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
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
La question raciale sur le littoral de Los Angeles (années 1920-années 1970)
No full textWhile Los Angeles's beaches were officially desegregated in 1927, informal segregation persisted throughout the 20th century, either through violence or subtle territorial strategies. African Americans and Latinos nonetheless asserted their "right to the beach" by using diverse tactics, from founding a private beach club to fighting back against their aggressors. In the postwar era, racial minorities were more numerous at the beach and were consequently subject to intense police surveillance - while simultaneously, municipalities attempted to get rid of the last, now shameful traces of racial segregation along the shore. By looking at racial relations on urban beaches, a kind of leisure space that is rarely studied by historians, this article sheds light on the multiple spatial strategies used to contain and exclude people or, on the contrary, to subvert racial boundaries.Si les plages de Los Angeles sont officiellement déségrégées en 1927, une ségrégation informelle persiste tout au long du siècle, par la violence ou par le biais de stratégies territoriales subtiles. En retour, les Noirs mais aussi les Latinos revendiquent leur "droit à la plage" en usant de tactiques diverses, de la fondation d'un club privé à la confrontation violente avec leurs agresseurs. Dans l'après-guerre, les minorités raciales, désormais plus nombreuses sur le sable, font l'objet d'une surveillance intense de la part des autorités, alors même que les municipalités tentent d'effacer les dernières traces, désormais jugées honteuses, de la ségrégation sur le littoral. Observer les relations raciales depuis les plages d'une grande ville, un espace public méconnu des historiens, fait ressortir la multiplicité des stratégies spatiales déployées pour circonscrire et exclure ou, au contraire, pour subvertir les barrières raciales
Les frontières invisibles de la plage : l'interdiction du port du maillot de bain dans le Los Angeles du début du siècle
No full textLa plage, un révélateur des tensions qui traversent la société à un moment donné ? Elsa Devienne montre ici comment les plages californiennes cristallisèrent, au début du XXe siècle, les tensions nées de la remise en cause des valeurs victoriennes et rendirent manifestes, à travers la mise en scène des corps, les changements à lʼœuvre dans lʼordre moral et la société états-unienne
