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

Riuso architettonico e fragilità
No full textLa ricerca PRIN 2022 dal titolo La governance per la reticolarità montana: co-progettazione ed attivazione di un ‘contratto d’abitare’ per la rigenerazione territoriale della Valle Seriana (UniBG, Polimi) si fonda su un dispositivo giuridico innovativo che consente la realizzazione di progetti di riuso partecipati, finalizzati al potenziamento dei servizi al cittadino. In questo ambito è stata sviluppata una strategia di contrasto all’abbandono, fondata sull’idea di reticolarità tra sistemi montani e di massiccio, a cui si lega la formulazione di azioni di riuso architettonico, intese quali cura e riattivazione del territorio. Gli ambiti di trasformazione toccati dalle strategie progettuali ed illustrati dalla tavola sono: l’antico maglio abbandonato di Ponte Nossa e il sistema ambientale ad esso connesso; l’ex laveria delle miniere della contrada Riso (Gorno); le stazioni ferroviarie abbandonate di Ponte Selva e Clusone e il tracciato dismesso, trasformato in pista ciclabile
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
A rare case of Calot’s triangle paraganglioma
No full textBackground: Paraganglioma is a rare type of neuroendocrine tumor with the ability of neuropeptide and catecholamine secretion. The most common locations of these neoplasms are head and neck regions, retroperitoneal para-aortic and paracaval, renal, and urinary bladder sympathetic plexuses; abdominal paragangliomas at other sites are extremely uncommon. Case presentation: A 66-year-old male patient was admitted to our institution with a diagnosis of an infundibular pericholecystic mass. Laparoscopic cholecystectomy and pericholecystic mass radical exeresis was performed; histology achieved a diagnosis of paraganglioma located in Calot’s triangle. Conclusion: The report shows an extremely rare case of an extra-adrenal abdominal paraganglioma, successfully managed with a laparoscopic approach
