La costruzione moderna a Bologna. Ragione scientifica e sapere tecnico nella pratica del costruire in cemento armato
No full textAll’inizio del Novecento, le Scuole d’Applicazione per gli Ingegneri introdussero in Italia alcuni insegnamenti relativi alla nuova tecnica costruttiva del calcestruzzo armato. Nella Scuola di Bologna si delineò una situazione didattica privilegiata, trovandosi ad insegnare, l’uno accanto all’altro, Silvio Canevazzi, personalità tra le più rinomate nell’ambito della comunità scientifica d’inizio secolo, e Attilio Muggia, uno dei protagonisti del panorama costruttivo nazionale, pioniere nel campo delle costruzioni in cemento armato. Gli autori indagano le vicende relative ai primi decenni di attività della Scuola di Bologna nel campo della ricerca e dell’insegnamento intorno al nuovo materiale, grazie al quale gli ingegneri qui laureati all’inizio del Novecento poterono asservire una tecnica già matura e notevolmente raffinata ad una eclettica mescolanza di linguaggi compositivi
A reinforced concrete stage tower within a 18th-century masonry theater: The Municipal Theater of Bologna
No full textThe Municipal Theater is one of the main artistic symbols of Bologna. Although it is recognized worldwide for its musical history, its construction peculiarities are less known. The original building was designed by the architect Antonio Galli Bibiena in 1763 in a masonry and wood structure. Then, the stage tower, burnt away in 1931, was rebuilt with a reinforced concrete structure, which currently is a significant landmark in the heart of the University district with about 35 m height. The reconstruction project, designed by engineer Armando Villa, had to face complex issues for the emerging but still inexperienced Italian reinforced concrete technique, such as the installation of a large span roof at considerable heights. The archival research and the digital documentation made it possible to analyze the structural concept of this construction, a significant example of the building culture of the '30s, tracing the evolution of this specific construction system and contextualizing it on the international scene
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
Effetti della supplementazione con vitamina E sulla stabilità ossidativa e sul colore della carne di struzzo (Struthio Camelus)
No full textDispelling 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
