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
The Media Maze: are experts telling us what to do or giving us information? (A critical discourse analysis of the Norwegian media's presentation of climate experts)
Get PDFThe aim of this thesis is to get insight into the media discourse on climate change experts In the Norwegian media. The goal is to investigate how these experts are being presented in the media: rather than what experts are being presented. There is seemingly not much research on the media's presentation of climate change experts in a Norwegian context. Hence, I would like to argue that this thesis can provide a small contribution and insight, into how some Norwegian newspapers portray climate experts in their articles. On the other hand, I don't claim that this thesis can give two lines under the answer, but rather, as said, give a little insight into how the Norwegian media present climate change experts, by indicating trends that are showing up in the data material. The research question for this thesis is:
How do the Norwegian media present experts on climate change issues?
I have researched this question by conducting a critical discourse analysis while accounting for relevant theories on both discourse and expertise. The data material consists of four of the biggest national newspapers in Norway, collected strategically from the four latest time periods when an IPCC report was released while using the search words climate and expert.
My analysis indicates that there has been an increasing trend to reference experts on climate change issues in the chosen newspapers, as well as an overall increasing trend in the number of articles published where these experts are presented. It also indicates that multiple different types of experts are references in articles discussing climate change. Seemingly, there has been a shift from referencing more natural science experts at the beginning of the century to referencing more political experts and social science experts in recent years. Further that the experts are presented as people who give information that either advocates actions or reasons or not. And the majority of the experts presented in this data material were presented as advocating either a specific action or reason for why something was occurring. Further, there seemingly were no local experts presented and the IPCC was often not included in these articles
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
