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
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
Emprendimiento económico: Elementos teóricos desde las perspectivas de sistemas y redes
No full textEl objetivo del artículo es describir los elementos del emprendimiento económico, a partir de las relaciones teóricas proporcionadas por el enfoque de sistemas y redes, como el fin de develarlos en la dinámica del emprendedor y sus acciones. El diseño de investigación es no experimental � documental, con un tipo de estudio descriptivo. Se consultaron diversidad de textos y artículos científicos que centran su foco de estudio en el emprendimiento, para sistematizar desde la teoría la red las características y relaciones que permiten comprender el emprendimiento en el desarrollo económico local. Como resultados destaca como las relaciones sistémicas, y a su vez reticulares, inciden en los emprendimientos empresariales y su sostenibilidad económica, dado la generación de adecuados niveles la confianza y reciprocidad, para promover las formas de asociatividad entre los individuos, creando nuevas empresas que se integran y expanden en los espacios locales. El fortalecimiento de los programas de apoyo al emprendimiento en el diseño de las políticas públicas para el desarrollo local pasa por propiciar y fortalecer las redes de relaciones que emergen de la teoría y que otorgan fortaleza a este tipo de iniciativas en la práctica
¿Cómo realizar un planteamiento del problema de investigación de forma eficaz?
No full textThe chapter aims to guide the researcher in preparing the problem statement for a thesis, at any level. To do this, it was leveraged on the documentary review of recognized authors in the area and on the research experience of the authors of the document. As a result, a structure-guide is presented that, supported by precise and concrete concepts, aims to take the researcher step by step through a commented example, for each of the elements to be considered and included. On the one hand, it offers a tool to evaluate the approach of a thesis work, with which you can practice and master the art of its preparation. On the other hand, suggestions are proposed for the writing and structuring of the document, applicable not only to this section, but to the rest of the sections of the thesis.El capítulo tiene como objetivo, guiar al investigador en la elaboración del planteamiento del problema de una tesis, de cualquier nivel. Para ello, se apalancó en la revisión documental de autores reconocidos en el área y en la experiencia de investigación de los autores del documento. Como resultado, se presenta una estructura-guía que, soportada en conceptos precisos y concretos, pretende llevar al investigador paso a paso a través de un ejemplo comentado, por cada uno de los elementos a considerar e incluir. Se ofrece, por una parte, una herramienta para valorar el planteamiento de un trabajo de tesis, con la cual se podrá ejercitar y dominar el arte de su elaboración. Por otra parte, se proponen sugerencias para la redacción y estructuración del documento, aplicables no solo a este apartado, sino al resto de los apartados de la tesis
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
