The ParaScope Editor is a new kind of interactive parallel programming tool for developing scientiic Fortran programs. It assists the knowledgeable user by displaying the results of sophisticated program analyses and by providing editing and a set of powerful interactive transformations. After an edit or parallelism-enhancing transformation, the ParaScope Editor incrementally updates both the a...

The present widespread interest in the use of electronic media for learning presents an unprecedented opportunity for leveraging the computational medium’s strengths for learning. However, existing software tools provide only primitive support for online knowledge-building discourse. Further work is needed in supporting coordinated use of disciplinary representations, discourse representations,...

Science mapping aims to build bibliometric maps that describe how specific disciplines, scientific domains, or research fields are conceptually, intellectually, and socially structured. Different techniques and software tools have been proposed to carry out science mapping analysis. The aim of this article is to review, analyze, and compare some of these software tools, taking into account aspe...

We conducted a series of experiments on collective multiple criteria decision making in a spatial context. The first experiment allowed us to understand the needs of participants and facilitator (mediator) of the decision making process. This gave us the design basis for developing a set of interactive software tools to support decision making by individuals and groups. The tools were tested an...

We have constructed a set of ontologies modelled on conceptual structures elicited from several domain experts. Protocols were collected from various experts who advise on the selection/ specification and purchase of PCs. These protocols were analysed from the perspective of both the processes and the domain knowledge to reflect each expert’s inherent conceptualisation of the domain. We are par...

The difficulty of sustaining ICT4D projects in developing nations is a formidable issue encountered by project managers. Addressing this issue is vital given reasons such as the opportunity cost of IT investment failure in developing-world contexts. This paper presents a study which explores the sustainability of ICT4D projects via a case study of a large-scale, nation-wide, government sector I...

Two main approaches to knowledge management (KM) have been followed by early adopters of the principle: the process-centred approach, that mainly treats KM as a social communication process; and the product-centred approach, that focuses on knowledge artefacts, their creation, storage and reuse in computer-based corporate memories. This distinction is evident not only in KM implementations in c...

This paper argues that one reason for the success of collaborative problem solving where individual attempts failed is the polyphonic character of work in small groups. Polyphony, a concept taken from music, may occur in chats for problem solving, transforming dialog into a “thinking device”: Different voices jointly construct a melody (story, or solution) and other voices adopt differential po...
