Wittgenstein e Bergson
Get PDFNeste artigo, retomamos a aproximação feita por Pariente entre Bergson e Wittgenstein, e procuramos indicar como ela poderia ser prolongada, em novas bases, por meio dos textos de Wittgenstein de 1929/30 dedicados à questão do tempo. Comentadores como Denis Perrin já notaram a relevância da reflexão wittgensteiniana acerca do tempo para a questão do abandono, por parte de Wittgenstein, do projeto de uma linguagem fenomenológica. Não obstante, creio que não foram inteiramente explicitadas as razões que levaram Wittgenstein a esse abandono. O núcleo desse artigo consiste numa breve análise do capítulo sete das Philosophical Remarks, na qual procuromostrar que a chave daquela questão se encontra no uso, por parte de Wittgenstein, do conceito bergsoniano de um tempo da experiência imediata concebido como "heterogêneo", em contraste com o tempo "homogêneo" da física. AbstractThis paper is an attempt to reassess Pariente\u27s thesis concerning the similarities between Bergson and Wittgenstein. We argue that the thesis can be given an enlarged basis when we consider the texts written by Wittgenstein in 1929-30 dealing with the problem of time. The relevance of Wittgenstein\u27s reflections on time for the dismissal of the project of a phenomenological language has already been noticed by authors like Denis Perrin. Nevertheless, I think they do not provide all the reasons which led Wittgenstein to abandon that project. I offer a brief analysis of Chapter 7 of the Philosophical Remarks, trying to show that a central clue to this issue is to be found in Wittgenstein\u27s mention of the Bergsonian concept of a "heterogeneous" time (the time of immediate experience), as opposed to the "homogeneous" physical time
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
Nota sobre infinito atual e forma lógica no Tractatus
No full textParece haver quase um consenso, entre os comentadores, em torno da tese segundo a qual o “primeiro Wittgenstein” nada veria de problemático na ideia de um infinito atual, ao contrário do que claramente ocorre com o “segundo Wittgenstein”. O que eu gostaria de fazer aqui não é tentar reverter esse veredicto, mas sugerir que o exame das provas que o sustentam merece ser refeito. Para tanto, começarei por tentar mostrar como a letra dos aforismos 5.526 e 5.5262 parece levantar uma dificuldade para a tese consensual. Em seguida, procurarei encontrar, sob a letra, o espírito dessa dificuldade, isto é, buscarei nos princípios mais básicos do Tractatus as razões que subjazem às afirmações desses aforismos. Para finalizar, após fazer um balanço desse exame no que diz respeito à tese consensual, procurarei mostrar como ele aponta para a relevância da notação para o infinito, que João Vergílio Cuter prescreve para o Tractatus
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
