Evaluation of structural safety and seismic vulnerability of historical masonry buildings: studies and applications in the Tuscany Region
Full text linkRecent earthquakes in Italian regions evidenced the high vulnerability of historical masonry existing buildings: severe damages were revealed in structural and not structural elements with the following loss of lives and of significative examples of the Italian architectural tradition, often requiring a strong financial effort to be carried back to their ancient brightness. The majority of the Italian buildings' heritage is made up of masonry constructions with high architectural, historical and monumental impact, enlarged over the centuries without an organized scheme and consequently characterized by structural and not structural problems often increased by the loss of an accurate maintenance. The Italian Standards for Constructions and the guidelines provided by the Ministry for Infrastructures for the evaluation and reduction of seismic risk on historical heritage pay a lot of attention towards the vulnerability analysis of existing buildings, necessary for the elaboration of a project providing higher level of structural static and seismic safety without deleting the original nature of the building. In the present work, the structural analyses of two historical masonry buildings, Palazzo La Sapienza in Pisa and Palazzo Ducale in Massa are presented
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
Numerical modelling, analysis and retrofit of the historical masonry building "La Sapienza" in Pisa
Full text linkThe evaluation of the structural safety and seismic vulnerability of historical masonry buildings represents one of the most important problems affecting countries, like Italy, characterized by a wide cultural heritage whose original configuration shall be preserved against unexpected seismic events or insufficient maintenance. Recent earthquakes in the Italian regions (Umbria-Marche 1997, Molise 2002, L'Aquila 2009 and Emilia-Romagna 2012) evidenced the high vulnerability of historical masonry buildings, severely damaged in both their structural and not-structural components (i.e. walls, vaults, domes, arches, ornaments and others) and the following significant economic effort required for the execution of retrofit interventions. According to the actual Italian Standard for Constructions (D.M. 14/01/2008) and to the Guidelines provided by the Italian Ministry for Infrastructures for the evaluation and reduction of seismic risk on historical heritage (2010), a multi-level approach is generally adopted for the assessment of the structural safety and seismic vulnerability of ancient masonry buildings and for the design of retrofit interventions. In the present work, the above mentioned multi-level approach is applied to "La Sapienza" Palace in Pisa (Italy). The building, ancient seat of the University of Pisa, was subjected to a wide in situ structural survey and to experimental testing campaigns (including geotechnical analyses, mechanical characterization of materials, structural monitoring and other) allowing the elaboration of a reliable FEM model used for the execution of structural verifications and for the individuation of the main retrofit techniques able to preserve its original nature providing, at the same time, a sufficient margin of structural safety
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
