This paper sought to analyse which underlying motives impacted the stances and policies taken by Greece and Türkiye regarding their disputed maritime border. The maritime border consists of two distinct areas, the Aegean Sea, and the Eastern Mediterranean Sea. The analysis chose to study the two areas separately since there are differences between them. The study was conducted through the lens of Morgan and Palmer’s general theory of foreign policy, in which a state either acts reactively to preserve the current situation, or proactively to try and change it. The result of the study shows that both states acted because of security related, economic, and hegemonic motivations as well as to protect their sovereignty and national rights. Security concerns played a significant role in the dispute, as both states deemed the other to be a threat. Because of this, both Greece and Türkiyeacted reactively against each other. At the same time, Türkiye was also found to be more likely to act proactively compared to Greece who often either acted in response to Türkiye or indirectly through its allies such as the EU or Egypt.

The study sought to explore and describe the breastfeeding practices of Human Immunodeficiency Virus (HIV) positive postnatal clients’ non-commitment to exclusive breastfeeding in George Mukhari Hospital, South Africa. A non-experimental quantitative design was used. Inferences drawn from the study were that HIV positive clients that opted for exclusive breastfeeding did not commit for fear of transmission of HIV to the baby and exclusive breastfeeding was stopped before the recommended 6 months. Most of the respondents’ partners did not come for counselling. There was lack of emotional support by staff after testing. Health education and emotional support of HIV positive clients has to be intensified. / Health Studies / M. A. (Health Studies)

To determine the relationship between infant-feeding practices and diarrhoeal infections, a descriptive survey was conducted to infants between six to 12 months of age. A guided interview was conducted to 105 mothers of infants who attended the health facilities of Mbabane, Swaziland. The results show that breast-feeding is routinely practiced by the majority of mothers and exclusive breast-feeding is very low, but supplementary feed in the form of formula or solids are introduced by the majority of respondents within the first three months of life. Infants who were given colostrum and breast milk had fewer diarrhoeal attacks. Other factors, for example education and cultural factors influenced the feeding practices and number of diarrhoeal attacks. It is recommended that breast-feeding should be promoted as an important intervention in the control of diarrhoea / Health Studies / M.A. (Nursing Science)

This thesis examines how exclusive women's magazines readers approach the category of luxury, their relationship with products announced in these magazines and whether the feeling of luxury, aroused by such magazines, is affiliated with a certain social class. This thesis also focuses on question whether these readers regard physisal atractiveness as a sign of social status. The theoretical part of this thesis describes several concepts which are important in the context of media studies: social constructivism, the process of understanding media effects, the conception of uses and gratification and the role of mass media in the socialization process. This part further elaborates on exclusive women's magazines, conceptions of lifestyle, luxury, fashion and its importance for identity construction. The methodological part introduces the methodology of the analysis and the analysis itself. The sample used for this analysis was composed of ten respondents which were subjected to an in-depth interview. Each interview also included reception analysis. The following chapters describe the results of this analysis.

Les créances monétaires constituent une excellente source de crédit et les sûretés sur créances existent en droit français, droit anglais et droit vietnamien. Cependant, si elles sont reconnues de longue date en droit anglais, l’évolution de leur régime juridique est récente en droits français et vietnamien. Par ailleurs, si ces trois droits connaissent tous les sûretés traditionnelles sans transfert de propriété (nantissement de créances, charges sur les créances et hypothèque de créances), l’admission en droit français des seules fiducie sur créances et cession de créances professionnelles à titre de garantie par bordereau Dailly ainsi que le rejet par les juges vietnamiens des cessions innommées à titre de garantie démontrent que l’exploitation de la fonction de garantie de la propriété d’une créance n’est pas encore généralisée en France et au Vietnam à la différence de ce que l’on peut observer en droit anglais à travers la "mortgage"par voie d’"assignment" ou de novation. Enfin, l’hypothèque de créance de droit vietnamien et la "fixed charge" sur les "bookdebts" de droit anglais démontrent qu’une sûreté non basée sur le transfert de propriété peut être tout à fait efficace que ce soit dans un contexte de solvabilité ou de procédure collective du titulaire de la créance.Ces approches révèlent tout l’intérêt d’une entreprise doctorale mise en perspective des nombreux investissements économiques et montages financiers impliquant, de façon croissante, des acteurs économiques et partenaires bancaires internationaux dont les intérêts, les enjeux et les stratégies relèvent par construction, ou nécessité,des ordres juridiques précités. / Receivables constitute an excellent source of credit and security over receivables is available under French, English and Vietnamese law. However, if they have been recognised in English law for a long period of time, their development is quite recent in French and Vietnamese law. Moreover, although these three legal systems recognise all traditional security interests which are not based on the transfer of ownership over secur ed receivables (nantissement de créances in French law, floating and fixed charge over book debts in English law and hypothecation over debt claims in Vietnamese law), the fact that French law only recognises fiducia over receivables and assignment of trade receivables by way of security and Vietnamese judges have rejected the transfer ofownership by means of security, demonstrates that the use of functionality of ownership over receivables has not become widespread in France and in Vietnam. In contrast, in England, mortgages over receivables allow for the transfer of ownership as security, whether by way of an assignment or a novation. Finally, the hypothecation over debt claims of Vietnamese law and the fixed charge over book debts of English law show that security that does not entail the transfer of ownership can be perfectly efficient inside and outside insolvency proceedings.These approaches reveal the interests of a doctoral enterprise put in perspective from numerous economic investments and financing structures involving, in a rising fashion, economic stakeholders and international bank partners whose interests,stakes and strategies fall under (by construction, or necessity) the aforementioned jurisdictions

Le sujet de cette thèse sont les amplitudes d'hélicités de la leptoproduction exclusive et diffractive du méson rho dans la limite de Regge perturbative et au-delà du twist dominant. La compréhension de pareils processus exclusifs en termes des constituants élémentaires de QCD est un important défi pour comprendre la structure des hadrons. On présente ici deux nouveaux modèles phénoménologiques basés sur la kT-factorisation des amplitudes d'hélicités en un facteur d'impact γ*(λ) → ρ(λ'), où λ et λ' dénotent les polarisations du photon virtuel et du méson rho, et le facteur d'impact du nucléon cible. Les facteurs d'impacts γ*(λ) → ρ(λ') sont calculés en utilisant la factorisation colinéaire pour séparer la partie molle du méson rho. Le premier modèle est obtenu en combinant les résultats respectivement de twist 2 et twist 3 des facteurs d'impacts où les deux polarisations sont longitudinales ou transverses, avec un modèle pour le facteur d'impact du nucléon et un modèle pour les distributions d'amplitudes du méson rho. Dans la seconde approche présentée dans cette thèse, on calcule ces facteurs d'impacts dans l'espace des paramètres d'impacts et on montre que l'amplitude de diffusion d'un dipôle de couleur avec le nucléon se factorise, permettant de combiner nos résultats avec un modèle de section efficace de dipôle. On obtient en très bon accord avec les données de H1 et ZEUS pour des virtualités plus grandes que quelques GeV. Nous discutons les résultats obtenus et les comparons à d'autres modèles existants. / This thesis deals with the computation of the helicity amplitudes of the exclusive diffractive rho meson leptoproduction in the perturbative Regge limit beyond the leading twist. The understanding of such exclusive processes in terms of the elementary constituents of QCD is a serious challenge to understand the hadronic structure. We present two new phenomenological models based on the kT-factorization of the helicity amplitudes in a γ*(λ) → ρ(λ') impact factor, where λ and λ' denote the polarizations of the virtual photon and the rho meson, and the nucleon target impact factor. The γ*(λ) → ρ(λ') impact factors are then computed using the collinear factorization of the rho meson soft part. The first model relies on the combination of the results respectively up to twist 2 and twist 3 for the impact factors where both polarizations are longitudinal or transverse, with a model for the nucleon impact factor and a model for the distribution amplitudes of the rho meson. In the second approach presented in this thesis, we derive these impact factors in impact parameter space and show that the color dipole scattering amplitude with the nucleon factorizes, allowing to use our results in combination with dipole cross-section models. We get a very good agreement with the data from H1 and ZEUS collaborations for virtualities higher than a few GeV. We discuss our results and compare them to other models.

Le personnel des gouverneurs des colonies sous la période royale regroupe les gouverneurs généraux et particuliers qui administrent les colonies françaises de 1763 à 1792 sous l’autorité de la couronne. Le gouverneur est un homme de guerre, choisis par le ministre de la Marine et nommé par le roi. Il s’agit pour lui de défendre un empire, de contrôler les pratiques locales et de veiller à l’exécution des lois du royaume. La nature de la charge et l’étendue des pouvoirs s’adaptent aux circonstances locales, sans oublier la personnalité et l’envergure du titulaire, sa position sociale, les cumuls de fonctions dont il peut bénéficier. Si la place de premier personnage de la colonie, l’appartenance à l’élite administrative et la prérogative de représentant du roi laissent supposer un poste brillant, la réalité est moins reluisante. L’autorité du gouverneur est affaiblie par de nombreux obstacles à un exercice efficace du pouvoir. Le gouverneur tente d’asseoir sa puissance sur d’autres marqueurs distinctifs, mais la réalité de la charge reste peu enviable, faite d’un mélange d’insalubrité et de déplacements, en proie à la méfiance des élites locales ou des autres administrateurs métropolitains. Les compensations financières et l’argument de promettre une place plus avantageuse après le gouvernement sont de plus en plus illusoires au fur et à mesure que le climat se complique à l’approche de la Révolution. La charge de gouverneur des colonies, poste de passage dans une carrière à forte dimension coloniale, est une charge isolée des cercles d’influence de la cour, atypique dans son recrutement et limitée dans les perspectives de carrière qu’elle offre à la fin du XVIIIe siècle. / The executive staff of colonial governors under royal period comprises governors-general and individuals who rule the French colonies from 1763 to 1792 by appointment of the crown. The governor is a man of war, appointed by the King on the advice of the Navy Minister. It is for him to defend an Empire, to control local customs and to enforce royal laws. The importance of the position and the range of power that comes with it depend on local circumstances, not to mention the personality and the scale of the holder, his social ranking, and the combining of functions he can benefit from. If being the ruler of the colony, being part of the administrative elite and representing the King suggest both a prestigious and exotic job, reality is less rosy. The governor's authority has to face numerous obstacles, which results in the weakening of the effective ruling of the country. The governor tries to assert power over other distinctive markers, however the office remains unenviable, as it implies squalor and constant travel and is plagued by distrust of local elites or other metropolitan administrators. The financial perks and the promise of a more prestigious position after serving as Colonial governor are increasingly unrealistic as the French Revolution approaches. The office of Colonial governor, one of several steps in a colonial career, is actually isolated from the power and influence which rule the court, atypical in its appointment and provides very few career opportunities.

A comparação de genomas, genes ou até sequências de nucleotídeos não condificantes é uma importante tarefa na qual a bioinformática pode ser aplicada, uma vez que ela auxiliar em diversas atividades, por exemplo, análises filogenéticas. Análise filogenética, por sua vez, busca analisar a relação evolutiva de cada espécie, considerando suas características genéticas. Esses processos e as técnicas que os implementam se baseiam em sequências de nucleotídeos sequenciadas e armazenadas em bancos de dados de genomas públicos. Com análise filogenética também é possível identificar possíveis origens de um gene. Essa tarefa é de grande importância, pois auxilia na identificação da origem de genes patogênicos, podendo auxiliar no combate e prevenção do surgimento de doenças. Um problema potencial dessas sequências é a possibilidade de haver erros nas anotações (marcações de sequências como genes). Esses erros são pouco explorados por pesquisadores atualmente. Outro tema pouco explorado é a análise filogenética de genes exclusivos, que são genes que se manifestam em apenas uma espécie, considerando um grupo de espécies próximas. A identificação de genes exclusivos de alguma espécie pode servir para a correta identificação de, por exemplo, a espécie que causa uma doença, de forma a permitir o uso do tratamento mais específico e adequado. A importância da descoberta de filogenias de genes exclusivos e a dificuldade de garantir a consistência nas anotações genéticas motivaram este trabalho, que teve como objetivo implementar ferramentas para interpretar dados de comparação genética, identificando potenciais erros em anotação de genes exclusivos e criando estratégias para identificar a origem desses genes. As origens de genes exclusivos exploradas neste trabalho envolvem a possibilidade dos genes exclusivos terem derivado de outras famílias de genes do próprio organismo, ou, os genes exclusivos se diferenciaram muito dos genes ancestrais. Essas hipóteses, juntamente com a hipótese da existência de erros de anotação, foram exploradas em experimentos utilizando as ferramentas desenvolvidas. Os experimentos visaram a analisar a aplicabilidade da estratégia desenvolvida. Foram utilizados genomas de bactérias do gênero Xanthomonas, que contém um grande grupo de bactérias que causam doenças em plantas. Os resultados obtidos demonstram que existe uma quantidade considerável de potenciais erros de anotação nos genomas considerados, provando a hipótese de que a inconsistência nas anotações genômicas possui grande influência para a dificuldade na identificação de filogenias (tanto de genes exclusivos como para não exclusivos). Os resultados também demonstraram que boa parte dos genes exclusivos possivelmente se originaram de outras famílias de genes do próprio genoma. Ou ainda, que esses genes sofreram modificações em relação aos genes ancestrais, mas ainda possuem certas semelhanças com sequências de nucleotídeos que não codificam genes em outras espécies mais distantes. Por fim, a estratégia desenvolvida se mostrou útil na análise filogenética das bactérias estudadas, sendo este um forte indício de que a mesma abordagem pode ser utilizada para problemas similares com outras espécies de seres vivos / Comparison of genomes, genes or even non-coding nucleotide sequences is an important task in which bioinformatics can be applied, since it allows the application of phylogenetic analyses. Phylogenetic analysis, in its turn, seeks to analyze the evolutionary relation of each species, considering its genetic characteristics. These processes and the techniques that implement them are based on nucleotide sequences sequenced and stores in databases of public genomes. With phylogenetic analysis it is also possible to identify possible origins of a gene. This task has a great importance, because it allows the identification of the origin of pathogenic genes, which may help to combat or prevent deseases. A potencial problem of these sequences is the possibility of having annotation errors (sequences marking as genes). These errors are little explored by researchers nowadays. Another unexplored topic is the phylogenetic analysis of exclusive genes, which are genes thaht manifest in only one species, considering a group of nearby species. The identification of exclusive genes of a species may serve to correctly identify, for example, a desease, in order to allow the use of a more especific and appropriate treatment. The importance of discovering phylogenies of exclusive genes and the difficulty of guaranteeing the consistency of genetic annotations motivated this work, whose objective was to implement tools to interpret data of genetic comparison, identifying annotation errors in exclusive genes and creating strategies to identify the origin of these genes.The origins of exclusive genes explored in this work involve the possibility of the exclusive genes have derived of other gene families of the organism itself, or, the exclusive genes differed a lot from the ancestral genes. Theses hypotheses, with the hypotesis of the existance of annotation errors, were explored in experiments using the developed tools. The experiments aimed to analyse the applicability of the developed strategy. Genomes of bacteria of the genus Xanthomonas were used, which contains a large group of bacteria that cause diseases in plants. The results show that there is a considerable amount of annotation errors on the genomes, proving the hypothesis that the inconsistency in genomic annotations has a great influence on the difficulty in identifying phylogenies (both exclusive and non-exclusive genes). The results also show that much of exclusive genes possibly originated from other gene families of the genome itself. Furthermore, these genes may have sufferedmodifications in relation to the ancestral genes, but still have certain similarities with nucleotide sequences that don\'t encode genes in other more distant species. Finally, the strategy developed proved useful on phylogenetic analysis of the studied bacteria, which is a strong indication that the same approach can be used for similar problems with other species of living beings

Introdução: Os múltiplos e interativos efeitos protetores do aleitamento materno exclusivo (AME) na saúde e sobrevivência infantil justificam as recomendações universais para promover sua prática. Poucos são os estudos que avaliam a tendência do padrão do AME entre países. Objetivo: Analisar a mudança temporal do AME em cinco países da América Latina e Caribe (ALC) comparando dados das décadas de 1990 e 2000. Métodos: A dissertação é composta por um manuscrito, que avaliou dados de crianças de 0 a 6 meses incluídas nas amostras das pesquisas Demographic Health Survey conduzidas em Brasil, Colômbia, Haiti, Peru e República Dominicana. Foram estimadas as prevalências do AME e suas taxas anuais de variação ponderada, segundo país e ano de inquérito. A duração do AME foi estimada usando a análise de sobrevida de Kaplan-Meier, considerando a idade atual da criança como o tempo de sobrevida e o AME como variável binária, referente à situação da prática no momento da entrevista. As curvas de sobrevivência foram construídas por país, em cada década, e a comparação entre elas usou o teste log-rank. A mediana do tempo de amamentação foi calculada para cada variável independente e a relação entre essas variáveis e o desmame até os seis meses foi analisada pela técnica de regressão de Cox com modelo múltiplo. Resultados: A prevalência de AME aumentou em quatro dos cinco países estudados, com incremento ao ano mais marcante na Colômbia (11 por cento ) e no Haiti (17 por cento ). A duração mediana apresentou duas tendências de evolução: aumento com equidade na Colômbia e no Haiti, e estagnação com distribuição desigual entre os subgrupos populacionais da última década no Brasil, Peru e República Dominicana. No modelo múltiplo de regressão, variáveis de demografia e do perfil de uso dos serviços de saúde associaram-se à duração do AME. A residência em área rural foi a variável reiteradamente associada, de forma negativa no Brasil (HR=1,68; IC 95 por cento :1,06-2,67) e na Colômbia (HR=1,39; IC 95 por cento :1,03-1,87), enquanto que positivamente no Peru (HR=0,40; IC 95 por cento :0,19-0,83). Conclusão: O balanço da tendência do AME na ALC é positivo, embora não uniforme ao longo das duas décadas analisadas. Os achados sinalizam a necessidade de intervenções para a promoção do AME que levem em consideração a localização geográfica das famílias e a qualidade prestada nos serviços de saúde / Introduction: Multiple and interactive protective effects of exclusive breastfeeding (EBF) in health and child survival justify recommendations for promoting universal practice. There are few studies that assess the tendency of the pattern of EBF between countries. Objective: To analyze the temporal change of the AME in five countries in Latin America and Caribbean (LAC) comparing data from 1990 and 2000 decades. Methods: The dissertation consists of a manuscript, which evaluated data from children aged 0 to 6 months in the samples of the Demographic Health Survey conducted research in Brazil, Colombia, Haiti, Peru and the Dominican Republic. Were estimated the prevalence of exclusive breastfeeding and its weighted annual rates of change, according to country and survey year. The duration of EBF was estimated using survival analysis Kaplan-Meier method, considering the current age of the child as the survival time and EBF as binary variable, concerning the state of practice at the time of the interview. The survival curves were constructed for each country, in every decade, and the comparison between them used the log-rank test. The median duration of breastfeeding was calculated for each independent variable and the relationship between these variables and weaning at six months was analyzed using Cox regression model. Results: The prevalence of EBF increased in four of the five countries studied, increasing the most remarkable years in Colombia (II per cent ) and Haiti (17 per cent ). The median duration of evolution showed two trends: growth with equity in Colombia and Haiti, and stagnation with unequal distribution among the population subgroups of the last decade in Brazil, Peru and the Dominican Republic. In the multiple model of regression variables and the demographic profile of use of health services were associated with duration of EBF. The residence in a rural area was the variable consistently associated negatively in Brazil (HR = 1.68, CI 95 per cent : 1,06-2,67) and Colombia (HR = 1.39, CI 95 per cent : 1,03-1,87), while positively in Peru (HR = 0.40, CI 95 per cent : 0,19-0,83). Conclusion: The balance of the trend of EBF in LAC is positive, though not uniform throughout the two decades analyzed. The findings suggest the need for interventions for the promotion of exclusive breastfeeding taking into account the geographical location of families and provided quality health services
