Development of Computer Science Disciplines - A Social Network Analysis Approach

In contrast to many other scientific disciplines, computer science considers conference publications. Conferences have the advantage of providing fast publication of papers and of bringing researchers together to present and discuss the paper with peers. Previous work on knowledge mapping focused on the map of all sciences or a particular domain based on ISI published JCR (Journal Citation Report). Although this data covers most of important journals, it lacks computer science conference and workshop proceedings. That results in an imprecise and incomplete analysis of the computer science knowledge. This paper presents an analysis on the computer science knowledge network constructed from all types of publications, aiming at providing a complete view of computer science research. Based on the combination of two important digital libraries (DBLP and CiteSeerX), we study the knowledge network created at journal/conference level using citation linkage, to identify the development of sub-disciplines. We investigate the collaborative and citation behavior of journals/conferences by analyzing the properties of their co-authorship and citation subgraphs. The paper draws several important conclusions. First, conferences constitute social structures that shape the computer science knowledge. Second, computer science is becoming more interdisciplinary. Third, experts are the key success factor for sustainability of journals/conferences

Some "Lessons Learned" on Social Software for Professional Learning

Research report of the ProLearn Network of Excellence (IST 507310), Deliverable 15.5This deliverable's Conclusion lists some lessons learnt regarding the use of social software for professional learning. The conclusion is based upon experiences and insights reported by PROLEARN members, and also the following three recent items: A report about a workshop conducted at the European conference on Computer-Supported Cooperative Work in Limerick, Ireland tackling the gap between CSCW and Social Software; a report about a track at the Professional Training Facts in Stuttgart, Germany; a questionnaire designed and distributed to get data on the impact of social software on European technology enhanced learning industries

Стягивающиеся системы гиперонов и эволюция звезд

Рассматривается влияние предположения об отсутствии насыщения в системе гиперонов на эволюцию звезд. При этом предположении существует новый механизм для выделения энергии в звездах, связанный с превращением нуклонов в стянутые системы гиперонов. Этот механизм может предотвратить гравитационное самозамыкание звезд в результате гравитационного коллапса. Обсуждается возможность реализации указанного механизма генерации энергии в квазарах

Transferring a Question-Based Dialog Framework to a Distributed Architecture

Inquiry skills are an essential tool for assessing and integrating knowledge. In facilitated face-to-face settings, inquiry skills were improved successfully by using a “question-based dialog” and its resulting visual representation. However, groups that work without a facilitator, or in which members collaborate asynchronously or in different geographical regions, such as Communities of Practice (CoP), cannot schedule face-to-face inquiry meetings. This paper summarises the unmet requirements of CoPs for a collaborative inquiry tool found by previous research on the Noracle model and proposes a distributed Web architecture as a solution. It mitigates the need for a common infrastructure, central coordination or facilitation, addresses the evolutionary nature of communities of practice and reduces the cognitive load for the individual by filtering and organising the representational artefacts with respect to the social network of the community. The implementation we envision in this paper aims at applying the concept to a much broader audience, ultimately replacing the need for local meetings

Variety in the Knowledge base of knowledge intensive business sectors

25 páginas, 4 tablas, 1 figuraKnowledge Intensive Business Services (KIBS) are intermediary firms which specialize in knowledge screening, assessment and evaluation, and trade professional consultancy services. The remarkable rise of this broad class of activities is perceived by many as the natural by-product of modern knowledge economies within which increasing specialisation induces the need for professional agents in the markets for external knowledge. This paper addresses critically a conceptual flaw in the specialised literature which portrays KIBS as a homogeneous group of activities. Using official data on occupational information in the United States we observe and analyse high variety across KIBS sectors’ occupational structures and skill requirements.European Community (FP7-PEOPLE-IEF-2008-235278)Davide Consoli acknowledges financial support from the European Community (FP7-PEOPLE-IEF-2008-235278).Peer reviewe
