Access to information in digital libraries : users and digital divide

Recognising the importance of information and knowledge in all spheres of human life, the recently held World Summit on Information Society came up with a plan of action for building a global information society. The goal of the world information society initiatives is the same as that of digital library research and development - to make information and knowledge accessibleto everyone in the world. Digital libraries have progressed very rapidly over the past ten or soyears. This paper addresses the two most important aspects of the information society - information users and digital divide. Findings of some large-scale studies on human information behaviour on the web and digital libraries have been discussed. The major findings of a study on access to electronic resources by university students are the presented. Proposed that a one-stop window approach with a task-based information organisation and access system may be the way forward

Library Search UX report summer 2016

During Summer 2016, Imperial College London's Library Information Systems team ran a round of user experience research into the information-seeking behaviour of undergraduate and postgraduate students with a specific focus on the use of the library catalogue and discovery interface. The purpose of the work was to understand user behaviours and preferences to target development of practical improvements to the Library Search interface

Collective Influence of Multiple Spreaders Evaluated by Tracing Real Information Flow in Large-Scale Social Networks

Identifying the most influential spreaders that maximize information flow is a central question in network theory. Recently, a scalable method called "Collective Influence (CI)" has been put forward through collective influence maximization. In contrast to heuristic methods evaluating nodes' significance separately, CI method inspects the collective influence of multiple spreaders. Despite that CI applies to the influence maximization problem in percolation model, it is still important to examine its efficacy in realistic information spreading. Here, we examine real-world information flow in various social and scientific platforms including American Physical Society, Facebook, Twitter and LiveJournal. Since empirical data cannot be directly mapped to ideal multi-source spreading, we leverage the behavioral patterns of users extracted from data to construct "virtual" information spreading processes. Our results demonstrate that the set of spreaders selected by CI can induce larger scale of information propagation. Moreover, local measures as the number of connections or citations are not necessarily the deterministic factors of nodes' importance in realistic information spreading. This result has significance for rankings scientists in scientific networks like the APS, where the commonly used number of citations can be a poor indicator of the collective influence of authors in the community.Comment: 11 pages, 4 figure

Values and behaviours: using the Ten Essential Shared Capabilities to support policy reform in mental health practice

This paper will review aspects of current policy in mental health with specific reference to policy that has a values focus. In this context, values refers to the standards and expectations we hold and which we use to guide aspects of practice performance. Service users state that core values that support, respect choice, collaboration, and customer service are critical foundation stones of a trusting therapeutic relationship. Attending to these foundations for practice has merit in ensuring the quality of care delivery in mental health. This paper will analyse what this means for the mental health workforce in their engagement with service users and delivery of policy priorities. Finally, the paper will explore resources, such as the Ten Essential Shared Capabilities (see Appendix 1), which support engagement and ongoing promotion of person-centred mental health care

The impact of consortia purchasing of periodical publications on the document supply service

Purpose – This paper aims to show the impact of consortia purchased periodical publications on document supply services. These services have undergone considerable changes over the last five years, first decreasing but now recovering. Design/methodology/approach – First, this paper reviews the most recent specialised literature, focusing mainly on the impact of electronic journals in libraries, their effects, and proposed actions. Second, as an example of this new behaviour, presents the document supply service data, as collected in one hospital’s health-science library in the last four years. Findings – As evidenced by the literature, the users’ acceptance of electronic journals has undoubtedly been excellent. Consortia purchasing projects have become a basic tool that expand collections, support cooperative technological development, and require negotiating skills from librarians. But these mass purchases do not seem to be the ideal solution for libraries, they entail losing freedom when choosing the collection and often make library collections homogeneous by publisher. Originality/value – Reflects on what possible causes have led to the current situation and the current way to manage the collection.Publicad

Searching for superspreaders of information in real-world social media

A number of predictors have been suggested to detect the most influential spreaders of information in online social media across various domains such as Twitter or Facebook. In particular, degree, PageRank, k-core and other centralities have been adopted to rank the spreading capability of users in information dissemination media. So far, validation of the proposed predictors has been done by simulating the spreading dynamics rather than following real information flow in social networks. Consequently, only model-dependent contradictory results have been achieved so far for the best predictor. Here, we address this issue directly. We search for influential spreaders by following the real spreading dynamics in a wide range of networks. We find that the widely-used degree and PageRank fail in ranking users' influence. We find that the best spreaders are consistently located in the k-core across dissimilar social platforms such as Twitter, Facebook, Livejournal and scientific publishing in the American Physical Society. Furthermore, when the complete global network structure is unavailable, we find that the sum of the nearest neighbors' degree is a reliable local proxy for user's influence. Our analysis provides practical instructions for optimal design of strategies for "viral" information dissemination in relevant applications.Comment: 12 pages, 7 figure

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users
