SPERIMENTAZIONI DRAMMATURGICHE E RIFIUTO DEL TEATRO.
No full textIl saggio si interroga sui contrastanti giudizi di valore attribuiti al dramma e al teatro dalla coscienza leopardiana nell’età dell’acceso dibattito classico-romantico (cui partecipò a suo modo Leopardi stesso). Da una fase di iniziale entusiasmo tra il 1811 e il 1823, testimoniata dalle note zibaldoniane e soprattutto dalla composizione di due tragedie (La virtù indiana, Pompeo in Egitto) e tre abbozzi drammatici (Maria Antonietta, Erminia, Telesilla), Leopardi passò attraverso una fase di rifiuto (1828) per giungere ad un approdo di sperimentale ibridazione della forma lirica della canzone con la forma drammatica del monologo, illustrata da una serie di appunti e dal Consalvo. Viene, in tal modo, sfatato il pregiudizio della “inettitudine” di Leopardi al teatro, riavvicinando l’atteggiamento del recanatese a quello di altri grandi poeti italiani, come Foscolo e Manzoni, tutt’altro che indifferenti al teatro, semmai ad esso ostili per ansia di riforma o di radicale rinnovamento
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
OMEGA-3 PUFAs AND GUT MICROBIOTA: A PREVENTIVE APPROACH FOR COLORECTAL CANCER
No full textThe influence of diet on the composition of the intestinal microbiota and related pathologies has been known for some time. Some classes of nutriens, such as fatty acids belonging to the omega 3 series, have particular effects on the bacteria that make up the intestinal microbiota. Omega-3 PUFAS affect the gut microbiota in three diferent ways: by modulating the type and abundance of intestinal bacteria, by regulate SCFAs levels, and by alter the levels of proinfiammatory mediators. Throug these modalities, omega 3 PUFAs could be useful for the prevention of intestinal diseases such us colorectal cancer (CRC). The ability of omehga 3 PUFAs to modulate the intestinal infliammatory response, to preserve the integrity bof the intestinal mucosa and to modulate the bacterial composition of the intestine, could be useful as a preventive strategic approach to hinder the development of CRC
