SAGE Handbook of Social Media: Introduction
No full textThe world is in the midst of a social media paradigm--a distinctive moment in the history of media communications shaped by the dominance of social media technologies. By social media technologies, we mean those digital platforms, services and apps built around the convergence of content sharing, public communication, and interpersonal connection. Social media have been widely but unequally taken up by the world’s diverse populations, but have an influence on all our lives through pervasive ‘social media logics’ like connectivity (van Dijck & Poell, 2013).\ud

Through its logic of convergence (Burgess, 2017), social media brings with it entanglements between commercial, public and personal contexts. Well-known platforms like Twitter, Facebook, and WeChat, once seen as mere sources of teenage distraction, have become embedded into the ICT infrastructures of corporations, societal organisations, and public institutions. Especially with the rapid uptake of mobile media, these platforms, their uses, and their politics are also increasingly embedded in our everyday life, work and relationships at a very personal and embodied level. \ud

The social media paradigm is also shaping the interests and knowledge practices of media and communication studies. From the mid to the late 1990s, proto-social media like social networking sites and content sharing platforms (from Friendster to MySpace) were objects of burgeoning interest in internet studies, media studies and communication studies. Since then, social media has become a recognisable field of study within these disciplines. As of 2015, this sub-field even has its own journal: Social Media + Society (also published by Sage), as well as a number of edited collections, and now this Handbook
Social media and the cultural and creative industries
No full textAt one level, it makes a lot of sense to discuss social media and the cultural and creative industries (CCIs) together. The creative industries policy discourse emerged in the late 1990s, just as the new breed of Internet companies were emerging whose platform innovations were no longer tied to information and communication technology (ICT) hardware production. At the same time, there has often been a surprising lack of overlap between creative industries debates and those surrounding digital and social media. While many of the most intense debates around the intersection between creative industries and digital culture have been around the changing status of intellectual property, and associated legal, ethical and policy issues, they are increasingly likely to be turning to questions around the political economy of the networked digital and social media platforms themselves
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
