近年《二十四诗品》真伪讨论综述

《二十四诗品》一般认为是晚唐司空图所撰,近年来其真伪问题引起学界热烈讨论,争论的焦点主要集中在对有关《诗品》文献的辨析、《诗品》的版本源流、司空图与《诗品》诗学思想的异同这三个方面,由《诗品》真伪的讨论还引起对相关问题的关注,如对古籍版本的重视,对《诗家一指》的研究等。本文综述了这场讨论中正反两方的意见,以见这场讨论的概况和意义。     

Bootstrapping regression models with BLUS residuals

To bootstrap a regression problem, pairs of response and explanatory variables or residuals can be resam‐pled, according to whether we believe that the explanatory variables are random or fixed. In the latter case, different residuals have been proposed in the literature, including the ordinary residuals (Efron 1979), standardized residuals (Bickel & Freedman 1983) and Studentized residuals (Weber 1984). Freedman (1981) has shown that the bootstrap from ordinary residuals is asymptotically valid when the number of cases increases and the number of variables is fixed. Bickel & Freedman (1983) have shown the asymptotic validity for ordinary residuals when the number of variables and the number of cases both increase, provided that the ratio of the two converges to zero at an appropriate rate. In this paper, the authors introduce the use of BLUS (Best Linear Unbiased with Scalar covariance matrix) residuals in bootstrapping regression models. The main advantage of the BLUS residuals, introduced in Theil (1965), is that they are uncorrelated. The main disadvantage is that only n —p residuals can be computed for a regression problem with n cases and p variables. The asymptotic results of Freedman (1981) and Bickel & Freedman (1983) for the ordinary (and standardized) residuals are generalized to the BLUS residuals. A small simulation study shows that even though only n — p residuals are available, in small samples bootstrapping BLUS residuals can be as good as, and sometimes better than, bootstrapping from standardized or Studentized residuals.     

Correlation in a Bayesian framework

The authors consider the correlation between two arbitrary functions of the data and a parameter when the parameter is regarded as a random variable with given prior distribution. They show how to compute such a correlation and use closed form expressions to assess the dependence between parameters and various classical or robust estimators thereof, as well as between p‐values and posterior probabilities of the null hypothesis in the one‐sided testing problem. Other applications involve the Dirichlet process and stationary Gaussian processes. Using this approach, the authors also derive a general nonparametric upper bound on Bayes risks.

脉冲YAG激光照射罗氏沼虾眼柄对卵巢发育与产卵影响的研究

本文用He-Ne激光瞄准罗氏沼虾（Macrobrachium rosenbergii)的眼柄,再用YAG脉冲激光照射眼柄的神经分泌神经,研究激光照射后罗氏沼虾卵巢的发育和产卵,结果表明,激光照射后,罗氏沼虾的卵巢发育加快,一般能提前10天产卵。     

循环经济与循环经济的法律调控

循环经济是新型工业化道路的最新、最先进的经济发展模式,循环经济的理念已不单纯是环境的保护,而是一种经济发展模式的转变。发展循环经济已成为国际社会的共识。我国应借鉴德国、日本的循环经济立法,建构科学的循环经济立法体系,制定和完善适用我国的《循环经济促进法》。     

新旧社会交替时期中国女性追求解放的历程——浅析繁漪、陈白露、愫芳

在中国现代文学史上,女性的觉醒和反抗是一个重要的传统主题。曹禺先生塑造了繁漪、陈白露、愫芳三位身处黑暗而渴望光明的女性形象,通过描述这三位女性在觉醒和反抗过程中各自表现出的不同的特点,形象地揭示了在新旧社会交替时期中国女性追求解放的艰难历程。     

山东省高校理工学报影响力分析

文章通过研究山东省21种高校理工学报2007 ～ 2011年的总被引频次、影响因子、基金论文比、来源文献量、引用刊数、地区分布数等6项指标数据,对21种学报的学术影响力进行了评价分析.数据表明:山东省高校理工学报的总体水平不高,影响力有限,且各学报规模和发展水平不平衡.针对存在的问题,山东省高校理工学报应当采取以下措施提升学报影响力:平衡综合性和专业性;找准定位,寻求突破;广开渠道,挖掘稿源.
