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...

background : due to specific conditions in hospitals such as accumulation, existence of disable persons and patients, different and complex equipment, chemical and infectious substances, flammable materials and ionized radiations, safety precautions is essential to prevent the occurrence of incidents such as fire, electric shock hazard and exposure to excessive levels in hospitals. this was the...

Cloud technology in a multi-enterprise, collaborative context is one of the most promising topics at IT-Supply Chain (SC) intersection. Cloud comes with well-proven advantages and cost savings; enabling collaboration and business intelligence. Cloud transition is still on-going with individual enterprise-level transitions. However, collaborative paradigm dictates that entire network well-being ...

International collaboration in science continues to grow at a remarkable rate, but little agreement exists about dynamics of growth and organization at the discipline level. Some suggest that disciplines differ in their collaborative tendencies, reflecting their epistemic culture. This study examines collaborative patterns in six previously studied specialties to add new data and conduct analys...

This paper presents a critique of the normative, buyer-supplier literature and in addition suggests that the more empirically-based literature needs to expand its scope of attention beyond its traditional confines of attention. Four main deficiencies are identified within much of the existing buyer-supplier literature. Firstly, collaborative buyer-supplier theories fail to discriminate sufficie...

In social collaborative crowdsourcing platforms, the votes which people give on the content generated by others is a very important component of the system which seeks to find the best content through collaborative action. In a crowdsourced innovation platform, people vote on innovations/ideas generated by others which enables the system to synthesize the view of the crowd about an idea. Howeve...
