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
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
Who thinks the media is hostile?! : an examination of individual differences predicting the hostile media effect concerning news media coverage of individuals with a migratory background in Germany
No full textThe present study explores individual differences related to the perception of the media coverage of immigrants as biased. Building on previous research, relations with the extremity in preexisting attitudes toward immigrants and in affective ratings of non-immigrants versus immigrants are examined. Additionally, the present study extends previous work by investigating dogmatism and intellectual humility, including their potential moderating roles on the relations of extremity in attitudes and affective ratings with perceived media bias. A sample of N = 212 (59% men) individuals from the general German population completed self-reports on their preexisting attitudes and affective ratings, as well as dogmatism and intellectual humility online. Moreover, participants rated their perception of news media coverage of immigrants as biased against their views. Results indicate that particularly more extreme negative attitudes toward immigrants and affective ratings favoring non-immigrants relative to immigrants are positively associated with perceiving the media coverage of immigrants as biased. No robust relations of dogmatism, intellectual humility, or their interactions with the extremity scores with perceived media bias were found. These findings underline the importance of negative extremity in (out) group-related attitudes and affect in perceiving the media coverage as biased. New approaches investigating media perceptions from a group-related perspective are discussed.Projekt DEALMinisterium für Wissenschaft, Forschung und Kunst Baden-Württember
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
Uncovering latent profiles of political news consumers and their associations with political views and their extremity
No full textIn today's high-choice media environment, the relations between news consumption and (extreme) political views receive extensive attention. While social media and news aggregators are often blamed for political polarization, theories from media psychology highlight the importance of additional aspects of news consumption, aside from the media types used, in impacting the formation of political views and thereby, for instance, polarization. However, these aspects are typically studied in isolation, neglecting the heterogeneity in where and how news can be consumed. Based on this observation, the present work investigated the conjoint relations of various aspects of news consumption across media types with political views and their extremity. Study 1 included two samples of N = 714 (sample 1) and N = 721 (sample 2) participants completing an online survey assessing political news consumption habits and general political views, namely, ideology and affective polarization. Study 2 included two samples of N = 725 (sample 3) and N = 713 (sample 4) participants completing scales on issue-specific political views, namely, attitudes on war and the war against Ukraine. Latent Profile Analyses revealed four mostly media type-specific news consumer profiles replicated across samples, indicating that individuals choose one media type, like social media, aggregators, or print media, and devote considerable time to consuming political news from various sources, including attitude-incongruent news and diverse perspectives, from the same selected media type. While these profiles differed on sociodemographic and personality variables, few significant relations were found between these profiles and political views. These findings highlight the complexity of these relations and challenge the assumption that only certain media types, and news consumption via them, drive political extremity.Graduate & Professional Training Center Ul
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
