A Study of The New York Times Coverage of the Darfur, Sudan Conflict, July 2003 - July 2006
No full textxiv, 109 p. : ill., map. A print copy of this title is available from the UO Libraries, under the call number: KNIGHT PN4899.N42 T55 2008This multi-method study examines how The New York Times reported on the
Darfur conflict in Sudan, which has led to an estimated 300,000 deaths and over 2.3
million people displaced due to fighting between tribes of Arab and Black Sudanese.
Drawing on postcolonial and normative theories and prior studies of Africa's
representation, I analyze how the conflict was framed and what role sources played in
reinforcing or resisting Western neocolonial values. I also explore how news-making
processes impacted journalists' reporting on Darfur.
The content and textual analyses largely support results of prior studies on news
framing of Africa. However, interviews with five New York Times journalists reveal that
the individual biases and motives of the journalists and their sources significantly
influenced the coverage. While the journalists participated in news-making processes distinguishable by journalist goal, source availability, and source credibility, their sources
also provided information that reinforced certain media frames.Adviser: H. Leslie Steeve
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
Artificial Intelligence and Journalism: An Agenda for Journalism Research in Africa
No full textGlobally, newsrooms are adopting various forms of artificial intelligence (AI) as part of the newsgathering, production and distribution process. Western countries and China, in particular, are leading the innovation of AI in newsrooms—testing technologies that include machine learning, automated content creation and moderation and speech-to-text programs. The adoption of AI in newsrooms, and research of its impact, has predominantly focused on Western countries. Although some African countries have begun incorporating AI into sectors such as government agencies, health, education and finance, little information exists about how newsrooms on the continent are using AI technologies. In this paper, we propose a research agenda to advance the scholarship and understanding of the use of AI in African newsrooms and its implications for journalism in Africa. Through a systematic search of databases, we examine the current use of AI in newsrooms in Africa, along with a review of the opportunities and challenges it presents for journalists. We also present a comprehensive examination and discussion about the theoretical frameworks being used to examine newsroom processes—and the opportunities to adapt those theories to analyse the use of AI in African-led scholarship. Also included in the study are recommendations for addressing methodological challenges related to the use of AI in newsrooms
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
