挖掘记载科学知识的交叉领域文献,可以探究交叉领域形成和发展中的知识流动和知识创造规律。本文依据词汇在交叉领域文献中的位置功能,提出了“文献空间观”和交叉领域知识生长过程模型,包括知识吸纳、知识内化和知识创新三大环节,进而构建一种全文本分析方法框架实现对交叉领域知识生长过程的量化分析。以生物信息学领域作为案例开展了实证分析,研究结果发现,知识内化与知识吸纳高度相关,数量差距约6倍,但变化趋势相同;领域知识创新第一次高峰出现时间晚于知识吸纳和内化4年左右;随着学科不断成熟,即时内化率保持相对稳定,总内化率降低,新增吸纳知识的内化时滞降低,内化知识激发知识创新的效率越来越高。本文所提出的面向交叉领域知识生长的全文本分析方法框架,能够丰富学术文献全文本内容分析方法体系。 相似文献

Expression and Reception: An Analytic Method for Assessing Message Production and Consumption in CMC
Kang Namkoong Dhavan V. Shah Bryan McLaughlin Ming-Yuan Chih Tae Joon Moon Shawnika Hull 《Communication methods and measures》2017,11(3):153-172
This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks. 相似文献

This study examines how communication related anxieties are related to individuals' use of computer mediated communication (CMC). 225 respondents were given the PRCA‐24, WAT, and RAT tests. They were also given a measure of computer anxiety. Respondents were then asked to indicate the extent to which they used e‐mail, interactive messaging, or web browsers. The results indicate that there is no relationship between communication anxieties and CMC use. Computer anxiety appears to be the main predictor of e‐mail, chat, and web use. 相似文献

This study investigated how the interpersonal traits of communication apprehension (CA) and interaction involvement (II) are related to one's attitudes toward and use of computer‐mediated communication (CMC). Data were collected by administering a self‐report survey to a sample of 133 participants, and results were analyzed with multiple regression. Findings revealed that CA and II failed to predict CMC attitudes. However, each trait predicted communication style during online interaction. Findings are interpreted within the context of current theories of CMC. 相似文献

ABSTRACTThe hyperpersonal communication model was used to investigate the implications of the reduced social cues in computer-mediated communication (CMC) for the production of social support messages. Participants were randomly assigned to interact with a confederate seeking help about a problem for which the confederate was or was not responsible. The interactions took place either face-to-face or in one of two CMC conditions. The results were partially consistent with the intensification effect proposed in the hyperpersonal model. Participants evaluated the confederate most negatively, but produced the highest quality support messages, in the CMC condition with visual anonymity followed by the CMC condition and face-to-face condition. Participants’ evaluations of the confederate were also influenced by the confederate’s responsibility for their problem. 相似文献

This article presents a content analysis of three computer‐mediated communication (CMC) networks used for political discussion during the 1992 Presidential election campaign. Data indicate that the main use of computer networks in the campaign was to assert personal opinions about the candidates, issues, and the election. Other uses were talking about one's own life and experiences, telling others what they should be doing, and posting information for others to read. Significant differences were found between the three campaigns for uses of these computer networks. The Clinton network was used more than the other two for posting information. The Perot network was used more than the others for asserting opinions. This study indicates that voters have specific functions for the use of computer networks as new channels of political communication. Future research should examine what groups of voters use these networks the most and how such use affects candidate image formation. Suggestions are offered for the study of campaign computer lists in the upcoming presidential election of 1996. 相似文献

From birth to death, many individuals chronicle their lives online through blogs, pictures, games, Web sites, and social networks. Online spaces, created by the living about the dead, provide a glimpse into often invisible or silent grieving practices. To investigate the role computer-mediated communication (CMC) plays in influencing communication surrounding the often private and taboo topic of suicide, we analyzed the comments sections of MyDeathSpace.com. Our results suggest both a breaking down of social taboos (speaking ill of the dead) and a reaffirming of strict social norms (enforcing a narrow range of acceptable presentation of identity and purpose in life), highlighting how anonymity as a characteristic of CMC can influence our online communication about death. 相似文献

Summary Instant messaging (IM) reference is gaining in popularity but still faces resistance. Some librarians agree with some researchers in the field of computer-mediated communications (CMC) that it can never approach the complexity of face-to-face communication, and is therefore an unsuitable medium for reference. Librarians in face-to-face reference use nonverbal communication skills such as a welcoming expression and an interested tone of voice to encourage patrons to approach the desk and discuss their topic; they also interpret the nonverbal cues of patrons. This analysis of online reference conversations shows how online skills can substitute for many of these nonverbal cues. Some skills are unique to computer-mediated communication while others involve written language skills to encourage exploration of the topic, increase clarity, demonstrate approachability and empathy, and instruct. The study illustrates communication problems and solutions using actual conversations, giving particular attention to the reference interview. 相似文献

Commonly recognized computer-mediated communication (CMC) tools include virtual environments, bibliographic databases, listservers, newsgroups, group teleconferencing, interactive messaging systems and electronic mail. The use of these technologies in libraries has grown exponentially over the past decade. Electronic mail has emerged as an especially popular communication tool for librarians, and their colleagues and patrons. This paper explores the use of a reference department electronic mail service and its impact on reference services and librarian-client interactions. Several issues related to the implementation of CMC technologies are presented, including the maintenance and monitoring of reference electronic mail systems, the types of questions that are typically posted, and potential barriers to the implementation and use of reference e-mail. 相似文献
