I "peli" della Gatta Cenerentola di De Simone e del Cunto de li cunti di Basile. Una parodia dell'illustre don Benedetto Croce
No full textNel corso del presente intervento si pone l\u27attenzione sul profondo e prolifico legame letterario che intercorre tra il drammaturgo novecentesco Roberto De Simone e lo scrittore seicentesco Giovanbattista Basile. In questo senso si evidenziano tre tappe salienti. De Simone debuttò nel 1976 al Festival dei due Mondi di Spoleto con un\u27opera intitolata La gatta cenerentola chiaramente inspirata alla favola di Basile, nel 1989 pubblicò la traduzione dall\u27antico napoletano in dialetto moderno della raccolta Il Pentamerone ovvero Lo cunto de li cunti trattenimento de piccerille (Napoli, ed. Il Mattino), mentre del 2002 è la doppia riscrittura, in dialetto e in italiano, del Cunto de li cunti di Basile (Torino, Einaudi). L\u27analisi, in particolar modo, di quest\u27ultima opera permette, inoltre, di sottolineare il forte intento parodico di De Simone nei confronti di Benedetto Croce. Nell\u27anno del cinquantesimo anniversario della morte del filosofo abruzzese, De Simone decide di inserire nella propria riscrittura del Cunto di Basile il personaggio Croce, condannandolo irriverentemente a "un peteggiare involontario, ereditato dall\u27aerofagia patita prima di morire"
Development of a High Precision LYSO Polarimeter forEDM Search at COSY Storage Ring
No full textThe baryogenesis is one of the greatest unanswered questions in contemporary physics. According to Sakarov’s conditions for baryogenesis, a process must have occurred early in universe’s life, that violated the fundamental CP-symmetry and led to the dominance of matter over antimatter in our universe. However all descriptions provided by the Standard Model in terms of CP-violating processes are insufficient by several order of magnitude to explain the observed abundance of matter. There must be some larger CP violation source, the observation of which could lead to the explanation of the matter-antimatter asymmetry and to new physics beyond the SM.
A strong source of CP violation could manifest in the existence of an Electric Dipole Moment (EDM) of elementary particles. For neutral particles EDMs investigations started about 60 years ago, the approach was based on the use of magnetic traps, so far all results of EDM measurements are compatible with a vanishing EDM value.
EDM searches on charged particles like protons and deuterons cannot be based on the same approach as for neutral particles, since the application of electric fields would result in an acceleration of the particle; therefore the use of storage rings in experiments aiming to directly measure a non-vanishing EDM on charged particles has been suggested by scientific collaborations all around the world.
The ideal scenario would be an EDM-search dedicated electric storage ring to be developed on purpose to perform an EDM measurement on proton. As a first step towards a dedicated storage ring, feasibility studies on deuteron beams are performed by the JEDI (Jülich Electric Dipole Investigations) collaboration at the magnetic storage ring COSY (Cooler Synchrotron) at Forschungszentrum Jülich in Germany.
The idea is based on the manipulation of the spin of the particles in the ring by use of a particular kind of radio frequency Wien Filter which acts on particles EDM leaving their orbit unperturbed, in such

a way to obtain a beam vertical polarization build-up which is proportional to the EDM value. The polarization-induced asymmetry in beam particles elastically scattered off a target, proportional to beam polarization, is then measured via a polarimeter and it is possible to obtain a value for the EDM.
The cycles of tests that led to the development of the prototype of such a high precision polarimetry detector, made of a number of LYSO scintillator crystal modules and with a readout system based only on Silicon Photomultipliers (SiPMs), is the topic of the present thesis.
In chapter I the theoretical background is presented. Chapter II is dedicated to a detailed description of the main principles in the use of storage rings for EDM searches in charged particles. Chapter III is a description of the COSY facility at FZ-Jülich and in chapter IV all the results from the tests performed in the development of the LYSO polarimeter are presented in detail.The baryogenesis is one of the greatest unanswered questions in contemporary physics.

Marketing Metrics in the Wine Retailing Industry
No full textOver the years, many companies integrated the Key Performance Indicators (KPIs) tools, into their reporting activities, leading to a deep transformation of the business models and marketing strategies. This study has dual aims: first, to recognize and validate the studies on Marketing Performance Measurement (MPM) in the wine retailing industry; second, to examine the relationships among the firm’s efforts to apply marketing metrics and some characteristics of the competitive environment. To reach these research aims, data on the overall 31 wineries were collected and analyzed in three different countries. The main research tool is the structured questionnaire that considers three different marketing metrics dimensions, that is transactional, attitudinal and web customer metrics. Subsequently, by a structural equation method (PLS-PM), it will be statistically estimated the weight of marketing metrics in the wine retailing industry
Visualization of scattering angular distributions with the SAP code
No full textSAP (Scattering Angular distribution Plot) is a graphical tool developed at the University of Bologna to compute and plot Rayleigh and Compton differential cross-sections (atomic and electronic), form-factors (FFs) and incoherent scattering functions (SFs) for single elements, compounds and mixture of compounds, for monochromatic excitation in the range of 1–1000 keV. The computation of FFs and SFs may be performed in two ways: (a) by interpolating Hubbell’s data from EPDL97 library and (b) by using semi-empirical formulas as described in the text. Two kinds of normalization permit to compare the plots of different magnitudes, by imposing a similar scale. The characteristics of the code SAP are illustrated with one example

A Note on Binary Strategy-Proof Social Choice Functions
No full textLet Φn be the set of the binary strategy-proof social choice functions referred to a group of n voters who are allowed to declare indifference between the alternatives. We provide a recursive way to obtain the set Φn+1 from the set Φn. Computing the cardinalities |Φn| presents difficulties as the computation of the Dedekind numbers. The latter give the analogous number of social choice functions when only strict preferences are admitted. A comparison is given for the known values. Based on our results, we present a graphical description of the binary strategy-proof social choice functions in the case of three voters
Coalitional economies with public projects
No full textWe prove that the welfare theorems hold in the framework of coalitional exchange economies with public projects, both in case of pure exchange and in the presence of production. The space of agents is assumed to be non-atomic (single traders are negligible) and infinitely many commodities are allowed to be present on the market
Proceedings of the LREC 2020 workshop on Resources and Techniques for User and Author Profiling in Abusive Language (ResT-UP 2020)
No full textThis volume documents the Proceedings of the 1st Workshop on Resources and Techniques for User and Author Profiling in Abusive Language (ResT-UP), held online on 12 May 2020 as part of the LREC 2020 conference (International Conference on Language Resources and Evaluation).
The workshop aimed at bringing together researchers and scholars working on author profiling and automatic detection of abusive language on the Web, e.g., cyberbullying or hate speech, with a twofold objective: improving the existing LRs, e.g., datasets, corpora, lexicons, and sharing ideas on stylometry techniques and features needed for profile information extraction and classification. ResT-UP targeted Profiling scholars and research groups, experts in Statistic and Stylistic Analysis of texts as well as computational linguists who investigate author profile and personality both in short texts (social media posts, blog texts and email) and in long texts (such as pamphlets, (fake) news and political documents). ReST-UP represented an opportunity to share profiling experiments with the scientific community and to show automatic detection techniques of abusive language on the Web. Despite the cancellation of LREC 2020 due to the COVID-19 international emergency, ResT-UP was organized online on Microsoft Teams on May 12th 2020 and the programme included three oral presentations and featured an invited talk by Paolo Rosso. ResT-UP was attended by about fifty representatives of academic and industrial organisations
Intelligenza artificiale e diritto penale: qualche aggiornamento e qualche nuova riflessione
No full textGiovan Battista Basile tra “favole” campanilistiche e realtà documentaria
No full textThis essay examines how the false belief that Giovan Battista Basile – the celebrated author of Lo Cunto de li Cunti – was born in Giugliano (Campania, Italy) on February 15, 1566, as the second son of Giovanni Giacomo Basile and Laudonia Milone arose and spread. “Cavalier” Basile actually died in Giugliano on February 23, 1632, from a virulent epidemic of diphtheria, after serving only a few days as feudal governor of Giugliano. Supported by a local priest as early as 1715, and later by local journalists, the erroneous thesis – based on a case of homonymy that actually debases the true identity of Basile’s birth parents – was however further revived in the 1970s-1980s by the media. This essay definitively refuses the false “Giugliano thesis” by gathering extremely detailed information from many different sources (Basile’s works, letters, and new unpublished documents). Through these researches, it can be definitively concluded that the famous writer Giovan Battista and the well-known singer Andreana, his sister, were born respectively in 1583 and 1586 in Naples to Francesco Antonio Basile and Cornelia Daniele and were both registered in the parish of Sant’Anna di Palazzo.Questo saggio esamina come sia nata e si sia diffusa la falsa credenza che Giovan Battista Basile - il celebre autore de Lo Cunto de li Cunti - sia nato a Giugliano (Campania, Italia) il 15 febbraio 1566, come secondogenito di Giovanni Giacomo Basile e Laudonia Milone. Il "Cavalier" Basile morì effettivamente a Giugliano il 23 febbraio 1632, a causa di una virulenta epidemia di difterite, dopo aver ricoperto per pochi giorni la carica di governatore feudale di Giugliano. Sostenuta da un sacerdote locale già nel 1715, e successivamente da giornalisti locali, la tesi errata - basata su un caso di omonimia che in effetti svilisce la vera identità dei genitori naturali di Basile - è stata però ulteriormente ripresa negli anni Settanta-Ottanta dai media. Questo saggio confuta definitivamente la falsa "tesi di Giugliano" raccogliendo informazioni estremamente dettagliate da diverse fonti (opere di Basile, lettere e nuovi documenti inediti). Attraverso queste ricerche, si può concludere definitivamente che il famoso scrittore Giovan Battista e la nota cantante Andreana, sua sorella, nacquero rispettivamente nel 1583 e nel 1586 a Napoli da Francesco Antonio Basile e Cornelia Daniele e furono entrambi registrati nella parrocchia di Sant'Anna di Palazzo
