The aim of this thesis is to analyse the personal pronoun “we” in a political debate using Conversation Analysis as research method. More specifically, the thesis aims to identify and analyse how the speakers of a political debate use “we” to express different referential domains in terms of group affiliation. Consequently, to support the thesis’s aim, the following research questions have been devised: What different categories of “we” can be found in the debate? How and when are these different categories used to manifest group affiliation and what do they accomplish?

L'étude de la structure interne des hadrons nous permet de comprendre la nature des interactions entre les partons, les quarks et les gluons, décrites par la Chromodynamique Quantique. Les processus de diffusion élastique, qui ont été utilisés avec succès pour mesurer les facteurs de forme des nucléons, sont inclus dans ce cadre. Les processus inélastiques sont également inclus dans ce cadre, ils nous permettent d'extraire beaucoup d'information grâce au développement des distributions de partons (PDFs). Par conséquent, tandis que la diffusion élastique d'électrons par le nucléon nous fournit des informations sur la répartition des charges, et donc de la distribution spatiale des composants du nucléon, la diffusion inélastique présente des informations sur la distribution d'impulsions au moyen des PDFs. Cependant, dans les processus inélastiques, il est possible d'étudier les processus exclusifs tels que la Diffusion Compton Profondément Virtuelle (DVCS), qui nous permet d'accéder aux distributions spatiale et d'impulsions des quarks simultanément. Ceci est possible grâce aux fonctions généralisées des distributions de partons (GPDS), qui nous permettent de corréler les deux types de distributions. Le processus connu sous le nom DVCS est le moyen le plus facile pour accéder aux GPDS. Ce procédé implique la diffusion d'un électron par un proton, au moyen de l'échange d'un photon virtuel, qui entraîne la diffusion des particules initiales et l'émission d'un photon réel. Ce processus est en concurrence avec le processus dit Bethe-Heitler, dans lequel le photon réel est émis par l'électron initial ou final. En raison de la faible section efficace de ce type de procédé, de l'ordre du nb, il est nécessaire d'utiliser une installation capable de fournir une haute luminosité pour réaliser les expériences. L'une de ces installations est le Thomas Jefferson National Accelerator Facility, où l'expérience appelée “Complete Separation of Virtual Photon and π⁰ Electroproduction Observables of Unpolarized Proton” a été réalisée au cours de la période entre Octobre et Décembre de 2010. Le principal objectif de cette expérience est la séparation de la contribution du terme provenant du DVCS à partir du terme d'interférence, résultant de la contribution du BH. Cette séparation est appelée “Séparation Rosenbluth”. Cette thèse porte sur le calorimètre électromagnétique qui a été utilisé pour détecter le photon dans l'expérience E07-007 à Jefferson Lab. Il y a aussi une introduction théorique à l'étude de la structure du nucléon, en révisant les concepts de facteurs de forme et des distributions de partons à travers des processus élastiques et inélastiques. Le calcul de la section efficace de la leptoproduction de photons est décrite en détail, ainsi que les buts de l'expérience E07-007. Dans cette thèse on décrit l'analyse des données enregistrées par le calorimètre électromagnétique, avec le but d'obtenir les variables cinématiques des photons réels résultants des réactions DVCS. Finalement, on décrit la sélection des événements à partir des données stockées, les réductions appliquées aux variables cinématiques et la soustraction de fond. En outre, le processus d'extraction des observables nécessaires pour le calcul de la section efficace de la leptoproduction de photons est décrite, ainsi que les principales étapes suivies pour effectuer la simulation Monte-Carlo utilisée dans ce calcul. Les sections efficaces obtenues sont indiquées à la fin de cette thèse. / The study of the inner structure of hadrons allows us to understand the nature of the interactions between partons, quarks and gluons, described by Quantum Chromodynamics. The elastic scattering reactions, which have been studied in order to measure the nucleon form factors, are included in this frame. The inelastic scattering reactions are also included in this frame, they allow us to obtain information about the nucleon structure thanks to the development of the parton distribution functions (PDFs). While through elastic scattering we can obtain information about the charge distribution of the nucleon, and hence, about the spatial distribution of the partons, through inelastic scattering we obtain information about the momentum distributions of partons, by employing the PDFs. However, we can study the exclusive inelastic scattering reactions, such as the Deeply Virtual Compton Scattering (DVCS), wich allow us to access to the spatial and momentum distributions simultaneously. This is possible thanks to the generalized parton distributions (GPDs), which allow us to correlate both types of distributions. The process known as DVCS is the easiest way to access the GPDs. This process can be expressed as the scattering of an electron by a proton by means of a virtual photon with the result of the scattered initial particles plus a real photon. We find a process competing with DVCS known as Bethe-Heitler (BH), in which the real photon is radiated by the lepton rather than the quark. Due to the small cross section of DVCS, of the order of nb, in order to conduct these kind of experiments it is necessary to make use of facilities capable of providing high beam intensities. One of these facilities is the Thomas Jefferson National Accelerator Facility , where the experiment JLab E07-007, “Complete Separation of Virtual Photon and π⁰ Electroproduction Observables of Unpolarized Protons”, took place during the months of October to December of 2010. The main goal of this experiment is the isolation of the contribution from the term coming form the DVCS from the interference term, resulting from the BH contribution. This isolation is known as “Rosenbluth Separation”. The work presented in this thesis focuses on the analysis of the data stored by the electromagnetic calorimeter, employed for the detection of real photons. There is also a a theoretical introduction to the study of the nucleon structure, reviewing the concepts of form factors and parton distributions through elastic and inelastic processes. The computation of the photon leptoproduction cross section is described in detail, as well as the goals of experiment E07-007. This thesis also describes the analysis of the data stored by the electromagnetic calorimeter, with the purpose of obtaining the kinematic variables of the real photons resulting from DVCS reactions. Finally, it describes the selection of events from stored data, the applied cuts to kinematical variables and the background subtraction. Also, the process of extraction of the necessary observables for computing the photon leptoproduction cross section is described, along with the main steps followed to perform the Monte Carlo simulation used in this computation. The resulting cross sections are shown at the end of this thesis.

Dans ce travail de thèse est présentée l’analyse des électroproductions exclusives des mésons f ₀ (980) et f₂(1270) sur le proton. Les données ont été acquises pendant l’expérience e1-6 (2001-2002) avec le détecteur CLAS du Jefferson Lab aux États-Unis, en utilisant un faisceau de 5.754 GeV et une cible de dihydrogène. Nous avons mesuré pour la première fois au monde les sections efficaces réduites différentielles de ces deux processus, dans le domaine cinématique 1.5 < Q2 < 4.3 GeV2 et 0.15< xB < 0.55. Nous proposons une interprétation de nos résultats sur une approche basée sur des degrés de liberté hadronique et la théorie de Regge. Une analyse des données en termes d’amplitudes d’ondes partielles et en terme de moments des distributions angulaires a également été tentée. Enfin, nous avons effectué la calibration des photomultiplicateurs du détecteur central de neutron (CND) pour le détecteur CLAS12. Le CND a été optimisé pour l’étude du processus n-DVCS (Diffusion Compton Profondément Virtuelle du neutron). / We present in this report our results for the exclusive electroproductions of f₀(980) and f₂(1270) off the proton. The data were taken during the e1-6 experiment (2001-2002) with the CLAS detector of Jefferson Laboratory, using a 5.754 GeV beam and a liquid hydrogen target. We have measured for the first time the reduced differential cross sections for these two processes, in the kinematical region 1.5 < Q2 < 4.3 GeV2 and 0.15< xB < 0.55. We propose an interpretation of our results according to a Regge-based model. An alternative analysis of the data in terms of partial waves amplitudes as well as in terms of moments of the decay angular distributions has also been attempted. Finally, we have performed the calibration of the photomultipliers of the Central Neutron Detector (CND), to be installed in the CLAS12 detector. The CND has been optimized for the study of the n-DVCS process (Deeply Virtual Compton Scattering off the neutron).

A city hall BRNO – North – dissertation 2015 A public building with the main function for the city hall for city part Brno – North. The building is extended with a representative hall which is also used for the culture and sociable events. Furthermore, this building includes a ceremonial hall, a cafe and a lecture room. A designed building of the city hall is situated in the centre position in a designed building. A close connection with Provaznikova street provides a connection to a current building a good accessibility for pedestrians and also for cars. At first was built the city hall, neverthless during following steps it would fit in the designed building. A position „centre“ and it´s own importance of the city hall allows to create a new strong binding with a current territory since it´s beggining. The public building and a public open space fill in this territory with an active life in a public space. A material solution of the city building reacts on a current and a future urban context. The traffic connection continues with a current communication. An entrances into the building are from Provaznikova street and a suggested square. An entrace to underground garages are on right side from a main entrance in a new designed street. A concept of the city hall includes two materials connected by communication hall which closes a public area of the square. Materials in a ground plan creates almost letter U. A combination of offices, servises for citizens, a multifunctional hall, a ceremonial hall and a cafe offer an optimal contain for a current and aslo for a future city hall. The height of building is moderate and isn´t higher than a designed or sorrounded buildings. A criterion of the building shows a kindness to people going by and also an honour to it´s meaning. A significant architectonic point of the city hall is a rotating arcade created by colonnade in an axial distance 2m and height 6,5m. This point itself contributes to an extraordinariness of this building and refers to Greek archatype. A regularity, a rast and a tectonics in all building is based on a constructive module which influenced an inner layout structure. A strenght and a stability is impared by a facade from a classical obverse masonry which has two visual solutions for an administrativelly – authoritilly part and more decorated for a part with a hall and a hall. A transparency of developments which is connected with a phylosophy of the city hall is shown in a glass entrance hall, furthermore in a solutions of corridors and offices and all kinds of boardrooms. The building is designed with a consideration of a premanently sustainable developement and management with energies, as a sustainable building.

This cross-sectional exploratory and descriptive quantitative study explored the factors that impact on feeding practices of infants 0-12 months, encountered in the Child Welfare Clinic in Tema Manhean Health Centre and to determine the possible factors that lead to malnutrition. The population for this study comprised all infants who attended the Child Welfare Clinic at the Tema Manhean Health Centre. Three hundred and ninety infants participated in this study. Data was collected by means of a structured questionnaire and analysed using the Statistical Package for the Social Sciences (SPSS) Version 20. Findings of the study revealed that a larger number of the mothers were still breastfeeding at the time of data collection. All infants aged six months or older were given complementary foods. Some of the factors found to be associated with infant malnutrition included education of mother, employment status of mother, marital status, cultural practices and parity. / Health Studies / M.A.(Public Health)

Una de las respuestas ante el caótico problema de la congestión vehicular utilizadas por varias ciudades del mundo es la implementación de sistemas de transporte masivos. Si bien tiene resultados positivos, a veces por una mala implementación del sistema los resultados no son los esperados. Esto no es ajeno a la realidad nacional, en Lima, por ejemplo, uno de los principales Corredores Complementarios (corredor rojo) viene presentando deficiencias en su operación debido a los altos índices de congestión dentro de su recorrido, demostrando que no tiene las condiciones idóneas para un buen funcionamiento. Por ello, en el presente trabajo de investigación se propone una ampliación de la Av. Javier Prado Oeste a través de la implementación de un cuarto carril de uso exclusivo para los buses ubicado a la derecha de la vía recortando el área verde central existente. Para ello se realizó la toma de datos en campo, procesamiento y análisis mediante el modelo de micro simulación en el software Vissim 9.0, el cual fue calibrado y validado mediante el indicador GEH. Se obtuvieron mejoras en la velocidad del Corredor Complementario rojo (incrementándose en 3 veces aproximadamente), longitudes de cola en las intersecciones (disminuyendo un 31% en la intersección Las Palmeras y un 52% en Las Flores) y niveles de servicio (pasando de un nivel de servicio E a D en ambas intersecciones) dentro del tramo delimitado. Esta propuesta debe ser implementada con políticas de movilidad y herramientas tecnológicas de señalización a favor del transporte público. / One of the responses to the chaotic problem of traffic congestion used by various cities around the world is the implementation of mass transportation systems. Although it has positive results, sometimes due to a bad implementation of the system the results are not as expected. This is not alien to the national reality, in Lima, for example, one of the main Complementary Corridors (red corridor) has been presenting deficiencies in its operation due to the high rates of congestion within its route, showing that it does not have the ideal conditions. for good operation. For this reason, in this research work an extension of Av. Javier Prado Oeste is proposed through the implementation of a fourth lane for exclusive use of buses located to the right of the road, cutting the existing central green area. For this, data collection, processing and analysis were carried out in the field using the micro simulation model in Vissim 9.0 software, which was calibrated and validated using the GEH indicator. Improvements were obtained in the speed of the Red Complementary Corridor (increasing by approximately 3 times), queue lengths at the intersections (decreasing by 31% at the Las Palmeras intersection and by 52% at Las Flores) and service levels (going from a service level E to D at both intersections) within the delimited section. This proposal must be implemented with mobility policies and technological signaling tools in favor of public transport. / Tesis

Établissant une relation entre un État ou l’une de ses émanations, d’une part, et un investisseur d’autre part, le droit des investissements étrangers se meut au-delà de la distinction droit public/droit privé. Compte tenu du fait qu’il se situe à un point de jonction entre le droit international et le droit interne, le droit des investissements pose d’importantes questions relatives à la loi applicable, ainsi qu’aux juridictions compétentes. Conçu comme un ordre juridique spécifique provenant de l’interaction entre les ordres juridiques international et interne, le droit des investissements engendre de multiples répercussions quant à son interférence avec l’ordre juridique interne. Cette interférence, n’étant soumise à aucune hiérarchie de compétence législative ou juridictionnelle, soulève de sérieuses interrogations : quel serait le droit applicable lorsque les droits interne et international ont vocation à s’appliquer dans un même litige ? Dans le même ordre d’idées, quelle serait la juridiction compétente si les institutions juridictionnelles internationales et internes sont toutes les deux compétentes selon leurs propres règles de rattachement pour trancher le litige ? Les réponses à ces interrogations ne sont pas évidentes et continuent de donner lieu à de vifs débats. La question n’ayant pas été tranchée de façon ferme et définitive, la présente étude proposera d’y apporter des éléments de réponse en démontrant la manifeste prééminence du droit international de fond et de l’arbitrage transnational de nature à permettre d’écarter l’application de la loi locale et d’exclure la compétence des juges internes. Cette prééminence fera enfin l’objet d’un examen approprié. / Establishing a relationship between a State or one of its emanations, on the one hand, and an investor, on the other, international investment law moves beyond the distinction between public law and private law. Given the fact that it resides in-between international law and domestic law, international investment law raises important questions about the governing law and jurisdiction. Conceived as a specific legal order arising from the interaction between the international and the national legal orders, international investment law begets controversy with respect to its interference with the national legal order. This interference, which is not submitted to any hierarchy on the legislative or jurisdictional level, raises serious questions: what would be the applicable law when domestic law and international law are both involved in the same dispute? In a similar manner, what would be the competent court if the international and domestic jurisdictional institutions are both competent according to the rules of their own legal order? The answers to these questions are not obvious and continue to give rise to heated debates. As the issue has not been firmly and definitively resolved, the present study aims to provide an answer by demonstrating the pre-eminence of substantive international law and transnational arbitration to the point of clearly excluding the application of the local law and the competence of domestic judges. This pre-eminence will finally be subject to an in-depth examination.

An increase in international trade has resulted in an increase in the carriage of goods by sea, which has also promoted the business of marine insurance on a very huge scale. Marine insurance contracts fall within both the admiralty jurisdiction where admiralty laws apply and special contract law where the rules and principles of contract law apply. In certain circumstance this has left the courts with a dilemma in deciding in particular cases which law should apply; whether maritime law, contract law or marine insurance law. There are certain principles under the law of contract that are said to be profound and cannot be ousted easily by substantive law. The principle of party autonomy is one of these principles and it has gained international recognition through a number of cases. However, to date, courts are faced with difficulties in deciding whether to uphold the choice of law on jurisdiction and governing law exercised by parties or resort to substantive law, either by virtue of admiralty law or any other statutes in a country, which provisions may be contrary to the clause on choice of law under the contract. In South Africa practice has shown that courts are always reluctant to apply the clause on choice of law if they believe such application is against the public policy and interest in South Africa. This begs the question as to the precise meaning and effect of “public policy and interest” and how this principle influences the long-standing and well-established principle of party autonomy in admiralty jurisdiction. This dissertation is aimed at providing a legal response to this problem by analysing case law and the different viewpoints of various writers. It is imperative to investigate if their decisions and views answer all the uncertainties with regard to the meaning and the effect of the concept of “public policy and interest” on the principle of party autonomy. / LLM (Import and Export Law), North-West University, Potchefstroom Campus, 2014

The aim of this study was to assess the extent on how effective was the prevention of mother-to-child transmission of Human Immunodeficiency Virus (HIV) infection at Oshakati District Health Centre. Explanatory survey was used to conduct the research. A total of 160 nurses experienced in prevention of mother-to-child transmission and women who attended antenatal care and post natal care services participated in the study. Respondents expressed unsatisfactory with the promoting involvement of male partners, high quality voluntary counselling and testing services, couple counselling and testing, integration of Highly Active Antiretroviral Therapy services, administration of short course of Zidovudine to pregnant mothers and the provision of antiretroviral drugs to infants. Therefore, promoting involvement of male partners, couple counselling and testing, administration of short course of Zidovudine to pregnant mothers and educating women about exclusive breastfeeding prior to delivery are some of recommendations for effective prevention of mother-to-child transmission of HIV infections. / Health Studies / (M.A. (Public Health))
