The problem of knowledge dissemination in social network discussions
Full text linkThis paper adopts an Austin-based speech-act theoretical framework to examine how, and to what extent, public social network discussions can contribute to the dissemination of knowledge. We focus on the role of Verdictives, the group of illocutionary acts which consist in the issuing of a judgment, and argue that the knowledge resulting from a Verdictive depends on its bringing about its characteristic conventional effect. Against this background, and working from a corpus consisting of comments on two Facebook posts discussing the highly debated issue of vaccinations, we analyze how knowledge dissemination can take place in social network discussions through the performance of Verdictives and other moves aimed at supporting, rejecting or challenging them. Particular attention is paid to moves aimed at legitimizing or delegitimizing participants as addressers of Verdictives and their sources of information. We conclude from our analyses that Facebook users have their implicit folk-epistemology, but that certain ‘bad habits’ in their communicative behavior and some limitations in their attitude towards inquiry, as well as the negative influence of their search for affiliative relations, significantly limit their possibilities of exchanging and disseminating genuine knowledge

Identità e linguaggio discriminatorio nei social network
Full text linkSocial networks pose new problems in the study of communication, while also amplifying old ones. In this paper we assess the role that the identity of users plays in guiding their readers towards the correct interpretation of their apparently discriminatory uses of language on social network such as Facebook and Twitter: in particular, we focus on non-derogatory uses of slurs on the one hand, and apparently discriminatory irony and humor on the other hand. In these cases, the user’s identity plays a crucial role in the interpretation of the content conveyed by her utterance: to lose track of it may dramatically change the intended meaning, as well as, in some cases, question the legitimacy of her ironic and humoristic uses of language in relation to issues such as racial and gender discrimination. Moreover, the fact that the identity of the writer is hard to pin down poses serious challenges to the issue of censorship: to develop specific policies – which is of the highest importance in managing social networks – requires addressing many theoretical as well as practical issues that we tried to illustrate in this paper
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
