一种用于车载电磁兼容设计的无线信道频率优选算法

针对车载通信系统中多个无线通信设备同时工作导致的电磁干扰问题,论文通过分析发射机的基本频率、谐波频率和接收机受损频带之间的关系,提出一种优选工作频率的算法。实例测试与理论分析结果表明该算法可以保证系统的整体通信性能,并有效提升高负载频谱系统的电磁兼容指标。     

浅析非正式交流的历史变迁

随着科学的发展和网络的兴起,非正式交流发生了巨大的变化。文章分别从定义、交流手段、交流模式等方面对传统的和基于网络的非正式交流作了总结,并在此基础上分析了它们之间的共性和差异。文章认为,作为科学交流系统的重要组成部分,网络非正式交流的全新交流模式克服了传统交流的弊端,更好地适应了科学大发展的需要,然而,它并不能完全取代传统非正式交流,二者将长期共存,共同为科学发展服务。     

Negative side effects of music listening during cross-cultural transitions: Exploring how music hinders cross-cultural (re)adaptation among student sojourners

Although media use has been shown to have benefits in many contexts, including study abroad, it may also hinder cross-cultural transitions in academic sojourns. This study examines how music (as a form of communication media) may interfere with adaptation to the host culture and readaptation to the home culture. Focus groups and interviews with a total of 23 college students (twelve U.S. students and eleven international students) revealed that music hindered sojourners’ ability to interact in social settings, as well as amplified negative feelings while abroad and during reentry. Participants experienced these temporary side effects in conjunction with (or as part of) their purposeful and functional use of music to escape from the social environment and alleviate negative emotions.

交际的非言语途径

话语是用来交际的。参加交流各方不断发出信息,期待对方做出某种反应。话语的这个作用大大地扩大了话语分析的范围,因此话语分析要探索话语语言是如何与语言本身保持间接(甚至是相矛盾的)关系的。     

天文馆的科学传播与旅游体验——墨西哥科苏梅尔天文馆

科苏梅尔天文馆是墨西哥金塔纳罗奥州四座天文馆之一,位于加勒比海中的科苏梅尔岛上。科苏梅尔岛作为旅游胜地,每年都会接待无数慕名而来的游客。当地丰富而独具特色的旅游资源为天文馆的发展带来了机遇与挑战。在发达的旅游业氛围中,科苏梅尔天文馆的目标不仅限于服务当地公众,也期望吸引更多外国游客。科苏梅尔天文馆采取的一系列的措施,使其不仅成为了岛内的教育中心,同时也成为了游客们向往的观光目标。     

个体主义与集体主义——多元视角下中西方文化对比

价值观差异是影响跨文化交际的一个重要因素,其中集体主义与个体主义的差异体现在方方面面,表现尤为明显。本文从文学影视、生活方式、家庭观念、教育方式、饮食习惯等多个视角分析了中西方集体主义与个体主义的不同表现形式,指出研究价值观差异,尤其是集体主义与个体主义是促进跨文化交际顺利进行的重要方法。     

非语言交际在高中英语课堂教学中的应用

非语言交际在人类交际活动中起着不可忽视的作用,英语课堂教学的成败与非语言交际运用的关系密切.在高中英语课堂教学中,非语言交际手段的恰当运用传递了丰富的信息,促进了英语良好的交流与沟通.     

Evaluation of small‐group teaching in human gross anatomy in a Caribbean medical school

Although there are a number of medical schools in the Caribbean islands, very few reports have come out so far in the literature regarding the efficacy of small‐group teaching in them. The introduction of small‐group teaching in the gross anatomy laboratory one and a half years ago at St. Matthew's University (SMU) on Grand Cayman appears to have had a significant positive impact on the academic achievement of students in anatomy. This study surveyed the responses of the students to the small‐group learning method in gross anatomy at SMU using a structured questionnaire. The results show that our students prefer this small‐group learning method over a completely self‐directed method in the gross anatomy lab because the study materials were carefully chosen and the study objectives were demonstrated by the resource person. However, teacher‐centered teaching was deliberately avoided by fostering problem‐solving skills in the anatomy lab sessions. Another aim of the small‐group teaching at SMU was to develop the interpersonal and communication skills of the students, which are important in their later education and career.

大学英语跨文化交际能力培养体系研究与实践

随着全球化的深入和信息技术的广泛运用,国际交往对人才培养提出了更高的要求。国家教育改革也对大学英语教学改革提出了新的要求。本文结合笔者所在大学在跨文化交际能力培养方面的实践,对大学英语教学体系进行了实践性研究,提出了大学英语跨文化交际能力培养四大目标:语言能力、思维能力、行为能力和社会性发展能力。并据此构建了新的大学英语培养体系:培养目标、教学理念与教师主体、培养方法和手段、教学环境。在这四部分中,第一部分是行动依据和指南,第二部分是关键和保障,第三部分是实现目标的方法,第四部分是外在环境。四者之间互为关联,构成一个完整的体系。
