Base isolation seismic retrofit of a hospital building in Italy: design and construction
No full textThe paper deals on a significant retrofit project currently under construction of an existing hospital building in Avellino (Italy). The seismic retrofit was realized by connecting the first floor of the three existing structures and creating one only isolation system composed of high damping rubber bearings and sliding devices. The base-isolation is achieved by gradually cutting the building from foundation and installing the isolators at the level of upper edge of the columns. The study allowed the verification of the adequacy of the isolation system, showing the benefits of the application of the isolation devices, the limitations and the characteristics of their performance
Adeguamento sismico di un ospedale esistente mediante isolamento alla base
No full textIl lavoro riguarda l’adeguamento sismico di una struttura ospedaliera esistente mediante la tecnica dell’isolamento alla base. L’edificio, situato nel complesso della città ospedaliera di Avellino, è composto da tre corpi di fabbrica staticamente indipendenti. Il progetto prevede la solidarizzazione degli impalcati del primo livello e la realizzazione di un unico piano d’isolamento al di sotto del quale viene effettuato il taglio dei pilastri e l’inserimento dei dispositivi di isolamento. Il lavoro riporta nel dettaglio la valutazione della vulnerabilità delle strutture esistenti, il progetto di adeguamento sismico e, infine, la valutazione della risposta sismica sotto terremoti di elevata intensità
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
