The association between immediacy and socio‐communicative style

The very strong association of immediacy with positive instructional outcomes has led some to question whether teacher immediacy amounts to anything more than being responsive with students. The present study demonstrates that a measure of teacher immediacy is strongly associated with the Socio‐Communicative Style of the teacher—both the assertiveness and the responsiveness components. It is concluded that it is theoretically justified to teach pre‐service or in‐service teachers to engage in immediate behaviors as means of increasing their communication competence and probably teaching effectiveness. The impact of immediacy observed in the classroom environment is seen as likely to be generalizable to other communication contexts.     

Syntactic Indeterminacy,Perceived Message Sensation Value-Enhancing Features,and Message Processing in the Context of Anti-Tobacco Advertisements An earlier version of this manuscript was presented at the 2004 National Communication Association Annual Convention in Chicago,IL, November 11–14, 2004

Fast-paced and arousing anti-drug ads, considered to have high perceived message sensation value (PMSV), enhance message processing and reduce drug use among young adults. Studies have yet to explore the relationship between specific, PMSV-enhancing message features and outcomes related to persuasion. Messaris’ (1997) concept of syntactic indeterminacy provides one plausible explanation for why message features contained in high PMSV ads might enhance message processing and subsequent changes in attitudes and behavior. The study explored this explanation by coding specific anti-tobacco ads for PMSV-enhancing features, merging these codes to a telephone survey among teens, and testing the relationship between message features and processing. The number of unrelated cuts and the use of suspenseful features (intense imagery and a second-half punch) increased message processing among older teens. An additive index comprised of these features was associated with message processing among both younger and older teens. Theoretical and practical implications are discussed.     

The relative effects of timing of suspicion and outcome involvement on biased message processing

The propensity to believe information to be predominately truthful has been called the truth-bias (e.g., McCornack & Levine, 1990), although the lie-bias is the tendency to believe that information is mostly false. The purpose of the current study is to investigate the effect that timing of suspicion and outcome involvement has on biased message processing. A two-way interaction between timing of suspicion and outcome involvement is hypothesized. Specifically, suspicion induced prior to communication will make receivers more suspicious of the communicator and therefore encode more of their nonverbal cues as “suspicious” or “fishy.” This effect is predicted to be magnified in conditions of high outcome involvement. If receivers are already suspicious, and carefully scrutinizing the message, it will be likely that they will note more “fishy behaviors” and demonstrate a heightened lie-bias. In two studies, Participants (Ps) were asked to view videotaped segments of a confederate making true or false statements. The Ps were induced to feel suspicious before or after viewing the videotaped interview. They were also induced to perceive high or low levels of outcome involvement. Results of Study 1 indicated that timing of suspicion has little effect on biased processing, but perceived suspicion did influence biased processing. Results of Study 2 indicated that the timing of suspicion did influence the strength of the truth-bias but did not create a lie-bias. Both studies demonstrated the strong effect of perceived outcome involvement on honesty perceptions.     

Supervisor Impression Management: Message Content and Channel Effects on Impressions

The current study focuses on the delivery of negative feedback and how supervisors can accomplish that delivery while maintaining their own image and their employees' face. We look at delivery of feedback with and without face-saving messages through two different channels: face-to-face (FtF) and email. Results indicate that the inclusion of face-saving messages had relatively consistent positive effects on a variety of employees' impressions of supervisors. Channel was found to interact with message content to impact perceived face threat of a message and the perception of the supervisor's appropriateness. These findings are discussed in terms of theoretical and practical applications, as are limitations and directions for future research.

信息资源共建共享模式及其理论基础研究

通过分析国内外主要的信息资源共建模式,比较其特点和服务功能,从人类文化学的角度,针对现存信息资源共建模式的不足,借鉴费孝通先生的“文化自觉论”,试图从理论和实践两封面论述“文化自觉论”作为网络环境下信息资源共建理论的必要性和可行性,为寻求更合理的信息资源共建模式提供参考和理论依据。     

涵化理论的新进展:作为方法论的直觉加工模型

直觉加工模型是涵化理论的最新发展成果之一,然而这一成果并未得到国内学界的足够关注。本文首先对涵化理论的基本主张及其缺陷进行简要的回顾,并以此为基础对施拉姆(L.J.Shrum)等人于2002年提出的直觉加工模型进行介绍。我们还进一步分析了该模型的心理学假设,并结合现有心理学研究成果分析了有可能导致该模型发挥效用的多个关键因素以及其运用前景。最后,我们在此基础上提出了一系列尚待实证研究探讨并回答的问题。     

联盟型图书馆构成要素及资源共享模式研究

本文首先分析了联盟型图书馆资源共享体系的构成要素,然后分别针对现阶段图书馆方主导型资源共享的主要实现模式SOA,与用户方主导型资源共享的主要实现模式WEB 2.0,进行了深入研究,并指出这两种模式之间具有很强的互补性,最后提出了一种基于SOA/WEB 2.0融合的图书馆资源共享新架构,为该领域的研究提供了一种新的思路。

大档案概念的若干观点简评

本文对“大档案”概念的一些观点进行了评析,笔者认为“大档案”概念有其产生的合理性,在“大档案”概念具有多种内涵的情况下,从专业术语规范的角度看,应尽量避免使用“大档案”概念的提法,而采用较为规范、正式的专业术语。
