Recognizing cultural concepts: Joyce, Woolf, Mann and Musil

The purpose of this thesis is to establish a direct relationship between literature and fields of knowledge such as science and technology, by focusing on some concepts that were fundamental for both science and the humanities at the beginning of the 20th century. The concepts are those of simultaneity, multiple points of view, map, relativity and acausality. In the spirit of several recent ideas, for example Katherine Hayles’ isomorphism notion, the dissertation shows how writers such as James Joyce, Virginia Woolf, Thomas Mann and Robert Musil developed the mentioned concepts within their narratives. The working hypothesis is that those concepts were at a crossroad of human activities, and that those authors used them extensively within their narratives. It is further argued that those same concepts – as developed by Joyce in Ulysses, Woolf’s shorts stories and novels from the end of the 1910’s until the end of the1920’s, Mann’s Der Zauberberg (The Magic Mountain), and Musil’s Der Mann ohne Eigenschaften (The Man Without Qualities) — are still fundamental for our conception of time and space today. The thesis is divided into two parts. The first two chapters will analyse the concepts of simultaneity and multiple points of view and their relationship to cartography as developed within English literature and culture. The next two chapters will address the concepts of relativity and acausality, as developed within German literature and culture.

Musculoskeletal tissue regeneration by human non-embryonic stem cells

The aim of this thesis was to investigate the regenerative potential of alternative sources of stem cells, derived from human dental pulp (hDPSCs) and amniotic fluid (hAFSCs) and, specifically, to evaluate their capability to be committed towards osteogenic and myogenic lineages, for the eventual applicability of these stem cells to translational strategies in regenerative medicine of bone and skeletal muscle tissues. The in vitro bone production by stem cells may represent a radical breakthrough in the treatment of pathologies and traumas characterized by critical bone mass defects, with no medical or surgical solution. Human DPSCs and AFSCs were seeded and pre-differentiated on different scaffolds to test their capability to subsequently reach the osteogenic differentiation in vivo, in order to recover critical size bone defects. Fibroin scaffold resulted to be the best scaffold promoting mature bone formation and defect correction when combined to both hDPSCs and hAFSCs. This study also described a culture condition that might allow human DPSCs to be used for human cell therapy in compliance with good manufacturing practices (GMPs): the use of human serum (HS) promoted the expansion and the osteogenic differentiation of hDPSCs in vitro and, furthermore, allowed pre-differentiated hDPSCs to regenerate critical size bone defects in vivo. This thesis also showed that hDPSCs and hAFSCs can be differentiated towards the myogenic lineage in vitro, either when co-cultured with murine myoblasts and when differentiated alone after DNA demethylation treatment. Interestingly, when injected into dystrophic muscles of SCID/mdx mice - animal model of Duchenne Muscular Dystrophy (DMD) - hDPSCs and hAFSCs pre-differentiated after demethylating treatment were able to regenerate the skeletal muscle tissue and, particularly, to restore dystrophin expression. These observations suggest that human DPSCs and AFSCs might be eventually applied to translational strategies, in order to enhance the repair of injured skeletal muscles in DMD patients.

1967-1987: l'altra civiltà del testo. Impulsi storici e scrittura nel teatro d'innovazione francese

Lo studio analizza le svolte nel teatro di innovazione francese prodotte dalla rivolta sociale e dalla sua rivoluzione culturale del 1968. La ricerca si è concentrata su tre livelli di analisi: un'analisi – storica, politica, sociale, culturale – dell'anno-tournant; un'analisi delle reazioni nel mondo del teatro contemporanee alla rivolta; un'analisi delle prassi spettacolari di lunga durata originate dall'evento. Sono stati, quindi, esaminati criticamente i testi cardine degli intellettuali ispiratori, protagonisti e interpreti della breccia culturale, per poi rintracciare i valori emersi all'interno del mondo dello spettacolo. La contestazione sociale ha agito sul mondo del teatro producendo delle ripercussioni immediate – l'occupazione dell'Odéon, la contestazione al XXII Festival d'Avignon, la produzione della Déclaration de Villeurbanne – e delle prassi di lunga durata che hanno agito sui processi formativi e creativi delle compagnie francesi che, dalla fine degli anni Sessanta, hanno prodotto creazioni collettive (in particolare il Théâtre du Soleil e il Théâtre de l'Aquarium, ma anche la Nouvelle Compagnie d'Avignon, il Grand Magic Circus e il Théâtre Populaire di Lorraine) e sul corpus drammaturgico e teorico di Michel Vinaver. Sono state, quindi, analizzate le relazioni che si sono instaurate tra i protagonisti appena nominati e i differenziati contesti, sociali e teatrali, facendo emergere nuove istanze creative. Tali istanze hanno saputo rispondere alle spinte etiche ed estetiche del momento storico, le hanno declinate sul piano delle prassi teatrali e rilanciate verso modalità nuove che hanno favorito l'emersione di una nuova civiltà del testuale.
