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
Längsschnittliche Perspektiven auf ethnische Diversität und soziale Kohäsion : Massenmedien, Nachbarschaften und rämliche Mobilität
No full textA growing strand of research in the social sciences demonstrates that social trust and other indicators of social cohesion are lower in ethnically diverse localities. This negative association has reached the status of a stylized fact, an empirical regularity that stimulates a host of empirical and theoretical work that tries to explain, contest and replicate the association. The interest in this association in sociology might be due to the fact that the implications of this broader strand of literature go beyond the local effects of ethnic diversity. They touch upon the question whether immigration affects aggregate societal integration, and thus link to a topic that is of interest to sociologists since the early beginning of the discipline. Against the backdrop of this larger scholarly debate, this thesis is part of a broader research agenda that not only empirically investigates the association between neighborhood diversity and social cohesion itself (see study III), but also focuses on the processes that surround this association. One pillar of this agenda is a focus on processes of ethnic segregation and individual residential choice that create what is later measured as neighborhood ethnic composition (see study II). A second pillar moves the debate on social cohesion to higher levels of analysis by focusing on macro-level sources of group threat such as the national media (see study I). In Study I, "Mass Media and Concerns about Immigration in Germany in the 21st Century: Individual-Level Evidence over 15 Years", Christian S. Czymara and I use panel data to analyze how the attention that the topic of migration receives in the mainstream media predicts within individual changes in concerns about immigration in Germany from 2001 to 2015. A particular focus is on the question whether local ethnic composition moderates the media salience effect. In study II, I analyze White Flight for the German case. White Flight is widely known in the U.S. American literature, describing mobility flows of ethnic majority individuals out of neighborhoods with high shares of other ethnic groups. Here, I focus on one plausible mechanism for White Flight: having children. The fact that parents might change their neighborhood preferences strongly after having children is often noted in the literature, but there is still a lack of longitudinal evidence. I address this gap by relying on panel fixed-effects models to account for time-stable neighborhood and household specific traits. Study III deals with a core element of social cohesion: individual social connections to neighbors. Previous studies on the association between ethnic diversity and local social cohesion are mostly cross-sectional. Extending prior research, I add a dynamic element to the analysis: the length of residence in a neighborhood. I empirically show whether the formation of contacts with neighbors over time depends on the ethnic diversity of the neighborhood. However, asking a longitudinal research question also poses empirical challenges. As a potential means to address those issues, I propose a method to deal with possible bias due to selective mobility out of neighborhoods during the period of observation
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
