A Serra Gaúcha é considerada uma área densa de vocações turística, histórico-cultural, enogastronômica e industrial. Entendendo Serra Gaúcha‟ como demarcação de determinados setores regionais, parte-se do princípio de que se constitua, segundo processos de conceptualização, como uma categoria conceitual. Assim, com o aparato da Linguística Cognitiva, analisa-se como essa categoria SERRA GAÚCHA é demarcada no discurso turístico publicitário. Há diversas formas de demarcação: regiões culturais (em função de traços da imigração), geografia, setor turístico (divisão em microrregiões turísticas conforme Secretaria do Turismo do Estado), agrupamentos em função de interesses econômicos (setor moveleiro, vinícola e metalúrgico). Nesta dissertação, investigam-se as diferentes formas de categorizar a região nomeada Serra Gaúcha‟ um topônimo pela perspectiva do setor turístico, com o objetivo de identificar os modelos cognitivos e culturais subjacentes aos discursos que constituem o corpus de estudo, composto de material de divulgação turística da Serra Gaúcha. Verifica-se que as demarcações regionais no discurso turístico publicitário fazem uso de modelos metafóricos e metonímicos, que geram efeitos de prototipicidade. Especificamente, SERRA GAÚCHA é conceptualizada, metonimicamente, por referência aos produtos gerados na região, demarcando-a como mercados potenciais de consumo. As características (metonimizadas ou metaforizadas) têm o papel de atrair o turista para um mercado de opções de consumo: natureza, patrimônio cultural, gastronomia, produtos "típicos", entre outros. / Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-06-05T17:02:55Z No. of bitstreams: 1 Dissertacao Garine Andrea Keller.pdf: 6628976 bytes, checksum: 553e0efb515deb17c15973bad00c07d7 (MD5) / Made available in DSpace on 2014-06-05T17:02:55Z (GMT).

Understanding "Serra Gaúcha" as the demarcation of certain regional areas, we start from the principle that it constitutes, according to a conceptualization process, as a conceptual category. Through means of Cognitive Linguistics, we analyze how the category SERRA GAUCHA is constructed on tourist advertising discourse. There are several forms of demarcation: cultural regions (due immigration traces), geography, tourism industry (division in micro tourist region following State Secretariat of Tourism) and sectorial groups of economic interests (furniture, metallurgical and wine). In this dissertation, we investigated different ways of categorizing the region named "Serra Gaúcha" a toponym from tourism sector perspective. We look forward to identify cognitive and cultural models underlying the discourses that constitute the corpus of study, compound of tourism advertising material of the Serra Gaúcha . It appears that the regional demarcations in tourist advertising discourse use metaphoric and metonymic models, which generate effects of prototypically. Specifically, Serra Gaúcha is conceptualized, metonymically, by reference to the products generated in the region, demarcating it as a potential consumer markets. Characteristics (metonymically or metaphorically) have a role in attracting tourists to a market of consumer choices: nature, cultural patrimony, gastronomy, typical products, among others.

La dynamique sédimentaire estuarienne joue un rôle très important pour la qualité de l'eau, les écosystèmes et la navigation. Les estuaires macrotidaux comme la Gironde se caractérisent par la formation de régions très chargées en matière en suspension (MES), appelées zones de turbidité maximale (ZTM), qui influencent le transport et le dépôt des sédiments fins, l'envasement des chenaux, la consommation d'oxygène dissous et le devenir des polluants. L'objectif de ce travail est de comprendre la dynamique hydro-sédimentaire, particulièrement de la ZTM, dans la section fluviale, encore peu étudié, de l'estuaire de la Gironde en lien avec les facteurs de forçage environnementaux et les perturbations du système (changements hydrologiques et morphologiques naturels et anthropiques). La méthodologie de ce travail est basée sur l'analyse de 10 années de données continues de turbidité enregistrées par le réseau de surveillance MAGEST. L'exploitation de telles séries de données, assez novatrice dans les estuaires, a notamment impliqué le développement d'une méthode d'analyse basée sur la combinaison de plusieurs méthodes spectrales. Cette approche est complétée par l'analyse des profils de turbidité et de vitesse de courant lors de cycles de marée, l'analyse de séries temporelles historiques de marée et l'exploitation d'un modèle semi-analytique 2DV. La dynamique sédimentaire de l'estuaire fluvial est d'abord détaillée à toutes les échelles de temps représentatives. A l'échelle de temps intratidale, la distribution verticale des MES et des courants, en deux points d'une même section transversale, a permis de détailler les mécanismes de transport sédimentaire. Les flux particulaires résiduels (totaux, advection, pompage tidal) ainsi estimés pour plusieurs conditions hydrologiques, démontrent le contrôle du pompage tidal sur les flux de MES lors de l'étiage. A l'échelle de temps subtidale, la réponse de la ZTM aux fluctuations hydrologiques (crues, périodes d'augmentation ou diminution continue du débit, variabilité inter-anuelle) est analysée. Ceci a permis de définir plusieurs indicateurs hydrologiques des caractéristiques de la ZTM, qui suggèrent l'intensification de la ZTM au cours des dernières décennies en lien avec la diminution des débit. La contribution relative des facteurs de forçage à la variabilité de la turbidité a été quantifiée pour différentes régions estuariennes et échelles de temps (saisonnière et plurianuelle). L'application de la méthodologique développée à l'estuaire de la Loire, qui dispose de séries de données similaires (réseau SYVEL), a permis de généraliser ces résultats. Enfin, l'effet des changements pluri-décennaux hydrologiques et morphologiques sur la propagation de la marée et la dynamique sédimentaire est détaillé dans la Garonne tidale. Il ressort une amplification du marnage et de la asymétrie de la marée au cours des six dernières décennies, principalement liée aux changements morphologiques naturels dans la Gironde en aval, les extractions de granulat et le changement de régime hydrologique. L'implémentation d'un modèle semi-analytique a permis de vérifier ces résultats et d'analyser leurs implications sur les concentrations de MES et la limite amont de la ZTM. / Estuarine suspended sediment dynamics play an important role in water quality, ecosystems and navigation. The formation of regions of high suspended sediments (SS) concentrations, called turbidity maximum zones (TMZ), is a characteristic feature of macrotidal estuaries, such as the Gironde. The TMZ influences the transport and deposition of fine sediments, channel siltation, oxygen conditions and the particulate transport of pollutants. This work aims to understand the hydro-sedimentary dynamics of the fluvial Gironde estuary, still poorly studied, in relation with environmental forcings and system perturbations (natural and anthropic hydrological and morphological changes). The methodology of this work is based on the analysis of the 10-years continuous time series of turbidity recorded by the MAGEST monitoring network. The exploitation of such time series, quite innovative in estuaries, required the development of an analysis method based on the combination of spectral techniques. This approach is completed by the analysis of turbidity and current velocity profiles over tidal cycles, the analysis of historical tide time series, and the exploitation of a 2DV semi-analytical model. First, SS dynamics of the fluvial Gironde is detailed at all representative time scales. At the intratidal time scale, the mechanisms of SS transport were described from the vertical depth of SSC and current velocities at two points of the same section. Residual fluxes (total, advective and tidal pumping), estimated for different hydrological conditions, demonstrated the control of tidal pumping on SS fluxes during periods of low river flow. At the subtidal time scale, the TMZ response to hydrological fluctuations (floods, periods of continuous river flow increase and decrease, interannual changes) was analyzed. Hydrological indicators of the TMZ features were thus defined, which suggest the TMZ intensification over the last decades in relation to the river flow decrease. The relative contributions of environmental forcings to the turbidity variability were quantified for different estuarine regions and time scales (seasonal and multiannual). The application of the same methodology to the Loire estuary, which counts on equivalent time series (SYVEL network), allowed the generalization of these results. Finally, the impact of pluri-decades hydrological and morphological changes on tidal propagation and suspended sediments dynamics is detailed in the tidal Garonne. Both tidal range and asymmetry appear to be amplified over the last six decades, mainly due to natural changes of the down Gironde, gravel extraction in the tidal Garonne and hydrological regime shifts. The implementation of an idealized model allowed verifying such results and analyzing their implications for SS concentrations and the upper TMZ limit.
