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
Ontologías envueltas: conceptos y prácticas sobre los envoltorios de tejido entre los mayas
No full textAbstract: Objective/context: In this article I propose to analyze the sacred wrappings and the concept of wrapping among the Maya, based on the use of the ontological theoretical framework present in anthropology and archaeology. Two examples of a possibility of such an approach are presented for the study of the textile wrappings present in the Mayan and Mesoamerican territories, from the concept of relational ontologies and by means of native conceptions and theories. With this, we seek to conceptually define the ceremonial bundles based on notions of Mayan thought itself. Methodology: Based on an analysis of ethnographic data, I reflect on the notions of pixan (souls) and pix (wrapping something) in order to approach the concept of wrapping that defines ceremonial bundles. Thus, the two cases that exemplify such reflections are the Martín Bundle, patron and protector of a Tz'utujil community of Lake Santiago Atitlán in Guatemala, and the image of a ceremonial bundle in a scene of enthronement in the Tablero del Palacio de Palenque in Chiapas, Mexico. Conclusions: With the examples presented, I propose to think of the bundles as elements that protect and give a materiality to the pixanes of the other world when they are present in the ordinary world. As such, the wrapping would function as a body for another form of existence in the first example, and as an element of protection for powerful objects, which ends up breeding a relational field between such artifacts as a whole, as presented in the second case. Originality: I hope with this initial reflection to contribute to a discussion about the use of the ontological theoretical framework in the study of archaeological and ethnographic materials in the Mayan area, based on reflections on concepts proper to these peoples.Resumo: Objetivo/contexto: Neste artigo, proponho analisar as envolturas sagradas e o conceito de envolver entre os maias, a partir do uso do referencial teórico ontológico presente na Antropologia e na Arqueologia. São apresentados dois exemplos de uma possibilidade dessa abordagem para o estudo dos envoltórios de tecido presentes nos territórios maias e mesoamericanos, sob o conceito de ontologias relacionais e por meio de conceitos e teorias nativas. Com isso, pretende-se definir conceitualmente os envoltórios cerimoniais a partir de noções do próprio pensamento maia. Metodologia: Com uma análise de dados etnográficos, reflete-se sobre as noções pixan (almas, essências) e pix (envolver algo) para poder se aproximar do conceito de envoltura que define as envolturas cerimoniais. Assim, os dois casos que exemplificam essas reflexões são a envoltura Martín, padroeiro e protetor de uma comunidade tz’utujil do lago Santiago Atitlán na Guatemala, e a imagem de uma envoltura cerimonial em uma cena de entronização no Tablero del Palacio de Palenque em Chiapas, México. Conclusões: Com os exemplos apresentados, propõe-se pensar as envolturas como elementos que protegem e dão materialidade aos pixanes do outro mundo quando estão presentes no mundo ordinário. Dessa maneira, os envoltórios funcionam como um corpo para outra forma de existência, no primeiro caso, e como um elemento de proteção a objetos poderosos que origina um campo relacional entre os artefatos em conjunto, no segundo. Originalidade: Espera-se, com esta reflexão inicial, contribuir para a discussão sobre o uso do referencial teórico ontológico no estudo de materiais arqueológicos e etnográficos no território maia, a partir de reflexões acerca de conceitos próprios desses povos.Resumen: Objetivo/contexto: En este artículo propongo analizar los bultos sagrados y el concepto de envoltura entre los mayas, a partir del uso del marco teórico ontológico presente en la antropología y la arqueología.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Los ancestros Mayas en las mallas cosmopolíticas del período clásico: ontología y poder
No full textEsse estudo discute a presença de importantes ancestrais presentes nas malhas cosmopolíticas maias do período clássico nas terras baixas. Iremos apresentar o papel desses personagens na constituição da pessoa social dos governantes, e na condução política de importantes eventos das sociedades maias daquele momento. Com o uso de conceitos de malhas ontológicas relacionais e cosmopolítica, propomos a existência de um grande emaranhado de relações cosmopolíticas presentes nas cidades maias, no qual os ancestrais tinham um papel protagonista e conviviam lado a lado com seus herdeiros, o que anulava a morte biológica daqueles atores. Com isso, discutiremos de que maneira tais malhas eram estabelecidas e que tipos de relações sociais eram criadas por esses diferentes atores.Este estudio discute la presencia de importantes ancestros en las mallas cosmopolíticas mayas del período clásico en las tierras bajas.
