When high degree of uncertainty is present, these tools can be used as strongly helpful advisors in the decision making process. Non-linear relations among variables are normally not captured in traditional linear econometric models. Moreover, specially on situation of crisis or rupture, linear relation do no represent anymore a good proxy to real behavior of financial-economical variables. This contributes for increasing the distance between the theoretical forecasting model and the real data. Throughout this work, we show a methodology for gathering and applying data into Bayesian Networks in order to obtain cash flow growing models for some Brazilian companies and the economical sector they play. Later on, we compare the results of such predictions to the traditional econometric models, and finally to the real data observed in such period. As a conclusion of the study, we make an evaluation of the pros and cons of using Bayesian Network for such application. / Redes Bayesianas podem ser ferramentas poderosas para construção de modelos econômico-financeiros utilizados para auxílio à tomada de decisão em situações que envolvam grau elevado de incerteza. Relações não-lineares entre variáveis não são capturadas em modelos econométricos lineares. Especialmente em momentos de crise ou de ruptura, relações lineares, em geral, não mais representam boa aproximação da realidade, contribuindo para aumentar a distância entre os modelos teóricos de previsão e dados reais. Neste trabalho, é apresentada uma metodologia para levantamento de dados e aplicação de Redes Bayesianas na obtenção de modelos de crescimento de fluxos de caixa de empresas brasileiras. Os resultados são comparados a modelos econométricos de regressão múltipla e finalmente comparados aos dados reais observados no período. O trabalho é concluído avaliando-se as vantagens de desvantagens da utilização das Redes de Bayes para esta aplicação.

Long interviews (McCracken, 1988) were conducted with 16 subjects, focusing on their personal history and experienced narratives are related to life and sports practice and consumption. Interviews were focused on subjects experiences with live and TV football watching experiences. The conceptual framework provided by Holbrook (1999) was used to identify consumer behavior; to describe the different forms of fruition and evaluation. Observations points to active participation in message building on the pitch with high leveIs of connotative content, contrasting with high denotative content on the TV messages, which stresses the didactical character of TV broadcastings. As the forms of presentation of the football spectacle can be seen as packets of information, we can bring to this analysis the ideas of Eco (2001). For Eco, the value of information is proportional to the richness of choices and possible meanings. Such approach is consistent with the proposition by Holbrook (1999) that the valuation of consumption experience is derived from interaction with the world. This way, the degree of interactivity is directly related to the volume of associative connotations preceded by the spectator. / A pesquisa procura estudar a forma como o espetáculo futebol é percebido e valorizado por espectadores no estádio e na televisão. O modelo proposto por Holbrook (1999) sustenta a análise de narrativas que relatam comportamentos dos consumidores nos dois ambientes: arquibancada e sofá. Com base na abordagem sugerida por McCracken (1988), os dados foram coletados por entrevistas pessoais, em profundidade, que possibilitaram explorar as experiências dos entrevistados como espectadores regulares de futebol na televisão e no estádio. Foram analisados os tipos de valor do modelo de Holbrook (1999) mais representativos encontrados nos relatos. As narrativas indicaram substantivas diferenças entre os valores percebidos ao longo das experiências na arquibancada e no sofá. Esta dualidade serviu de fio condutor para a emergência de outros duplos conceituais extraídos das entrevistas - que se revelam subsídios para o desenvolvimento de estratégias de marketing. Concluiu-se que a valorização da partida de futebol é influenciada pela forma com a qual o espectador constrói os significados na experiência de consumo. Percebeu-se, desta forma, uma associação entre a abordagem semiológica (Eco, 2001), para a qual o valor (da informação) decorre das possibilidades de significados possíveis; e a proposição de Holbrook, para o qual o valor de consumo se sustenta numa vivência interativa. Impõe-se ao gestor, portanto, a missão de executar a tabelinha sofá-arquibancada. De maneira a potencializar seus respectivos atributos para o consumo - como a riqueza simbólica e a riqueza referencial - e a reforçar os traços complementares apontados nas entrevistas.

A crescente competição entre empresas tem levado à busca da excelência em diversas áreas dentro das organizações. Assim, como o relacionamento da empresa com seus clientes é importante para os resultados desta, o relacionamento com seus fornecedores também se mostra vital. As empresas têm buscado um melhor desempenho de seus fornecedores, para estar mais bem preparadas para competir em seus mercados. Este trabalho discute a importância de compras e, principalmente, do papel decisivo que os fornecedores estão exercendo nas organizações, através de um estudo de caso. Também se busca analisar os quesitos adotados por uma empresa (modelo estudado) para medir o desempenho dos fornecedores em compras, de forma a tornar-se um referencial na tomada de decisões da empresa, de modo que esta possa melhorar seus indicadores quanto à performance de seus fornecedores. / The increasing competition between companies has led to the search of the excellency in various areas inside the organizations. As well as the relationship of the company with its customers it is important, for the results of the first, the relationship with its suppliers that also reveals vital. The companies have searched for one better performance of its suppliers, to be well prepared to compete in its markets. This work mainly argues the importance of purchases and of the decisive paper that the suppliers are exerting in the organizations. Also it searchs here to analyze the questions adopted for a company (model studied here) to measure the performance of the suppliers in purchases, in way that it can be a referencial for the taking of decisions on the part of the company, in way that this can improve its pointers to contribute to the performance of its suppliers.

This study is aimed at investigating the effect of mergers and acquisitions on the share prices and dividends involving South African companies in the food and beverage industry. A sample of 79 mergers from 1999 to 2005 was used. The data was analysed using the event study methodology and descriptive statistics. In addition, the paired t-test was also conducted to test the significance of the results. The results were presented using graphs, tables and charts. The results showed that target companies obtained negative abnormal returns during the announcement of mergers while acquiring companies on the other hand received positive abnormal returns. The results imply that it can no longer be generalized that target companies always win and acquiring companies lose during the merger activity. On the other hand, the dividends for target companies increased significantly after the merger, while the dividends for acquiring companies remained insignificantly negative after the merger. / Graduate School of Business Leadership / MBL

This thesis is a historical, sociological case-study of the movement for public control and land-use planning prior to WWII. The impetus for this movement came from a radicalized faction of the forestry profession. Radicalism in forestry centered around a group of professional foresters who were followers of Gifford Pinchot, the nation's Chief Forester from 1898-1910. Pinchot commenced the movement for public control over cutting on private forestlands in in the nineteen-teens. The emphasis in this case-study is on identifying social factors responsible for giving impetus to a movement for collective environmental planning, and the social and environmental possibilities of this subject. Three specific areas are studied: first radicalism in the forestry profession; second the vision of sustainability that emerged from radical forestry; and finally the relationship between the radical foresters and organized currents of the political Left. Findings: The understanding of the scientific conservation and land-use planning movement that has developed in scholarly literature does not provide an accurate characterization of this movement. The neglected vision of sustainability through public ownership and planning associated with radical forestry might be reconsidered in light of the present environmental problems. Despite the fact there was a radical presence in the forestry profession, norms of professional behavior are significant obstacles to radicalization, hence why Pinchotist conservation is anomalous in environmental history. Even though leading personalities in forestry took up the cause of public control, the institutional environmental movement remained aloof, giving indication that there are barriers to the development of an organized movement for environmental planning. Various radical political currents, however, demonstrated signs of receptivity to the scientific conservation movement.

Ações mitigadoras e compensatórias se fazem necessárias para que o desempenho da atividade de extração de areia seja sustentável. Nesse contexto, essa pesquisa teve como objetivo avaliar o perfil ambiental qualitativo das atividades de extração de areia em leitos de rios, a fim de mensurar os custos das externalidades negativas impostas ao meio ambiente e à sociedade que não são internalizados pelos agentes no mercado de areia. Especificamente, procurou-se: Caracterizar as principais externalidades ocorridas na extração da areia no leito do Rio Paraíba; Identificar os bens substitutos da areia dentro do processo de produção da indústria da construção civil; Determinar quanto à sociedade está disposta a pagar um valor a mais pelo metro cúbico de areia (DAP) para agregação dos benefícios ambientais do rio, através do método de valoração contingente (MVC) e Validar o método de valoração contingente, verificando o grau de veracidade dos resultados obtidos na pesquisa. Utilizou-se o método Check-list, como forma de identificar e enumerar sistematicamente as variáveis ambientais relevantes, a partir dos impactos ambientais observados. Após a avaliação, observou-se 30 impactos negativos e 4 impactos positivos, apontando para o fato de que as externalidades negativas detectadas sobrepõem-se, de forma relevante, às externalidades positivas, trazendo, assim, danos considerados tecnicamente irreversíveis ao meio ambiente e consequentes reflexos na sociedade. Para mensurar o valor econômico do recurso natural “areia” extraída dos leitos de rios, internalizando os custos via preço das externalidades provocadas ao meio ambiente decorrente da prática desse tipo de atividade, utilizou-se o Método de Valoração Contingente (MVC) a partir do modelo referendo com acompanhamento (logit duplo). A partir da agregação do valor encontrado para a DAP dos entrevistados e o consumo anual de areia na Paraíba, chega-se aos benefícios que o recurso natural “areia” pode gerar para o próprio rio. / Externalities caused by the activity of sand extraction in river beds have caused serious damage to the environment and society. Mitigating and compensatory actions are necessary so the performance of sand extraction activity would be sustainable. In this context, this research aimed to evaluate the qualitative environmental profile of activities of sand extraction in river beds in order to measure the costs of negative externalities imposed on the environment and society that are not internalized by the agents on the sand market. Specifically, it was sought to: characterize the main externalities occurring in the sand extraction in the bed of the Rio Paraiba; identify the goods substitutes for sand in the production process of the construction industry; Determinate how much society is willing to pay an additional value by cubic meter of sand (CMS) for aggregation of the environmental benefits of the river, through the contingent valuation method (CVM) and Validate the contingent valuation method, checking the degree of accuracy of results in research. The checklist method was used as a way to systematically identify and list the relevant environmental variables, from the environmental impacts observed. After evaluation, it was found 30 negative and four positive results, pointing to the fact that the negative externalities detected overlap relevantly to positive externalities, bringing thus considered technically irreversible damage to the environment and consequent reflections on society. To measure the economic value of natural resource "sand" extracted from the river beds, internalizing costs through price externalities caused to the environment resulting from the commission of such activity, the Contingent Valuation Method (CVM) from the referendum model with monitoring (double logit) was used. From the aggregation of the value found to the CMS of respondents and an annual consumption of sand in Paraíba, one comes to the benefits that the natural resource "sand" can lead to the river itself.

The University is inserted and is determined by economic, political and cultural interests defined by the dichotomy of the social force’s play. In this analytic line, I’ve assumed that the public University still is the major locus for training of professionals, considering its dimensions of social institution and of public nature. I approach especially the public university as a space for training, considering his proposal to train teachers in their undergraduate programs in order to meet the demands of a democratic state, young and lacking qualified professional to work in education: the state of Tocantins. We decided, me and my advisor, as a method the historical-critical dialect, seeking to explain social transformations based on a historical analysis of society and their method of permanent movement, and also with a more qualitative than quantitative of the available materials research (theory and research), properly systematized, following the methodology of content analysis. The result of empirical research conducted with a group of teachers and students participating in the project “Construindo Saberes: o ensino por projetos nas licenciaturas”* reveals that the Prodocência fulfills its function in a scenario where there was not, so far, a specific program for teaching incentive by funding agencies associated with the Ministry of Education. However, by the discourse of the subjects involved, we clearly see that the project's actions underscored the importance of more research than the act of teaching itself. / O propósito desta pesquisa, que ora se configura nesta dissertação, é estudar e analisar o “Programa Consolidação das Licenciaturas – Prodocência”, no âmbito de politica de educação e mais especificamente o projeto “Construindo Saberes: o ensino por projetos nas licenciaturas”, proposta institucional da Universidade Federal do Tocantins – UFT, financiado com recursos do Prodocência, visando à melhoria da formação nos cursos de licenciatura no âmbito das universidades públicas. A Universidade está inserida e é determinada por interesses econômicos, políticos e culturais definidos pela dicotomia do jogo de forças sociais. Nesta linha analítica assumi que a Universidade pública ainda é o principal locus de formação dos profissionais considerando a sua dimensão de instituição social e de natureza pública. De modo especial enfoquei a Universidade pública, como espaço de formação, considerando sua proposta de formar professores nos seus cursos de licenciatura com intuito de atender às demandas de um Estado democrático jovem e carente de profissionais qualificados para atuar na educação: o estado do Tocantins. Optamos, eu e minha orientadora, como método, o histórico- crítico e dialético, procurando explicar as transformações sociais com base em uma leitura histórica da sociedade e seu modo de fundamento em permanente movimento, e também fazendo uma análise mais qualitativa do que quantitativa dos materiais disponíveis (teóricos e da pesquisa), devidamente sistematizado, seguindo a metodologia de Analise de Conteúdo. O resultado da investigação empírica, realizada com um grupo de professores e alunos participantes do projeto “Construindo Saberes: o ensino por projetos nas licenciaturas” revela que o Prodocência cumpre a sua função em um cenário onde não havia, até então, nenhum programa específico de incentivo à docência por parte dos órgãos de fomento ligados ao Ministério da Educação. Porém, no discurso dos atores envolvidos, percebemos claramente que as ações do projeto ressaltaram mais a importância da pesquisa do que o ato docente em si.

Analysts, investors and entrepreneurs have recognized the value of personal data for Internet economics. Personal data is viewed as the "oil" of the digital economy. Yet, ordinary people are barely aware of this. Marketers collect personal data at minimal cost in exchange for free services. But will this be possible in the long term, especially in the face of privacy concerns? Little is known about how users really value their personal data. In this paper, we build a user-centered value theory for personal data. On the basis of a survey experiment with 1269 Facebook users, we identify core constructs that drive the value of volunteered personal data. We find that privacy concerns are less influential than expected and influence data value mainly when people become aware of data markets. In fact, the consciousness of data being a tradable asset is the single most influential factor driving willingness-to-pay for data. Furthermore, we find that people build a sense of psychological ownership for their data and hence value it more. Finally, our value theory helps to unveil market design mechanisms that will influence how personal data markets thrive: First, we observe a majority of users become reactant if they are consciously deprived of control over their personal data; many drop out of the market. We therefore advice companies to consider user-centered data control tools to have them participate in personal data markets. Second, we find that in order to create scarcity in the market, centralized IT architectures (reducing multiple data copies) may be beneficial.

O presente trabalho realizou uma aplicação empírica do modelo de Ohlson (1995) para as principais empresas brasileiras listadas na BM&FBovespa no período de 1996 a 2010, buscando verificar a consistência do modelo na previsão dos preços das ações. Dado que o método para utilização deste modelo é divergente na literatura, para este estudo decidiu-se pela metodologia de dados em painel, a qual considera tanto as características individuais de cada empresa, quanto à fatores específicos de determinados períodos. Foram desenvolvidos dois testes empíricos para o modelo, um para a função de preço e outro para a função de retorno. Os resultados encontrados mostraram que o modelo foi rejeitado no mercado de capitais brasileiro para as duas funções. / This paper conducted an empirical application of the Ohlson model (1995) for the main Brazilian companies listed on the BM&FBovespa in the period 1996-2010, in order to verify the consistency of the model in predicting stock prices. Since the method for using this model is divergent in the literature, it was decided the use of panel data methodology for this study, which considers both, the individual characteristics of each company and the specific factors for certain periods. It was developed two empirical tests for the model, one for the price function and another for the return function. The results showed that the model was rejected in the Brazilian capital market for both functions.

The theme of this thesis is ?The development of metodology valuation of flats?. Its aim is to monitor and evaluating the development of prices by regulations. The first part of this thesis describes basic definitions relating to the valuation of flats explain the concepts of price and value and the methods that are used in the valuation of flats. In a separate chapter I focused on the wording of the laws and regulations in the valuation. In practical part I appraised flat using program Delta-NEM working with regulations available in this program. There were used comparative and expense methods. In the last part is shown progressive evolution of prices model and used flat using graphs and made comparsion prices progression of these two flats.
