Communicating Knowing Through Communities of Practice: Exploring Internal Communicative Processes and Differences Among CoPs

Knowing is an enacted, communicated process that is difficult to observe, let alone manage, in organizations. Communities of practice (CoPs) offer a productive solution for improving knowledge and knowledge management, but the communicative processes that enact CoPs have not been explored, leaving CoPs as an organizational black box. This research extends CoP theory as a means to determine the presence of a CoP and distinguish between various CoPs, and as a practical means to evaluate the communicative processes of organizational knowledge. CoPs enact the communicative nature of knowing through the elements of mutual engagement, negotiation of a joint enterprise, and shared repertoire. Specifically, two groups of volunteers are examined through a combination of participation, observation, and interviews in order to explore CoP theory as a dynamic system for examining and evaluating organizational knowledge.

Establishing the structure of reality for an industry: model and anti-model arguments as advocacy in Nike's crisis communication

This study illustrates the potential role of model and anti-model arguments in organizational crisis communication. Specifically, model and anti-model arguments are described as a strategy for moving the focus of a crisis from an organization to its industry. Model arguments enable organizations to establish their corrective action as industry standards that merit imitation. Conversely, organizations can set minimum standards for their industries with anti-model arguments. Phil Knight's May 12, 1998, speech announcing Nike's new initiatives in global manufacturing is analyzed as a case study. The essay concludes that model and anti-model arguments can suspend criticism of the organization, create the foundation for a return to industry prominence by the organization, and establish proposed new industry standards that are favorable to the organization.     

Teacher e-mail message strategies and students' willingness to communicate online

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers.

Domesticating Computers and the Internet

The people who use computers and the ways they use them have changed substantially over the past 25 years. In the beginning highly educated people, mostly men, in technical professions used computers for work, but over time a much broader range of people are using computers for personal and domestic purposes. This trend is still continuing, and over a shorter time scale has been replicated with the use of the Internet. This paper uses data from four national surveys to document how personal computers and the Internet have become increasingly domesticated since 1995 and to explore the mechanisms for this shift. Now people log on more often from home than from places of employment and do so for pleasure and for personal purposes rather than for their jobs. Analyses comparing veteran Internet users to novices in 1998 and 2000 and analyses comparing the change in use within a single sample between 1995 and 1996 support two complementary explanations for how these technologies have become domesticated. Women, children, and less well-educated individuals are increasingly using computers and the Internet and have a more personal set of motives than well-educated men. In addition, the widespread diffusion of the PC and the Internet and the response of the computing industry to the diversity in consumers has led to a rich set of personal and domestic services.     

基于LabVIEW串行通信系统的开发

虚拟仪器是由软件实现的．其软件开发平台是LabVIEW。VISA是在所有LabVIEW工作平台上控制VISA、GPIB、RS-232以及其他种类仪器的单接口程序库，通过LabVIEW平台中的VISA模块编写控制程序，可以进行仪器控制。本文以串行通信为例．用LabVIEW构建仪器控制进行串行设备通信．在虚拟环境中使用VISA功能模块向串行设备读写数据，缩短了项目开发周期，提高了开发效率。     

被遗忘的中国早期传播研究——评朱希祖的《道家与法家对于交通机关相反之意见》

1925年民国时期历史学家朱希祖在《北京大学社会科学季刊》上发表了《道家与法家对于交通机关相反之意见》一文,将社会传播手段分为物质交通机关和精神交通机关两种,并对道家反对传播、法家主张利用和发展传播的原因进行了深入分析。这是目前所见的中国学者关于传播问题的最早专门论述之一。
