“五四”精英与唯物史观在中国的传播和发展

唯物史观在中国的传播是由“五四”精英最早启动的，其中李大钊是先驱者，陈独秀影响力最大，李达是集大成者。随着中国共产党的成立及其革命的实践，“五四”精英在传播唯物观的同时也积极探索用唯物史观分析和指导中国的革命实践，取得了积极成果。“五四”精英传播和发展唯物史观给我们以深刻的启示，包括必须充分认识到唯物史观在指导中国革命建设中的重要地位、把传播与发展统一起来以及结合中国实际来传播和发展等。

Wilcoxon–Mann–Whitney test for stratified samples and Efron's paradox dice

Two-treatment multi-center clinical trials are the most common type of clinical trials in practice. The aim of this paper is to discuss a curious property of certain standard nonparametric procedures used in the analysis of such clinical trials. Different analyses of a simulated data example are presented, which lead to contrasting and surprising results. The source of the potentially misleading outcome is then explored while relating the simulated data with the concept of Efron's paradox dice and the notion of nontransitivity. With the root of the problem established, an alternate nonparametric method from the literature is shown to address the problem. Finally, pointing out an interpretational concern of using the alternate procedure, a modification to this procedure is also suggested and corresponding theoretical results are presented.

The analysis of incomplete data using stochastic covariates

In the development of many diseases there are often associated random variables which continuously reflect the progress of a subject towards the final expression of the disease (failure). At any given time these processes, which we call stochastic covariates, may provide information about the current hazard and the remaining time to failure. Likewise, in situations when the specific times of key prior events are not known, such as the time of onset of an occult tumour or the time of infection with HIV-1, it may be possible to identify a stochastic covariate which reveals, indirectly, when the event of interest occurred. The analysis of carcinogenicity trials which involve occult tumours is usually based on the time of death or sacrifice and an indicator of tumour presence for each animal in the experiment. However, the size of an occult tumour observed at the endpoint represents data concerning tumour development which may convey additional information concerning both the tumour incidence rate and the rate of death to which tumour-bearing animals are subject. We develop a stochastic model for tumour growth and suggest different ways in which the effect of this growth on the hazard of failure might be modelled. Using a combined model for tumour growth and additive competing risks of death, we show that if this tumour size information is used, assumptions concerning tumour lethality, the context of observation or multiple sacrifice times are no longer necessary in order to estimate the tumour incidence rate. Parametric estimation based on the method of maximum likelihood is outlined and is applied to simulated data from the combined model. The results of this limited study confirm that use of the stochastic covariate tumour size results in more precise estimation of the incidence rate for occult tumours.     

也论"五四"的主题

“五四”的主题是政治挤压下的启蒙。“五四”整个发展过程中启蒙始终不能完全脱离政治。“五四”落潮,并不是“救亡压倒启蒙”,而是启蒙自身发展和实现现代民族国家必然的客观要求。“五四”启蒙运动是不彻底的,这有其发展的历史性和客观性。因此不能脱离政治孤立地看待启蒙。

《金锁记》改写的背后

《金锁记》是张爱玲作品中唯一一篇充满斗争激越、呼应“五四”主题的文章。改写后的《怨女》则成为超越时代局限 ,走向人性深处 ,带有普泛性和恒定性主题的文章。在张爱玲的文学趣味向传统复归的背后 ,是作者对“五四”文学的反思 ,以及对中国文艺的表现方式、表现题材的寻求。     

“醒过来的人的真声音”——试论五四新文学早期小说中的爱情表达

五四新文学早期,大量的青年作家在小说创作中关注爱情主题,试图探索爱情中情感与欲望的新关系,主要的区别在于对欲望的态度,大致可以分为三种无助的精神逃避,扭曲的欲望表达和真实的欲望书写.文章阐述这三种思考与表达,分析这三种表达所内蕴的作家的思想意识,并由此指出作家们的总体追求的意义所在.
