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

Get PDFLa crisis del coronavirus en el 2020 impactó profundamente la economía mundial. El Perú, que contaba con un sector turístico en auge, sufrió especialmente la caída de las llegadas internacionales a su territorio. Para reactivar la economía local, la Municipalidad de Lima lanzó a finales del 2020 una revista digital llamada Visita Lima. El objetivo de este artículo es mostrar cómo un análisis semiótico post-gremasiano puede ofrecer una mirada crítica sobre la oferta de una marca. En este caso, se analizarán los diferentes canales digitales de Visita Lima para luego destacar algunos problemas y finalmente proponer soluciones para que una oferta así sea más clara, relevante y significante
Challenging connotation and denotation with Barthes\u27 mythologies
Get PDFThe problem of the relationship between denotation and connotation, terms introduced in linguistics by Hjelmslev in the middle of the last century, frequently reappears in the semiotic debate. Greimas (1970), Rastier (1987), Klinkenberg (1996) and Badir (2014) have examined the question, offering enlightening, and sometimes opposing, interpretations. Also, Barthes\u27 commentators, such as Eco and Pezzini (1982) or Zenkine (1997), have indirectly contributed to the debate by considering the "mythologies" of the French semiologist as types of connotations. However, as this article will tend to demonstrate, mythologies do not rely on the phenomenon of connotation, but of denotation. Thus, the aim of this work will be to enrich the discussion on these semiotic languages by countering the belief that mythologies are forms of connotation, in other words, by engaging Hjelmslev and Barthes in a dialogue on the question of cultural meanings.La problématique du rapport entre dénotation et connotation, termes introduits en linguistique par Hjelmslev au milieu du siècle passé, resurgit fréquemment dans les débats sémiotiques. Greimas (1968), Rastier (1987), Klinkenberg (1996) et Badir (2014) se sont notamment penchés sur la question, proposant des lectures, si ce n’est opposées, en tout cas à chaque fois éclairantes. Également, les commentateurs de Barthes, tels Eco et Pezzini (1982) ou Zenkine (1997), ont indirectement contribué au débat en considérant les « mythologies » du sémiologue français comme des types de connotations. Or, ainsi que se propose de le montrer cet article, les mythologies s’avèrent non pas ressortir du phénomène de la connotation, mais de la dénotation. Ainsi, l’objectif de ce travail sera d’enrichir la discussion sur ces langages sémiotiques, en contredisant cette croyance selon laquelle les mythologies seraient des formes de connotations, autrement dit, en faisant dialoguer Hjelmslev et Barthes sur la question des significations culturelles
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
Propósito semiótico y perspectivas estratégicas de Visita Lima
No full textThe COVID crisis in 2020 deeply impacted world economy. Peru, which had a boom-ing tourism sector, suffered severely from the fall in international arrivals to its ter-ritory. To reactivate local economy, the Municipality of Lima launched, at the end of 2020, a digital magazine called Visita Lima. The aim of this article is to show how a postgreimasian semiotic analysis can provide a critical look at the offering of a brand. In this case, the different digital channels of Visita Lima will be analyzed in order to highlight some strategic issues and to propose solutions to make such an offering more relevant and meaningfulLa crisis del coronavirus en el año 2020 impactó profundamente la economía mundial.
