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
Harald Sigurdsson and the Russo-Byzantine War of 1043
Get PDFThe present article analyzes Kekaumenos’ commentary on the service of Harald Sigurdsson in the Byzantine army. Special attention is given to the composition of Consilia et Narrationes and the historiographic perception of this text. It then discusses Kekaumenos’ commentary in light of Harald’s adventures in the Haralds saga Siguðarsonar and the story about the attacks of Rus’ in the Byzantine literature. The author attempts to show that Constantine IX Monomachos tried to leave the large groups of mercenaries in Constantinople. Furthermore, the emperor’s attitude to Harald and his warriors was related to the events of Russo-Byzantine war in 1043. Constantine IX Monomachos dispersed these mercenaries into the themes. John Scylitzes wrote that the emperor put a guard over them to prevent them from inciting a rebellion. These arrests could explain Harald’s mysterious detention in the reign of Constantine IX Monomachos. It is possible to conclude that Harald’s detention was caused by the Russo-Byzantine war in 1043

No full textThe purpose of the dataset C. elegans muscle aging is to deduce the age of the nemathode based on images of muscles. Images of C. elegans were taken at different chronological ages. This image is part of the day 1 data set. Note that the morphological and chronological ages are not fully correlated due to the variability among individuals even though the individuals are genetically identical. The source for the dataset is Laboratory of Genetics/NIA/NIH
