非英语专业大学生词汇习得策略的实证研究

本文通过调查和分析我国非英语专业大学生英语学习中词汇习得策略的使用情况及其关于英语词汇习得策略的看法，发现他们最常用的是根据上下文猜测词义策略和反复学习策略。据此，本文提出了大学英语词汇教学中应注意的四个因素。     

网络词汇的变化与语言的自调节功能

汉语的自我调节功能对网络词汇的改变起了根本作用。通过"补位"和"过滤"两阶段的自我调节,网络词汇正从表面无序走向有序。在汉语自我调节功能作用下,网络词汇将健康地发展。

第二语言基础阶段习得机智探讨

语言首先是符号,无论是表音符号还是表义符号。音义本身本来也是符号,只不过在标记音义的符号诞生前没有具体的符号去标注声音和记述其意义罢了。因此,从符号表注语音和语义的角度看,第二语言的习得过程,尤其是第二语言基础阶段习得过程有一定的共同规律可循。本文试图从这一角度出发,探索第二语言基础阶段习得机智,并将“语言”这一概念的内涵发展,以提高第二语言基础阶段学习的效率。     

汉语语词衍生义探析

近年来,由于新事物的出现,人们思维方式和生活方式的变化,新的价值观的出现和追崇时尚,一些汉语原语词衍生出一种或多种新的意义,并被较为广泛应用,它具有褒贬、造势、烘托、强化等表达功能,增强了汉语的表现力。对应用汉语语汇衍生义我们应持积极科学的态度。     

Krashen与Bialystok二语习得理论比较研究

Krashen和Bialystok的模式是第二语言习得领域提出较早,至今仍有很大影响的理论。在概述其内容后,本文重点分析了两个理论模式的相似、相异之处。相似性分析使两理论得到相互阐释和互相证明,相异分析找出了互补之处,使其有了更强的阐释力,最后探讨了对我国外语教学的启示。     

多语型民族语言习得的特点分析——四川盐源县白家村藏族多语习得的个案研究

少数民族兼用第二种语言有双语型及多语型之分,即有的只兼用一种语言,有的兼用一种或一种以上的语言。多语型的民族在不同语言的习得中特点及规律各不相同。研究表明,多语兼用与民族杂居等自然、社会环境有关;婚姻习惯制约多语兼用的特点;时代和社会的发展变迁也直接影响多语兼用现象的发展趋势。     

Managing Demand Uncertainty through Core Acquisition in Remanufacturing

We discuss the optimal raw material acquisition strategy for a third party remanufacturer (3PR). We specifically investigate whether a 3PR should acquire used products or cores in bulk with uncertain quality levels, or in sorted grades with known quality levels; and whether to acquire and remanufacture cores before the demand is realized (planned acquisition), or after the demand is realized (reactive acquisition), or on both occasions (sequential acquisition). When only sorted cores are acquired, we find that, (i) it is optimal to acquire cores in multiple grades to balance acquisition and remanufacturing costs; (ii) if reactive acquisition is possible, it reduces the assortment size (number of grades in which cores are acquired) and the total inventory acquired in the planned acquisition; and (iii) the optimal portfolio of grades to acquire and the optimal acquisition and remanufacturing quantities of these grades can be determined analytically. When bulk cores are acquired in addition to sorted cores, the property of reduction in assortment size of the planned acquisition is preserved. We also show that the 3PR should acquire only a fraction of the demand in planned acquisition, and leave the rest for reactive acquisition. This fraction changes during the lifecycle of a remanufactured product. Using a combination of empirical and realistic data from a smartphone remanufacturer we show that sequential acquisition increases expected profit by up to 8% and 27% over only planned and only reactive acquisitions respectively, and reduces the inventory acquired by up to 21% over only planned acquisition.
