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
One War, Two Different Perspectives: Identifying the Main News Sources in the Coverage of the 2003 War in Iraq by Al-Jazeera and CNN
No full textThis thesis seeks to identify the main sources of news in the coverage of the 2003 war in Iraq by the Arab channel Al-Jazeera and CNN. It distinguishes the news sources that journalists of CNN and Al-Jazeera have depended on while covering or reporting the events of the war and examines why they gave more airtime to certain news sources than others. Content analysis is used as the main research method and the Glasgow University Media Group’s work is adopted as a model. The data for the research is five prime time news hours chosen from five-day intervals during the war from the coverage by both channels.
This study also examines the two channels’ different perspectives towards the event. This takes into account their histories, their stated position regarding their role and their editorial practices. At the same time there will be an attempt to further contextualize this issue by looking at the flow of the world news across borders, the development of Arab media before and after the emergence of satellite broadcasting and by briefly reviewing the history of Western media war reportage.
The thesis concludes that the main sources on CNN were the ‘coalition’ military and official sources. By contrast, Al-Jazeera’s coverage gave almost equal time to other perspectives such as anti-war voices and ‘independent’ analysts. Consequently it is argued that Al-Jazeera’s coverage was more balanced and multiperspectival

Living with coffee
No full textThe underpinning theme of this exegesis is to provide an overview of the conceptual foundations supporting the documentary 'Living with Coffee' which I produced. The main historical, theoretical and artistic perspectives that have contributed to this production will be explained and defended as the most suitable for my work on this documentary as it relates to fair trade. Fair trade, in particular the fair trade of coffee is the wider framework for 'Living with Coffee'. In summary, my work relied not only on technical and practical efforts of producing a piece of journalistic art but also on sound theory and research findings. The intention of my documentary 'Living with Coffee' is to look into the following question: What effect does the 'café culture' and consumers' choices within it have on the coffee producers and could we sip our way to change? People who consume coffee have the power to change the lives of poor producers for the better. This documentary chose coffee as the commodity in question and analyzed its journey from its production by the coffee producers (or as often referred to in this piece, "cafeteros" a common name given to coffee growers in Colombia), to the places where it is traded and, finally, to those that consume it

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
