Critérios de seleção de notícias em redes sociais na internet: um estudo do perfil noticioso da folha de S. Paulo no Facebook
Full text linkDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Jornalismo, Florianópolis, 2015.Esta dissertação parte da relevância de entender como a notícia se movimenta e ganha forma nas redes sociais na internet. Propõe-se, portanto, a responder a seguinte pergunta: quais são os critérios usados para selecionar uma notícia para circular nas redes sociais na internet (RSIs)? Observações preliminares mostraram que as notícias publicadas nas RSIs, em especial no Facebook, são replicações de conteúdos já postados anteriormente em outras mídias, como portais, TVs, rádios etc., e que ainda não há produção de conteúdo exclusivo para as RSIs. Dessa maneira, limitou-se o objetivo desta dissertação em identificar os critérios de seleção das notícias que já foram publicadas em outros meios para circularem no Facebook. Este site de rede social foi escolhido por ser considerado, entre os demais, o mais utilizado para buscar notícias atualmente. A hipótese inicial era a de que esses critérios de seleção estariam relacionados aos valores-notícia inerentes ao fato jornalístico e também às métricas obtidas a partir dos próprios conteúdos. Os procedimentos metodológicos foram divididos em dois momentos principais. O primeiro, entrevista com o editor de Mídias Sociais da Folha de S.Paulo, que ocorreram em fevereiro de 2015, com o intuito de entender a rotina de trabalho com este site de rede social e as suas percepções sobre os critérios utilizados na seleção de notícias. No segundo momento, uma análise de conteúdo dos posts publicados na página de interesse desta pesquisa, cujo levantamento foi do período de 1º a 7 de abril de 2015, com o intuito de observar a utilização e efetividade dos critérios mencionados, direta ou indiretamente, na entrevista. Esta pesquisa concluiu que há pelo menos três critérios específicos para selecionar notícias que deverão circular no Facebook, denominadas nesta dissertação como  Homepage ,  Métricas e  Percepção do profissional .Abstract : This master thesis is motivated by relevance of understanding how the news circulates and is produced in social networks on the internet. The proposition, then, is to answer the following question: what are the criteria used to select news that will circulate through the social networks on the internet (SNI)? Preliminary observations show that news published on the SNIs, especially on Facebook, are replications of content already published on other media, such as portals, TVs, radios etc., and that there is no production of exclusive content for these sites. Thus, the aim of this master thesis was limited on identifying the criteria of selection of news already published on other media to circulate on Facebook. This social network site was chosen for being, amongst others, the most used one for searching news nowadays. The initial hypothesis was that the selection criteria is related to the news-value inherent of the journalistic fact as well as engagement metrics to this content. The methodological procedures were divided in two main moments. The first, interview with the editor of Social Media of Folha de S.Paulo. On a second moment, an analysis of the posts' content published on this research's page of interest, aiming to perceive whether or not the criteria mentioned were used, direct or indirectly, on the interviews and also its effectiveness for selecting news in this ambient

Formatos hipermidiáticos e redes sociais: apropriações em três webjornais de referência
Full text linkDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em JornalismoEste trabalho tem como objetivo investigar como o webjornalismo de referência está se apropriando das redes sociais da internet (RSIs) no processo de produção da notícia. A partir do reconhecimento de que a produção jornalística contemporânea tem caráter hipertextual, multimídia e interativo, lançamos foco nos estudos acerca de dois aspectos exclusivos do ambiente web - o desenvolvimento de formatos noticiosos com uso da hipermídia e o uso das RSIs pelo jornalismo. Para tal, elegemos três casos pontuais: (1) o especial multimídia Ruta 66, produzido pelo Clarín.com, que apresenta o blog incorporado a sua estrutura, (2) a reportagem multimídia Mumbai: living the dream, produzida pelo FinancialTimes.com com auxílio do Facebook e (3) a infografia interativa The election will be tweeted (and retweeted) produzida pelo NYTimes.com com dados do Twitter. A partir desses casos, foi possível apontar três apropriações diferentes. Nesta investigação, uma pesquisa exploratória com método descritivoanalítico, a convergência, em suas múltiplas faces, é tomada como pano de fundo para os processos aqui analisadosThis study aims to investigate how the reference web journalism is appropriating the social networking (RSIs) in the process of news production. Focusing on studies released about two unique aspects of the web environment - developing news formats with the use of hypermedia and the use of RSIs for journalism. We chose three specific cases: (1) the multimedia special Route 66, produced by Clarín.com, which has the corporate blog of its structure, (2) the multimedia feature Mumbai: Living the Dream, produced by FinancialTimes.com with help of Facebook and (3) the interactive graphics The election will be tweeted (and retweeted) produced by NYTimes.com with data from Twitter. We assume that the different appropriations of social networks can contribute positively to the information reporting. From these cases it was possible to identify three different appropriations.In this research, an exploratory descriptive and analytical method with convergence, in all its facets, is taken as a background for the processes analyzed her
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
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
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
