The success of chat in this setting suggests a critical re-examination and extension of Clark and Brennan's work on grounding in communication. Specifically, it is argued that there are some settings characterized by reduced information and clarification needs, where the use of extremely lightweight tools (such as basic text chat) can be sufficient for achieving common ground – even when conversational participants are unknown to each other. Theoretical and design implications are then presented.Wed Oct 03 13:46:10 CEST 2007Washington DCPerspectives on Socially Shared Cognition127--149Grounding in communication1991common-ground, grounding Wed Oct 03 13:46:10 CEST 2007GreenwichResearch in Organizational Behaviour191--233Information Richness: A New Approach to Managerial Behaviour and Organizational Design61984media-richness Wed Oct 03 13:46:10 CEST 2007Internet Computing, IEEE582--89Streaming XML with Jabber/XMPP92005icse_exp_report_06, xmpp Jabber is an open alternative to closed instant messaging (IM) and presence services. At its core is the extensible messaging and presence protocol (XMPP), which defines how to stream XML content and is being used to build not only a large open IM network but also a wide range of XML applications. This article provides an overview of Jabber/XMPP protocols and technologies, as well as an introduction to XMPP-based applications.Wed Oct 03 13:46:10 CEST 2007System Sciences, 1999. HICSS-32. Proceedings of the 32nd Annual Hawaii International Conference on10 pp.+Rethinking media richness: towards a theory of media synchronicityTrack11999media, richness, media-richness, media-synchronicity, synchronicity The paper describes a new theory called a theory of media synchronicity which proposes that a set of five media capabilities are important to group work, and that all tasks are composed of two fundamental communication processes (conveyance and convergence). Communication effectiveness is influenced by matching the media capabilities to the needs of the fundamental communication processes, not aggregate collections of these processes (i.e., tasks) as proposed by media richness theory. The theory also proposes that the relationships between communication processes and media capabilities will vary between established and newly formed groups, and will change over timeWed Oct 03 13:46:10 CEST 2007Software, IEEE617--26Architectural mismatch: why reuse is so hard121995architectural-mismatch, icse_exp_report_06 Why isn't there more progress toward building systems from existing parts? One answer is that the assumptions of the parts about their intended environment are implicit and either don't match the actual environment or conflict with those of other parts. The authors explore these problems in the context of their own experience with a compositional approachWed Oct 03 13:46:10 CEST 2007System Sciences, 1996., Proceedings of the Twenty-Ninth Hawaii International Conference on ,418--427 vol.3Lessons from a decade of group support systems research31996gss A decade of research, development, and implementation of group support systems has occasioned the learning of many lessons. The paper uses a heuristic model to compare group support systems to other groupware, and then summarizes many lessons learned about GSS in the laboratory and in the fieldWed Oct 03 13:46:10 CEST 2007Software, IEEE552--61Enabling Collaboration in Distributed Requirements Management232006plugin, engineering, requirements eclipse, ditributed, Requirements management, one of the most collaboration-intensive activities in software development, presents significant difficulties when stakeholders are distributed, as in today's global projects. After a review of requirements management in current work practices, the authors describe EGRET, a collaborative requirements management tool for distributed software development teams. They present their design motivations for EGRET, a preliminary evaluation of its usability, and directions for further enhancement. This article is part of a special issue on Global Software Development.Wed Oct 03 13:46:10 CEST 2007Software, IEEE346--55Developing groupware for requirements negotiation: lessons learned182001groupware, requirements negotiations, distributed, Defining requirements is a complex and difficult process, and defects in the process often lead to costly project failures. There is no complete and well-defined set of requirements waiting to be discovered in system development. Different stakeholders: users, customers, managers, domain experts, and developers, come to the project with diverse expectations and interests. Requirements emerge in a highly collaborative, interactive, and interdisciplinary negotiation process that involves heterogeneous stakeholders. At the University of Southern California's Center for Software Engineering, we have developed a series of groupware implementations for the WinWin requirements negotiation approach. The WinWin approach involves having a system's success-critical stakeholders participate in a negotiation process so they can converge on a mutually satisfactory or win-win set of requirements. The WinWin groupware system, which has evolved over four generations, enables and facilitates heterogeneous stakeholder participation and collaboration. Each generation reflects an increase in our understanding of what is needed for successful WinWin groupware operations and technology support. The authors present the major lessons they learned during WinWin's developmentWed Oct 03 13:46:10 CEST 2007Internet Computing, IEEE388--95JXTA: a network programming environment52001networking, p2p, jxta, protocols JXTA technology, from Sun Microsystems, is a network programming and computing platform that is designed to solve a number of problems in modern distributed computing, especially in the area broadly referred to as peer-to-peer (P2P) computing or P2P networking. JXTA provides a network programming platform specifically designed to be the foundation for P2P systems. As a set of protocols, the technology stays away from APIs and remains independent of programming languages. This means that heterogeneous devices with completely different software stacks can interoperate through JXTA protocols. JXTA technology is also independent of transport protocols. It can be implemented on top of TCP/IP, HTTP, Bluetooth, HomePNA, and many other protocolsWed Oct 03 13:46:10 CEST 2007Professional Communication, IEEE Transactions onMarch1Paradox of richness: a cognitive model of media choice482005paradox media-richness, Researchers have long studied the effects of social presence and media richness on media choice and the effects of media use. This focus on social presence and social psychological theories has led to valuable research on communication. However, little research (either empirical or theoretical) has been done to understand the ways in which media choices influence the cognitive processes that underlie communication. In this paper, we present a cognitive-based view of media choice and media use, based on dual process theories of cognition, which argue that in order for individuals to systematically process messages, they must be motivated to process the message and have the ability to process it. We argue that the use of rich media high in social presence induces increased motivation but decreases the ability to process information, while the use of lean media low in social presence induces decreased motivation but increases the ability to process information. The paradox of richness lies in its duality of impact: from a cognitive perspective, rich media high in social presence simultaneously acts to both improve and impair performance.Wed Oct 03 13:46:10 CEST 2007Proceedings of the Computer Supported Cooperative Work (CSCW'04)Taking it out of context: collaborating within and across cultures in face-to-face settings and via instant messaging2004common-ground, grounding Wed Oct 03 13:46:10 CEST 2007HICSS (3)34--40Personal Nature and Ambiguity as Sources of Message Equivocality: An Extension of Media Richness Theory.1996media-richness media-naturalness, Wed Oct 03 13:46:10 CEST 2007Internet Computing, IEEE365--74Merging project planning and Web enabled dynamic workflow technologies42000workflow milos, project-change-management, distributed-software-development, gsd, The MILOS system supports dynamic coordination of distributed software development teams by integrating project planning and workflow technologies over the Internet.

As a result, the peer-to-peer (P2P) paradigm is receiving significant attention as an alternative. The authors propose a multilayer P2P framework for developing distributed synchronous collaborative systems using asynchronous P2P platforms. They have used the framework to develop a shared Web browser using the Java programming language and the JXTA platform.Wed Oct 03 13:46:10 CEST 2007System Sciences, 1998., Proceedings of the Thirty-First Hawaii International Conference on48--57 vol.1Beyond media richness: an empirical test of media synchronicity theory11998media-richness, phd media-synchronicity, One widely accepted theory on media use is media richness theory. However, media richness theory was developed without consideration of new electronic media and the many social factors that can influence media selection, communication processes, and outcomes. Recent empirical investigations have raised questions about media richness theory's applicability to these new media. Therefore, the paper presents a new theory called media synchronicity theory (MST) which proposes that all tasks are composed of two fundamental communication processes (conveyance and convergence). Thus, communication effectiveness is influenced by matching the media capabilities to the needs of the fundamental communication processes, not aggregate collections of these processes (i.e., tasks) as rested in examinations of media richness theory. A laboratory experiment was conducted to provide an initial investigation into the theoretical underpinnings of MST. The study examined the influence of different media on conveyance and convergence effectiveness. Results from the study provide preliminary support for the concepts embodied in MST
