Collaborative work typically involves both individual and group activities. Individual efforts may be combined through group negotiation processes. Personal perspectives on shared information are thereby intertwined and merged into group understanding. Computer support for personal and group perspectives allows people to view and work on a shared information repository in different contexts. Th...

We discuss an approach in which engineers formally and iteratively construct information representations, called Perspectives, from information in other Perspectives using personal computational assistants, called Perspectors. Engineers can select from predefined, reusable, Perspectors, or program new Perspectors, and compose them into directed acyclic graph structures, called Narratives, to qu...

On their own, the cognitive psychology and sociocultural constructivist perspectives fails to furnish a complete account of adult learning and development. In the past, these perspectives have been viewed as being incompatible because their origins reside in rival and distinct areas of theorising. This paper seeks to propose a more comprehensive basis for adult learning and development by advan...

Mediation analysis has become a very popular approach in psychology, and it is one that is associated with multiple perspectives that are often at odds, often implicitly. Explicitly discussing these perspectives and their motivations, advantages, and disadvantages can help to provide clarity to conversations and research regarding the use and refinement of mediation models. We discuss five such...

Models provide an alternative perspective for the understanding of a software system. However, models reflect the state of the system at the time of their creation (or last updating) but they do not reflect intermediate changes during the system’s evolution. Depicting perspectives without showing changes is like watching a movie through a small set of still pictures (i.e., no motion). This pape...

Abstract Economic considerations are an important component in the planning and execution of a telemedicine program. The goal of this review is to familiarize readers with economic concepts relevant to the analysis of telemedicine programs. Economic perspectives, cost attribution, types of economic analysis, and commonly encountered problems will be discussed as they pertain to telemedicine. So...

We introduce a new type of workflow design system called e-BioFlow and illustrate it by means of a simple sequence alignment workflow. E-BioFlow, intended to model advanced scientific workflows, enables the user to model a workflow from three different but strongly coupled perspectives: the control flow perspective, the data flow perspective, and the resource perspective. All three perspectives...

Project managers and developers need to acknowledge the influence of IS stakeholders’ perspectives and perceptions on the outcome of requirements negotiation the essential component of requirements elicitation. This paper describes a conceptual study, which demonstrates such an influence and asserts that stakeholder perspectives, goals and issues are the key to negotiators’ perceptions of the s...
