论《所罗门之歌》中的布鲁斯美学

布鲁斯是由美国黑人创造的音乐流派。美国黑人女作家托尼.莫里森用文字来吟唱布鲁斯,其小说《所罗门之歌》中一首古老的布鲁斯歌曲贯穿全文始终,整部小说洋溢着浓厚的布鲁斯美学。本文从布鲁斯美学的角度探讨黑人的身份认同、文化传统的回归。     

Nonresponse weighting adjustment using estimated response probability

To reduce nonresponse bias in sample surveys, a method of nonresponse weighting adjustment is often used which consists of multiplying the sampling weight of the respondent by the inverse of the estimated response probability. The authors examine the asymptotic properties of this estimator. They prove that it is generally more efficient than an estimator which uses the true response probability, provided that the parameters which govern this probability are estimated by maximum likelihood. The authors discuss variance estimation methods that account for the effect of using the estimated response probability; they compare their performances in a small simulation study. They also discuss extensions to the regression estimator.     

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。     

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.

An alternative to model selection in ordinary regression

The weaknesses of established model selection procedures based on hypothesis testing and similar criteria are discussed and an alternative based on synthetic (composite) estimation is proposed. It is developed for the problem of prediction in ordinary regression and its properties are explored by simulations for the simple regression. Extensions to a general setting are described and an example with multiple regression is analysed. Arguments are presented against using a selected model for any inferences.     

A simple estimator for a shared frailty regression model

Summary. We propose a simple estimation procedure for a proportional hazards frailty regression model for clustered survival data in which the dependence is generated by a positive stable distribution. Inferences for the frailty parameter can be obtained by using output from Cox regression analyses. The computational burden is substantially less than that of the other approaches to estimation. The large sample behaviour of the estimator is studied and simulations show that the approximations are appropriate for use with realistic sample sizes. The methods are motivated by studies of familial associations in the natural history of diseases. Their practical utility is illustrated with sib pair data from Beaver Dam, Wisconsin.

主审法官负责制的实现条件及当前应解决的问题

主审法官负责制是人民法院为实现司法公正解决司法独立问题所进行的内部结构性改革,在推行时须注意五大实现条件和解决好当前存在的三大问题。在实现条件上,要求主审法官有较高的业务素质和良好的政治道德素质,为此,应搞好法官的选任工作,在此基础上,建立完善的法官任职保障、物质保障制度和落实主审法官职务上的权利和义务。而须解决的三大问题是,当前应对现有法官队伍进行选拔淘汰并合理分流,对已任或新任法官加强培养工作,增强其业务技能,对行政化的审判业务运作机制应予以消除,实现主审法官独立办案。
