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
Identity, Community, and State Formation at Roman Palmyra
Get PDFThis is a study of identity, community, and the process of state formation in the Roman period at Palmyra, an oasis city in the Syrian desert, from the first to third centuries C.E. I address the key issue of cultural transmission and the development of an indigenous Palmyrene identity and community in the Roman Near East, as influenced by their pastoralist backgrounds and their contacts with Parthian and Roman powers. I examine these issues primarily through a re-evaluation of the local epigraphy in its urban context, complemented by examinations of the archaeology of the city and narrative sources. I demonstrate how the Palmyrenes managed to build a civic community that was distinctively Mediterranean in its makeup, and where a small elite dominated public affairs. I demonstrate how, despite increasing Roman influence over the city during the period of this study, the Palmyrenes retained their native identities in a communal setting, characterized by a cultural blend of Roman, Parthian, and indigenous habits
Pella, Jarash, and Amman:Old and New in the Crossing to Arabia, ca. 550-750 C.E.
No full textThe concern of this paper is with the towns of Pella/Fihl, Gerasa/Jarash and Philadelphia/Amman, all located in modern Jordan, during early Islamic times. A long-established road linked these three towns, striking eastwards from Fihl up the Jordan Rift scarp into the highlands of Jordan, eventually reaching the regional capital of Amman. Unlike the route between Qaysariyah and Baysan, the Fihl – Amman road is not described by any of the third/ninth and fourth/tenth century Arabic geographical sources, but archaeologically there is little doubt that this route was active, to varying degrees, in the early Islamic period. The paper investigates the urban nature of these towns at that time, and in what ways these centers differed from their late antique predecessors of, say, the mid-sixth century CE, beginning with Pella/Fihl and then continuing eastwards to Jarash and Amman, and finishing with a reflective look at Skythopolis/Baysa
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
