During the last two decades there have been but a handful of recorded cases of electoral fraud in Latin America. However, survey research consistently shows that often citizens do not trust the integrity of the electoral process. This dissertation addresses the puzzle by explaining the mismatch between how elections are conducted and how the process is perceived. My theoretical contribution provides a double-folded argument. First, voters’ trust in their community members (“the local experience”) impacts their level of confidence in the electoral process. Since voters often find their peers working at polling stations, negative opinions about them translate into negative opinions about the election. Second, perceptions of unfairness of the system (“the global effect”) negatively impact the way people perceive the transparency of the electoral process. When the political system fails to account for social injustice, citizens lose faith in the mechanism designed to elect representatives -and ultimately a set of policies. The fact that certain groups are systematically disregarded by the system triggers the notion that the electoral process is flawed. This is motivated by either egotropic or sociotropic considerations. To test these hypotheses, I employ a survey conducted in Costa Rica, El Salvador, Honduras, and Guatemala during May/June 2014, which includes a population-based experiment. I show that Voters who trust their peers consistently have higher confidence in the electoral process. Whereas respondents who were primed about social unfairness (treatment) expressed less confidence in the quality of the election. Finally, I find that the local experience is predominant over the global effect. The treatment has a statistically significant effect only for respondents who trust their community. Attribution of responsibility for voters who are skeptics of their peers is clear and simple, leaving no room for a more diffuse mechanism, the unfairness of the political system. Finally, now I extend analysis to the Latin America region. Using data from LAPOP that comprises four waves of surveys in 22 countries, I confirm the influence of the “local experience” and the “global effect” as determinants of the level of confidence in the electoral process.

A Escola Comunitária de S. Miguel de Machede é uma Escola! A afirmação parece uma redundância mas não é. Na realidade, desde Março de 1998 que na vila de S. Miguel de Machede (concelho de Évora), no seio de uma associação de desenvolvimento comunitário chamada SUÃO, existe uma preocupação fundamental: preservar e valorizar o património mais valioso e cada vez mais reduzido do Alentejo rural: as pessoas. Como é que se preserva e valoriza o património humano senão através da Educação? A Escola Comunitária de S. Miguel de Machede assenta num modelo de desenvolvimento curricular baseado no modelo PADéCA – Programa de Auxílio ao Desenvolvimento da Capacidade de Aprender e tem vindo a promover atividades educativas nas mais diversas áreas. Um dos seus projetos mais emblemáticos será talvez a Biblioteca Comunitária, através da qual, praticamente todas as cerca de 250 famílias de S. Miguel de Machede recebem, diária, gratuita e domiciliarmente um jornal diário, há mais de um ano, consecutivamente. No entanto, outras atividades têm preenchido os dias e as noites de muitos habitantes da nossa vila. Com o Grupo de Teatro, o Cante Alentejano e no meio das exposições do Museu Comunitário, vai-se fazendo o Jornal Comunitário. Nos intervalos de tudo isto assegura-se o funcionamento do Gabinete da Papelada. Porquê tudo isto? Fundamentalmente, para sermos felizes na nossa terra e para aprendermos. Aprendermos a viver uns com os outros; aprendermos coisas de outras terras e de outras gentes; aprendermos a aprender ao longo da nossa vida. Porque não há coisa que nos dê mais Felicidade que aprendermos com os nossos amigos e família coisas que nos dão prazer à vida.

En El Salvador a lo largo de los últimos diez años, se han tratado de implementar diversas medidas de política económica, las cuales pretenden apalear los principales problemas que aquejan al país; sin embargo es notorio observar que estas medidas no han sido suficientes para solucionarlos. Desde los años 90´s el crecimiento económico presentaba comportamientos oscilantes y en promedio muy bajos en comparación a otros países, ya que en ninguno de los últimos quince años, se ha logrado crecer a tasas per cápita superiores al 3%, lo cual es deficiente en comparación con el resto del mundo, en promedio el PIB per cápita promedio mundial es de (1.96%) y El Salvador tiene un promedio de crecimiento de apenas un (0.93%), otro aspecto importante de mencionar es la enorme brecha que existe en los niveles de ingresos, lo que muestra una alta desigualdad y puede observarse al comparar los índices de desarrollo humano de El Salvador con el resto del mundo, posicionándonos en el lugar N°103 en promedio, lo que nos lleva a pensar que hace falta mejorar el nivel de desarrollo en el país. Como un intento por apostarle al crecimiento económico, se diseña una estrategia enfocada a promover de forma sostenible el Desarrollo Económico Local, referida a un proceso de concertación de diversos actores, como los gobiernos locales, la sociedad civil organizada y el sector privado, con el propósito de mejorar la calidad de vida de la población, mediante la creación de más empleos y la dinamización de la economía de un territorio definido. Se trata de un proceso ampliamente participativo de todos los sectores, que promueve alianzas público-privadas en un territorio con el fin de estimular la actividad económica local. Exige el diseño de una visión en común y la implementación permanente de una estrategia de desarrollo, utilizando los recursos locales (desarrollo endógeno) y el desarrollo de ventajas competitivas en un contexto global. Además requiere crear y fortalecer la institucionalidad local de gestión, fortalecer las competencias en la población, la creación de un ambiente favorable de negocios para la atracción de inversiones y la creación de nuevas empresas, promoción de la competitividad de las empresas y la generación de ventaja competitiva regional. Es decir, se necesita la construcción de una visión y estrategia común del desarrollo territorial. Esta investigación se centró en la evaluación de la estrategia Un Pueblo Un Producto, como una técnica enfocada a promover y generar desarrollo económico local, a través de la promoción de las pequeñas y medianas empresas en mejorar la calidad de vida de los habitantes de las localidades propiciando el desarrollo de las capacidades que posibiliten dar mayor valor agregado a sus recursos, con el fin de promover su identidad, el respeto por la cultura local, el sentido de pertenencia y el sentimiento de orgullo. Este Movimiento al estar desarrollándose en más de 30 países, ha motivado la creación de una base de integración internacional, a través de la puesta de sus productos en los respectivos mercados; locales, regionales, nacionales e incluso internacionales, posibilitando de esta manera diversificar la oferta exportable, así como una amplia red de intercambio de información. Con la ayuda directa de CONAMYPE, institución encargada de la puesta en marcha y coordinación de la estrategia, se pudo iniciar la investigación, facilitando el acceso a la información y el cercamiento con los líderes en los diversos municipios en estudio. Se hizo un muestreo de selección al azar y avalado por CONAMYPE de tres municipios con diferentes rubros y actividades económicas; San Lorenzo con la producción de Jocote barón rojo, El Congo como un atractivo turístico y Concepción Quezaltepeque con la producción de hamacas. Con el objetivo de realizar una evaluación precisa de la estrategia se utilizaron varias herramientas estadísticas para la recolección de la información, las encuestas fueron pasadas a los habitantes de los municipios para conocer el impacto que ha tenido la estrategia en la localidad, y las entrevistas a los principales actores involucrados como el director de CONAMYPE, alcaldes, principales productores y empresarios, representantes de la estrategia en los municipios, entre otros. También se creó un índice de resultados obtenidos para analizar el comportamiento directo de la estrategia en cuatro pilares fundamentales, los cuales son: Dimensión humana, social, económica y ambiental. Los resultados de los índices calculados para las cuatro dimensiones, han permitido observar las fortalezas de la estrategia aunque aún hay deficiencias en el progreso económico del desarrollo económico local y pese a los esfuerzos que se han hecho por tratar de mejorar las condiciones de vida de los habitantes de los municipios, aún hay varios aspectos que deben mejorarse, no obstante lo anterior la implementación de la Estrategia UPUP ha mejorado el desarrollo económico local en los tres municipios que se realizó la investigación.

Overrecentdecades,remotesensinghasemergedasaneffectivetoolforimprov- ing agriculture productivity. In particular, many works have dealt with the problem of identifying characteristics or phenomena of crops and orchards on different scales using remote sensed images. Since the natural processes are scale dependent and most of them are hierarchically structured, the determination of optimal study scales is mandatory in understanding these processes and their interactions. The concept of multi-scale/multi- resolution inherent to OBIA methodologies allows the scale problem to be dealt with. But for that multi-scale and hierarchical segmentation algorithms are required. The question that remains unsolved is to determine the suitable scale segmentation that allows different objects and phenomena to be characterized in a single image. In this work, an adaptation of the Simple Linear Iterative Clustering (SLIC) algorithm to perform a multi-scale hierarchi- cal segmentation of satellite images is proposed. The selection of the optimal multi-scale segmentation for different regions of the image is carried out by evaluating the intra- variability and inter-heterogeneity of the regions obtained on each scale with respect to the parent-regions defined by the coarsest scale. To achieve this goal, an objective function, that combines weighted variance and the global Moran index, has been used. Two different kinds of experiment have been carried out, generating the number of regions on each scale through linear and dyadic approaches. This methodology has allowed, on the one hand, the detection of objects on different scales and, on the other hand, to represent them all in a sin- gle image. Altogether, the procedure provides the user with a better comprehension of the land cover, the objects on it and the phenomena occurring.

This thesis studies mobile robotic manipulators, where one or more robot manipulator arms are integrated with a mobile robotic base. The base could be a wheeled or tracked vehicle, or it might be a multi-limbed locomotor. As robots are increasingly deployed in complex and unstructured environments, the need for mobile manipulation increases. Mobile robotic assistants have the potential to revolutionize human lives in a large variety of settings including home, industrial and outdoor environments.

Mobile Manipulation is the use or study of such mobile robots as they interact with physical objects in their environment. As compared to fixed base manipulators, mobile manipulators can take advantage of the base mechanism’s added degrees of freedom in the task planning and execution process. But their use also poses new problems in the analysis and control of base system stability, and the planning of coordinated base and arm motions. For mobile manipulators to be successfully and efficiently used, a thorough understanding of their kinematics, stability, and capabilities is required. Moreover, because mobile manipulators typically possess a large number of actuators, new and efficient methods to coordinate their large numbers of degrees of freedom are needed to make them practically deployable. This thesis develops new kinematic and stability analyses of mobile manipulation, and new algorithms to efficiently plan their motions.

I first develop detailed and novel descriptions of the kinematics governing the operation of multi- limbed legged robots working in the presence of gravity, and whose limbs may also be simultaneously used for manipulation. The fundamental stance constraint that arises from simple assumptions about friction and the ground contact and feasible motions is derived. Thereafter, a local relationship between joint motions and motions of the robot abdomen and reaching limbs is developed. Baseeon these relationships, one can define and analyze local kinematic qualities including limberness, wrench resistance and local dexterity. While previous researchers have noted the similarity between multi- fingered grasping and quasi-static manipulation, this thesis makes explicit connections between these two problems.

The kinematic expressions form the basis for a local motion planning problem that that determines the joint motions to achieve several simultaneous objectives while maintaining stance stability in the presence of gravity. This problem is translated into a convex quadratic program entitled the balanced priority solution, whose existence and uniqueness properties are developed. This problem is related in spirit to the classical redundancy resoxlution and task-priority approaches. With some simple modifications, this local planning and optimization problem can be extended to handle a large variety of goals and constraints that arise in mobile-manipulation. This local planning problem applies readily to other mobile bases including wheeled and articulated bases. This thesis describes the use of the local planning techniques to generate global plans, as well as for use within a feedback loop. The work in this thesis is motivated in part by many practical tasks involving the Surrogate and RoboSimian robots at NASA/JPL, and a large number of examples involving the two robots, both real and simulated, are provided.

Finally, this thesis provides an analysis of simultaneous force and motion control for multi- limbed legged robots. Starting with a classical linear stiffness relationship, an analysis of this problem for multiple point contacts is described. The local velocity planning problem is extended to include generation of forces, as well as to maintain stability using force-feedback. This thesis also provides a concise, novel definition of static stability, and proves some conditions under which it is satisfied.

My dissertation is the first project on the Haitian Platform for Advocacy for an Alternative Development- PAPDA, a nation-building coalition founded by activists from varying sectors to coordinate one comprehensive nationalist movement against what they are calling an Occupation. My work not only provides information on this under-theorized popular movement but also situates it within the broader literature on the postcolonial nation-state as well as Latin American and Caribbean social movements. The dissertation analyzes the contentious relationship between local and global discourses and practices of citizenship. Furthermore, the research draws on transnational feminist theory to underline the scattered hegemonies that intersect to produce varied spaces and practices of sovereignty within the Haitian postcolonial nation-state. The dissertation highlights how race and class, gender and sexuality, education and language, and religion have been imagined and co-constituted by Haitian social movements in constructing ‘new’ collective identities that collapse the private and the public, the rural and the urban, the traditional and the modern. My project complements the scholarship on social movements and the postcolonial nation-state and pushes it forward by emphasizing its spatial dimensions. Moreover, the dissertation de-centers the state to underline the movement of capital, goods, resources, and populations that shape the postcolonial experience. I re-define the postcolonial nation-state as a network of local, regional, international, and transnational arrangements between different political agents, including social movement actors. To conduct this interdisciplinary research project, I employed ethnographic methods, discourse and textual analysis, as well as basic mapping and statistical descriptions in order to present a historically-rooted interpretation of individual and organizational negotiations for community-based autonomy and regional development. ^

An important episode of carbon sequestration, Oceanic Anoxic Event 1a (OAE-1a), characterizes the Lower Aptian worldwide, and is mostly known from deeper-water settings. The present work of two Lower Aptian deposits, Madotz (N Spain) and Curití Quarry (Colombia), is a multiproxy study that includes fossil assemblages, microfacies, X-ray diffraction bulk and clay mineralogy, elemental analyses (major, minor, trace elements), Rock-Eval pyrolysis, biomarkers, inorganic and organic carbon content, and stable carbon isotopes. The results provide baseline evidence of the local and global controlling environmental factors influencing OAE-1a in shallow-water settings. The data also improve our general understanding of the conditions under which organic-carbon-rich deposits accumulate. The sequence at Madotz includes four intervals (Unit 1; Subunits 2a, 2b and 2c) that overlap the times prior to, during and after the occurrence of OAE-1a. The Lower Unit 1(3m thick) is essentially siliciclastic, and Subunit 2a (20m) contains Urgonian carbonate facies that document abruptly changing platform conditions prior to OAE-1a. Subunit 2b (24.4 m) is a mixed carbonate-siliciclastic facies with orbitolinid-rich levels that coincides with OAE-1a δ13C stages C4-C6, and is coeval with the upper part of the Deshayesites forbesi ammonite zone. Levels with pyrite and the highest TOC values (0.4-0.97%), interpreted as accumulating under suboxic conditions, and are restricted to δ13C stages C4 and C5. The best development of the suboxic facies is at the level representing the peak of the transgression. Subunit 2c, within δ13C stage C7, shows a return of the Urgonian facies. The 23.35-m section at Curití includes a 6.3-m interval at the base of the Paja Formation dominated by organic-rich marlstones and shales lacking benthic fossils and bioturbation, with TOC values as high as 8.84%. The interval overlies a level containing reworked and phosphatized assemblages of middle Barremian to lowest Aptian ammonites. The range of values and the overall pattern of the δ13Corg (-22.05‰ to -20.47‰) in the 6.3m-interval is comparable with Lower Aptian δ13C stage C7. Thus, conditions of oxygen depletion at this site also occurred after Oceanic Anoxic Event-1a, which developed between carbon isotope stages C3 and C6. Both sites, Madotz and Curití, attest to the importance of terrigenous and nutrient fluxes in increasing OM productivity that led to episodic oxygen deficiency.

Portugal’s manufacturing sector has a significant importance both in national income and employment. As has been pointed out by several researchers, the traditional methods of analysis fail to grasp all the dimensions of economic competitiveness. This dissertation is then, at its core, an analysis of Portugal’s manufacturing industry in terms of the latter’s value added to production and impact to employment under the framework of global value chains. The current dissertation seeks to study in which way the Portuguese manufacturing industry, and its respective sectors, has a direct and indirect impact on the creation of value added and employment and how this impact can be measured. For development of this work the input-output approach for calculation of multipliers and the new framework proposed by Timmer et al. (2013) for calculation of GVC income and GVC jobs indicators were used, elaborated on the basis of the WIOD project dataset. Moreover, to illustrate the application of the provided methodology the Portuguese textile industry was used as an example. It was found that the changes in final demand of such sectors as Pulp, Paper, Printing and Publishing; Machinery, Nec and Textiles and Textile Products would have a larger impact on generated value added than other manufacturing sectors. At the same time, employment created by the changes in final demand would be more impacted by such sectors as Food, Beverages and Tobacco; Wood and Products of Wood and Cork and Textiles and Textile Products. In this regard, the number of low-skilled workers in Portugal seems to be more effected by changes in final demand, than those occupied by higher -skilled individuals. Moreover, it was found that the distribution of GVC income and GVC jobs for the Portuguese manufacturing industry shares a similar outlook. However, upon closer inspection of GVC labour distribution by skill levels there seems to exist a general progression in which low-skilled jobs requirements are met by local resources, while the need for higher skilled jobs require a greater “off-shoring” of work The results obtained through calculations of presented multipliers provide a powerful tool for policy makers in strategic planning of development of national economy. Using the provided methodology and obtained results, a government and supranational organizations could define which industry would have the greatest impact for an additional unit of output generated through the economy, and thus define the sectors for further investments.

In a globalized economy, the use of natural resources is determined by the demand of modern production and consumption systems, and by infrastructure development. Sustainable natural resource use will require good governance and management based on sound scientific information, data and indicators. There is a rich literature on natural resource management, yet the national and global scale and macro-economic policy making has been underrepresented. We provide an overview of the scholarly literature on multi-scale governance of natural resources, focusing on the information required by relevant actors from local to global scale. Global natural resource use is largely determined by national, regional, and local policies. We observe that in recent decades, the development of public policies of natural resource use has been fostered by an “inspiration cycle” between the research, policy and statistics community, fostering social learning. Effective natural resource policies require adequate monitoring tools, in particular indicators for the use of materials, energy, land, and water as well as waste and GHG emissions of national economies. We summarize the state-of-the-art of the application of accounting methods and data sources for national material flow accounts and indicators, including territorial and product-life-cycle based approaches. We show how accounts on natural resource use can inform the Sustainable Development Goals (SDGs) and argue that information on natural resource use, and in particular footprint indicators, will be indispensable for a consistent implementation of the SDGs. We recognize that improving the knowledge base for global natural resource use will require further institutional development including at national and international levels, for which we outline options.

Goncalo de Melo Bandeira Counter-Terrorism, State of Emergency and Human Rights. In the global cities, the fight against terrorism is a way forward. Prevention of terrorism is another possible way. There are legal systems where the prevailing idea is combating terrorism. Fight, because is possible: life imprisonment or informal death penalty or even torture. While other jurisdictions only follow the prevention of terrorist crime: the retribution and positive general prevention and the resocialization. There may be extreme cases also in restorative justice. The recent terrorist attacks in Paris on 11.13.2015 have shown to the different types of police several problems. Some of those are: the declaration of State of emergency and the consequent restriction of human rights as the privacy of human communication or the liberty of travel by local city citizens or foreign citizens or the public entertainment shows, the problem of money laundering and the restriction of the business as usual, the vicious circle of more isolation from some urban communities, v.g. muslims, and other citizens also; and, brevitatis causa, the criminological problem of the causes and consequences of terrorism.

Abstract : OBJECTIVES : Canadian medical (MD), physiotherapy (PT) and occupational therapy (OT) students increasingly show an interest in global health experiences (GHEs). As certain moral hazards can occur as a result of student GHEs, a growing consensus exists that universities must have an established selection process, in-depth pre-departure training (PDT), adequate onsite supervision and formal debriefing for their students. This study aimed at identifying current practices in Canadian MD, PT and OT programs and discussing areas for improvement by comparing them with recommendations found in the literature. METHODS : Canadian MD, PT and OT programs (n = 45) were invited to answer an online survey about their current practices for GHE support and training. The survey included 24 close-ended questions and 18 open-ended questions. Descriptive statistics and a thematic analysis were performed on the data and results were discussed with recommendations found in the literature. RESULTS : Twenty-three programs responded to the survey. Student selection processes varied across universities; examples included using academic performance, interviews and motivation letters. All but 1 MD program had mandatory PDT; content and teaching formats varied, as did training duration (2-38 hours). All but 1 MD program had onsite supervision; local clinicians were frequently involved. Debriefing, although not systematic, covered similar content; debriefing was variable in duration (1-8 hours). CONCLUSIONS : Many current practices are encouraging but areas for improvement exist. Integrating global health content into the regular curriculum with advanced study option in global health for students participating in GHEs could help universities standardize support and training.
