Hilda Pena Porto de Oliveira 08 November 2010 (has links)
O objetivo do trabalho é pesquisar indicadores que possibilitem aos usuários interessados, acompanhar o desempenho econômico e social dos municípios do Estado de São Paulo. Comparar cada indicador em relação ao seu objetivo, formulação, abrangência, periodicidade, responsabilidade, limitação e disponibilidade. Posteriormente, selecionar os indicadores que se mostraram mais apropriados para mensurar a desigualdade sócio-econômica entre os municípios. Parte dos dados obtidos serão espacializados com a geração de mapas temáticos utilizando o aplicativo desenvolvido pelo DATASUS, do Ministério da Saúde. A geração e utilização de Indicadores Sociais e Econômicos espacializáveis, além de possibilitar o conhecimento das condições de vida de uma população, é uma ferramenta fundamental para orientar as políticas públicas no sentido de promover o bem-estar social dos munícipes. / The objective of this research is to search for indicators to enable interested users to monitor the economic and social performance of the São Paulo States Municipalities. Comparing each indicator in relation to its objective, formulation, comprehensiveness, timeliness, responsibility, control and availability. Afterwards, to select the indicators that were more appropriate to measure the socioeconomic inequality among these municipalities. Part of the obtained data will be spatialized with the generation of thematic maps using an application developed by DATASUS, the Ministry of Health. The generation and use of Social and Economic Indicators, in addition to providing the knowledge of populations living conditions, is a suitable tool to guide public policies to promote the citizens welfare.

Orientador: Antonio Carlos Pereira / Dissertação (mestrado profissional) - Universidade Estadual de Campinas, Faculdade de Odontologia de Piracicaba / Made available in DSpace on 2018-08-25T23:32:42Z (GMT). No. of bitstreams: 1 Guerra_MariaSilviaBergo_M.pdf: 875000 bytes, checksum: f66d397442562d93e5033ed703495ebe (MD5) Previous issue date: 2014 / Resumo: O pré-natal inadequado e a gestação durante a adolescência são alguns dos fatores que, conhecidamente, interferem na saúde materno-infantil. Modelos conceituais defendem as condições contextuais e os modelos de atenção em saúde como determinantes nesse processo. Essa dissertação produziu dois artigos, que foram divididos capítulos e que tiveram como objetivos verificar como as variáveis contextuais e do modelo de atenção em saúde interferem: a.) na ausência de pré-natal (capítulo 1); e, b.) na gestação durante a adolescência (capítulo 2). Através de um estudo ecológico, em todos os 645 municípios do Estado de São Paulo, durante os anos de 1998 a 2008, pesquisou-se a tendência da ausência de pré-natal e da gravidez na adolescência, bem como possíveis variáveis contextuais e de modelo de atenção podem impactá-las. Para avaliar a ausência de pré natal, a variável dependente foi o coeficiente de nascidos vivos de mães que não fizeram pré-natal (zero consultas); e para avaliar a gestação na adolescência, utilizou-se como variável dependente o coeficiente de nascidos vivos de mães adolescentes (menores de 20 anos). Foram consideradas como características contextuais o PIB per capta e o número de habitantes, por município. Para avaliar o modelo de atenção, foram consideradas a proporção de equipes de Saúde da Família e de Agentes Comunitários de Saúde implantados, por município. Verificou-se que as características contextuais e do modelo de atenção foram significativas, ou seja, o PIB per capta (p<0,0001) e o número de habitantes de cada município (p<0,05) e proporção de equipes de Saúde da Família implantadas (p<0,05) interferiram na variação da ausência de pré-natal; e que, PIB per capta e proporção de Agentes Comunitários de Saúde influenciaram na variação de mães adolescentes(p<0,0001 e p<0,0013, respectivamente). A ausência de pré-natal e a gravidez na adolescência demonstraram tendência de queda, no Estado de São Paulo, no período estudado, influenciada principalmente pelo PIB per capta e pelo modelo de atenção em saúde / Abstract: Inadequate prenatal care and pregnancy during adolescence are some of the factors, known to interfere in maternal and child health. Conceptual models advocate the contextual conditions and models of health care as determinants in this process. This thesis has produced two articles, which were divided chapters and had as aim to verify how the contextual and the health care model variables affect: a) the absence of prenatal care (Chapter 1);. and b.) in pregnancy during adolescence (Chapter 2). Through an ecological study, in all 645 counties of the State of São Paulo, during the years 1998 to 2008, researched the trend of lack of prenatal care and teen pregnancy, as well as possible contextual variables and model attention may have an impact on them. To assess the absence of prenatal, the dependent variable was the ratio of live births to mothers who did not receive prenatal care (consultations zero); and to assess adolescent pregnancy, was used as the dependent variable coefficient of live births to teenage mothers (under 20 years). Contextual characteristics were considered as GDP per capita and the number of inhabitants per municipality. To evaluate the model of care were considered the proportion of Family Health Teams and Community Health Agents deployed, by municipality. It was found that the contextual features and the care model were significant, ie, GDP per capita (p <0.0001) and the number of inhabitants in each municipality (p <0.05) and proportion of Health teams deployed family (p <0.05) variation interfered in the absence of prenatal care; and that GDP per capita and proportion of community health workers influenced the variation in teenage mothers (p <0.0001 and p <0.0013, respectively). The lack of prenatal care and teen pregnancy have shown a declining trend in the state of São Paulo in the period studied, mainly influenced by per capita GDP and the model of health care / Mestrado / Odontologia em Saude Coletiva / Mestra em Odontologia em Saúde Coletiva

Localisation d'Anderson avec des atomes froids : dynamique dans le désordre et perspectives avec des modèles chaotiques / Anderson localization with cold atoms : dynamics in disorder and prospects from chaos

Prat, Tony 25 September 2017 (has links)
Dans cette thèse, nous étudions théoriquement plusieurs effets liés à la localisation d'Anderson, dans le contexte des atomes froids. Dans les systèmes d'atomes froids, le désordre est généralement créé à l'aide d'une figure de tavelure optique. Dans la première partie de la thèse, nous discutons des spécificités de ces potentiels optiques, et nous nous intéressons en particulier aux propriétés spectrales. Les expériences usant de l'interaction lumière-matière offrent d'intéressantes possibilités. Dans ce cadre, nous considérons dans une deuxième partie de la thèse l'étalement d'un paquet d'ondes atomique, initialement lancé avec une vitesse non nulle dans un potentiel désordonné. Nous trouvons qu'après un mouvement balistique, le centre de masse du paquet subit une rétro-réflection et retourne lentement à sa position initialle, se comportant comme un boomerang. Nous introduisons ensuite les interactions inter-atomiques dans une troisième partie. Nous considèrons des gaz dilués de bosons condensés, et traitons les interactions au niveau champ moyen. Plusieurs situations sont étudiées numériquement, en particulier le boomerang quantique, et l'étalement dynamique -- à la fois en impulsion et en énergie -- d'ondes de matière préparées en ondes planes. Dans la dernière partie de la thèse, nous montrons que des modèles chaotiques offrent des perspectives intéressantes pour l'étude de la localisation d'Anderson. D'une part, nous présentons des éléments probants en faveur d'un kick rotor sans spin dans l'ensemble symplectique. D'autre part, le réexamen de modèles communément étudiés de kick rotors quasi-périodiques révèle des résultats intrigants. / This thesis theoretically investigates several effects related to Anderson localization, focusing on the context of disordered and chaotic cold-atomic systems. In cold-atomic systems, optical speckle patterns are often used to create the disorder. The resulting potentials felt by the atoms differ from Gaussian random potentials, commonly assumed in the description of condensed-matter systems. In the first part of the thesis, we discuss their specificities, with an emphasis on the spectral properties. Atom-optics experiments offer interesting possibilities, such as the possibility to directly probe the atoms inside the disordered potential. In view of these possibilities, we consider in the second part of the thesis the spreading of matter wave packets initially launched with a non-zero velocity. We find that after an initial ballistic motion, the packet center-of-mass experiences a retroreflection and slowly returns to its initial position, mimicking a boomerang. Atom-atom interactions are then introduced in a third part. We consider dilute condensed bosonic gases, and treat the interactions at the mean-field (Gross-Pitaevskii) level. Various situations are studied numerically, in particular the quantum boomerang scenario, and the dynamical spreading both in momentum and energy of matter waves prepared as plane waves. In the last part, we show that chaotic models offer interesting prospects for the study of Anderson localization. On the one hand, we present strong evidences in favor of a spinless kicked rotor in the sympletic ensemble. On the other hand, a second look at a commonly studied quasi-periodically modulated kicked rotor reveals intriguing results.

Optical studies of polar InGaN/GaN quantum well structures

Blenkhorn, William Eric January 2016 (has links)
In this thesis, I will present and discuss research performed on InGaN/GaN multiple quantum well (QW) structures. The results of which were taken using photoluminescence (PL) spectroscopy and PL time decay spectroscopy. In the first two experimental chapters, I report on the effects of QW growth methodology on the optical properties of c-plane InGaN/GaN QWs. I compare structures grown using the single temperature (1T), quasi-two temperature (Q2T), temperature bounced (T-bounced) and two temperature (2T) QW growth methodologies. The T-bounced and 2T structures are observed to have gross well width fluctuations (GWWF), where the QW width varies from 0 to 100 % created when the QWs are exposed to a temperature ramp. Whereas, the 1T and Q2T structures have continuous QWs with only one or two monolayer well width fluctuations. The structures with GWWFs are observed to have a larger room temperature internal quantum efficiency (RT-IQE) at low excitation conditions i.e. below efficiency droop compared to those without. The larger RT-IQE is ascribed to several factors which include an increased radiative recombination rate, increased thermal activation energy of non-radiative recombination and reduced defect density of the QWs. The effect of barrier growth temperature is also investigated. No clear trend is observed between barrier growth temperature and RT-IQE.In the last experimental chapter I report on studies of carrier localisation in InGaN/GaN QWs using resonant PL spectroscopy. The effect of carrier localisation on the independently localised electrons and holes are investigated and the resonant PL spectrum is studied in detail. The InGaN/GaN QW structure is observed to exhibit an effective mobility edge at 12 K where delocalised carriers are created above a particular excitation energy. The emission from the resonantly excited localised states which are accompanied by the emission of a longitudinal optical phonon (resonant LO feature) is investigated as a function of temperature and excitation energy. The integrated PL intensity of the resonant LO feature is observed to quench rapidly with temperature up to around 45 K, independent of excitation energy. The integrated PL intensity of the resonant LO feature is fitted to an Arrhenius model and a thermal activation energy of ∼ 1(±1) meV is extracted. This activation energy is speculated to be consistent with the localisation energy of electrons.

NÁRODOHODSPODÁŘSKÉ DOPADY INSTITUCIONÁLNÍ RESTRUKTURALIZACE APLIKOVANÉHO ČESKÉHO ZEMĚDĚLSKÉHO VÝZKUMU / Institutional restructuring Czech Agricultural Research

Šlajs, Jan January 2017 (has links)
This dissertation entitled The Economical Implications of Institutional Restructuring of Applied Czech Agricultural Research solves the issue of effectiveness of applied national agrarian research, which is financed from public funds. The purpose of this thesis is to describe the current basis of applied agricultural research funded by the governance, respectively those scientific institutions that are eligible for an annual institutional grant to long-term development. Describe their focus and structure of results. Another purpose is to look for possible reserves in the system and to propose the restructuring of national applied agricultural research in organizations established by the Ministry of Agriculture of the Czech Republic. I have focused on comparing the outputs of scientific institutions in the periods of science and research support programs since 2007. In the data evaluated by the research institutions, I have been using bases in the last five years. From the point of view of the effectiveness of applied agricultural research, I am using data from 1989, respectively 2003. I solved the chosen topic of the dissertation by progressive steps. First, I evaluated the individual research institutions in terms of their outputs within the announced programs of support for science and research. I was looking for the argument that there is a substitute in the form of a private research organization in the current system of public research institutions. Which I didn´t find. State established applied agricultural research is unique in its content. For a comprehensive view, I have analysed the structure and types of research results achieved in the announced support programs. Problematics was solved mainly by comparison analysis based on literature, data and their aggregated results. The economic and social policy impacts are processed on the performance of the agriculture - food industry complex in terms of gross added value, socio-demographic data about workers in the field and complex. The dissertation proposes a new organization structure of applied agricultural research established by the state. A system of the central agriculture research organization is designed on the base of the current geographical distribution on the territory of the capital city Prague and Brno. The solution provides a more complex use of the existing unused potential of agriculture public research organizations. At the same time the standard elements of modern management are applied. Research has shown that the current system of funding science and research, which prefer quantity rather than output quality, is a major failure. At the same time, the work has shown that there is a way-out from the current fragmented system of the organization of applied agricultural research while preserving its unique possibilities. The results of this work enable, in the case of political will, the realization of greater efficiency of applied agricultural research established by the state in the Czech Republic.

The interrelationships between foreign direct investment and economic growth in Africa

Bolani, Lindelwa Mandisa January 2015 (has links)
There has been a long search for the keys to development and economic growth in Africa. This study investigates the relationship between FDI and economic growth over the period 2000-2012 using data from 48 African countries. On the aggregate regional level FDI and economic growth were found to be positively correlated during this period. Using panel data econometric techniques and the Panel Granger Causality test, results revealed that a bi-directional causality relationship existed between FDI and GDP. Thus, the results suggest that GDP is a requirement for increased investment, and at the same time is the result of increased foreign investment. Thus, the conclusion is that African policy makers are justified in increasing their attempts to create an attractive business environment for foreign investors, as it is beneficial for economic growth.

Interférométrie atomique avec un condensat de Bose-Eintein : effet des interactions internes / Atom interferometry with a Bose-Einstein condensate : effect of internal interactions

Jannin, Raphaël 08 October 2015 (has links)
Le travail réalisé dans le cadre de cette thèse s'articule en deux volets. Le premier porte sur l'étude de l'effet des interactions entre atomes au sein d'un interféromètre atomique, dont la source est un condensat de Bose-Eintein. Nous présentons un modèle analytiquepermettant d'obtenir des expressions simples pour le déphasage induit par celles-ci. Ce modèle est comparé à des simulations numériques résolvant les équations de Gross-Pitaevskii couplées, et présente un excellent accord. Le second concerne la conception et la construction d'un nouveau dispositif expérimental visant à obtenir un condensat de Bose-Einteindans le but de réaliser des mesures de haute précision par interférométrie atomique. / The work performed during this thesis comprises two orientations. The first one is the study of the effect of interactions between atoms in an atom interferometer which source of atoms is a Bose-Einstein condensate. We present an analytical model allowing to obtain simple expressions for the phase shift induced by them. This model is compared to numerical simulations solving the coupled Gross-Pitaevskii equations and presents a good agreement. The second one is the design and construction of a new experimental set-up for the production of a Bose-Einstein condensate to perform high precision measurements with the use of atom interferometry.

Odhad kapitálových služeb v České republice / Estimate of Capital Services in the Czech Republic

Hudrlíková, Lenka January 2009 (has links)
This diploma paper discusses the importance of implementation of capital into the system national accounts. The purpose of this work is an estimation of capital services for real data of the Czech Republic. Conducted its own calculation is first such comprehensive estimate of the capital services, which was made. The diploma paper is divided into three parts. In the first part there is a explaination of concept of capital services and the methods of estimation and possible ways of calculating the necessary data. In the second part there is already done my own calculations of estimate of capital services used the methodology recommended by the OECD, but subject to certain adjustments, which are better suited to national conditions. Due to the volume of data all the calculations are listed in the Annex. In the text work is illustrative example of one sector of economic activity and the economy as a whole. The last section deals with experimental estimates of impact of capital services on macroeconomic aggregates, particularly gross domestic product. Other possibilities obtained an estimate of capital services, it is possible to estimate multi-factor productivity. Capital services can be used to express the input of capital.

Konvergence evropských ekonomik v kontextu globální nerovnosti / Convergence of European economies in the context of global inequality

Kučerová, Michaela January 2009 (has links)
This thesis deals with the convergence of European economies in the context of the deepening global inequality in the world. The theoretical part discusses the concept of convergence and the basic theories of economic growth, explaining the convergence of economies to their steady state. This part also deals with global inequality. Different types of inequalities and methods of measurement are identified, with focus on external inequality measured by GDP per capita in purchasing power parity. The analytical part examines the development of gross domestic product of the analyzed economies. The regression analysis of beta convergence shows that the economies converge and that the inequality between them is decreasing. One part of the analytical section also clarifies the relationship between long-term growth and its determinants. The section is concluded with the regression analysis of dependence between the long-term growth and selected determinants. The analysis shows that the statistically significant main factors contributing to long-term growth in the analyzed economies are the level of investment, openness of the economy, and government capital expenditures. Foreign direct investment inflows are also an important determinant, but not statistically significant. On the other hand, long-term economic growth is negatively influenced by the rate of population growth.

Je superhrubá mzda skutečně superhrubý, světově nestandardní omyl? / Is Super-gross Wage Really Super-gross, World Nonstandard Mistake?

Braunová, Veronika January 2011 (has links)
Super-gross wage is a gross wage increased by social insurance contributions paid by the employer. Since its introduction in the Czech Republic its non-standard has been discussed. The theoretical part alerts that the logic of super-gross wage is indisputable because it reveals the total wage costs of the employer per employee, leads to higher transparency between the employee and the state and finally social insurance contribution is a benefit paid by the employer to employee which increase his welfare so it should enter the tax base. A gross wage widespread with any benefit or allowance paid by the employer is for the purposes of this thesis entitled as a "super-gross wage". Analysis of the personal income tax shows that super-gross wage is non-standard worldwide but not unique. "Super-gross wage" is on the other hand a standard method of taxation of personal income used in 45 % of analysed countries.
