La Valleriana: dall’architettura al territorio, la formazione di un paesaggio
No full textNel 2007, sulla base dell’esperienza maturata sulla città di Pescia – di cui era stato studiato l’impianto urbano ed analizzate alcune delle principali fabbriche – si è costituito in ambito accademico un gruppo di ricerca, pluridisciplinare fin dall’origine, con lo scopo di documentare le fasi di formazione e trasformazione dei dieci insediamenti altomedievali presenti alle spalle del comune-capoluogo ed appartenenti al peculiare ‘organismo territoriale’ della Valleriana, ai più nota come ‘Svizzera Pesciatina’.
L’ambizioso progetto ha trovato appoggio, oltre che nelle istituzioni locali (in primo luogo nel Comune di Pescia) anche nelle numerose associazioni presenti sul territorio e nelle fondazioni bancarie della provincia di Pistoia, senza il cui apporto di carattere finanziario la ricerca stessa non avrebbe potuto essere realizzata nei tempi e nei modi con cui è stata condotta fino ad oggi.
Lo specifico ambito scientifico di quello che può essere definito come il ‘nucleo’ del gruppo di lavoro, legato alle discipline del rilievo e della rappresentazione dell’architettura e dell’ambiente, ha fatto sì che la base imprescindibile della ricerca fosse il rilevamento accurato degli insediamenti realizzato attraverso le tecniche digitali oggi a disposizione, che consentono una rapidità di presa del dato impensabile solo fino a due decenni fa.
La comprensione dei fenomeni evolutivi di ciascuna delle tre ‘castella’ ad oggi esaminate ha comportato l’analisi dei fatti scalarmente più grandi (le dinamiche territoriali legate ai fenomeni di antropizzazione di una determinata area dalla specifica storia geologica e con una propria identità orografica ed idrografica) e di quelli più piccoli (inerenti i tessuti edilizi e le architetture che ne fanno parte) in un continuo rimando tra l’uno e l’altro che non presenta soluzioni di continuità né per ciò che riguarda lo spazio, né per ciò che concerne il tempo. Ed in tal senso è proprio nelle vicende storiche, quelle legate alla storia universale e quelle inerenti gli avvenimenti locali, che sono state ricercate le ragioni delle trasformazioni stesse dei centri demici.
Il rilievo degli elementi fisici dei centri fortificati ha consentito di documentare i segni che la storia ha impresso nelle loro murature; segni che sono stati decodificati facendo ricorso all’archeologia dell’architettura, sulla base delle conoscenze che si hanno sulle tecniche murarie utilizzate in un dato momento storico, sull’organizzazione del cantiere che ha eretto tali murature, sulla maestranze che vi prendevano parte e sulla facilità di reperimento della materia prima, consentendo così di delineare una storia delle ‘evidenze materiali’ dell’edificato. Al suo fianco la storia dell’architettura e quella dell’arte hanno dato il loro fondamentale contributo nel riconoscimento di stilemi formali che consentono di ascrivere un’opera ad un determinato personaggio o scuola, definendo degli ulteriori marcatori temporali
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Rischio di lutto complicato in familiari di pazienti oncologici in fase terminale: uno studio di screening
No full textThe purpose of this study is to evaluate the risk of complicated bereavement in relatives of terminally ill patients, admitted to the hospice, in order to plan psychological interventions. The assessment tool used was the Parkes and Weiss’s “Bereavement Risk Index”. The sample consisted of 215 family members and showed high risk in 113, medium risk in 57 and low risk in 45. The study showed a statistically significant difference related to gender and role (caregiver/not caregiver) in emotional reactions, self evaluation of risk and personal resources, and request of psychological help. Eighty-five out of 113 relatives with high risk score accessed to only one psychological interview avoiding further support
Defective mRNA levels are responsible for a beta-thalassemia phenotype associated with Hb Federico II, a novel haemoglobin variant (beta 106 (G8) Leu->Val).
No full textThis study provides the first experimental evidence that a single nucleotide mutation within the coding region of the β-globin gene affects mRNA expression levels and causes a β-thalassemic defect. Furthermore, our data suggest that other regions besides the 3′UTR, whose role in constitutively regulation of this mechanism has been recently identified, may contribute to the stabilization of β-globin mRNA and could, therefore, help to characterize the molecular basis of thalassemic hemoglobinopathies
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
