大学英语能力教学迫在眉睫

自从我国面向世界、改革开放以来,我国的英语教学就同时兴旺起来.近年来,大学英语教学界十分活跃,科研、改革的尝试在全国各地层出不穷,这难能可贵.但是近年来,特别是加人WTO以后,更加国际化的中国,自上而下,都对大学英语能力教学的现状表示不满足.首先分析现时大学英语能力教学中存在的问题,然后讨论社会上的英语教学和PETS等新推出的测试模式,对大学英语及其测试模式形成压力;最后,就如何完善大学英语能力教学提出建议.

A Non-parametric Frailty Model for Temporally Clustered Multivariate Failure Times

Abstract A model is introduced here for multivariate failure time data arising from heterogenous populations. In particular, we consider a situation in which the failure times of individual subjects are often temporally clustered, so that many failures occur during a relatively short age interval. The clustering is modelled by assuming that the subjects can be divided into ‘internally homogenous’ latent classes, each such class being then described by a time‐dependent frailty profile function. As an example, we reanalysed the dental caries data presented earlier in Härkänen et al. [Scand. J. Statist. 27 (2000) 577], as it turned out that our earlier model could not adequately describe the observed clustering.     

简论司马迁的人生价值观

司马迁的人生价值观是他“一家之言”的重要组成部分,也是中华民族宝贵的精神财富。司马迁把“立德”、“立言”、“立功”作为人生的三大价值取向,认为在挫折和逆境中忍辱奋进是取得巨大成功的重要条件,在他看来,人们应当珍视生命,面对死亡应有崇高的价值追求,要死得其所,要死得有价值。

分歧共识展望--10余年来国内全球化理论研究述评

由于主客观方面的多种原因，我国学者对全球化若干问题和理论观点的认识存在诸多分歧：全球化是客观的自然过程，还是主观的意识形态；全球化是单一的经济全球化，还是政治、文化、社会等整体的全球化；全球化是趋同化、一体化、单质化，还是多样化、民族化、异质化；全球化是物的全球化，还是人的全球化；等等。不同思想、观点相互碰撞、交锋，在争议中逐渐达成了一些基本共识：全球化至少经济全球化是一种客观存在；全球化是一种动态的过程；经济全球化不可避免地对世界政治、文化和社会生活产生影响；全球化具有主客观性：全球化过程内在地充满着矛盾；全球化是机遇与挑战并存，利益与弊端同在；现实的全球化是不公平的；等等。正确认识我国全球化理论研究中存在的问题，有利于明确下一阶段的努力方向。

Uncertain Numbers and Uncertainty in the Selection of Input Distributions—Consequences for a Probabilistic Risk Assessment of Contaminated Land

Risks from exposure to contaminated land are often assessed with the aid of mathematical models. The current probabilistic approach is a considerable improvement on previous deterministic risk assessment practices, in that it attempts to characterize uncertainty and variability. However, some inputs continue to be assigned as precise numbers, while others are characterized as precise probability distributions. Such precision is hard to justify, and we show in this article how rounding errors and distribution assumptions can affect an exposure assessment. The outcome of traditional deterministic point estimates and Monte Carlo simulations were compared to probability bounds analyses. Assigning all scalars as imprecise numbers (intervals prescribed by significant digits) added uncertainty to the deterministic point estimate of about one order of magnitude. Similarly, representing probability distributions as probability boxes added several orders of magnitude to the uncertainty of the probabilistic estimate. This indicates that the size of the uncertainty in such assessments is actually much greater than currently reported. The article suggests that full disclosure of the uncertainty may facilitate decision making in opening up a negotiation window. In the risk analysis process, it is also an ethical obligation to clarify the boundary between the scientific and social domains.
