Multiple imputation of missing data with ante-dependence covariance structure

A controlled clinical trial was conducted to investigate the efficacy effect of a chemical compound in the treatment of Premenstrual Dysphoric Disorder (PMDD). The data from the trial showed a non-monotone pattern of missing data and an ante-dependence covariance structure. A new analytical method for imputing the missing data with the ante-dependence covariance is proposed. The PMDD data are analysed by the non-imputation method and two imputation methods: the proposed method and the MCMC method.

知识经济对大学教育与大学生学习变革的要求

知识经济对大学教育的变革已成为科教兴国的重要焦点:知识经济的时代特点决定了大学文化的价值取向是创新;也引发了大学的学习革命———维持性学习必须向创新性学习过渡;还要以通才式的信息技术教育夯实学生的创造素质基础;更是邓小平“三个面向”与江泽民“创新”思想对大学教育要紧随时代变化要求的具体落实。知识经济时代还要求大学生注重有利于创新精神培养的个性化、多样化与交互学习;还要创造性参与大学教育模式由传统向现代的变革过程,面对信息的全球开放性更要学会选择性学习。     

Four‐Month Attentional Regulation and Its Prediction of Three‐Year Compliance

The extent to which 4‐month attentional regulation during an infant‐mother still‐face situation and 12‐month attachment security during the Strange Situation predicted rates of compliance and noncompliance during a cleanup task at 36 months was examined longitudinally in 70 infant‐mother dyads. Hierarchical multiple regression analyses indicated that infants who showed more attentional regulation during the still‐face situation with mothers later showed a higher rate of committed compliance and a lower rate of situational compliance during cleanup with mothers. Furthermore, lower levels of attentional regulation were later associated with higher rates of assertive behavior, but only for infants in an insecure attachment relationship.     

高职院校培养创业型人才的几点思考

高等职业教育是社会经济发展到一定阶段的产物，并随着社会经济的发展而不断发展，是一种以传授职业知识和技能、以培养各类职业化人才为主要目标的教育，它和创业教育目标、内容、途径都非常相关。但是，旧的职业教育观把职业教育仅仅看成是一种就业教育，这就难免导致培养目标偏窄、教育要求偏低、教学内容偏专，培养的学生虽掌握了一技之长，但社会适应能力较差。在市场经济迅速发展、科学技术日新月异的今天，这种职业教育观显然已经陈旧，     

《新青年》与《甲寅》月刊之历史渊源—《新青年》创刊史研究之一

1915年9月创刊的《新青年》，在其创刊之初，与《甲寅》月刊之间，在主编，撰稿人队伍，发刊宗旨，栏目设置，刊物风格等方面存在着很深的渊源关系，清理它们之间的这种关系，有助于更深入而全面地认识五四新文化运动的形成和发展。     

商法价值论

商法的价值是指商事法律规范对于社会和个人及其群体的积极意义。它体现商法精神 ,统领商事立法、执法和司法的全过程。商法作为带有公法化倾向的私法 ,既具法的一般价值 ,又有其自身的特殊价值。国家、个人、社会或营利皆不能作为商法本位。将贸易本位作为商法本位 ,既符合商法发达史的实际 ,也与现代商法发展的主旋律合拍。贸易本位是商法价值的基础。交易效率价值、交易安全价值和交易公平价值构成了当代商法的三大基本价值     

上海股票市场波动实证性研究:2001--从交易方式角度透视

我国股票市场上的交易方式有两种,即集合竞价和连续竞价,交易方式的差异会对股价的波动性产生影响,而市场的波动性对股票市场而言是双刃剑,因此从交易方式角度探求股市的适度波动成为理论工作的一个重心.本文以上海股票市场为研究对象,针对2001年的全部交易数据进行实证研究.结果表明,集合竞价形成的开盘价格收益率的方差大于连续竞价形成的收盘价格收益率的方差,其原因在于集合竞价与连续竞价相比,其交易过程的透明度差和交易指令具有不可更改性,据此,从交易制度上提出政策建议.
