This thesis brings together feminist documentary film theory and feminist new materialism(s) to describe how feminist material-discursive practices in a sample of Spanish and Italian documentary cinema made between 2013-2018 (can) visualise gender in/equalities. The accomplished objectives have been: 1. Building a bridge between feminist documentary film theory and Karen Barad’s diffractive methodology by approaching non-fiction cinema that deals with social inequalities as a diffraction apparatus. 2. Developing a feminist toolbox for a response-able gaze by gathering different insights from feminist film theory. 3. Identifying feminist material-discursive practices in a sample of documentary films produced in Spain and Italy over the last six years (2013-2018). 4. Analysing the effects that these feminist material-discursive practices in documentary cinema have, particularly in terms of visualising gender in/equalities on both sides of the camera and on both sides of the screen. 5. Revealing patterns between the ten case studies by reading through one another (i.e. diffractively) insights raised in each one of them. In ten documentary films/case studies, I identify patterns of continuities and differences concerning feminist material-discursive practices at four levels: content, form, production and reception. In terms of contents, I detect two patterns in which feminist material-discursive practices may operate: enacting the right to appear or enacting the right to look back and/or against the grain. As for the forms, I exemplify how feminism politicises Bill Nichols’s six modes of representation. My analysis of production practices is elaborated along the filmmakers’ self-positions/situatedness, tensions/obstructions, and effects/affects/emotions regarding four key concepts: documentary cinema, equality, gender and feminism(s). And in the case of reception practices, I identify patterns of affective identification and/or intellectual reflections.

Our research takes place in the context of a discipline kwown as Communication for Development, sited inside the field of Communication for Social Change, characterized by the use of interpersonal ad mass communication theories and tools, applyied to international development cooperation. Our study aims at pointing out a change of paradigm in this field: our object is Public Administration’s communication, therefore, what we suggest is a shift from Communication for Development, to Development Communication. The object of our study, hence, becomes the discourse itself, in its double action of representation and construction of reality. In particular, we are interested in the discourse’s tribute to the creation of a collective immagination, wich is the perspective towards which we have oriented the analysis, through a structuralist semoitics-based methodology integrated with a socio-semiotic approach. Taking into consideartion the fact that in our contemporary society (that is to say a ‘Western’ and ‘First World’ society), the internet is a crucial public space for the mediation and the management of collective immagination, we chose the web sites of Public Bodies which are dedicated to International Cooperation has our analysis corpus. This, due to their symbolic and ideologic significance, as well as for the actual political responsibility we think these web sites should have. The result of our analysis allows us to suggest some discoursive strategies used in the web sites of Public Bodies. In these sites, there is a tendency to shift the discourses around international cooperation from the ideological axis - avoiding in so doing to explicit a political statement about the causes of injustices and un-balances which lead to the necessity of a support in development (i.e. avoiding to mention values such as social justice and democracy while acknowledging socio-economical institutions which contribute to foster underdevelopment on a global scale) -, to the ethical axis, hence referring to moral values concerning the private sphere (human solidarity and charity), which is delegated mainly to non governamental associations.

This study concerns the representation of space in Caribbean literature, both francophone and Anglophone and, in particular, but not only, in the martinican literature, in the works of the authors born in the island. The analysis focus on the second half of the last century, a period in which the martinican production of novels and romances increased considerably, and where the representation and the rule of space had a relevant place. So, the thesis explores the literary modalities of this representation. The work is constituted of 5 chapters and the critical and methodological approaches are both of an analytical and comparative type. The first chapter “The caribbean space: geography, history and society” presents the geographic context, through an analysis of the historical and political major events occurred in the Caribbean archipelago, in particular of the French Antilles, from the first colonization until the départementalisation. The first paragraph “The colonized space: historical-political excursus” the explores the history of the European colonization that marked forever the theatre of the relationship between Europe, Africa and the New World. This social situation take a long and complex process of “Re-appropriation and renegotiation of the space”, (second paragraph) always the space of the Other, that interest both the Antillean society and the writers’ universe. So, a series of questions take place in the third paragraph “Landscape and identity”: what is the function of space in the process of identity construction? What are the literary forms and representations of space in the Caribbean context? Could the writing be a tool of cultural identity definition, both individual and collective? The second chapter “The literary representation of the Antillean space” is a methodological analysis of the notions of literary space and descriptive gender. The first paragraph “The literary space of and in the novel” is an excursus of the theory of such critics like Blanchot, Bachelard, Genette and Greimas, and in particular the recent innovation of the 20th century; the second one “Space of the Antilles, space of the writing” is an attempt to apply this theory to the Antillean literary space. Finally the last paragraph “Signs on the page: the symbolic places of the antillean novel landscape” presents an inventory of the most recurrent antillean places (mornes, ravines, traces, cachots, En-ville,…), symbols of the history and the past, described in literary works, but according to new modalities of representation. The third chapter, the core of the thesis, “Re-drawing the map of the French Antilles” focused the study of space representation on francophone literature, in particular on a selected works of four martinican writers, like Roland Brival, Édouard Glissant, Patrick Chamoiseau and Raphaël Confiant. Through this section, a spatial evolution comes out step by step, from the first to the second paragraph, whose titles are linked together “The novel space evolution: from the forest of the morne… to the jungle of the ville”. The virgin and uncontaminated space of the Antilles, prior to the colonisation, where the Indios lived in harmony with the nature, find a representation in both works of Brival (Le sang du roucou, Le dernier des Aloukous) and of Glissant (Le Quatrième siècle, Ormerod). The arrival of the European colonizer brings a violent and sudden metamorphosis of the originary space and landscape, together with the traditions and culture of the Caraïbes population. These radical changes are visible in the works of Chamoiseau (Chronique des sept misères, Texaco, L’esclave vieil homme et le molosse, Livret des villes du deuxième monde, Un dimanche au cachot) and Confiant (Le Nègre et l’Amiral, Eau de Café, Ravines du devant-jour, Nègre marron) that explore the urban space of the creole En-ville. The fourth chapter represents the “2nd step: the Anglophone novel space” in the exploration of literary representation of space, through an analytical study of the works of three Anglophone writers, the 19th century Lafcadio Hearn (A Midsummer Trip To the West Indies, Two Years in the French West Indies, Youma) and the contemporary authors Derek Walcott (Omeros, Map of the New World, What the Twilight says) and Edward Kamau Brathwaite (The Arrivants: A New World Trilogy). The Anglophone voice of the Caribbean archipelago brings a very interesting contribution to the critical idea of a spatial evolution in the literary representation of space, started with francophone production: “The spatial evolution goes on: from the Martiniques Sketches of Hearn… to the modern bards of Caribbean archipelago” is the new linked title of the two paragraphs. The fifth chapter “Extended look, space shared: the Caribbean archipelago” is a comparative analysis of the results achieved in the prior sections, through a dialogue between all the texts in the first paragraph “Francophone and Anglophone representation of space compared: differences and analogies”. The last paragraph instead is an attempt of re-negotiate the conventional notions of space and place, from a geographical and physical meaning, to the new concept of “commonplace”, not synonym of prejudice, but “common place” of sharing and dialogue. The question sets in the last paragraph “The “commonplaces” of the physical and mental map of the Caribbean archipelago: toward a non-place?” contains the critical idea of the entire thesis.

Purpose of this research is to deepen the study on the section in architecture. The survey aims as important elements in the project Teatro Domestico by Aldo Rossi built for the XVII Triennale di Milano in 1986 and, through the implementation on several topics of architecture, verify the timeliness and fertility in the new compositional exercises. Through the study of certain areas of the Rossi’s theory we tried to find a common thread for the reading of the theater project. The theater is the place of the ephemeral and the artificial, which is why his destiny is the end and the fatal loss. The design and construction of theater setting has always had a double meaning between the value of civil architecture and testing of new technologies available. Rossi's experience in this area are clear examples of the inseparable relationship between the representation of architecture as art and design of architecture as a model of reality. In the Teatro Domestico, the distinction between representation and the real world is constantly canceled and returned through the reversal of the meaning and through the skip of scale. At present, studies conducted on the work of Rossi concern the report that the architectural composition is the theory of form, focusing compositional development of a manufacturing process between the typological analysis and form invention. The research, through the analysis of some projects few designs, will try to analyze this issue through the rules of composition both graphical and concrete construction, hoping to decipher the mechanism underlying the invention. The almost total lack of published material on the project Teatro Domestico and the opportunity to visit the archives that preserve the drawings, has allowed the author of this study to deepen the internal issues in the project, thus placing this search as a first step toward possible further analysis on the works of Rossi linked to performance world. The final aim is therefore to produce material that can best describe the work of Rossi. Through the reading of the material published by the same author and the vision of unpublished material preserved in the archives, it was possible to develop new material and increasing knowledge about the work, otherwise difficult to analyze. The research is divided into two groups. The first, taking into account the close relationship most frequently mentioned by Rossi himself between archeology and architectural composition, stresses the importance of tipo such as urban composition reading system as well as open tool of invention. Resuming Ezio Bonfanti’s essay on the work of the architect we wanted to investigate how the paratactic method is applied to the early work conceived and, subsequently as the process reaches a complexity accentuated, while keeping stable the basic terms. Following a brief introduction related to the concept of the section and the different interpretations that over time the term had, we tried to identify with this facility a methodology for reading Rossi’s projects. The result is a constant typological interpretation of the term, not only related to the composition in plant but also through the elevation plans. The section is therefore intended as the overturning of such elevation is marked on the same plane of the terms used, there is a different approach, but a similarity of characters. The identification of architectural phonemes allows comparison with other arts. The research goes in the direction of language trying to identify the relationship between representation and construction, between the ephemeral and the real world. In this sense it will highlight the similarities between the graphic material produced by Ross and some important examples of contemporary author. The comparison between the composition system with the surrealist world of painting and literature will facilitate the understanding and identification of possible rules applied by Rossi. The second part of the research is characterized by a focus on the intent of the project chosen. Teatro Domestico embodies a number of elements that seem to conclude (assuming an end point but also to start) a curriculum author. With it, the experiments carried out on the theater started with the project for the Teatrino Scientifico (1978) through the project for the Teatro del Mondo (1979), into a Laic Tabernacle representative collective and private memory of the city. Starting from a reading of the draft, through the collection of published material, we’ve made an analysis on the explicit themes of the work, finding the conceptual references. Following the taking view of the original materials not published kept at Aldo Rossi's Archive Collection of the Canadian Center for Architecture in Montréal, will be implemented through the existing techniques for digital representation, a virtual reconstruction of the project, adding little to the material, a new element for future studies. The reconstruction is part of a larger research studies where the current technologies of composition and representation in architecture stand side by side with research on the method of composition of this architect. The results achieved are in addition to experiences in the past dealt with the reconstruction of some of the lost works of Aldo Rossi. A partial objective is to reactivate a discourse around this work is considered non-principal, among others born in the prolific activities. Reassessment of development projects which would bring the level of ephemeral works most frequented by giving them the value earned. In conclusion, the research aims to open a new field of interest on the part not only as a technical instrument of representation of an idea but as an actual mechanism through which composition is formed and the idea is developed.

Il campo d’interesse della ricerca è stato l’attuale processo di ricentralizzazione del Social Housing nelle periferie urbane in una parte del contesto internazionale, che sembra stia portando le città a ricrearsi e ripensarsi grazie alla presa di coscienza delle differenze esistenti, rispetto al passato, nei nuovi processi di trasformazione nei quali la città è intesa sia come spazio costruito ma anche sociale. In virtù di quest’ultimi due aspetti complementari della città, oggi, il ruolo della periferia contemporanea sembra essere diversamente interpretato, così come gli interventi di riqualificazione di tipo assistenziale - migliorativo tenderebbero a trasformarne i suoi caratteri alla ricerca del “modello di città”. L’interesse alla tematica è inoltre scaturito dalla constatazione che alla base della crisi dei modelli d’intervento pubblico starebbero sia l’insostenibilità economica ma soprattutto l’errata lettura dei bisogni delle famiglie nella loro specificità e diversità e che in tal senso l’eventuale partecipazione della cittadinanza costituirebbe effettivamente una proposta valida, anche per risolvere la crescente domanda abitativa che si pone a livello mondiale. L’obiettivo della ricerca è stato quello d’analizzare, nel contesto internazionale del Social Housing, le caratteristiche di partecipazione e sussidiarietà che connotano particolarmente gli interventi di riqualificazione destinati a famiglie economicamente carenti, nello specifico analizzando i metodi e gli strumenti atti alla comunicazione partecipativa del progetto in aree urbane periferiche italiane e brasiliane. Nella prima e seconda fase della ricerca è stato svolto, rispettivamente, un lavoro di analisi bibliografica sul tema dell’emergenza casa e sulle nuove politiche abitative di sviluppo urbano ed uno specifico sulla tematica della riqualificazione partecipata del Social Housing in aree della periferia urbana, infine nella terza fase sono stati analizzati i casi di studio prescelti dando rilievo all’analisi delle caratteristiche e requisiti prestazionali delle tecniche partecipative di rappresentazione - comunicazione, più idonee ad influenzare positivamente il suddetto processo.

This thesis gives an overview of the history of gold per se, of gold as an investment good and offers some institutional details about gold and other precious metal markets. The goal of this study is to investigate the role of gold as a store of value and hedge against negative market movements in turbulent times. I investigate gold’s ability to act as a safe haven during periods of financial stress by employing instrumental variable techniques that allow for time varying conditional covariance. I find broad evidence supporting the view that gold acts as an anchor of stability during market downturns. During periods of high uncertainty and low stock market returns, gold tends to have higher than average excess returns. The effectiveness of gold as a safe haven is enhanced during periods of extreme crises: the largest peaks are observed during the global financial crises of 2007-2009 and, in particular, during the Lehman default (October 2008). A further goal of this thesis is to investigate whether gold provides protection from tail risk. I address the issue of asymmetric precious metal behavior conditioned to stock market performance and provide empirical evidence about the contribution of gold to a portfolio’s systematic skewness and kurtosis. I find that gold has positive coskewness with the market portfolio when the market is skewed to the left. Moreover, gold shows low cokurtosis with the market returns during volatile periods. I therefore show that gold is a desirable investment good to risk averse investors, since it tends to decrease the probability of experiencing extreme bad outcomes, and the magnitude of losses in case such events occur. Gold thus bears very important and under-researched characteristics as an asset class per se, which this thesis contributed to address and unveil.

Esta investigación tuvo como objetivo general develar las representaciones sociales sobre la Medicina Popular en tres grupos poblacionales, pacientes oncológicos (n=100), familiares de los pacientes (n=25) y miembros del equipo de salud (n=26). Para ello, se realizaron tres estudios cualitativos con cada grupo poblacional y un cuarto en el que se describen las similitudes y las diferencias entre ellos en relación con el objeto de representación. En general, se utilizaron entrevistas en profundidad, ejercicios de asociaciones libres y grupos focales (7 con 62 pacientes). Resultados: paciente oncológico: Medicina Popular representada como una salida optimista a la angustiante situación que está viviendo frente al cáncer; una apuesta a la vida. Para la familia: una contra capaz de mantener con vida y fortaleza al paciente y para el equipo de salud, una realidad incombatible de los pacientes y de la familia, que tiene efecto placebo sobre ellos y que está relacionada con el pensamiento mágico religioso, la fé y la ignorancia de quienes la realizan. En cuanto a las diferencias, el paciente y la familia consideran que la Medicina Popular es una alternativa en la que depositan su fé y confianza; el personal de salud no cree en sus efectos sobre el cáncer y la considera como estafa y engaño para el paciente. En las similitudes, todos coinciden en que es una alternativa, generadora de esperanza, basada en compuestos naturales que le permiten al paciente contribuir a la curación del cáncer y a sobrellevar el malestar provocado por la quimioterapia. Finalmente, se presentan conclusiones generales, se discuten algunos de los hallazgos y la importancia de las RS de la Medicina Popular y su impacto sobre la atención y la calidad de vida del paciente y se plantean algunos interrogantes que podrían favorecer el desarrollo de una línea de investigación en el tema.

La publication de nombreuses œuvres, à la fois littéraires et picturales, entre 1870 et 1914, inspirées par l’épisode biblique du meurtre de Jean Baptiste par Salomé, s’inscrit dans une crise qui touche à cette époque, en Europe, aussi bien le sujet que la notion de représentation. Le mythe de Salomé permet de poursuivre une réflexion de nature littéraire, historique et esthétique concernant le processus d’autonomisation de l’art. À partir des sources bibliques et antiques, dans lesquelles Salomé et Jean Baptiste incarnent respectivement le monde païen en conflit avec le monde chrétien, ces deux personnages font graduellement leur entrée dans l’univers de la fiction. Ils sont au cœur de la transition d’une lecture transcendante — reliée particulièrement à la tradition catholique — de l’épisode tragique qui les unit, à une lecture immanente qui en fait deux instances purement esthétiques. La danseuse et le dernier des prophètes émergent dans la littérature et dans l’art occidentaux comme deux pôles symboliques, liés l’un à l’autre par différents types de relation, susceptibles d’être librement réinvestis par de nouvelles significations et à l’écart des conventions. Si, dans la première partie du XIXe siècle, Salomé et Jean Baptiste sont encore liés à leur sens orthodoxe, au tournant du siècle ils finissent par s’autonomiser de l’Écriture et donnent lieu à de multiples récritures et à des adaptations inattendues. Celles-ci ressortissent alors moins du blasphème à proprement parler que d’un témoignage emblématique d’une transformation du rapport que l’artiste entretient avec son œuvre. Celui-ci, en s’identifiant avec le prophète décollé, se mesure à l’œuvre d’art, qui est incarnée par Salomé. La relation entre Salomé et Jean Baptiste, dans ces diverses représentations, exprime et reflète le moment où art et littérature se reconnaissent comme fictions.

Oggetto di questa tesi è l’analisi delle modalità di rappresentazione del trauma nel romanzo del Novecento e, in particolare, nelle opere di Samuel Beckett, Georges Perec e Agota Kristof. Fondamento dello studio sarà una disamina dei procedimenti linguistici e narrativi di rappresentazione del trauma nelle prose degli autori citati, al fine tracciare le linee di un’estetica in grado di descrivere le caratteristiche peculiari delle narrazioni in cui la dimensione antinarrativa della memoria traumatica assume il ruolo di principio estetico guida. L’analisi si soffermerà sulla cruciale relazione esistente, in tutti e tre gli autori, tra rappresentazione del trauma e sviluppo di strategie narrativi definibili come “denegative”. L’analisi dei testi letterari è condotta sulla base del corpus critico dei Trauma Studies, dell’ermeneutica della narrazione di stampo ricœuriano e della teoria del linguaggio psicoanalitica e affiancata, ove possibile, da uno studio filologico-genetico dei materiali d’autore. Alla luce di tali premesse, intendo rivalutare il carattere rappresentativo e testimoniale della letteratura del secolo scorso, in contrasto con la consuetudine a vedere nel romanzo novecentesco il trionfo dell’antimimesi e il declino del racconto. Dal momento che le narrazioni traumatiche si costruiscono intorno e attraverso i vuoti di linguaggio, la tesi è che siano proprio questi vuoti linguistici e narrativi (amnesie, acronie, afasie, lapsus, omissioni e mancanze ancora più sofisticate come nel caso di Perec) a rappresentare, in modo mimetico, la realtà apparentemente inaccessibile del trauma. Si tenterà di dimostrare come questi nuovi canoni di rappresentazione non denuncino l’impossibilità del racconto, bensì una sfida al silenzio, celata in più sottili e complesse convenzioni narrative, le quali mantengono un rapporto di filiazione indiretto − per una via che potremmo definire denegativa − con quelle del romanzo tradizionale.

The aim of this thesis is to investigate the nature of quantum computation and the question of the quantum speed-up over classical computation by comparing two different quantum computational frameworks, the traditional quantum circuit model and the cluster-state quantum computer. After an introductory survey of the theoretical and epistemological questions concerning quantum computation, the first part of this thesis provides a presentation of cluster-state computation suitable for a philosophical audience. In spite of the computational equivalence between the two frameworks, their differences can be considered as structural. Entanglement is shown to play a fundamental role in both quantum circuits and cluster-state computers; this supports, from a new perspective, the argument that entanglement can reasonably explain the quantum speed-up over classical computation. However, quantum circuits and cluster-state computers diverge with regard to one of the explanations of quantum computation that actually accords a central role to entanglement, i.e. the Everett interpretation. It is argued that, while cluster-state quantum computation does not show an Everettian failure in accounting for the computational processes, it threatens that interpretation of being not-explanatory. This analysis presented here should be integrated in a more general work in order to include also further frameworks of quantum computation, e.g. topological quantum computation. However, what is revealed by this work is that the speed-up question does not capture all that is at stake: both quantum circuits and cluster-state computers achieve the speed-up, but the challenges that they posit go besides that specific question. Then, the existence of alternative equivalent quantum computational models suggests that the ultimate question should be moved from the speed-up to a sort of “representation theorem” for quantum computation, to be meant as the general goal of identifying the physical features underlying these alternative frameworks that allow for labelling those frameworks as “quantum computation”.

Dans l’Antiquité, la recherche sur la technique permet les premières réalisations de dispositifs ingénieux, tels que des appareils qui accomplissent une série d’actions par le biais de stimulus externes et de mécanismes cachés. Les organismes politiques et religieux saisissent rapidement la puissance communicative de ces machines, en devenant les promoteurs et patrons privilégiés de leur production. L’Empire sassanide (224-650) ne constitue pas une exception. En effet, les souverains perses consacrent, au moins à l’époque tardive, une grande attention à la conception et au déploiement de dispositifs savants. De même, un siècle plus tard, dans le milieu du califat islamique, les Abbassides (750-1258) semblent s’entourer de tels dispositifs. La continuité entre les deux empires dans plusieurs domaines, de la théorie politique à l’administration, est bien connue. Cependant, la question de la réutilisation du patrimoine technique et scientifique ancien, et notamment sassanide, par la cour abbasside, demeure encore largement inexplorée. L’étude d’un corpus de sources, aussi vaste qu’hétérogène, rassemblant des ouvrages historiographiques, géographiques, poétiques et d’adab, ainsi que des traités scientifiques et techniques en plusieurs langues, permet d’analyser différents aspects de la production et de l’usage politique des machines. Au sein de la cour sassanide, comme de la cour abbasside, la machine s’avère constituer un véhicule préférentiel de représentation et de diffusion de l’idéologie politique. À travers sa mise en scène publique, elle contribue de manière substantielle à la définition de l’espace du pouvoir, en participant à la création d’une image de la cour comme un microcosme au cœur duquel le Roi des rois, et plus tard le calife, occupaient le rôle cardinal de maître incontesté du monde. La continuité entre les empires sassanide et abbasside dans le domaine technique ne se limite donc pas à une récupération de savoirs, mais s’opère aussi sous la forme d’une véritable réactivation d’un patrimoine symbolique

By using a symbolic method, known in the literature as the classical umbral calculus, a symbolic representation of Lévy processes is given and a new family of time-space harmonic polynomials with respect to such processes, which includes and generalizes the exponential complete Bell polynomials, is introduced. The usefulness of time-space harmonic polynomials with respect to Lévy processes is that it is a martingale the stochastic process obtained by replacing the indeterminate x of the polynomials with a Lévy process, whereas the Lévy process does not necessarily have this property. Therefore to find such polynomials could be particularly meaningful for applications. This new family includes Hermite polynomials, time-space harmonic with respect to Brownian motion, Poisson-Charlier polynomials with respect to Poisson processes, Laguerre and actuarial polynomials with respect to Gamma processes , Meixner polynomials of the first kind with respect to Pascal processes, Euler, Bernoulli, Krawtchuk, and pseudo-Narumi polynomials with respect to suitable random walks. The role played by cumulants is stressed and brought to the light, either in the symbolic representation of Lévy processes and their infinite divisibility property, either in the generalization, via umbral Kailath-Segall formula, of the well-known formulae giving elementary symmetric polynomials in terms of power sum symmetric polynomials. The expression of the family of time-space harmonic polynomials here introduced has some connections with the so-called moment representation of various families of multivariate polynomials. Such moment representation has been studied here for the first time in connection with the time-space harmonic property with respect to suitable symbolic multivariate Lévy processes. In particular, multivariate Hermite polynomials and their properties have been studied in connection with a symbolic version of the multivariate Brownian motion, while multivariate Bernoulli and Euler polynomials are represented as powers of multivariate polynomials which are time-space harmonic with respect to suitable multivariate Lévy processes.
