Per un'etica della letteratura: la cornice il doppio legame nell'opera di J. M. Coetzee

The elusive fiction of J. M. Coetzee is not a work in which you can read fixed ethical stances. I suggest testing the potentialities of a logic based on frames and double binds in Coetzee's novels. A double bind is a dilemma in communication which consists on tho conflicting messages, with the result that you can’t successfully respond to neither. Jacques Derrida highlighted the strategic value of a way of thinking based on the double bind (but on frames as well), which enables to escape binary thinking and so it opens an ethical space, where you can make a choice out of a set of fixed rules and take responsibility for it. In Coetzee’s fiction the author himself can be considered in a double bind, seeing that he is a white South African writer who feels that his “task” can’t be as simply as choosing to represent faithfully the violence and the racism of the apartheid or of choosing to give a voice to the oppressed. Good intentions alone do not ensure protection against entering unwittingly into complicity with the dominant discourse, and this is why is important to make the frame in which one is always situated clearly visible and explicit. The logic of the double bind becomes the way in which moral problem are staged in Coetzee’s fiction as well: the opportunity to give a voice to the oppressed through the same language which co-opted to serve the cause of oppression, a relation with the otherness never completed, or the representability of evil in literature, of the secret and of the paradoxical implications of confession and forgiveness.

Reasoning with incomplete and imprecise preferences

Preferences are present in many real life situations but it is often difficult to quantify them giving a precise value. Sometimes preference values may be missing because of privacy reasons or because they are expensive to obtain or to produce. In some other situations the user of an automated system may have a vague idea of whats he wants. In this thesis we considered the general formalism of soft constraints, where preferences play a crucial role and we extended such a framework to handle both incomplete and imprecise preferences. In particular we provided new theoretical frameworks to handle such kinds of preferences. By admitting missing or imprecise preferences, solving a soft constraint problem becomes a different task. In fact, the new goal is to find solutions which are the best ones independently of the precise value the each preference may have. With this in mind we defined two notions of optimality: the possibly optimal solutions and the necessary optimal solutions, which are optimal no matter we assign a precise value to a missing or imprecise preference. We provided several algorithms, bases on both systematic and local search approaches, to find such kind of solutions. Moreover, we also studied the impact of our techniques also in a specific class of problems (the stable marriage problems) where imprecision and incompleteness have a specific meaning and up to now have been tackled with different techniques. In the context of the classical stable marriage problem we developed a fair method to randomly generate stable marriages of a given problem instance. Furthermore, we adapted our techniques to solve stable marriage problems with ties and incomplete lists, which are known to be NP-hard, obtaining good results both in terms of size of the returned marriage and in terms of steps need to find a solution.

La goutte et la feuille. Transfigurations de la beauté naturelle dans la littérature européenne: Chateaubriand, Hölderlin et Leopardi.

La goutte et la feuille . Transfigurations de la beauté naturelle dans la littérature européenne : Chateaubriand , Hölderlin et Leopardi . La thèse se présente comme une étude morphologique de l'esthétique de la nature à la fin de 18 ans. Siècle. Le dénominateur commun est une étude comparative des paradigmes scientifiques et des images symboliques utilisés dans la littérature européenne . Sous ce point de vue la thèse identifie les formes originaires de la goutte et de la feuille comme un point de contact entre des moments culturels distincts, même si entrelacés. Un passage particulièrement important du travail est l'analyse structurelle du paysage . Le paysage est le point culminant d'accès aux secrets de l'écriture romantique. Le paysage commence avec la représentation classique du jardin édénique et se termine avec la forêt exotique américaine. Celle-ci est décrite par Chateaubriand, en tant qu’objet d’une KOINONIE stylistique à l’immensité sublime du désert et l'océan . Hölderlin place avec la beauté naturelle devient une harmonie secrète et sombre dans l'inconscient symbolique de l'âme humaine . Leopardi est l'auteur du désenchantement , et pourtant il est encore capable de pressentir empathiquement la mesure de l’imagination envers la beauté naturelle. Avec Léopards , cependant, s’accomplit la séparation finale entre l’EPOS de la beauté naturelle et l’ETHOS de la nature . Cette dernière est une grandeur morale, et au fait elle représente le moment de la dissolution nihiliste, notamment magnitude de l’esthétique typiquement romantique . Après Chateaubriand , Leopardi , et Hölderlin beauté naturelle ne seront plus transfigurant .

A Law and Economics Analysis of Trade Secrets: Optimal Scope of Law, Misappropriation and Alternative Damages Regimes

This thesis is primarily based on three core chapters, focused on the fundamental issues of trade secrets law. The goal of this thesis is to come up with policy recommendations to improve legal structure governing trade secrets. The focal points of this research are the following. What is the optimal scope of trade secrets law? How does it depend on the market characteristics such as degree of product differentiation between competing products? What factors need to be considered to balance the contradicting objectives of promoting innovation and knowledge diffusion? The second strand of this research focuses on the desirability of lost profits or unjust enrichment damage regimes in case of misappropriation of a trade secret. A comparison between these regimes is made and simple policy implications are extracted from the analysis. The last part of this research is an empirical analysis of a possible relationship between trade secrets sharing and misappropriation instances faced by firms.

Essays on Ethnic Diversity and Development

This dissertation consists of three papers. The first paper "Ethnicity, Migration and Conflict: Evidence from Contemporary South Africa” exploits some of the institutional changes intervened in South Africa during the end of apartheid to investigate the relationship between ethnic diversity and conflict. I find within-ethnic polarization to be significantly related to the intensity of armed confrontations among black-dominated groups. My investigation thus gives strong and robust empirical support to the theoretical arguments which identify ethnic diversity as one of the determinants of civil conflict. The second chapter, "Pre-Colonial Centralization, Colonial Activities and Development in Latin America", investigates the hypothesis that pre-colonial ethnic institutions shaped contemporary regional development in Latin America. I document a strong and positive relationship between pre-colonial centralization and regional development. Results are in line with the view that highly centralized pre-colonial societies acted as a persistent force of agglomeration of economic activities and a strong predictor of colonial state capacity. The results provide a first evidence of the existence of a link between pre-colonial centralization, colonial institutional arrangements and contemporary economic development. The third paper "Bite and Divide: Malaria and Ethnic Diversity” investigates the role of malaria as a fundamental determinant of modern ethnic diversity. This paper explores the hypothesis, that a large exposure to malaria has fostered differential interactions that reduced contacts between groups and increased interactions within them Results document that malaria increases the number of ethnic groups at all levels of spatial disaggregation and time periods (exploiting historical and current ethnic diversity). Regressions' results show that endogamous marriages are more frequent in areas with higher geographic suitability to malaria. The results are in line with the view that malaria increases intra-ethnic interactions while decreasing inter-ethnic ones.

Métamorphoses de l'Image des Tartares dans la littérature européenne du XXème siècle

Ce travail doctoral analyse le changement de l’image des Tartares dans la littérature européenne en langue allemande, anglaise, française et italienne du XXe siècle par l’étude de trois figures : la horde mongole, Gengis-khan et Khoubilaï-khan. Il soutient la thèse que, grâce à quelques facteurs historico-culturels comme la remise en question du concept de barbarie, l’essor des totalitarismes, l’ouverture de la Mongolie vers l’Occident, la redécouverte de l’Histoire secrète des Mongols et la fortune de Le divisament dou monde, au cours du XXe siècle, l’image littéraire des gengiskhanides de négative devient positive. Cette étude se compose d’une introduction, de trois chapitres et d’une conclusion. Dans l’introduction, on analyse la formation de l’image des Tartares et son évolution jusqu’à la fin du XIXe siècle, on retrace les facteurs historico-culturels qui la remettent au goût du jour et en provoquent le changement au XXe siècle et on présente le travail. Dans le premier chapitre, on se penche sur la prosopographie des Tartares dans les textes littéraires du XXe siècle, en la confrontant avec leur représentation dans l’art contemporain. Dans le deuxième chapitre, on étudie la façon des Tartares de se rapporter aux autres au sein de la société dans les textes littéraires du XXe siècle. Dans le troisième chapitre, on examine les lieux des gengiskhanides dans les textes littéraires du XXe siècle. Enfin, dans la conclusion, les données acquises au moyen de l’analyse conduite sont confrontées et interprétées. Le changement de l’image des Tartares va de pair avec une Europe qui, après avoir fait l’expérience de deux guerres mondiales, avoir assisté aux revendications de la décolonisation et avoir introjecté la thèse freudienne du « malaise dans la civilisation », remet en discussion sa façon de concevoir la barbarie et l’Altérité.

Giochi di famiglia: dinamiche di potere tra Augusto e Tiberio

Il lungo processo che avrebbe portato Ottaviano alla conquista del potere e alla fondazione del principato è scandito da alcuni momenti chiave e da diversi personaggi che ne accompagnarono l'ascesa. Prima ancora che sul campo di battaglia, il figlio adottivo di Cesare riuscì a primeggiare per la grande capacità di gestire alleanze e rapporti personali, per la grande maestria con la quale riuscì a passare da capo rivoluzionario a rappresentante e membro dell'aristocrazia tradizionale. Non fu un cammino facile e lineare e forse il compito più difficile non fu sbaragliare gli avversari ad Azio, ma conservare un potere che gli fu costantemente contestato. Ancora dopo il 31 a.C., infatti, in più di un'occasione, Augusto fu chiamato a difendere la sua creatura (il principato) e a procedere a modificarne costantemente base di potere e struttura: solamente attraverso questa fondamentale, minuziosa, ma nascosta opera, egli riuscì a porre le basi per una struttura di potere destinata a durare immutata almeno per un secolo. In base a queste premesse, la ricerca è organizzata secondo un duplice criterio cronologico, inserendo -all'interno della cornice rappresentata dagli eventi- una partizione che tenga presente ulteriori cesure e momenti determinanti. Il proposito è quello di sottolineare come all'interno di un regno unitario, caratterizzato dalla permanenza di un unico sovrano, sia possibile intravedere l'alternarsi di situazioni storiche diverse, di rapporti di forze, alleanze e unioni in virtù delle quali si determinino orientamenti differenti nell'ambito tanto della politica interna quanto di quella esterna.
