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
Ciências Sociais e Saúde: Desafios e temas críticos dos Sistemas de Saúde
No full textO presente volume reúne alguns textos, de vários/as autores/as que, entre 2011 e 2014, participaram como conferencistas nos diferentes ciclos anuais de seminários "Ciências Sociais e Saúde", organizados pelo Centro de Estudos Sociais da Universidade de Coimbra. Este volume, à semelhança dos vários seminários que o tornaram possível, apresenta e discute temas e questões de relevância para a compreensão da relação entre saúde e sociedade, conferindo, no entanto, especial enfoque a alguns dos temas mais críticos no âmbito da atualidade dos sistemas de saúde
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
Democracia e Direitos Humanos na Era Digital
No full textPensar os movimentos sociais é encará-los como um sintoma claro e óbvio de violação de direitos, um desafio ao retrocesso da democracia, uma exigência por igualdade e justiça social. Estes movimentos, e seus reportórios de ação, apontam para violações e deficiências do sistema. Neste contexto, o mundo digital veio transformar o impacto e o papel destas lutas. No reverso da promessa emancipatória da tecnologia residem, hoje, ameaças que nos obrigam a reavaliar, mas sobretudo a (re)definir novas ferramentas críticas a partir das Ciências Sociais. É nesse contexto que surge este volume, o qual reúne textos apresentados e debatidos no âmbito do seminário internacional intitulado “Pós-democracia, género e criminalidade global: aproximações tecnopolíticas desde os movimentos do Sul global”, realizado a 22 de janeiro de 2018 na Faculdade de Economia da Universidade de Coimbra, em resultado da parceria CES com a Universidade de Sevilha, Instituto Joaquín Herrera Flores e CLACSO
