Online Social Networks (OSNs) have an infamous history of privacy and security issues. One approach to avoid the massive collection of sensitive data of all users at a central point is a decentralized architecture. An event invitation feature – allowing a user to create an event and invite other users who then can confirm their attendance – is part of the standard functionality of OSNs. We form...

This paper describes the deployment of Plone, an Open-Source content management system, to support the activities of CALIBRE, an EU-funded coordination action integrating research into Libre software. The criteria by which Plone was selected are described, and the goodness of fit to these criteria is analysed. As a coordination action, CALIBRE involves 12 partners with different requirements an...

The knowledge-intensive information economy is upon us while at the same time existing working organisation and tools are not anymore appropriate to support remote knowledge workers collaborating together, their concurrent tasks and related information “tsunami” over flooding them. As a consequence, working organisation is shifting towards networked individuals driven simultaneously by the nece...

Based on dynamic capability and boundary spanning theory, this study develops a theoretical framework for collaborative BPM in inter-organizational networks. The framework presents collaborative BPM as an organizational capability that serves for connecting business processes through the purposeful employment of boundary objects (e.g., information systems) and boundary spanners (people) at the ...

This document summarizes the study on current and future technologies for collaborative working environments (CWEs) with the focus on whether the current CWEs and their future trends are suitable for large scale multi-national organizations. In this study, we have analyzed structure of ESA with respect to organization, geographical distribution, IT environments and presented a list of state-of-...

In this paper the notion of a Chemical Work ow Engine (CWE) is introduced to support the enactment of scienti c work ows, i.e. computationally intensive tasks involving large datasets. The execution of scienti c work ows require the coordinated use of a large quantity of resources and scheduling of the activities. Furthermore, these workows may pose various dynamic features that need a special ...

Parallel inference machines reduce the evaluation time in object recognition tasks. However, the exploding search space restricts the use of parallel search methods for complex demands. Intelligent software agents as concurrently working units are able to coordinate their capacity for work. Thus, agent-based object recognition is able to concentrate the available resources on regions of the env...

Teachers’ work is influenced by their perception of environment, projecting this into the quality education and product delivered to society. Therefore, study analyzes how environment manifests itself in a Higher Education Institution, considering affiliation, commitment, communication, motivation, recognition, other factors that affect performance university teacher. The results show teachers’...
