Substance abuse is the overindulgence in and dependence on a drug or chemical leading to detrimental effects on the individual’s health and the welfare of those surrounding him or her. Logistic regression analysis is an important tool used in the analysis of the relationship between various explanatory variables and nominal response variables. The objective of this study is to use this statistical method to determine the factors which are considered to be significant contributors to the use or abuse of substances in school-aged children and also determine what measures can be implemented to minimize their effect. The logistic regression model was used to build models for the three main types of substances used in this study; Tobacco, Alcohol and Drugs and this facilitated the identification of the significant factors which seem to influence their use in children.

In this work, we introduce several novel approaches to feedback controller design, known collectively as the “Robust Bode” methods, which adapt classical control principles to a modern robust control (H∞) framework. These methods, based on specially modified Bode diagrams extend familiar frequency-domain controller design techniques to linear and nonlinear, single–input/single– output (SISO) and multi–input/multi–output (MIMO) systems with parametric and/or unstructured uncertainties. In particular, we introduce the Contoured Robust Controller Bode (CRCBode) plots which show contours (level-sets) of a robust metric on the Bode magnitude and phase plots of the controller. An iterative loop shaping design procedure is then employed in an attempt to eliminate all intersections of the controller frequency response with certain forbidden regions indicating that a robust stability and performance criteria is satisfied. For SISO systems a robust stability and performance criterion is derived using Nyquist arguments leading to the robust metric used in the construction of the CRCBode plots. For open-loop unstable systems and for non-minimum phase systems the Youla parametrization of all internally stabilizing controllers is used to develop an alternative Robust Bode method (QBode). The Youla parametrization requires the introduction of state-space methods for coprime factorization, and these methods lead naturally to an elegant connection between linear-quadratic Gaussian (LQG) optimal control theory and Robust Bode loop-shaping controller design. Finally, the Robust Bode approach is extended to MIMO systems. Utilizing a matrix norm based robustness metric on the MIMO CRCBode plots allows cross-coupling between all input/output channels to be immediately assessed and accounted for during the design process, making sequential MIMO loop-shaping controller design feasible.

The subject matter of mental illness has fascinated artists and writers for centuries. Filmmakers have responded in diverse and innovative ways to the artistic challenge of portraying mental illness. In this thesis, I focus on the representations of mental illness in six recent films from Australia and New Zealand: Sweetie (Jane Campion, 1989), An Angel at My Table (Campion, 1990), Bad Boy Bubby (Rolf de Heer, 1993), Heavenly Creatures (Peter Jackson, 1994), Angel Baby (Michael Rymer, 1995) and Shine (Scott Hicks, 1996). In each film, the protagonist is diagnosed, or treated by others, as mentally ill. Mental illness is portrayed as an affliction which the protagonist struggles to overcome. I argue that these films cultivate a relationship of empathy between the mentally ill character and the spectator. Whereas the related emotion of sympathy involves feeling sorry for someone, empathy involves feeling with that person; in other words, rather than feel for these mentally ill characters, we are invited to feel like they do.

Também, no contexto mundial, poucos são os estudos que propõem metodologias alternativas para a determinação do fator C em climas tropicais. Assim, o objetivo desta pesquisa foi o de elaborar um procedimento metodológico para a determinação do fator C a partir da quantificação das perdas de solos e índices de vegetação em pastagens e cana-de-açúcar. Foram utilizados dados multissensores correlacionados aos valores do fator C estimados em 11 parcelas de monitoramento de erosão. As parcelas foram instaladas na bacia hidrográfica do córrego Monjolo Grande (Ipeúna/SP) e na bacia hidrográfica do ribeirão Jacutinga (Rio Claro/SP). Estas bacias apresentam semelhanças quanto às dimensões em área e uso da terra e variabilidade quanto às características pedológicas e de relevo. Em todas as parcelas com pastagens, as perdas de solo foram inferiores a 1,5 t ha-1 ano-1 e o fator C foi de 0,1. Mesmo em condições diversas de paisagem, as gramíneas presentes nas áreas de pastagens se comportaram de maneira similar frente aos processos erosivos. Por outro lado, verificou-se diferenças nas perdas de solos nas parcelas com cana-de-açúcar localizadas em ambas as áreas de estudo. Nos solos argilosos da bacia hidrográfica do ribeirão Jacutinga as perdas variaram de 0,8 a 2,76 t ha-1 ano-1. Já nos solos arenosos da bacia hidrográfica do córrego Monjolo Grande as perdas variaram de 49 a 84,8 t ha-1 ano-1. Assim, as diferenças nas perdas de solo em canaviais são derivadas das condições físicas de cada paisagem. Os valores do fator C nos canaviais variaram de 0,13 a 0,23 para a bacia hidrográfica do ribeirão Jacutinga e de 0,41 a 0,43 para a bacia hidrográfica do córrego Monjolo Grande. Assim, no contexto regional estudado, a expansão e o cultivo de cana-de-açúcar é realizado indistintamente, não considerando as condições de fragilidade natural de cada ambiente. Os dados de perdas de solo obtidos em campo correlacionados aos dados de sensoriamento remoto proporcionaram a criação de uma metodologia de determinação do Fator C. A utilização desta metodologia possibilitou a melhoria da modelagem da MEUPS em eventos individuais de chuva em ambas as áreas de estudo. / In Brazil, there are few studies on the estimation of soil losses in sugarcane and acquisition the factor C in the USLE in landscapes with different potential natural erosion. Also, in the global context, there are few studies that propose alternative methods for the extraction of Factor C in tropical climates. The objective of this research was to develop a preliminary methodological procedure to extract the factor C for pasture and sugarcane. Multisensor data correlated to the Factor C values estimated at plots were used. The plots were installed in the watershed of the stream Monjolo Grande (Ipeúna / SP) and Jacutinga (Rio Claro / SP). These basins have similarities as to the area and land use and variability as to the soil and relief. In all plots with pasture, soil losses were less than 1.5 t ha-1 yr -1 and C factor was 0.1. Even under various conditions of landscape, grasses present in pasture areas behaved in a similar way to the front erosion. On the other hand, there are differences in the losses of soil in the plots with sugarcane located in both study areas. In clay soils of the watershed of Jacutinga creek losses ranged from 0.8 to 2.76 t ha-1 yr-1 . In the sandy soils of the watershed stream Monjolo Grande losses ranged from 49 to 84.8 t ha-1 yr-1 . Thus, differences in soil loss in sugarcane fields are derived from the physical conditions of each landscape. The values of the C factor in the cane fields ranging from 0.13 to 0.23 for the watershed of the Jacutinga creek and 0.41 to 0.43 for the watershed stream Monjolo Grande. Thus, in the regional context studied, the expansion and sugarcane cultivation is done indiscriminately, without considering the fragility natural conditions of each environment. The data obtained in soil losses related to the field of remote sensing data led to the creation of a methodology for determining factor C. The use of this methodology improve the modeling of MEUPS in individual rainfall events in both study areas. / FAPESP: 2012/08527-5 / FAPESP: 2012/19935-7

A aplicação de práticas inadequadas às múltiplas funcionalidades do solo tem provocado a erosão hídrica acelerada como um dos principais processos de degradação deste recurso. No esforço de colaborar em estudos de conservação dos solos, avaliaram-se os modelos preditivos de erosão hídrica MEUPS – Equação Universal de Perda de Solo Modificada (Williams, 1975) e WEPP – Water Erosion Prediction Project (Laflen, 1991) por meio da comparação das estimativas de perda de solo com dados empíricos de parcelas experimentais de pinos de erosão. A variabilidade de parâmetros envolvidos nas simulações motivou a definição de duas bacias hidrográficas de características hidrossedimentológicas distintas, as bacias do ribeirão Jacutinga (Rio Claro – SP) e do córrego do Monjolo Grande (Ipeúna - SP), para avaliar o comportamento erosivo em solos oriundos de argilitos e arenitos, respectivamente. No período experimental de junho/2013 a agosto/2014, parcelas experimentais de 1 m2 foram monitoradas em diferentes condições de declividade, posição topográfica, forma da vertente e cobertura vegetal – pastagem, cana-de-açúcar, e vegetação ripária, e em solo descoberto. Nos Argissolos e Cambissolos de textura argilosa foram registradas perdas de 0,018 a 0,066 ton/ha.ano-1, e deposição entre 0 e 0,026 ton/ha.ano-1, e nos Neossolos Quartzarênicos e Argissolos de textura arenosa, houve predomínio deposicional, entre 0,004 e 0,085 ton/ha.ano-1, e perdas de 0,002 a 0,11 ton/ha.ano-1. As maiores perdas estão associadas a maiores porções das frações de areia fina e silte, e fraca agregação pelos baixos teores de argila e matéria orgânica. O maior percentual de cobertura vegetal foi determinante para as menores perdas, evidenciando maior fator de proteção do solo por plantio direto que por plantio convencional. As simulações foram realizadas para o ano experimental e para eventos específicos de chuva: Evento 1 - intensidade superior a 50 mm/h, e Evento 2 – intensidade inferior a 14 mm/h. A avaliação dos modelos foi dada pelos coeficientes de determinação (R2), de Pearson (PR2) e de Nash-Sutcliffe (COE), sendo o último o mais eficiente. A MEUPS foi simulada com obtenção do comprimento de rampa (L) pelo método automático (Desmet e Govers, 1996) e manual (distância linear). As estimativas foram satisfatórias a muito boas (COE médio > 0,7) principalmente nos solos argilosos com predomínio das perdas, e com fator L manual. No WEPP, foram realizadas simulações pelo módulo vertente (software WEPP) e bacia (GeoWEPP – versão do WEPP em SIG). Em todas as simulações do WEPP vertente foram obtidos resultados insatisfatórios (COE < 0). No GeoWEPP, as estimativas dadas em classes de perda e deposição apresentaram classes coincidentes aos registros das parcelas, entre 20% e 90% em solos argilosos e entre 40% e 50% nos solos arenosos. As melhores estimativas ocorreram para chuvas de baixa intensidade, evidenciando a inadequação do modelo em eventos extremos e em condições tropicais. Ressalta-se que o período experimental representa um ano atípico de chuva, com baixos índices pluviométricos em comparação às médias anuais históricas. Considerando os valores superestimados do WEPP e GeoWEPP, apenas a MEUPS mostrou-se adequada como ferramenta para estudos de erosão hídrica, evidenciando a contribuição deste modelo na gestão do uso da terra e no planejamento de sistemas agrícolas e práticas conservacionistas. / The land use intensification becomes more and more evident due the growing of food production and supply to the human population. The application of inadequate practices to the multiple functions has shown the accelerated water erosion as a major degradation processes for this resource. In an effort to colaborate for soil conservation studies, this research aimed to evaluate the predictive models of erosion MUSLE – Modified Universal Soil Loss Equation (Williams, 1975) and WEPP – Water Erosion Prediction Project (Laflen, 1991) by comparing the estimated soil loss and empirical data from pins experimental plots. The variability of simulated parameters led the definition of two watersheds with different hydrossedimentological characteristics, watershed of stream Jacutinga (Rio Claro – SP/Brazil) and stream Monjolo Grande (Ipeúna – SP/Brazil) to assess the erosive behavior in soils derived from mudstones and sandstones, respectively. In the experimental period of June/2013 to August/2014, experimental plots of 1 m2 were monitored in different conditions of slope, topographic position, slope shape and vegetation cover - grazing, sugarcane, riparian vegetation and bare soil. In Lixisols and Cambisols clayey the losses registered were 0.018 to 0.066 ton/ha.year-1 and deposition between 0 and 0.026 ton/ha.year-1 , and in Quartzarenic Neosols and Lixisols of sandy texture, where dominated depositional process, between 0.004 and 0.085 ton/ha.year-1 , and the losses were 0.002 to 0.11 ton/ha.year-1 . The greatest losses are associated with the largest portion of fine sand and silt fractions, and weak aggregation by low levels of clay and organic matter. The highest percentage of vegetation cover was crucial for smaller losses, showing greater soil protection factor for direct plantation which in conventional tillage. The simulations were performed for the experimental year and specific rainfall events: Event 1 - intensity greater than 50 mm/h, and Event 2 - intensity less than 14 mm/h. The evaluation of the models was given by the coefficients of determination (R2 ), Pearson (PR2 ) and NashSutcliffe (COE), the latest being the most eficiente one. The MUSLE was simulated obtaining the ramp length (L) by the automatic method (Desmet and Govers, 1996) and manual (linear distance). Estimates were satisfactory to very good (average COE> 0.7) especially in clay soils with predominance of soil losses, and manual factor L. For WEPP, the simulations were performed by hill module (WEPP software) and watershed (GeoWEPP – GIS version for WEPP). In all aspects, WEPP simulations have obtained unsatisfactory results (COE < 0). In GeoWEPP, the estimatives given in loss and deposition classes showed coincidence of classes and records of the plots between 20% and 90% in clayey soils, and between 40% and 50% in sandy soils. The best estimates occurred for low intensity rains, pointing out the inadequacy of this model in extreme events and in tropical conditions. It is emphasized that the rain in the experimental period atypical, with low rainfall compared to historical annual averages. Considering the overestimated values of WEPP and GeoWEPP, only MUSLE was adequate as a tool to water erosion studies, especially for the contribution of this model in land use management, in the planning of agricultural systems and conservation practices. / FAPESP: 2012/08710-4
