- Abstract
- Investigates evolving notions and expressions of community and networks, in the context of educational culture which is engaged in the process of discovering the opportunities and challenges presented by communications and information technologies. Parallel to this is the task of identifying key elements or threads that might be common to a wide diversity of educational electronic communities

- Abstract
- Purpose - The purpose of this paper is to attempt to provide a review of the growing literature on co-authorship networks and the research gaps that may be investigated for future studies in this field. Design/methodology/approach - The existing literature on co-authorship networks was identified, evaluated and interpreted. Narrative review style was followed. Findings - Co-authorship, a proxy of research collaboration, is a key mechanism that links different sets of talent to produce a research output. Co-authorship could also be seen from the perspective of social networks. An in-depth analysis of such knowledge networks provides an opportunity to investigate its structure. Patterns of these relationships could reveal, for example, the mechanism that shapes our scientific community. The study provides a review of the expanding literature on co-authorship networks. Originality/value - This is one of the first comprehensive reviews of network-based studies on co-authorship. The field is fast evolving, opening new gaps for potential research. The study identifies some of these gaps.

- Abstract
- This article aims to identify whether different weighted PageRank algorithms can be applied to author citation networks to measure the popularity and prestige of a scholar from a citation perspective. Information retrieval (IR) was selected as a test field and data from 1956-2008 were collected from Web of Science. Weighted PageRank with citation and publication as weighted vectors were calculated on author citation networks. The results indicate that both popularity rank and prestige rank were highly correlated with the weighted PageRank. Principal component analysis was conducted to detect relationships among these different measures. For capturing prize winners within the IR field, prestige rank outperformed all the other measures

- Abstract
- This paper presents an evolving framework for human information behaviour, including information exploration, seeking, filtering, use and dissemination. It is based on empirical studies of human information behaviour in a variety of settings (Iivonen & Sonnenwald, 1998; Sonnenwald, 1993, 1995, 1996) and theories from a variety of research traditions, including information science, communication, sociology and psychology that inform our understanding of human information behaviour. I begin formulating the framework by discussing fundamental concepts, such as context, situation and social networks. Building on these concepts, I propose a series of propositions that strive to elucidate the framework. Key ideas in the framework include the introduction of the role of social networks in information exploration, and the concept of an `information horizon' in which we can act to explore information.

- Abstract
- To what extent is the destiny of a scientific paper shaped by the cocitation network in which it is involved? What are the social contexts that can explain these structuring? Using bibliometric data, interviews with researchers, and social network analysis, this article proposes a typology based on egocentric cocitation networks that displays a quadruple structuring (before and after publication): polarization, clusterization, atomization, and attrition. It shows that the academic capital of the authors and the intellectual resources of their research are key factors of these destinies, as are the social relations between the authors concerned. The circumstances of the publishing are also correlated with the structuring of the egocentric cocitation networks, showing how socially embedded they are. Finally, the article discusses the contribution of these original networks to the analyze of scientific production and its dynamics.

- Abstract
- This study explores the similarity among six types of scholarly networks aggregated at the institution level, including bibliographic coupling networks, citation networks, cocitation networks, topical networks, coauthorship networks, and coword networks. Cosine distance is chosen to measure the similarities among the six networks. The authors found that topical networks and coauthorship networks have the lowest similarity; cocitation networks and citation networks have high similarity; bibliographic coupling networks and cocitation networks have high similarity; and coword networks and topical networks have high similarity. In addition, through multidimensional scaling, two dimensions can be identified among the six networks: Dimension 1 can be interpreted as citation-based versus noncitation-based, and Dimension 2 can be interpreted as social versus cognitive. The authors recommend the use of hybrid or heterogeneous networks to study research interaction and scholarly communications.

- Abstract
- Image content opens up exciting possibilities for stand-alone media, distributed networks, online networks, and on-site publishing from information systems for use by the general public, for research, collection management, education and distance learning. These developments coincide and overlap with widespread new questioning and thinking as to the role of museums in relation to their diverse publics and also may have many parallels in the library world. They raise difficult questions about intellectual propriety rights - copyright protection, fair renumeration and complex questions concerning moral rights. Clearly international cooperation, working partnerships and consortia are going to gain further importance and significance

- Abstract
- A summary of a thesis based on the supposition that in an era of increasing leisure more time is to be available for cultural activities and that analysis can lead to a better grasp of the concept of cultural information. Discusses: the relationship of government, cultural networks and the cultural engineering sector to information; existing kinds of cultural information, their use and the impact on them of new technologies; and the characteristics and role of information professionals in this sector

- Abstract
- Reviews the origin of the information superhighway paradigm and the many resulting national initiatives, including the US National Information Infrastructure and the world wide global information infrastructure. Quotes the guiding principles, and presents a list of possible future services, together with an overview of the major technological avenues. Discusses the current prototype of the future universal information infrastructure. i.e. the Internet and the WWW. Discusses which requirements are currently satisfied by the Internet plus WWW combination, and which capabilities are not yet provided. Presents a possible scenario of evolution

- Abstract
- Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.
