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
Parallele Wissensproduktionen - Statement zu einem möglichen Kulturschaffen
No full textIn dem Text Parallele Wissensproduktionen.Statement zu einem möglichen Kulturschaffen spricht die Autorin Yvette Mutumba über ihre Praxis als Kunsthistorikerin, Kuratorin und Chefredakteurin, mit welcher sie versucht Methoden anzuwenden, die marginalisierte und zugleich komplexe (Kunst-)Geschichten in einer zugänglichen Weise bearbeiten und vermitteln. Ziel ist hierbei, parallele Narrationen innerhalb eines kulturellen Diskurses und Kunstkanons zu schaffen. Mutumba erläutert dies im Text anhand von ausgewählten Beispielen: die drei Ausstellungen „Ware und Wissen – or the stories you woulnd’t tell a stranger“, „El Hadji Sy: Painting, Performance, Politics“ und „A Labour of Love“, die as Kustodin am Weltkulturen Museum, Frankfurt am Main ko-kuratierte
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 Pioneering Collection
Get PDFIn addition to its collection of 67.000 ethnographic objects, the Weltkulturen Museum in Frankfurt began engaging with contemporary art practices in Africa forty years ago. Since 1974, the museum has collected almost 3.000 works by artists from the Democratic Republic of Congo, Kenya, Namibia, Nigeria, Senegal, South Africa, Tanzania, Uganda and Zimbabwe, mainly produced during the 1960s, 1970s and 1980s. Included here are early works by internationally renowned artists El Anatsui, Twins Seven Seven, Peter Clarke, Chéri Samba, El Hadji Sy and Vincente Malangatana. The museum's research into contemporary art from the African continent is pioneering as it started long before the so called “global turn” in 1989. In this regard, the Weltkulturen collection is unique as it includes works from that specific time. A further defining feature is the collection's four main strands—works from Nigeria, Senegal, Uganda and South Africa—acquired by German collectors on behalf of the museum, who had different affiliations with the respective regions. The text traces the motivations, ideas and strategies behind the build-up of the Weltkulturen collection while also looking at the question of collecting and presenting contemporary art in the context of an ethnographic museum.Il y a quarante ans que le Musée Weltkulturen à Francfort a commencé de se pencher sur la pratique de l'art contemporain en Afrique en plus de sa collection de 67 000 objets ethnographiques. Depuis 1974, le musée a recueilli près de 3 000 œuvres d'artistes de la République Démocratique du Congo, du Kenya, de Namibie, du Nigeria, du Sénégal, de l'Afrique du Sud, de la Tanzanie, de l'Ouganda et du Zimbabwe, surtout produites pendant les années 1960, 1970 et 1980. Sont incluses ici les premières œuvres d'artistes de renommée internationale, El Anatsui, Twins Seven Seven, Peter Clarke, Chéri Samba, El Hadji Sy et Vincente Malangatana. Ce musée est pionnier dans ses recherches sur l'art contemporain du continent africain car il a commencé avant ce qu'on appelle le « global turn » en 1989. À cet égard, la collection Weltkulturen est unique car elle rassemble des œuvres de cette période précise. Une caractéristique le définissant en outre sont les quatre principaux volets de la collection — des œuvres en provenance du Nigeria, du Sénégal, de l'Ouganda et de l'Afrique du Sud — acquises par des collectionneurs allemands au nom du musée, qui avaient différentes affiliations vers ces régions. Le texte retrace les motivations, les idées et les stratégies derrière l'accumulation de la collection Weltkulturen tout en analysant la question de la collecte et celle de la présentation de l'art contemporain dans le contexte d'un musée ethnographique
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
