高职公共英语改革问题探讨

高职公共英语课程是高等职业教育的一个有机组成部分,其目的是为社会培养生产、建设及管理第一线需要的高技能人才,培养学生实际应用语言的技能,特别是用英语处理与未来职业相关的能力。我国的高职、高专英语改革已经步入深化与发展阶段,但仍存在诸多问题,应通过多种对策以促进改革目标的实现。     

基于多媒体网络的大学英语听力元认知策略培训研究——以湖南工程学院为例

以第二语言习得中的元认知策略理论为指导,将现代多媒体网络技术应用于大学英语听力教学实践,并以湖南工程学院两个平行班级为实验对象,对其进行听力策略培训,结果证明它不但能提高他们的英语听力成绩,还能培养策略意识,而这对英语学习至关重要。     

《回回原来》及其相关研究述评

本文对已往学术界对有关《回回原来》的研究作了较为细致的梳理,并将有关研究从方法上分为实证史学研究和民族民间文学研究两类。同时,对两种不同研究策略作了比较和评价。     

“两伊问题”困扰中的美国海湾战略选择

伊战后,美国的海湾战略屡屡受挫,在中东面临危机多元化和扩散化的严重挑战。在伊拉克陷阱和伊朗核问题的双重困扰下,小布什政府及其后任可能的战略选择包括坚持原有“主导和预防行动”、采取“崩溃预防型”、恢复“稳定、威慑和遏制”、考虑“合作型秩序”等。但除非美国放弃独家主导海湾的霸权战略并调整其战略目标,否则难以在“支配”海湾地区和摆脱困境之间找到两全出路。     

The Positive Effects of Easy Goals on Decision Quality and Risk Propensity in an MCPLP Task

In this study the potential performance benefits of easy goals were examined within the multiple cue probability learning paradigm (MCPLP). Specifically, the effects of varying levels of goal difficulty on performance and risk propensity (used to define a form of commitment) were investigated. With few exceptions, previous studies demonstrated support for difficult goals. In this study, contrary to the majority of past evidence, as goals became easier decision quality significantly improved. Moreover, risk propensity increased with easier goals and, as suggested by a post-hoc analysis, had more direct impact on decision makers’ behaviors than goal levels. Goal-related behavior in complex MCPLP tasks appears to significantly differ from the majority of goal evidence in other types of research due to the tendency for subjects to view complex task properties in the same context as goal levels.     

印度对中印跨境河流水关系的认知及战略选择

近年来,印度对中印在跨境河流水关系中的不平衡问题非常重视.其中,水文信息不对称以及收益不平衡是印度对水关系不平衡的两个主要认知.基于中印边境的互动历史,印度在对水关系的认知形成中往往会夸大中国的敌意与威胁.据此,印度试图通过建立制度框架、将中印水争议国际化以及竞争性开发跨境河流水资源的战略思维,平衡中国在雅鲁藏布江—布拉马普特拉河水关系中的优势地位.然而受水外交两面性特征和内政的掣肘,印度平衡战略的影响有限,而且更强化了其对雅鲁藏布江—布拉马普特拉河战略安全收益的重视,并使未来中印双方基于水资源共同利益进行合作的难度加大.     

When Restrictive Constraints Are Nonbinding: Illustrations and Implications

For convex and concave mathematical programs restrictive constraints (i.e., their deletion would change the optimum) will always be binding at the optimum, and vice versa. Less well-known is the fact that this property does not hold more generally, even for problems with convex feasible sets. This paper demonstrates the latter fact using numerical illustrations of common classes of problems. It then discusses the implications for public policy analysis, econometric estimation, and solution algorithms.     

ASSESSING ENVIRONMENTAL SCANNING AT THE SUBUNIT LEVEL: A MULTITRAIT-MULTIMETHOD ANALYSIS*

Environmental scanning activities of over 400 top management subunits in 108 European manufacturing firms provided the data base for this research. Four traits (constructs) of scanning using three methods (interest, frequency, and time) were examined. A confirmatory factor analysis approach to multitrait-multimethod (MTMM) data was employed. Verification of the reliability as well as convergent and discriminant validity of the scanning scales are reported and discussed. The viability of confirmatory factor analysis in providing a precise analysis of partitioning variance according to trait, method, and error is demonstrated.     

DEVIL'S ADVOCACY AND DIALECTICAL INQUIRY EFFECTS ON PREDICTION PERFORMANCE: TASK INVOLVEMENT AS A MEDIATING VARIABLE

Critics of previous laboratory experiments comparing devil's advocacy (DA) to dialectical inquiry (DI) have suggested that these experiments produced misleading results because (1) they used subjects who had low levels of task involvement and (2) the DI treatment used was confusing to subjects and required further explanation to be useful. The present study examines the effects of four inquiry methods—expert (E), DA, DI, and DI with explanatory statement (DI+)—on subjects' performance at a financial prediction task. Results show that DA, DI, and DI + were superior to E when the state of the world differed significantly from assumptions underlying the expert's plan. For subjects with high task involvement, DI and DI + were more effective than E and DA. The results support some of the criticisms of previous laboratory research and suggest that future research on these decision aids should include task involvement as a factor.
