口译专业能力的培养离不开多模态口译教学对视频素材的恰当运用。文章利用眼动仪探究受试在视频字幕模态和无字幕模态条件下认知负荷的变化及其与译文质量的关系。邀请40名受试无笔记交传TED视频。实验证实视频的字幕模态在口译输入时会对受试认知负荷产生影响,字幕模态输入降低受试认知负荷,提升译文表达的流畅性,译文质量更佳。 相似文献

视频生动形象的直观画面深受聋人喜爱,但由于聋人的听力受损,使得聋人对视频的信息处理面临诸多困难,无法有效接收、理解视频内容。为此,文章以聋人的自适应学习需求为导向,确定了包括数据处理、用户定位、字幕匹配和无障碍字幕呈现四个环节的聋人视频无障碍字幕设计流程。同时,文章介绍了两个典型的聋人自适应学习场景:面向聋人的交互式视频资源平台和人工智能技术支持的聋童识字阅读,并分别提出了相适的无障碍字幕设计方案。进行基于自适应学习需求的聋人视频无障碍字幕设计,不仅有利于提升聋人的学习兴趣并有效、完整地接收视频信息,而且在一定程度上促进了聋人的教育公平。 相似文献

文章从学习认知和学习满意度层面,通过实验测量了学习者对四种呈现方式的教学视频进行自主学习的效果。研究结果表明:在学习认知方面,A(视频类+解说字幕)组别的教学视频学习成绩最好,有解说字幕比无解说字幕的教学视频学习成绩好;在学习满意度方面,视频类教学视频比图文类教学视频的学习满意度高。并在此实验结果的基础上,从教学视频资源建设和基于教学视频的自主学习层面提出了建议。 相似文献

介绍了视频字幕翻译功能、文本特点。在此基础上,提出视频字幕翻译作为一种特殊类型的翻译,其翻译不仅与文本内容紧密相关,还与视频字幕技术和视觉感受相关,需要借助数字媒体技术将其合理展现,让其可视性凸显出来。进行视频字幕翻译时,译者需要将技术层面的策略与文本层面的策略相结合,结合使用多种翻译技巧,提高视频字幕的翻译质量。 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献
