Roland Barthes, le zone grige e l'utopia - Roland Barthes, grey areas and utopia
No full textL’articolo fa riferimento a un preciso gruppo di testi (Il grado zero della scrittura, Miti d’oggi, Critica e verità, Lezione, Il brusio della lingua, Barthes di Roland Barthes), traendo spunto dall’interesse che Barthes vi dimostra nei confronti di specifici cortocircuiti del discorso e del pensiero, qui definiti zone grige, per poi proiettarlo entro la sua riflessione sull’utopia e sulla letteratura. In un primo momento l’articolo insiste sulla correlazione profonda tra la critica dell’ideologia e la semiologia barthesiane allo scopo di isolare due importanti nuclei tematici: il rapporto tra potere e linguaggio e la questione dell’ambiguità della scrittura. Successivamente, il discorso viene contestualizzato entro l’indagine barthesiana sul rapporto tra utopia e letteratura, individuandone alcune forme e figure specifiche, e sul problema della referenzialità.
The essay is based on a specific group of books (Writing Degree Zero, Mythologies, Criticism and Truth, Inaugural Lection, Collège de France, The Rustle of Language, Roland Barthes by Roland Barthes) and draws inspiration from the strong interest that Barthes dedicates to some particular phenomena, here defined as grey areas, which are equal to a sort of ʽshort-cutʼ in verbal expression and in the articulation of thoughts; then relates it to his reflection on literature and utopia. At first, the essay emphasizes the connection between Barthes’ semiotics and critique of ideology, in order to identify two important topics: the relation between power and language and writing’s resolute ambiguity. Subsequently, these themes are related to Barthes’ reflection on the connection between literature and utopia, identifying some of its forms and figures, and on the problem of literature and referentiality
Il senso dell’autore, i sensi dell’opera: alcune riflessioni di Roland Barthes e Hans-Georg Gadamer sulla lettura
No full textLeggendo le pagine dedicate da Barthes e Gadamer al fenomeno dell’interpretazione del testo letterario, si nota la loro comune presa di posizione nei confronti della piena identificazione del senso dell’opera con quello voluto ed espresso dall’autore. Sulla base di questa comunanza prospettica, l’articolo punta a ricostruire l’orizzonte di fondo su cui l’uno e l’altro concepiscono rispettivamente il fenomeno dell’interpretazione e, di conseguenza, a discutere dei casi di convergenza delle loro proposte, a partire dalla rivendicazione della pluralità dei sensi e delle interpretazioni dell’opera e, correlativamente, dalla valorizzazione della lettura.Reflecting on the phenomenon of literary interpretation, both Barthes and Gadamer refused the consideration of the sense expressed by the author as the only sense of the text. On this basis, the article aims to identify the framework according to which they respectively reflect on literary interpretation and therefore to discuss about the convergences implied by their propositions, with particular regard to the acknowledgement of the various senses and interpretations of the literary text and to the consequent valorization of reading

Abstract
SiC/SiC ceramic matrix composites (SiCf/SiC CMCs) are regarded as the new materials for the hot-section components of aircraft gas turbine engines, since they have one-third of the density of metallic superalloys, a higher temperature capability, good mechanical strength, and excellent thermal shock resistance. However, high-temperature water-vapor-rich combustion gases can induce severe surface recession phenomena in SiC/SiC leading to component failure. For this reason, it is necessary to design protective coatings, i.e., environmental barrier coatings (EBCs), able to protect the SiC/SiC surface in combustion environments. In the present work, ytterbium monosilicate (Yb2SiO5), stable when exposed to water vapor at high temperatures, and ytterbium disilicate (Yb2Si2O7), characterized by a thermal expansion coefficient closer to that of the substrate, were selected for a multilayer EBC system. EBCs were processed using the atmospheric plasma spray (APS) technique. A set of deposition parameters were tested, varying the power of the torch, and the composition and microstructure of the deposited coatings were studied in terms of porosity, crack density, and post-deposition phase retention by performing SEM, EDS, and XRD analysis. The results allow for the definition of the influence of deposition parameters on the final properties of multilayer EBC coatings

Scrivere senza anestesia. La chiarezza di Giulia Niccolai
No full textIl saggio colloca storicamente la narratrice e poetessa Giulia Niccolai nel canone del Novecento letterario italiano discutendone poetica e cifre stilistiche. L'ampia analisi proposta tocca tutte le opere dell'autrice evidenziandone i legami intertestuali, anche tra poesia e narrativa, e i progressivi sviluppi in un arco cronologico esteso, tra anni Sessanta e primi anni Duemila. Lo studio coglie anche l'importanza dei riferimenti alle arti visive, in particolare alla fotografia, che Giulia Niccolai ha praticato in prima persona negli anni della Neoavanguardia, e alla pittura americana.The essay places the narrator and poet Giulia Niccolai in the canonical twentieth century Italian literary discussing her poetics and stylistic figures. The wide analysis proposed touches all the works of the author highlighting the intertextual links, also between poetry and narrative, and the progressive developments in an extended chronological period, between the Sixties and early Twenties. The study also captures the importance of references to the visual arts, especially photography, which Giulia Niccolai has practiced in the years of the Neo-avant-garde, and to American painting

L'afrofuturismo tra Stati Uniti e Italia. Dalla memoria storica ai viaggi intergalattici per re-immaginare futuri postumani
No full textIn this article the author explores the cultural movement called Afrofuturism, tracing its origins, features, simbology, and its historical and political meanings. Starting from the (supposed) discoursive gap between African and African American people on one side and technology and science fiction on the other, this paradigm addresses themes related to the intersection of African Diaspora and African cultures with technology and science fiction, with the aim to recover the history of slavery and racism through the projections into alternative space-time contexts. In particular, the author explores the feminist afrofuturism perspective in order to examine the specific oppression and cultural production of African and African American women. In doing so, the author analyzes the development of afrofuturism in Italy, focusing on the work of the singer and beatmaker Karima 2G
BDC-Decomposition for global influence analysis
No full textIn biochemical networks, the steady-state input-output influence is the sign of the output steady-state variation due to a persistent positive input perturbation; if the sign does not depend on the value of the strictly positive system parameters, the influence is structural. As recently shown for small perturbations, when the linearized system approximation is valid, steady-state input-output influences can be structurally assessed, for biochemical networks with m unknown parameters, by means of a vertex algorithm with complexity 2m. This letter shows that the structural input-output influence of a biochemical network is a global property, which does not require any small-perturbation assumption. It also shows that, using a new algorithm, the complexity can be reduced down to 2m-n , where n is the system order, thus drastically reducing the computation time. Finally, when the uncertain parameters belong to known intervals, non-conservative bounds are given for the steady-state ratio between output and input, allowing for sensitivity analysis.Accepted Author ManuscriptTeam Tamas Keviczk
Luoghi di danza
No full textWriter, journalist, theater and film critic, Marco Ramperti is one of the few that deals with dance in the Italian press of the fascist period. For the newspaper «La Stampa», between 1926 and 1928, he edits the column Luoghi di danza (dance venues), dedicated to ballroom and modern dances. The article investigates the performative nature of Ramperti’s writing, dominated by “staging” devices of the subject matter, as well as by an intrusive presence of the body, first of all that of the author. What emerges is an unprecedented image of the dance in the Twenties, at the same time catalysing the most alienating - and Pirandellian - aspects of modernity, but also a place where genuinely experiencing themselves and the others
