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
The Chronology of Greek Bronze Tripods of the Geometric Type and the Possibilities of a Political-Historical Interpretation of the Find Distribution
No full textBronzedreifüsse waren wegen ihres hohen Wertes und ihres Gerätegeld-Charakters besonders geeignet, gesellschaftlichen Rang zu formulieren. Sie wurden nur in einigen ausgewählten (proto)geometrischen Heiligtümern und dort dafür oft in großer Zahl geweiht. Viele dieser Heiligtümer sind später entweder innerstädtische Hauptheiligtümer wichtiger Siedlungskerne bzw. Poleis oder extraurbane Zentralheiligtümer von Ethne (Stämmen), Regionen, Inseln oder Großpoleis oder aber extraurbane panhellenische Heiligtümer. Dies bestätigt, dass Dreifußweihungen den Treffpunkt einer Elite anzeigen. Der Entwicklungsprozess elitärer Öffentlichkeiten wird nun deutlich besser datierbar, da es zum einen im Übergang von später Bronzezeit zu früher Eisenzeit keine Pause in der Produktion von Dreifüssen gab, zum anderen die sog. massiven Dreifüsse mit facettierten recht- oder mehreckigen Beinen, die leichte Fronten zum Betrachter hin ausbilden, bereits seit dem Ende des 11.Jh. produziert wurden, und weiterhin die bekannten tönernen Gussmantelframente aus Lefkandi, die stratigraphisch an das Ende von euböisch Spätprotogeometrisch (um 900) datieren, von der Herstellung eines Π-förmigen Beines eines sog. reliefierten Dreifusses stammen. Olympia und Delphi beispielsweise müssen daher seit dem späten 11. oder dem frühen 10. Jh. regionale Zentren gewesen sein.Bronze tripods were particularly suitable as a means of formulating social status since they were one of the most prestigious types of movable items and because of their character as a exchange-item with a value easy to assess. Offerings of bronze tripods occur by no means in all (Proto-)Geometric sanctuaries but only in a few selected ones, and there often in abundance. Many of theses sanctuaries in later are either principal urban-area sanctuaries of major population nuclei or poleis, or extra-urban central sanctuaries of ethnic groups (tribes), regions, islands or major poleis, or extra-urban Panhellenic sanctuaries. These results reveal furthermore that tripod dedications indicate the meeting point of an elite. The process of development of elite publics becomes now easier to date. In the transition from the late Bronze Age to the early Iron Age there was no break in tripod production; the so-called massive tripods with faceted rectangular or polygonal legs forming slight fronts facing the viewer, were produced already from the end of the 11th century. The known clay-mould fragments from Lefkandi, which are stratigraphically datable to the end of the Euboean late Protogeometric period (c. 900), come from the production of a Π-shaped leg of a so-called relief tripod. Olympia and Delphi, for example, must therefore have been regional centers from the late 11th or early 10th century
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
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
