‘If It Looks Like a Letter, Reads Like a Letter, and Talks Like a Letter’: The Case of Nikephoros Gregoras’ Letter Collection
No full textThe Student Becomes the Teacher: Nikephoros Gregoras’ <i>Hortatory Letter Concerning Astronomy</i>
No full textThe present inquiry examines the change in the intellectual climate of early Palaiologan Byzantium characterised by the prominence of mathematical astronomy and the importance of the successful demonstration of related disciplines. It traces their impact on the late Byzantine discourse concerning knowledge of the natural world as reflected by contemporary historiography, as well as on the related book production and circulation.
In particular, the chapter focuses on Nikephoros Gregoras’ (c. summer 1293/June 1294–1358/1361) Roman History, which lists numerous astronomical events, such as solar and lunar eclipses, the observation of comets and the configuration of the stars at a given moment in time. Book VIII, in particular, offers important examples of the incorporation of astronomy-related material into the historiographical narrative as it comprises Gregoras’ Hortatory Letter Concerning Astronomy and his discourse on the date of Easter. The present contribution features a case study of the Hortatory Letter and analyses its insertion in both Gregoras’ Roman History and the astronomical miscellany Vat. gr. 1087 where it serves as introduction to the entire volume.
Finally, the present chapter proposes that Gregoras’ Hortatory Letter, in both its contexts of preservation (in Vat. gr. 1087 and in the Roman History), illustrates the interplay between, firstly, the increased occurrence of significant astronomical phenomena such as the lunar and especially the solar eclipses observable in Constantinople; secondly, the exceptional and rare mathematical expertise Gregoras acquired and demonstrated; thirdly, the change in his social and intellectual status from student of astronomy to one of the very few masters of the quadrivium in the capital; and finally, his newly acquired role as Theodore Metochites’ intellectual heir and the one responsible for the preservation of the latter’s scholarly legacy, especially in the context of the revival of Ptolemaic astronomy.This chapter was written as part of the project UMO-2015/19/P/HS2/02739, generously supported by the National Science Centre, Poland.

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
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
