Qualidade de vida em Porto Velho, Rondônia: perspectivas do processo de desenvolvimento regional

Esta tese de doutorado nasceu da escassez de estudos referentes aos efeitos das grandes obras, sobre a qualidade de vida das cidades. Nesse sentido, visando estudar exatamente esse problema dentro de um cenário amazônico, propôs-se pesquisar os efeitos das usinas hidrelétricas de Jirau e de Santo Antônio, em seu processo de construção, às margens do rio Madeira, em Rondônia e, assim, analisar a qualidade de vida dentro do perímetro urbano da cidade de Porto Velho, o que constituiu o objeto de estudo da presente investigação. Para tanto, buscou-se aporte na teoria do “Fetiche”, de Marx, na obra “O capital” (1980). Assim, procurou-se explicar a migração de trabalhadores, na busca por melhores salários e oportunidades de ganhos econômicos, nas obras das hidrelétricas mencionadas. A perspectiva teórica do “fetichismo da mercadoria”, de Marx (1967), desencadeou a inter-relação com os aspectos diretamente ligados ao âmago da presente tese, que se constitui numa Pesquisa de natureza qualitativa. Essa foi desenvolvida com base no método de Análise Fatorial, utilizando o programa estatístico SPSS, versão 17. Para isso, foram aplicados 1.449 questionários, distribuídos igualitariamente, em grupos de 21, para cada um dos 69 bairros da cidade. E, dessa forma, construir os índices de IQVU (índices de qualidade de vida urbana), segundo Santos e Martins (2002) e, para análises multifatoriais, de acordo com Hair et al. (2005) e com Santana (2007; 2005). A partir disso, os resultados obtidos permitiram concluir que o índice de qualidade de vida de Porto Velho, no período correspondente à fase anterior a chegada das usinas, à região, era de 0,452. Portanto, classificado como um índice de desempenho regular. Em relação à fase atual, esse índice apresentou uma queda de 15,31%, alcançando um valor de 0,392. Por consequência, considerado de ruim desempenho. Desse modo, permitiu-se concluir que a qualidade de vida de Porto Velho, conforme a opinião dos entrevistados, literalmente, piorou com a chegada das usinas hidrelétricas do rio Madeira, em Porto Velho/Rondônia. A relevância do presente estudo reside na análise do espaço intramunicipal e na integração dos dados provenientes da pesquisa de campo, com a informação gerada durante as análises. Isto levou a deduções lógicas, fundamentadas nos critérios adotados e decorrentes dos resultados das avaliações. Consequentemente, esse poderá servir como suporte às decisões políticas, sobre o planejamento de ações a serem executadas, para gestão do território no âmbito municipal.

Competitividade inter-regional de sistemas de produção de bovinocultura de corte

O trabalho apresenta uma metodologia de avaliação de sistemas de produção através da mensuração da competitividade interna na bovinocultura de corte. Durante o primeiro trimestre de 2010, foram aplicados 65 questionários com pecuaristas, sendo 36 entrevistas na Região Sul (Estado do Rio Grande do Sul) e 29 na Região Norte (Estados do Pará e Rondônia). Foram definidos os principais direcionadores que afetam a competitividade interna - tecnologia, gestão, relações de mercado e ambiente institucional, sendo atribuído um peso específico para cada direcionador, a fim de obter o índice de competitividade. Os resultados foram analisados estatisticamente pela teoria de resposta ao item e pela análise de correspondência (ANACOR) com o software SPSS®. A Região Sul apresentou uma maior competitividade que a Região Norte. Independente da região, os fatores críticos de competitividade foram: integração lavoura-pecuária, planejamento estratégico, cálculo de indicadores financeiros, formação de preços, acesso a inovações tecnológicas e organização dos produtores.

SOCIAL POLICY AS REGIONAL POLICY: MARKET AND NONMARKET FACTORS DETERMINING REGIONAL INEQUALITY

We decompose the recent changes in regional inequality in Brazil into its components, highlighting the role of spatially blind social programs. We aggregate personal income micro data to the state level, differentiating nine income sources, and assess the role of these components in the observed changes in regional inequality indicators. The main results indicate that the largest part of the recent reduction in regional inequality is related to the dynamics of the market-related labor income, with manufacturing and services favoring deconcentration. Labor income in agriculture, retirement and pensions, and property rents and other sources favored concentration. The social programs Bolsa Familia and Beneficios de Prestacao Continuada are responsible for more than 24 percent of the reduction in inequality, although they account for less than 1.7 percent of the disposable household income. Such positive impact on regional concentration is impressive, since the goals of the programs are clearly nonspatial.

Guidelines for the Brazilian ceramic sector strategic development, based on a comparison with the Italian market

Based on a structured literature review, the ceramic tiles sector of Italy (benchmark) and Brazil (2nd world producer and consumer) are compared, under four strategic factors: normative, market, technology and strategic management, in order to identify critical risks for a national strategic sector. The document aims to propose guidelines for a strategic re-planning of the Brazilian ceramic tiles sector, making the Brazilian producers aware of the national market fragility (in spite of its recent remarkable evolution) and helping the policy makers to reflect on the need of reviewing the strategic planning methods and practice, of designing new targeted programs (based on coherence between operation and business strategies), of providing improved management to strengthen the sector against unfair competition by low-cost producers, enhancing the necessary infrastructure in technology, work, marketing and quality management. The analysis is limited to the single-firing production technology. The wide-coverage strategic analysis of the Brazilian ceramic tiles sector, very little studied until now in a scientific way, emphasizes the importance of applying research methodology and may be valuable to both scholars and practitioners. Additionally, it highlights the need of investments in innovation (product design and production technology) and the fundamental role of the sector organization, identifying different dimensions. It is possible to conclude that the recent Brazilian production growth is not due to a natural strengthening because of the hit of the sector and of correct enterprises strategy, but it seems the result of a temporary and favorable economic contingency.

Urban food planning, city logistics and sustainability: the role of the wholesale produce market. The cases of Parma and Bologna food hubs.

At global level, the population is increasingly concentrating in the cities. In Europe, around 75% of the population lives in urban areas and, according to the European Environmental Agency (2010), urban population is foreseen to increase up to 80 % by 2020. At the same time, the quality of life in the cities is declining and urban pollution keeps increasing in terms of carbon dioxide (CO2) emissions, waste, noise, and lack of greenery. Many of European cities struggle to cope with social, economic and environmental problems resulting from pressures such as overcrowding or decline, social inequity, health problems related to food security and pollution. Nowadays local authorities try to solve these problems related to the environmental sustainability through various urban logistics measures, which directly and indirectly affect the urban food supply system, thus an integrated approach including freight transport and food provisioning policies issues is needed. This research centres on the urban food transport system and its impact on the city environmental sustainability. The main question that drives the research analysis is "How the urban food distribution system affects the ecological sustainability in modern cities?" The research analyses the city logistics project for food transport implemented in Parma, Italy, by the wholesale produce market. The case study investigates the renewed role of the wholesale market in the urban food supply chain as commercial and logistic operator, referring to the concept of food hub. Then, a preliminary analysis on the urban food transport for the city of Bologna is presented. The research aims at suggesting a methodological framework to estimate the urban food demand, the urban food supply and to assess the urban food transport performance, in order to identify external costs indicators that help policymakers in evaluating the environmental sustainability of different logistics measures

Fault delineation and stress orientations from the analysis of background, low magnitude seismicity in Southern Apennines (Italy)

The aim of this work was to show that refined analyses of background, low magnitude seismicity allow to delineate the main active faults and to accurately estimate the directions of the regional tectonic stress that characterize the Southern Apennines (Italy), a structurally complex area with high seismic potential. Thanks the presence in the area of an integrated dense and wide dynamic network, was possible to analyzed an high quality microearthquake data-set consisting of 1312 events that occurred from August 2005 to April 2011 by integrating the data recorded at 42 seismic stations of various networks. The refined seismicity location and focal mechanisms well delineate a system of NW-SE striking normal faults along the Apenninic chain and an approximately E-W oriented, strike-slip fault, transversely cutting the belt. The seismicity along the chain does not occur on a single fault but in a volume, delimited by the faults activated during the 1980 Irpinia M 6.9 earthquake, on sub-parallel predominant normal faults. Results show that the recent low magnitude earthquakes belongs to the background seismicity and they are likely generated along the major fault segments activated during the most recent earthquakes, suggesting that they are still active today thirty years after the mainshock occurrences. In this sense, this study gives a new perspective to the application of the high quality records of low magnitude background seismicity for the identification and characterization of active fault systems. The analysis of the stress tensor inversion provides two equivalent models to explain the microearthquake generation along both the NW-SE striking normal faults and the E- W oriented fault with a dominant dextral strike-slip motion, but having different geological interpretations. We suggest that the NW-SE-striking Africa-Eurasia convergence acts in the background of all these structures, playing a primary and unifying role in the seismotectonics of the whole region.
