清末新政时期的督抚大员中具有一定的代表性,这对我们今天发展教育事业仍不乏借鉴意义.

Adaptive test for mean vectors of high-dimensional time series data with factor structure

Statistical inference of high-dimensional time series data is of increasing interest in various fields such as social sciences and biology. In this article, we consider the problem of testing the equality of high-dimensional mean vectors in the approximate factor model, which allows for time series dependence among distinct observations and more flexible dependence within observations. We propose a data-adaptive test based on the factor-adjusted data rather than on the directly observed data. By combining the tests with different norms, the proposed test adapts to various alternative scenarios and thus overcomes the shortcomings of the tests based either on $L_2$-norm or $L_{\infty }$-norm. Multiplier bootstrap method is utilized to approximate the true underlying distribution of the proposed test statistics. Theoretical analysis shows that the proposed test enjoys desirable properties. Besides, we conduct thorough numerical study to compare the empirical performance of the proposed test with some state-of-the-art tests. A real stock market data set is analyzed to show the empirical usefulness of the proposed test.
