Based on the social network perspective and work group perspective, this study brings social interaction tie and membership esteem together as the mediating variables between knowledge contribution and social identity to construct an inductive route model, aiming to understand how social identity and self-identity form based on knowledge contribution behaviors in virtual communities. To assess ...

This paper presents the theoretical framework for a project in which we will design, develop and test a personal identity profile that can contribute to an improved mediated collaboration environment for virtual project teams. The profile aims to foster interpersonal trust by enabling better and quicker estimations on trustworthiness. We here describe the mental model for trustworthiness estima...

We present a new approach to the design, development and evaluation of embodied conversational agents (ECAs) that allows them to index identity through culturally and socially authentic verbal and non-verbal behaviors. This approach is illustrated with research we are carrying out with children who speak several dialects of American English, and the subsequent implementation and first evaluatio...

Blockchain is one of several technologies du jour. It combines clever methods from peer-to-peer decentralized computing to provide an online tracing function for virtual transactions, and, once someone sets it up, it requires minimal intervention from a central auditor. While Bitcoin is the most well-known application of this innovative computer science, verification of authenticity and identit...

This paper provides an overview of virtual teams in the information age, focussing on the definition of virtual teams, their salient characteristics, the communication issues they face (including information overload, geographic and social distance), the technical issues involved (linking this to theories of media use), the issues raised by cultural diversity in the teams (including identity, t...

Chris Kimble Abstract This article explores some of the challenges faced when managing virtual teams, in particular the role played by trust and identity in virtual teams. It outlines why teams and virtual teams have become a valuable part of the modern organization and presents ten short case studies that illustrate the range of activities in which virtual teams can be found. Following this, t...

This research examines how the provision of virtual team membership consistency may impact perceptions of the communication technology and interactions as well as performance. The results from a repeated measures experiment finds that virtual teams with expectations of inconsistency in membership have a more negative perception of the supporting technology, and perceive less coordination than c...

This article examined the feasibility of a computer-based program that alleviates the human resource challenge associated with blind photoarrays (photoarrays in which the investigator is blind to the suspect’s identity). Students watched videotaped crimes and attempted to identify the perpetrators from photoarays conducted by a “virtual officer” who responds to simple voice commands or by resea...

Most existing 3D virtual worlds are based on a ”meeting-space”model, conceived as an extension of textual chat systems. An attractive 3D interface is assumed to be sufficient to encourage the emergence of a community. We look at some alternative models of virtual communities, and explore the issue of promoting community formation in a 3D meeting space. We identify some essential or desirable fe...

This paper considers the problem of distributing data and code among the processors of a distributed memory supercomputer. Provided that the source program is amenable to detailed dataaow analysis, one may determine a placement function by an algorithm analogous to Gaussian elimination. Such a function completely characterizes the distribution by giving the identity of the virtual processor on ...
