基于光滑互补函数,将非线性互补问题等价转化光滑方程组问题,构造了一个新的求解该光滑方程组的非精确 Jacobian 光滑化方法,该算法克服牛顿法解大规模互补问题的不便,并证明了该算法具有全局收敛性,在一定的假设条件下具有局部二次收敛性。     

Fairclough三维分析模型下的新闻话语分析——以CNN和马航官网关于马航失联飞机的新闻报道为例

以CNN和马航官网报道马航失联航班MH370的新闻为话语分析语料,借鉴Fairclough的批评话语三维分析模型,以及在此基础上拓展的理论框架,通过对比、分析语料在描述、解释和阐释等方面的不同及其所反映的国家统治阶级意识形态差异,帮助人们提高对新闻话语的敏感性,提高批判性阅读与信息接收的能力。     

基于Wmatrix的政府工作报告外宣中中央政府形象研究

本研究使用线上语料库工具Wmatrix3,将语料库的自动语义标注方法与批评话语分析的话语历史方法(DHA)相结合,考察了2014-2018年国务院《政府工作报告》外宣中建构中央政府形象的建构策略。研究发现,报告外宣通过命名策略、述谓策略和论辩策略塑造出中央政府亲民而权威的群内主体,彰显其为民服务、实干、简朴和负责的形象,突出其坚定建设法治政府和廉洁政府的决心。此种群内形象的建构源自报告英译的政治诉求和报告外宣的最终目的。本研究充分显示了基于自动语义标注的DHA分析是考察形象建构的有效工具。     

基于SIOP模式的大学英语教学对本科生批判性思维影响的实证研究

SIOP模式是“语言学习与应用能力相结合”､“学科知识与思维发展相结合”的教学模式,它为语言知识的学习和思维能力的培养提供了可行性途径。本研究以语言类课程——大学英语为依托,选取某省属 重点大学一年级157名学生,分为实验班和控制班,分别采用 SIOP 模式和传统模式教学。一学年之后,两班 前后测结果说明,SIOP 教学模式对大学英语学习者批判性思维能力的提升具有积极的促进作用。该研究结果对 SIOP 教学模式的本土化应用以及我国本科生批判性思维的培养具有一定的启示和参考价值。     

混合CD-DY共轭梯度法

在CD方法和DY方法的基础上对求解无约束优化问题提出了一种混合的CD-DY共轭梯度法.在广义Wolfe线搜索下无需给定下降条件,即可证明混合方法的全局收敛性.初步试验表明新方法的数值效果优于CD方法和DY方法.     

全球正义：内涵、框架及限度

分析了全球正义的内涵、适用框架及其限度等问题,指出在全球化时代,全球正义不仅是一个重要的理论问题还是一个重要的实践问题,相较于传统的正义观研究,全球正义问题是在跨国的层面展现的,它不仅具有一般正义问题的共性还有其内在的规定性.全球正义不仅仅是传统正义在跨国层面的延伸,在全球主权无法成立的条件下,对全球正义的呼唤也是突破不公正、不合理的国际政治、经济旧秩序的客观诉求,更是对当下世界贫富分化日益严重的理论应答.

The role of English language and international media as agents of cultural globalisation and their impact on identity formation in Kuwait

This study examines the influence of English language usage and international media on the strength of either national or global identity. The regression analysis of 354 responses reveals that individuals who studied at universities that use English as a medium of instruction show significant differences in the extent to which they embrace a global identity. Viewing local (Kuwaiti) television programmes and the use of the Internet predict national identity. This study discusses the social entities that are important factors in mitigating the influence of globalisation on national identity. It concludes that the argument that globalisation and Westernisation are two faces of the same coin is overstated.     

Critical Discourse Analysis： A Theoretical Framework for Analyzing Mathematics Teaching in Multilingual Classrooms？

The purpose of this article is to develop a framework that can be used to describe and explain how mathematics teachers construct a multilingual classroom and the discourse practices being produced in a mathematics classroom. It conceptualizes the discourse practices used by mathematics teacher educators as they prepare student teachers to teach mathematics. The framework developed here is shaped by Critical Discourse Analysis （CDA） drawn from Fairclough. This provides the theoretical and conceptual tools to examine the discourse practices of mathematics teacher educators and how the）＇ make available these discourse practices for student teachers to draw on. In broad terms, this article examines the discourse practices of the mathematics teacher educators and how they support the student teachers develop discourse practices relevant for teaching and learning school mathematics in multilingual classrooms. This article is broken down into several sections. The first section discusses what it means for student teachers to develop discourse practices for mathematics teaching. The second section provides an introduction to CDA, followed by its origins, key terms, and elements of Fairclough＇s CDA. Thereafter, the author outlines the strategies involved in doing CDA. The last section discusses why CDA is relevant to the mathematics classroom.     

Toppling hierarchies? Media and information literacies,ethnicity, and performative media practices

This article suggests how we should study media and information literacies (MIL) and do so at a time, when young people nurture these literacies through multiple media practices and across spaces of learning. Our basic argument is this: in order to gain a robust knowledge base for the development of MIL we need to study literacy practices beyond print literacy and numeracy, and we need to study these practices beyond formal spaces of learning. The argument is unfolded with particular focus on ethnic minority youth since this group routinely figures as under-achieving in studies of school literacy, such as Programme for International Student Assessment. Based on a brief overview of literacy studies in view of digitization and a critical examination of recent studies of youthful media practices and ethnicity, the argument is illustrated through an empirical analysis that draws on results from a nationally representative survey of media uses among Danes aged 13–23 years. The analysis demonstrates that ethnic minority youth offer the most serious challenge to existing literacy hierarchies found in formal education. We discuss the implications of these results for educational policy-making and for future research on MIL, advocating inclusive approaches in terms of media for learning and spaces of learning.
