«Compiuta l’esplorazione alla presenza del Principe d’Assia». Note su alcuni complessi di età orientalizzante dalla necropoli dell’Osteria (scavi Ferraguti – Mengarelli 1931)
No full textNel giugno del 1931, nel corso delle indagini condotte da Ugo Ferraguti e Raniero Mengarelli nella necropoli dell’Osteria a Vulci, furono scavate due tombe alla presenza di Filippo, Langravio d’Assia-Kassel e marito della principessa Mafalda di Savoia – figlia di Re Vittorio Emanuele III –, in visita a Vulci con il Marchese Giorgio Guglielmi, Vice-presidente del Senato del Regno e proprietario dei terreni nei quali si svolgevano le indagini. Mentre di una tomba si conservano tutti i materiali, dell’altra non risulta alcun oggetto sugli inventari del Museo di Villa Giulia. Una serie di fotografie conservate presso l’Istituto Luce, realizzate proprio in occasione della visita di quell’importante personaggio, ha consentito tuttavia il parziale recupero del contesto. Entrambe le tombe si datano ai primi del VI sec. a.C. e, con altre indagate nello stesso settore nel corso di quelle fortunate indagini, consentono di offrire alcuni nuovi dati su tipi funerari e cultura materiale di Vulci tra età tardo-orientalizzante e alto arcaica

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
Complications of colonic diverticulosis
No full textFrom 1978 to 1993, 220 patients were admitted at the Cl. Chirurgica III of the University of Bologna because of acute colonic diverticulitis. During the same period 108 patients (58 females and 50 males; mean age 65 years) were operated on for complications of the disease; 21 acute diverticulitis, 10 pericolic or pelvic abscess, 30 purulent peritonitis, 7 fecal peritonitis, 19 obstruction, 14 hemorrhage and 7 fistula. Surgical techniques were: resection and primary anastomosis (n. = 46), two or three stage procedure (n. = 49), Hartmann's resection (n. = 13). Mortality rate was 15%, 14,2% and 7,6% respectively. The advantages or disadvantages of the various surgical approaches in relation to the type of complications were evaluated. In conclusion appropriate segmental resection of the colon with or without primary anastomosis is recommended
