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
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
Guerra global, sujetos y fronteras: para una semiótica de la geopolítica a través del modelo de Yuri Lotman
No full textThis paper proposes an interpretation of imperialism’s topology based on the semiotic model of Yuri Lotman. We try to explore some of the spatial transformations caused by the occupation and organization of geopolitical strategies from the nineteenth century on. Our proposal is based on Lotman’s fundamental topological model but adds other elements of analysis.Este texto propone una interpretación de la topología del imperialismo a partir del modelo semiótico de Yuri Lotman. Intentamos explorar algunas de las transformaciones espaciales producidas por la ocupación y organización de la estrategia geopolítica desde siglo XIX. Nuestra propuesta se basa en el modelo topológico fundamental de Lotman pero agrega otros elementos de análisis
Cuerpos en acción, artes vivas e interculturalidad
No full textEste texto é ao mesmo tempo um breve compendio do curso sócio-antropologia teatral (Sociologia) y uma proposta complementar para o ensino das artes cênicas. Os aspectos teóricos de base são: a eliminação dos limites e fronteiras epistemológicas e ideológicas entre as áreas disciplinares e artísticas, o manejo da interculturalidade, os princípios da Sócio-antropologia teatral e em especial o conceito de restauração da conduta ordinária e a necessária vinculação de uma teoria do corpo, da ação e da personagem.This text is, at the same time, a brief compendium of the course of socio- anthropology (Sociology) and a complementary background in the learning process of performing arts. The theoretical aspects are: the elimination of limits and epistemological borders between the areas or artistic disciplines, the managing of the inter-cultural process in live arts, the use of the principles in theatrical socio-anthropology and specially ,the concept of conduct-restoration and the connections between an theory of the body, theory of the action and theory of the personage.Este texto es al mismo tiempo un breve compendio del curso de socioantropología teatral (Sociología) y una propuesta complementaria para la enseñanza de las artes escénicas.

Diseño gráfico y semiótica en Venezuela : entre historiografía y teoría
Get PDFEn este trabajo se trata de articular y conectar las producciones del diseño gráfico en el proceso educativo desde una perspectiva semiótica. Al mismo tiempo, se propone una tipología semiótica abierta para realizar nuevos estudios sobre el análisis sincrónico y diacrónico del diseño. Los objetos de diseño gráfico aquí elegidos se colocan entre una teoría semiótica y la historiografía.This paper tries to articulate and connect the productions of the graphic design in the educational process from a semiotic perspective. At the same time, we propose an open semiotic typology for further studies over synchronic and diachronic analysis of design. The graphic design's objetcs chosen here are placed between a semiotic theory and historiography
