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
Is Twitter a counter public?: comparing individual and community forces that shaped local Twitter and newspaper coverage of the BP oil spill
Get PDFIf society is to avoid another disaster like the 2010 BP oil spill, the U.S. must reexamine its future energy policies and government regulations of industry. In the wake of such disasters, the news media should fulfill a surveillance function and raise these critical issues. But an analysis of 164 Gulf Coast newspaper reporters' coverage of the BP oil spill showed that these journalists largely failed to do so. This dissertation examines individual and community-level variables that prevented the journalists from raising more critical questions in the aftermath of the oil spill, and compares their coverage and the forces that shaped it to the Tweets of 240 most-followed Gulf Coast Twitter users. This dissertation seeks to answer whether, in the context of the BP oil spill, Twitter might have served as a counter-public, which challenged the social, political, and economic forces that constrained journalists' coverage. This study found a striking degree of similarity in journalists' and Twitter users' coverage of the oil spill, raising questions about whether Twitter is an alternative medium, and whether media-centric or more general sociological theories are most fruitful for understanding the similarities between these media
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
Unveiling the agenda-building process for corporate social responsibility and the impacts of corporate communications on the process
Get PDFThe four main purposes of the present study were to examine the following: 1) how the news media have discussed CSR-related issues, 2) what the main sources are for the media agenda as it relates to CSR issues, 3) how the media and sources interact to set the media agenda, and 4) what influence corporate communication efforts have on the agenda-building process. To explore these inquiries, press releases and news articles were content analyzed to represent the corporate agenda and the media agenda. As a result, a total of 7,672 press releases and 1,067 news articles were analyzed involving the 223 corporations in the study sample. For the monitoring group agenda, data from KLD, a secondary source, were used. All data were measured three times over a three-year period, from January 1, 2008, to December 31, 2010. Three research questions were developed focusing on the degree of the media's attention to CSR news, the tone of the media's CSR coverage, and the sources for the media's CSR coverage. The results showed that 21.62% (n = 230) of news articles coded covered CSR issues, that the most common tone of CSR news coverage was neutral and mixed, and that corporate sources were the most used sources for CSR news coverage. Seven groups of hypotheses were designed to test the first level and the second level of agenda building. In order to examine the relationships among the corporate agenda, the media agenda, and the monitoring group agenda, a three-wave, three-variable model was developed. The simple summary of the results is as follows: the media determined who set the CSR agenda (first-level agenda building). At the attribute level of the agenda, the monitoring group had impacts on setting the negative attribute CSR agenda (second-level agenda building), but not on tone, whereas corporations had impacts on setting the positive tone of the CSR agenda (second-level agenda building), but not on substantive attributes. The contributions to agenda-building theory and the implications for corporate communications are discussed
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
Meet the New Players: A Study of Digital Native Journalists and Journalistic Professionalism
Get PDFDigital native journalists have brought new blood as well as challenges to contemporary journalistic professionalism. This dissertation employs a national survey of both digital native journalists and legacy journalists and focuses on the cognitive, normative, and evaluative dimensions of their journalistic professionalism. Findings suggest that both the “professionalism” concept and the operational measures are suitable for evaluating the traits and characteristics of digital native journalists, and digital native journalists are currently serving as both preservers and transformers of journalistic professionalism. Findings of this study serve as the groundwork for observing and understanding digital native journalists and their organizations as new entrants to journalism. Journalistic professionalism is undergoing a transformation, and identifying how digital native journalists differentiate from legacy journalists on aspects of professionalism has afforded some clues to how journalistic professional values and practices will develop in the future.Doctor of Philosoph
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
A Multi-method Examination of Race, Class, Gender, Sexual Orientation, and Motivations for Participation in the YouTube-based "It Gets Better Project"
Get PDFOn September 15, 2010, Dan Savage and Terry Miller created a YouTube channel that turned into a global phenomenon: the It Gets Better Project (IGBP). This multi-method study employs: 1) Multimodal Critical Discourse Analysis (MCDA) to examine race, class, gender, and sexual orientation within IGBP videos; and 2) video chat-based in-depth interviews for determining participants' motivations for IGBP participation and production of crowdsourced, social media-based strategic communication. Using sociologist Patricia Hill Collins' matrix of domination as a theoretical framework for understanding structural, disciplinary, hegemonic, and interpersonal oppressions that led to the IGBP's creation, video production, and video content, this empirical study draws from a sample of 21 videos and 20 interviews. MCDA findings reveal that participants presented a pared-back version of their own racial, class, gender, and sexual identities; projected their identities onto viewers; and created and perpetuated myths through their video narratives. In doing so, certain identities are presented to the exclusion of others, potentially leaving viewers outside of these boundaries more isolated, at risk for being even more suicidal because again they do not fit in, and confused about what identities are even possible. Thus, the IGBP videos both challenge the matrix of domination and reify its very existence. Interview data reveal four categorizations, including participants': 1) felt sense of camaraderie with at-risk LGBTQ and questioning youth; 2) urgency to rectify what was missing from their own sexual identity development; 3) need to alter the media representation of lesbian and gay men in - and through - the IGBP; and 4) impact of their current positionality. Participants were forthcoming about the intersectionality of their racial, ethnic, gender, sexual, age, religious, and geographic identities and how those led to their IGBP participation, though that intersectionality rarely surfaced explicitly in their video content. In addition to contributing to numerous literatures on LGBTQ suicide, bullying, and harassment; LGBTQ media representation; strategic communication; and online participatory culture, this study has several methodological, theoretical, and practical implications for both scholars and practitioners, including participant recruitment, video chat-based interviewing, application of the matrix of domination to strategic communication efforts, and more.Doctor of Philosoph
