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
La troisième rive: les morts et les sentiments de ceux qui restent parmi les Karajá de Ibutuna
No full textThis research deals with the complexities involving the cases of death by bàtòtàka, a spell of "tying the throat" among the Karajá. The objective is, based on the ethnographic analysis of suicide cases in several indigenous contexts, to approach the specificities surrounding the understanding of these phenomena, in order to produce a discussion about the different meanings, based on the particularities of each context in the light of the cases of the inỹ autocides, Karajá’s self-denomination. Thus, this dissertation is constructed using as a literary and discursive resource the story "The Third Margin of the River" by Guimarães Rosa, and the ethnographic accounts of those who stand before the margin and have to deal with the economy of the various cosmos and inỹ beings, In this context, classical themes to Brazilian indigenous ethnology are addressed, such as: the notion of the person, corporeality, as well as the funerals, destinies reserved for the dead and ritual interruptions in the face of these fatalities, which, in Karajá’s context, give to the dead a destiny seen as awkward. In this way, I developed my work in the Ibutuna village, which is located along the Araguaia River, in the northwest portion of Bananal Island, on the border between Mato Grosso and Tocantins states.Não recebi financiamentoEssa pesquisa trata das complexidades que envolvem os casos de morte por bàtòtàka, feitiço glosado por “amarrar a garganta” entre os Karajá. O objetivo é, a partir da análise etnográfica de casos de suicídio em diversos contextos indígenas aproximar-me das especificidades em torno do entendimento desses fenômenos, para assim, produzir uma discussão sobre os diferentes significados, apoiados nas particularidades de cada contexto à luz dos casos de autocídios inỹ, autodenominação Karajá. Assim, utilizando como recurso literário e discursivo o conto “A Terceira Margem do Rio” de Guimarães Rosa, e os relatos etnográficos daqueles que ficam ante à margem e tem de lidar com a economia dos diversos cosmos e seres inỹ, essa dissertação é construída. Maneja-se, nesse contexto, temas clássicos à etnologia indígena brasileira, tais como: a noção de pessoa, corporalidade, assim como as exéquias, os destinos reservados aos mortos e as interrupções rituais diante dessas fatalidades, que, no contexto Karajá, reservam aos mortos um destino tido como torpe. Desse modo, apoio-me no trabalho que desenvolvo na aldeia Ibutuna, que está localizada ao longo do Rio Araguaia, na porção noroeste da Ilha do Bananal na divisa entre Mato Grosso e Tocantins para a construção desse trabalho
Dispelling 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
“A letra é a mesma, mas a cultura é diferente”: a escola dos Tupinambá de Olivença
No full textIn this dissertation, we aim at understanding how and why the Tupinambá from Olivença make school and how this school has become central in the production of strong people in the culture, update and production of kinship, being a relative and being in the culture, as they usually assert. Thus, we were interested in thinking how being in the culture and becoming strong in the culture are being produced from the school and the relationships enabled and coordinated by it, both internally and externally, in the movement that multiplies the school on the Indigenous territory, especially by the reclaimed areas, in order to understand this multiplier effect that relates to politics among the Tupinambá. This happens because, among these Indigenous people, making school, playing politics, claiming, producing reclaimed schools, being in the culture, producing culture, all these update and produce identity, kinship, being a relative and being smart people.Não recebi financiamentoNesta tese, buscamos compreender como e por que os Tupinambá de Olivença fazem escola e do como esta tem se tornado central na produção de pessoas fortes na cultura, na atualização e produção de parentesco, aparentamento e no estar na
cultura, como costumam afirmar. Dessa forma, interessou-nos pensar como o estar na cultura e tornar-se forte na cultura vão sendo produzidos a partir da escola e das relações que esta possibilita e articula, tanto interno quanto externamente, no movimento que multiplica a escola pelo Território Indígena, em especial pelas áreas de retomadas, no sentido de compreender esse efeito multiplicador que se relaciona ao fazer política entre os Tupinambá. Entre os Tupinambá, fazer escola, fazer política, fazer retomada, produzir escolas em retomadas, estar na cultura, produzi cultura, atualizam e produzem identidade, parentesco, aparentamento e pessoas sabidas
Os Xikrin do Bacajá e a Usina Hidrelétrica de Belo Monte : uma crítica indígena à política dos brancos
No full textThe Xikrin Bacajá live "the era of impacts" since the resumption of the licensing process and construction of the hydroelectric plant of Belo Monte. Ngô beyêt is as they call the dam, "standing water, water locked" and expand the meaning of the term for "rotten water, dirty water, old water." In order to strengthen this image of Belo Monte, the thesis presents an ethnographic description of the Xikrin criticism regarding of the white policy in three of its elements: meeting, document, project. The negative elements of the white policy are treated analytically as artifacts being opposed to the forms of existence valued by Xikrin kukràdjà, Mẽbengôkre culture. The contrastive analysis, as well as an important methodological procedure was a widely used resource by Xikrin to express their criticism of the policy of the whites. The contrast images became argumentative form of the thesis, justifying its division into two parts. The analogy by contrast also aims to highlight the image that Xikrin wanted to convey to white of Belo Monte, as a collective of people who share correct and beautiful ways of acting and being in the world. Thus, the depreciation of the white policy will be presented from the appreciation of the Xikrin mode of existence, kukràdjà, the culture of Mẽbengôkre, emphasizing its importance summarily ignored by white of Belo Monte.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Os Xikrin do Bacajá vivem “a era dos impactos” desde a retomada dos processos de licenciamento e construção da Usina Hidrelétrica de Belo Monte. Ngô beyêt é como eles chamam a barragem: “água parada, água trancada” e ampliam a significação do termo para “água podre, água suja, água velha”. Com o intuito de fortalecer essa imagem de Belo Monte, a tese apresenta uma descrição etnográfica sobre a crítica Xikrin à política dos brancos segundo três de seus elementos: reunião, documento, projeto. Os elementos negativos da política dos brancos são tratados analiticamente como artefatos de modo a se contraporem aos modos de existência valorizados pelos Xikrin, kukràdjà, cultura Mẽbengôkre. A analogia contrastiva, além de um importante procedimento metodológico foi um recurso amplamente utilizado pelos Xikrin para expressarem suas críticas à política dos brancos. Por este motivo, o contraste de imagens tornou-se a forma argumentativa da tese, justificando sua divisão em duas partes. A analogia por contraste tem como objetivo evidenciar também a imagem que os Xikrin queriam transmitir aos brancos de Belo Monte, como um coletivo de pessoas que compartilham modos corretos e belos de agir e estar no mundo. Desse modo, a depreciação da política dos brancos será apresentada a partir da valorização do modo de existência Xikrin, kukràdjà, a cultura dos Mẽbengôkre, marcando sua importância sumariamente desconsiderada pelos brancos de Belo Monte
