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
Community-based
No full textThis issue of Logoi has at least three roots and three reasons. The first one is to start a reflection on the so-called Community-based participatory research (CBPR). This dossier is opened by a paper of Meredith Minkler (University of Berkeley) who is one of the founders of the method CBPR and of reflection on it.
This scenario is also linked to the two articles that we present in the section called Research Communities and ABCs, papers which on the one hand refer to the CBPR, but on the other side cross in particular another of our interests: the Abc method. In fact, Logoi is a partner of the research project called An ABC of Democratic Citizenship. “Community-Based Participatory Research” through Sciences & Humanities (University of Bari). The project is presented in this section. While another focus is on Latin America. You can read the contribution of Adriana Fresquet (Río
de Janeiro), Abecedarios audiovisuais comunitarios: de Perú para el mundo.
Let’s come to the third root/reason of this issue: the need to reflect, in many ways and with many languages, on the theme of community.
We therefore have some essays that either starting from some knowledge, disciplines, languages even extra-philosophical, or focusing on authors and specific themes, address the issue-community: Interdisciplinary issues (Simona Cohen - Tel-Aviv; et alii) and Particular issue
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
An ABC of Citizenship, vol. 2
No full textE' il primo di due fascicoli monografici che raccoglie i lavori e le intuizioni nate anche in sinergia con alcune associazioni del territorio pugliese: creare degli Abbecedari della cittadinanza, legati a grappoli di eventi, capaci di coinvolgere territori, scuole e in generale agenzie educative. L'esperienza ha a sua volta sollecitato docenti e ricercatori universitari italiani e stranieri, che hanno inviato i loro contributi. La molteplicità di materiale e l'interesse del percorso teorico-pratico ci ha appunto convinto a dividere quanto giunto in redazione in due fascicoli, che raccolgono saggi legati a 21 sezioni, una per ogni lettera dell'alfabeto di questo ideale abbecedario comunitario: dalla A di amicizia alla Z di Zero povertà. Con contributi anche di tipo internazionale: B. Weber, W. Kohan, E. Cejva
