The Alchemical Order of the World. Natural Causes and Divine Intervention in the Preziosa Nargarita Novella of Pietro Bono da Ferrara
Get PDFSince its origins, alchemy has had to deal with the problem of order. His eccentricity compared to other medieval knowledge posed questions about his collocation and the nature of the object he was looking for, the philosopher’s stone. This article presents the attempt, made by the doctor Pietro Bono da Ferrara, to embed alchemy in the school scientific system. In his work, the Pretiosa Margarita Novella, he uses syllogism to order the treatment of alchemy, the subalternatio to place it within the system of sciences and the concept of forma specifica to describe the philosopher’s stone and insert it in metals’ generation process. In this way, Bono conceives alchemy as a science referring to two orders, the natural one of metal generation, in which it operates, and the divine one, to which he must appeal to find the philosopher’s stone, which are complementary to each other since they both have their origin in God.Fin dalle sue origini l’alchimia ha dovuto confrontarsi con il problema dell’ordine. La sua eccentricità rispetto agli altri saperi medievali poneva questioni sulla sua collocazione e sulla natura dell’oggetto che cercava, la pietra filosofale. L’articolo presenta il tentativo fatto dal medico Pietro Bono da Ferrara di riordinare la materia alchemica e di incasellarla nel sistema scientifico scolastico. Nella sua opera, la Pretiosa Margarita Novella, egli utilizza il sillogismo per ordinare la trattazione dell’alchimia, la subalternatio per definirla come una tra le scienze naturali e collocarla all’interno del sistema dei saperi e il concetto di forma specifica per descrivere la pietra filosofale e inserirla nel processo di generazione dei metalli. In questo modo Bono concepisce l’alchimia come una scienza che risponde a due ordini, quello naturale di generazione dei metalli, nel quale opera, e quello divino, al quale deve fare appello per trovare la pietra, che sono complementari tra loro, poiché hanno la loro origine in Dio.

Pietro d'Abano e Pietro Bono: due medici in difesa di astrologia e alchimia
Get PDFL’obiettivo di questa tesi è comprendere quale ambiente culturale abbia permesso la produzione della Pretiosa Margarita Novella di Pietro Bono da Ferrara, medico del XIV secolo. Si tratta di lunga e approfondita quaestio sulla liceità e scientificità dell’alchimia, scritta tra il 1323 e il 1330. Nel corso della tesi si prenderà in esame soprattutto l’università di Padova e si confronterà Pietro Bono con uni dei principali rappresentanti dello studium patavino nel corso dei primi decenni del XIV secolo, Pietro d'Abano, medico e autore di libri in difesa dell’utilizzo lecito dell’astrologia. Si inserirà Bono in questo contesto e lo si valuterà come espressione di un preciso momento storico e culturale, nel quale la riflessione scientifica sui saperi aveva raggiunto una raffinatezza tale, da poter interessare anche discipline come quella alchemica, solitamente esclusa dall’enciclopedia delle scienze. Si suddividerà dunque il lavoro in quattro capitoli: il primo analizzerà le conoscenze che possediamo su Bono, gli insegnamenti delle università di Padova e di Bologna, le biografie e le opere dei medici che operarono in queste città; il secondo si concentrerà sui testi al centro del confronto tra Pietro d'Abano e Pietro Bono e sulle fonti e le metodologie comuni; il terzo si soffermerà sul confronto tra le dottrine alchemiche e astrologiche comuni all’interno dei testi; il quarto esaminerà i concetti alla base della fondazione epistemologica delle discipline che i due autori difendono

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
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
