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
Construção do ethos de resistência jornalística na imprensa alternativa durante a ditadura militar brasileira: estudo dos depoimentos do projeto Resistir é Preciso
No full textThis thesis aims to analyze the testimonies of the journalists interviewed in the Resistir é Preciso project. In this sense, the research interprets the dispositions, values and representations of these agents from the perspective of a journalistic ethos of resistance in opposition to the dominant positions in the journalistic field. The analytical corpus consists of six testimonies - from Bernardo Kucinski, Elmar Bones, Maria Rita Kehl, Omar de Barros Filho, Raimundo Pereira and Ziraldo – provided for the production of the teledocumentary of the project, exibited in ten episodes on TV Brasil. The criteria for choosing the professionals in question is the prominence of these agents in relation to their performance in the main alternative newspapers of the dictatorial period (KUCINSKI, 2018). Conducted by the Vladimir Herzog Institute, Resistir é Preciso is a broad and multifaceted project to reconstruct memory about the Brazilian military dictatorship. The interviews used for the purpose of carrying out this work were granted in full by the Vladimir Herzog Institute. From a structural point of view, the work starts from the methodological instances instituted by Lopes (1997) for the construction of scientific research in Communication. In an epistemic-theoretical perspective, the research uses two subdivisions: 1) the conceptual keys derived from Pierre Bourdieu's Theory of Practice, as well as from his commentators and authors in the field of Social Communication who carry out interlocutions with the Bourdieusian theory; 2) the discussion of a historiographical character that analyzes the social space that structured the objective conditions for the agents of the alternative press during the dictatorship period. From a methodical-technical point of view, in interlocution with the previous instances, the work will draw on Bourdieusian thinking, based on the relational tools provided by the author, and a description of the main reports of the statements that relate to the problem of this research is carried out. understand the individual dispositions of these agents, their capital configurations and the strategies used. Then, with the analysis of individual character, a comparison will be made between the ethos of different agents to map their objective relationships as a group to observe the operationalization of a resistance journalistic ethos. What is intended is to understand the position of these agents in the journalistic field in a broader way from the analysis of their relationships as a group from the understanding of their common practices and experiences. As a result, it appears that the journalistic ethos of resistance of the alternative press in the Brazilian military dictatorship based on the testimonies of the six agents whose testimonies were studied can be analyzed from the perspective of four analysis categories: 1) Feeling of insufficiency with the press conventional; 2) Contestatory provision; 3) Opposition to the traditional organizational structure; 4) Communication strategies. The journalistic ethos of resistance, therefore, is ultimately a set of provisions, practices and representations of journalists who worked in the Brazilian military dictatorship in order to maintain the autonomy of their field and avoid equipping different social universes through an authoritarian speech.Esta dissertação tem por objetivo realizar uma análise dos depoimentos dos jornalistas entrevistados no projeto Resistir é Preciso, realizado pelo Instituto Vladimir Herzog. Nesse sentido, a pesquisa interpreta as disposições, valores e representações desses agentes sob a ótica de um ethos jornalístico de resistência em contraposição às posições dominantes do campo jornalístico e do campo do poder durante a ditadura militar brasileira. O corpus analítico é composto por seis depoimentos – advindos de Bernardo Kucinski, Elmar Bones, Maria Rita Kehl, Omar de Barros Filho, Raimundo Pereira e Ziraldo – fornecidos para a produção do teledocumentário homônimo ao projeto, exibido em dez episódios na TV Brasil. Os critérios para a escolha dos profissionais em questão remetem à proeminência desses agentes em relação à atuação nos principais jornais alternativos do período ditatorial (KUCINSKI, 2018). Resistir é Preciso constitui um projeto amplo e multifacetado de reconstrução da memória sobre a ditadura militar brasileira. As entrevistas utilizadas para fins de realização deste trabalho foram concedidas na íntegra pelo Instituto Vladimir Herzog. Do ponto de vista estrutural, o trabalho parte das instâncias metodológicas instituídas por Lopes (1997) para a construção de pesquisas científicas em Comunicação. Em uma vertente epistêmico-teórica, a pesquisa se vale de duas subdivisões: 1) as chaves conceituais oriundas da Teoria da Prática de Pierre Bourdieu, assim como de seus comentadores e autores do campo da Comunicação Social que realizam interlocuções com a teoria bourdieusiana; 2) a discussão de caráter historiográfico que analisa o espaço social que estruturou as condições objetivas para os agentes da imprensa alternativa no período da ditadura. Do ponto de vista metódico-técnico, em interlocução com as instâncias anteriores, o trabalho se vale do pensamento bourdieusiano a partir das ferramentas relacionais fornecidas pelo autor. Realiza-se uma descrição dos principais relatos dos depoimentos que tangem à problemática desta pesquisa para compreender as disposições individuais desses agentes, suas configurações de capital e as estratégias utilizadas. Com as análises de caráter individual, efetiva-se uma comparação entre os ethos de diferentes agentes para mapear suas relações objetivas enquanto grupo para se observar a operacionalização de um ethos jornalístico de resistência. Como resultados, infere-se que o ethos jornalístico de resistência da imprensa alternativa na ditadura militar brasileira, com base nos depoimentos dos seis agentes, pode ser analisado sob a ótica de quatro categorias de análise: 1) Sentimento de insuficiência com a imprensa convencional; 2) Disposição contestatória; 3) Oposição à estrutura organizacional tradicional; 4) Estratégias comunicacionais. O ethos jornalístico de resistência, portanto, trata-se de um conjunto de disposições, de práticas e de representações dos jornalistas que atuaram na ditadura militar brasileira com objetivo de manter a autonomia de seu campo e evitar aparelhamento dos diferentes universos sociais por práticas e discursos autoritários
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
