Il cinema non-fiction della Grande guerra italiana, tra propaganda e mercato. Produzione, distribuzione, circolazione
Full text linkNella tesi è stato ricostruito il ruolo ricoperto dagli enti ministeriali italiani preposti alla propaganda durante il corso della Grande guerra, nell’organizzazione della propaganda cinematografica svolta tramite i “dal vero” girati al fronte dalla Sezione Fotocinematografica dell’Esercito. In particolare è stata analizzata l’attività dei seguenti organi: il Ministero senza portafoglio per la Propaganda Interna ed Estera, di Vittorio Scialoja, il Commissariato Generale per le Opere Federate di Propaganda Interna e il Commissariato Generale per l’Assistenza Civile e la Propaganda Interna, entrambi affidati a Ubaldo Comandini, e, infine, il Sottosegretariato di Stato per la Propaganda all’Estero e per la Stampa, diretto da Romeo Adriano Gallenga Stuart. Il lavoro è stato condotto attraverso l’esame di cospicui fondi d’archivio pressoché inesplorati, in precedenza, dagli storici del cinema. L’analisi di tale materiale ha permesso di tracciare un quadro dell’economia del film di guerra.
Da una parte, sono stati messi in luce, infatti, gli sforzi produttivi attraverso cui le istituzioni sostennero l’attività della Sezione Fotocinematografica dell’Esercito, mettendo a disposizione di quest’ultima la pellicola necessaria alla realizzazione dei filmati e finanziandone l’operato. A latere di tale indagine è stato sottolineato anche l’intervento dello Stato nell’ambito della propaganda svolta attraverso importanti film di fiction.
Dall’altra, sono state ricostruite nel dettaglio le politiche di gestione della distribuzione, da parte degli enti ministeriali italiani, dei “dal vero” della Grande guerra, sia sul territorio nazionale che nei diversi Stati europei ed extraeuropei. Tale analisi ha permesso di cogliere come, a differenza di quanto avvenne negli altri Paesi belligeranti, in Italia si tentò di diffondere le immagini filmiche della guerra senza che l’operazione gravasse sul bilancio dello Stato.
Ciò che è emerso con forza, dallo studio delle fonti, è che gli enti pubblici italiani cercarono sempre di vendere i filmati di propaganda, alle ditte concessionarie, alle condizioni più vantaggiose possibili, nonostante da più parti si manifestasse il bisogno di una divulgazione gratuita delle pellicole stesse, al fine di favorire una maggiore circolazione di tali prodotti, poco apprezzati dal pubblico e dagli esercenti.
La tesi sostenuta è dunque che, nonostante la volontà, da parte dello Stato, di trovare una mediazione tra le finalità della propaganda e l’esigenza di un’oculata gestione dei costi, i due termini della dialettica rimasero costantemente in un rapporto conflittuale. In tal senso, la politica adottata dagli organi governativi ebbe, malgrado le intenzioni, un peso notevole nel determinare la limitata circolazione che i “dal vero” italiani della guerra fecero registrare
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
Unresectable hilar cholangiocarcinoma: combined percutaneous and radiotherapic treatment
No full textPurpose: To evaluate, in patients with inoperable hilar cholangiocarcinoma (CLCA), the efficacy of multimodality treatment (brachytherapy, chemotherapy, external radiotherapy and endoprosthesis positioning) in terms of survival, quality of life and cost/benefit compared to palliative surgical treatment.
Material and methods: 11 of 21 patients with inoperable hilar CLCA were enrolled in the following protocol: percutaneous cholangiography followed by positioning of right and left internal biliary drainage (10-12 F); intraductal brachytherapy (7 Gy); the biliary drainages were then replaced by endoprosthesis (12-14F) and left in position for 3 months; external radiotherapy starting 15 days after last brachitherapy; chemotherapy (5 FU) for 5 days; biliary endoprosthesis were removed by endoscopic or transhepatic mode. Follow-up was by: hepatic lab work-up, tumoral markers, US or CT evaluation. Results: 6 patients completed the protocol and 5 were treated only with brachytherapy. All patients had initial complete remission of jaundice. No acute complication was observed. Digestive hemorrhage was the cause of death in 1 patient.
Conclusion: Mean survival was 10.5 months instead of 1.75 months of only percutaneous drainage. The average hospitalization was 10-15 days instead of 15-20 days for palliative biliary-digestive deviation, being less invasive and thus associated with lower morbidity and no mortality. This approach should improve the efficacy of the proposed protocol in terms of quality of life and surviva
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
