The National Monument in memory of Francesco Baracca in Lugo di Romagna (Ravenna, Italy): materials, techniques and conservation aspects.
Get PDFThis poster will briefly report the results of scientific analyses made on the National
Monument inmemory of Francesco Baracca (a captain of the Italian air force), located in Lugo
di Romagna (Ravenna, Italy). Created by the artist Domenico Rambelli in 1936, this Monument
is considered to be one of the most relevant icons of monumental Italian 20th century
architecture. The whole structure has an extension of 1.040m2 and it is an assembly of: a
stepped base, a colossal airplane wing and a bronze statue, representing the aviator, standing
on a cylindrical pediment. Excluding the statue, theMonument is entirelymade of Travertine.
Scientific analyseswere directed to support the first significant restoration work (held in 2014)
concerning the Monument. Firstly, a preliminary naked eye observation was combined with
mineralogical (XRD) and chemical (micro-chemical spot tests) analyses to localize and
characterize the degradation pathologies affecting the surfaces, indicative of ongoing
phenomena. Then, a multi-analytical approach (RLM, SEM/EDS, μ-FTIR) permitted to
characterize the materials and techniques used by the artist to obtain different kinds of
surface finishing, emphasizing specific parts of the Monument so to achieve well-defined
optical effects. Finally, VIS-RS, RLM and SEM/EDS investigations were performed to evaluate
the application of a surface coating recently introduced and tested in the field of Cultural
Heritage, the titanium dioxide in nanoparticles. In conclusion, the project, besides being a
valuable support for the restoration, represented an occasion for studying an eminent artistic
product of an epochal monumental architecture, symbol of recent history now deserving a
renewed attention
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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
indagine microsismiche ad ultrasuoni capitelli teodoriciani
No full textanalisi complementare per l' intervento di consolidamento strutturale
Proposta di elaborato:
Il restauro dei capitelli teodoriciani è stato ampiamente commentato e documentato, per cui visto che l'intervento di restauro è stato eseguito nel 1995, ritengo interessante valutare le vostre proposte di manutenzione e di verifica sullo stato di conservazione attuale
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
