La Otredad Indígena en el Panorama Sociocultural Mexicano del Siglo XX

Maldonado, Maritza, Maldonado, Maritza January 2017 (has links)
Tomando en cuenta la naturaleza pluricultural y pluriétnica de la México, la presente tesis doctoral comienza por observar y analizar las maneras en que los medios de comunicación masiva tradicionalmente han contribuido a la distorsión y devaluación de las identidades de los indígenas mexicanos, así como a la fabricación de sus representaciones más caricaturescas en el México moderno. Arguyo que los medios de comunicación masiva han coadyuvado en la formación de tres construcciones socioculturales falsamente enraizadas en los pueblos indígenas de México. Ellos son el indio, el indio-campesino y el naco. Particularmente la cinematografía y la literatura han tenido un rol crítico en la tarea de insertar tales identidades artificiosas, genéricas e indiferenciadas en la cultura dominante mestiza mexicana, para ser absorbidas y reproducidas como constructos de identidad históricos profundamente asentados en el imaginario sociocultural colectivo de sus ciudadanos. Además de formas masivas más tradicionales como la cinematografía y la literatura, esta tesis doctoral examina la cultura popular y urbana, la música de rock en español, bogas y estilos de arrabal, dialectos urbanos y rurales y otros textos culturales como videos musicales, comics y sketches de comedia. Lo anterior permite una perspectiva alterna y más completa del proceso de creación, distorsión y tergiversación de dichas identidades indígenas ficticias arraigadas en la cultura dominante. En el primer capítulo establezco las formas en que el indio reemplazó la imagen del amerindio, y eventualmente la imagen del indígena mexicano contemporáneo. El segundo capítulo se centra en la imagen del campesino, así como en sus proximidades con el indio y la confusión identitaria que deriva de ellas. El resultado de tal amalgama es la construcción sociocultural del indio-campesino. El tercer capítulo analiza el constructo identitario del naco y sus vínculos con el indio, los cuales dirigen a la creación del naco-indio. Esta tesis doctoral argumenta que, debido a sus múltiples asociaciones con el indio, el indio-campesino ha sido incapaz de enunciar un discurso propio y de lograr autorrepresentarse. Sin embargo, el naco, a través de la música de rock en español y de los performances derivados de ella, pudo expresar su propio discurso y logró la autorrepresentación como una contracultura altamente efectiva y articulada durante las décadas de los ochenta y noventa.

Characterization of exoplanetary systems with the direct imaging technique : towards the first results of SPHERE at the Very Large Telescope / Caractérisation des systèmes d'exoplanètes par imagerie directe : vers les premiers résultats de SPHERE sur le Very Large Telescope

Zurlo, Alice 01 June 2015 (has links)
Aujourd’hui, plus de 1800 planètes qui orbitent autour d’étoiles en dehors du système solaire ont été découvertes. La plupart des planètes découvertes actuellement a été révélée grâce aux méthodes indirectes. Par contre, avec ce type de techniques, la caractérisation des planètes ne peut pas être complète si on n’utilise pas plusieurs techniques simultanément. Aussi, pour obtenir le spectre de la planète, il doit y avoir un transit et même dans ce cas là,le signal est très faible par rapport au signal de l’étoile. L’observation directe de ces objets, appellée imagerie directe, est maintenant possible grâce à des systèmes très avancés d’optique adaptative installés sur des télescopes de classe 8m. L’imagerie directe permet l’observation des planètes sufisamment lumineuses et éloignées de l’étoile principale en utilisant un masque qui cache la lumière de la dernière. Cette technique est donc efficace en particulier pour des systèmes jeunes et voisins car la luminosité intrinsèque de la planète diminue avec l’âge et la séparation réelle de la planète dépend de la distance du système. Dans le VLT au Paranal (Chili), deux instruments sont dédiés à ce type de recherche : NACO et SPHERE. SPHERE a vu sa première lumière en Mai 2014, et est maintenant prêt à commencer une enquête consacrée à la découverte de planètes autour de systèmes jeunes et voisins, NIRSUR. Cet instrument se compose de trois sous-systèmes : IRDIS, IFS et ZIMPOL. / In the year of the 20th anniversary of the discovery of the first extrasolar planet we can count more than 1800 companions found with different techniques. The majority of them are indirect methods that infer the presence of an orbiting body by observing the parent star (radial velocity, transits, astrometry). In this work we explore the technique that permits to directly observe planets and retrieve their spectra, under the conditions that they are bright and far enough from their host star. Direct imaging is a new technique became possible thanks to a new generation of extreme adaptive optics instruments mounted on 8m class telescopes. On the Very Large Telescope two instruments dedicated to the research for exoplanets with direct imaging are now operative: NACO and SPHERE. This thesis will describe the development and results of SPHERE from its predecessor NACO to its integration in laboratory and the final on sky results.

Authority control in an academic library consortium using a union catalogue maintained by a central office for authority control

Marais, Hester, 1961- 31 March 2004 (has links)
Authority control is the backbone of the library catalogue and therefore a critical library activity. Experienced staff create authority records to assist users in their quest for information. The focus of this study is on authority control as a means of co-operation in academic library consortia using a union catalogue maintained by a Central Office for Authority Control. Literature studies were conducted on three sub-problems: the development of academic library consortia in South Africa, and various forms, characteristics and functions of academic library consortia in general; the characteristics, principals and objectives of authority control; and the functions of union catalogues with special reference to the role of Z39.50 within virtual union catalogues. The conclusion was that existing and new authority records should be made available as widely as possible within consortia through a union catalogue. It is however a partial solution, because not all the libraries within the consortium have the expertise to create new authority records. Two empirical studies were conducted. A cost analysis was done to determine the cost of creating and changing authority records within academic library consortia in South Africa, in order to choose a system within which authority control can be performed effectively and speedily. Secondly, a questionnaire was sent to libraries in the United States to gather information on their experiences with regard to authority control, library co-operation in general, and virtual union catalogues. The United States was the natural choice because it could be regarded as the birthplace of modern library consortia. Inferences drawn from the information received was used to develop the structure and functions for a Central Office for Authority Control in academic library consortia in South Africa. It was found that authority control within an academic library consortium using a union catalogue could be conducted most cost-effectively and timeously through such a Central Office for Authority Control. The purpose of the Central Office would be to co-ordinate authority control within the consortium. Pooling available resources within the consortium would keep the cost of authority control as low as possible. Libraries with the required infrastructure and expertise would have the opportunity to create authority records on behalf of other libraries and be compensated for their services. Through such a Central Office more authority records created according to mutually accepted standards would be available for sharing within the consortium. / Information Science / D.Litt. et Phil.

Stratigraphy and Sedimentology of the Bisbee Group in the Whetstone Mountains, Pima and Cochise Counties, Southeastern Arizona

Archibald, Lawrence Eben January 1982 (has links)
The Aptian-Santonian(?) Bisbee Group in the Whetstone Mountains comprises 2375 m of clastic sedimentary rocks and limestones. The basal Glance Conglomerate unconformably overlies the Pennsylvanian-Permian Naco Group. It consists of limestone conglomerates which were deposited in proximal alluvial fan environments. The superadjacent Willow Canyon Formation contains finer grained rocks which were deposited in the distal portions of alluvial fans. The lacustrine limestones in the Apache Canyon Formation interfinger with and overlie these alluvial fan facies. The overlying Shellenberger Canyon Formation is composed mostly of terrigenous rocks derived from westerly terranes. This formation contains thick sequences of fluvio-deltaic facies as well as a thin interval of estuarine deposits which mark a northwestern extension of the marine transgression in the Bisbee -Chihuahua Embayment. The youngest formation (Upper Cretaceous?) in the Bisbee Group, the Turney Ranch Formation, consists of interbedded sandstones and marls which were deposited by fluvial and marine(?) processes.
