“四体联动”应对反倾销的信息沟通机制研究

国外对我出口企业提起反倾销诉讼案件不断,造成了严重的市场萎缩和巨大的经济损失。目前企业对反倾销的应诉积极性不够,胜诉率不高,原因之一是信息沟通机制不健全。在信息沟通过程中企业单方面的力量是不够的．应该协同商务部、地方政府和行业商协会建立健全反倾销的信息沟通机制。四体各司其职,联动协作,理解信息沟通的重要性,畅通沟通渠道,完善反馈机制,才能提高“四体联动”应对反倾销的事前防范和事中应对能力。

跨文化交际中的时间观念差异及对策

时间作为一种无声的语言,文化的一个重要部分,在我们日常的生活中扮演着非常重要的作用,而作为文化的差异必然带来时间观念的冲突,时间观念的冲突又反过影响着不同文化人们之间的正常交往。因此分析不同的社会之间,不同的文明之间,以及处在不同的文化中的人们在跨文化交际出现的时间观念的差异和冲突具有重要的现实意义。本文主要就美国人类学家爱德华霍尔的时间存在理论和美国人类学家-克拉克洪与斯乔贝克的时间导向理论对中国,美国和古巴三国的时间价值观进行对比研究,从而更好地对一些跨国外企以及跨文化工作者提供理论和现实参考。     

利用多媒体促进英语文化教学的“折中”,发挥母语正迁移作用

当前英语教学中的文化教学对目标语文化过分重视,而对母语文化重视不够。外语教学所表现出的"折中主义"为语言教学提供了一个新的发展方向,因而文化教学在母语与目标语之间呈现"折中"是必然的。英语教学中有效利用多媒体能促进英语文化教学的"折中",发挥母语正迁移作用。     

论公示语文本规范化及其交际翻译原则

探讨了现代公示语的文本规范化问题,及其文本属性和应用功能,并以交际翻译原则为理论依托,阐释了公示语英译问题诸方面,认为翻译公示语应首先追问原文规范化程度如何,只有将其与翻译策略研究同时并举,才有利于公示语双语化实现其原本交际功能和意图。     

Experientially learning how to communicate science effectively: A case study on decoding science

The need for science communication programs is matched with the need for program evaluation. This case study is an evaluation of the “Decoding Science” program (DSP) [Rodgers et al. (2018). Science Communication, 40(1), 3–32], a science communication training program, and examines key experiential-learning themes [Kolb, D. A. (1984). Experiential learning: Experience as the source of learning and development. Englewood Cliffs, NJ: Prentice-Hall]. Specifically, we discuss the program's emphasis on learning that science communication is a process that (a) is continual, (b) involves conflict resolution, (c) requires adaptation to the world, (d) requires environmental interaction, and leads to (e) knowledge creation. Additionally, we discuss our analysis of student feedback. Results suggest that the DSP successfully utilizes experiential learning to facilitate the learning of science communication techniques and that future evaluations can lead to the development and improvement of science communication training programs.

Cultivating Students’ Cultural Awareness inEnglish Teaching

With the fast development of Chinese economy and society,the communication between China and foreign countries has been more and more frequent.And China is a country where English is taught as a foreign language.Therefore cultural differences have become more and more significant in English teaching.Both language teachers and students should be aware of the differences between eastern and western culture in their teaching and study.     

Using a concept mapping strategy to improve the motivation of EFL students in Google Hangouts Peer-Tutoring Sessions with native speakers

This study examines four elements of learner motivation, attention, relevance, confidence, and satisfaction, in an EFL speaking course that uses the computer mediated communication (CMC) tool Google Hangouts. The study found that a preparatory concept mapping task before the CMC sessions improved students’ perceived attention, relevance, confidence, and satisfaction. However, follow-up reflective worksheets had no effect on perceived attention, relevance, confidence, or satisfaction. Instructors should use concept mapping in a pre-task to support learners engaged in CMC-based speaking activities with native and non-native speakers. When the students used concept mapping to prepare for the CMC-based speaking activities, they exhibited higher confidence in their oral practice activities with a native speaker.
