Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Turismo em Geoparques: análise dos desafios e potencial do Araripe geoparque mundial da UNESCO
Full text linkEste artigo analisa os desafios e potenciais do turismo no Geoparque Araripe, reconhecido como Patrimônio Mundial da UNESCO. A pesquisa, baseada em entrevistas com gestores e trabalho de campo, destaca a importância da gestão integrada e participativa para o fortalecimento dos onze geossítios. Enquanto alguns geossítios, como a Colina do Horto, atraem milhões de visitantes e enfrentam sobrecarga ambiental, outros carecem de infraestrutura adequada. A colaboração entre setores público e privado é essencial para promover a conservação e o turismo, mas persistem desigualdades na distribuição de investimentos e no engajamento local. Conclui-se que o turismo no Geoparque Araripe ainda não é plenamente integrado, exigindo estratégias para equilibrar conservação, crescimento econômico e inclusão social

No full textDispelling the Myths Behind First-author Citation Counts
Full text linkWe 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

Sustentabilidade Ecológica do Espeleoturismo na Serra da Bodoquena, Mato Grosso do Sul
No full textResumo O presente artigo apresenta uma análise da estrutura e produção do espeleoturismo na Serra da Bodoquena, sob o enfoque do ideário de ecoturismo e da sustentabilidade ecológica. A metodologia de pesquisa incluiu levantamentos documentais e de campo em cavidades naturais turísticas. As discussões apresentam aspectos técnico-metodológicos como caminhos viáveis para um espeleoturismo com princípios ecológicos e conservacionistas. Conclui-se que o espeleoturismo pode se firmar não somente como um segmento, mas também como uma nova forma de se fazer o turismo na Serra da Bodoquena. Para tanto, deve identificar novas possibilidades de procedimentos de gestão e manejo ambiental que possam ir além dos paradigmas e modelos vigentes. Palavras-chave: ecoturismo; espeleoturismo; gestão ambiental; Bonito-MS. Abstract This article presents the results of an analysis of the structure and production of speleotourism at Serra da Bodoquena, based on the precepts of ecotourism and ecological sustainability. The methodology included a survey of documents and fieldwork in natural cavities exploited for tourism. The discussion presents a technical-methodological approach for a speleotourism based on ecology and conservation. The study concludes that speleotourism can be established, not only as a specific market segment, but also as a new kind of tourism in the Serra da Bodoquena. Hence new opportunities for environmental management and control of impacts that may exist beyond the paradigms and current models should be identified. Keywords: ecotourism; speleotourism; environmental management; Bonito-MS. Resumen El presente artículo muestra un análisis de la estructura y producción del espeleoturismo en la Serra da Bodoquena, desde el enfoque de la ideología de ecoturismo y de la sostenibilidad ecológica. La metodología de investigación incluyó investigación documental y de campo en cuevas naturales turísticas. Las discusiones presentan aspectos técnico metodológicos como caminos viables para un espeleoturismo con principios ecológicos y conservacionistas. Se concluye que el espeleoturismo puede consolidarse no sólo como segmento, sino también como una nueva forma de hacer turismo en la Serra da Bodoquena. Para eso, hay que identificar nuevas posibilidades en procedimientos de gestión y de manejo ambiental que logren superar los paradigmas y modelos vigentes.
