    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    O presente artigo tem como objetivo analisar a composição da riqueza de três grandes famílias possuidoras de um grande contingente de cativos, terras e prestígio social, da Vila de Santo Antonio do Juiz de Fora, grande plantation cafeeira, localizada na Zona da Mata Mineira, durante o século XIX e que são representativas dos grandes fortunas daquela região. Notamos que as ditas famílias utilizaram-se de estratégias de casamento endogâmicos, objetivando, dentre outras, coisas a manutenção/ ampliação de suas posses, riqueza e poder. Da mesma forma, pudemos notar que a maior parte de suas fortunas concentrava-se em escravos, terras, dívidas ativas. Apesar do prestígio e fortuna, alguns dos indivíduos pertencentes àquelas famílias sofreram um revés financeiro sem volta

    Variations on the Author

    “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

    We 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

    Alforrias e tamanho das posses: possibilidades de liberdade em pequenas, médias e grandes propriedades do sudeste escravista (século XIX)

    O objetivo deste artigo é empreender uma análise acerca das possibilidades de alforria em pequenas, médias e grandes posses de escravos, localizadas em Juiz de Fora (MG), Zona da Mata Mineira, no século XIX. A partir do intercruzamento de fontes concernentes a três grandes famílias possuidoras de escravos, pudemos perceber que a maioria das alforrias distribuídas aos cativos não se deu necessariamente por meio da carta de alforria, sendo também muito importantes as manumissões em testamento e no decorrer do inventário, além das distribuídas em outras situações. Percebemos que os três grandes proprietários de cativos estudados alforriaram proporcionalmente mais cativos do que os pequenos e médios. Houve, portanto, em Juiz de Fora, uma correlação inversa entre o tamanho das posses e as percentagens de alforria "concedidas" por pequenos, médios e grandes senhores escravistas.</jats:p
