International audience ; Although nuclear energy forms an important and controversial part of polar history, its uses and misuses have so far received little attention from professional historians. Especially mobile nuclear reactors, as deployed for instance on the Antarctic continent, played an important role in the conquest of the polar regions. The Antarctic case presented here allows to illustrate the large diversity of issues involved in the American mobile nuclear reactor programme, ranging from economic considerations, over military strategy, to environmental and health concerns. During several decades, mobile nuclear power reactors were considered a cheap and clean solution, yet as this essay shows, history proved otherwise. None of the economic targets were met and in the case of the Antarctic reactor, repeated failures and even radioactive leakages lead finally to the shutdown of the whole programme. ; Même si l'énergie nucléaire joue un rôle important et controversé dans l'histoire polaire, son usage et son mésusage ont reçu très peu d'attention de la part des historiens. Les réacteurs nucléaires mobiles en particulier, tels qu'ils ont été mis en oeuvre sur le continent antarctique, ont occupé une fonction cruciale dans la conquête des régions polaires. Le cas antarctique présenté ici permet d'illustrer la grande diversité des éléments invoqués dans le programme étatsunien de réacteurs nucléaires mobiles, allant de considérations économiques, en passant par la stratégie militaire, à des inquiétudes environnementales et de santé publique. Pendant plusieurs décennies, les réacteurs nucléaires mobiles ont été considérés une solution peu couteuse et propre, mais comme nous allons arguer ci-dessous, l'histoire en a voulu autrement. Aucun des objectifs économiques ne fut atteint et dans le cas du réacteur en Antarctique, de nombreuses coupures et même des fuites radioactives ont amené enfin à l'abandon du programme.
This thesis aims at highlighting the ethical, metaphysical and aesthetic questions that arise in the mature works of the Austrian author Hugo von Hofmannsthal. After having dealt with Hofmannsthal's original dilemma between opposing conceptions of the world and of his own existence, this work considers the two versions of The Woman without a Shadow. This opus is the first expression at maturity of his aesthetic whose underlying metaphysical foundation it enlightens.The experience of First World War, subject of our third chapter, compelled Hofmannsthal to widen the scope of his thoughts. His later plays illustrate which ethical conducts should rule individuals in a given society as well as between the peoples in Europe. The Salzburg Great World Theaterwhich is the focus of our fourth chapter, sets the pattern of his social ethics inspired by the principles of the social doctrine of the Church. As for The Tower, a tragedy which we will deeply analyse in our fifth chapter, it sketches his ethics for political action. The purpose of this play is indeed to advocate peace in Europe while helping nations to achieve higher standard of Humanity. ; L'objet de cette thèse est de mettre en lumière les interrogations éthiques, métaphysiques et esthétiques qui accompagnent la production des œuvres de maturité de !'écrivain autrichien Hugo von Hofmannsthal. Après avoir rappelé ses hésitations initiales entre des conceptions du monde et de l'existence distinctes, ce travail envisage les deux versions de la Femme sans ombre. Cette œuvre offre une première expression de son esthétique de maturité dont elle éclaire aussi les fondements métaphysiques. L'expérience de la Première Guerre mondiale, analysée dans le troisième chapitre, conduit Hofmannsthal à élargir le champ de ses réflexions. Son œuvre dramatique devient l'illustration des principes éthiques devant régler les échanges entre les membres d'une même société ainsi qu'entre les peuples d'Europe.

Although the term "cluster" has been widely used in academic and political circles since the 1990s, we will see that the cultural cluster takes different forms. We will try to show through this analysis, what are the specificities of a particular type of cluster: metropolitan cultural clusters. Their edification is part of a dual desire to build new political objects in a new way. These clusters can be considered new political objects by their hybrid nature. They depend on both public policies and urban, economic and cultural dynamics.To better understand our research subject we will adopt a multidisciplinary scientific approach to be at the intersection of these three perspectives. This is the originality of our approach. In short, it is a question of seeing how the evolution of these clusters is structured through the relationships between actors, of clarifying the logics behind these projects, the choices, the conflicts and the changes of position of the actors. Less sectoral and more territorialized, metropolitan cultural clusters are based on projects where processes matter more than results. These processes will be the core of our analysis and we will seek to understand their dynamics. The "new way of doing things" directly echoes governance. These projects defend themselves from adopting a top down approach, decided «from the top to the bottom» and assume a development that would be organic, whose strategies would not be frozen and would evolve according to opportunities. Despite these wishes, the cultural clusters we are studying bear the stigma of the past. The term cluster is inherited from industrial policies. The coordination methods of the players in these clusters seem to be fixed in old models and much less open than they suggest. Starting from case studies, and thanks to an international comparative analysis, we will highlight the complexity behind this cultural cluster term. Through a longitudinal approach we will retrace the evolution of their objectives, whose factors we will seek to identify. ...

Depuis les années 60, le rock fait partie, avec d'autres cultures populaires comme la Science-fiction, des nouvelles sources d'inspiration et de réflexions que détournent les artistes plasticiens. Dérivé du blues et de la country, musiques rurales américaines, le rock qui apparaît à la fin des fifties se profile comme une culture typiquement adolescente dont l'histoire oscille entre divertissement industriel et révolte suburbaine. Célébrée avec nostalgie ou parodiée avec virulence, sa religion ? hante, depuis le Pop Art, tout un pan de l'art contemporain de ses distorsions électriques et refrains diaboliques. Associé à l'art, il élargi le spectre d'une sensibilité désormais partagée : de la révolte politique à la crise identitaire en passant par le nihilisme artistique. 0Exhibition: Mac's, Grand-Hornu, Belgium (23.10.2016-22.01.2017)
