Participatory design amalgamates the expertise of interdisciplinary specialists with the taskspecific expertise of end-users. Groupware design is widely recognised as benefiting from participative approaches. Recognition of this ideal, however, does not preclude the failure of groupware design due to poor communication and inadequate understanding between participants. We provide a grounding in the problems affecting groupware success, and introduce four design principles that guide all those involved in design around the pitfalls that have been encountered, some repeatedly, by (...) groupware.

New forms of information technology, such as email, webpages and groupware, are being rapidly adopted. Intended to improve efficiency and effectiveness, these technologies also have the potential to radically alter the way people communicate in organizations. The effects can be positive or negative. This paper explores how technology can encourage or discourage moral dialogue -- communication that is open, honest, and respectful of participants. It develops a framework that integrates formal properties of ideal moral discourse, based on Habermas' theory (...) of communicative action, with properties of informal communication that help sustain good moral conversations. Ten criteria distilled from these works form the basis of a template that can be used for assessing the positive and negative impacts of emerging information technologies on moral dialogue. (shrink)

This article reports on an empirical investigation of long-term use of a groupware system in a spatially and massively distributed network of educators. It is a case study based investigation aimed at understanding the impacts of collaboration technology in supporting social interaction. The paradigm of social constructivism and the perspective of structuration are proposed as frameworks for understanding the impacts of technology on mediating social interaction. Utilizing these perspectives in an empirical investigation, the case study findings demonstrate how collaboration (...) technology can serve as a change agent in transforming the culture and structure of social interaction. This is enacted in two ways: through the various meanings which people construct when interacting with technology and in benefiting from the structural properties of a system through its technical affordances.

Dans un environnement organisationnel instable et concurrentiel, l'usage des outils de groupware serait tributaire de la convergence entre, d'une part, les formes de communication permises par ces outils et, d'autre part, les stratégies relationnelles mises en oeuvre pour développer la confiance entre les acteurs. Les pratiques de collaboration qui font appel aux technologies informatiques de travail en groupe dépendraient alors de cette logique d'usage. Une recherche empirique, réalisée dans des entreprises et des centres de recherche de la Silicon Valley, (...) conforte ces hypothèses.In a changing and competitive organizational environment, the use of groupware tools seems to rely on the convergence of the communication allowed by these tools and the relational strategies necessary to develop trust. Consequently, computer supported collaborative practices would depend on this logic of use. Empirical research realised in firms and in research centres in Silicon Valley tends to confirm these hypotheses. (shrink)

This paper presents a platform for developing, testing and executing synchronous collaborative applications in a distributed, heterogeneous environment. Even though several environments exist nowadays, specific problems are not treated satisfactorily. Especially in ‘real’ network environments, problems like unstable network connections and low bandwidths have to be considered.The DreamTeam platform addresses the special needs of environments with non-optimal characteristics which can, be found in distance learning scenarios. DreamTeam comprises a development environment, a simulation environment and a runtime environment; it is based (...) upon the concept of a fully decentralised architecture and encourages rapid prototyping.DreamTeam supports developers of shared applications through a component concept. Using components helps to divide a software project into well-defined parts. Well-documented interfaces help to reduce integration efforts and improve software quality. A selection of sample applications with DreamTeam validates our design concept. (shrink)

Two areas of importance for agents and multiagent systems are investigated: design of agent programming languages, and design of agent communication languages. The paper contributes in the above mentioned areas by demonstrating improved or novel applications for deontic logic and normative reasoning. Examples are taken from computer-supported cooperative work, and electronic commerce.

waC provides a variety of different graphical notification mechanisms which can be coupled to specific working situations using the AREA model. We also report on the evaluation of the system under real-life conditions in a German federal ministry.

The impressive development of electronic communication techniques has given rise to virtual communities. The nature of these computer-mediated communities has been the subject of much recent debate. Are they ordinary social groups in electronic form, or are they fundamentally different from traditional communities? Understanding virtual communities seems a prerequisite for the design of better communication systems. To clarify this debate, we will resort to the classical sociological distinction between small traditional communities (based on personal relations) and modern social groups (bound (...) by looser, more impersonal links). We will argue that the discussion about virtual communities is often vitiated by a simplistic assimilation to traditional communities, whereas they may be in fact quite different and much more impersonal. Virtual communities are often bound by reference to common objects or goals, and not by personal relations. In this respect, virtual communities are just another example of a long-term evolution of modern society toward more abstract social relationships. (shrink)

This paper describes the escape/intervention concept as it is used in the agent growing environment framework. The Escape and Intervention is used in many multi-disciplinary areas, including agent research, artificial intelligence, groupware and workflow, process support, software engineering, and social sciences. Based on an ontological perspective, this paper explains how an interaction-oriented agent architecture and language (used for modelling, simulation, and development) makes use of an interaction pattern that is inspired from social contexts seen as multi-agent systems.

Resumen. Este artículo ofrece una propuesta enfocada a optimizar el proceso de evaluación sobre el aprovechamiento del alumno, en un ambiente virtual, mediante el concepto GROUPWARE:, técnicas de comunicación grupal, utilizando las Nuevas tecnologías de Información y las Comunicaciones [NTIC’s], como herramientas básicas, llevando el registro y seguimiento estadístico del aprovechamiento actitudinal del estudiante, posibilitando así, el uso y la construcción de índices significativos, seguros y fiables, que permitan al instructor/facilitador/tutor, gestionar de un diagnóstico, sobre el comportamiento, esfuerzo, dedicación (...) y actitud del aprendiz, obteniendo como resultado la participación integra del alumno en los cursos tomados en la plataforma colaborativa permitiendo en consecuencia las medidas preventivas/correctivas sobre la conducta continuamente observada del alumno en el entorno en línea.Palabras claves.

On line environment, new technologies on information and telecommunication, assessment process, teaching-learning process, student performance, groupware. (shrink)

Being present in the same room not only enables people to exchange non-verbal communication but also the physical properties of the room offer opportunities for action and thus contribute to the ongoing social process. This paper discusses concepts from social and behavioural sciences to better understand the role of physical environments and artefacts with respect to cooperation among a group of people. Barker's behaviour setting theory is studied and applied to electronic settings. Requirements for ‘electronic behaviour settings’ to enable situated (...) cooperation in CSCW across spatial and temporal distances will be derived. Electronic behaviour settings should embody their own physical behaviour, and thus provide electronic places for cooperation. Adaptation to a particular group process can be achieved through a particular constitution of the setting and its adaptation in the course of practical use. This paper studies how this concept maps to existing groupware systems and outlines from practical experience whether this concept may help users adopt groupware in their work practice. This approach will contribute to the support of situated action in computer-supported cooperative work. (shrink)

In groupware tools, the activation of a function may affect other users who might have conflicting interests. We developed technical mechanisms to support users in resolving them. Contrary to current implementations of groupware tools, these mechanisms strengthen the position of the users who are affected by the activation of said functions. Supporting the visibility of a function's activation, and providing a channel for communication or means to intervene against the function's activation are approaches which constitute a framework to (...) implement these mechanisms. We conclude with showing implementation examples of the framework and their evaluation in the POLITeam project. (shrink)
