Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Lessons from Germany for the BBC
Full text linkSince the rushed ‘deal’ between the BBC and the Government last week on the license fee, discussions -including the House of Lords Select Committee inquiry– have focused on the BBC’s governance arrangements and the process of reviewing license fee levels. With the independence of broadcasters again under the spotlight, LSE Postgraduate Anja Noster examines the lessons that the UK can learn from the German system
Variations on the Author
Full text link“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
Full text linkWe 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
Strengthening Journalism in The Digital Age: The Role of External Innovation Support for Journalism
Full text linkExisting literature has extensively examined journalistic innovation actors at the micro and meso levels, including journalistic entrepreneurs, newsrooms, and media organizations. However, few scholarly works have considered the role of external stakeholders that support journalism innovation at the macro level, including public, private, and philanthropic organizations that increasingly provide financial, structural or soft support. Therefore, this dissertation conceptually and empirically explores the relevance of this external innovation support for journalism. It is thereby guided by the following research question: What are the opportunities and limitations of external innovation support for journalism? The work is anchored in existing literature from media innovation and media business studies, media structures and policy literature as well as general innovation (policy) research. Drawing on this body of research, it identifies several research gaps. Notably, there is a scarcity of studies on public innovation support, particularly when compared to the number of studies on private initiatives such as the Google News Initiative or foundation-led efforts. Also, existing studies largely take a normative approach, focusing on ethical concerns and risks of media capture, while its potential benefits remain underexplored. Consequently, this dissertation comprises a total of three studies that aim to fill these gaps and approach the topic from two angles. On one hand, Studies I and II focus on the supporters’ perspective on the context, form and nature of public innovation support for journalism. On the other hand, Study III considers the beneficiaries’ perspective on external innovation support’s effectiveness in helping them overcome challenges in their innovation processes. Methodologically, Study I is conceptual, whereas Studies II and III are empirical, with one adopting a retrospective and the other a longitudinal multiple case study approach. This combination allows for both theoretical exploration of the topic and an in-depth analysis through interviews, document analysis, and observations. The findings introduce a new analytical framework and research agenda for examining (public) support structures for innovation in journalism, as well as offer empirical insights into their functioning. They thereby contribute to both theory and practice and build a strong basis for future studies
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
