Cette recherche tente de mettre en évidence les mécanismes d’émergence de la danse contemporaine en France entre 1968 et 1981. Animés par un désir émancipateur de vivre et de danser particulièrement intense dans l’après Mai-68, les danseurs mais aussi journalistes, administrateurs ont produit des micropolitiques au travers desquelles leurs actions collectives et militantes, leurs désirs de pratiques et de danse ont permis de sédimenter, sans pour autant défaire les tensions et la contradictions visibles dès les années 1950, le champ chorégraphique contemporain. Avant d’aborder Mai 68 dans notre première partie, nous dressons un état des lieux du champ chorégraphique dans les années 1950 et 1960 afin de comprendre les conditions d’apparition de cette communauté encore fragile, confrontée à une bataille autour de la notion de modernité entre les tenants d’un héritage « classique » et ceux d’un héritage « moderne ». Si Mai 68 est ensuite envisagé comme un moment politique pour la danse, ses effets « culturels » s’inscrivent tout au long des années 1970. D’abord, ils rendent possible l’accueil des modernités venues des Etats-Unis. Puis, ils favorisent l’installation de modes de production et d’organisation autogérés et collectifs ainsi que des modes de militance en faveur de l’amélioration des conditions de vie et de création. À bien des égards, cette organisation du champ chorégraphique, par les marges et les « forces discrètes », a contribué à ce que l’on a appelé « l’explosion de la Nouvelle danse française » des années 1980. / This research tries to place in a prominent position the mechanisms of emergence of the contemporary dance in France between 1968 and 1981. Livened up by a desire emancipator to live and to dance particularly intense in the after 1968, the dancers but also journalists, administrators produced micropolitics through which their collective and militant actions, their desires of practices and dance allowed to sediment, without undoing the tension and visible contradictions from the 1950s, the contemporary choreograpic field. Before enter upon 1968 on our first part, we draw up an inventory of the choreographic field in the 1950s and 1960s to understand the condition of appearance of this still fragile community, confronted with a battle around the notion of modernity between the upholders of a « classic » legacy and those of a « modern » legacy. If 1968 is then envisaged as a political moment for the dance, its « cultural » effects join troughout 1970s. At first, they make possible the reception of the modernities come from the United States. Then, they favor the installation of self-managed and collective modes of production and organization as well as modes of militance in favour of the provement of the conditions of life and creation. In some respects, this organization of the choreographic field, by the margins et the « discreet strengths », contributed to what we called « the explosion of the New French dance » in the 1980s.

Orthogonal Frequency-Division Multiplexing (OFDM) has been proved to be a promising technology that enables the transmission of higher data rate. Multicarrier Code-Division Multiple Access (MC-CDMA) is a transmission technique which combines the advantages of both OFDM and Code-Division Multiplexing Access (CDMA), so as to allow high transmission rates over severe time-dispersive multi-path channels without the need of a complex receiver implementation. Also MC-CDMA exploits frequency diversity via the different subcarriers, and therefore allows the high code rates systems to achieve good Bit Error Rate (BER) performances. Furthermore, the spreading in the frequency domain makes the time synchronization requirement much lower than traditional direct sequence CDMA schemes. There are still some problems when we use MC-CDMA. One is the high Peak-to-Average Power Ratio (PAPR) of the transmit signal. High PAPR leads to nonlinear distortion of the amplifier and results in inter-carrier self-interference plus out-of-band radiation. On the other hand, suppressing the Multiple Access Interference (MAI) is another crucial problem in the MC-CDMA system. Imperfect cross-correlation characteristics of the spreading codes and the multipath fading destroy the orthogonality among the users, and then cause MAI, which produces serious BER degradation in the system. Moreover, in uplink system the received signals at a base station are always asynchronous. This also destroys the orthogonality among the users, and hence, generates MAI which degrades the system performance. Besides those two problems, the interference should always be considered seriously for any communication system. In this dissertation, we design a novel MC-CDMA system, which has low PAPR and mitigated MAI. The new Semi-blind channel estimation and multi-user data detection based on Parallel Interference Cancellation (PIC) have been applied in the system. The Low Density Parity Codes (LDPC) has also been introduced into the system to improve the performance. Different interference models are analyzed in multi-carrier communication systems and then the effective interference suppression for MC-CDMA systems is employed in this dissertation. The experimental results indicate that our system not only significantly reduces the PAPR and MAI but also effectively suppresses the outside interference with low complexity. Finally, we present a practical cognitive application of the proposed system over the software defined radio platform.

Cette thèse de doctorat est consacrée à Guy Hocquenghem (1946-1988), militant « gauchiste » dans les années 1968, figure du Front homosexuel d'action révolutionnaire fondé à Paris en 1971, enseignant à l'université de Vincennes, journaliste à Libération et écrivain, mort du Sida. Discutant plusieurs contributions des sciences sociales sur la biographie, cette thèse est construite comme l'analyse d'une « trajectoire », notion empruntée à Pierre Bourdieu. À partir d'un important travail d'archives et de 130 entretiens semi-directifs, il s'est agi, en retraçant le parcours d'Hocquenghem, de restituer des débats majeurs qu'il a traversés et dont il a été un acteur de premier plan, et de retracer un certain nombre de champs, au sens d'espaces autonomes de la vie sociale, et les logiques qui les animaient. En particulier, cette thèse de doctorat s'intéresse aux mobilisations politiques et aux mouvements sociaux de l'après-1968 en France, en Europe et aux États-Unis, et étudie plusieurs champs recoupant le mouvement homosexuel radical, les débats politiques qui traversent le « gauchisme » et la contre-culture, les intellectuels de la gauche radicale (Jean-Paul Sartre, Michel Foucault, Gilles Deleuze et Félix Guattari, Louis Althusser, Jacques Rancière, etc.), l'enseignement de la philosophie, les discussions théoriques sur la sexualité et l'enfance, la contestation du marxisme, les relectures critiques de la psychanalyse ou encore la littérature du Sida / ...

Der 35. Mai, Erich Kastner's least popular young people's book, has received only little attention by critical reviewers, and is seldom included in comparative studies that deal with the body of his early young people's literature. Due to the existence of only a few critical secondary sources and convincing studies showing the works unpopularity, this thesis wants to add new critical insights and give reasons for the failure of this particular book. Secondly, this examination will question the rather uncritically and quickly affixed label young people's literature that haunts Der 35. Mai until today. This study reviews Kastner's biographic background until Der 35. Mai publishing date, summarizes its content, examines important social issues of the Weimar Republic, establishes national and international intertextuality highlighting Kastner' s intent and sources, and finally speculates on the author's intentions and hopes for the book. This work wants to rediscover Der 35. Mai as valuable social criticism that fell victim to its historical circumstances. Many textual examples will show that the social issues addressed require a mature, adult audience, and rather than calling this work an artistic failure, this analysis attributes Kastner' s mixing of social criticism and fantastic story line to his avant garde insights and pioneering intents for the German young people's literature genre. A combination of Kastner' s biography, close reading, and intertextual analysis reveals that Erich Kastner wrote a mixed-genre book, combining social criticism and fanciful narrative in a Neue Sachlichkeit language. Der 35. Mai is understood as the author's pedagogical intent to have parent and child interact and resolve intergenerational conflicts through enlightened discussions. By using the young people's literature genre as a vehicle, Kastner possibly tried to circumvent later censoring. Kastner' s proposed dialogue for conflict resolution came, nevertheless, too late in 1932 and could not fully spread its enlightening message. Der 35. Mai had missed its historical moment and has since been forgotten as a sincere and clever attempt to help change the course of history.
