Per un calcolo “di qualità”: storia di una sfida qualitativa alla quantificazione, passando per la conoscenza
No full textStarting from the case study of a 16th century palace in Parma, this paper aims to demonstrate how
a careful constructive survey, together with an accurate investigation of the historical evolution of
the building can, in certain cases, avoid the need to resort to invasive mechanical tests for safety
assessment. This challenge is based on the awareness, resulting from a long debate in the academ ic and scientifc felds, of the importance of the ‘knowledge path’ in the analysis of the structural
behavior of historic masonry buildings: the ‘qualitative understanding’ of the building – gained
through the direct and in-depth knowledge of the asset, the constructive features, the proportional
rules, the historical evolution, as well as the experience of recurring damage – is the basis for a
correct evaluation of strengthening interventions and, sometimes, unexpectedly, is even preferable
to numerical data. In fact, it is widely recognized, even in the normative feld, that standard global
modeling procedures and numerical calculations, valid for ordinary buildings, do not always ft
for historic masonry structures, which tend rather to be damaged by local mechanisms. In fact,
the path of knowledge, applied to the case study, which will be illustrated in this paper, allowed to
highlight the main vulnerabilities of the asset and therefore to focus on the direct investigations
only on the elements at risk, for which local interventions will be planned, respecting the principle
of minimum intervention
From the Document to Knowledge: the Constructive History of the Wooden Ring of the Dome of Santa Maria del Fiore|Dal documento alla conoscenza: la storia costruttiva della cerchiatura lignea della cupola di Santa Maria del Fiore
No full textThe paper presents the results of the research recently carried out on the chesnut chain of Santa Maria del Fiore dome, in Florence: probably the less investigated element of Brunelleschi's masterpiece. Thanks to the recent laser-scanner survey of the chain - carried out by the Opera del Duomo in Florence (studio Scaletti, Florence) - it has been possible to reconstruct the history of a really peculiar artifact (for materials and configuration) which always accompanied the debates on the stability of the dome, without ever becoming the protagonist. By comparing the results to historical treatises, the attempt was to date the different constructive elements of the wooden ring, thus enhancing the global knowledge on the dome. The analysis of the detailed notes drawn up by the workers led to localize the interventions on the chain. This allowed to distinguish the original technologies from the further interventions, thus mapping the technical advances that have taken place in the meantime during the centuries. In particular, the investigation carried out on a specific joint (E) aims to demonstrate the validity of a research method, which finds in the monument itself the first document of its complex history

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
