Abstract:
The inhabitants of marine benthos must combat the ecological pressure caused by predation, competition and fouling through a series of mechanisms, one of which is chemical defense. This type of protection is particularly extended among sessile and/or sluggish organisms, such as sponges, soft corals or ascidians. The strategies to prevent predation are related to bad taste rather than to toxicity. Moreover, they must be considered along with nutritional quality, since the more nutritious the prey, higher quantities or more potent repellents are needed to gain protection. The production of defensive secondary metabolites is energetically expensive. For this reason, the Optimal Defense Theory (ODT) predicts that defenses must be allocated in the most valuable or more exposed structures or body-regions. In Antarctic communities, the main predators are asteroids, and defensive agents are hence expected to accumulate in superficial layers of potential prey. But dense populations of amphipods, which associate opportunistically with biosubtrata, obtaining both refuge and direct or indirect sources of nutrition, are also very influencing on these bottoms. It has been reported that chemical defenses are very common in Antarctic organisms, in accordance with our results. However, the research effort has not been the same for all the groups, and there are still many aspects to learn on the chemical ecology, like the identification of the implicated products, their mode of functioning or their localization and origin. This PhD has focused on three relevant groups of the Antarctic benthos, quite understudied: hexactinellid sponges, soft corals and colonial ascidians. Two influencing sympatric predators were selected, the sea star Odontaster validus, which is a known model predator, and for the first time, the amphipod Cheirimedon femoratus, used to perform feeding experiments for the detection of repellent chemical defenses. We designed a new protocol which provided numerous methodological profits, as well as a remarkable discriminatory potential for unpalatable activities. In a survey with 31 species of Antarctic organisms, a larger incidence of unpalatable activities was recorded towards C. femoratus than against the asteroid, especially in algae and sponges, in which amphipods may particularly influence defenses distribution for representing potential host-preys. Some organisms instead, seemed to exploit alternative defensive strategies. The ecological success of the three studied groups is probably related to the presence of chemical defenses. In hexactinellid sponges these are weak, yet compensated with a low energetic content, and derive from primary metabolites, such as steroid derivates. Some glucosphingolipids instead, could have a chemotaxonomical value as chemical markers in rossellid sponges. In soft corals, chemical protection is obtained from products originating from both, primary (wax esters) and secondary metabolism (sesquiterpenoids), which seem to cooperate in an additive way, and are likely exuded within the coral mucus in living specimens. The use of primary metabolites for defense represents an effective energy saving strategy. In colonial ascidians, defensive secondary metabolites of terpenoid and alkaloid nature with potent bioactivities predominate, and in some species these are accumulated in internal tissues. Presumably, this distribution is related to the production of chemically defended lavae. Some bioactive secondary metabolites isolated from various sources, like the meridianins, may suggest a broad evolutionary retention, or a symbiotic origin. Regarding bacterial antifouling, ascidians exhibited poor activity, while some soft corals did display inhibition. With this work we provide the identification, localization, and possible origin of several defensive agents in three relevant groups of Antarctic benthic invertebrates.
Los habitantes del bentos antártico combaten la depredación, la competencia y el recubrimiento desarrollando mecanismos como la defensa química. Ésta estrategia está particularmente extendida entre organismos sésiles y organismos de cuerpo blando. Las defensas repelentes contra depredadores han de considerarse junto con la calidad nutricional, pues las dietas muy energéticas enmascaran la repelencia. La producción de metabolitos secundarios defensivos es costosa. Por ello, la Teoría de Defensa Optimizada (ODT) prevé que han de localizarse en las regiones corporales más valiosas o expuestas. En las comunidades antárticas los principales depredadores son las estrellas de mar y se postula la concentración de defensas en áreas superficiales en las presas. Pero también influyen las poblaciones de anfípodos asociados a los biosustratos, obteniendo en ellos refugio y fuente de alimentación. Esta tesis se centra en las defensas químicas de tres grupos relevantes del bentos antártico relativamente poco estudiados: esponjas hexactinélidas, corales blandos y ascidias coloniales. Se seleccionaron dos depredadores simpátricos, la estrella Odontaster validus y, por primera vez, fue utilizado el anfípodo Cheirimedon femoratus. Diseñamos un nuevo protocolo con numerosas ventajas metodológicas además de un gran potencial discriminatorio, y observamos que en 31 especies hubo mayor repelencia hacia el anfípodo que hacia la estrella, sobretodo en algas y esponjas, que podrían representar potenciales huéspedes-presa. A partir de aquí estudiamos muestras de los tres grupos seleccionados. En hexactinélidas, las defensas químicas son más débiles y derivadas del metabolismo primario, pero compensadas con un bajo valor nutricional. Algunos glucoesfingolípidos, podrían tener valor quimiotaxonómico como marcadores de la familia Rossellidae. En corales blandos existen metabolitos de defensa primarios y secundarios operando sinérgicamente, y probablemente forman parte del mucus superficial. En ascidias coloniales, los metabolitos defensivos son secundarios y muy potentes; además, en algunas especies éstos tienden a acumularse en tejidos internos, presumiblemente para producir larvas protegidas químicamente. Las ascidias mostraron poca actividad antibacteriana, pero algunos corales exhibieron respuestas inhibitorias. Esta Tesis proporciona la estructura, distribución y posible origen de los metabolitos responsables de las actividades defensivas en tres grupos relevantes de invertebrados antárticos.

Abstract:
Introducción: La desnutrición crónica (DC) es uno de los problemas más serios en el mundo. En el Perú 1 de cada 6 niños menores de 5 años tienen desnutrición crónica y en las regiones de sierra y selva la proporción aumenta. Objetivos: Comparar los factores asociados a la desnutrición crónica en niños peruanos de 6 a 23 meses de las 3 regiones naturales en un análisis secundario del Monitoreo Nacional de Indicadores Nutricionales 2010. Materiales y métodos: Análisis secundario de la base de datos de la encuesta Monitoreo Nacional de Indicadores Nutricionales (MONIN) 2010. Se calcularon las prevalencias de desnutrición crónica a nivel nacional, regiones naturales y para cada uno de los indicadores. Se realizó un análisis multivariado de regresión logística para cada región para identificar la fuerza de asociación. Resultados: Se encontraron 8 factores comunes a las tres regiones naturales. Entre ellos, el ser hijo de madres sin educación o solo primaria (costa OR: 2.04, sierra OR: 3.75 y selva OR: 3.05), no tener diversidad alimentaria (costa OR: 2.95; sierra OR: 3.14 y selva OR: 2.21) e inadecuadas prácticas de alimentación infantil (costa OR: 2.41; sierra OR: 1.73 y selva OR: 1.93). En la costa además estuvo el factor tipo de piso (OR: 1.85). En la sierra otros factores fueron ser hijo de madre con <6 controles prenatales (OR: 2.09), niños con <6 controles prenatales (OR: 2.09) y no disponer de recursos sanitarios (OR: 1.84). En la selva otros factores fueron no tener todas las vacunas básicas para la edad (OR: 2.26) y no disponer de recursos sanitarios (OR: 2.33). Conclusiones: Al comparar los factores se encontró algunas diferencias entre las regiones; la selva tuvo más factores asociados a la desnutrición crónica que la costa y la sierra. Palabras clave: Desnutrición crónica, regiones naturales, factores.
--- Background: Chronic malnutrition (CM) is one of the most serious problems in the world. In Peru 1 in 6 children under 5 years of age suffer from chronic malnutrition and the proportion increases in the regions highlands and jungle. Objective: To compare the factors associated with chronic malnutrition in Peruvian children from 6 to 23 months of age of the 3 natural regions in a secondary analysis of the National Monitoring of Nutritional Indicators 2010. Materials and methods: Secondary analysis of the database of the National Monitoring of Nutritional Indicators (MONIN) 2010. The prevalence of chronic malnutrition nationwide, natural regions and for each of the indicators was calculated. A multivariate logistic regression analysis for each region to identify the strength of association was performed. Results: There were 8 factors common to the three natural regions: Among them, being the child of mothers without education or only elementary school (coast OR: 2.04, highlands OR: 3.75 and jungle OR: 3.05), not having dietary diversity (coast OR: 2.95; highlands OR: 3.14 and jungle OR: 2.21) and being a child with inadequate feeding practices (coast OR: 2.41; highlands OR: 1.73 and jungle OR: 1.93). Besides on the coast one factor was type of floor (OR: 1.85). In the highlands, another factors were being son of mother with less 6 prenatal controls (OR: 2.09) and not having sanitation resources (OR: 1.84). In the jungle the other factors were not having all the basic vaccines for age (OR: 2.26) and not having sanitation resources (OR: 2.33). Conclusions: Comparing the factors was found some differences among the regions; the jungle had more factors associated with chronic malnutrition than the coast and the highlands regions. Keywords: Chronic malnutrition, natural regions, factors.

Algunos trabajos de investigación afirman reconocer un principio subyacente en el Sistema del Tratado Antártico que compartiría características del patrimonio común de la Humanidad. De igual manera, es posible encontrar propuestas para la instauración de un estatuto jurídico basado en esta concepción. Sin embargo, un análisis conceptual e histórico permitirá concluir que no es posible identificarlo en la regulación actual que rige sobre el continente antártico y que su eventual consagración incluso podría resultar contraproducente

Abstract:
En el Perú se han identificados ciertos síntomas señalados por la literatura en economía política bajo la teoría de la “maldición de los recursos naturales, siendo caracterizado por ser un Estado dependiente de las rentas de recursos naturales, presentar un sistema político-institucional débil, donde persiste la desigualdad económica y social y una pobre diversificación productiva. En este marco, un balance general del impacto de los recursos a nivel subnacional muestra fuertes contraste donde, por un lado, encontramos regiones con una persistencia de la desigualdad y la conflictividad social, numerosos casos de corrupción y reducida eficiencia en el gasto público, mientras que otras regiones tienen resultados positivos en la gestión de rentas extractivas ¿Por qué bajo algunos contextos las rentas extractivas no han conducido a resultados negativos a nivel subnacional y en qué condiciones sí ha sido provechoso? La presente investigación centra su atención en el gobierno regional de Moquegua (2002-2018), región con altos ingresos por minería pero que, a diferencia de otras regiones mineras, ha mostrado un desempeño positivo en términos sociales, económicos y políticos, siendo la segunda región con mayor desarrollo humano y prestación de servicios públicos, además de ser considerada como una de las regiones más competitivas en el Perú Considerando la importancia del contexto al momento de la llegada de los recursos, el argumento central propone que los antecedentes institucionales y una activa participación de la sociedad civil son factores claves no solo para constreñir una trayectoria negativa, sino para trazar un aprovechamiento positivo de los recursos. Además, la intensidad de los factores identificados es fundamental para entender la variación al interior de la región. Finalmente, estos factores nos ayudarán a comprender la trayectoria de otras regiones considerando el contexto

Abstract:
Based upon the export product space, this paper shows the main features of the export product composition of Peru and its regions. With respect to export baskets, these include: a high con- centration in few commodities; a relatively low degree of similarity between products; relatively high levels of productivity at the international level, and; enormous undiscovered or untapped export potential. In addition, this paper analyzes the hypothesis that the natural resource curse affects regional growth, employment and export diversification. Subject to the limitations of the data and the heterogeneous panel methods employed, estimation results indicate that the share of natural capital out of the total tangible wealth and natural capital per capita seems, on average and in a relatively statistically robust way, to spur growth, primary employment and export concentration in a few products. Consequently, the natural resource curse for the Peruvian regions is not about growth but about low regional development, since such resources do not have a significant impact on secondary and tertiary employment or on export product diversification.
Basado en la red de espacio de productos de exportación, este trabajo muestra las principales características de la composición de productos de exportación del Perú y sus regiones. Entre ellas: la de ser altamente concentrada en pocos productos intensivos en el uso de recursos naturales (RN), muy distantes unos de otros, de altos niveles de productividad internacional relativos al valor agregado real per cápita de cada región y de la economía en general, y de un enorme potencial de exportación todavía no explotado o descubierto. De otro lado, se analiza la validez de la hipótesis de la maldición de los efectos de los RN sobre el crecimiento y complementariamente sobre el empleo y la diversificación de los productos de exportación a nivel regional. Sujeto a las limitacio- nes de la información y métodos de paneles heterogéneos empleados, la evidencia relativamente robusta estadísticamente indica que la participación del capital natural del total de riqueza tangible y el capital natural per cápita han incidido en promedio positivamente en el crecimiento regional, el empleo relativo del sector primario, y la concentración de los principales productos de exportación. En consecuencia, la ‘maldición’ radica en la dependencia de las regiones en los RN para crecer retardando así el desarrollo regional por los efectos no significativos sobre elempleo secundario y terciario, y el proceso de diversificación de exportaciones.

Abstract:
El objetivo de esta tesis es caracterizar el viento en la Península Ibérica mediante observaciones y modelos climáticos regionales, analizar los errores en las simulaciones y proponer e implementar mejoras físicas para la reproducción del viento en superficie. La metodología consiste en varios pasos. Primero, se han realizado un control de calidad y unificación de registros para crear una base de datos observacionales con una densidad sin precedentes (514 estaciones) de series temporales horarias de velocidad y dirección del viento durante 2002-2007. Segundo, los modelos climáticos regionales han sido usados en el estudio de la climatología del viento para superar las limitaciones que plantean las observaciones. Se ha realizado una simulación climática cubriendo la Península Ibérica a 10 km de resolución espacial durante 1959-2007 con el modelo MM5. Tercero, para facilitar la caracterización del viento y realizar una validación de las simulaciones a escala regional se han usado técnicas multivariantes (métodos de clustering y análisis de componentes principales). Con estas técnicas, el área de estudio se ha dividido en varias regiones atendiendo a los distintos modos de variabilidad del módulo del viento. Cuarto, para analizar el sesgo en el módulo del viento se ha realizado dos simulaciones análogas a la del modelo MM5 para el periodo de observaciones (2002-2007) con el modelo WRF. Una de las simulaciones incluye una parametrización de los efectos topográficos. Por último, se ha modificado el término de fricción topográfica del modelo WRF para considerar la influencia de la estabilidad atmosférica. Para ello se usa la energía cinética turbulenta que es incluida en el esquema de capa límte usando una ecuación de diagnótico. Los resultados de la caracterización del viento mediante las observaciones muestra una gran diversidad regional del viento en la Península Ibércia, puesta de manifiesto en el ciclo annual, la rosa de los vientos, los histogramas de la velocidad del viento así como en las correlaciones temporales entre las series medias regionales. La escala sinóptica juega un papel esencial en el análisis de la dirección promedio del viento y las anomalías del módulo. La simulación con MM5 es capaz de reproducir las principales características del viento en la Península Ibérica y proporciona un valor añadido respecto de las condiciones de contorno. La simulación ha sido usada en diversos estudios. Primero, ha permitido analizar las tendencias del módulo del viento mostrando una disminución en invierno asociada a la disminución de situaciones ciclónicas, mientras que existe un aumento en verano debido al incremento de circulaciones térmicas favorecidas por el aumento de las temperaturas. Segundo, la simulación ha servido para estimar el recurso eólico en España usando una herramienta web que facilita el acceso a la información del viento para cualquier usuario. Tercero, con la simulación se han analizado las limitaciones de las observaciones mostrando que el periodo de datos disponibles puede ser insuficiente para describir la climatología del viento en el oeste peninsular y señalando la necesidad de incluir más estaciones en regiones montañosas como el Sistema Ibérico para una mejor caracterización del viento. El mayor inconveniente que presenta tanto la simulación realizada con MM5 como la análoga con WRF es la sobrestimación del módulo del viento. La inclusión de la parametrización de la topografía a subescala en WRF muestra que el sesgo de la velocidad del viento puede ser mejorado incluyendo dichos effectos topográficos. Sin embargo, esta parametrización puede infraestimar el viento observado en situaciones muy ventosas. El ciclo diario del módulo del viento muestra que dicha infraestimación viene dada por el comportamiento inadecuado durante el día. La relación de la velocidad convectiva, la energía cinética turbulenta y la altura de la capa límite con el sesgo del viento muestran una dependencia de la fricción topográfica con las condiciones de estabilidad. La modificación de la fricción topográfica con los parámetros de estabilidad mejora el ciclo diario del viento, aunque ésta depende del mes del año. Esta tesis contribuye a mejorar el entendimiento del viento observado y simulado en la Península Ibérica. Además, supone un avance en los modelos regionales puesto que mejora el viento simulado.
The aim of this Thesis is (1) to characterize the surface wind over the Iberian Peninsula through the use of observations and Regional Climate Models (RCMs), (2) to analyze the simulation errors and (3) to propose and implement improvements in the model physics for enhancing the wind reproduction. The methodology consists of various procedures. First, a quality-controlled database of surface wind (speed and direction) has been built. This database has no precedent and is composed of 514 hourly series covering the Iberian Peninsula for the period 2002-2007. Second, RCMs are used to assess the wind climatology and to overcome the limitations of the observations. A regional climate simulation covering the Iberian Peninsula with 10 km of spatial resolution during 1959-2007 is performed. Third, multivariate techniques (clustering analysis and principal components analysis) are applied to facilitate the wind characterization and validate the simulation at regional scale. The Iberian Peninsula is split in several regions attending to similar wind speed variability. Fourth, two additional simulations are run with WRF model during the observational period (2002-2007) in order to study the parameterization effect of the subgrid topographic friction. Finally, the term of the subgrid topographic fiction is modified in WRF in order to consider the influence of the atmospheric stability in the representation of surface wind. The results indicate that there is strong spatial wind variability over the Iberian Peninsula. This is characterized by the annual cycle, wind rose, wind speed histograms, as well as the temporal correlations of the mean regional series. In addition, the wind climate heterogeneity can be described as the interaction of the orography with the main atmospheric circulation types affecting the Iberian Peninsula. MM5 simulation is able to reproduce the main wind features of the wind over the Iberian Penisula, providing an important added value with respect to the driving conditions. The simulation has been used for several studies and applications. The limitations of the observational database have been inspected. The observational period is not long enough to describe the wind climatology in the western Iberian Peninsula and the inclusion more weather stations in some mountainous regions would be desirable. The simulation and observations are used to evaluate the wind power resource. A public web mapping tool for facilitating the access to wind information has been developed. In addition, the long period simulated has allowed the analysis of the wind variability during the last five decades. A decline of the wind speed during winter has occurred, associated to a decrease of cyclonic situations. On the other hand, the wind speed has increased during summer due to an enhancement of thermal circulations. The major caveat with the MM5 and WRF simulations was a systematic wind speed overestimation. The inclusion of the parameterization of the subgrid topographic effects in WRF reduces the wind speed bias. However, this scheme underestimates the wind speed during windy situations and the amplitude of the diurnal cycle, being the main disagreements during the day. The relationship of the wind speed bias with the convective velocity, the turbulent kinetic energy and the height of the boundary layer points out that the induced subgrid topographic friction is influenced by the atmospheric stability conditions. The modulation of the frictional term as a function of the stability parameters improves the reproduction of the wind speed daily cycle. However the improvement depends on the time of the year. This Thesis contributes to deepen in the knowledge of the variability of surface winds over the Iberian Peninsula by means of observations and regional climate models. This work also represents and advance in atmospheric simulations because drawbacks associated with the simulated winds are improved by implementing new physics schemes in mesoscale models.

Abstract:
La tesis trata el tema del desarrollo turístico en los parques naturales protegidos en su aplicación a los situados en el norte-interior de la Comunidad Valenciana desde la metodología estratégica. Se parte de las hipótesis de que estos parques carecen de un dinamismo turístico, que faltan productos estructurados al igual que se da un déficit en instrumentos y gestión pública, por lo tanto es necesaria una investigación que analice el sistema turístico de estos parques al igual que un estudio prospectivo que nos garantice el desarrollo turístico de los mismos. Al respecto, la investigación se estructura en tres partes con seis capítulos, siendo la primera de carácter teórico y conceptual, tratándose en la segunda el estado del sistema turístico en estos espacios naturales y ya por ultimo en le tercera se desarrolla el estudio analítico y prospectivo con la aplicación de la metodología Delphi-Likert 5, con el desarrollo de dos rondas y la participación final de 23 panelistas. La estructura y el contenido del cuestionario lo conforman dos bloques, el de análisis de partida con preguntas entorno a los recursos turísticos, factores socioeconómicos y medioambientales, la demanda turística, las infraestructuras y servicios y financiación y gestión, y un segundo bloque de carácter prospectivo analizando los factores que pueden presentar un freno en la evolución turística y las acciones para activar el desarrollo turístico sostenible en los espacios naturales protegidos, con un total de 126 ítems en los dos bloques. Respecto a los resultados, analizados los elementos del sistema turístico (recursos, oferta, infraestructuras y servicios) y los de la técnica Delphi, podemos significar que los aspectos más valorados y consensuados en la investigación han sido: la potencialidad de los recursos territoriales turísticos, la calidad de las aguas y siendo los peor valorados: la financiación y gestión publica, planteándose un reto de futuro el convertir los recursos en productos, mejorar las infraestructuras de comunicación, que los alojamientos y los servicios complementarios deben salvaguardar la autenticidad de sus espacios y la necesidad de ordenar estos espacios naturales de forma integrada en la estructura socioeconómica y medioambiental. Todos estos aspectos vienen a confirmar los planteamientos iniciales de las hipótesis.

Abstract:
This study comprised of a survey of 807 students in geosciences classes at Mississippi State University to determine the perceived level of threat from eight natural hazards: hurricanes, hail, lightning, tornadoes, earthquakes, ice storms, floods, and wildfires. Responses were analyzed to detect spatial differences in perceptions of threats across the state of Mississippi for comparison. Actual occurrences of the natural hazards and preparations for dealing with these hazards were recorded by county and MEMA districts. Threat perceptions for hurricanes, ice storms, floods, and lightning showed spatial differences, whereas threats from hail, tornadoes, earthquakes, and wildfire showed no spatial differences. All perceived threats except ice storms paralleled the actual recorded occurrences of the respective hazards spatially. Preparations for each hazard included the adoption of MEMAs Basic Plan for the entire state.

Abstract:
The dissertation research will comprise three essays on the topic of the resource curse hypothesis and its mechanisms. The phenomenon of low economic growth in resource-rich regions is recognized as the “resource curse”. These essays will contribute to an understanding of the regional resource-growth relation within a nation. Essay one tests the resource curse hypothesis at the U.S. state level. With a system of equations model, I decompose the overall resource effect to account for the two leading explanations — crowding-out and institution effects, thus investigate whether the institutions mediate the crowding-out effects. I did not find evidence of an overall negative effect on growth by resource wealth. Both the crowding-out and institution appear present, but they offset: the resource boom crowds out industrial investments, but good institutions mitigate the overall effect. Resources do reduce growth in states with low-quality institutions, including Louisiana, Oklahoma, and Texas. Essay two compares the effects of resource revenues on the economic growth and growth-related factors across Chinese provinces and American states, using panel data from 1990 to 2015. With the Instrumental Variable (IV) strategy, I show that regions with higher resource revenues grow faster than other regions in both China and the U.S. The positive resource effect is larger and more statistically significant in the U.S. Further testing impacts of three resource-related policies in China, e.g. the market price reform, the fiscal reform, and the Western Development Strategy, I show that the market price reform together with the privatization process on coal resources contribute the positive resource effect in China. Though strong and positive resource – growth relations appear in both countries, evidence also suggests consistent negative resource effects on certain growth-related factors in both countries, such as educational attainments and R&D activities. Essay three explores the schooling response to the oil and gas boom, taking advantage of timing and spatial variation in oil and gas well drilling activities. Development of cost-reducing technologies at the time of higher crude oil and natural gas prices in the early 2000s has accelerated shale oil and gas extraction in the United States. I show that intensive drilling activities have decreased grade 11 and 12 enrollment over the 14 year study window − approximately 36 fewer students per county on average and overall, 41,760 fewer students across the 15 states enrolled considered in the analysis. On average, with one additional oil or gas well drilled per thousand initial laborers, grade 11 and 12 enrollment would decrease 0.24 percent at the county level, all else equal. I investigate heterogeneous effects and show that the implied effect of the boom is larger in states with a younger compulsory schooling age requirement (16 years of age instead of 17 or 18), lower state-level effective tax rate on oil and gas productions, traditional mining, non-metro, and persistent poverty counties.

Abstract:
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior
O algodÃo jà foi a principal cultura cultivada no Nordeste, a sua produÃÃo alavancou o desenvolvimento de muitas cidades e contribuiu para o desenvolvimento da regiÃo semiÃrida. Ataque de pragas, baixas produtividades, alto custo de produÃÃo e baixa nos preÃos no mercado internacional, aliado a falta de assistÃncia tÃcnica adequada, contribuÃram para o declÃnio da cultura. Esta pesquisa tem o objetivo de estudar as alternativas mais eficazes de controle de pragas no algodoeiro agroecolÃgico, como tambÃm a organizaÃÃo coletiva dos agricultores, tendo em vista a otimizaÃÃo da produÃÃo do algodÃo em consÃcios agroecolÃgico na regiÃo do semiÃrido brasileiro. Os estudos foram desenvolvidos no campo experimental da Embrapa AlgodÃo em Barbalha-CE e no TerritÃrio do SertÃo do Araripe, estado de Pernambuco, em localidades assistidas pelo projeto algodÃo em consÃrcios agroecolÃgicos. Em Barbalha instalou-se o experimento para avaliaÃÃo dos produtos naturais, com o delineamento experimental em blocos ao acaso e com quatro repetiÃÃes, representado por seis tratamentos: T1-Testemunha (sem aplicaÃÃo), T2-Pimenta malagueta, T3-Caulim, T4-AzamaxÂ, T5-Rotenat e T6-PironatÂ. Os produtos foram aplicados a cada sete dias, seguidos de avaliaÃÃes tambÃm semanais, considerando o efeito dos tratamentos sobre a ocorrÃncia dos insetos pragas do algodoeiro e de seus inimigos naturais. O caulim foi o mais eficiente no controle do bicudo do algodoeiro, Anthonomus grandis Boheman, atrasando o inÃcio da infestaÃÃo. A pimenta malagueta nÃo foi eficiente no controle das pragas. Os produtos aplicados nÃo influenciaram na presenÃa de inimigos naturais, nem a produtividade e precocidade da cultura. Os agricultores aplicam diversos produtos naturais encontrados na prÃpria comunidade, participam de todas as etapas de produÃÃo, certificaÃÃo orgÃnica e comercializam seus produtos agroecolÃgicos a um preÃo justo, fortalecendo a organizaÃÃo coletiva. A maior renda à proveniente da venda da pluma do algodÃo orgÃnico, sendo a mamona, amendoim e gergelim boas alternativas para geraÃÃo de renda. Nas capacitaÃÃes dos agricultores o saber local à valorizado, provocando autoestima nas comunidades. A diversificaÃÃo permite ao agricultor um uso mais eficiente da terra, maior geraÃÃo de renda, seguranÃa alimentar e garantia de alimentaÃÃo para os animais. O cultivo do algodÃo em consÃrcios agroecolÃgicos pode representar uma possibilidade de reintroduÃÃo desta cultura na agricultura familiar do semiÃrido brasileiro.
The cotton was once the main crop grown in the Northeast, its production boosted the development of many cities and contributed to the development of the semiarid region. Pest attack, low productivity, high production costs and low prices on the international market, coupled with the lack of adequate technical assistance contributed to the decline of culture. This research aims to study the most effective alternatives for pest control in cotton agroecosystem, as well as the collective organization of farmers, with a view to optimizing the production of cotton in agroecological fellow members in the Brazilian semiarid region. The studies were carried out in the experimental field of Embrapa Cotton Barbalha-CE and Territory Hinterland Araripe, state of Pernambuco, in locations served by the project consortia agroecological cotton. Barbalha settled in the experiment for evaluation of natural products, with the experimental design of randomized blocks with four replicates, represented by six treatments: T1-Control (without application), T2-Pepper chili, Kaolin-T3, T4- Azamax Â, Rotenat Â-T5 and T6-Pironat Â. The products were applied every seven days, followed by weekly assessments also considering the effect of treatment on the occurrence of insect pests of cotton and their natural enemies. The kaolin was the most effective in controlling the boll weevil, Anthonomus grandis Boheman, delaying the onset of infestation. The chili was not effective in controlling pests. The products applied did not influence the presence of natural enemies, nor productivity and precocity of culture. The farmers apply various natural products found in the community, participate in all stages of production, organic certification and market their agroecological products at a fair price, strengthening the collective organization. The higher income is from the sale of organic cotton lint, with castor, groundnut and sesame good alternatives for income generation. In the training of farmers local knowledge is valued, causing self-esteem in the communities. Diversification allows farmers to more efficient use of land, greater income generation, food security and ensuring food for the animals. The cultivation of cotton in agroecological consortia may represent a possible reintroduction of this crop in the semiarid Brazilian family farming.

Abstract:
This is a general regional research design for the prehistoric archaeological resources of the Upper White River Drainage region of east-central Indiana. Following the example of McGinsey, Davis, and Griffin (1968), this design consists primarily of research problems, questions, and hypotheses suggested by the current state of the regional data base and the pertinent literature. These research problems are organized into three basic groups which represent the goals of the discipline of archaeology (that is, the study of culture history, extinct lifeways, and culture process). These groups are themselves expressed as a hierarchy to demonstrate the relative significance of the problems expressed in each. When used as part of a greater research design process (including more specific designs) this design has the potential to contribute to the scientific rigor as well as the efficiency of archaeological research carried out in this region.

Abstract:
Com o crescimento do ecoturismo no Brasil, iniciaram a ser implantados vários empreendimentos turísticos na Amazônia, principalmente nas proximidades da cidade de Manaus, este acontecimento fez com que a utilização de recursos naturais disponíveis na região, como folhas de palmeiras nativas e espécies de madeira, voltassem a ter grande emprego como material de revestimento nas coberturas destas edificações. E em contrapartida, raros são os estudos das variáveis que interferem no projeto, na aplicação e na manutenção destes materiais na construção civil. Em vista disto, este trabalho tem o objetivo de fazer um resgate sistemático das técnicas construtivas das coberturas de alguns Hotéis de Selva visitados no Estado do Amazonas. Entrevistas com construtores locais, observações das construções \"in loco\" e a análise das bibliografias levantadas, ajudaram a identificar os principais problemas encontrados, propondo a partir daí alternativas de detalhes projetuais e de execução, diretrizes de manutenção e reparos para garantir um maior desempenho destas envoltórias frente aos impactos da agressividade da Floresta Amazônica, tendo como parâmetros fundamentais a Exeqüibilidade e a Durabilidade do sistema escolhido garantindo assim uma maior adequação da edificação ao meio-ambiente em questão.
With the increase of the Brazilian ecotourism start to be implantated many ecolodges in the Amazonian Forest (especially nearby Manaus City), this happening brought back the large utilization of natural resource disposables on the region, like native palm leaves and several wood species, for the roof sheathing of these tropical hotels, on the other hand, there are very few technic studies about the variables that interfere on the architectonic project, the aplication and the maintenance of these constructive materials. In this aspect, this work has the purpose to make a systematic ransom of the vernacular constructive technics that were used on some hotels existing in the Amazonas State. From the bibliographies that were consulted, the interviews made with the constructors and from the observations of the lodges\' roofs on site, helped to identity the main problems that were found, proposing from then alternatives of projectual and constructive details, maintainable and treatment directives to ensure a better durability of the roofs against the impacts of the environment\'s aggressiveness, having as fundamental parameters the buildbility and the durability of the constructive system chosen and assuring a greater adaptation of the edification at the Amazon too.

Abstract:
This thesis critically examines exports of Iranian natural gas to regional and international markets. Owning the world’s 2nd largest proven natural gas reserves, Iran can potentially be considered a major gas exporter. Yet, stringent international sanctions, coupled with domestic politicisation of the industry and lack of an ‘attractive’ investment framework, have made Iran unable to capitalise its huge natural gas potential both in domestic and international markets. In this research, a multidisciplinary approach is adopted to examine the main challenges hampering Iran’s ability to become a major gas exporter. These challenges range from political and legal to economic and fiscal. In this thesis, the extent to which the Iranian gas industry is affected by progressive international sanctions, particularly as a result of U.S. pressures, is considered extensively. It appears that U.S. and international sanctions have had detrimental impact on the development of the Iranian petroleum industry through limiting Iran’s access to financial institutions and technologies. In addition, in Iran the constant policy struggle between the need for foreign investment and technology in the petroleum sector on one hand, and the sentiment towards foreign exploitation on the other, is analysed in terms of impact of political challenges in the development of Iran’s natural gas industry. The legal and fiscal terms of buyback contracts as the only available contractual framework for development of the upstream petroleum sector is also reviewed as a part of the evaluation of the ‘attractiveness’ of Iran’s investment framework. This research offers second thoughts on the over-estimated role of law in development of natural resources and illuminates the importance of other factors, including policy making and governance institutions, in attracting foreign investors and the development of the petroleum sector. In the discussion about the development of Iran’s natural gas industry, subsidies are also identified as economic challenges, deterring foreign investors, causing wasteful consumption and creating an inflated domestic market. Two years into the subsidies reform in Iran, the plan has fallen short of achieving its objectives, including controlling domestic energy consumption and freeing up capital to be re-invested in the petroleum industry, mainly as a result of deteriorating economic conditions and Government mismanagement. The issue of supplying gas to domestic or export markets in the light of the country’s current limited production capacity has turned into a major political debate between the Parliament and the Government resulting in failure to fully meet its supply commitments to either market. Inability to produce adequate volumes of gas and its ‘ambitious’ gas expansion policies both in domestic and international markets, has forced the country to import gas from Turkmenistan. The unexpected title of ‘a net gas importer’ for a country with the 2nd largest gas reserves in the world, has raised many questions over the country’s ability to substantially contribute to the growing global gas market. In this thesis, attempts are also made to highlight the social and economic benefits of allocating gas to domestic and export markets. However, conducting a solid economic analysis is not possible, as first of all, such an analysis is beyond the scope of this thesis, and secondly the required data and statistical material is not available or accessible. This research suggests that given the country’s huge domestic market, industrialisation targets, young population and the necessity for job creation, as well as country’s dependence on gas re-injection into oilfields to maintain the oil production, Iran may not want to be “the next Qatar” in terms of exports. Available data suggest that gas export is not the most beneficial economic outcome for Iranian gas; and for all of the foregoing reasons, and even if sanctions are removed, it would take Iran 15-20 years to develop such a major export capability. This thesis offers recommendations to policy makers to conduct comprehensive economic analyses over costs and benefits of allocating gas to domestic and export markets, while giving due consideration to the pressing issue of ‘welfare maximisation’ and distributional impact of consuming gas domestically.

Abstract:
Various adaptation and mitigation strategies have been explored to cope with changes in the climate. Estimating these strategies impacts on the local economy is one of the growing and pressing issues for the management of natural resources. This thesis consists of three parts and aims to contribute to regional economic studies by analyzing: (1) the economic impact of solar energy facilities, (2) the level of virtual water flow and the effectiveness of scenarios to mitigate water resource shortage, and (3) the impact of climate change on agriculture through a Ricardian approach weighted by stream flow connectivity. As an increasingly adopted renewable energy resource, solar power has a high potential for carbon emission reduction and economic development. In the first essay the impacts on jobs, income, and economic output of a new solar power plant are calculated in an input-output framework. The contribution is twofold. First, we compare the multipliers generated by the construction and operation/maintenance of a plant located in California with those that would pertain had it been built in Arizona. Second, we point out the differences in the results obtained with the popular IMPLAN software from those obtained with the solar photovoltaic model of JEDI. The second essay focuses on water use in Arizona. As much as 73% of the state's scarce water is used by a single sector: crop production. Because 79% of Arizona's crop production is consumed outside the state, this means that, 67% of the water available in the state is being exported to the rest of the country and abroad. This should be of major concern for a state expected to see its population grow and its climate get drier. Using input-output techniques we explore three scenarios aimed at saving 19% of the water available. This figure is based on the results of the first of the scenarios that explores how much can be saved through improving the efficiency of the current irrigation system. The second scenario shows that equivalent water savings could be reached by a twenty-seven-fold increase in the price of water. The third scenario shows that a 19.5% reduction in crop exports could conserve an equal amount of water. The model results suggest that the least costly solution is a more efficient irrigation system, while export reduction is the second best choice. The third and final essay offers an extension of the well-known Ricardian model of agrarian economic rent. In spite of its popularity among studies of the impact of climate change on agriculture, there has been few attempts to examine the role of interregional spillovers in this framework. We remedy this gap by focusing on the spatial externalities of surface water flow used for irrigation purposes and demonstrate that farmland value—the usual dependent variable used in the Ricardian framework—is a function of the climate variables experienced locally and in upstream locations. This novel approach is tested empirically on a spatial panel model estimated across the counties of the Southwest USA for every five-year period from 1997 to 2012. This region is one of the driest in the country, hence its agriculture relies heavily on irrigation with the preponderance of the sources being surface water transported over long distances. The results highlight the significant role of irrigation spillovers and indicate that the actual impact of climate change on agriculture and subsequent adaptation policies can no longer overlook the streamflow network.

Abstract:
La presente investigación tiene como eje principal el estudio detallado de las mineralizaciones y la geología de un área del Macizo del Deseado con características geológicas y metalogénicas únicas. La elección del área del El Tranquilo o también conocido como “anticlinal” El Tranquilo, como zona de estudio, se ha basado en el reducido conocimiento y la presencia características atípicas en las mineralizaciones y la escasa representación, en el Macizo del Deseado, de las rocas y unidades geológicas aflorantes. La investigación ha sido realizada en tres etapas: una primera con recopilación de antecedentes y trabajo de campo, una segunda analítica con trabajos de laboratorio y una tercera etapa interpretativa. Se realizó el procesado de imágenes satelitales (TM, SPOT, IKONOS) y se ejecutaron mapeos geológico-estructurales de detalle y semidetalle (con elaboración de una cartografía digital), descripción de testigos de sondeos (gran parte de los 30.000 metros de las perforaciones ejecutadas en la propiedad minera), se realizaron estudios petrográficos, calcográficos, de rayos X, determinaciones geoquímicas, estudios de inclusiones fluidas, de microscopía electrónica, microsonda electrónica, determinaciones geocronológicas y análisis de isótopos estables e inestables. Además se participó de otros trabajos complementarios realizados durante las distintas etapas de exploración minera, tales como geoquímica de suelos, muestras de trincheras y relevamientos magnetométricos y geoeléctricos terrestres y la interpretación, para la zona de trabajo, de estudios previos de magnetometría aérea y líneas sísmicas. El área del “anticlinal” El Tranquilo, está caracterizada por la presencia de rocas y unidades geológicas con escasa representación en el Macizo del Deseado, y representa una “ventana geológica” que permite el estudio del intervalo Triásico superior - Jurásico inferior, períodos que se encuentran poco expuestos en esta provincia geológica. La secuencia estratigráfica de este sector se inicia con las sedimentitas continentales, areniscas a areniscas conglomerádicas con intercalaciones de pelitas, del Grupo El Tranquilo, del Triásico medio a superior (Jalfin y Herbst 1995). Por encima, se presentan las rocas volcaniclásticas de la Formación Roca Blanca (Herbst, 1965), del Jurásico inferior. Esta es la litología más desarrollada en el área y está compuesta por tufitas, areniscas y sabulitas ricas en componentes volcánicos. Intruyendo a las sedimentitas continentales y a las tufitas, se disponen rocas básicas a intermedias del Jurásico inferior, que se presentan como filones capa de diabasa en el sector este del área y como pórfidos andesíticos de formas subcirculares en el sector noroeste, de la Formación Cerro León (Panza, 1995 y de Barrio et al., 1999). En los sectores norte y noreste del área afloran volcánitas del Jurásico medio a superior, basaltos y andesitas de la Formación Bajo Pobre, y en el sector sudoriental pequeños asomos de ignimbritas riolíticas del Grupo Bahía Laura (Panza, 1995). Estas unidades se encuentran parcialmente cubiertas por el Basalto Las Mercedes del Cretácico superior y el Basalto Cerro del Doce correspondiente al Eoceno (Panza, 1982) y finalizan esta secuencia sedimentos modernos, aluviales, coluviales y de bajos. En la presente investigación se determinó la presencia de niveles ignimbríticos ácidos y coladas basálticas intercaladas en las tufitas de la Formación Roca Blanca. A partir de las edades obtenidas, relaciones estratigráficas y composición se desvincula a los intrusivos dioríticos de la Formación Cerro León y se los asocia con el magmátismo de la Formación La Leona (Jurásico inferior). Los basaltos aflorantes en el área presentan características de basaltos continentales que se corresponden a los primeros indicios del magmatismo sinextensional jurásico y representan magmas básicos de origen mantélico que alcanzaron la superficie. Se los desvinculan de la Formación Bajo Pobre por ser ligeramente más antiguos al estar intercalados entre las tufitas de la Formación Roca Blanca (Jurásico inferior) y por presentar diferentes características isotópicas y petrogenéticas. Se define así una nueva unidad formacional para estas rocas denominándolas Formación El Piche. Los pórfidos andesíticos de la Formación Cerro León y las andesitas de la Formación Bajo Pobre presentan similitudes geoquímicas, isotópicas, petrogenéticas y edades semejantes, por lo que se interpreta un mismo origen para estas rocas, siendo los pórfidos andesíticos partes de los conductos de emisión de las coladas andesíticas. A diferencia del resto del Macizo del Deseado donde predomina casi por completo deformación con comportamiento netamente frágil, en el área de estudio se reconoció deformación tanto dúctil como frágil en las secuencias triásicas y jurásicas. Los rasgos estructurales más sobresalientes son: un domamiento regional de entre 15 a 20 km de diámetro, definido por Di Persia (1956) como “anticlinal” El Tranquilo, domamientos y plegamientos con dimensiones menores a 1 km localizados dentro de la antiforma regional, un sistema de fracturas radiales asociado al domamiento y la falla El Tranquilo con un sistema de vetas controladas por fallas. Se determinó que el “anticlinal” El Tranquilo, se formó por el emplazamiento de un cuerpo intrusivo no aflorante del orden de 8 a 10 Km de diámetro y profundidad mínima hasta su techo de 1400 m, subyaciendo al Grupo El Tranquilo y a la Formación Roca Blanca, y generando por su intrusión, el domamiento regional y los domamientos y plegamientos con dimensiones menores a 1 km localizados corresponde a una deformación producida por lacolitos o stocks no aflorantes. En el área de estudio se reconocieron gran cantidad de mineralizaciones, las que totalizan ~80 km lineales de vetas, ubicadas principalmente en el sector central del área. Las vetas se concentran hacia el este de la estructura regional, la falla El Tranquilo, son subparalelas a esta estructura y están emplazadas en las tufitas de la Formación Roca Blanca y pelitas y areniscas del Grupo El Tranquilo. Se han discriminado dos tipos distintos de vetas según su composición y expresión superficial, vetas formadas por importantes zonas de oxidación que representan la expresión superficial de vetas de sulfuros, y vetas, brechas hidrotermales, vetillas y stockworks formados principalmente por cuarzo. A partir de las distintas características observadas y datos obtenidos (composición, signatura geoquímica, mineralogía, datos de inclusiones fluidas, isótopos, controles estructurales y litológicos y edades) se ha podido diferenciar dos estilos de mineralización. La mineralización polimetálica que presenta una compleja mineralogía de sulfuros asociada a una signatura geoquímica de In, Cu, Au, As, Sn, W, Bi, Zn, Pb, Ag, Cd y Sb. Las temperaturas y salinidades de los fluidos indican un sistema epitermal para la formación de estas vetas. Su génesis esta vinculada a los cuerpos intrusivos dioríticos reducidos por sedimentos ricos en materia orgánica, concentrando en los fluidos hidrotermales In, Sn, Ag, W, Bi. Se define a esta mineralización como un depósito epitermal vetiforme polimetálico rico en In semejante a los depósitos de Japón y Bolivia. Las características de esta mineralización y la edad Jurásica inferior (193 Ma) confirman la presencia de un nuevo tipo de deposito epitermal que difiere del clásico modelo de baja sulfuración del Macizo del Deseado y que no se encuentra asociado al importante volcanismo bimodal del Jurásico medio a superior (Complejo Bahía Laura), como la mayoría de las mineralizaciones del Macizo del Deseado. Este hecho potencia el hallazgo de otros tipos de depósitos epitermales polimetálicos, asociados a otras rocas y con diferentes asociaciones metalogénicas. La mineralización argentífera está formada por cuarzo, carbonatos y en menor medida sulfuros y sulfosales con una signatura geoquímica de Ag (Au), Pb, Cu y Zn. Las temperaturas y salinidades de los fluidos indican un sistema epitermal para la formación de estas vetas. Su génesis está vinculada al magmatismo intermedio de las Formaciones Cerro León y Bajo Pobre, atribuyéndole una edad Jurásica media (168 Ma). Según sus características esta mineralización puede ser definida como un depósito epitermal de sulfuración intermedia. Esta mineralización también representa una variación en el modelo de baja sulfuración del Macizo del Deseado, pero está genéticamente asociada al volcanismo bimodal del Complejo Bahía Laura (Fm. Bajo Pobre) por lo que podría incluirse dentro de las mineralizaciones de la Provincia auroargéntifera del Deseado.

This study aims to discuss the insertion of regional environmental knowledge in the program contents of private, state and municipal scholar curriculum, and to verify the relationship between the regional environmental knowledge and the educational system through a diagnostic study about the regional environment represented by the Araguaia River and considering ten schools (250 students and ten teachers) of the Elementary level schools (Cycle III - stage H) of the Municipal Educational Network of Goiania, State of Goiás. The results suggest that the different scholar curriculum includes the regional environmental aspects but the criterion to determine these is an attribution of scholar teachers. In relation to the students it was possible to verify the influence of the media in the conception of concepts or prejudices, the presence of fragmented school curriculum with a strong disciplinary structure, the concern with didactic book and the absence of scholar projects related to the regional environment, particularly to the Araguaia River or the Cerrado biome.
Este estudo objetiva discutir a inserção do conhecimento ambiental regional nos programas dos currículos das escolas privada, estadual e municipal. Pretende-se também verificar a relação entre o conhecimento ambiental regional e o sistema educacional por intermédio de um estudo diagnóstico referente ao ambiente regional, representado pelo rio Araguaia, considerando 250 alunos de dez escolas de Ensino Fundamental (Ciclo III etapa H) da Rede Municipal de Educação de Goiânia, estado de Goiás. Os resultados indicam que as diferentes redes de ensino inserem o ambiente regional nas diretrizes curriculares, porém o critério de determinar as especificidades regionais a serem abordadas fica a cargo dos professores. A respeito dos alunos foi possível verificar a influência da mídia como formadora de (pré)conceitos, a presença de currículos escolares ainda fragmentados com uma estrutura fortemente disciplinar, a preocupação com conteúdos do livro didático e a ausência de projetos escolares referentes ao ambiente regional, mais especificamente ao rio Araguaia ou bioma Cerrado.

Abstract:
La presente tesis consiste en la elaboración del Plan Estratégico para la sustentabilidad del ecosistema del Perú al 2027 y está enmarcado en el modelo secuencial del proceso estratégico elaborado por el Dr. Fernando D’Alessio Ipinza. La finalidad del planeamiento es mejorar el Índice del Progreso Social enfocado en los cuatro pilares de la sustentabilidad del ecosistema respecto a la huella ecológica, hectáreas reforestadas, aire contaminado en zonas urbanas y aguas residuales tratadas. El Índice de Progreso Social Regional Perú 2016 registró en veinte de sus regiones índices menores de 45 puntos lo cual representa una calificación de nivel muy bajo, las otras seis regiones llegan a índices entre 46.48 y 53.86, los cuales son calificados con un nivel bajo respecto de países como Suiza y Noruega, con niveles mayores de 85 puntos, lo que representa niveles muy altos. El Plan Estratégico ha establecido objetivos de largo plazo para alcanzar el nivel medio alto para los próximos diez años basados en los lineamientos económicos, sociales y cuidado del medio ambiente con la finalidad de ser un referente de la región de Latinoamérica y el Caribe con respecto al cuidado y preservación del medio ambiente sin afectar los recursos naturales de las generaciones futuras. La finalidad es que la población del Perú habite en un medio ambiente saludable, cumpliendo con las normativas y lineamientos ambientales

Abstract:
Recent trends and research indicate a continuous decrease in civic involvement that impacts skills and abilities of individuals to participate in public decision-making in a meaningful way. Evidence indicates that student involvement in the public participation process can increase civic participation as adults. Gaps in the literature indicate a need to identify ways to increase student involvement in the public participation process, and to improve the process overall. Using a mail survey instrument, two groups in Arizona--planners and teachers grades 4 through 12--were queried to determine what methods are currently used to increase civic awareness and participation, and what each group needs to involve students more often in the public participation process. Survey results are compared between groups to understand compatibility of methods, and opportunities for planner/teacher partnership. Results indicate similarities in methods used but incompatibility regarding preference or frequency of use of methods. Both groups strongly agree there is student benefit from participation in the public planning process. They also agree that student involvement adds value to the planning process. Both groups' results suggest a need to learn more about how to involve students in the public participation process Two case studies are used to make a case for teacher-lead student involvement in the public participation process. Four goals from the environmental education field are modified and proposed, as an approach to structure effective student involvement.

Abstract:
Los desastres naturales generan daños importantes, desequilibrios sociales y económicos, en donde a mayor subdesarrollo mayores efectos. En Chile, las catástrofes naturales constituyen fenómenos recurrentes en la historia del país, debido a las características geológicas, climáticas, morfológicas y topográficas del territorio nacional. El área de estudio corresponde al corredor de comercio Las Leñas, ubicado en el valle del río Cachapoal, en la zona de media y baja montaña, en donde se identificaron las amenazas relacionadas a remoción en masa, inundaciones y sismos principalmente. Este corredor fue seleccionado por el Ministerio de Obras Públicas por sus favorables oportunidades de realización, además de estudios que indican que posee menor nivel de riesgo global (físico y socioeconómico). Los objetivos de este estudio son caracterizar y evaluar la vulnerabilidad global del corredor de comercio Las Leñas, en su tramo de media y baja montaña; para lo cual se realizó una evaluación multicriterio, en donde se establecieron los pesos de cada amenaza para el área de estudio, con una posterior expresión espacial a través de SIG. La amenaza natural a la que se encuentra mayormente expuesto el corredor de comercio, es a remociones en masa, esto principalmente a la gran cantidad de material que proviene principalmente de la alta montaña y de las vertientes que se encuentran alrededor del corredor. El detonador principal de amenazas son las precipitaciones que desencadenan inundaciones y deslizamientos, preferentemente en la época invernal. El riesgo de este corredor de comercio se puede determinar como riesgo tolerable después del desarrollo de medidas de mitigación para ciertos sectores.

Abstract:
Buildings, especially in hot climates, consume a lot of energy when people want to be comfortable inside them, which translates to very expensive fees each month. The most innovative response to this problem is renewable energy, that is used, in this case, to run mechanical HVAC systems. Renewable energy is the solution for many problems, but to avoid urban heat islands when using excessive HVAC systems (powered by renewables), and to solve thermal comfort-related problems, there has to be other solution. The major challenge to find it would be to have a change of thinking process. If a building in a hot-arid region uses natural processes to emulate the functions of HVAC systems, and the proper passive strategies, then, it will provide thermal comfort to its users, diminishing the need of a mechanical system. This hypothesis will be carried out by extracting the natural processes found in a specific case in nature, applying them into a building's design, and then simulating its energy efficiency with the adequate software. There will be a comparison of the same proposed building without the natural processes, to have tangible numbers showing that these proposed strategies, in fact, work. With explanatory detailed diagrams and the energy analysis, the hypothesis could be proven correct or incorrect. The significance of this approach relies on the proximity to the natural processes that have been working in different aspects of life since the beginning of time. They have been there all the time, waiting until architects, engineers, and people in general use them, instead of making more new energy-using inventions. By having the numbers from a conventional building and the ones of the proposed building, and the right environmental diagrams, the experiment should be valid. In the near future, there should be more research focused on nature and its processes, in order to be able to reduce the use of mechanical systems, and with that, reduce the energy use and the carbon footprint.

As formas naturais do relevo costeiro são resultantes da atuação e interação de processos continentais, oceânicos e atmosféricos. Dentre as diversas feições costeiras destacam-se as falésias e, nesta tese, serão discutidas estas feições esculpidas na Formação Barreiras, sendo esta uma vasta área sedimentar que se estende desde o estado do Rio de Janeiro até o estado do Amapá. Há um grande conjunto de elementos em interação atuando na morfogênese e evolução das falésias e estes são considerados dentro de uma perspectiva de análise sistêmica, sendo estes agrupados e caracterizados como elementos de um Sistema Natural, considerando-se o sistema como um conjunto formado por materiais, processos e formas, tratados, nesta tese, como um sistema geomórfico dinâmico com entrada (inputs) e saída (outputs) de energia e materiais identificáveis, dirigidos e controlados pelas condições ambientais, no qual inúmeros tipos de processos ocorrem simultaneamente. Estudos teóricos e de campo foram realizados em Beberibe-CE, Mucuri-BA e Tibau do Sul-RN e possibilitaram a observação e identificação de características e indícios da morfogênese e evolução das falésias, permitindo a proposição de uma classificação, dentro de um quadro regional da Formação Barreiras, destas feições em: 1) falésia precedida por praia; 2) falésia não precedida por praia.
Natural forms of coastal relief are the result of the action and interaction of continental, oceanic and atmospheric processes. Among various coastal features, cliffs stand out and in this thesis, we discuss these features carved into Formação Barreiras, which is a vast sedimentary area stretching from Rio de Janeiro to Amapá State. There is a large set of elements in interaction taking part in the morphogenesis and in the evolution of cliffs which are considered here within the perspective of a systemic analysis. These elements are classified and characterized as elements of a \"Natural System\", considered system as a whole formed by materials, processes and forms, treated, in this thesis, as a dynamic geomorphic system with inputs and outputs of strenght and materials identifiable, directed and controlled by environmental conditions, in which numberless types of material processes occur simultaneously. Theoretical and field studies performed in Beberibe-CE, Mucuri-BA and Tibau do Sul-RN, allowed us to observe and identify characteristics and evidences of cliffs morphogenesis and evolution, making possible we propose a classification of these features, within a regional framework of Formação Barreiras: 1) cliffs preceded by a beach; 2) cliffs not preceded by a beach.

The effort to go through the various forms of intentionality, in the constitution of objects of nature and spirit, is the goal for which they were produced in the complex descriptions Ideas II (1913 - 1922). The concept of regional ontology, which is treated Ideas I (1913) from the standpoint of its more general principles, is applied to particular problems in Ideen II, to demonstrate that reality and the characteristic features of each kind of objectivity (natural and spiritual) depend on intentionality. This is essential both to be donated, and to be recognized in its own ontological status. Our work focused on spiritual objectivity, and found himself thus engaged with themes that are present in the Cartesian Meditations (1931). The approach of spiritual objectivity depends on the exposure of the distinction between causality and motivation. Given the importance of the second, also requires more detailed analysis of the concepts of the spiritual world, empathy, intersubjectivity and expression. In the constitution of spiritual objectivity, its actually admits "predicates meaning" unlike natural objectivity. And our hypothesis is that the level of transcendental spirit, stated by Husserl, can only be sustained by a sense of ego, apparently secondary, whose predispositions of consciousness has essential debt with the body (Leib) and attitudes of parallelism
O esforço de percorrer as várias formas de intencionalidade, presentes na constituição dos objetos da natureza e do espírito, é a meta para a qual foram produzidas as complexas descrições em Ideias II (1913 1922). O conceito de ontologia regional, que é tratado Ideias I (1913) do ponto de vista dos seus princípios mais gerais, é aplicado a problemas particulares em Ideen II, no sentido de demonstrar que a realidade e os traços característicos de cada espécie de objetividade (natural e espiritual) dependem da intencionalidade. Essa é indispensável tanto para serem doados, quanto para serem reconhecidos em seu estatuto ontológico próprio. O nosso trabalho se concentrou na objetividade espiritual, e se viu, dessa forma, comprometido com temas que estão presentes nas Meditações Cartesianas (1931). A abordagem da objetividade espiritual depende da exposição da distinção entre causalidade e motivação. Pela importância da segunda, também exige a análise mais detalhada das noções de mundo espiritual, empatia, intersubjetividade e expressão. Na constituição das objetividades espirituais, a sua realidade admite predicados de significação , ao contrário da objetividade natural. E nossa hipótese é a de que o nível transcendental do espírito, afirmado por Husserl, só se sustenta mediante uma noção, aparentemente secundária, de ego, cujas predisposições de consciência contém uma dívida essencial com o corpo-próprio (Leib) e com o paralelismo das atitudes

Abstract:
The resource curse thesis states that countries with an abundance of natural resources tend to experience lower economic growth rates. However, does this theory apply also to the regional level? The purpose of this thesis is to both test the natural resources curse theory at the regional level in Sweden, as well to examine if different types of natural resource dependencies appear to have the same effect on regional income growth in the country. The methodological approach builds on an econometric (OLS) analysis using two different panel datasets over time intervals, 2000-2017 and 2007-2017, respectively. The results from one of the datasets suggest that the dependency on natural resources does not appear to affect Swedish counties' income growth, nor is there any difference in the impact on income growth from different types of natural resources. However, the corresponding results from the other dataset suggest a positive relationship, although these results are not robust across various model specifications.
Teorin om naturresursernas förbannelse förutspår att länder med ett överflöd av naturresurser kommer att ha en lägre ekonomisk tillväxt. Stämmer även denna teori på regional nivå? Syftet med denna studie är att undersöka om resursförbannelsen existerar på regional nivå i Sverige samt att undersöka om olika typer av naturresurser har olika påverkan på den regionala inkomstutvecklingen i landet. Metodiken för att besvara detta bygger på en ekonometrisk (OLS) analys med två olika paneldataset med skilda tidsintervaller, 2000–2017 och 2007–2017. De resultat som baseras på det ena datasetet visar att naturresurser inte har en påverkan på inkomstutvecklingen på svensk länsnivå, samt att olika typer av naturresurser inte heller har en påverkan på den regionala inkomstutvecklingen. Det andra datasetet påvisar dock att det finns ett positivt förhållande mellan regional inkomstutveckling och naturresurser, men detta resultat är inte robust.

Abstract:
O ácido elágico é um composto fenólico responsável por diversas atividades biológicas tais como antioxidante e/ou anticarcinogênica e está presente algumas frutas e nas nozes. As bagas, mais conhecidas como berries e a romã são as fontes mais conhecidas de ácido elágico, porém, não são alimentos usualmente consumidos na dieta brasileira. Desta forma, o objetivo deste trabalho foi realizar um screening em frutas e sementes em relação aos seus teores de ácido elágico e a partir do screening, selecionar uma fruta para estudo dos teores de ácido elágico durante sua maturação. Um total de 35 variedades de frutas (21 famílias botânicas) e 11 tipos de sementes (9 famílias botânicas) foram avaliadas por CLAE quanto ao teor de ácido elágico livre e total. O ácido elágico total foi quantificado após hidrólise dos elagitaninos utilizando TFA 2N a 120ºC por 90 minutos. O ácido elágico foi encontrado em 10 das 35 variedades de frutas e em 3 das 11 variedades de sementes avaliadas. Em frutas, seus teores variaram entre 0,28 e 8,5 mg/100 g b.u. de ácido elágico livre e entre 21,5 e 311 mg/100 g b.u. de ácido elágico total, sendo a jabuticaba, a grumixama e o cambuci (família Myrtaceae) as frutas que apresentaram os maiores teores. Entre as sementes, 3 amostras apresentaram entre 0,37 e 41 mg/100 g e entre 149 e 823 mg/100 g respectivamente de ácido elágico livre e total, sendo as nozes e a pecan (família Juglandaceae), as principais fontes. Em frutas que apresentaram ácido elágico, realizou-se ainda uma caracterização quanto aos teores de fenólicos totais, vitamina C e capacidade antioxidante. A partir destes resultados, a jabuticaba foi a fruta selecionada para estudo dos teores de ácido elágico em função dos estágios de maturação, onde se observou em todas as porções casca, polpa e semente, decréscimo nos seus teores com a maturação.
Ellagic acid is a phenolic compound present in fruis and nuts which acts as potent anti-oxidant and anti-carcinogenic. Berries and pomegranate are the main sources of ellagic acid, however, these fruits are not commonly consummed in the Brazilian diet. Thus, the objective of this work was screened fruits and nuts for content of ellagic acid and according to this, one fruit was selected for studing the ellagic acid content during maturation. Thirty five varieties of fruits (21 bothanical families) and eleven nut samples (9 bothanical families) were evaluated for content of ellagic acid by HPLC. Total ellagic acid content was quantified after ellagitannins hydrolysis using 2N TFA 120ºC for 90 min. Ellagic acid was detected in 10 of 35 fruits and in 3 of 11 nuts. The content of free ellagic acid in fruits varied from 0.28 to 8.5 mg/100 g (FW) and the total ellagic acid varied from 21.5 to 311 mg/100g (FW), whereas jabuticaba, grumixama and cambuci (Myrtaceae family) showed higher ellagic acid content. Among nuts, three samples showed free and total ellagic acid content ranging from 0.37 to 41 and from 149 to 823 mg/100 g (FW) respectively. Among them, walnut and pecan (Juglandaceae family) were the main sources. Total phenolic content, antioxidant capacity and ascorbic acid content were also evaluated in fruits which contained ellagic acid. According these results, jabuticaba was selected for determine the content of ellagic acid during maturation and it was observed decreasing in all parts - skin, pulp and seed - during maturation.

Abstract:
This thesis is about how people develop attachments to places, and what this means for natural resource management. The concept of ‘sense of place’ is generating strong interest in the domain of natural resource management. In particular, the concept offers considerable potential as a way of integrating social, ecological and economic dimensions of environment. This makes the concept highly relevant to an emerging agenda from a range of disciplines and management approaches concerned with the links between social systems and natural systems at local and regional scales (Berkes and Folke 1998; Cheng Kruger and Daniels 2003; Plumwood 2002).¶ Recent interest in place has led to a research agenda for exploring how this concept can play a greater role in resource management (Cantrill and Senecah 2001). Central to this research agenda are questions of how attachments to places are influenced and how sense of place changes over time. In response to the emerging role of sense of place in natural resource management and the research agenda for exploring this concept, this thesis is concerned with three questions: what are the key influences on sense of place?; what is the relationship between sense of place and activities in practice?; and how do people learn about places and respond to change? To explore these questions, the thesis presents findings from interviews with 40 participants in case studies of the Atherton Tablelands and Woodstock, north Queensland. The research employed a purposeful sampling design with the aim of capturing as many different senses of place as possible within the limits of this study. Participants represented a broad range of land uses, ethnic backgrounds, ages and durations of time in the place of the interview. The data from these interviews were analysed using qualitative methods drawing on grounded theory (Charmanz 2000) and influenced by adaptive theory (Layder 1998). The research included a focus on honouring human experience (Braud and Anderson 1998), and also recognising the importance of prior research on how people develop a sense of place (Piaget 1971; Relph 1976).¶ The analysis showed how sense of place was influenced strongly by childhood experiences, both for people who grew up in the case study locations and for people who grew up elsewhere. Other strong influences on place involved living in a similar environment overseas, seeking profit and having a sense of self focussed on agricultural production. Of particular interest is that for many participants who moved to the case study locations, their sense of the Atherton Tablelands or Woodstock was well developed prior to arriving there. This implies that influencing people’s sense of place once they have arrived in a new place will be difficult. Attempts to influence people’s sense of place before they arrive, or soon after arrival, are more likely to be successful. ¶ The ways that sense of place related to practice are presented as a series of overlapping themes. These include the practice of admiring one’s place from the comfort of home, making the land produce, and engaging with a place through activities such as hunting, camping and fishing. Participants also described the practice of caring for place, such as looking after traditional country and restoring the family farm. ¶ The ways participants learned about their places focussed on their childhood experiences, learning from elders, the role of comparisons between places, and the importance of continuity of experience. Participants described very few ways of learning about their place during adulthood. One of these was seeing places under different conditions, such as during a rat plague or after a bushfire. Another was through involvement in community events such as festivals.¶ In discussing the implications of these findings for natural resource management and policy, the thesis highlights how for several participants the key influences on sense of place were tied to non-economic values. Furthermore, this thesis shows that for many people identity and place were strongly linked and this adds to research that explains why farmers may not behave in economically ‘rational’ ways (Botterill 2001a). The thesis also discusses the links between sense of place and post-productivist values in considering transitions in regional Australia identified by Holmes (2002). The findings of this thesis emphasise the potential role for environmental education during childhood to encourage learning about places. The thesis also discusses the implications of how people learn about their places during adulthood, arguing that further support for festivals and community events can play a significant role in exploring the links between social and ecological systems.¶ In conclusion, the thesis argues that the concept of place continues to offer considerable potential for understanding change in regional Australia, and in particular a grass roots shift towards post-productivist values. This role can be developed by further supporting environmental education in childhood and community events such as festivals which help us to learn about the links between ourselves and our environments.

(Survey of The Gully Vegetation in the town of Jatai in the State of Goias) The Cerrado(Savana) Domain in the Central Brazilian Plateau occupied approximately 24% of the total country’s area. Increasing deforestation and improper use of soil have caused high levels of degradation and consequent formation of gullies. In this study a survey was carried out in areas of occurrences of gullies in Jatai (GO), its geographic characterization, and the type of vegetation present in three of these gullies (Amarildo-AM, Onca-OC and Picada-PI), assessing the wealth of woody tree stratum, the floristic composition and coverage of its her-baceous sub-shrub species, in spontaneous re-vegetation and the structure of this vegetation. Of those 42 gullies found, 21 are at the Inter Planaltic Depression of Rio Claro, where there’s predominantly processes of decomposition (deteriorated). The AM is surrounded by cerradao (Savana), the OC is inserted in a matrix of pastures, with a lesser vegetative ma-trix, and the PI is surrounded by vegetation cerrada(Savana). In the survey of vegetation were allocated 10 plots (10 × 5 m = 50 m2) in each gully. Live woody tree individuals with PAP of the stem equal to, or greater than, 16 cm were identified to genus or species and family (APG III, 2009). The composition and linear coverage of herbaceous-undergrowth for intersection on the line (Canfield, 1941; 1950). Twenty three species were found in shrubby tree, distrib-uted in 17 families. Fabaceae (6) and Malpighiaceae (2), the only families that have more than one species. The herbaceous-undergrowth have 39 species, 21 families. The families Poaceae (10), Melastomataceae (4), Asteraceae (3), Cyperaceae (3) and Rubiaceae (3) have higher species richness. The greatest wealth of the herbaceous and subshrub layer was recorded in 23 species, OÇ on PI and AM,16 species each. For herbaceous and subshrub layer the similari-ties of Sorensen e Jaccard, in gullies AM and PI = 0,40 e 025; in the AM and OÇ = 0,32 and 0,19; and, in the OÇ and PI = 0,27 and 0,16. In this stratum and species with higher CR were: Gleichenia pectinata (39.7%), Andropogon Sp. 1 (17.9%), Melinis minutiflora (8.8%). And with higher FR were: Gleichenia pectinata (17.4%), Andropogon Sp. 1(11.6%), Melinis minu-tiflora (10.7%). For CR and FR the highest percentage were Gleichenia pectinata and Andro-pogon Sp. 1. The species found are ideal to be used in gullies with similar conditions. Vegeta-tion remnants and the species of greater representativeness in the survey can assist in the re-covery of degraded environments.
(Levantamento da Vegetação de Voçorocas no Município de Jataí no Estado de Goiás) O Domínio Cerrado no Planalto Central brasileiro ocupava aproximadamente 24% da área total do país. Crescentes desmatamentos e uso inadequado do solo têm causado alto nível de de-gradação e consequente formação de voçorocas. Realizou-se neste trabalho um levantamento das áreas de ocorrência de voçorocas em Jataí (GO), sua caracterização geográfica., e o tipo de vegetação presente em três destas voçorocas (Amarildo-AM, Onça-OÇ e Picada-PI), avali-ando a riqueza do estrato arbustivo-arbóreo, a composição florística e a cobertura de suas es-pécies subarbustivo-herbáceas em revegetação espontânea, e, a estrutura desta vegetação. Das 42 voçorocas encontradas, 21 estão na Depressão Interplanáltica do Rio Claro, onde predomi-nam processos de dissecação. A AM é circundada por cerradão, a OÇ inserida numa matriz de pastagens, com menor matriz vegetacional e a PI com vegetação circundante cerradão. No levantamento da vegetação foram alocadas 10 parcelas (10 × 5m=50 m2) em cada voçoroca. Os indivíduos arbustivo-arbóreos vivos com PAP do caule igual ou superior a 16 cm foram identificadas até gênero ou espécie e família (APG III, 2009). A composição e a cobertura li-near das espécies herbáceo-subarbustivas por intersecção na linha (Canfield, 1941; 1950). Fo-ram encontradas 23 espécies arbustivo-arbóreas, distribuídas em 17 famílias. Fabaceae (6) e Malpighiaceae (2), as únicas famílias que apresentaram mais de uma espécie. As herbáceas-subarbustivas com 39 espécies, 21 famílias. As famílias Poaceae (10), Melastomataceae (4), Asteraceae (3), Cyperaceae (3) e Rubiaceae (3) com maior riqueza de espécies. A maior ri-queza do estrato herbáceo-subarbustivo foi registrada na OÇ, 23 espécies, na PI e AM, 16 es-pécies cada. Para herbáceo-subarbustivo as similaridades de Sorensen e Jaccard, nas voçoro-cas AM e PI = 0,40 e 025; em AM e OÇ = 0,32 e 0,19; e, nas OÇ e PI = 0,27 e 0,16. Neste estrato as espécies com maiores CR foram: Gleichenia pectinata (39,7%), Andropogon sp.1 (17,9%), Melinis minutiflora (8,8%). E com maior FR foram: Gleichenia pectinata (17,4%), Andropogon sp. 1 (11,6%), Melinis minutiflora (10,7%). Para CR e FR as de maior porcenta-gem foram Gleichenia pectinata e Andropogon sp. 1.

Abstract:
O objetivo desta pesquisa foi investigar a relação entre a urbanização e os terrenos sedimentares e cristalinos na Região Metropolitana de São Paulo (RMSP). Para isso se intentou identificar uma área de caráter urbano e demais áreas de caráter natural. A primeira devendo ser aquela que abriga toda ou grande parte de uma forma espacial, a mancha urbana, ocorrendo sobre a maior parte dos terrenos sedimentares e cristalinos associados (de aplainamento generalizado). Já as segundas seriam as caracterizadas pelo predomínio do cinturão verde que envolve a mancha urbana, ocorrendo sobre os terrenos cristalinos não associados aos sedimentares, que não possuem aplainamento generalizado, nem abrigam pacotes sedimentares que poderiam facilitar a urbanização nos mesmos. Outro objetivo foi demonstrar que tal organização é reproduzida por ações de cunho espacial, estabelecimento e proposições de unidades espaciais ao longo do tempo. Identificada e demonstrada tal organização, intentou-se também utilizar a mesma para sugerir a divisão da RMSP em setores com diferentes prioridades para a conservação do cinturão verde. Para isso se articulou o Método Regional de Richard Hartshorne (1978), que propõe uma relação entre a Geografia Idiográfica e Nomotética, com a utilização de amostras espaciais localizadas no Município de São Paulo, bem representativas de toda a transição e diferenciação entre ambiente associado à mancha urbana e ao cinturão verde. Em cada amostra se realizou integrações espaciais específicas, da comparação das mesmas identificou-se um parâmetro associado à ocorrência da mancha urbana, e o mesmo foi associado à delimitação e configuração espacial da organização espacial pretendida. A cota 800 m correspondeu a esse parâmetro, dessa forma, as terras baixas de significância regional foram associadas à área urbana e as altas às áreas naturais. Demonstrouse que ações de cunho espacial, o eixo Leste-Oeste de expansão urbana induzida pelo poder público desde a década de 1970, bem como as unidades de proteção ambiental de diversas categorias de conservação presentes na RMSP, reproduzem tal organização espacial, a corroborando, podendo-se ainda identificar aquelas que concordaram com a mesma e poderiam ser justificadas na lógica da sociedade e não só na científica ou ambiental. Tal análise permitiu a identificação de uma organização espacial complementar que associa a expansão urbana a tipos climáticos e justifica socialmente a presença de grande parte das unidades de proteção ambiental localizadas em área de caráter urbano na RMSP. Baseado em tal conhecimento se sugeriu setores desde os mais vulneráveis à conservação do cinturão verde, aqueles constituídos de unidades de proteção ambiental dadas em área de caráter urbano, aos com vulnerabilidade menor, de unidades de proteção ambiental dadas em área de caráter natural. Foram sugeridos também os mais adequados e em que se prognostica a intensa expansão urbana e aqueles em que podem ser estabelecidos parques urbanos metropolitanos, ambos cumprem o papel de atender as necessidades da metrópole e amenizar a ocupação dos setores que devem ter conservação prioritária. Concluiu-se que na RMSP a organização espacial vislumbrada só não é válida para os trechos de escarpa das Serras do Mar e de Paranapiacaba e que a realidade pode ser abordada sob o ponto de vista da área das formas espaciais, sendo que a partir desse tipo de análise é possível sugerir setores espaciais que visem contribuir ao planejamento de determinados territórios, seja sob o foco ambiental ou social.
The goal of this research was to investigate the relationship between the urbanization and the sedimentary and crystalline lands in the Metropolitan Region of São Paulo (MRSP). In order to achieve this, two types of areas were identified: an area with urban character, and areas with natural character. The first is the one which contains all or most of a specific spatial shape, the metropolitan area, occurring in the majority of the sedimentary and associated crystalline lands (with widespread planning). The latter are characterized by the predominance of the greenbelt, which surrounds the metropolitan area, occurring on the crystalline lands not associated to the sedimentary ones. The greenbelt areas neither have widespread planning, nor contain sedimentary lands that could facilitate their urbanization. Another goal was to demonstrate that such organization is reproduced through actions of spatial character, which are here understood as the establishment and proposition of spatial units over time. Once such organization was identified and demonstrated, it was used as a base to propose the division of the MRSP in sectors with different priorities for the greenbelt conservation. In order to do so, the Regional Method of Richard Hartshorne (1978), that proposes a relationship between the Idiographic and Nomothetic Geography, was articulated. This approach involved the utilization of spatial samples located in the City of São Paulo, well representative of all the transition and differentiation between environments associated to the metropolitan area and to the greenbelt. In every sample, specific spatial integrations were performed, and from their comparison it was identified a parameter associated to the occurrence of the metropolitan area. This parameter was associated to the delimitation and configuration of the intended spatial organization. The elevation of 800 meters corresponded to this parameter, thus, the lowlands with regional significance were associated to the urban area, and the higher ones to the natural areas. It was demonstrated that actions of spatial nature, the east-west axis of urban expansion induced by the government since the 1970s, as well as the environmental protection units of several categories of conservation located in the MRSP, reproduce such spatial organization, and corroborate it. It was also possible to identify actions which agreed with this spatial organization and might be justified in the societys logic, and not only in the scientific or environmental logic. Such analysis allowed the identification of a complementary spatial organization that associates the urban expansion to climatic types and socially justifies the presence of a great part of the environmental protection units located in the urban area in MRSP. Based in such knowledge, it were suggested sectors ranging from the most vulnerable ones for the greenbelt conservation, which are constituted of environmental protection units situated in the area with urban character, to the less vulnerable ones, with environmental protection units situated in the areas with natural character. It was also suggested the most suitable sectors in which it is prognosticated the intense urban expansion, and those in which metropolitan parks can be established. Both of them fulfill the role of answering the needs of the metropolis and mitigate the occupation of sectors that must have priority conservation. It was concluded that in MRSP the spatial organization glimpsed is not valid only for the escarpment areas of Serra do Mar and Paranapiacaba, and that the reality can be approached from the point of view of the area of the spatial shapes. From this type of analysis its possible to suggest spatial sectors that aim to contribute to the territorial planning,under the environmental or social focus.

Abstract:
The project has been concerned with the study of radon and other natural radionuclides in the U-238 decay series in the environment. The contribution made by radon and its daughter radionuclides to population radiation dose both in the air and in water supplies has been investigated. The natural radioactivity of the river water, stream water, sediments and freshwater mussels have been measured using a thick source alpha counting technique and γ-spectrometry (water samples were preconcentrated by manganese dioxide precipitation method). The ^226Ra activity ranged from 10-20 Bq m^-3 in the river and 4-30 Bq m^-3 in stream water. The highest values were found close to the source of the river where the water flowed through an area of igneous rocks. Such granite type rocks are enriched in uranium and thorium. Concentrations of radon and its daughters were measured, indoors and outdoors, using a grab sample technique. Outdoor concentrations were 10-30 Bq m^-3 depending on underlying rocks, meteorological condition (pressure, temperature, snow, rain), while indoor values ranged between 20 and 600 Bq m^-3 depending on radon input rate (source strength, ventilation rate and pressure inside the building). The relationship between the indoor ^222Rn concentration and ventilation rate was investigated. The radiation dose and the consequent risk due to inhalation of radon and its daughters were estimated. The annual effective dose equivalent ranged from 0.12 to 11 mSv. The radon concentrations in well waters were measured and were found to range between 3 and 76 Bq ℓ-1. This variation can be associated with different bedrock. A model predicting average indoor increments due to this source is presented and supported by a series of measurements made in the houses which were supplied by well water. The maximum annual effective dose equivalent from inhalation and ingestion was found to be 0.27 and 0.054 mSv respectively.

CAPES
Em razão da importância que possui o setor mineral para a economia brasileira, especificamente para os municípios que são mineradores, esta dissertação buscou examinar como são destinadas as receitas geradas sob a forma de royalty mineral, chamado de Compensação Financeira pela Exploração de Recursos Minerais (CFEM). Dois são os objetivos: i) verificar se a CFEM tem impacto sobre o Índice FIRJAM de Desenvolvimento Municipal (IFDM), um índice calculado pela Federação das Indústrias do Rio de Janeiro (FIRJAM) para todo o país; ii) identificar a relação existente entre a CFEM e as despesas de capital municipal. Para atingir o primeiro objetivo, foi estimado um painel estático utilizando todos os municípios brasileiros no período de 2005-2010, inserindo uma dummy de grandes beneficiários, para verificar se as receitas são aplicadas em prol da comunidade local, o que pode ser verificado por um impacto positivo sobre o IFDM; também foram inseridas dummies de região, para investigar se há um efeito diferente sobre cada região brasileira e controlar a heterogeneidade existente entre os municípios. Em relação ao segundo objetivo, estimou-se um painel dinâmico utilizando uma amostra contendo apenas os municípios que receberam a sua cota-parte da CFEM no período de 2004-2011. Os resultados encontrados indicam que a CFEM não possui nenhum efeito sobre o IFDM dos grandes beneficiários. Já os impactos sentidos nas diferentes regiões foram negativos, com exceção da região Nordeste, que mostrou uma relação direta e positiva entre a CFEM e o IFDM. Os resultados da estimação do painel dinâmico também mostram uma relação direta e significativa entre os royalties minerais e os gastos de investimento, ainda que o coeficiente tenha sido pequeno. Portanto, segundo esses resultados, a existência de uma maldição ou benção dos recursos minerais nos municípios brasileiros é ambígua: a evidência é a favor de uma maldição para a maior parte das regiões brasileiras, considerando os resultados sobre o IFDM; contudo, os gastos de investimento sugerem que há uma benção para os municípios mineradores, o que é compatível com uma possível utilização da regra de Hartwick.
Given the importance that the mineral sector has on the Brazilian economy, more specifically on the municipalities that are miners, this dissertation sought to examine how are being designed the revenues generated by minerals in the form of mineral royalty, the CFEM. Two were the secondary objects: i) check whether the CFEM would impact positively the IFDM and; ii) identify the relationship between CFEM and municipal capital expenditures. To achieve the first objective, a static panel was estimated using all Brazilian municipalities in the period of 2005 to 2010, by inserting a dummy of large beneficiaries to verify that they are reversing these revenues on behalf of the local community and should therefore being positively impact the IFDM; likewise dummies of region were inserted to investigate the effects felt by each region, being also a way to control the heterogeneity among municipalities. As for the second objective, a dynamic panel was estimated using a sample containing only the municipalities that received their quota-share of the CFEM in the period of 2004 to 2011. The results indicated that the CFEM has no impact on IFDM major beneficiaries; as for the regions, the impact felt in different region were, as a rule, negative; the exception is in the Northeast region, which showed a direct relationship between the IFDM and the CFEM. The estimated results of the dynamic panel also showed a significant direct relationship between the mineral royalties and investment spending, although the coefficient was small. Therefore, the existence of a curse or a blessing of mineral resources in Brazilian municipalities is ambiguous; it presents itself as a curse to most Brazilian regions, considering the IFDM, however it is a blessing for mining cities considering public investments spending, suggesting a possible use of Hartwick’s rule.

Mestrado em Planeamento Regional e Urbano
O presente estudo originou uma investigação sobre o desenvolvimento local em Áreas Protegidas, focalizando o espaço rural em que o Parque Natural de Montesinho foi criado. Uma revisão bibliográfica possibilitou uma maior compreensão do contexto internacional e nacional da criação de Áreas Protegidas, permitindo igualmente o entendimento destas num contexto de desenvolvimento local e rural, dos benefícios e conflitos que podem surgir desta simbiose. Reportando para o caso de estudo, o Parque Natural de Montesinho, para além de toda a caracterização legal, geográfica e socioeconómica, analisamos a estratégia de gestão, através do seu regulamento e a percepção de alguns actores locais (obtida em entrevistas) sobre o impacte do parque para o desenvolvimento deste território. Tendo por base toda esta caracterização e análise empírica, surgiram um conjunto de questões, cuja reflexão levou-nos em busca de outras fontes de informação e a um olhar mais profundo e crítico ao território que tem tanto de natural como de antrópico. Sem nunca esquecer que o objectivo de protecção da natureza só é possível com o envolvimento das populações locais.
The present study led to an investigation about local development in protected areas, focusing on rural areas, where the Montesinho Natural Park was created. A literature review has enabled a greater understanding of national and international context of the creation of protected areas, allowing also the understanding of these in the context of local and rural development, benefits and conflicts that may arise from this symbiosis. Referring to the case study, the Montesinho Natural Park, in addition to the legal, geographic and socio-economic characterization, we analyse the management strategy, though its rules and the perception of some local actors (obtained in interviews) on the impact of the park for the development of this territory. Based on all this characterization and empirical analysis, came out a number of questions, whose thinking has led us to seek other sources of information and a look deeper and critical to the territory, that is as natural as anthropogenic. Never forgetting that the purpose of protection of nature is only possible with the involvement of the local people.
