Studi, interventi e leggende sul Palazzo Morani-Cantoni
No full textIl testo raccoglie una serie di contributi che documentano lo stato di Palazzo Morani-Cantoni di Prevalle (Brescia) al momento del terremoto della Val Sabbia del 2004 e tutti gli studi ed interventi eseguiti successivamente per l'analisi ed il consolidamento dell'edificio di interesse monumentale. Il testo è completato da alcuni capitoli che testimoniano la vita e la storia del palazzo dalla fondazione (1750 circa) ad oggi
Seismic Behaviour of Masonry Vault-Slab Structures
No full textSpandrel walls typically play a structural role in masonry buildings, transferring load from a slab to the supporting vault. Some indications are given in the literature on the behaviour
of spandrels under the effect of vertical loads, but little attention is given to the effect coming from lateral forces acting on the building. An opportunity to investigate this problem has come
from the need of analyzing a monumental building which was damaged by the Nov. 24, 2004 Val Sabbia earthquake in the north of Italy. The finite element model set up for the analysis of
the vault-spandrel-slab system is presented and the structural role resulting for the spandrels is discussed
Effectiveness of seismic improvement of monumental heritage
No full textNew guidelines for seismic improvement interventions on monuments and heritage buildings were issued in Italy in 2011. Such guidelines are characterized by the introduction of a procedure for evaluating the effects of interventions in terms of the resulting increase of nominal life of the structure. The procedure makes reference to the description of the state of the structure in terms of damage mechanisms. In the work proposed here, the application of this recent procedure to a particular case is the occasion for a study of its sensitivity to the values of the vulnerability parameters adopted. The case examined concerns a church located on a hill crest in the subalpine region of northern Italy, in a low-to-moderate seismic area. The application of the procedure has permitted remarks on the evaluation both of the vulnerability indices associated to the different damage mechanisms and of the reduction of risk consequent to the interventions
Valutazione degli interventi di miglioramento sismico su beni monumentali
No full textNel 2011 sono state emesse le nuove “Linee guida per la valutazione e la riduzione del rischio sismico del patrimonio culturale”, che introducono una procedura per la valutazione degli effetti di interventi di miglioramento sismico in termini di incremento della vita nominale della costruzione. Il metodo si avvale della descrizione dello stato della struttura per mezzo dei meccanismi di danno. In questo lavoro l’applicazione della procedura allo studio di un caso particolare è l’occasione per discuterne la sensibilità rispetto ai valori dei parametri di vulnerabilità impiegati. Il caso esaminato si riferisce ad una chiesa situata in una zona a sismicità medio - bassa dell’Italia del nord. L’applicazione della procedura è occasione per commentare sia la valutazione dei parametri di vulnerabilità associati ai diversi meccanismi di danno, sia la riduzione del rischio conseguente agli interventi
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
