End User Development offers technological flexibility to encourage the appropriation of software applications within specific contexts of use. Appropriation needs to be understood as a phenomenon of many collaborative and creative activities. To support appropriation, we propose integrating communication infrastructure into software application that follows an“easy-to-collaborate”-principle. Su...

The world wide web provides an integrating platform for intra and inter-organizational systems. Understanding how the many actors interested in web infrastructure influence design, development and practice can provide insight as to how organisations can manage and make effective use of web infrastructure. The socio-technical perspective views information systems as being socially constructed by...

Societies rely on the social infrastructure for proper societal function. When crises emerge, the importance of the social infrastructure magnifies as people often rely on others, both known and unknown, for support. For citizens experiencing a war environment, however, societal trust can be affected and we show how technologies are used to maintain and create social infrastructures for resilie...

Building an up-do-date information technology (IT) infrastructure is one of the key issues in supporting both the technological and the economical advancement of developing countries. Several concepts promise to meet the special requirements arising, when applying them to the telecommunication infrastructure of these countries. With its ability to be applied to an existing copper-based public s...

If we were to have a Grid infrastructure for visualization, what technologies would be needed to build such an infrastructure, what kind of applications would benefit from it, and what challenges are we facing in order to accomplish this goal? In this survey paper, we make use of the term ‘visual supercomputing’ to encapsulate a subject domain concerning the infrastructural technology for visua...

Distance education (DE), which has evolved under the wings of information technologies in last decade, become a fundamental part our modern system. DE not only replaced traditional method as social sciences and lifelong learning opportunities but also significantly strengthened mathematics, science, engineering fields that require practical intensive study. However, it is deprived supporting so...

This document describes some of the technological aspects of a project devoted to the creation of a factory for language resources. The project’s objectives are explained, as well as the idea to create a distributed infrastructure of web services. This document focuses on two main topics of the factory: (1) the technological approaches chosen to develop the factory, i.e. software, protocols, se...

Using Semantic Web technologies in the domain of online recruitment could substantially increase market transparency, lower the transaction costs for employers, and change the business models of the intermediaries involved. In this paper, we describe how online recruitment processes can be streamlined using Semantic Web technologies. We analyze the realization chances of such a scenario from th...

This paper addresses possible Distributed Denial-of-Service (DDoS) attacks toward the wireless Internet including the Wireless Extended Internet, the Wireless Portal Network, and the Wireless Ad Hoc network. We propose a conceptual model for defending against DDoS attacks on the wireless Internet, which incorporates both cooperative technological solutions and economic incentive mechanisms buil...
