Despite theoretical and policy advancements in global human and gendered approaches to development, youth in mainstream development policy discourse remains subsumed. The ratification of global best practice models of human development in Nigeria, without contextualizing the probable dividends of youth capability strength in shaping national development realities, will present challenges that are likely to threaten the sustainable future of country. Perhaps if this is sustained, this thesis argues that the capabilities of Nigerian youths will continue to remain trapped or mismatched in areas that they fail to contribute positively to Nigeria's national development. In this regard, this thesis evaluated the extent to which youth capabilities are enhanced in the National Youth Service Corps (NYSC) for national development in Nigeria. Firstly, this thesis contributes conceptually to understanding, broadly, the social constructions of youth in mainstream policy discourse and their positioning in both global and national development practice in Nigeria. It also critically examines through literature how western epistemological interpretations of development theorizing are reproduced in youth discourse. Succinctly, the theoretical contribution of youth in development explains how development-underdevelopment dualism in mainstream development reproduces similar youth-adult dualisms in conceptualizing how youths are recognized, represented and constituted within policy discourses. Based on this, the theoretical gaps that this thesis bridges, operationalizes the Sen's capability approach (SCA) through the utilization of Narayan-Parker's empowerment framework in order to contextualize how the intersections of youth agency and structural contributions of the NYSC could aid the effective utilization of youth capabilities for national development in Nigeria. Secondly, this thesis contributes methodologically to development practice as it adapts a mixed-method approach (MMA) to researching youth lives, especially from a developing country's context. The application of a qualitative dominant mixed method approach (qual-MMA), suggests how through social constructivist ontology and through poststructuralist epistemology, the understanding of how youths socially construct their identity and the roles they play in national development becomes clearer. Thirdly, the germane and empirical contribution of this thesis especially to mainstream development theorizing is that, youth voices captured through narratives and quantitative data helped explore the experiences of Nigerian youth's transition pathways from education to the NYSC pathway. This further allowed for critical examination of how youths are: absorbed through mobilization into the NYSC; developed through the activities in the scheme; deployed and utilized in addressing national development challenges in Nigeria. This thesis suggests that dominant social constructions based on age and transition patterns, undermine the impact/effective functioning of youth capabilities for addressing national development challenges. It concludes that limited support structures during the youth educational pathways and lack of opportunity structures while youths are in the NYSC pathways continue to limit the functioning of their capabilities in sectors of national development needs. It recommends a need to rethink the current deployment strategy of the NYSC so that youth capabilities fit the national development narrative.

No contexto atual global, as ações humanas que visam à sustentabilidade são práticas necessárias. A sociedade urbanizada e industrializada necessita encontrar maneiras de mitigar os impactos ambientais negativos de seu (des)envolvimento, em especial, quanto à questão urgente dos resíduos sólidos. Apesar de uma gama de legislações estarem vigentes no Brasil, a prática delas ainda é escassa. A Zona Costeira é sensivelmente mais afetada pelo problema da falta de destinos aos resíduos sólidos produzidos. Além disso, a característica geográfica, geológica e geomorfológica dessa área a torna mais vulnerável à ocupação massiva e a conflitos de uso versus sensibilidade ambiental. No estado do Rio Grande do Sul, o setor Norte do litoral já pode ser considerado uma conurbação. Além disso, o aumento da taxa de geração de resíduos sólidos é maior do que o aumento do crescimento da população nesses locais. Tendo em vista tais aspectos, o objetivo deste trabalho é avaliar a viabilidade técnica e ambiental para a implementação de Centros de Compostagem no município de Imbé, localizado na Microrregião do Litoral Norte do Rio Grande do Sul, com base em dados ambientais, legais e de percepção ambiental da comunidade local, para selecionar/sugerir áreas passíveis de instalação dos pátios de compostagem. Para que os Centros de Compostagem sejam funcionais, é necessária a inserção do Consumo Reverso no Plano Municipal de Gestão Integrada dos Resíduos Sólidos, PMGIRS. As justificativas para selecionar locais aptos à instalação de Centros de Compostagem são, além de criar espaços para a educação ambiental, viabilizar uma alternativa para a gestão e o gerenciamento dos resíduos sólidos orgânicos, priorizando a redução do desperdício, pela valorização dos resíduos orgânicos, transformando-os em produto(s) para plantio. A metodologia utilizou dados pré-existentes para a matriz de dados, posteriormente integrando dados de campo na elaboração dos mapas, sintetizados na etapa de laboratório. Os parâmetros foram: uso e ocupação, características socioeconômicas, relevo/topografia, solo/drenagem, Áreas de Proteção Permanente, vegetação, risco de alagamento/inundação e vazios urbanos. A etapa de campo tratou da aplicação de entrevistas expositivas com questionário estruturado, contendo questões abertas, fechadas e de múltipla escolha à comunidade do Imbé, com registros fotográficos das áreas passíveis de proposição. O processamento de laboratório contou com o uso do Sistema de Informação Geográfica - SIG, para a elaboração de mapas temáticos com limite da área urbanizada, de vegetação, das Áreas de Proteção Permanente, de recursos hídricos e o mapa síntese, contemplando também os vazios urbanos para construção do Zoneamento Ambiental (ZA). O banco de dados gerado pelas entrevistas sofreu análise estatística através do QUI², balizando a percepção da população pelos Centros de Compostagem e o hábito em relação aos resíduos sólidos urbanos. Os resultados obtidos pelo mapa síntese, pela matriz de dados e pela análise estatística geraram um modelo de classificação a cada parâmetro, para aferição de áreas potenciais ao recebimento do Centro de Compostagem. Foram sugeridos os seguintes critérios: Ideal; Bom (com restrições); Ruim (com muitas restrições) e Inadequado. A pesquisa a partir de questionário mostrou que se confirma a hipótese de que os veranistas, moradores, comunidade do Ceclimar são favoráveis ao uso dos Centros de Compostagem. Os resultados criam um espaço para além da reciclagem, incluindo o envolvimento da comunidade local em ações com base na qualidade ambiental, Permacultura, Economia Solidária, na geração de renda e multiplicação para as residências domésticas. A pesquisa se embasou nas normas técnicas sobre a Política dos Resíduos Sólidos pela responsabilidade de consumo que possibilitará locais favoráveis à compostagem pública. pública. / The current global context for human actions aimed at sustainability are necessary practices. Urban and industrialized society needs to find ways to mitigate the form of their (un) involvement to reduce the environmental impacts of their actions. An urgent question is that of solid waste. Although a range of good laws are in force in Brazil, their practice is still scarce. The Coastal Zone is significantly more affected by this, its geographic, geological and geomorphological characteristic making it vulnerable to massive occupation and conflicts of use versus environmental sensitivity. In the state of Rio Grande do Sul the northern sector of the coast is already a conurbation. However, the increase in the rate of solid waste generation is greater than the increase in population growth. The objective of this work is to evaluate the technical viability for the implementation of composting centers in the municipality of Imbé, located in the Microregion of the Northern Coast of Rio Grande do Sul, based on environmental, legal and environmental perceptions of the local community, to select / suggest areas amenable to installation of composting yards. In order for the composting centers to be functional, it is necessary to insert the Reverse Consumption in the Municipal Plan for the Integrated Management of Solid Waste, PMGIRS. The justifications for selecting sites suitable for the installation of Composting Centers are to favor a viable alternative for the management and management of organic solid waste, with priority being given to waste reduction, by the valorization of organic waste, transforming them into agricultural product. And, also, create spaces for environmental education. The methodology, in the laboratory, used pre-existing data in the characterization of use and occupation, socioeconomic characteristics, relief / topography, soil / drainage, permanent protection areas, vegetation and flood / flood risk, based on preexisting mapping and analysis of the legal framework. The field stage dealt with the application of expository interviews with a structured questionnaire containing open, closed and multiple choice questions to the Imbé community, with photographic records of the areas that could be proposed. The field stage dealt with the application of expository interviews with a structured questionnaire containing open, closed and multiple choice questions to the Imbé community, with photographic records of the areas that could be proposed. The laboratory processing was based on the use of the Geographic Information System (GIS) for the elaboration of thematic maps with limits of the urbanized area, vegetation, APPs and water resources, and the synthesis map also contemplating the urban voids for the construction of the Environmental Zoning (ZA). The database generated by the interviews was analyzed statistically through the QUI², indicating the perception of the population by the composting centers and the habit in relation to solid urban waste.The results obtained by the synthesis map, by the data matrix and by the statistical analysis generated a classification model for each parameter for measuring potential areas to receive the composting center and suggested the following criteria: Ideal; Good (with restrictions); Bad (with many restrictions) and inadequate. The research from questionnaires showed that it is confirmed the hypothesis that the vacationers, residents, community of Ceclimar are favorable to the use of composting centers. The results have created a space beyond recycling, including the involvement of the local community in actions based on environmental quality, Permaculture, Solidarity Economy, income generation and multiplication for domestic residences. Based on the technical standards on the Solid Waste Policy for the responsibility of consumption that will enable sites favorable to public composting.

Integrated water resources management has been used for decades in various formats. The limited resources and the ever growing population keep imposing pressure on decision makers to better-, and reliably, manage the available waters. On the other hand, the continuous development in computing and modeling power has helped modelers and decision makers considerably. To use these models, assumptions have to be made to fill in the gaps of missing data and to approximate the current conditions. The type and amount of information available can also be used to help select the best model from the currently available models. Advances in data collection have not kept up to the pace of advances in model development and the need for more and reliable input parameter values. Hence, uncertainty in model input parameters also needs to be quantified and addressed. This research effort develops a spatially-based modeling framework to model watersheds from both water quantity and quality standpoints. In this research, Gridded Surface Sub-Surface Hydrologic Analysis (GSSHA) and CE-QUAL-W2 models are linked within the Watershed Modeling System (WMS); a GIS interface for hydrologic and hydraulic models, to better handle both models pre and post processing. In addition, stochastic analysis routines are developed and used to examine and address the uncertainty inherent in the modeling process of the interface between land and water in the designated watershed. The linkage routines are developed in WMS using C++. The two models are linked spatially and temporally with the general direction of data flow from GSSHA to CE-QUAL-W2. Pre-processing of the CE-QUAL-W2 model is performed first. Then stochastic parameters and their associated distributions are defined for stochastic analysis in GSSHA before a batch run is performed. GSSHA output is then aggregated by CE-QUAL-W2 segments to generate multiple CE-QUAL-W2 runs. WMS then reads the stochastic CE-QUAL-W2 runs upon successful completion for data analysis. Modelers need to generate a WMS Gage for each location where they want to examine the stochastic output. A Gage is defined by a segment and a layer in the CE-QUAl-W2 model. Once defined, modelers are able to view a computed credible interval with lower, upper bounds in addition to the mean time series of a pre-selected constituent. Decision makers can utilize this output to better manage watersheds by understanding and incorporating the spatio-temporal uncertainty for the land-water interface.

Due to the potential risk that cyanobacteria can cause to public health, the importance of the management of water bodies to control the toxic blooms, especially in reservoirs destined to the public supply, is evident. Thus, there is a clear need to develop techniques that can help existing monitoring, with the possibility of extending the area of ​​coverage in monitoring programs. Thus, the present study aimed to combine several methods of data acquisition, mainly obtaining continuously, such as the use of sensors for in situ evaluation of phytoplankton, especially cyanobacteria, through the detection of chlorophyll-a and phycocyanin, as well as the use of remote sensing for phytoplankton monitoring and with this information to build water quality prediction scenarios through mathematical modeling. The procedure aimed to improve data acquisition, especially the spatialization of data. For this purpose, the dynamics and water quality of the João Leite reservoir was characterised over 30 months using physical, chemical and biological parameters and trophic status index, to know the seasonality of the quality of the of the water body and present the main parameters and factors of water quality change. A continuous and spatial phytoplankton monitoring method was proposed for mapping concentrations of chlorophyll- a and cyanobacteria from Sentinel-2 satellite images with in situ and inferential observations to evaluate the performance of these to provide information on cyanobacterial blooms. The CE-QUAL-W2 model was calibrated from field data to evaluate the water quality dynamics and hydrodynamics of the reservoir. As a result, João Leite reservoir presented characteristic and similar patterns of the variation of the parameters in hydrological periods, and the results showed that the use and the occupation of the soil reflect in the characteristics of the quality of the water. In the majority of the evaluated points and times, good oxygenation of the waters and low concentrations of nutrients were demonstrated, being proved by the trophic state indexes. Both chlorophyll-a and cyanobacteria showed correlation between data measured in situ and estimated. The results can considered satisfactory since with the data of reflectance it was possible to validate the atmospheric correction, and the maps of estimate of chlorophyll- a and cyanobacteria presented the places and the months more prone to the greater proliferation of cyanobacteria. Thus, these results demonstrate the importance of the use of remote sensing for the monitoring of water quality, since with the use of this tool there is greater possibility of point coverage, being able to have a synoptic visualisation of the studied environment, identifying the most subject areas to the proliferation of cyanobacteria. The results of the modeling indicate that the reservoir presents periodic stratification, and in the warmer months the stratification is more evident and that in the colder months a mixture of the water column is noticed, possibly due to in those months there are more incidental winds in the region. In general, the highest values ​​of algae and cyanobacteria occur in the warmer months, where there is a higher solar incidence and larger periods of thermal stratification occur. It was also presented that the amount of algae and cyanobacteria on the surface changes the amount of oxygen dissolved in the surface region while the demand for sediment oxygen may be associated with both the oxygen consumption in the sediments and can also be used as a way to simulate the consumption of oxygen by the submerged organic matter, which is visible in the shallower areas of the reservoir. The results of the CE-QUAL-W2 model provided a comprehensive understanding of the spatial and temporal dynamics of the parameters analyzed during the modeling periods. The application of this model with the integration of fluorometers and remote sensing for the evaluation of water quality, should be better suited to water resource managers, to help them better understand the dynamics of physicochemical and biological processes and to be used as a warning system in cases of cyanobacteria blooms and to propose the best mitigation strategies. / Reservatório de água lênticos, rasos, com grande área de superfície e longos tempos de retenção hidráulica apresentam condições propícias para o desenvolvimento de cianobactérias. Devido o potencial risco que cianobactérias podem causar a saúde pública, evidencia-se a importância do gerenciamento dos corpos hídricos a fim de controlar as florações tóxicas, principalmente em reservatórios destinados ao abastecimento público. Assim, há uma clara necessidade de desenvolver técnicas que possam auxiliar os monitoramentos existentes, com a possibilidade de estender a área de abrangência em programas de monitoramento. O objetivo geral dessa pesquisa é avaliar um método de monitoramento contínuo e espacial de fitoplâncton, especialmente quanto à presença de cianobactérias, por meio da ficocianina e clorofila “a”, de modo a se ter informações de qualidade da água, para efetuar a previsão de cenários da dinâmica de cianobactérias, empregando modelagem matemática. Para tanto, foi caracterizada a dinâmica e a qualidade das águas do reservatório João Leite, ao longo de 30 meses, por meio de análises dos parâmetros físicos, químicos e biológicos, e índice de estado trófico, a fim de conhecer a sazonalidade da qualidade da água do corpo hídrico e apresentar os principais parâmetros e fatores de alteração da qualidade das águas. Foi proposto um método de monitoramento contínuo e espacial de fitoplâncton, para confecção de mapas de concentrações de clorofila “a” e cianobactérias a partir de imagens do satélite Sentinel-2, com observações in situ e a partir de inferências, para avaliar o desempenho desses em fornecer informações sobre proliferações de cianobactérias. Por último, o modelo CE-QUAL-W2 foi calibrado a partir de dados obtidos em campo, para avaliar a dinâmica da qualidade da água e hidrodinâmica do reservatório. Como resultado, o reservatório João Leite apresentou padrões característicos e semelhantes da variação dos parâmetros em períodos hidrológicos e os resultados demonstraram que o uso e a ocupação do solo refletem nas características da qualidade da água. Na maior parte dos pontos e tempos avaliados, foram apresentadas boa oxigenação das águas e baixas concentrações de nutrientes, sendo comprovados pelos índices de estado trófico. Tanto a clorofila “a” quanto cianobactérias demonstraram correlações entre os dados medidos in situ e os estimados. Os resultados podem ser considerados satisfatórios, uma vez que com os dados de refletância foi possível validar a correção atmosférica e os mapas de estimativa de clorofila “a” e cianobactérias apresentaram os locais e os meses mais propensos à maior proliferação de cianobactérias. Assim, esses resultados demonstram a importância do uso do sensoriamento remoto para o monitoramento da qualidade das águas, uma vez que com o uso dessa ferramenta há maior possibilidade de abrangência de pontos, podendo ter uma visualização sinóptica do ambiente estudado, identificando as áreas mais sujeitas à proliferação de cianobactérias. Os resultados da modelagem indicam que o reservatório tem a tendência a se comportar com estratificação periódicas, sendo que nos meses mais quentes a estratificação é mais evidente e que nos meses mais frios uma mistura da coluna d’água é notada, possivelmente em função de que nesses meses há mais ventos incidentes na região. De um modo geral, os maiores valores de algas e cianobactérias ocorrem nos meses mais quentes, em que há maior incidência solar e ocorre maiores períodos de estratificação térmica. Foi ainda apresentado que a quantidade de algas e cianobactérias na superfície altera a quantidade de oxigênio dissolvido na região da superfície enquanto a demanda por oxigênio sedimentar, pode estar associado tanto ao consumo de oxigênio nos sedimentos quanto pode ser também usada como forma de simular o consumo de oxigênio pela matéria orgânica submersa, que é visível nas áreas mais rasas do reservatório. Dessa forma, foi apresentado que os resultados do modelo CE-QUAL-W2 forneceram uma compreensão abrangente da dinâmica espacial e temporal dos parâmetros analisados durante os períodos modelados. A aplicação deste modelo com a integração do uso de fluorômetros e sensoriamento remoto para a avaliação da qualidade da água, devem ser mais indicados aos gestores de recursos hídricos, para auxiliá-los a entender melhor a dinâmica dos processos físico- químicos e biológicos e principalmente para serem utilizados como um sistema de alertas em casos de florações de cianobactérias, para que possam propor as melhores estratégias de mitigação.

Water quality models in the Colorado River Basin have been developed for the basin, river, and individual reservoirs. They are used to support water quality programs within the basin. The models are periodically reviewed and updated to improve the accuracy of simulations. Improving the usefulness of the Lake Powell model, one of the key reservoirs in the basin, is the subject of this study. Lake Powell is simulated using a hydrodynamic and water quality model, CE-QUAL-W2. Previously the model has been used at Lake Powell to simulate hydrodynamics, temperature, and total dissolved solids with a reasonable degree of accuracy. An additional parameter, dissolved oxygen, will be added to the simulations and then calibrated with observed data to verify accuracy. Dissolved oxygen distributions in Lake Powell vary seasonally and change under different hydrologic cycles. They are a function of physical, biological, and chemical processes. Few measurements of these processes in Lake Powell exist. To compensate for the lack of data an empirical method of loading oxygen demand to the model is developed and tested. Observed limnological processes in the reservoir guide the development of the empirical methods. The methods are then tested in 16 year model simulations and compared with dissolved oxygen measurements from the 16 year period. By accurately reproducing the dissolved oxygen distributions the Lake Powell model will have improved accuracy and also broaden its usefulness.

Episodic processing, among all memory systems, shows to be the most affected along aging. The episodic memory is a subsystem of memory responsible for receiving and storing information about certain episodes or events, temporally dated, high lighting a spatiotemporal relationship between them. One way of assessing this construct would be using behavioral criteria for identifying information about what happening, where and when, which are the basic components of “What-Where-When” paradigm, or else, by proposing to replace the temporal component by context, “What-Where-Which” paradigm. Thus, the objective of this research was to analyze the effect of aging on episodic memory, assessed by two experimental paradigms, to study the correlation of these tests with classic measures of episodic memory. We used a sample with 70 volunteers, divided in two group: younger (N = 35, M = 22,74; SD= 2,99) and older (N = 35, M = 62,54; SD = 4,82) adults. The evaluation protocol was composed of: (i) test based on the paradigm "What-Where-When"; (ii) test based on the paradigm "What-Where-Which"; (iii) classic episodic memory tests; and (iv) a neuropsychological battery, the latter being applied only to the elderly group. The results showed that different episodic memory task apparently measuring something in common. Comparisons between group showed effective impairment associated with aging for all aspects evaluated by the test "What-Where-When", and the integration aspect was the component that suffered the greatest decline associated with age [F(1, 68)= 53,86; p < .001; η² = .442]. Other results showed that Free Recall also presented decline [F(1, 68)= 18,60; p < .001; η² = .215]. However, it was not found significant differences between groups for the task based on the paradigm "What-Where-Which". The findings of this study show that task-based paradigm "What-Where-When" and "What-Where-Which" are promising instruments for measurement of episodic memory. However, apparently the temporal aspect was more sensitive to detect possible changes related to age. / O envelhecimento humano provoca declínios em diversas funções cognitivas. O processamento episódico, dentro todos os sistemas de memória, demonstra ser um dos mais afetados durante a velhice. A memória episódica é um subsistema mnemônico responsável por receber e armazenar informações sobre determinados episódios ou eventos temporalmente datados, existindo uma relação espaço-temporal entre eles. Uma forma de avaliação desse construto seria através de critérios comportamentais para identificação de informações sobre o que aconteceu, onde e quando, sendo esses os componentes básicos do paradigma “Que-Onde-Quando”, ou então, por meio de outra proposta que substitui o componente temporal pelo contextual “Que-Onde-Qual contexto”. Diante disso, o presente trabalho objetivou analisar o efeito da idade sobre a memória de integração, mensurada por dois paradigmas experimentais, e estudar os correlatos destas tarefas com medidas clássicas de memória episódica. Para tal utilizou-se uma amostra de 70 voluntários, dividida em dois grupos: Adultos jovens - GA (N = 35, M = 22,74; DP= 2,99) e Idosos – GI (N = 35, M = 62,54; DP = 4,82). O protocolo de avaliação utilizado foi composto por: (i) Teste baseado no paradigma “Que-Onde-Quando”; (ii) Teste baseado no paradigma “Que-Onde-Qual contexto”; (iii) Testes clássicos de memória episódica; e (iv) uma bateria neuropsicológica, sendo essa última aplicada apenas ao grupo de idosos. Os resultados mostraram que as diferentes medidas de memória episódica utilizadas aparentemente estão medindo algo em comum. As comparações efetivamente mostraram haver comprometimento, associado ao envelhecimento, de todos os aspectos avaliados pelo teste baseado no paradigma “Que-Onde-Quando”, sendo a “integração” o componente que sofreu maior declínio proporcional associado ao aumento da idade [F(1, 68)= 53,86; p < .001; η² = .442]. Achados similares a esse também foram verificados para tarefa de Recordação Livre Imediata (testes clássico de memória episódica) [F(1, 68)= 18,60; p < .001; η² = .215]. Entretanto, não foi registrada diferença significativa entre os grupos para a tarefa baseada no paradigma “Que-Onde-Qual contexto”. Os achados do presente estudo evidenciaram que tarefas baseadas no paradigma “Que-Onde-Quando” e “Que-Onde-Qual contexto” são promissores instrumentos válidos de mensuração da memória episódica. Porém, aparentemente a proposta relacionada ao aspecto temporal mostrou-se mais sensível para detecção de possíveis alterações relacionadas à idade.
