从分笔交易数据透视中国债券市场流动性

采用分笔交易数据,用相对买卖价差分析我国债券市场流动性,可以得出如下结论:各期限国债流动性差异不大,短期和长期国债流动性相对较好;国债买卖价差最小,可转债累计深度最大;债券市场流动性和波动性特征之间存在紧密的内在联系。     

图式理论、学习策略与大学英语口语教学

本研究采用定量分析的方法,对84名天水师范学院非英语专业的学生的口语水平进行测试。根据图式理论,口语任务分为有关键词及句型提示类和无提示类,并对被试的学习策略使用情况做了调查,结果发现,口语任务有提示与无提示对学生的口语成绩有显著影响,这说明图式理论完全适用于大学英语口语教学。     

对外文化教学中的主体意识略论

在一般的人类实践活动中,主体与客体的关系往往是主动与被动、决定与被决定的关系。但在对外文化教学实践活动中,由于教者与学者都是主体,原来的主体与客体之间的主动与被动、决定与被决定关系变成了第一主体与第二主体之间的平行互动、共生互决关系。在目前第二主体及其意识还未被关注的状况下,我们尤其要提倡以第二主体为中心的人本主义教育思想与教学方法,充分考虑和尊重作为第二主体即外籍学生的学习动机、感情倾向和价值观。     

STTEPping in the right direction? Western classical music in an orchestral programme for disadvantaged African youth

This article looks at STTEP, an outreach project currently housed at the University of Pretoria, which concentrates on the teaching of western orchestral instruments, plus background areas such as music theory, to disadvantaged children and youth from a variety of townships around Pretoria, South Africa. STTEP’s direction can well be described as ‘right’ – pupils are already surrounded by all kinds of global phenomena, and their formal music studies in western classical music are not making them forget their roots. In fact, the contrary has been found to be the case and some interesting cultural fusions are already seen – always a sign of a living culture.     

局部理性市场的预期分析

在一个发育不完善、组织效率较低的商品或资本市场中,不同的市场主体拥有不同信息并产生预期模式的差异,由于交易者之间的信息屏障在短期内无法有效消除,导致预期的异质化长期存在并使市场仅具有局部理性.局部理性市场价格的稳定性取决于理性投机与非理性交易行为的力量对比,而不成熟市场经常显现的过度波动性则往往是理性投机处于弱势的表现.

Model diagnostics for smoothing spline ANOVA models

The author proposes some simple diagnostics for assessing the necessity of selected terms in smoothing spline ANOVA models. The elimination of practically insignificant terms generally enhances the interpretability of the estimates and sometimes may also have inferential implications. The diagnostics are derived from Kullback‐Leibler geometry and are illustrated in the settings of regression, probability density estimation, and hazard rate estimation.     

Issues in applying recent CPMP ‘Points to Consider’ and FDA guidance documents with biostatistical implications

The International Conference on Harmonisation guideline ‘Statistical Principles for Clinical Trials’ was adopted by the Committee for Proprietary Medicinal Products (CPMP) in March 1998, and consequently is operational in Europe. Since then more detailed guidance on selected topics has been issued by the CPMP in the form of ‘Points to Consider’ documents. The intent of these was to give guidance particularly to non‐statistical reviewers within regulatory authorities, although of course they also provide a good source of information for pharmaceutical industry statisticians. In addition, the Food and Drug Administration has recently issued a draft guideline on data monitoring committees. In November 2002 a one‐day discussion forum was held in London by Statisticians in the Pharmaceutical Industry (PSI). The aim of the meeting was to discuss how statisticians were responding to some of the issues covered in these new guidelines, and to document consensus views where they existed. The forum was attended by industry, academic and regulatory statisticians. This paper outlines the questions raised, resulting discussions and consensus views reached. It is clear from the guidelines and discussions at the workshop that the statistical analysis strategy must be planned during the design phase of a clinical trial and carefully documented. Once the study is complete the analysis strategy should be thoughtfully executed and the findings reported. Copyright © 2003 John Wiley & Sons, Ltd.
