Rete e servizi: tra criticità e scenari futuri
Full text linkNel periodo di lockdown, che abbiamo di recente vissuto, le tecnologie digitali sono state fondamentali per il lavoro da casa, per lo svago, per la comunicazione e la condivisione delle esperienze, di fatto per aiutarci ad andare oltre il lockdown stesso. Queste tecnologie, già molto presenti nella nostra vita, hanno assunto un ruolo così fondamentale in modo improvviso e senza alcuna pianificazione preventiva, sia a livello tecnico sia a livello gestionale. Il fatto che le cose abbiano funzionato, è già di per sé un risultato notevole, che merita un’analisi attenta. In questo articolo proponiamo vari spunti di analisi, chiarendo innanzitutto l’importante distinzione fra rete e applicazioni. Sottolineeremo come queste due componenti rappresentino ecosistemi distinti che obbediscono a regole e dinamiche disgiunte e come sia necessario prevedere in futuro chiare politiche capaci di governare in modo chiaro gli obiettivi per cui queste tecnologie vengono dispiegate quando diventano centrali nella vita dei cittadini, cosa non avvenuta appieno fino ad oggi.During the recent lockdown period, digital technologies have played a fundamental role. They freed us from a significant part of the lockdown constraints, by enabling smart working, keeping social connections alive, and allowing us to share our feelings and experiences. These technologies were already pervasive, but the pandemic crisis elevated them to a key factor in our lives in an instant, with no prior technical or management planning. The simple fact that in the end everything just seemed to work is a non-trivial outcome. It is worth a detailed analysis. In this paper, we offer some leads, starting from the important distinction between network infrastructure and services. We highlight that these two components represent ecosystems ruled by different dynamics. We claim that, for the future, well-defined goals should be set for the adoption of these technologies, which play such a central role in citizens’ lives, and effective policies are needed to keep their deployment aligned with said goals, unlike what has happened until now
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
