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
From the political to the personal: Constructing politicians’ biographies in the Nick Robinson podcast ‘Political Thinking’
Get PDFPolitical podcasts have captured a global audience and emerged as an important innovation space in journalism. One of the most popular formats is the ‘extended interview podcast’. This study employs conversation analysis to examine how this format has been used to facilitate more personal and informal encounters between journalists and politicians who are usually associated with the accountability news interview. BBC Radio 4’s podcast ‘ Political Thinking with Nick Robinson’ is used as a case study. The analysis shows that Political Thinking provides a discursive context for politicians to construct and perform their personal identities, in contrast to their traditionally more formalised political performance as institutional representatives. The looser structure of the podcast, relative to the tightly scheduled news interview, affords Robinson the discursive space for more reflexive handling of politicians’ personal narratives. Talk is mutually co-operative and conversational. Similarly to the celebrity talk show Political Thinking has an experiential focus, oriented towards the narrative exploration of personal experience as a device to contextualise politicians’ careers and value systems. This is complemented with more playful sequences in which Robinson collaborates with politicians to curate their non-political identities and reveal details of their personality that may help the audience to see them in a new light. Through this process, politicians become personal storytellers, whose thoughts, emotions and non-political identities are brought to the fore above issues of policy and current affairs. In turn, Robinson allows politicians to bridge the gap between their institutional identities as politicians and their personal reflections as individuals
Reinventing the news? The discourse of UK news podcasts
No full textThis thesis examines the rise of news podcasts in the UK and their role in
reimagining journalism, focusing on evolving norms of news presentation and how
they are legitimated. Three complementary case studies support this analysis. Case
1 concerns the meta-journalistic discourse of news podcasts and how practitioners
negotiate the boundaries of best practice in industry discourse. 11 episodes of meta-podcasts (podcasts about podcasting) are explored using thematic discourse
analysis, finding news podcasts are discursively constructed as an innovative
journalistic genre that can remedy flaws of broadcast news, such as stale news
presentation, lack of depth and overly rigid impartiality regulations. Cases 2 and 3
focus on the micro discourse analysis of news podcasts as interactionally co-constructed media texts within the tradition of broadcast talk. Case 2 studies six
episodes of BBC’s Newscast and Global’s The News Agents to examine the norms
and practices of the news chatcast subgenre. The case finds many characteristics of
established modes of news broadcasting persist, packaged in a more informal and
conversational format that accentuates aesthetic liveness. Additionally, hosts utilise
personal talk sequences to enhance their self-branding as ‘celebrified’ journalists in a
personality-driven podcast market. Case 3 investigates the remediation of political
radio phone-ins into asynchronous podcast question-and-answer segments where
listeners send in emails that the host reads-and-responds to. Independent
monologue podcast Roll Politics with Steve Richards is used as a case study.
Richards produces his monologue as synthesised dialogical, inserting liveliness and
interactivity into a participation framework devoid of liveness. At the same time, the
segment is used to produce strong affective ties with the audience who are
discursively produced as an intimate listening community. Overall, the thesis argues
that news podcasts represent a repackaging of news for a medium that values
authenticity and sociability rather than a wholesale reinvention of news
