L. Palumbo, A proposito di Mauro Bonazzi, Processo a Socrate
No full textThe fine book of Mauro Bonazzi looks into the causes which brought about the death sentence of Socrates in 5th century BC Athens. One of these causes is to be found in the similarity of thought and behaviour between Socrates and the sophists. Such a similarity, evident in Aristophanes’ works, is denied in Plato’s dialogues, but it is exactly in those dialogues, if one delves into them deeply enough, that it is possible to find out all the reasons why Socrates was sentenced to death
«Beltate» e «amore» nella Vita nova: i princìpi della teologia poetica di Dante
No full text«Beltate» and «amore» in the Vita nova:
the principles of Dante’s poetic theology. - A critical analysis of theoretical issues in the text of Vita nova – the young Dante’s first major work and the greatest expression of the genre of courtly love – demonstrates a very impressive utilisation of theologically oriented terminology and themes, coming from scriptural allusions and the exegetical patterns of the early mediaeval monastic literature (especially from the twelfth century). Such a new perspective suggests the possibility of appreciating the «libello» as a witness to a systematic speculative framework, and the author as a bearer of an already defined anthropological and theological vision, which will find its definitive realisation in his subsequent works, from the Convivio to the Commedia. In particular, the analysis of the idea of gentilezza — the disposition of the loving soul to find in the beloved’s beauty (bellezza) the evidence of her virtues — reveals the ultimate goal of the poet’s theoretical-ethical mission: he employs theological poetry as a valuable instrument, useful for showing mankind the way to the happiness that is only realizable through complete service to the truthful Principle of Love (amore)
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
Radiation Damping and Quantum Excitation for Longitudinal Charged Particle Dynamics in the Thermal Wave Model
No full textOn the basis of the recently proposed thermal wave model (TWM) for particle beams, we give a description of the longitudinal charge particle dynamics in circular accelerating machines by taking into account both radiation damping and quantum excitation (stochastic effect), in the presence of a RF potential well. The longitudinal dynamics is governed by a 1-D Schrodinger-like equation for a complex wave function whose squared modulus gives the longitudinal bunch density profile. In this framework, the appropriate r.m.s. emittance scaling law, due to the damping effect, is naturally recovered, and the asymptotic equilibrium condition for the bunch length, due to the competition between quantum excitation (QE) and radiation damping (RD), is found. This result opens the possibility to apply the TWM, already tested for protons, to electrons, for which QE and RD are very important
"'Poeta omnes pulchritudines quaeret': osservazioni sul bello in Girolamo Fracastoro"
No full textL’indagine sulla natura del “bello” viene condotta da Girolamo Fracastoro nel dialogo 'Naugerius', dedicato alla poetica. L’analisi si svolge su due percorsi: quello della poetica aristotelica da un lato, che pone la poesia, tanto nei mezzi quanto nei fini, come genere autonomo e dotato di peculiarità in virtù delle quali si distingue dai domini del 'verum' e del 'bonum'; dall'altro, viene rievocata l’idealità platonica del “bello”, autentico fattore ispiratore del poeta. Fracastoro approda così ad una sintesi che non è banale operazione sincretistica tra le principali tradizioni poetiche vive nell'Umanesimo, dedicando altresì uno spazio alle questioni concernenti i rapporti tra 'pulchrum' e 'verum'
