Realidade socioeconômica e ambiental de um agrupamento de bairros da zona norte de Teresina, Piauí /Cunha, Paulo Borges da. January 2010 (has links)
Orientador: Manuel Rolando Berrios Godoy / Banca: Silvia Aparecida Guarnieri Ortigoza / Banca: Maria Juraci Zani dos Santos / Banca: Agostinho Paula Brito Cavalcanti / Banca: Lindon Fonseca Matias / Resumo: Os fenômenos de crescimento urbano desordenado das grandes cidades brasileiras trouxeram consigo uma série de problemas que sacrificam a saúde e o conforto dos seus habitantes. Para tanto, torna-se necessário o conhecimento evolutivo do assentamento humano nas áreas urbanas, para que se possa fazer um planejamento e gestão ambiental e, assim, proporcionar um conforto melhor para os seus habitantes, sem causar grandes impactos ao meio ambiente. Este trabalho tem como objetivo analisar as realidades socioeconômica e ambiental no arranjo espacial do "mosaico ocupacional" da zona norte de Teresina, Piauí, onde estão inseridos os bairros de Matadouro, Matinha, Pirajá e Vila Operária. Para tentar vislumbrar a realidade socioeconômica e ambiental dos bairros pesquisados, o estudo utilizou a metodologia de Kawakubo, Luchiari e Morato (2005), aplicada à realidade da área de estudo, no que concerne à mensuração da qualidade ambiental urbana, a partir de dados disponibilizados pelo IBGE (2000), e se fundamenta na elaboração de índices dos temas: domicílios improvisados, áreas verdes, esgotamento sanitário, abastecimento de água e coleta de lixo, e na construção de um índice sintético, o Índice de Qualidade Ambiental Urbana. Para verificar o contraste entre os bairros, com relação às percepções dos moradores sobre a estrutura urbana da região, foi aplicado o teste Estatístico Qui-quadrado, utilizandose as frequências absolutas das respostas do questionário. Ressalte-se que a realidade é dinâmica e contraditória e as transformações são rápidas, apesar de, em muitas ocasiões, não haver percepção de forma imediata / Abstract: The phenomenon of the disorderly urban sprawl of big cities has brought a series of problems that sacrifices the health and comfort of its inhabitants. That is why it becomes necessary to know the evolutionary human settlement in urban areas, so you can make an environmental planning and management, and thus provide a better comfort for its inhabitants without causing major impacts to the environment. This paper aims to analyze the socioeconomic and environmental realities in the spatial arrangement of the "occupational mosaic" of the northern part of Teresina, Piauí, where the neighborhoods of Matadouro, Matinha, Pirajá and Vila Operária are located. In order to try to catch a glimpse of the environmental and socioeconomic reality of the neighborhoods surveyed, the methodology of Kawakubo, Luchiari and Morato (2005) was used, applied to the reality of the study area regarding the measurement of urban environmental quality, from data provided by IBGE (2000), and it is based on the development of indexes of subjects (improvised homes, green areas, sewage, water supply and garbage collection) and the construction of a synthetic indicator, the Urban Environmental Quality Index. To see the contrast between the districts regarding the perceptions of residents on the urban structure of the region, we applied the Chi-square statistic test using the absolute frequencies of the answers from the questionnaires. We emphasize that the reality is dynamic and contradictory and the changes are fast, although in many occasions, there is no immediate perception / Doutor

ESSAYS ON MIGRATION AND HUMAN CAPITAL ACCUMULATIONXu, Xu 01 May 2014 (has links)
The first essay is The linkage between foreign direct investment and international migration. Immigration policy and policies regarding the flow of capital across borders are generally enacted separately. Such separation may not be appropriate if there are interactions between immigration and foreign direct investment (FDI). Although much research has focused on the determinants of international migration, little agreement has been made with respect to how FDI affects migration. In this paper, we attempt to clarify the influence of FDI on migration. We consider not only how aggregate FDI into country i affects migration from i to j but also how the FDI that i receives specifically from country j (which we denote as bilateral FDI) affects migration from i to j. We find that bilateral FDI stock has a positive and significant impact on the size of migrant stock through what we call an ``ideological linkage". We show that this finding is robust across different estimation methods, including instrumental variables Tobit and Heckman selection models. We conclude that the influence of FDI on migration needs to be considered when designing economic policies. The second essay is Environmental quality and international migration. This essay examines the extent of which pollution is a factor that pushes people to migrate across borders. It provides an empirical analysis of the aspects of air quality and its unexplored role in the international migration. We allow pollution to affect migrants differently according to their gender and educational attainment. We also consider different types of air pollution such as sulfur dioxide and particulate matter. We then test for the interaction between environmental quality and income upon migration. We find that air pollution is a push factor but not necessarily for countries with very high incomes. We also find evidence supporting that there is a gender difference in the migration-environment association. Finally, the third essay is The effects of foreign universities on domestic human capital accumulation. In this essay, we focus on the impact of foreign direct investment in education (i.e., foreign universities opening up branches overseas) on human capital formation in the host countries. High ranking universities have the privilege to enter foreign market and usually enjoy subsidy from the host country. However, the entry of low quality foreign universities may have positive impact on domestic human capital accumulation with less uncertainty. In our model, we have three types of universities: high quality foreign universities located domestically, low quality foreign universities located domestically and domestic universities. Agents in the model represent students in the host country who decide upon their level of preparedness for a university education. As comparative statics exercises, we examine how effort changes when the slots of high quality or low quality foreign institutions change. Results from these comparative statics exercises could help a government choose the optimal size of high quality or low quality foreign universities where optimal means maximizing aggregate effort. We also examine the effect of foreign education premium on human capital accumulation. To the best of our knowledge, this is the first economics-based, theoretical study of this issue. We conclude that the entry of low quality foreign universities generally increases domestic human capital accumulation whereas allowing more high quality universities to enter the country produces less straightforward results. We also find that lowering the wage gap could have beneficial effects on human capital accumulation.

Copper and zinc speciation in the Tamar EstuaryPearson, Holly Beverley Clare January 2017 (has links)
The chemical speciation of trace metals controls their potential bioavailability and therefore toxicity to exposed organisms. Despite previous studies demonstrating the ameliorative effects of dissolved organic carbon (DOC) on metal toxicity, the effectiveness of ligands from varying sources and of potentially variable composition in controlling speciation has not been studied in detail in estuarine waters. In addition, the effect of DOC on radionuclide contaminants in combination with trace metals has not been investigated in any waters. This is of particular interest in the estuarine environment, where both anthropogenic and natural ligands, and contaminants that pose a potential threat to ecosystem health, can be present. Competitive ligand exchange adsorptive cathodic stripping voltammetry (CLE-AdCSV) with complexation capacity titrations was employed to determine the speciation of dissolved Cu and Zn, two metals that possess revised environmental quality standards (EQS) which now account for potential metal bioavailability. Dissolved metal concentrations in the < 0.4 and < 0.2 μm filter fractions of samples from the Tamar Estuary were determined during seasonal transects made over a calendar year. Samples were taken over a full salinity range (0-35) and from locations thought to contain DOC from a variety of sources (e.g. terrigenous, biogenic, sewage). No seasonal trends in metal speciation were identified, but a semi-quantitative assessment of DOC type using 3-D fluorimetry showed domination of humic and fulvic type ligands in the upper estuary, and biogenic-type ligands in the lower estuary, the former appearing the most important in controlling Cu and Zn complexation. Filter size fraction differences showed a major portion of the dissolved metal is associated with the 0.2 ≥ 0.4 μm fraction, indicating an importance of larger molecule ligands in controlling potentially bioavailable metal. Sample ligand concentrations ([L_x]) ranged from 1-372 nM (Cu) and 3-412 nM (Zn), and metal-ligand conditional stability constants (log K_(ML_x )) from 10.5-13.5 (Cu) and 7.5-10 (Zn), which are similar to reported literature. Calculated free metal ion concentrations ([M2+]) of 0.3 – 109 nM (Zn) and 1.4 x 10-13 – 7.3 x 10-11 M (Cu) compared well (92% showed no significant differences (P = 0.02)) with direct measurements of [Zn2+] made for the first time in estuarine waters using “Absence of Gradients and Nernst Equilibrium Stripping” (AGNES) after optimisation for estuarine waters. AGNES fully complements CLE-AdCSV in terms of analytical capability and shows that methods are now available that are capable of directly determining [Zn2+] in estuarine waters for use in environmental monitoring studies. Calculations made using the chemical equilibrium speciation programme Visual MINTEQ (VM) showed [Cu2+] and [Zn2+] could be predicted to within one order of magnitude of measured values when log K_(ML_x ) and [L_x] are determined and input into the model. This was in contrast to poor agreement between measured and predicted [M2+] when VM was used with the NICA-Donnan complexing model, which assumes a set portion of the total DOC concentration input is fulvic acid that actively complexes metals. These results corroborate a lack of identification of a relationship between metal speciation in the Tamar samples and DOC concentration, highlighting that knowledge of DOC type, log K_(ML_x )and L_x are important when assessing environmental risk, setting EQSs and for accurate modeling of [Cu2+]. Finally, a combined chemical and biological study investigating the effects of mixtures of DOC, Zn and the radionuclide tritium (3H) on the marine mussel presents the first evidence of a protective effect of Zn on DNA damage caused by 3H. The association of 3H with DOC remains elusive and an assessment of DOC type is recommended for future research, but the study emphasises the importance of investigating mixture effects in order to avoid inaccurate risk assessment and potentially costly site remediation.

Variação temporal da comunidade zooplantônica em arroios impactados por mineração na bacia hidrográfica do Arroio Candiota, RS, BrasilFernandes, André Pereira Teixeira January 2017 (has links)
A bacia hidrográfica do Arroio Candiota está situada no sudoeste do Estado do Rio Grande do Sul, Brasil. Sofre intensa atividade antrópica, como mineração de carvão e calcário, pecuária, silvicultura e agricultura. Apresenta ainda em seu território a Usina Termelétrica Presidente Médici - UTPM - Candiota II. Este trabalho teve como objetivo analisar a variação temporal da comunidade zooplanctônica, representada por Rotifera, Cladocera e Copepoda, a partir das variáveis ambientais e atributos funcionais em alguns arroios impactados pelos diferentes usos da bacia hidrográfica do Arroio Candiota. Foram realizadas coletas trimestrais de água e zooplâncton com o intuito de caracterizar as estações climáticas do ano, durante o período de abril/2007 a outubro/2014. As coletas ocorreram em sete estações amostrais diferentes, totalizando 161 unidades amostrais. As variáveis físicas e químicas selecionadas para este trabalho foram pH, turbidez, ferro dissolvido, oxigênio dissolvido e temperatura. Para as análises estatísticas foram utilizados modelos lineares generalizados (GLM), cálculo da diversidade das espécies, que envolveu duas medidas baseadas em distâncias topológicas, a distinção taxonômica (Δ*) e a diversidade taxonômica (Δ), análise de espécies indicadoras (ISA) e análise de atributos indicadores (ITA). Foram identificados 152 táxons ao total das coletas. Rotifera foi predominante com 122 espécies, após Cladocera com 16 espécies e Copepoda com 14 espécies. Os resultados mostraram que o pH foi a única variável que apresentou resultado significativo com valores positivamente proporcionais para a abundância de espécies. Em relação à riqueza de espécies, as variáveis pH, ferro dissolvido e oxigênio dissolvido influenciaram positivamente ao longo do tempo. O cálculo da diversidade e distinção taxonômica demonstrou que das 161 unidades amostrais, 127 mostraram valores de diversidade conforme o esperado ao acaso na natureza. Quatro unidades amostrais apresentaram valores da diversidade acima do esperado e 31 exibiram valores abaixo do esperado ao acaso. A ISA identificou duas espécies indicadoras da estação amostral 1 e cinco espécies indicadoras da estação amostral 2. Foram encontradas cinco espécies indicadoras específicas do inverno, cinco do outono, quatro da primavera e nove espécies indicadoras no verão. A ITA demonstrou que espécies de tamanho C4 (≥ 1000 μm), tiveram maior ocorrência no inverno e primavera. O atributo funcional “coletores e raspadores” foi considerado indicador para as estações amostrais EA1 e EA3 por cinco espécies. Os resultados encontrados não demonstraram um gradiente contínuo de crescimento ou declínio da abundância e riqueza de espécies ao longo do tempo. Assim, a comunidade zooplanctônica parece ser mais fortemente influenciada pelas características naturais de Candiota, como relevo e rede de drenagem, com exceção dos riachos que recebem diretamente efluentes da mineração de carvão. / The Arroio Candiota watershed is located in the southwestern state of Rio Grande do Sul, Brazil. It suffers intense human activity, such as mining of coal and limestone, livestock, forestry and agriculture. It also presents in its territory the Thermoelectric Plant Presidente Medici - UTPM - Candiota II. This study aimed to analyze the temporal variation of zooplankton community, represented by Rotifers, Cladocera and Copepoda, from the environmental variables and functional attributes in some streams impacted by different uses of the Arroio Candiota watershed. Quarterly sampling of water and zooplankton were conducted in order to characterize the seasons of the year, during the period April/2007 to October/2014. The collections occurred in seven different sampling stations, totaling 161 sampling units. The physical and chemical variables selected for this study were pH, turbidity, dissolved iron, dissolved oxygen and temperature. For statistical analysis we used generalized linear models (GLM), calculating the diversity of species, which involved two measures based on topological distances, the taxonomic distinction (Δ*) and taxonomic diversity (Δ), indicator species analysis (ISA) and indicators atributes analysis (ITA). There were identified 152 taxa to the total collections. Rotifera was predominant with 122 species, 16 species of Cladocera and 14 species of Copepoda. The results showed that pH was the only variable that showed significant results with positive values proportional to the abundance of species. The variables pH, dissolved iron and dissolved oxygen positively influenced the richness of species over time. The calculation of diversity and taxonomic distinction showed that of the 161 sampling units, 127 showed diversity of values as expected at random in nature. Four sampling campaigns showed values of diversity than expected and 31 showed values lower than expected by chance. The ISA has identified two indicator species of the sampling station 1 and 5 indicator species of sampling station 2. We found five specific indicator winter species, five in autumn, four in spring and nine summer indicator species. The ITA has shown that species of C4 size (≥ 1000 μm), were more frequent in winter and spring. The functional attribute "collectors and scrapers" was considered indicator for the sampling stations 1 and 3 with five species. The results did not demonstrate a continuous gradient of growth or decline in abundance and species richness over time. Thus, the zooplankton community seems to be more strongly influenced by Candiota natural features like topography and drainage network, except for streams that receive wastewater directly from coal mining.

Esta bacia recebe água de pequenos e médios afluentes que cortam várias cidades de porte diversificado, com e sem tratamento e efluentes domésticos e industriais. Além disso, banha uma extensa área com atividade pecuária e agrícola com usinas sucro energéticas e frigoríficos. Com esta bacia recebe afluentes de diversas áreas, está sujeito à contaminação de diversas fontes. Uma dessas fontes que gera preocupação à população e ao poder público é a que está relacionada com os sedimentos por metais tóxicos e potencialmente tóxicos. Dentro desse contexto, este trabalho verificou a qualidade da água e dos sedimentos no rio Tietê entre as barragens Promissão e Ibitinga. Os pontos de retirada de material para análise no reservatório foram localizados próximos às margens e a jusante dos afluentes selecionados, próximos à barragem de Promissão, resultando em sete pontos de amostragem. A primeira coleta ocorreu no mês de setembro e a segunda em dezembro de 2013. Analisaram-se doze metais na água e no sedimento bem como dez parâmetros físico-químicos na água. A técnica utilizada para análise de metais foi a espectrofotometria de absorção atômica. Resultados das análises de sedimento mostraram, que em todas as amostragens notou-se a presença sistemática dos elementos Fe, Al, Mg e Cr, com maiores concentrações nos pontos referentes ao córrego Barra Mansa e ao rio Dourado. Este último apresentou-se como área vulnerável e a contaminação devido às concetrações obtidas em todos os elementos analisados.

This watershed receives small and medium tributaries that pass through several cities of diverse size, with and without treatment of domestic and industrial sewage water. In addition, an extensive bathing area with farming agriculture, alcohol plants, and frigorific. As this wathershed receives tributaries from different areas, is subject to contamination from various sources. One such source that creates concern for the people and the government is related to the sediments by toxic and potentially toxic metals. In this sense, this study analyzed the quality of water and sediment in the Tietê River between Promissão and Ibitinga dams. The collections points of material for analysis were located near the stores and downstream of selected tributaries, closely to dam Promissão, resulting in seven sampling. The first collection occurred in September and the second in December 2013. Twelve metals in water and sediment were anlyzed as well like ten physico-chemical parameters in water. The technique used for metal analysis was by atomic absorption spectrophotometry. Results of analyzes of sediment showed, for instance, that in all samplings noted the systematic presence of Fe, Al, Mg and Cr, with higher concentrations in the points related to stream Barra Mansa and Rio Dourado. The latter appeared as a critical area of contamination due to concentrations from all elements analyzed. The results of metals in sediments were compared with the concentrations found in studies conducted by Braz (2006), which analyzes made in two periods, February and July 2000, conducted by Mortatti (2010) in Barra Bonita reservoir, which held sediment samples from March to June 2004. The use of pesticides is a factor that potentially has an effect on the accumulation of heavy metals in...

Evaluating the Performance of Leadership in Energy and Environmental Design (LEED) Certified Facilities using Data-Driven Predictive Models for Energy and Occupant Satisfaction with Indoor Environmental Quality (IEQ)January 2015 (has links)
abstract: Given the importance of buildings as major consumers of resources worldwide, several organizations are working avidly to ensure the negative impacts of buildings are minimized. The U.S. Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) rating system is one such effort to recognize buildings that are designed to achieve a superior performance in several areas including energy consumption and indoor environmental quality (IEQ). The primary objectives of this study are to investigate the performance of LEED certified facilities in terms of energy consumption and occupant satisfaction with IEQ, and introduce a framework to assess the performance of LEED certified buildings.
This thesis attempts to achieve the research objectives by examining the LEED certified buildings on the Arizona State University (ASU) campus in Tempe, AZ, from two complementary perspectives: the Macro-level and the Micro-level. Heating, cooling, and electricity data were collected from the LEED-certified buildings on campus, and their energy use intensity was calculated in order to investigate the buildings' actual energy performance. Additionally, IEQ occupant satisfaction surveys were used to investigate users' satisfaction with the space layout, space furniture, thermal comfort, indoor air quality, lighting level, acoustic quality, water efficiency, cleanliness and maintenance of the facilities they occupy.
From a Macro-level perspective, the results suggest ASU LEED buildings consume less energy than regional counterparts, and exhibit higher occupant satisfaction than national counterparts. The occupant satisfaction results are in line with the literature on LEED buildings, whereas the energy results contribute to the inconclusive body of knowledge on energy performance improvements linked to LEED certification. From a Micro-level perspective, data analysis suggest an inconsistency between the LEED points earned for the Energy & Atmosphere and IEQ categories, on one hand, and the respective levels of energy consumption and occupant satisfaction on the other hand. Accordingly, this study showcases the variation in the performance results when approached from different perspectives. This contribution highlights the need to consider the Macro-level and Micro-level assessments in tandem, and assess LEED building performance from these two distinct but complementary perspectives in order to develop a more comprehensive understanding of the actual building performance. / Dissertation/Thesis / Masters Thesis Engineering 2015

As doenças, principalmente as infecto-contagiosas, atualmente, se configuram em um excelente parâmetro para a investigação da qualidade ambiental e de vida urbana. As doenças transmissíveis, apesar de serem amplamente conhecidas, controladas e prevenidas, ainda causam altos índices de morbidade e de mortalidade e retratam a pobreza social, tecnológica e econômica, bem como o descaso político. A dengue, uma doença transmissível, reapareceu no espaço urbano devido a vários fatores sócio-ambientais, destaca-se: a falta de saneamento, o baixo nível educacional, fatores comportamentais, econômicos, culturais e falta de políticas públicas. No que diz respeito aos fatores ambientais destaca-se o clima, pois as temperaturas elevadas e as precipitações abundantes favorecem o desenvolvimento de vetores que, conseqüentemente, elevam o risco de doenças infecciosas. Desse modo, a presente investigação de mestrado buscou analisar as relações existentes entre o (re)aparecimento da Dengue e alterações socioambientais que ocorreram no espaço urbano de Piracicaba-SP, visando contribuir com as políticas públicas locais.
