Elementi postmoderni nell'horror americano contemporaneo. Forme testuali e culturali della mutazione 1968-1998

This research argues for an analysis of textual and cultural forms in the American horror film (1968- 1998), by defining the so-called postmodern characters. The “postmodern” term will not mean a period of the history of cinema, but a series of forms and strategies recognizable in many American films. From a bipolar re-mediation and cognitive point of view, the postmodern phenomenon is been considered as a formal and epistemological re-configuration of the cultural “modern” system. The first section of the work examines theoretical problems about the “postmodern phenomenon” by defining its cultural and formal constants in different areas (epistemology, economy, mass-media): the character of convergence, fragmentation, manipulation and immersion represent the first ones, while the “excess” is the morphology of the change, by realizing the “fluctuation” of the previous consolidated system. The second section classifies the textual and cultural forms of American postmodern film, generally non-horror. The “classic narrative” structure – coherent and consequent chain of causal cues toward a conclusion – is scattered by the postmodern constant of “fragmentation”. New textual models arise, fragmenting the narrative ones into the aggregations of data without causal-temporal logics. Considering the process of “transcoding”1 and “remediation”2 between media, and the principle of “convergence” in the phenomenon, the essay aims to define these structures in postmodern film as “database forms” and “navigable space forms.” The third section applies this classification to American horror film (1968-1998). The formal constant of “excess” in the horror genre works on the paradigm of “vision”: if postmodern film shows a crisis of the “truth” in the vision, in horror movies the excess of vision becomes “hyper-vision” – that is “multiplication” of the death/blood/torture visions – and “intra-vision”, that shows the impossibility of recognizing the “real” vision from the virtual/imaginary. In this perspective, the textual and cultural forms and strategies of postmodern horror film are predominantly: the “database-accumulation” forms, where the events result from a very simple “remote cause” serving as a pretext (like in Night of the Living Dead); the “database-catalogue” forms, where the events follow one another displaying a “central” character or theme. In the first case, the catalogue syntagms are connected by “consecutive” elements, building stories linked by the actions of a single character (usually the killer), or connected by non-consecutive episodes about a general theme: examples of the first kind are built on the model of The Wizard of Gore; the second ones, on the films such as Mario Bava’s I tre volti della paura. The “navigable space” forms are defined: hyperlink a, where one universe is fluctuating between reality and dream, as in Rosemary’s Baby; hyperlink b (where two non-hierarchical universes are convergent, the first one real and the other one fictional, as in the Nightmare series); hyperlink c (where more worlds are separated but contiguous in the last sequence, as in Targets); the last form, navigable-loop, includes a textual line which suddenly stops and starts again, reflecting the pattern of a “loop” (as in Lost Highway). This essay analyses in detail the organization of “visual space” into the postmodern horror film by tracing representative patterns. It concludes by examining the “convergence”3 of technologies and cognitive structures of cinema and new media.

EoR in alternative cosmological scenarios

The aim of this Thesis is to investigate the possibility that the observations related to the epoch of reionization can probe not only the evolution of the IGM state, but also the cosmological background in which this process occurs. In fact, the history of the IGM ionization is indeed affected by the evolution of the sources of ionizing photons that, under the assumption of a structure formation paradigm determined by the hierarchic growth of the matter uctuations, results strongly dependent on the characteristics of the background universe. For the purpose of our investigation, we have analysed the reionization history in innovative cosmological frameworks, still in agreement with the recent observational tests related to the SNIa and the CMB probes, comparing our results with the reionization scenario predicted by the commonly used LCDM cosmology. In particular, in this Thesis we have considered two different alternative universes. The first one is a at universe dominated at late epochs by a dynamic dark energy component, characterized by an equation of state evolving in time. The second cosmological framework we have assumed is a LCDM characterized by a primordial overdensity field having a non-Gaussian probability distribution. The reionization scenario have been investigated, in this Thesis, through semi-analytic approaches based on the hierarichic growth of the matter uctuations and on suitable assumptions concerning the ionization and the recombination of the IGM. We make predictions for the evolution and the distribution of the HII regions, and for the global features of reionization, that can be constrained by future observations. Finally, we brie y discuss the possible future prospects of this Thesis work.

In nome della comunità. Analisi dei testi della sicurezza e del terrorismo

The focus of this dissertation is the relationship between the necessity for protection and the construction of cultural identities. In particular, by cultural identities I mean the representation and construction of communities: national communities, religious communities or local communities. By protection I mean the need for individuals and groups to be reassured about dangers and risks. From an anthropological point of view, the relationship between the need for protection and the formation and construction of collective identities is driven by the defensive function of culture. This was recognized explicitly by Claude Lévi-Strauss and Jurij Lotman. To explore the “protective hypothesis,” it was especially useful to compare the immunitarian paradigm, proposed by Roberto Esposito, with a semiotic approach to the problem. According to Esposito, immunity traces borders, dividing Community from what should be kept outside: the enemies, dangers and chaos, and, in general, whatever is perceived to be a threat to collective and individual life. I recognized two dimensions in the concept of immunity. The first is the logic dimension: every element of a system makes sense because of the network of differential relations in which it is inscribed; the second dimension is the social praxis of division and definition of who. We are (or what is inside the border), and who They are (or what is, and must be kept, outside the border). I tested my hypothesis by analyzing two subject areas in particular: first, the security practices in London after 9/11 and 7/7; and, second, the Spiritual Guide of 9/11 suicide bombers. In both cases, one observes the construction of two entities: We and They. The difference between the two cases is their “model of the world”: in the London case, one finds the political paradigms of security as Sovereignty, Governamentality and Biopolitics. In the Spiritual Guide, one observes a religious model of the Community of God confronting the Community of Evil. From a semiotic point view, the problem is the origin of respective values, the origin of respective moral universes, and the construction of authority. In both cases, I found that emotional dynamics are crucial in the process of forming collective identities and in the process of motivating the involved subjects: specifically, the role of fear and terror is the primary factor, and represents the principal focus of my research.

Nothing ever ends: il concetto di fine negli universi seriali

L'oggetto principale di questa tesi è il concetto di fine negli universi seriali. Spesso si intende il “The End” in un romanzo o in un film come un momento climatico, e che i finali sono collegati ad una teleologia che guida il testo nel suo insieme. Come risultato di questo modo di approcciare i finale, una delle opinioni più comuni è simile a quella di Henry James [1884] che diceva: “distribution at the last of prizes, pensions, husbands, wives, babies, millions, appended paragraph, and cheerful remarks”. Ma è molto difficile applicare la posizione di James a un romanzo modernista o a un film postmoderno e ancor ameno ai cosiddetti universi narrativi seriali, in cui la storia si sviluppa lungo decenni. Nel nostro contemporaneo panorama mediale, il testo non è più concepito come un'opera, ma deve essere costruito e concepito come un network, un ecosistema in cui nuove connessioni economiche e nuove relazioni bottom-up modellano una struttura inedita. Questa nuova struttura può riconfigurare il senso del finale e della fine, ma anche per le vast narratives spesso si dice che “Il finale non corrispondeva alla spirito della storia”, “il finale era deludente”. Potremmo sostenere che il concetto di finale sia ancora importante, nonostante sia stato superato dal punto di vista teorico. Per analizzare se il finale è costruito in un maniera non-lineare ma percepito come teleologico, la tesi è strutturata in due parti e di quattro capitoli. Prima parte “Storia” [1. Letteratura; 2. Cinema], seconda “Forme/strutture” [3. Transmedia; 4. Remix]

Expériences du sacré et (dé)figurations du Christ. Artaud, Beckett, Pasolini

« Dieu est mort » proclame à l’envi le fou nietzschéen. C’est sous l’égide inquiète de cette assertion paroxystique, traduisant ce «malaise de la culture» qu’évoquait Freud, que la pensée, la littérature et l’art du XXe siècle européen évoluent. Cependant, le christianisme dont ce cri signe l’extrême décadence, n’est pas seul à imprégner les productions artistiques de ce siècle, même les plus prétendument athées, mais avant tout la figure du Christ - autour de laquelle sont structurés tant cette religion que son système de croyance – semble, littéralement et paradoxalement, infester l’imaginaire du XXe siècle, sous des formes plus ou moins fantasmatiques. Ce travail se propose ainsi précisément d’étudier, dans une optique interdisciplinaire entre littérature, art et cinéma, cette dynamique controversée, ses causes, les processus qui la sous-tendent ainsi que ses effets, à partir des œuvres de trois auteurs : Artaud, Beckett et Pasolini. L’objectif est de fournir une clé de lecture de cette problématique qui mette en exergue comment « la conversion de la croyance », comme la définit Deleuze, à laquelle ces auteurs participent, n’engendre pas un rejet purement profanatoire du christianisme mais, à l’inverse, la mise en œuvre d’un mouvement aussi violent que libératoire qualifié par Nancy de « déconstruction du christianisme ». Ce travail entend donc étudier tout d’abord à la lumière de l’expérience intérieure de Bataille, l’imaginaire christique qui sous-tend leurs productions ; puis, d’en analyser les mouvements et les effets en les questionnant sur la base de cette dynamique ambivalente que Grossman nomme la « défiguration de la forme christique ». Les excès délirants d’Artaud, l’ironie tranchante de Beckett et la passion ambiguë de Pasolini s’avèrent ainsi participer à un mouvement commun qui, oscillant entre reprise et rejet, débouche sur une attitude tout aussi destructive que revitalisante des fondements du christianisme.
