摘要:

Computer‐mediated communication (CMC) has been described as lacking nonverbal cues, which affects the nature of interpersonal interaction via the medium. Yet much CMC conveys nonverbal cues in terms of chronemics, or time‐related messages. Different uses of time signals in electronic mail were hypothesized to affect interpersonal perceptions of CMC senders and respondents. An experiment altered the time stamps in replicated e‐mail messages in order to assess two time variations: (a) the time of day a message was sent and (b) the time lag until a reply was received. Results revealed significant interactions among these variables, and the task‐orientation or socioemotional orientation of the verbal messages, which affected perceptions of communicators’ intimacy/liking or dominance/submissiveness. Findings extend recent theories regarding social attributions and the adaptation of social cues in CMC behavior.

摘要:

When multiple people are involved in designing an information systems application, there can be conflicts in terminologies used by them for various elements represented in the application. These problems are recognized in database design, federated databases, knowledge‐based systems, mathematical modeling systems, and cooperative work systems. A computer‐based method for detecting such naming conflicts, once the users have declared certain additional information for all of the represented elements, is presented. The approach extends earlier work by Bhargava, Kimbrough, and Krishnan in the context of model integration. There is a description of how this additional information (calledquiddity)is to be formulated and represented, and several automated procedures are presented that detect naming conflicts on the basis of this information. The practical utility of this approach is also discussed.

摘要:

Vascular medicine is a newly developing discipline heavily based on geographically distributed consulting, and there is thus a strong need for computerized decision support in doctor‐to‐doctor collaboration for the management of vascular patients. The latest achievements in collaborative and multimedia computing for group decision support are incorporated into cardiovascular consulting. Feasibility analysis of the two basic components is addressed: (a) the communication system of collaborative computing as identified subject to the specifics of data flow and networking in geographically distributed cardiovascular consulting; and (b) the structure and representations for intelligent software agents that enable transfer of individual expert cardiovascular knowledge, support group brainstorming, and maintain the ongoing learning of group experience and analysis of patients cases.

摘要:

Internet applications such as the World Wide Web (WWW) have created the possibility of developing global collaborative platforms for supporting interactions between professionals and academics in various disciplines. While Web browsers such as Mosaic and Netscape have revolutionized the way we use the Internet, we envision the need for a theory‐based approach to the development of Collaboratories on the Internet. Based on complementarity theory, we provide a conceptual foundation for designing Collaboratories which maximize users’ value through the judicious choice of complementary design factors. We emphasize the need for developments in the area of “open”; collaborative systems, and suggest that analyzing the design problem from a complementarity theory standpoint can lead to useful insights regarding the value users derive from the system. We also describe the design and an early implementation of an MIS Collaboratory, which uses this theoretical foundation to organize information and to provide a forum for document‐centric, multimedia interactions between users. While the prototype focuses on the MIS discipline, we believe that the general principles of our design are applicable to other areas as well.
