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
Falando de Pronomes
The aim of this article is to discuss the main characteristics of pronouns and to present the Spanish personal pronouns and some of their peculiarities.O artigo apresenta os pronomes pessoais do espanhol em algumas de suas peculiaridades, depois de lembrar qual a característica fundamental das palavras que são chamadas de pronomes
Hablar... hacer. ¿Qué hacemos cuando usamos las formas pronominales?
Resumen El objetivo del trabajo es subrayar el papel de los pronombres en la interacción lingüística. La idea rectoraes la de reflexionar sobre aquello que el hablante consigue comunicar al emplear diferentes formas de los pronombres. Primeramente, se presentan algunos términos que van a ser usados con referencia a la estructura de la información. Se recuerdan las formas de los pronombres personales del español, destacando algunas características que establecen diferencias entre esas formas y posibilitan sus diferentes usos. A continuación se consideran distintos ejemplos con el fin de analizar las funciones de los pronombres en la vehiculización de la información. pragmática, vehicular la información, pronombres, duplicaciones

O trabalho procura conhecer melhor a gramática do português falado no Brasil através do contraste com o espanhol falado no Uruguai. Os dados mostram que onde o PB apresenta o sujeito preenchido, o EU prefere o sujeito nulo, e onde o objeto aparece nulo no PB, o EU prefere o clítico. Enquanto que o PB parece ter evoluído no sentido da perda de certos clíticos, o espanhol falado no Rio da Prata é tido como aquele dialeto com maiores possibilidades no uso da duplicação de clíticos. Esses fatos são conhecidos, mas qual a generalização adequada? O que esses fenômenos revelam sobre as gramáticas dessas línguas? Este trabalho examina diferenças e semelhanças no uso dos pronomes, especificamente, no uso dos clíticos, dirigido pela idéia de que os pronomes clíticos são reveladores de outros fenômenos sintáticos e morfológicos. Na análise sintática aqui proposta, os clíticos são considerados como elementos de natureza D, inseridos, na derivação, no lugar do argumento do verbo, e que se movimentam em adjunção a uma categoria funcional. Os sintagmas duplicadores são considerados adjuntos, e sua ocorrência dirigida por razões discursivasNot availabl
Dispelling the Myths Behind First-author Citation Counts
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
