The impact of ICT sophistication on geographically distant networks: the case of space physics as seen from France

This paper examines scientific collaboration between French public research teams and distant partners. We first analyse the role and the development of trust and then, the relation between the degree of sophistication of Information and Communication Technologies (ICT) and the constraint of geographical proximity. In that purpose, we present a typology of the different kinds of knowledge and a classification of technologies. A case study in the field of space physics allows us to confront our theoretical elements to real life. We study the evolution of ICT sophistication parallel to collaboration patterns. Finally, we give some recommendations for public funding of virtual networks.collaboratory, knowledge transfer, trust, ICT classification, space physics

Virtual Institutes: Between Immersion and Communication

In the two expressions "virtual reality" and "virtual community", the term "virtual" has different meanings. A virtual reality is a depiction or, more generally speaking, a sensuous representation of reality that allows - mainly by means of interactivity - to experience various features of reality without actually being in contact with the reality depicted. Therefore, any interactive depiction that is able to imitate reality to such an extent that a high degree of sensory-motor immersion becomes possible is called a virtual reality (Heim 1998, 6f). Since reality is always much more complex than its depiction and full of unpredictable surprises, hardly ever a user has doubts about the difference between the depiction and the thing depicted. Nevertheless, there are good reasons for preferring the imitation to the reality: at least, the imitation is usually not as dangerous as reality sometimes turns out to be. Accordingly, quite different platforms for virtual institutes may be used emphasizing either the immersion aspect or the communication aspect. The decision for a platform depends on the goals pursued with the institute: text-based chat systems allow virtual communities to flourish, single-user VRML scenes convey a highly immersive 3D impression to its users. This is particularly true for virtual institutes realized as a 3D environment, as well as for corresponding virtual communities since 3D environments are adequate for certain tasks only. As an overall framework for the evaluation it is helpful to distinguish three major application areas: research, presentation, and communicative work. The Virtual Institute for Image Science (VIB), which we would like to describe in the following (3) as a case study, is almost exclusively designed for the third task: communicative working. It intends to provide a working space persons can share for joint projects despite being physically separated. Before describing the VIB in more detail we would like to give an overview of virtual institutes between the poles of realistic immersion and of communication in a community (2). The discussion of the case study leads to some more general considerations about the balance virtual institutes must find along that bi-polar dimension (4). In the concluding remarks we focus on the technical tools for virtual communities in 3D presently available

The Discourse of Digital Deceptions and ‘419’ Emails

This study applies a computer-mediated discourse analysis (CMDA) to the study of discourse structures and functions of ‘419’ emails – the Nigerian term for online/financial fraud. The hoax mails are in the form of online lottery winning announcements, and email ‘business proposals’ involving money transfers/claims of dormant bank accounts overseas. Data comprise 68 email samples collected from the researcher’s inboxes and colleagues’ and students’ mail boxes between January 2008 and March 2009 in Ota, Nigeria. The study reveals that the writers of the mails apply discourse/pragmatic strategies such as socio-cultural greeting formulas,self-identification, reassurance/confidence building, narrativity and action prompting strategies to sustain the interest of the receivers. The study also shows that this genre of computer-mediated communication (CMC) has become a regular part of our Internet experience, and is not likely to be extinct in the near future as previous studies of email hoaxes have predicted. It is believed that as the global economy witnesses a recession, chances are that more creative and complex ways of combating the situation will arise. Economic hardship has been blamed for fraud/online scams, inadvertently prompting youths to engage in various anti-social activities.

Relationship Quality in the Context of Computer-Mediated Communication - A social constructionist approach

This paper contributes to possible answers to the question: What are the effects of computermediated communication on relationship qualities in organizations? To answer this question without oversimplifying the phenomena an adequate research methodology has to be found. First, the interrelationship between computer-mediated communication (CMC) and relationship quality is reviewed. CMC-theory will be described from three main perspectives and the risks and chances for relationship quality will be shown. The review indicates that most studies in the field are founded on a positivistic basis. Relationships are treated as static dyads neglecting contextual factors. Thus, the insight into relational processes in computerized environments remains limited. As an alternative a research methodology based on the epistemological stance of social constructionism is proposed. It will be explained, how the researchers’ view can be broadened by applying the method of the ‘narrative interview’ in practice based studies in computer-mediated contexts. In the concluding part, the contribution of this approach to research and practice will be discussed.Computer-mediated communication, relationship quality, social constructionism

RECOLED: A group-aware collaborative text editor for capturing document history

This paper presents a usability analysis of RECOLED, a shared document editor which supports recording of audio communication in remote collaborative writing sessions, and transparent monitoring of interactions, such as editing, gesturing and scrolling. The editor has been designed so that the collaboration results in the production of a multimedia document history which enriches the final product of the writing activity and can serve as a basis for post-meeting information retrieval. A discussion is presented on how post-meeting processing can highlight the usefulness of such histories in terms of tracking information that would be normally lost in usual collaborative editing settings

Computers that smile: Humor in the interface

It is certainly not the case that wen we consider research on the role of human characteristics in the user interface of computers that no attention has been paid to the role of humor. However, when we compare efforts in this area with efforts and experiments that attempt to demonstrate the positive role of general emotion modelling in the user interface, then we must conclude that this attention is still low. As we all know, sometimes the computer is a source of frustration rather than a source of enjoyment. And indeed we see research projects that aim at recognizing a user’s frustration, rather than his enjoyment. However, rather than detecting frustration, and maybe reacting on it in a humorous way, we would like to prevent frustration by making interaction with a computer more natural and more enjoyable. For that reason we are working on multimodal interaction and embodied conversational agents. In the interaction with embodied conversational agents verbal and nonverbal communication are equally important. Multimodal emotion display and detection are among our advanced research issues, and investigations in the role of humor in human-computer interaction is one of them

Can Intelligent Environments be Trustworthy? Designing for trust in Scientific Communication: Concept of Habitable Interfaces (Position Paper)

In this paper we propose the concept of Habitable Interfaces. This concept builds on values-based trust. We hypothesise that representations and interactions built on scientific metaphors and concepts and organised based on the knowledge whithin particular scientific domain will enable values-based trust. Habitable interfaces may provide better information exchange within scientific communities
