利用WALL构建双主教学模式深化大学英语教学改革

作为大学英语改革的主要内容，WALL（网络辅助语言学习）为大学英语改革带来了勃勃生机。本文分析了借助WALL构建大学英语双主模式，即教师主导，学生为认知主体的教学模式的实践意义。并根据相关理论分析了新型模式下教师和学生各自的作用和角色，对如何构建双主模式深化大学英语教学改革提出了一些设想。     

烟台市水资源承载力变化的驱动力研究

阐述了水资源承载力的概念、特性及影响因素,根据烟台市各县区的统计资料,分析了烟台市自上个世纪80年代以来水资源承载力变化的总体趋势和驱动因子。结果表明:人口、社会固定资产投资和GDP是影响烟台市水资源承载力变化的主要驱动因素。通过多元线性回归模型,预测出了2005和2015年的水资源量,并进一步预测了该市的需水量和缺水量。     

A modification of Honoré's triple-link model in the synoptic problem

Summary.  In New Testament studies, the synoptic problem is concerned with the relationships between the gospels of Matthew, Mark and Luke. In an earlier paper a careful specification in probabilistic terms was set up of Honoré's triple-link model. In the present paper, a modification of Honoré's model is proposed. As previously, counts of the numbers of verbal agreements between the gospels are examined to investigate which of the possible triple-link models appears to give the best fit to the data, but now using the modified version of the model and additional sets of data.     

焦虑的诱发因素及调控方法--以体操教学为例的研究

国内外心理学对学生的焦虑与运动成绩的相关研究已成为一个专门的课题。针对焦虑对学生体操技术掌握的影响，运用运动心理学有关理论对大学生体操教学中的焦虑诱发因素进行问卷调查，归纳了体操教学中诱发学生焦虑过度的原因，并对其主要影响因素进行分析，提出了控制学生的适宜焦虑水平的方法。     

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.     

文化需求与信息资源管理的转型

由于人文环境的巨大转变及互联网文化无可匹敌的影响,21世纪的都市文化需求尤其是阅读需求,发生了革命性的变化.都市文化与人本角色的这种互动,对于社会科学信息资源的合理配置和深度开发利用,具有决定性的影响,并直接造成了信息资源管理模式的转型.重点讨论都市文化需求对信息资源合理配置的影响,以及由此产生的信息资源管理模式的转范.     

Goodness‐of‐fit methods for matched case‐control studies

The authors propose graphical and numerical methods for checking the adequacy of the logistic regression model for matched case‐control data. Their approach is based on the cumulative sum of residuals over the covariate or linear predictor. Under the assumed model, the cumulative residual process converges weakly to a centered Gaussian limit whose distribution can be approximated via computer simulation. The observed cumulative residual pattern can then be compared both visually and analytically to a certain number of simulated realizations of the approximate limiting process under the null hypothesis. The proposed techniques allow one to check the functional form of each covariate, the logistic link function as well as the overall model adequacy. The authors assess the performance of the proposed methods through simulation studies and illustrate them using data from a cardiovascular study.

探析我国金融控股公司的建立模式与监管制度

金融服务业的变革和一体化,促进了金融集团及金融控股公司的发展。我国金融控股公司有两种模式:非金融企业控股公司和银行控股公司。在监管制度上,强调应实行综合监管与分业监管相结合,从传统监管方式向风险目标值法转移,要制定对金融控股公司资本充足性的监管,建立内部的“防火墙”。
