District-scale numerical analysis of settlements related to groundwater lowering in variable soil conditions
Full text linkThis study presents a novel framework in which numerical modelling contributes to the performance of district-scale, subsidence-induced damage assessment in cities where ground settlements affect entire quarters. Therein, the implementation of expeditious procedures offers geotechnical engineers the possibility of contributing beyond the typical site scale. For this purpose, several “typified” hydro-geomechanical-loading (HGL) models, which represent (simplified) scenarios of masonry buildings undergoing settlements, were set up to account for different predisposing or triggering factors (i.e., soil heterogeneity, loading conditions, and groundwater variations) of settlement occurrence in built-up areas. These models exploit multi-source, wide-area input datasets encompassing the hydro-mechanical properties of geomaterials, in situ investigations and measurements (e.g., groundwater levels in wells), and innovative remote sensing data (i.e., DInSAR techniques). With reference to a district in Rotterdam City (the Netherlands), which was built on “soft soils”, the numerical simulations of different scenarios (i) provide an overview of the comparative role of predisposing or triggering factors on settlement occurrence and (ii) allow assessments of the expected induced damage to masonry buildings over 30 years with the exploitation of fragility curves. Considering the widespread diffusion of such geohazards, the proposed approach could help prioritise (rather expensive) maintenance work to the built heritage within sustainable strategies for subsidence risk mitigation.Applied MechanicsGeo-engineerin
Istoria della Compagnia di Gesù. L'Asia
No full textCon la sua Istoria della Compagnia di Gesù, Daniello Bartoli ha scritto un’opera essenziale per la storia della Chiesa, un pionieristico saggio di antropologia, un proto- romanzo esotico, ed è stato un esempio della più elegante scrittura del Seicento. Chiuso nel suo studio presso la sede dei gesuiti, nella casa dei professi in piazza del Gesù, per più di vent’anni ha compulsato una gran quantità di fonti provenienti da tutti i luoghi del mondo dove la Compagnia aveva impiantato le sue missioni. Bartoli descrive città, architetture, fiumi, montagne, animali, popolazioni, tradizioni di ogni parte del globo senza avere mai messo il naso fuori dall’Italia, un po’ come, molti anni dopo, farà Salgari. Racconta scontri e guerre, matrimoni, miracoli di ogni tipo come un abile narratore, tanto è vero che alcuni critici letterari lo considerano alla stregua di un romanziere. La sua prosa è stata un modello molto ammirato da Leopardi e copiato da Manzoni (perfino l’incipit dei Promessi sposi – è stato rilevato – è ricalcato su una sua descrizione del Gange). In tempi più recenti è diventato l’idolo di uno scrittore votato agli ossimori come Manganelli, che infatti ne ha esaltato il «sorvegliatissimo furore verbale», la «prosa labirintica e limpida». L’edizione moderna dell’Asia era stata affrontata a più riprese già molti anni fa da studiosi del calibro di Ezio Raimondi, Bruno Basile, Josef Wicki, ma per varie vicende editoriali e umane non è mai giunta in porto. Ora è stata finalmente realizzata, con apparati nei quali si possono verificare i resoconti originari da cui Bartoli partiva, vedendo così come lo scrittore li rielaborava e che tipo di selezione faceva
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
