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
Who Compiled and Edited the Mashhad Miscellany?
Get PDFThe identity of the editors of the Mashhad miscellany generated considerable scholarly debate for a couple of decades after Togan’s discovery of the Mashhad manuscript in 1923, but interest in the topic declined after the middle of the century. In the last seventy years, it is the miscellany’s four texts, in particular the Kitāb of Ibn Faḍlān, that have monopolized scholarly attention. This paper reopens the file on the mysterious editors in the belief that their role remains the key to understanding the majmūʿa as well as its component texts. It reexamines the paratextual apparatus with which the editors framed the miscellany and concludes that the editors did not belong to the Mashriqī literary elite as earlier scholars maintained. The “editors” were in all probability not men of flesh and blood, but the fictional creations of the traveler, poet, and nadīm Abū Dulaf al-Khazrajī, author of the miscellany’s two Risālas. His role as the mastermind of the Mashhad miscellany compels us to reevaluate the miscellany’s literary context and to think again about the provenance, structure, and contents of its four texts
A Numismatic History of the Early Islamic Precious Metal Coinage of North Africa and the Iberian Peninsula
No full textThis dissertation uses all of the available evidence provided by coins to construct a numismatic history of the early Islamic precious metal coinage of North Africa and the Iberian Peninsula. The dissertation begins with a review of the analysis undertaken by earlier scholars, followed by an explanation of the adopted methodology, including the approach to the primary and secondary sources and the description of the methods used in the metrological, metallurgical, and die estimation analyses. The balance of the dissertation is divided into three sections. The first section is the typology, which divides the coinage into four series: Series 1, the Two Imperial Bust type; Series 2, the Latin Epigraphic type; Series 3, the Bilingual type; and Series 4, the Post-Reform type. The typology analyses each series in detail. This section also discusses the iconographical elements of the coinage, with a further chapter providing an analysis of certain anomalous examples that do not readily fit into the typology. The second section encompasses the analysis of the metrological and metallurgical aspects of the coinage and the estimation of the number of dies for each series. The final section combines the numismatic evidence and the historical record provided by a variety of secondary sources into a numismatic history of the two regions. This section includes a discussion of the historical context prior to, during, and after the Muslim conquest of North Africa and the Iberian Peninsula, as well as a discussion of find spots and circulation. The dissertation concludes with a comparison of the evolution of the precious metal coinage in North Africa and the Iberian Peninsula to the evolution of Islamic coinage in other regions of the Umayyad Caliphate and an exploration of the underlying nature of the coinage (i.e. regional, Imperial, etc.)
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
