Revisitando MacBride: utopías y distopías
No full textO Relatório MacBride, publicado pela Unesco em 1980, é um marco do desenvolvimento da comunicação em níveis regional, nacional e global. Mas raramente é percebida a sua influência sobre os estudos da área, que pode ir desde a delimitação do objeto de pesquisa até a estimativa de resultados esperados, passando pela definição do corpus. Após 40 anos de sua aparição, o pensamento acadêmico se lançou à tarefa de retomar a apreciação de seu legado. Este livro se situa na esteira desse esforço de reconhecimento histórico da importância do documento, oferecendo abordagens integradas em duas seções: “Contextos e atualidades” e “Cenários aplicados”

Have people ‘had enough of experts’? The impact of populism and pandemic misinformation on institutional trust in comparative perspective
Full text linkPublic trust in institutions is a key prerequisite for effective crisis management. However, the rise of populism and misinformation in recent years made it increasingly difficult to maintain institutional trust. Despite this recognition, we still lack a systematic understanding of how exposure to misinformation and populist political orientation affect people’s trust in institutions. This paper fills this gap by adopting an original approach to trust, focusing on prospective trust rather than trust in the present, and by comparing four countries led by populist leaders during the pandemic – Brazil, Poland, Serbia, and the United States. The comparative design allows us to consider not only the role of individual-level factors (populist attitudes and misinformation exposure) but also the role of different approaches to the COVID-19 pandemic adopted in the four countries. The study utilizes data from a cross-sectional survey, carried out between November and December 2022 (N = 5000). Our findings show that populist attitudes are the most significant predictor of distrust in political institutions in all four countries. Believing in false information related to COVID-19, on the other hand, has a stronger impact on distrust in expert institutions – public health authorities, scientists, and medical professionals. The data also highlight the importance of local context and different approaches to handling the pandemic in the dynamics of trust. In Poland and Serbia, populist voters have more trust in both healthcare authorities as well as in political institutions; however, in Brazil and the United States, populist voters were more likely to distrust expert institutions
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
