Die ökonomischen Studien V. K. Dmitrievs, Ein Beitrag zur Interpretation und theoriehistorischen Würdigung unter besonderer Berücksichtigung der russischen Volkswirtschaftslehre

Schütte, Frank 01 September 2003 (has links)
Gegenstand der Arbeit ist das Leben sowie das Werk des ersten russischen mathematischen Ökonomen Vladimir Karpovic Dmitriev (1868-1913). Es werden alle bekannten Schriften Dmitrievs vorgestellt und eine Einführung und Interpretation seines wirtschaftstheoretischen Hauptwerkes, den „Ökonomischen Essays“ (1898/1902), angeboten. Daneben erfolgt eine Beschreibung seiner Stellung innerhalb der russischen Nationalökonomie sowie eine Würdigung im Kontext der westlichen Volkswirtschaftslehre. Dabei werden die bis dato zu Dmitriev gewonnenen Erkenntnisse integriert, vertieft und kritisch hinterfragt. Auskünfte zur russischen Geschichte sowie die Erläuterung landestypischer Begriffe erleichtern das Verständnis der Dmitriev’schen Positionen. Es zeigt sich, dass Dmitriev allen gesundheitlichen und materiellen Widrigkeiten zum Trotz eine beachtliche wissenschaftliche Leistung vollbrachte: Er gelangte zu Erkenntnissen, die seiner Zeit um Jahrzehnte voraus waren und deren Relevanz bis in die Gegenwart reicht. Nicht nur trug er zu einem verbesserten Verständnis der klassischen Theorie bei und nahm damit einige Elemente der Forschung in den 1950/60er Jahren vorweg, Pionierleistungen erbrachte er ebenfalls für die Input-Output-Analyse sowie auf dem Gebiet der unvollkommenen Konkurrenz.

Dynamical probabilistic graphical models applied to physiological condition monitoring

Georgatzis, Konstantinos January 2017 (has links)
Intensive Care Units (ICUs) host patients in critical condition who are being monitored by sensors which measure their vital signs. These vital signs carry information about a patient’s physiology and can have a very rich structure at fine resolution levels. The task of analysing these biosignals for the purposes of monitoring a patient’s physiology is referred to as physiological condition monitoring. Physiological condition monitoring of patients in ICUs is of critical importance as their health is subject to a number of events of interest. For the purposes of this thesis, the overall task of physiological condition monitoring is decomposed into the sub-tasks of modelling a patient’s physiology a) under the effect of physiological or artifactual events and b) under the effect of drug administration. The first sub-task is concerned with modelling artifact (such as the taking of blood samples, suction events etc.), and physiological episodes (such as bradycardia), while the second sub-task is focussed on modelling the effect of drug administration on a patient’s physiology. The first contribution of this thesis is the formulation, development and validation of the Discriminative Switching Linear Dynamical System (DSLDS) for the first sub-task. The DSLDS is a discriminative model which identifies the state-of-health of a patient given their observed vital signs using a discriminative probabilistic classifier, and then infers their underlying physiological values conditioned on this status. It is demonstrated on two real-world datasets that the DSLDS is able to outperform an alternative, generative approach in most cases of interest, and that an a-mixture of the two models achieves higher performance than either of the two models separately. The second contribution of this thesis is the formulation, development and validation of the Input-Output Non-Linear Dynamical System (IO-NLDS) for the second sub-task. The IO-NLDS is a non-linear dynamical system for modelling the effect of drug infusions on the vital signs of patients. More specifically, in this thesis the focus is on modelling the effect of the widely used anaesthetic drug Propofol on a patient’s monitored depth of anaesthesia and haemodynamics. A comparison of the IO-NLDS with a model derived from the Pharmacokinetics/Pharmacodynamics (PK/PD) literature on a real-world dataset shows that significant improvements in predictive performance can be provided without requiring the incorporation of expert physiological knowledge.

A indústria moveleira de Boa Vista : estrutura e potencialidades

Souza, Luciana Silva de January 2009 (has links)
O objetivo desta dissertação foi avaliar a estrutura e as potencialidades da indústria moveleira do Município de Boa Vista (Roraima). Para a obtenção dos dados, foram aplicados questionários a empresas filiadas ao Sindicato das Indústrias de Marcenaria do Estado de Roraima – SINDIMAR; de um total de 19 empresas, 15 responderam aos questionários, representando 78,9% da amostra. Procurou-se levantar dados de forma simplificada, mas que retratassem a real situação do setor. Além desses dados, se obteve outros de fontes secundárias e de estudos empíricos anteriores sobre o setor, além daqueles fornecidos por instituições como SEBRAE. A idéia foi efetuar sugestões visando o aumento da competitividade do setor, através de melhorias nas matérias-primas, mão-de-obra, tecnologia e design, para agregar maior valor ao produto final. A revisão da literatura focou a teoria da localização, a teoria dos pólos de crescimento e a teoria do desenvolvimento local endógeno, centrada no papel das inovações e dos atores locais. Ao visitar as empresas, procurou-se detectar suas deficiências e potencialidades. Com o diagnóstico da situação atual do setor, se identificou os fatores de seu sucesso e os que vêm dificultando o seu avanço, com o objetivo de motivar os empresários a investir nessa atividade. Constatou-se que a matéria-prima utilizada é oriunda de outros municípios do Estado de Roraima e que cerca de 80% da produção é destinado ao próprio Município de Boa Vista, enquanto que os outros 20% destina-se a outros municípios do Estado. Concluiu-se que o setor moveleiro de Boa Vista necessita de muitas melhorias, tanto no plano tecnológico, com máquinas mais modernas, como do ponto de vista de gestão e logística. As principais dificuldades enfrentadas pelo setor são a carência de mão-de-obra qualificada, a falta de capital de giro para investir em equipamentos apropriados, já que a produção é feita na maior parte de forma semi-artesanal, entre outros fatores. Nesse sentido, o setor necessita de mais apoio de órgãos oficiais de assistência e de crédito, a fim de promover o desenvolvimento do setor, independentemente do porte das empresas. / The objective of this study was to evaluate the structure and the potential of the furniture industry of the City of Boa Vista (Roraima). To attain the data, member companies of the Union of the Woodwork and Furniture Industries of the State of Roraima - SINDIMAR were given questionnaires; of a total of 19 companies, 15 answered and returned the questionnaires, representing 78.9% of the sample. The objective was to get data in a simplified form, but which portrayed the real situation of the sector. Besides the data obtained from the questionnaires, other secondary sources and previous empirical studies on the sector, was used as well as the data supplied by institutions such as SEBRAE. The idea was to effect suggestions aiming at the increase of the competitiveness of the sector, through improvements in the raw materials, man power and workmanship, technology and design, to add greater value to the final product. The revision of literature focused on the theory of the location, the theory of the growth in industrial poles and the theory of the endogenous local development, centered on the role of innovation and local actors. When visiting the companies, researchers sought to detect their deficiencies and potentialities. With the diagnosis of the current situation of the sector, the factors of success and the impairments that make it difficult to advance were identified, with the objective of motivating entrepreneurs to invest in this activity. Evidence shows that the raw material used is sourced from other cities within the State of Roraima and that about 80% of the production is destined to the very City of Boa Vista, while the other 20% goes to the other cities of the State. It was concluded that the woodwork and furniture sector of Boa Vista is in great need of improvement, as much in the technological field, with more modern machines, as in the area of logistic and management. The main difficulties faced by the sector are the lack of qualified labor, the lack of capital to invest in appropriate equipment, since the production is done for the most part on a half-artisan basis. With this in consideration, the sector needs more support from official agencies of assistance and credit, in order to promote the development of the sector, independent of the size of the companies.

ANÁLISE INTERSETORIAL DOS FLUXOS DE ÁGUA VIRTUAL PARA A ECONOMIA BRASILEIRA: UMA ABORDAGEM INSUMOPRODUTO / INTERSECTORAL ANALYSIS OF VIRTUAL WATER FLOWS IN THE BRAZILIAN ECONOMY: AN INPUT-OUTPUT APPROACH

Moraes, Vanessa de Oliveira 09 April 2015 (has links)
Conselho Nacional de Desenvolvimento Científico e Tecnológico / Water is a major input used directly and indirectly by the different sectors of the economy to produce goods and services. The use of this resource as a productive input is known as virtual water. This concept was developed by Allan (1993) and it refers to the water that is embedded or embodied in the production of agricultural commodities and industrial goods. The aim of this study is to apply an environmental input-output model to analyze water use in the Brazilian economy as well as to quantify the virtual water content in Brazil's imports and exports. The results indicate that Agriculture is an important key-sector, since, through the analysis of the matrix of coefficients transaction, it is possible to verify that it does mostly push the indirect water consumption of the majority of sectors. As for international trade of water resources, it comes out that Brazil is a net exporter of virtual water and that the largest share of exports is carried out by Food and Beverages sector and by Agriculture. Results suggest that Brazil is a virtual water net exporter, and most of the exports are made by Food and Beverage industries and Agriculture. These results reinforce the need to consider environmental costs that are inherent to trade goods in the use of water resources and a better management of water under scarcity conditions. / A água é um insumo importantíssimo utilizado direta e indiretamente pelos diferentes setores da economia na produção de bens e serviços. Ao uso desse recurso como insumo produtivo dá-se o nome de água virtual. Esse conceito foi desenvolvido por Allan (1993) e se refere a água que é embutida ou incorporada na produção de commodities agropecuárias e produtos industriais. O objetivo desse estudo é aplicar o método insumo-produto ambiental para analisar o uso da água na economia brasileira e mensurar o conteúdo de água virtual importado e exportado pelo Brasil. Os resultados indicam que a Agricultura é um importante setor-chave, já que, através da análise da matriz de coeficientes de transação, é possível verificar que o consumo indireto de água da maior parte dos setores é impulsionado principalmente pela agricultura. Em relação ao comércio internacional de recursos hídricos, tem-se que o Brasil é um exportador líquido de água virtual, sendo a maioria das exportações realizadas pelos setores de Alimentos e Bebidas e da Agricultura. Esses resultados reforçam a necessidade de considerar os custos ambientais intrínsecos ao comércio de bens intensivos no uso de recursos hídricos e o melhor gerenciamento da água em condições de escassez.

No. of bitstreams: 1 arquivototal.pdf: 822142 bytes, checksum: 70627e6205ffe1543bf344518400aca3 (MD5) Previous issue date: 2012-06-28 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Despite the inequality in income distribution of the Brazilian population come down over time, Brazil also has one of the worst income distributions in the world, especially when taking into account other countries with similar levels of development. In this context, is the Northeast, which has the highest income inequality and where the concentration of income has been falling more slowly compared to the rest of Brazil. An improvement exacerbated indicators such as poverty and income distribution may be related to economic structure, so that not all sections of the population to benefit from the fruits produced by an increase in income or economic growth. That is, trade flows, the sectoral structure of employment and production, the technology standard, the structure of consumption, and others may influence the effects caused by changes in the economy on indicators such as inequality. Accordingly, this study aims to assess how the economic structure of the Northeast region influences the effects of changes in the local economy on inequality, using the model of Leontief-Miyazawa. For this, were used information contained in the input-output matrix of the Northeast for the year 2004, the primary data of the Survey by Household Sampling - PNAD 2004, addition to the data from the Household Budget Survey - POF, using the structure of POF 2002/2003. Through simulations of impacts in each sector of economic activity was obtained the distribution of income provided for that impact and, consequently, the sectors responsible for the increase or reduction of inequality. Through the results it was found that only nine sectors improved the Gini index and the sectors with the greatest weight in the consumption of the poorest families contributed to a greater concentration of income after the impact. Moreover, was made an analysis of the effects of changes in production structure in the Northeast between 1997 and 2004 about the income distribution. For this, we used data from the input-output matrix of the Northeast in 1997 and household income data obtained by PNAD, referring to the same year. The results indicate that the lower income classes generate more income in the economy as a whole and absorb less. Finally, it was observed that changes in the productive structure occurred between 1997 and 2004 helped to improve the income distribution in the Northeast. / Apesar da desigualdade na distribuição de renda da população brasileira vir caindo ao longo do tempo, o Brasil possui ainda uma das piores distribuições de renda do mundo, principalmente quando se leva em conta outros países com níveis de desenvolvimento semelhantes. Neste contexto, encontra-se a região Nordeste, que possui a desigualdade de renda mais elevada e onde a concentração de renda vem caindo mais lentamente, quando comparada ao restante do Brasil. Uma melhoria mais exacerbada de indicadores tais como de pobreza e de distribuição de renda pode está relacionada à estrutura econômica, fazendo com que nem todas as camadas da população se beneficiem dos frutos gerados por um aumento de renda ou pelo crescimento econômico. Ou seja, os fluxos comerciais, a estrutura setorial do emprego e da produção, o padrão de tecnologia, a estrutura do consumo, entre outros podem influenciar os efeitos causados por mudanças na economia sobre indicadores, como de desigualdade. Nesse sentido, o presente trabalho pretende avaliar como a estrutura econômica da região Nordeste influencia os efeitos de mudanças na economia local sobre a desigualdade, utilizando o modelo de Leontief-Miyazawa. Para isto, foram utilizadas informações contidas na matriz de insumo-produto do Nordeste referente ao ano de 2004, os dados primários da Pesquisa por Amostra de Domicílios PNAD 2004, além dos dados da Pesquisa de Orçamento Familiar POF, sendo utilizada a estrutura da POF 2002/2003. Por meio de simulações de impactos em cada setor de atividade econômica obteve-se a distribuição de renda proporcionada por aquele impacto e, consequentemente, os setores responsáveis pelo aumento ou redução da desigualdade. Por meio dos resultados obteve-se que somente nove setores melhoraram o índice de Gini e os setores com maior peso no consumo das familias mais pobres contribuíram para uma maior concentração de renda após o impacto. Além disso, foi feita uma análise dos efeitos das mudanças na estrutura produtiva do Nordeste entre 1997 e 2004 sobre a distribuição de renda. Para isto, foram utilizados os dados da matriz de insumo-produto do Nordeste de 1997 e os dados dos rendimentos das famílias obtidos pela PNAD, referente ao mesmo ano. Os resultados apontam que as menores classes de renda geram mais renda na economia como um todo e absorvem menos. Finalmente, observou-se que as mudanças na estrutura produtiva verificada entre 1997 e 2004 contribuíram para melhorar a distribuição de renda no Nordeste.
