我国英语交际教学概观

语言交际教学法的主要理论依据是Ｃｈｏｍ ｓｋｙ 的转换生成语法、Ｈｙｍ ｅｓ和Ｈａｌｌｉｄａｙ 的社会语言学、Ａｕｓｔｉｎ 的用语言的做事论、Ｓｅａｒｌｅ 的言语行为论、Ｋｒａｓｈｅｎ 的语言习得说、Ｗｉｌｋｉｎｓ的意念大纲和Ｍｕｎｂｙ 的交际大纲等。在我国英语教育界， 人们对交际教学法的看法大致有三： 肯定、否定、折衷， 其主要代表分别是ＣＥＣＬ理论体系、传统教学法、《高等学校英语专业基础阶段英语教学大纲》和 《新编英语教程》     

空中防撞系统避撞机制的数学模型

在TCAS系统中,到达最接近点的时间Tau、HMD和VMD是描述空中碰撞物理过程的主要参数,利用该组参数能够完整地描述TCAS系统的防撞机制。该文通过对到CPA时间的近似,引入对Tau时间的物理解释;并通过坐标变换,采用本机和入侵飞机的相对距离、相对距离变化率和相对距离加速度推导出了HMD的数学表达式;分析了工程实际应用中的修正模型。

German family policy at the crossroads: analysing the impact of parental leave reform through simulation

Comparative studies of welfare reforms encounter two problems. First, the counterfactual problem is that in the real world schemes and their reforms do not coexist simultaneously and are hard to compare. Second, the contextual problem derives from the absence of comparable measures for change. Microsimulation helps to overcome these problems. It compares policy options – actual reforms or reform plans – simultaneously and provides a comparable measure: the disposable income of model families. This article uses a type–case approach to investigate recent reforms of the German parental leave benefit. Simulation makes those reforms comparable over time and across countries. Results show that the profile of the German scheme is changing from 'general family' towards 'dual-earner' support. Furthermore, the recent reforms make the German scheme converge towards the Swedish leave scheme. The recent reforms introduce a new concept of fairness and a focus on gender equality to German family policies.     

低学业成就者的汉译英SBI教学模式

目前我们汉译英的课堂教学模式过于简单且效率低下,本文提出了一种针对低学业成就者的、基于学习策略培训的汉译英SB I教学模式,从汉语语义结构分析、英语句子结构定型、英语词汇选择以及检查核对等多方面尝试将汉译英学习策略的培训渗透到汉译英的课堂教学活动中,以期提高这些学习者的汉译英技能,帮助他们掌握必要的语言学习策略,培养他们的自主学习能力,改善课堂教学效果。     

A Likelihood‐Based Analysis for Relaxing the Exclusion Restriction in Randomized Experiments with Noncompliance

The exclusion restriction is usually assumed for identifying causal effects in true or only natural randomized experiments with noncompliance. It requires that the assignment to treatment does not have a direct causal effect on the outcome. Despite its importance, the restriction can often be unrealistic, especially in situations of natural experiments. It is shown that, without the exclusion restriction, the parametric model is identified if the outcome distributions of various compliance statuses are in the same parametric class and that class is a linearly independent set over the field of real numbers. However, the relaxation of the exclusion restriction yields a parametric model that is characterized by the presence of mixtures of distributions. This scenario complicates the likelihood‐based estimation procedures because it implies more than one maximum likelihood point. A two‐step estimation procedure based on detecting the root that is closest to the method of moments estimate of the parameter vector is then proposed and analyzed in detail, under normally distributed outcomes. An economic example with real data concerning returns to schooling concludes the paper.

双趋与双避决策情景的ERPs研究

为了研究双趋与双避冲突情景所诱发的脑电成分的差异,本研究分别记录了16名健康大学生被试在双趋、双避、无冲突三种不同情景下完成决策任务的反应时数据与脑电成分.结果表明：（1）被试在冲突情景下的决策反应时均长于无冲突情景,其中双趋冲突下反应时长于双避冲突；（2）双趋冲突情景诱发的P2的波峰值更高,潜伏期也更短,无冲突情景所引发的P2波峰值最小,潜伏期最长；（3）冲突情景与无冲突情景在300 ～ 400 ms之间出现了LPC的分离,动机冲突比无冲突情景诱发的LPC更正.本研究中脑电数据与行为数据得出一致性结果,双趋比双避情景诱发更深程度的负性情绪与注意唤醒,即较高的动机冲突.     

论二语语用发展研究认知路向

"未来的研究需从心理学的不同角度,包括认知理论和社会文化理论考虑学习者的二语语用习得。"Kasper和Rose的这一设想,不仅为二语语用发展研究提出了新思路,也提出了挑战。建立在语用普遍性基础之上的二语语用发展研究,在继承传统语用研究成果的同时,汲取体验认知语用的研究成果,将概念能力发展和隐喻能力发展作为一种新的研究路向。这既有必要,也有可能。
