    Open Access Scientometrics and the UK Research Assessment Exercise

    No full text
    Scientometric predictors of research performance need to be validated by showing that they have a high correlation with the external criterion they are trying to predict. The UK Research Assessment Exercise (RAE) -- together with the growing movement toward making the full-texts of research articles freely available on the web -- offer a unique opportunity to test and validate a wealth of old and new scientometric predictors, through multiple regression analysis: Publications, journal impact factors, citations, co-citations, citation chronometrics (age, growth, latency to peak, decay rate), hub/authority scores, h-index, prior funding, student counts, co-authorship scores, endogamy/exogamy, textual proximity, download/co-downloads and their chronometrics, etc. can all be tested and validated jointly, discipline by discipline, against their RAE panel rankings in the forthcoming parallel panel-based and metric RAE in 2008. The weights of each predictor can be calibrated to maximize the joint correlation with the rankings. Open Access Scientometrics will provide powerful new means of navigating, evaluating, predicting and analyzing the growing Open Access database, as well as powerful incentives for making it grow faster

    Mapping Big Data into Knowledge Space with Cognitive Cyber-Infrastructure

    Full text link
    Big data research has attracted great attention in science, technology, industry and society. It is developing with the evolving scientific paradigm, the fourth industrial revolution, and the transformational innovation of technologies. However, its nature and fundamental challenge have not been recognized, and its own methodology has not been formed. This paper explores and answers the following questions: What is big data? What are the basic methods for representing, managing and analyzing big data? What is the relationship between big data and knowledge? Can we find a mapping from big data into knowledge space? What kind of infrastructure is required to support not only big data management and analysis but also knowledge discovery, sharing and management? What is the relationship between big data and science paradigm? What is the nature and fundamental challenge of big data computing? A multi-dimensional perspective is presented toward a methodology of big data computing.Comment: 59 page

    New Media & Youth Identity. Issues and Research Pathways

    Get PDF
    Media have held a considerable and growing place in the social environment of industrial society in recent decades, transforming the perception that a people have of their place in the world and of their memberships and belonging, creating new paths for social relations, affecting lifestyles, socialization, and communication processes, and the construction of identity itself. The relationship between young people (especially teenagers and adolescents) and new media shows some peculiarities which are worth further reflection to understand the extent and outcomes of these social changes. This article aims to investigate the discourse on youth identity and new media in the social science literature, determining which are the key trends and exploring the more relevant research questions about this theme and the way these topics relate to one another. Titles and abstracts of articles published during the period 2004 \u2013 2013 were selected from the Scopus social sciences database and they were analysed using different content analysis techniques supported by the T-Lab software. The international literature on these topics presents a certain liveliness and heterogeneity in themes and its perspectives on theoretical and empirical research. Nevertheless, it has been possible to identify some key trends, focusing mainly on the idea of active identity construction by new media
