    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

    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

    Tributação e direitos sociais: A extrafiscalidade instrumento de efetividade

    This work analyzes the possibilities of the taxation be an effective way of densification the principle of the human dignity, in front of the materialization of the fundamental social rights, economical and cultural, so that, with this it can be explored all its possibilities in the building of a Democratic State of Right, in a set where the power of the State comes slowly losing tits capacity of act, because of its called structural crisis. The principal of the human dignity is so umbilicus linked to the Democratic State of Right that is possible that it exists, without the formal consecration of that, once the human dignity needs this pattern of the State to ransom ensured, or deep chased. For this purpose, it is necessary state-owned action effective – apart from the neutrality announced by the individualist liberal pattern – meaning, above all, to reduce the economical and social inequalities, front of the accomplishment of the fundamental rights that are suitable for this purpose. For that, the State has powerful instruments, among them, mainly the use of the extrataxly, hypothesis where the State, by taxation, tries to reach the goals of its being – achievement of the fundamental rights and materialization of the constitutional principles – and it does not only goal to obtain derivative takings – for that, with this, it remains preserved and followed the “human interest” in taxation.O presente trabalho analisa as possibilidades de a tributação ser um eficaz meio de densificação do princípio da dignidade da pessoa humana, mediante a materialização dos direitos  fundamentais sociais, econômicos e culturais para que, com isso, possam ser exploradas todas suas potencialidades na construção do Estado Democrático de Direito, num cenário em que o poder do Estado vem perdendo paulatinamente sua capacidade de ação, em face da sua denominada crise estrutural. O princípio da dignidade da pessoa humana está tão umbilicalmente ligado ao Estado Democrático de Direito que não se pode sustentar que este exista, sem a consagração formal daquele, uma vez que a dignidade da pessoa humana necessita desse modelo de Estado para restar assegurada, ou  intensamente perseguida. Para tanto, faz-se necessário uma ação Estatal efetiva – distanciada da neutralidade apregoada  pelo modelo liberal individualista – no sentido de, sobretudo,  reduzir as desigualdades econômicas e sociais, mediante a  realização daqueles direitos fundamentais que adequadamente  servem a esse fim. Para isso, o Estado dispõe de poderosos  instrumentos, entre quais, principalmente, a utilização da  extrafiscalidade, hipótese na qual o Estado, via tributação, busca atingir os fins de sua existência – realização de direitos fundamentais e concretização de princípios constitucionais – e  não visa apenas à obtenção receitas derivadas – para que, com isso, reste preservado e perseguido o “interesse humano” na  tributação

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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
