LA SFIDA CONTEMPORANEA DELLA TRADIZIONE COSTRUTTIVA: RICOSTRUIRE LO SPAZIO. SISTEMI VOLTATI IN PIETRA REALIZZATI IN CANTIERE E NEI LABORATORI DIDATTICI UNIVERSITARI
No full textNel cantiere di recupero e/o restauro, così come nelle versatili accezioni della ricerca
universitaria sui temi della costruzione storica, non è infrequente imbattersi negli studi
stereotomici sull’analisi e la riproposizione di sistemi voltati, talora originali – per alcuni
versi anche complessi - per geometria costitutiva, apparecchiatura, opere di carpenteria
preliminare/sussidiaria. Le intuizioni del progettista originario, la codifica della
regola dell’arte desunte dalla trattatistica di genere diventano elementi fondamentali
per il cosiddetto “cantiere della conoscenza”, fase preliminare propedeutica qualora
si debba intervenire nella riproposizione di questi sistemi voltati poiché scomparsi
a seguito di crolli, incolte demolizioni o stravolgimenti della fabbrica primigenia.
Ne derivano veri e propri capitoli di “architettura tecnica” desunti dai documenti di
cantiere coevi, dalla lettura in situ degli edifici che si studiano o su cui si interviene,
per i quali la storia della costruzione non rimane una lingua morta ma contemporanea,
la sola utile a suggerire le linee guida che indirizzano poi la ricostruzione filologica, a
dettare il passo delle procedure da seguire nella conoscenza del materiale lapideo da
utilizzare, il taglio della pietra, i modi di realizzare l’apparecchio, eventuali presidi da
introdurre per il miglioramento tecnologico-strutturale, oltre che per l’attenuazione
della vulnerabilità sismica. Lo studio della genesi stereotomica e della successiva
fase esecutiva – spesso legata alla perizia artigianale di intere categorie di maestranze
specializzate – può risultare una chiave di studio applicato non solo cantieristico,
ma anche didattico con la proposizione - nelle scuole di Ingegneria ed Architettura
- di workshops/laboratori specifici che insegnano fin da subito agli studenti/futuri
progettisti – un “saper fare” facilmente spendibile nelle ricadute professionali.
Questo studio descrive casi studio, esperienze di cantieri di restauro e di recupero
siciliano nonché raccontare il “Laboratorio di stereotomia” effettuato sia nel 2016
che quest’anno per i corsi della classe LM4 presso il Dipartimento di Architettura
(D’ARCH) dell’Università di Palermo.During recovery and/or inside restoration sites, as well as in the multiple and versatile
meanings of researches about construction history, it’s not infrequent to chance upon
stereotomy studies related to the analysis and revival of stony vaulted systems, sometimes
original for constitutive geometry, masonry typology, preliminary carpentry works. The
intuitions of the original designer, the codification of the “rule of art” deduced from
specific treatises, become fundamental elements for the so-called “knowledge building
yard”, a preparatory phase when we have to intervene rebuilding these vaulted systems
since they disappeared as a result of collapses, uncultivated demolitions or twisting of
original buildings. The result is that to have really available some chapters of “technical
architecture” taken from contemporary archival-construction documents, from the on
site interpretation of studying buildings, for which construction history does not remain
a dead language but also today a contemporary way to intervene, the only one useful
to suggest the guidelines that direct a philological reconstruction, able also to dictate
the stony materials to be used, the cutting ways of stone, the techniques of realizing the
vaulting systems, finally even the possible measures to be introduced for technologicalstructural
improvement, as well as for the attenuation of seismic vulnerability. The study
of the first stereotomy genesis and the executive phase - often linked to the artisanal
expertise of entire categories of specialized workers - can turn out to be a key applied not
only to building yard but also to university teaching with the proposition - in the Degree
Courses of Engineering and Architecture - of specific practical workshops/laboratories
that develop the students/future designers a “know-how” that can be easily spent on
professional benefits. This study aims to describe study cases and applied researches, also
experiences taken directly from Sicilian restoration and recovery building yards as well
as telling the didactic experience of “stereotomy workshop” carried out both in 2016 and
this year inside the degree courses (LM4) at the Department of Architecture in Palermo
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

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
