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
Epigrafi e cattedrali. Alcune note sulla Hagia Eirene di Costantinopoli
No full textThe Christian commemorative inscriptions by bishops or realized for bishops’ buildings were a particularly privileged topic by Giuseppe Cuscito.
There are not too many specific studies about the episcopal basilica of Byzantium dedicated to (Hagia) Eirene: probably because of its own history and use, very different from the other Byzantine churches in Istanbul: it was never transformed in a mosque and it was open with high difficulty to visitors until few years ago, because its position inside the strictly forbidden area of the Sultan Palace in the Othmans Istanbul.
The most part of the scholars considered the basilica of Hagia Eirene,in addition, essentially only about its wonderful aniconic decoration in the abside: one of the very few examples of Byzantine art during the Iconoclasm.
The commemorative inscriptions, integral part of the building, were considered in the very first studies, but in the following decades have been completely neglected.
The paper has the aim to reconsider the epigraphic equipment of the Hagia Eirene, also in order to interpret the historical reasons that brought the patrons to choose to display in the building some Sacred Writings passages: these very particular Biblical quotations are revealed as essential components of the Constantinople ecclesia episcopalis.L'epigrafia cristiana di apparato, in particolare quella di committenza vescovile o comunque negli edifici di pertinenza episcopale, appare come uno dei temi ricorrenti nella riflessione scientifica di Giuseppe Cuscito. Sulla basilica episcopale della capitale bizantina, dedicata alla (Santa) Pace, non si registrano molti studi specifici - anche per le particolari vicende che l'hanno interessata. La maggiore attenzione degli studiosi è sicuramente stata incentrata sulla decorazione aniconica dell'abside, in quanto uno dei pochi esempi conservati dell'arte bizantina durante la sua fase iconoclastica. L'apparato epigrafico - parte integrante del monumento - pur considerato attentamente nei primissimi studi sull'edificio, in seguito è stato completamente trascurato.
Il contributo intende rivisitare le letture proposte e tentare di interpretare in chiave storica la particolare scelta dei testi - citazioni scritturistiche - che si rivelano come componenti essenziali della ecclesia episcopalis constantinopolitana
