    Bow-Tie Structures of Twitter Discursive Communities

    No full text
    In the analysis of Twitter debate, the recent literature focused on discursive communities, i.e. clusters of accounts interacting among themselves via retweets. In the present work, we studied discursive communities in 8 different thematic Twitter datasets in various languages. Surprisingly, we observed that almost all discursive communities therein display a bow-tie structure during political or societal debates. Instead, they are absent when the argument of the discussion is different as sport events, as in the case of Euro2020 Turkish and Italian datasets. We furthermore analysed the quality of the content created in the various sectors of the different discursive communities, using the domain annotation from the fact-checking website Newsguard: we observe that, when the discursive community is affected by m/disinformation, the content with the lowest quality is the ones produced and shared in SCC and, in particular, a strong incidence of low- or non-reputable messages is present in the flow of retweets between the SCC and the OUT sectors. In this sense, in discursive communities affected by m/disinformation, the greatest part of the accounts has access to a great variety of contents, but whose quality is, in general, quite low; such a situation perfectly describes the phenomenon of infodemic, i.e. the access to "an excessive amount of information about a problem, which makes it difficult to identify a solution", according to WHO).Comment: 47 pages, 25 figures, 7 table

    Pairs of foliations and Mattei-Moussu's Theorem

    No full text
    International audienceWe prove a reduction of singularities for pairs of foliations by blowing-up, and then investigate the analytic classification of the reduced models. Those reduced pairs of regular foliations are well understood. The case of a regular and a singular foliation is dealt with Mattei-Moussu's Theorem for which we provide a new proof, avoiding Gronwall's inequality. We end-up announcing results recently obtained by the first author in the case of a pair of reduced foliations sharing the same separatrices

    No full text
    L'autore analizza la rivista "Il Gatto Selvatico" (rivista aziendale diretta per dieci anni dal poeta Attilio Bertolucci) che faceva parte degli strumenti di comunicazione dell'Eni di Enrico Mattei. L'autore descrive la nascita della rivista e la sua struttura, poi spiega la funzione sociale della rivista per i lettori, in particolare per i dipendenti aziendali. Oltre a illustrare le attività aziendali e del Presidente, lo scopo della rivista era di rafforzare il senso di appartenenza alla «grande famiglia Eni». Nel complesso degli strumenti di propaganda utilizzati dall'Eni (pubblicità sulla stampa, in televisione e nei film documentari), l'autore sostiene che «Il Gatto Selvatico» ha dato il suo contributo al consolidamento del potere personale di Mattei contro avversari politici e del mondo economico.The author analyses the magazine «Il Gatto Selvatico» (corporate house organ directed for ten years by the poet Attilio Bertolucci) who was part of the instruments used in to communications strategies in Enrico Mattei’s Eni (Ente nazionale idrocarburi). The author describes the birth of the magazine and its structure, then he explains the social function of the magazine for readers, especially for corporate employees. As well as illustrate the activities of Eni and his President, the purpose of the magazine is to strengthen the sense of belonging to the «big Eni family», mentioned Mattei.

    py2DIC. A New Free and Open Source Software for Displacement and Strain Measurements in the Field of Experimental Mechanics

    No full text
    Thanks to the advances in computer power, memory storage and the availability of low-cost and high resolution digital cameras, Digital Image Correlation (DIC) is currently one of the most used optical and non-contact techniques for measuring material deformations. A free and open source 2D DIC software, named py2DIC, was developed at the Geodesy and Geomatics Division of the Sapienza University of Rome. Implemented in Python, the software is based on the template matching method and computes the 2D displacements and strains of samples subjected to mechanical loading. In this work, the potentialities of py2DIC were evaluated by processing two different sets of experimental data and comparing the results with other three well known DIC software packages Ncorr, Vic-2D and DICe. Moreover, an accuracy assessment was performed comparing the results with the values independently measured by a strain gauge fixed on one of the samples. The results demonstrate the possibility of successfully characterizing the deformation mechanism of the investigated materials, highlighting the pros and cons of each software package

    L’invenzione dell’antico alla corte dei Gonzaga. Lelio Manfredi e la descrizione della villa di Lucullo in Tusculum

    No full text
    This paper focuses on the treatise Pallazzo di Lucullo, written in ca. 1515 by the humanist Lelio Manfredi, which reconstructs the villa in Frascati (ancient Tusculum) built for the Roman aristocrat Lucullus. The vernacular manuscript, dedicated to Isabella d’Este Gonzaga, Marchioness of Mantua, and preserved in the Biblioteca Marciana in Venice, testifies to Manfredi’s antiquarian interests. First of all, the essay investigates the ancient and modern sources used by the author, dedicating particular attention to Varro’s description of his own villa of Cassino, which served as Manfredi’s model for the reconstruction of the Lucullian villa. The Pallazzo di Lucullo is then framed within the context of architectural treatises written by men of letters in the sixteenth century – such as Alvise Cornaro and Giangiorgio Trissino – and of the humanistic reception of the aviary, also admired by Erasmus and Giulio Giovio. Finally, the paper discusses the Pallazzo di Lucullo within the cultural context of the Gonzaga dukedom, where Manfredi lived for several years. By describing the ancient villa, the author presents himself as an artistic adviser of the Gonzaga, who were renowned patrons thanks to their important architectural commissions. Thus, the analysis of the Pallazzo di Lucullo sheds new light on the dynamics at this Renaissance court, promoting the study of the intermediaries who introduced the Gonzaga to antiquarianism and ancient architecture

    Personality traits and physical activity may be involved in colorectal carcinogenesis: preliminary data from a cross-sectional study on patients undergoing colonoscopy

    No full text
    The preliminary results of a study aiming at assessing potential risk factors for carcinogenesis, including metabolic and inflammatory parameters, life-style, psychosocial and personality traits, according to a holistic approach are here reported and briefly described. The presence of at least one adenoma was significantly associated to the TCI Self Transcendence (ST) domain (OR=1.36, p=0.04) and to the absence of regular physical activity (OR=0.14, P=0.03), that may suggest pathways to definition of high risk for metabolic syndrome and carcinogenesis
