MatematicArte: la lezione di Galileo Galilei sulla struttura dell’Inferno di Dante MatematicArte: the lesson of Galileo Galilei on structure of Dante’s Inferno
No full textHow big is the Hell? How tall is Lucifer? To answer these questions, Antonio Manetti did the calculations and Galileo validated them. Would the students of the Accademia delle Belle Arti di Brera be able to describe this geometry? Many artists painted scenes about Hell’s episodes, more focusing on the feelings and passions the Hell is steeped in than referring to its geometry. This exhibition is a collaborative work between Paola Magnaghi and Tullia Norando (FDS - Dipartimento di Matematica del Politecnico di Milano) and Alessandra Angelini, artist and professor (Accademia delle Belle Arti di Brera), who presents a group of her students of Graphic, aimed to contribute to the contamination of scientific thoughts and artistic insights. The work is divided into two parts: the first dedicated to mathematical foundations and the second devoted to artistic interpretation. The topics of mathematical lessons are the themes of the opening video. Intrigued by the relationships between geometric design and artistic concept, the students made scale drawings of the Divina Commedia’s Hell, by using both several paper frames types and different art techniques. Later they produced original art works by personal interpretation and unrelated to the scientific explanation. The results reflect various artistic and creative sensibilities: drawings, paintings, engravings. The artistic workshop, conducted by A. Angelini, invites the public to participate by creating own fantasy drawings given a Hell’s framework, as a sort of dream boxes. The drawings can be exhibited as well in the room
Dialecticae Praestantia et Divisio. Achille Bocchi ad Antonio Bernardi, Illustrissimo filosofo

Il contributo di A. Angelini affronta la logica di Bernardi e il tentativo di emancipare l'analitica aristotelica dall'ontologia
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

No full textDispelling 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
