Aborda o assunto das fake news e sua mais atual evolução, as deepfakes. Adota-se a pesquisa quantitativa para determinar se e como os adolescentes e jovens validam a informação obtida através das mídias sociais. Dentre os objetivos do estudo destacam-se: identificar a utilização das mídias sociais como fonte de informação pelos adolescentes e jovens e o porquê eles as utilizam; descrever o processo de avaliação da informação nas mídias sociais à luz dos critérios propostos pela IFLA; e verificar o nível de confiança do público estudado quanto à identificação, à avaliação e à disseminação de fake news. Conclui-se que, embora não seja de forma satisfatória, os adolescentes e jovens validam a informação obtida através das mídias sociais, evidenciando a necessidade da competência infocomunicacional na formação destes usuários.The research addresses the theme of infocommunicational competence of adolescents and young people in social media. It brings the concepts of information sources, social media and competencies, going through the information and communication competences until converging into the infocommunicational competence. It addresses the subject of fake news and its latest evolution, deepfakes. Quantitative research is adopted to determine if and how adolescents and young people validate information obtained through social media. The objectives of the study include: identify the use of social media as a source of information for adolescents and young people and why they use them; describe the process of evaluating the information on social media in based on the criteria proposed by IFLA; and verify the level of confidence of the target public regarding the identification, evaluation and dissemination of fake news. It is concluded that, although not satisfactorily, adolescents and young people validate the information obtained through social media, highlighting the need for infocommunicational competence in the training of these users
Critérios de avaliação da informação e a correlação com o uso da informação por adolescentes e jovens
Get PDFA pesquisa pretende identificar se os critérios de avaliação da informação que os Adolescentes e Jovens (AJ) utilizam nas mídias sociais encontram correlação com a literatura científica da Ciência da Informação (CI). Ela traz os conceitos de avaliação da informação, competências infocomunicacionais, fontes de informação e mídias sociais. Com a temática avaliação da informação na CI tendo as mídias sociais como fonte de informação, a pesquisa, de cunho quantitativo, tem como objetivos: levantar, na literatura científica da CI, critérios de avaliação da informação; identificar os critérios de avaliação da informação utilizados pelos AJ nas mídias sociais; e analisar a relação entre os critérios empregados pelos AJ e os critérios da literatura científica da CI. Foram identificados 18 critérios de avaliação da informação na literatura científica da CI e 12 foram apontados pelos AJ como critérios utilizados e correlatos com a literatura. Foi possível identificar que todos os 18 critérios da literatura são utilizados pelos AJ, mesmo que em menor grau.The research intends to identify whether the criteria for evaluating the information that Adolescents and Young People (AY) use in social media are correlated with the scientific literature of Information Science (IS).

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
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
