O conhecimento do impacto da variação na demanda final da agropecuária na geração de produto, emprego e importações reveste-se de grande relevância para o desenvolvimento econômico do Ceará. Este trabalho tem como objetivo geral analisar o impacto da política de investimentos na agropecuária sobre os demais setores da economia cearense, utilizando como instrumental analítico a teoria de insumo-produto. As conclusões apontam a importância da agropecuária para a economia do Estado em termos de geração de produto e de emprego, chamando a atenção para o caráter multiplicador da expansão dos investimentos voltados para este macro setor. Quanto às importações, observou-se elevada capacidade de geração de importações por parte da economia do Ceará, a partir dos investimentos aplicados na agropecuária, podendo representar um indício da fragilidade da estrutura produtiva cearense para fornecer insumos necessários à realização do seu processo produtivo. Ademais, a dependência de insumos importados pode ser prejudicial à expansão da agropecuária, caso a competitividade de seus produtos seja afetada negativamente. Por outro lado, o mesmo resultado pode representar oportunidades de negócios a serem aproveitadas, com a verticalização da produção. Para que a agropecuária cearense cumpra seu papel como indutora do desenvolvimento econômico, é imprescindível uma remodelação das políticas agrícolas vigentes.

Makes an analysis considering the household income concept aplied for brasilian states. Besides a large preliminary discussion concerning partial factors who explain inequality, including those ones assign to national literature, this thesis presents two relevant parts. The characterization of probability distribution that describe income distribution for brasilian states and a different methodology to calculate inequality and poverty indicators. Concerning this goal are present two information groups: Kernel Functions and “best adjustment” probability distributions for every state. By the way, are presents two theoretical structure, from result different econometrics framework, on the way to explain income inequality in Brazil. Thus, to catch the relationship between household income inequality and economic growth, was used first a framework based upon a simultaneous equation models applied in cross-sectional data for brazilian states with some extensions to different revenue percentiles. Otherwise, considering a theoretical model with just one equation and following panel data methodology to Random Effects and Instrumental Variables estimation. At the and was made an exercise using Quantiles Regressions to catch the selected variables effects on different groups of states.

This Thesis studies three distinct problems between itself, even so connected for the instrument. In the first chapter a model of endogenous technical progress is used to study the relations between growth of the agricultural productivity and the process of industrialization in a context of open economy. The concept of Dynamic Comparative Advantage is exhaustingly used and, additionally, searchs to understand as the technological integration between the sectors agricultural and industrial contributed for the dynamics of the employ in the industry. In the second chapter a model of general equilibrium was used to analyze and to compare the effect of two fiscal adjustment rules: the rule of primary superávit proportional to the product and the rule of zero nominal deficit . In the constructed model the rules it was analyzed the impacts of these rules on the optimal allocations as well as on the welfare. In both the cases, the effect of short and long runs always are compared. Finally, the third chapter considers an alternative proofs of the Hotelling´s Lemma and Shephard´s Lemma using new relations of duality in the theory of the production. The proofs proposals possess two advantages, relatively to the usual demonstrations, which are, not the use of the known Enveolpe Theorem and the validity of the demonstration for interior points to the production set.

With the increasing population and urbanization process of the management of water resources has become increasingly complex. Among the sectors of economy, agriculture is what consumes most water, using approximately 70% of global reserves of water. In this study we attempt to find an interface between the agro-industrial system and water resources in semiarid northeastern to have a more efficient and participatory management of water. Based on the literature review conducted it was concluded that to promote more efficient management of water, facing the enormous pressures and demands of the agribusiness northeast, you must redefine the legal- institutional process based on the principles of decentralized, participatory and systemic, and the watershed as the unit of planning and management and water as a public good which has economic value.

A utilização de tecnologia na agricultura a torna menos dependente dos fatores climáticos, mais produtiva e promissora, contribuindo para a obtenção do seu desenvolvimento e da economia. Os investimentos em tecnologia para a agricultura,realizados pelo Governo do Estado do Ceará, concentram-se principalmente na agricultura irrigada através da formação de agropolos. Nesses, predomina a fruticultura irrigada, sendo a banana uma das principais culturas. A bananicultura desempenha importantes papéis de ordem econômica e social para a agricultura brasileira, entretanto é caracterizada pela prática, em geral, com baixa produtividade, baixo nível tecnológico e grandes perdas no processo de produção. No agropolo Cariri a bananicultura tem ganhado relevância com o aumento considerável da área plantada e da quantidade produzida. Nesse agropolo, o crescimento da cultura deu-se com maior intensidade no Município de Mauriti. O objetivo deste trabalho foi estudar o nível tecnológico da bananicultura irrigada do Município de Mauriti-CE e seus aspectos socioeconômicos. Especificamente pretendeu-se mensurar o nível tecnológico, verificar as tecnologias que têm maior contribuição na determinação desse nível tecnológico e os fatores socioeconômicos que condicionam sua adotação pelos produtores de banana de Mauriti- CE. Para mensuração do nível tecnológico, foi formulado um índice que compreende não somente as tecnologias de produção, mas também as variáveis que a compõem. A análise das variáveis socioeconômicas dos produtores que têm efeito sobre a probabilidade de adoção de tecnologia deu-se através da estimação de uma equação, utilizando o modelo Probit, indicado para estudos em que a variável dependente é qualitativa. O índice tecnológico calculado para a bananicultura de Mauriti mostrou que o nível tecnológico adotado é classificado como bom. As tecnologias de irrigação e fitossanidade têm nível de adoção classificado como ótimo e as tecnologias de mudas, adubação e tratos culturais, como de nível bom. Por outro lado, os níveis de adoçãos das tecnologias de colheita e pós-colheita são classificados como regulares e o da gestão como insuficiente. Na composição do índice tecnológico, a fitossanidade teve participação de 21,15%, a irrigação de 19,23% e os tratos culturais de 15,38%. As tecnologias de mudas e adubação tiveram participação de 13,46% e 11,54%, respectivamente. As menores participações foram das tecnologias de pós-colheita, com 9,61%, de colheita com 7,69%, e da gestão, com 1,92%. As variáveis que se mostraram significativas na explicação da probabilidade de adoção de tecnologia adequada ou próxima de adequada para produção de banana foram assistência técnica, bananicultura como atividade principal, crédito, escolaridade, idade, posse da terra, renda total e residência na propriedade. Todas essas variáveis mostraram ter influência positiva sobre tal probabilidade

This paper analyzes the situation of supply of drinking water for residents in the seats of municipalities in Ceará with minor and major and HDI, respectively, with higher and lower rates of growth in that index. The main objective of this analysis is to identify the main contrass and similarities between the municipalities regarding the conditions of supply of drinking water, especially with regard to the current bid; critical levels of supplies, and investments in the secto. Data were collected by the National Water Agency (ANA). Based on the results obtained it was concluded that in municipalities with the highest HDI: have a greater expectation of meeting the water supply for the year 2015; there is a better distribution of water sources; the management systems of water supply is more decentralized; and, there is a lower frequency of conflicts over water use. In all districts examined, however, themain cause of conflicts over water use is the silting of water sources, mainly from the reservoirs.

Algumas transformações ocorridas na década de 1990, como a reestruturação do mercado, a megametropolização, a globalização e abertura econômica, a evolução da tecnologia da informação, assim como a dificuldade intrínseca para a produção agropecuária e geração de emprego e renda levam os produtores a buscar opções de produção voltadas para hortigranjeiros e caprino-ovinocultura, originando o surgimento de novos arranjos produtivos. O estudo de arranjos produtivos locais é importante, pois as micro e pequenas empresas necessitam, cada vez mais, de procedimentos que levem em consideração aspectos como a inovação, interação, cooperação, aprendizagem e articulação de configurações institucionais, proporcionando, assim, a inserção e o desenvolvimento dessas empresas no mercado competitivo e globalizado. Diante do exposto, o presente trabalho objetiva conhecer as características de inserção e as possibilidades de desenvolvimento dos pequenos, médios e grandes produtores do arranjo produtivo local voltados para a caprino-ovinocultura nos Municípios de Quixadá e Quixeramobim, no Estado do Ceará. Os dados de natureza primária foram coletados por meio de entrevistas e pesquisa direta, tendo como instrumentos questionários, aplicados com a 70 caprino-ovinocultores e instituições locais no arranjo. Utilizou-se o processo de amostragem probabilística do tipo aleatório simples. A análise e a interpretação dos dados foram efetuadas de acordo com o método descritivo e com a técnica de análise tabular. Identificou-se o fato de que a caprino-ovinocultura é desenvolvida na grande maioria por jovens criadores com níveis de escolaridade considerados baixos, que tinham seus pais como precursores da atividade. A maior parte das pequenas e médias empresas foi criada recentemente, ou seja, da década de 1990 até 2003. Já as grandes empresas apresentam maior tempo de vida, e suas direções foram passadas ao longo de gerações (pai para filho). Quanto à evolução, as empresas apresentam uma tendência de crescimento de faturamento total e médio no período compreendido entre 1990 e 2002. Os produtores desenvolveram diversas atividades inovadoras voltadas principalmente para melhoramento genético de animais e participaram ativamente de processos de aprendizado e cooperação com outros produtores e agentes locais. O arranjo apresenta grandes potencialidades que contribuem para o desenvolvimento da atividade, além da participação ativa de programas específicos voltados para a caprino-ovinocultura.

This paper falls into two distinct but clearly inter-related parts. In the first, a summary is provided of the basic figurational findings which show how the ‘Association’ or ‘soccer’ form of football developed first of all in England in the nineteenth century. Basically what is show is how status rivalry led to the emergence in that context of the soccer and Rugby games, both of which were then beginning to become more ‘civilized’ than their medieval antecedents. In that context, a summary is provided of the core features of Elias’s sometimes misunderstood theory of civilising processes’. The paper ends with a figurational examination and diagnosis of ‘football’ or ‘soccer hooliganism’, a problem which is still sometimes falsely represented as ‘the English disease’ but has now become a problem which is literally world-wide in scope.

The aim of the paper is to articulate defensible principles that should govern the internal management of a football team. Here we seek to balance the prevailing trend by means of a reflection of moral lines that interweaves political virtues such as equality and respect for personal autonomy with a distributive pattern that takes into account the physical abilities and the parameters of excellence internal to football.

This work is part of the dissertation “The Meanings of the Amateur Soccer of Recife from its interdependence with the Professional Soccer”. Here, we reflect on the amateurism and professionalism as directions of the sportivization process and taking the amateur soccer as inquiry object, we analise the singularity of this social figuration and its relations in the Recife city. Underlie this work the Elias figurational sociology, the Bourdieu´s notion of field and historical studies about sports and football.

This paper aims to evaluate the capacity of payment, under risk conditions, of the bulk water to the rural producers’ users in Jaguaribe basin, State of Ceará. It was considered the aspects concerning whether the irrigation system is public or private, the location of the irrigation district, the level of consumption level and the activities being carried out. The data are primary, gathered by the application of 93 questionnaires to producers in private and public irrigation districts. As method of analysis, it is used the Monte Carlo Simulation. We can conclude that for the sample of public and private irrigation farmers, the capacity of payment (CP) for bulk water shows a negative average value and that the majority of these producers cannot afford to pay for the water use, which represents high risk for the activities carried out. Only the irrigation farmers that showed net income (residual or net-back), under deterministic conditions, higher than zero, can pay with large margin or low risk the value of tariff being charged currently by the water governmental agency (Cogerh). Some irrigation farmers do not show any probability of paying the current tariff. The public irrigation farmers show higher CP relatively the private ones. The cattle-raising activity was the one that showed lower risk concerning the tariff charged.

This study aims to make the economic assessment of five Desali-nation Systems by Reverse Osmosis (RO) that are used to generate fresh water for human consumption in rural communities in the Ceará State. The data was gathered from primary source by questionnaire applied to governmental organizations. The method used was the analysis of investment taking into account shadow prices. We concluded that due to the inexistence of any good practices for the desalination management some equipment resulted in negative financing return when considering the efective consumption, particularly those of 400 and 600 liter/hour. In adition, they generated inefficiency regarding to technical support, turning impossible better improvement of the system performance, thus leading to insecure water supplies and unsatisfied demand. Given the limitations imposed by the managers, low production and system failures, which re- sulted in constant systems’ interruption, the effective demand of fresh water was restricted to the half of the working capacity of the system.

In studying the possibility of increasing wireless system capacity, we evaluate the performance of some algorithms that make use of sub-space techniques to estimate the covariance matrix, and compare these results to those obtained through traditional methods, such as the Direct Matrix Inversion -Maximum Signal-to-Noise Ratio and Maximal Ratio Combining. Illustrative simulation results demonstrate that the Minimum Mean Square Error - signal Sub-Space and the Weighted Sub-Space algorithms may lead to a better performance than fullrank conventional algorithms. Furthermore, a more elaborate system-level simulation in a TDMA IS-136 context is performed and it shows that such benefits also appear in a more practical scenario.

This study represents an attempt to evaluate the current criteria for the distribution and setting of the price of irrigation water. The study focuses the determination of the efficient price for water. Curently, the government allocates water based on average consumption per hectare, and the water price is set with the objective of recovering the costs of supplying it. There is no exclusive use ofwater. Crop income and the willingness of the producer to pay for water are not considered in the current allocation system. The model proposed in this study is based on short-term water demand curves derived from crop production functions for the 1995/96 crop year. The results demonstrate that 36,6 % of the irrigation water was not allocated to high value crops. If each cropped received the optimum quantity of water, the gross value of production would increase significantly. The revenue generated from paying for the water would more than cover the operation and maintenance costs of the water supply system.

The irrigated fruit cultivation is an activity that has been growing in the State of Ceará, mainly in certain favourable areas. Among these areas, there is the Low Jaguaribe, where various enterprises explore the activity. To evaluate, therefore, whether the irrigated fruit cultivation developed in the region has been contributing for the sustainable development, this research tried to evaluate the social and environmental aspects of the activity. The social matters were evaluated through interviews with the workers of the enterprises that produce fruits in the region. Were interviewed people who worked directly in the production (cultivation, harvest and after harvest cares) because these are the majority of workers in these enterprises. The interviews included items such as: education and health public services in the municipalities of residence, housing, sanitary aspects, possession of lasting consumer goods and job. The environmental matters of the activity were evaluated through interviews with the responsible technicians in the enterprises visited. Items such as use of soil conservation practices, existence of legal reserve in the property, plagues and illnesses control, fire use in the agricultural activity, kind of irrigation system used, among others, were included in the interviews. Starting from these information, two indexes were calculated: one of workers’ quality of life and another of environmental viability. Starting from these two indexes, it was obtained an index of socio-environmental viability of the irrigated fruit cultivation in the region’s enterprises visited in the region as environmental and socially viable.
