Le Confabulationes di Poggio e il «palcoscenico» della Curia
No full textIl saggio prende in esame la struttura e l’organizzazione retorica del Liber facetiarum di Poggio Bracciolini, avanzando alcune ipotesi sul progetto narrativo dell’autore alla luce delle modifiche apportate nelle diverse fasi redazionali del libro. L’accento viene posto sulla costruzione di una cornice dialogica, che coordina le singole pièce narrative e riconduce l’atto del narrare alle conversazioni del circolo umanistico della Curia pontificia. Da un lato, Poggio recupera il modello della «lieta brigata» del Decameron, adattandolo al nuovo contesto della "confabulatio" umanistica; dall’altro, approfondisce la dimensione comica e scenica dello scambio verbale, istituendo uno stretto rapporto fra modalità di recitazione e contenuto dei microtesti. In quest’ottica, le Confabulationes – così l’autore definisce il proprio libro – si incaricano di riprodurre e codificare la nuova prassi della convivialità cortigiana, aprendo la strada alle successive riflessioni teoriche di Pontano e di Castiglione.The article reviews the structure as well as the rhetorical organization of Poggio Bracciolini’s Liber facetiarum. Furthermore, it suggests some hypothesis on the author’s narrative project by examining the amendments to the book occurred over the different editing stages. The article focuses on the dialogical setting, which coordinates the narrative pieces and brings the act of narration back to the conversations held within the humanistic circle of the papal Curia. Poggio chooses the pattern of Decameron «lieta brigata» and adapts it to the new context of the humanistic "confabulatio"; he also emphasizes the comic and the theatrical aspects of verbal interaction and creates a close relationship between the way of acting and the content of microtexts. In this way, the Confabulationes – according to the title chosen by the author for his book – represent and encode the new practice of the courtesan conversation, which will lead to the theoretical treatises of Pontano and Castiglione
«Alcesti non è più Alcesti». La tragedia secondo Alberto Savinio
No full textA partire dai suoi precursori ottocenteschi, la cultura moderna ha elaborato una visione in negati- vo del tragico, insistendo sul tema della ‘morte della tragedia’ e dell’inattualità del genere tragico. La visione problematica e relativistica del mondo, che caratterizza larga parte delle esperienze no- vecentesche, nega infatti le ragioni del conflitto fra uomo e dio, fra uomo e cosmo, ed erode nel profondo le fondamenta gnoseologiche, etiche ed estetiche su cui si fondava il dramma classico. In questo contesto, le tragedie di Alberto Savinio, scritte nell’immediato secondo dopoguerra, offro- no un punto di osservazione estremamente interessante, proprio perché tematizzano all’interno del testo il problema della rappresentazione del tragico in un’epoca che, a dispetto delle guerre e del sangue versato, egli giudica assolutamente «indrammatica». L’articolo si propone di mettere a fuoco l’originale concezione che Savinio ha della tragedia – come superamento del tragico e del- l’angoscia moderna – analizzando in particolare l’Alcesti di Samuele, il dramma più complesso e am- bizioso cui l’autore affida il compito di veicolare la propria visione estetica, etica e politica.Since its nineteenth-century precursors, modern culture has produced a negative view of the trag- ic, focusing on the theme of the ‘death of tragedy’ and the irrelevance of the tragic genre. The rel- ativistic view of the world, which characterizes a large part of the twentieth century experience, in fact denies the reasons for the conflict between man and God, between man and the cosmos, and undermines epistemological, ethical and aesthetic foundations of the classic drama. In this context, the tragedies of Alberto Savino, written after World War II, offer a very interesting point of view because they reflect, within the text, upon the problem of representation of the tragic in an age that, in spite of wars and of the bloodshed, he considers absolutely «indrammatica». The ar- ticle intends to focus on Savinio’s original conception of the tragedy – as overcoming the tragic and the modern anguish – with particular regard to Alcesti di Samuele, the most complex and ambitious drama with which the author would communicate his aesthetics, ethics and politics vision
Organic field-effect based sensors for body parameters monitoring
No full textIn this paper we propose totally flexible organic field effect transistors (OFETs) assembled on plastic films as sensors for physiological parameters monitoring. In the first part, mechanical sensors for pressure and bending detection are presented and some biomedical sensing applications are illustrated. A sharp and reversible sensitivity of the output current of the device to an elastic deformation induced by means of a mechanical stimulus on the device channel is observed. In the second part, the possibility of using similar devices for bio- and chemo-detection is described. By exploiting the properties of the basic structure, the device can be combined with any kind of substrate to detect for instance the 3D bending of a flexible surface and/or for detecting pH of sweat. Robot skin and wearable electronics seem to be promising applications for this emerging technology
Anatomy of the glossopharyngeal nerve
No full textThe glossopharyngeal nerve is a lower cranial nerve arising in the posterior cranial fossa. Although this nerve has multiple branches and functional components, it is often overlooked clinically. This ninth cranial nerve has a close relation to the vagus nerve both structurally and functionally. Although the glossopharyngeal nerve is primarily a sensory nerve, it also carries autonomic and somatic motor fibers. This chapter will review the detailed anatomy of the glossopharyngeal nerve.</p
Abdominal pre- and para-aortic and inferior hypogastric plexuses
No full textThe abdominopelvic autonomic nervous system is a complicated network of interdigitated fibers stemming from the sympathetic and parasympathetic systems. Harmony between these two systems is important in the functions of the abdominopelvic viscera. This chapter highlights the specific course and origin of the fibers that come together to innervate the visceral structures of this region.</p
