This paper aims at explaining how intermediaries influence collaborative innovation projects, suggesting a conceptual-theoretical framework about intermediaries’ roles and practices. The qualitative research was developed through the case study of the Orange Service Call and Reward project performed by the National Endowment for Science, Technology and the Arts (NESTA) for Orange Labs, the R&D ...

Electronic Assessment systems usually provide an authoring tool for creating activities (mainly closed-type questions) and administering the flow of their presentation and are also complemented with a delivery environment for learners. In this paper, we discuss learner’s control over authored assessment. The prototype application, ReACTS (Re-Adaptable Computerized Testing System), enables learn...

This article aims to identify how knowledge workers develop their own collaboration strategies and techniques for getting their work done in complex, dynamic knowledge intensive work environments. Three case studies have been conducted to explore the nature of routines in different collaborative working settings as they provide sufficient detail to better understand the actual state and problem...

Nowadays, enterprises cooperate more extensively with other enterprises during the entire product life cycle. Temporary alliances between various enterprises emerge such as those in Virtual Enterprises. Collaborative applications are demanded that enable enterprises to engage in such endeavors. This paper aims to present a framework with which collaborative applications can be characterized and...

The Virtual Company educational scenario engages students in a professional setting for working and learning. Students are enabled to develop competencies that are derived from professional practice. This allows us to use assessment strategies that are different from the practice in traditional educational settings. In the Virtual Company educational scenario the competence assessment procedure...

The delayed delivery of the AIRBUS A380© demonstrates the challenges to be faced in the field of cross-company collaboration today. On the one hand, available CWE platforms are used insufficiently. On the other hand, they do not yet support collaboration in a completely adequate way. This paper illustrates the current state of CWE practice by way of a sample company, its internal and external c...

This paper introduces the topic of " Collaborative Distance " within Distributed Collaboration as being an introduction to this Special Issue on Collaborative Working Environments 1 (CWE). It starts in discussing various related concepts, identified during an extensive literature review, on both proximity and distance in distributed collaboration. Then, a Collaborative Distance Framework (CDF) ...

We propose a new approach to commutative watermarkingencryption (CWE). A permutation cipher is used to encrypt the multimedia data, which leaves the global statistics of the multimedia data intact. Therefore, any non-localized watermarking scheme that depends only on global statistics of the multimedia data can be combined with the permutation cipher to form a CWE scheme. We demonstrate this ap...

This paper presents the Unified Collaborative Innovation Framework (UCIF) developed in the European Integrated Project Laboranova (Collaboration Environment for Strategic Innovation). The Framework aims at the support of the early stage innovation process by means of collaborative working environments. As implied by its name, UCIF is a framework, which by definition is a conceptual construct ac...
