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
Mapping the citizen news landscape: blurring boundaries, promises, perils and beyond
Get PDFWithin a short space of time, citizen journalism went from something of a novelty to a naturalized part of the news ecosystem and entered the daily language of journalists, journalism educators and a large segment of the global public. As the prolific body of empirical and theoretical research into this phenomenon continues to expand, however, “discourses of citizen journalism reveal an array of virtues in the opinion of advocates striving to transform journalism by improving its civic contribution to public life – and conceal a multitude of sins in the eyes of critics intent on preserving what they perceive to be the integrity of professional practice – in complex, occasionally contradictory ways” (Allan 2013: 8). This chapter offers a necessary critical overview of citizen journalism in its many forms and shapes, with a focus on its promises and perils and what it means for the future of news. We will start with a review of the concept of “citizen journalism” and its many alternative terms, then move to brief note on the long history of citizen journalism, which dates back to the early days of the printing press. This will be followed by our typology of three major forms of citizen journalism (CJ) – citizen witnessing, oppositional CJ and expertise-based CJ – along an assessment of each form’s primary actions, motives, functions and influences. The penultimate part of the chapter will focus on CJ’s flaws and pitfalls – especially the mis/disinformation environment it fosters and the “dialogue of the deaf” it engenders – and place them in the context of the post-truth era to highlight the still critical need for professional journalists. The chapter concludes with a brief review of the understandably but unnecessarily uneasy relationship between citizen and professional journalism and calls for the latter to adopt a new attitude to work well with the former

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
Audiences for Journalism
Get PDFThis entry provides an overview of the relationship between audiences and journalism. Although traditionally, practitioners and journalism scholars have largely neglected audiences, digitalization has enabled and necessitated taking the audiences of journalism seriously. As advertisement revenues continue to decrease, news organizations are increasingly dependent on their audiences for survival. Scholarly interest in audiences has been stimulated by the proliferation of available options for news use
