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
El trinquenio amargo y la ciudad distópica: autopsia de una utopía
No full textIn the recent cultural debate in Cuba, on the subject of the repressive policy of the seventies, the Cuban architect Mario Coyula was an outstanding participant, delivering the presentation that we reproduce here, in which he reflects on the effect of that policy upon Cuban cities and contemporary architecture. That dark decade which damaged so many other intellectual activities, according to Coyula, started even earlier in architecture and is not yet over, being related to increased mediocrity which represses as suspicious any individual creative act.En el reciente debate cultural en Cuba, a propósito de la política represiva de los años setenta, el arquitecto cubano Mario Coyula tuvo una destacada participación, al presentar la ponencia que aquí reproducimos, en la que reflexiona sobre el efecto de aquella política en las ciudades y la arquitectura cubana contemporáneas. Esa década obscura, que dañó tantas manifestaciones intelectuales, según Coyula, empezó antes para la arquitectura y no ha terminado aún, asociada a una mediocridad en ascenso que aplasta como sospechoso cualquier acto creativo individual
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

Housing, Urban Renewal and Popular Power: Some Reflections on Havana
Get PDFCuba is the largest of the Caribbean Islands with an area of more than 110,000 square kilometers and a population that recently reached 10 million inhabitants. Four hundred and fifty years of colonial domination and neocolonial dependence created structural inequalities throughout the territory.At the triumph of the Revolution in 1959, Havana, the capital city, held 20% of the 6 million inhabitants of the country. Located there as well was 75% of the Island's nonsugar-based industry, most port services, health services, education, and tourism. This inequality between the capital city and the rest of the country stimulated heavy migration that resulted in shantytowns of marginal character with unhealthy conditions. These communi ties were not only removed from the lifestyle of all sectors of the bourgeoisie, but also from the proletariat. The latter, with more of an urban tradition, had become entrenched in the dense web of the ancient city center, undergoing the ghettoization that followed the exodus of the ruling classes
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
