Pietre policrome nelle architetture di Genova durante il regime fascista: aspetti di documentazione e rilevamento
No full textDuring the last decades the scientific review of architectural works gradually improved thanks toon-site and non-destructive techniques. Though the historical-critical method of direct analysis of buildings with drawing tools and representation, combined with the archive documents, remains the fundamental approach for any research in architecture, important advantages can derive from the results of chemical, mineralogical, physical, and biological analysis. The “cromia” topic applied to decorative and ornamental lithotypes is strongly growing up in the last times, and requires an objective and scientific approach, instead of a subjective perceprion or visual evaluation. The X-Ray Fluorescence analysis by means of portable instruments (FP EDXRF) supplies a survey based on compositional data of materials, that are the base for developing conservation protocols and restoration projects, and provides a chance for new historiographic and hermeneutics paths
Buildings that ‘Speak’: Ichnological Geoheritage in 1930s Buildings in Piazza della Vittoria (Genova, Italy)
No full textThe geoheritage value of sedimentary building stones has mainly focused on physical sedimentary structures and body fossils. By
contrast, little attention has been placed on the geoheritage significance of ichnofabrics, which are the sedimentary fabrics that
have been reworked by organisms. This study aims to fill this gap by analysing the ichnofabric found on the buildings of Piazza
della Vittoria, in Genova (Italy). Here, unusually visible and well-preserved specimens of the fossil burrow Bichordites are
observed on the historical buildings designed by Marcello Piacentini, one of the local most prominent architects of the 1930s. The
Bichordites of Piazza della Vittoria are winding meniscate burrows with a central string-like structure. Here, we interpret this
ichnofabric as the result of the activity of a community of echinoids bioturbating a sand wave system. We have also located the
historical quarry that provided material for the studied buildings with the same ichnofossils exposed. Surprisingly, the cuts on
display on the buildings are much nicer than those in the outcrops and more taxon specific characteristics can be observed just on
the tiles rather than in the field. For all these reasons, the geoheritage value of the Piazza della Vittoria ichnofabric relies in its
unique scientific significance, the cultural value, and its potential future applications in research, teaching, urban geotourism and
reference site
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
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
