Piattaforme, sfera pubblica e segretezza
No full textThe subject of this article is the transformation of the public sphere in the age of digital platforms and the implications this has for the democratic life building on Habermas' recent considerations of this change, the political implications and contradictions of the nexus between a normative, hopefully functioning public sphere for democracy, with reason at its center, and a digital public sphere marked by the decline of political life and the difficulty of fragmented networked debate marked by the fading distinction between public and private are analyzed. Habermas' idea is that the perception of the political public sphere is warped by communication on platforms and thus the formation of opinions and political will is in danger. This article analyzes the risks and potentials of the platform society in a diachronic view, addressing the issue of algorithmic secrecy and regulation
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

Advanced endoscopic imaging for the detection and characterization of lesions of the colon: ESGE guidelines
No full textOver the past 15 years many new endoscopic techniques and technologies have been developed that have revolutionized the management of colorectal lesions. The progressive increase in the identification rate of neoplastic lesions of the colon, combined with the possibility of characterizing the lesions to accurately allocate the appropriate treatment, without the need for biopsy and histological examination, have substantially contributed to the reduction of colorectal cancer incidence and mortality. They have also launched endoscopy into a new era. For all these techniques, the potential benefit has to be balanced against the possible financial burden, learning curve, and additional costs. In general, even in the setting of a fully randomised trial, there is a potential bias in the available literature given that it is impossible to blind the endoscopist to the technique that is being studied, and therefore there is always a potential bias in favour of any technique that may affect the performance of the endoscopists, even subconsciously. In this article, we focused our attention on the latest ESGE guidelines, particularly the recommendations and the degree of evidence of the most significant statements on the use of advanced endoscopic imaging for the detection and characterisation of colorectal neoplasia. Furthermore, as these guidelines are the first to address Artificial Intelligence (AI) in endoscopy, we have included a small focus on this in the AI section
