为了创造性地贯彻《马克思主义基本原理概论》新教材的精神，课程组制定了“共性中创个性”的教学战略，在坚持共性、弘扬共性的基础上创造个性化教学特色，创造出了“坚持集体备课，鼓励多样化教学”的教学模式。     

Almost Consistent Estimation of Panel Probit Models with “Small” Fixed Effects

We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small Tand large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators differ w.r.t. the choice of instruments and whether they use trimming to reduce the bias or not. In a Monte Carlo study, we compare these estimators with pooled probit and conditional logit estimators for different data generating processes. The results show that the proposed estimators outperform these competitors in several situations.     

约翰·福尔斯小说中的“剧中剧”

约翰·福尔斯的小说《魔法师》和《法国中尉的女人》在结构上模仿了莎士比亚《暴风雨》的“剧中剧”设置。这种设置给小说中的人物提供了一个“寻找自我”的舞台，福尔斯借此探索了人的自我本质以及个体自由，表达了存在主义人文关怀的创作思想。     

论前期创造社艺术主张之成因

前期创造社"为艺术而艺术"的主张是在与文学研究会的论争中作为一种策略被提出来的,创造社同人自己对此缺乏真诚的信仰,也没有真正践行这种艺术主张,一旦在文坛站稳脚跟,他们也就抛弃了这一主张,转而大力提倡"为人生的艺术"和"革命文学",从而造成了所谓"方向大转换"的假相。     

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.     

论英语专业教学中学生非智力因素的培养

非智力因素是保证成功进行各种活动的必要心理条件。在英语专业课程学习中,学生的非智力因素能够直接转化为学习动机,把学习当作自觉行为。教师应注重学生兴趣、情感、意志、性格等非智力因素的培养,讲究教学艺术,建立宽松互动的学习环境,使学生的非智力因素在学习中起到重要作用。     

试论适航责任

自《海牙规则》采用恪尽职责使船舶适航的责任以来,该责任已被大多数国家所采纳。适航责任的概念、构成、举证与责任承担等问题对认定承运人是否违反适航义务非常重要,《海牙规则》部分地解决了关于适航责任的争议问题。

“以美育代宗教”:中国美学的百年迷途

百年以来,“以美育代宗教”始终被以蔡元培为代表的几代美学家奉若神明。然而,百年后的今天却必须要说:“以美育代宗教”,20世纪中国美学成也在兹,败也在兹。新世纪中国美学必将从跨越“以美育代宗教”的失误开始,从而实现自身新的发展。     

"中国的教研组现象"平议

我国学校教研组从表面看,是借鉴俄国先例建立的,其实是我国特殊历史条件的产物。它不是单纯的教学研究组织,还是学校基层行政组织。它越来越名不副实,对学校教学与教师发展,既有一定积极作用,也有不可忽视的消极影响。
