Les déformations rachidiennes se réfèrent aux patients avec une courbure anormal de la colonne vertébrale qui ont terminé leur croissance. Par leur prévalence, leur impact clinique, et le taux relativement élevé d'échecs chirurgicaux, elles représentent un défi thérapeutique. La recherche a permis de démontrer que la préservation ou la restauration de l'alignement, sont des éléments clé du traitement chirurgical. L'objectif de cette thèse était d'analyser le traitement des patients avec DR, avec un intérêt particulier pour la restauration de l'alignement sagittal et l'évaluation musculaire. Fondé sur une analyse rétrospective d'une base de données multicentriques, les deux premiers articles présentent une évaluation du traitement chirurgical en termes d'efficacité clinique et de réalignement radiographique. Les écarts entre la planification préopératoire et l'exécution opérationnelle ont aussi été étudiés avec une collecte de données prospectives, et ont mis en évidence la nécessité de mieux comprendre le rôle des muscles dans le maintien de la posture. Par conséquent, deux protocoles pour la caractérisation des principaux muscles impliqués dans l'alignement sagittal ont été validés. Les deux méthodes sont basées sur la segmentation manuelle d'acquisition IRM spécifique (méthode de Dixon) afin d'obtenir l'infiltration graisseuse en plus du volume musculaire. Une des méthodes permet d'obtenir la reconstruction 3D des muscles et donc de générer des modèles musculo-squelettiques personnalisés. L'autre ouvre la voie à une pratique clinique car nécessite seulement la segmentation de quatre coupes pour obtenir une évaluation des principaux groupes musculaires. Enfin, à partir de la première méthode, le système musculaire de patients avec DR a été décrit. / Adult spinal deformity(ASD) refers to abnormal curvatures of the spine in patients who have completed their growth. Due to its prevalence, clinical impact, and the relatively high rate of surgical failures, they represent a therapeutic challenge. Research has been able to demonstrate that the preservation or the restoration of the sagittal alignment, are key objectives of surgical treatment. The objective of this thesis is to analyze the treatment of ASD patients, with particular interest in restoration of sagittal alignment and to develop tools to assess the spino-pelvic musculature of ASD patients. Based on an analysis of a multicenter database, the first two articles present an evaluation of the surgical treatment in term of clinical effectiveness and radiographic realignment. In addition, the discrepancies between surgical preoperative planning and operative execution have been studied with a prospective data collection, and have highlighted the necessity to understand better the role of the muscles in the maintaining of the posture. Therefore two methods for the characterization of the muscles involved in the sagittal alignment have been validated. Both methods are based on manual segmentation of specific MRI acquisition (Dixon methods) in order to obtain precise fat infiltration quantification in addition to muscular volume. One method permits to obtain 3D reconstruction able to generate patient–specific musculoskeletal model. The other one open the path to a clinical purpose, because necessitate only segmentation of four slices to obtain an relevant evaluation of the muscular system. Finally, thanks to the first protocol the muscular system of ASD patients have been described.

As eleições presidenciais são a principal competição do sistema político brasileiro. Há duas proposições dominantes que perpassam as análises da literatura sobre sua natureza e dinâmica: o Programa Bolsa-Família (PBF) é considerado central e determinante para os resultados eleitorais e teria contribuído, no pleito de 2006, para conformar um realinhamento das bases eleitorais do PT, único partido competitivo em todas as eleições. O programa social é considerado fundamental para explicar a força deste partido no Nordeste e entre eleitores pobres. Nesta tese, por meio de replicação de modelos da literatura e da análise de modelos originais a partir de survey, de dados agregados ao nível municipal e ao nível das urnas, e com a aplicação de diferentes metodologias, procuro debater essas hipóteses, apontando inconsistências e deficiências teóricas, metodológicas e empíricas. Os resultados apontam para diagnósticos alternativos às teses vigentes. Primeiro, procuro argumentar que a relação entre as mudanças eleitorais de 2006 e os perfis sociais dos eleitores ocorrem de forma heterogênea pelas regiões e tipos de localidade, e que, após mensuração adequada, essas flutuações são melhor compreendidas como movimentações de eleitores voláteis, e não como realinhamento de bases eleitorais. Além disso, contrariamente às análises correntes, ressalto que a investigação sobre o efeito eleitoral do PBF não deve ser restrita aos seus beneficiários e nem se pode inferir sua importância no resultado eleitoral a partir da sua distribuição regional. Antes, as análises conduzidas nesta tese revelam que o impacto do programa social para as decisões eleitorais foi mais importante no Sudeste que no Nordeste, e não se restringe a eleitores diretamente beneficiários do programa. Por fim, mostro que, após enquadramento adequado, é possível dizer que o impacto do PBF para o resultado eleitoral não foi tão pronunciado ou determinante dos resultados eleitorais. Do ponto de vista mais geral, meu argumento ressalta que as bases eleitorais de longo-prazo dos partidos influenciam os resultados presentes, matizando a importância das mudanças ocorridas em 2006, e sublinha que o efeito do PBF, assim como de qualquer outra política pública com peso político-eleitoral, não pode ser tomado isoladamente, fora do contexto da disputa eleitoral e política. / The presidential elections are the main competition of the Brazilian political system. The current literature on the subject pointed out two thesis about the nature and dynamic of presidential elections: The Bolsa-Família (PBF) conditional cash transfer program is considered to be central and determinant to the electoral results and in 2006 would have contributed to realign the electoral bases of PT, the only party competitive in all elections. The policy is considered to be fundamental to explain the strength of the party on Northeast among poor electors. On this dissertation I examine these hypothesis and debate the theoretical, methodological and empirical inconsistences and deficiencies of the current literature. In order to do so, I replicate models, analyze novel models looking at surveys and aggregate data on the municipal level and on ballot level, among other methods. The results highlight conclusions different from the standing literature. First, I argue that the correlation between the electoral changes of 2006 and the social profile of electors occur heterogeneously over different regions and localities. If the proper measure is applied, these variations are better understood as a movement of volatile electors and not as realignment of electoral bases. Moreover, contrary to the current literature, I emphasize that the investigation over the electoral effect of the PBF shouldn\'t be restricted to its beneficiaries and neither that it is possible to infer its importance on the electoral result based on its regional distribution. Contrarily, based on the data we gathered, the impact of the PBF to the electoral results was more important on the Southeast than on the Northeast and it is not restricted to electors directly beneficed by the program. Still, I argue that if the adequate framework is adopted, it is possible to say that the impact of the PBF on the electoral results wasn\'t very strong or determinant to the electoral result. I conclude that the parties\' long term electoral bases influence on present results, minimizing the fluctuations that occurred in 2006. As it happens with all the policies with high potential to impact on voters decisions, the effect of the PBF cannot be analyzed separately, it has to be considered inside the context of the electoral and political dispute.

Rapid changes in the economic and world order have made it imperative for university libraries to make a paradigm shift from prestige collection building to a marketing philosophy as their strategic directive. This philosophy would direct university libraries towards decision making around customers' real needs and preferences, aligning organisational competencies and processes with these needs, resulting in more effective service delivery. Changes in the world order, economics and marketing as a philosophy are presented on a time line, revealing the influence developments in technology and the Internet have brought about. Various views on the influence of these changes in the world order are presented. Marketing in service organisations is encapsulated in a service marketing triangle. Competitive advantage for the university library should be achieved if the internal processes of the library are analysed in the context of a value chain. A proposed marketing model has been presented to direct strategic thinking in the university library. / Information Science / M. Inf.

Conservation of intertidal habitats in the UK is vital in order to continue to support nationally and internationally important populations of non-breeding waterbirds. Historic reclamation for agriculture and industry has resulted in the loss and degradation of large areas of these intertidal habitats in estuaries and they continue to be threatened by sea-level rise. Managed realignment is one method which is increasingly being used to restore intertidal habitats. As managed realignment is a relatively new restoration technique, the extent to which knowledge of the biology of estuaries is applicable to managed realignment sites is unclear. Habitat restoration is often unsuccessful or incomplete, so a detailed knowledge of both the natural system and the characteristics of restored systems will usually be necessary to recreate fully-functional estuarine habitats. This thesis focuses on Nigg Bay Managed Realignment Site (Nigg Bay MRS), the first managed realignment site in Scotland, and follows the first four years of ecological development to gain an understanding of how breached realignment can be used to restore intertidal habitats to support non-breeding waterbirds. This thesis has six major aims: (i) to describe the development of saltmarsh, (ii) to describe the development of intertidal flat, (iii) to describe the colonisation by non-breeding waterbirds (iv) to determine how tidal cycle and weather affect patterns of waterbird use, (v) to determine which factors affect the spatial distribution of waders and finally (vi) to determine the patterns of use by individual birds. Four summers after the re-establishment of tidal conditions, almost all of the saltmarsh species recorded on the nearby saltmarsh had colonised Nigg Bay MRS, although recognisable communities had yet to establish. Three winters after the re- establishment of tidal conditions in Nigg Bay MRS, the sediments had a significantly smaller particle size and higher organic matter content compared to the fine sands of the adjacent intertidal flats. The intertidal invertebrate community also differed from the adjacent intertidal flats. Nigg Bay MRS attracted large numbers of non-breeding waterbirds and supported each of the most common wader and wildfowl species present in the wider estuary. Nigg Bay MRS performs a number of important functions for non-breeding waterbirds by: (i) providing a foraging and resting habitat when the tide is absent and intertidal sediments in Nigg Bay are exposed; (ii) providing a foraging resource as the tide passes over the intertidal sediments within the site once the intertidal flats in Nigg Bay are inundated; and (iii) providing a high tide roosting site. On days with low temperatures and high wind speeds, more waterbirds use Nigg Bay MRS, suggesting that it is likely to be providing sheltering benefits. Nigg Bay MRS also provides top-up feeding habitat. The factors that often influence the spatial distributions of waders in estuaries appear to be operating within Nigg Bay MRS. Wader densities are greater on the intertidal flats when they are accessible than on the saltmarsh. Wader densities are also greatest close to creeks and drainage channels, possibly due to higher invertebrate densities, more accessible prey or sheltering benefits. Colour-ringing and radio-tracking of Common Redshank established that Nigg Bay MRS has a subset of regular users, including both adults and juveniles, and the wader assemblage at night may differ from the assemblage during the day. These findings are discussed in terms of the implications for locating, designing and managing future managed realignment projects.

L’étude chronologique et thématique des votes frontistes lors des scrutins nationaux et intermédiaires dans quarante-six petites communes rurales de l’Ouest héraultais entre 1984 et 2014, complétée par un travail monographique sur cinq d’entre-elles a permis de mettre en évidence l’importance relativement restreinte de ces votes jusqu’en 2011, hormis dans un « noyau dur » de communes, précocement constitué, mais de faible importance démographique. L’arrivée de Marine Le Pen à la présidence du Front national coïncide avec une période de croissance continue des votes frontistes et avec leur généralisation à la quasi-totalité des communes ciblées, ce qui serait en faveur d’un réalignement électoral. Les transformations structurelles des communes, marquées par la baisse rapide du secteur agricole et la montée du salariat en lien avec le secteur des services, apparaissent comme l’un des facteurs favorables de cette croissance. Le FN, n’étant pas à ce jour un parti de gouvernement pour diverses raisons dont les principales sont le mode de scrutin uninominal à deux tours et le manque d’alliance, les succès électoraux qu’il obtient sont très largement basés sur la confiance dans des promesses. Cette donnée rend difficile de prévoir la pérennité à long terme d’une implantation, d’autant que les communes étudiées font actuellement l’objet de transformations administratives importantes avec le risque pour certaines de disparaître. / The chronological and thematic study of the votes supporting the National Front party during the national and intermediate ballots in forty six small rural districts on the west of the department of the Hérault, between 1984 and 2014, completed by a monographic work on five of them allowed to highlight the importance relatively restricted by these votes until 2011, except in a "hard core" of municipalities prematurely constituted but of weak demographic importance. The arrival of Marine Le Pen to the chair of the National Front coincides with a period of continuous growth of the votes supporting the National Front party and their generalization in almost all of the targeted municipalities which plead for an effective electoral realignment. The structural transformations of the municipalities, characterized by the fast reduction in the farming sector and the rise of the wage-earning in connection with the service sector, appear as one of the favorable factors of this growth. The FN, not being this day a party of government for various reasons, whose main clauses are the uninominal voting system in two ballots and the lack of alliances, the electoral successes which it obtains are very widely based on the confidence in promises. This fact makes difficult to plan the long-term sustainability of a setting-up, especially since studied districts even are at present the object of important administrative transformations with the risk for some to disappear. / El estudio cronológico y temático de los votos frontistes durante las elecciones nacionales y locales en cuarenta y seis pequeños municipios rurales del oeste del departamento de Hérault entre 1984 y 2014, completado con un trabajo monográfico sobre cinco de ellos, ha permitido poner de manifestio la importancia relativamente pequeña de estos votos hasta 2011, exceptó en un núcleo de comunas constituido temprana pero de menor importancia demográfica. Cón la llegada de Marine Le Pen a la presidencia del Fronte Nacional coincide un periodó de continuo crecimiento de los votos frontistes y de su generalización a la práctica totalidad de los municipios focales, lo que aboga por un reajuste electoral. Las transformaciónes estructurales de las comunas se caracterizan por el rapido descenso del sector agricola y el aumento del asalariado relacionado con los servicios, que aparecen comó unos de los factores favorables de este crecimiento. Hasta ahora, el FN no estando un partido de gobierno por diversas razones, cuyas principales son el modo de escrutinio uninominal a dos vueltas y la falta de alianza, sus éxitos electorales se debe en gran medida por la confianza en suas promesas. Este echo produce dificultades para pronosticar la viabilitad a largo plazo de su implantación. Tanto màs cuanto que los municipios estudiados estan actualmente objeto de importantes transformaciones administrativas, con un riesgo en algunos casos de desaparecer.
