Dans quelle mesure l'évolution de Martin Heidegger le conduisant en 1933 à appeler à « l'anéantissement total » de l'ennemi intérieur peut-elle être comprise par la théorie de George Mosse de la « brutalisation » de la politique allemande après la Première Guerre mondiale ? Vétéran quoique n'ayant pas connu la première ligne, Heidegger fut en effet radicalisé par son expérience de l'armée, sans que c'en fût la seule cause : le « mythe de l'expérience de la guerre », diffusé par la culture du temps, de même que la paix brutale subie par l'Allemagne, jouèrent également un rôle significatif et conforme aux thèses de Mosse. Cela n'aurait pu avoir lieu sans les arrière-plans idéologiques critiques de Heidegger : d'abord un catholicisme intransigeant, puis les idéaux du Mouvement de jeunesse, enfin le nazisme.

A portrait of Martin Heidegger as a man and a philosopher In this biography of Martin Heidegger (1889-1976), now available in English, historian Guillaume Payen synthesizes the connections between the German philosopher's life and work. Critically, but without polemics, he creates a portrait of Heidegger in his time, using all available sources--lectures, letters, and the notorious "black notebooks." Payen chronicles Heidegger's "changing destinies": after the First World War, an uncompromising Catholicism gave way to a vigorous striving for a philosophical revolution--fertile ground for National Socialism. The book reflects a life of light and shadow. Heidegger was a great philosopher and teacher who cultivated friendships and love affairs with Jews but also was an anti-Semitic nationalist who lamented the "Judaization of German intellectual life"

Le plan câble vise à contrôler dans un réseau unique l'ensemble des formes modernes de la communication. La Direction Générale des Télécommunications est l'administration qui a conçu et fait aboutir le projet. Celui-ci s'insère dans le projet gouvernemental d'informatisation et de décentralisation et contribue aux objectifs de relance économique : il allie donc un programme industriel à un projet politique.
Le projet est issu en fait d'une équipe de prospective technologique qui a su profiter de l'alternance politique pour valoriser une logique sectorielle.

In order to recognize the importance of ozone (O3) in the troposphere and lower stratosphere in the tropics, a DIAL (differential absorption lidar) tropospheric O3 lidar system (LIO3TUR) was developed and installed at the Université de la Réunion campus site (close to the sea) on Reunion Island (southern tropics) in 1998. From 1998 to 2010, it acquired 427 O3 profiles from the low to the upper troposphere and has been central to several studies. In 2012, the system was moved up to the new Maïdo Observatory facility (2160-l. - metres above mean sea level) where it started operation in February 2013. The current system (LIO3T) configuration generates a 266 beam obtained with the fourth harmonic of a Nd:YAG laser sent into a Raman cell filled up with deuterium (using helium as buffer gas), generating the 289 and 316 beams to enable the use of the DIAL method for O3 profile measurements. The optimal range for the actual system is 6-19ga.m.s.l. depending on the instrumental and atmospheric conditions. For a 1gh integration time, vertical resolution varies from 0.7gkm at 6ga.m.s.l. to 1.3gkm at 19ga.m.s.l. and mean uncertainty within the 6-19gkm range is between 6 and 13g%. Comparisons with eight electrochemical concentration cell (ECC) sondes simultaneously launched from the Maïdo Observatory show good agreement between data sets with a 6.8g% mean absolute relative difference ( D ) between 6 and 17ga.m.s.l. (LIO3T lower than ECC). Comparisons with 37 ECC sondes launched from the nearby Gillot site during the daytime in a ±24gh window around lidar shooting result in a 9.4g% D between 6 and 19ga.m.s.l. (LIO3T lower than ECC). Comparisons with 11 ground-based Network for Detection of Atmospheric Composition Change (NDACC) Fourier transform infrared (FTIR) spectrometer measurements acquired during the daytime in a ±24gh window around lidar shooting show good agreement between data sets with a D of 11.8g% for the 8.5-16gkm partial column (LIO3T higher than FTIR), and comparisons with 39 simultaneous Infrared Atmospheric ...
