Guided by rhetorical/relational goal theory, the purpose of this study was to examine whether students’ impressions of their instructors’ credibility, attraction, and homophily are influenced by four specific rhetorical and relational communication behaviors that instructors use when communicating with their students in the classroom. Participants were 193 undergraduate students enrolled in a variety of introductory communication courses at a large mid-Atlantic university. Using a series of multiple regression analyses, it was found that (a) clarity emerged as the sole indicator of instructor competence, trustworthiness, and task attraction; (b) clarity and confirmation emerged as indicators of goodwill; and (c) humor and confirmation emerged as indicators of social attraction and attitude homophily. 相似文献

麦克卢汉的媒介冷热论一直困扰着学界。因为笼统地从信息清晰度和受众心理参与程度考察,往往得出相反的结论,形成媒介冷热悖论。笔者从抽象数据清晰度和具象数据清晰度两个维度对清晰度性质进行甄别,从感知参与和思维参与两个维度对心理参与性质进行区分,揭示悖论产生的原因,对清晰度与心理参与的相关性进行了重新审视,并对不同媒介的冷、热属性进行了具体分析。 相似文献

This study used panel data to examine attitudes of U. S. residents toward the Soviet Union during the onset of a thaw in relations between the superpowers in the mid 1980s. It hypothesized that increased consumption of world news would covary with more‐favorable changes in such attitudes. Data analyses corroborated the prediction. 相似文献

The growth of the Internet has created a host of thorny legal issues that range from defamatory postings on computer bulletin boards to “spamming”; (unwanted email) and invasion of privacy rights. This study reviewed 400 student‐authored World Wide Web pages to assess the use of intellectual property. A review of these pages found that 43.8 percent appropriated images that would likely qualify as protected intellectual property, and that the students who used images averaged three such uses per page. The final section briefly discusses three of the more troublesome implications of these findings. 相似文献

浅析增词法在英汉翻译中的应用 总被引：1，自引：0，他引：1
谢欣欣 《福建师大福清分校学报》2003,(Z1):141-145
翻译是用目的语把源语言的信息传达出来的过程.其标准是"忠实"、"通顺",为了达到这一标准,在翻译过程中就必须掌握一定的方法,增词法就是较常用的一种.所谓"增词",就是在翻译中添加一些必要的词汇,使译文的意思更清楚明了.当然也不能离开原文随便增加词汇,而应该遵循一定的规则.经过分析总结,本人认为基本上可以从词汇、语法、逻辑、修辞、和谚语等几方面进行适当的增补. 相似文献
