This paper describes an impact analysis technique that identifies which parts should be retested after a system written in C++ is modified. We are interested in identifying the impacts of changes at the class member-level by using dependency relations between class members. We try to find out which member functions need unit-level retesting and which interactions between them need integration-l...

The use of virtual project teams (VPTs) is increasingly prevalent in organizations today. This increasing reliance on VPTs introduces obvious challenges relating to virtual team members’ ability to communicate and effectively share knowledge particularly when the project is highly complex. These tasks are further exacerbated by the nature of virtuality itself and the attributes of the collabora...

Sonification is generally considered in a statistical data analysis context. This research discusses the development of an interface for live control of sonification – for controlling and altering sonifications over the course of their playback. This is designed primarily with real-time sources in mind, rather than with static datasets, and is intended as a performative, live data-art creative ...

Online facilitation in a cross-cultural collaborative context is increasingly prevalent, but limited research has been conducted on the related issues, two of which are examined in this paper with reference to the empirical data of an exploratory user trial involving multinational facilitators, students and researchers. Results of our meticulous content analysis of online forum messages and vid...

This paper describes an artifact-centric approach to a traditional ideation method, brainstorming. Picturestorming uses human-centric images to stimulate ideas in a collaborative setting. In an exploratory study, I found that picturestorming may address limitations of standard brainstorming by reducing evaluation apprehension and production blocking. Pictures also support reflection and group c...

The concept of polycentricity has gained significance in discussions on spatial development in Europe in recent years. This paper presents new evidence on polycentric city networks in Central-Eastern Europe based on selected results of the ESPON project POLYCE (Metropolisation and Polycentric Development in Central Europe). The authors discuss existing applications of the concept in the context...

Integrating users on web-based platforms is achieved in many settings such as communities for innovation as well as in different areas like healthcare. In web-based communities, interaction is the basic mechanism from which users as well as organizers derive benefit and, thus, is very important for indicating whether a community is successful or not. Facilitation of users can help to address ch...

Virtual teams are becoming common place in many organizations. These teams are geographically distributed and communicate via computer-mediated communication systems. Two factors have been shown to affect virtual team communications, the development of relational links and the amount of trust between team members. However, most virtual team members do not receive training on how to effectively ...

Empirical evidence is mounting that good urban design fosters the formation of social fabric. Existing evidence is however limited in at least two respects. First, empirical studies have focused largely on social interactions taking place within the residential neighborhood, while leaving social encounters near the workplace unconsidered. Second, while various studies have examined the impact o...

In the era of open and distributed innovation, Information Technology (IT) must be leveraged by organizations to reach, record and review ideas from internal (eg. employees) and external sources (eg. business partners). IT can support and enable this process, but only when its roles are understood and when properly deployed. Existing research has inadequately established these roles. Using the ...
