Décrivant l'ascension sociale d'un groupe de chevaliers valant par leur seule compétence, le "Poème du Cid" proclame le modèle d'une seigneurie personnelle destinée à corriger les effets néfastes d'un régime fondé essentiellement sur la 'nature'. Vouée à servir, quant à elle, les aspirations centralisatrices de la couronne, l'historiographie alphonsine tente d'imposer le modèle d'un ordre royal. Deux discours, donc, différents tant dans leur forme que dans les valeurs qu'ils véhiculent. Et pourtant, le "Poème du Cid" constitue l'essentiel du matériau narratif de l'"Histoire d'Espagne" pour l'histoire de Rodrigue Diaz et d'Alphonse VI. Quels furent, dans ces conditions, les procédés de transfert du discours épique au discours historiographique? Une étude minutieuse des similitudes que présentent les différentes versions de l'"Histoire d'Espagne" ("Chronique de vingt rois", "Version sancienne", "Chronique de Castille") permet de dégager les deux critères de sélection de l'information narrative: sa vraisemblance et sa fonctionnalité. Quatre opérations traduisent les mécanismes d'intégration de la geste à l'histoire: la segmentation, l'uniformisation, l'abréviation et surtout l'amplification. Sur ces remaniements repose l'essentiel du propos monarchique: réaliser la centralisation juridique et valoriser l'acte exemplaire de dépendance du sujet face au seigneur naturel. L'analyse des écarts entre les textes nous informe, à un autre niveau, de l'évolution du discours historiographique lui-même. Si le propos de l'historiographie reste inchangé, en revanche, la voix des destinateurs du récit s'exprime de façon plus personnelle. Ainsi, le texte accorde une large place à la noblesse chevaleresque, ces hommes désireux de gravir la hiérarchie des états en entrant au service du roi et qui, dans le dernier tiers du XIVe siècle, formeront les grandes Maisons Trastamare.

O movimento de ampliação das ações e dos recursos destinados à política brasileira de Cooperação Internacional para o Desenvolvimento deu-se acompanhado de uma construção discursiva do governo, a qual destaca princípios orientadores da atuação brasileira, como solidariedade, horizontalidade, atuação conforme demanda dos países parceiros, respeito à soberania, bem como ausência de condicionalidades e de interesses comerciais. Com base no referencial teórico-metodológico da Análise de Discurso Crítica – ADC, este trabalho parte da percepção de que existem disputas de poder travadas pelo Brasil no e pelo discurso sobre sua cooperação internacional. Desse modo, este trabalho tem como objetivo analisar a dimensão discursiva que integra a prática da cooperação internacional brasileira, inserida no contexto mais abrangente da Cooperação Internacional para o Desenvolvimento, explorando como mecanismos de poder operam no e pelo discurso brasileiro, bem como seus possíveis efeitos sobre a atuação do Brasil no cenário internacional de maneira mais ampla. ______________________________________________________________________________________________ ABSTRACT / Brazil’s engagement in International Cooperation for Development – ICD increased substantially between 2003-2010, specially with Latin American and African countries. The augmentation of actions related to and resources earmarked for Brazil’s International Cooperation for Development policy was followed by a governmental discursive formulation, which emphasizes the guiding principles of Brazilian ICD, such as solidarity, horizontality, acting according to demands from partner countries, respect for sovereignty, as well as absence of conditionality and commercial interests. Based on the Critical Discourse Analysis – CDA theoretical framework, this work is based on the assumption that there are power disputes waged by Brazil in and through its ICD discourse. Therefore, this work seeks to analyze the discursive dimension that integrates Brazil’s ICD practice, in the wider context of International Cooperation for Development, exploring how mechanisms of power operate in and through the Brazilian discourse and, more broadly, its possible effects on Brazil's international relations.

A Organização Mundial de Saúde tem hoje duas classificações de referência para a descrição dos estados de saúde: a CID-10 (Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde) e a CIF (Classificação Internacional de Funcionalidade, Incapacidade e Saúde). A utilização da CIF vem sendo aguardada com grande expectativa pelas organizações de pessoas com deficiências e instituições relacionadas. A falta de definição clara de “deficiência” ou “incapacidade” tem sido apontada como um impedimento para a promoção de saúde de pessoas com deficiência. Este trabalho tem como objetivo apresentar definições de deficiência, discutindo a utilização da CID-10 e da CIF e a contribuição da CIF para melhorar a compreensão sobre definições de deficiência a partir do conceito de funcionalidade e dos fatores contextuais. Foram revisados alguns diferentes conceitos/definições de deficiência, bem como publicações envolvendo a aplicação da CIF. São apresentadas algumas categorias de diagnósticos de estados de saúde da CID-10 hoje utilizadas em alguns sistemas, além de elementos da recém-apresentada CIF, que podem contribuir para diferentes campos de aplicabilidade no que diz respeito ao entendimento das definições de deficiência ou incapacidade. / The World Health Organization has nowadays two reference classifications for description of health conditions: ICD-10 (International Statistical Classification of Diseases and Health Related Problems) and ICF (International Classification of Functioning, Disability and Health). Organizations of people with disabilities and related institutions are waiting with high expectation for the ICF utilization. Lack of clear definition of “disability” is being pointed out as a deterrent for promoting the health of people with disabilities. The objective of this work is to evaluate definitions of disability, and discuss the use of ICD-10 and ICF and the contribution of ICF to improve understanding of definitions of disability through functioning and contextual factors. Some different definitions of disability have been reviewed, as well as publications involving ICF application. Diagnostic categories of health conditions of ICD-10 used in some systems are presented, as well as ICF components that could contribute for different fields of applicability regarding the understanding of definitions of disability.

The aim of this study was to determine which land line telephone and/or mobile/cellular telephone will enable an individual with a cochlear implant to achieve the best speech discrimination scores. Objective measurements and the subjective experience of the individual were used. The literature review provided an overview on the telephone abilities of individuals fitted with cochlear implants. In this study three factors, the quality of the telephone, the speaker's voice and different speech-coding strategies, were discussed and examined, in order to explore and explain the technical difficulties commonly experienced by this population regarding the successful use of a telephone. Data regarding various telephones and the influence different voice-types has on the telecommunication abilities were obtained through the execution of the methodology. Telephone abilities on five different telephones were assessed. Ten participants, four females and six males, fitted with the ESPrit 22, ESPrit 24 and ESPrit 3G Nucleus cochlear implants were used. The Central Institute for the Deaf (CID) open-set sentences were used and data was statistically analysed using a split plot design. Significant differences between different types of telephones were found. The results also suggested that different voice types have an impact on these individual's ability to use a telephone independently. Possible reasons such as different coding strategies, technical interference and quality of voices were discussed. Recommendations for developing rehabilitation programs, to obtain successful telephone competence for these individuals, were made and discussed. The study aimed to empower technologists working in this field to actively take note of the need for development and continuous research regarding various telephones. These telephones should enable more individuals fitted with cochlear implants to receive the maximum speech discrimination with the minimum interference. The findings of this study should encourage future research regarding this topic. A more extensive range of telephones should be used and compared to the findings in this study. / Dissertation (M (Communication Pathology))--University of Pretoria, 2006. / Speech-Language Pathology and Audiology / Unrestricted

This dissertation investigates non-covalent macromolecular chemistry using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) based techniques. The included studies reveal the impact of molecular structure on conformation and binding energetics. Supramolecules that might be too heavy to be dissociated in single collision-induced dissociation (CID) were dissociated using sustained off-resonance collision induced dissociation (SORI-CID) techniques. Relative binding energies and thresholds were evaluated for various macromolecular host-guest systems. Besides the non-covalent binding energies, conformation characterization was undertaken by a novel method to determine collision cross sectional areas using FTICR (CRAFTI, and multi-CRAFTI), initially developed by the Dearden lab. The systems chosen for further understanding of macromolecular interactions include calixarene-alkali metal complexes, cucurbit[5]uril-alkali halide complexes and cryptand-alkali metal complexes. The results were found to be consistent with expected behavior, and strongly correlated with predictions from computations. Size- and shape selectivity, as well as host-guest polarizability, are the main factors that govern the non-covalent macromolecular interactions that control complex conformation and dissociation. The results demonstrate the ability of FTICR to simultaneously determine binding energy, structure and conformation, which are the most important aspects for determination of comprehensive molecular characterization.

This dissertation expounds on the investigations of the structure and chemistry of peptides and supramolecular host-guest systems in the gas phase. These investigations used two different kinds of analytical instrument: Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) and ion mobility mass spectrometry (IM-MS, IMS). These investigations were complemented by chemical modeling. The FTICR was used to radially trap ions with its 4.7 T magnet, which allowed the ions to undergo sustained off-resonance irradiation collision-induced dissociation (SORI-CID). A subsequent event then measured the collision cross sections (σ) of the targeted precursor ion and one of the selected product ions. These experiments were repeated multiple times to measure σ for as many precursor/product pairs as possible. A similar kind of experiment was performed in the IM-MS instrument, through in-source collision-induced dissociation and size-based ion separation in the instrument’s mobility region. When the precursor/product σ ratios were compared, the values obtained by both methods were in good agreement with each other. Application of the FTICR-based technique to [2.2.2]-cryptand+Cs+ caused the externally bound Cs+ to migrate into the cryptand’s cavity. Further development of the FTICR-based technique allowed me to perform the post-SORI σ measurements in a time-resolved fashion. Data collected in this manner revealed that collisionally activated peptides refold over a 5 – 10 second timescale, as determined by their σ shrinking with time. These experiments allowed for observation of a peptide refolding. The IM-MS instrument was applied to a supramolecular chemistry problem surrounding cucurbit[7]uril (CB7), and its ability to bind two identical guests within its cavity. Literature precedent and conventional wisdom suggested that only one guest would bind within CB7’s cavity while the other guest would be bound externally. When ion mobility cross sections (Ω) were obtained for [CB7 + Guest2]2+ systems, it was discovered that both guests could be bound within CB7’s cavity. This was possible because the guests possessed the correct shape and chemistry to favor dispersive interactions between CB7’s cavity and the adjacent guest, and ion-dipole interactions with CB7’s carbonyl-lined portal.

This dissertation focuses on the investigation of gas-phase characteristics of cucurbituril host-guest systems using ion mobility spectrometry (IMS) and related techniques. Collision cross-sections (CCS) of alkylammonium complexes of cucurbit[n]uril (CB[n]) are measured to understand the allosteric interactions that induce conformational changes in the complex in the presence of metal cations on one of the portals of the cucurbit[6]uril (CB[6]) host. Cationic species on one CB[6] rim sterically force longer linear alkylammonium guests out of the cucurbituril cavity during complex formation. Similarly, rigid cucurbituril-metal complexes were studied using IMS to demonstrate the effect of long-range ion-neutral interactions on the gas phase mobility of ions. The contributions of charge state and charge distribution to the ion mobility CCS measured using a drift tube ion mobility spectrometer (DTIMS) were studied. This IMS method characterization will help in the study of biomolecules and may answer some of the questions regarding CCS measurements in protein structures, that are still being debated. While most of the studies were done using an IMS system, this dissertation also includes gas phase characterization studies done using Fourier transform ion cyclotron resonance (FTICR) mass spectrometry. A novel gas-phase CCS measurement technique - cross sectional areas using Fourier transform ion cyclotron resonance mass spectrometry (CRAFTI) was attempted on bigger systems like the [cucurbit[6]uril-n-alkylammonium]+ complexes. Infrared multi-photon dissociation (IRMPD), collision induced dissociation (CID), and sustained off-resonance irradiation (SORI) studies were done on many CB[n] systems, which helped to extract useful structural information about the complexes.

The literature of Medieval Europe has been studied so extensively that there are a great number of academic contributions that can be analyzed by current and future generations. The purpose of this particular work is to examine this topic, but as it pertains to the Medieval Iberian Peninsula. The medieval age of Spain has been considered a period wrought with conflict and religious persecution throughout the confines of its borders. From the inception of the invasions of various European tribes into the Iberian Peninsula, the stage was set for a continual onset of conquest for many years to come. This conquest took place during the 800 years that the Muslims maintained control of the southern half of the Medieval Iberian Peninsula. Such an occupation was achieved by way of the Strait of Gibraltar in which a mixed force of Arabs and Moroccan Berbers overthrew the Visigothic kingdom, giving this Muslim power an unquestioned supremacy (O'Callaghan 1). In an effort to closely examine this period, this study analyzed Las jarchas, El cantar de mio Cid, and Las coplas por la muerte de su padre. The first two literary works written anonymously, the third by Jorge Manrique. With all three being key works from the Iberian Peninsula during the early part of the Middle Ages, the goal was to apply their principles to modern day culture. This work has interpreted in depth the code of honor and its use during the Middle Ages as a key element of its time, and has demonstrated that it is no longer followed as closely as it once was. It has supported the idea that although the Medieval Iberian Peninsula saw its conflicts, there was in fact a certain level of coexistence among the various religious groups sharing the peninsula. Along with these findings, this work presents the conclusion that although the distance in time is clear, it is important to analyze the literary works of the past in order to have a clearer image of what the life and culture may have been like for the individuals who lived and breathed when the Middle Ages was their present time.

Processos de fragmentação são ferramentas fundamentais no estudo de íons por espectrometria de massas, pois permitem a obtenção de informação sobre a estrutura e termoquímica destes íons . Desenvolvemos uma técnica de dissociação de íons baseada na ativação destes através da absorção multifotônica sequencial de radiação infravermelha de um filamento incandescente. Nesta técnica, íons aprisionados na cela de um espectrômetro de massas por transformada de Fourier são submetidos a radiação do filamento por intervalos de tempo relativamente longos (da ordem de segundos), e passam por um processo de multíplos eventos de absorção e emissão de radiação, até a energia interna dos íons atingir um nível suficiente para a fragmentação. A partir deste modelo para o processo foram implementados métodos computacionais que permitem a simulação da dissociação. A realização destas simulações exige o conhecimento do espectro vibracional do íon, que normalmente tem que ser obtido por algum método teórico de cálculo, como foi feito neste trabalho paro o caso de alguns dos íons estudados. O método de dissociação unimolecular induzida por absorção de radiação infravermelha foi aplicado na determinação das energias de ativação e de dissociação dos íons moleculares de acetofenona, p-cimeno e cumeno. Este método também mostrou-se capaz de diferenciar diferentes estruturas isomericas, e foi com esta finalidade aplicado no estudo da isomerização ceto-enol do íon molecular de acetofenona. Demonstrou-se também a capacidade do método dissociar os íons moleculares de n-butilbenzeno e brometo de alila. / Fragmentation processes are fundamental tools for the mass spectrometric study of ions because they provide information on structure and termochemistry of these ions. We have developed a dissociation technique that is based on the multiphoton activation of trapped ions by infrared radiation emitted by an incandescent filament. In this technique, ions trapped in the cell of a Fourier Transform mass spectrometer are exposed to the filament radiation for long time periods (seconds), and a process of multiple absorption and emition events occurs, until the internal energy of the ions is high enough for fragmentation. Computational methods have been implemented from this model allowing for simulation of the dissociation process. For this simulation the ion vibrational spectra, that normally must be obtained from theoretical calculations, is also required, as has been done in this work for some of the studied ions. The method of unimolecular dissociation induced by infrared radiation was applied to the determination of activation and dissociation energies of the molecular ions of acetophenone, p-cymene and cumene. This method also proved to be capable in the differentiation of isomeric structures, and was so applied in the study for the keto-enol isomerization of the acetophenone molecular ion. It was also shown that the method can dissociate the molecular ions of n-butylbenzene an allyl bromide.
