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
Keep Fit! Benessere attivo e nuove tecnologie
No full textCosa sta avvenendo nella cultura sportiva oggi? Si nota il passaggio dal modello dello sport competitivo (basato sull’etica del lavoro, sull’efficienza del corpo e sul perseguimento del record), a un’idea di sport come pratica espressiva, come risorsa per l’auto-gratificazione e la ricerca di benessere e di relazioni positive. Il volume raccoglie varie ricerche sulle trasformazioni in atto nei luoghi dello sport. Gli Autori osservano il mutamento sociale e culturale in atto, con particolare attenzione alle trasformazioni che i media digitali favoriscono nel campo dello sport e delle attività fisiche. Il tentativo è quello di far emergere opportunità e rischi, generati dall’uso dei dispositivi digitali nelle pratiche di fitness e wellness in palestra, nelle società sportive e nelle pratiche, anche di gruppo, open air. I contributi presentati convergono nel riconoscere che le pratiche di fitness e wellness sono sempre più social. L’impiego della tecnologia digitale dimostra di avere molteplici ricadute sociali, funzionali allo sviluppo di pratiche vantaggiose per stabilire positive relazioni con gli altri e con la natura. Mantenersi in forma assume una gamma di significati non riconducibili al semplice workout di tipo fisico, palesandosi come un vero e proprio training di carattere sia culturale sia sociale, fortemente sostenuto dalle piattaforme presenti on line. La società in rete così coglie, connette e potenzia le pratiche e i valori ‘post’-moderni, di cui si nutrono milioni di praticanti lo sport e l’attività fisica nel nostro Paese
