Two key solutions to reduce the greenhouse gas emissions and increase the overall energy efficiency are to maximize the utilization of renewable energy resources (RERs) to generate energy for load consumption and to shift to low or zero emission plug-in electric vehicles (PEVs) for transportation. The present U.S. aging and overburdened power grid infrastructure is under a tremendous pressure to handle the issues involved in penetration of RERS and PEVs. The future power grid should be designed with for the effective utilization of distributed RERs and distributed generations to intelligently respond to varying customer demand including PEVs with high level of security, stability and reliability. This dissertation develops and verifies such a hybrid AC-DC power system. The system will operate in a distributed manner incorporating multiple components in both AC and DC styles and work in both grid-connected and islanding modes. ^ The verification was performed on a laboratory-based hybrid AC-DC power system testbed as hardware/software platform. In this system, RERs emulators together with their maximum power point tracking technology and power electronics converters were designed to test different energy harvesting algorithms. The Energy storage devices including lithium-ion batteries and ultra-capacitors were used to optimize the performance of the hybrid power system. A lithium-ion battery smart energy management system with thermal and state of charge self-balancing was proposed to protect the energy storage system. A grid connected DC PEVs parking garage emulator, with five lithium-ion batteries was also designed with the smart charging functions that can emulate the future vehicle-to-grid (V2G), vehicle-to-vehicle (V2V) and vehicle-to-house (V2H) services. This includes grid voltage and frequency regulations, spinning reserves, micro grid islanding detection and energy resource support. ^ The results show successful integration of the developed techniques for control and energy management of future hybrid AC-DC power systems with high penetration of RERs and PEVs.^

Systems security is essential for the efficient operation of all organizations. Indeed, most large firms employ a designated ‘Chief Information Security Officer’ to coordinate the operational aspects of the organization’s information security. Part of this role is in planning investment responses to information security threats against the firm’s corporate network infrastructure. To this end, we develop and estimate a vector equation system of threats to 10 important IP services, using industry standard SANS data on threats to various components of a firm’s information system over the period January 2003 – February 2011. Our results reveal strong evidence of contagion between such attacks, with attacks on ssh and Secure Web Server indicating increased attack activity on other ports. Security managers who ignore such contagious inter-relationships may underestimate the underlying risk to their systems’ defence of security attributes, such as sensitivity and criticality, and thus delay appropriate information security investments.

La vulnérabilité est l’attribut fondamental justifiant le passage des frontières du refuge canadien (Rousseau et al., 2002 ; Clément et Bolduc, 2004). Elle est preuve d’insécurité pour la victime requérant l’asile ; elle est aussi porteuse d’espérance de sécurité en terre hospitalière. Elle est pourtant potentiel réactualisé dans l’insécurité d’un statut incertain en terre d’accueil (Agamben, 1997 ; D’Halluin, 2004). Violente immersion. En attendant que les preuves de sa vulnérabilité originelle soient validées, le demandeur d’asile se retrouve dans un entre-deux a-territorial et atemporel (Agier, 2002 ; Le Blanc, 2010) et dans une précarité tout aussi dangereuse (Ouimet et al., 2009). Des besoins émergent en cette terre inconnue, or l’accès aux soins de santé lui est limité par des textes de lois ambigus et leurs interprétations maladroites (Harris et Zuberi, 2015). Ainsi lorsqu’il se heurte à des barrières érigées par une transmission d’informations défectueuse, sa précarité ne fait qu’empirer. Tel un boomerang, ce paradoxe cultive leur vulnérabilité. Alors que les recherches interrogent les divers intervenants en santé (Asgary et Smith, 2013), j’ai choisi de donner la parole aux premiers concernés et de relayer leur vécu par rapport à leur propre personne. Deux objectifs principaux guident la recherche : documenter dans un premier temps leur parcours de quête de soins à partir de la circulation des informations formelles et informelles dans le but de sonder leur avis sur la vulnérabilité qui leur est attribuée ; documenter dans un second temps leur parcours migratoire de quête de soi afin de mettre en lumière les stratégies alternatives d’entrée en contact avec la société d’accueil pour négocier voire rejeter cette identité vulnérable. J’ai rencontré pour cela des demandeurs d’asile lors d’un terrain de huit mois au sein d’un organisme communautaire d’hébergement à Montréal. Dans ce contexte d’accompagnement et de stabilité spatiale, accalmie bienvenue au terme d’un itinéraire semé d’embûches, les ressources informationnelles sont à leur disposition et la reconnaissance sociale est à l’honneur. En parallèle, beaucoup témoignent de la diminution de leurs besoins de soins de santé. En cette communauté thérapeutique (Pocreau, 2005), véritable tremplin vers la société d’accueil en attendant un statut reconnu, ils bénéficient d’une possibilité de participation sociale et d’un sentiment d’appartenance valorisant. Si des conditions précaires peuvent aggraver la vulnérabilité, le bricolage de conditions positives favorise la résilience (Cleveland et al., 2014), créant un environnement revitalisant qui leur permet de rebondir.

This doctoral Thesis aims to approach the philosophical significance of the Italian author Elsa Morante, expressed through poetic narrative of her second great novel L'isola di Arturo (1957). For this reason, the inductive knowledge has been opted, which can be reached through the symbolic study of the sea and the mediterranean. From the philosophical and psychoanalytical research from such authors as Mircea Eliade, Gaston Bachelard and Carl Jung, linked to the circle of the Eranos Foundation in Switzerland, where the most rigorous multidisciplinary science theories of nature and man converged, and the Grenoble imaginary Center of Research, driven by anthropologist Gilbert Durand in 1966, a revealing investigation of aquatic and marine image has been carried out. In this context of convergence, the work Las estructuras antropológicas del imaginario by Durand, has fulfilled the important catalytic role, of both the Renaissance conception that wants to observe certain universal components in the symbolic vision that nourishes literary expression, as well as the compilation of large images that illuminate the human imaginary of all time. Objectives and results In this regard, it has been considered that the appropriate approach to morantiano imaginary, could only be done thoroughly, based on a repertoire of images as complete as possible, which, if performed from the anthropological compendium of people and civilization of the world, it is offered as a study backed by profound consistency which is the basis of the method. Therefore, it is said, the imaginary is studied and understood through itself. Thus, the internal coherence of this method is seen to be configured as a form of knowledge of human thought because research, from the symbolic point of view, dissects reality in various ways, however, the most seductive is to consider the possibility of an internal coherence between them to converge at a common conclusion which includes all of them. This fact determines the systematization which is shown in the first part of this thesis, as the image and symbol have a close homogeneity between the signifier and the meaning, so that metaphorical expression is established as the structuring element of the human imaginary and the literary representation...

Alfonso V of Aragon (1396-1458), who won from his contemporaries the title “the Magnanimous”, became one of the most brilliant fifteenth century monarchs, not only because of being a shrewd politician and king of one of the main kingdoms in the Iberian Peninsula, but also due to his cultural activity. Thanks to him the Aragonese territories were extended throughout the Mediterranean up to Naples, where he established a magnificent court that turned into maybe the most remarkable centre of intellectual vitality and development of Humanism. His patronage attracted a considerable number of leading poets of the period, as well as the most important Italian humanists. The presence of so many writers and outstanding scholars, together with the academic environment that the monarch encouraged, promoted an enormous literary production in four languages: Latin, Spanish, Catalan and Italian. Additionally, the valuable library gathered by the king and the Academy founded in order to spread knowledge illustrate part of his intellectual concerns. This way, through his love to literature and generosity to men of letters, Alfonso the Magnanimous boosted the culture of that time. The principal protagonist in the cultural activities of the circle of erudites formed around the sovereign was Antonio Beccadelli, called Panormita (1394-1471). He, one of the most prominent personalities of Italian Humanism, assumed the role of main royal advisor. His work De dictis et factis Alphonsi regis (The sayings and deeds of king Alfonso), which will be studied in our dissertation, became a very popular text about Alfonso’s personality, as a kind of biography based on anecdotes of the Magnanimous’ life by way of exempla to be imitated. The success of these episodes lasted for a long time and they are appreciated even nowadays. The work was valued as specula principum and had great impact in sixteenth century, when De dictis was republished several times and translated from Latin into Spanish. One of these translations, the one by Fortún García de Ercilla, caught our interest since it is in a manuscript signed by Ercilla himself and this version is still unpublished...

Healthcare systems have assimilated information and communication technologies in order to improve the quality of healthcare and patient's experience at reduced costs. The increasing digitalization of people's health information raises however new threats regarding information security and privacy. Accidental or deliberate data breaches of health data may lead to societal pressures, embarrassment and discrimination. Information security and privacy are paramount to achieve high quality healthcare services, and further, to not harm individuals when providing care. With that in mind, we give special attention to the category of Mobile Health (mHealth) systems. That is, the use of mobile devices (e.g., mobile phones, sensors, PDAs) to support medical and public health. Such systems, have been particularly successful in developing countries, taking advantage of the flourishing mobile market and the need to expand the coverage of primary healthcare programs. Many mHealth initiatives, however, fail to address security and privacy issues. This, coupled with the lack of specific legislation for privacy and data protection in these countries, increases the risk of harm to individuals. The overall objective of this thesis is to enhance knowledge regarding the design of security and privacy technologies for mHealth systems. In particular, we deal with mHealth Data Collection Systems (MDCSs), which consists of mobile devices for collecting and reporting health-related data, replacing paper-based approaches for health surveys and surveillance. This thesis consists of publications contributing to mHealth security and privacy in various ways: with a comprehensive literature review about mHealth in Brazil; with the design of a security framework for MDCSs (SecourHealth); with the design of a MDCS (GeoHealth); with the design of Privacy Impact Assessment template for MDCSs; and with the study of ontology-based obfuscation and anonymisation functions for health data.

1-Resumo: A iniciativa privada é um Direito humano fundamental que está consagrado nos ordenamentos jurídicos modernos. No caso português, na Constituição portuguesa. A Declaração Universal dos Direitos Humanos consagra o Direito à propriedade. E, por conseguinte, também a iniciativa privada. A iniciativa privada é tanto mais eficaz na sociedade, quanto mais democrático e livre for o Estado respectivo. A iniciativa privada está ligada ao financiamento público, mas também ao financiamento privado. Seja o financiamento de pessoas singulares, seja o financiamento de pessoas colectivas, organizações. O terrorismo pode ser financiado por outrem, assim como o terrorismo pode financiar actividades lícitas. Por acção ou por omissão. Assim, a isto tudo, está associado o ilícito de branqueamento de capitais. O crime de branqueamento pode ter por origem o crime de terrorismo e/ou o crime de organização terrorista. O branqueamento de capitais também pode servir para financiar o terrorismo. Neste contexto, se desenham zonas de contraste entre Direitos Humanos e Segurança. Entre crime e paz pública. Assim como se geram zonas de confluência entre Segurança e Direitos Humanos. O Direito Humano Fundamental à iniciativa privada e ao financiamento – passivo ou activo – pode sofrer restrições. As restrições podem existir desde que sejam proporcionais, adequadas, necessárias. Ou seja, as restrições têm que respeitar uma intervenção mínima. Assim, em nome da segurança, a prevenção do crime de terrorismo e do crime de branqueamento provoca novas dificuldades também ao próprio sistema económico capitalista. Provoca novas dificuldades ao Direito fundamental da iniciativa privada. Uma vez que o branqueamento de capitais, ou o próprio financiamento, podem estar associados ao crime de terrorismo.§ 1.1-Abstract: The private sector is a fundamental human right that is enshrined in modern legal systems. In the Portuguese case, in the Portuguese Constitution. The Universal Declaration of Human Rights enshrines the right to property. And therefore also the private sector. The private sector is much more effective in society, if the state is more democratic and free. Private initiative is linked to the public funding, but also to private funding. It could be the financing of individual persons, but also the financing of legal persons, organizations. Terrorism can be financed by others, as well as terrorism can finance legal activities. By act or omission. Thus, all this is associated with money laundering. Money laundering may have been originated in the crime of terrorism and / or in the crime of terrorist organization. Money laundering may also be used to finance terrorism. In this context, we have conflict zones between human rights and security. Between crime and public peace. As well as generates confluence zones between security and human rights. The Fundamental Human Right to the private sector and its financing - passive or active - can be restricted. Restrictions would be acceptable if are proportionate, appropriate and necessary. In other words, restrictions must comply with minimum intervention. So in the name of security, the prevention of the crime of terrorism and the Money laundering causes new difficulties also to the capitalist economic system. Causes new problems to the fundamental right of private enterprise. Money laundering or the financing itself may be associated with terrorist crime. The question is also: what could do the criminal lawmaker?

Este estudio de caso se realiza con el objetivo de analizar cómo la cooperación entre Colombia y África occidental en la lucha contra el tráfico de drogas repercute en la imagen del Estado colombiano como referente en esfuerzos antinarcóticos desde la periferia. En consecuencia, se busca conocer la forma en la cual los acuerdos bilaterales interinstitucionales, la participación en foros y la creación de una agenda internacional de lucha contra las drogas para un escenario nacional transformado, configuran la imagen del Estado colombiano. Para tal objetivo, el trabajo se desarrollará a través de los conceptos de identidad de Alexander Wendt, periferia de Mohammed Ayoob y Cooperación Sur-Sur de la Organización de Naciones Unidas y la Agencia Presidencial de Cooperación Internacional de Colombia.

Con el fin de la Segunda Guerra Mundial y el escenario que planteaba la Guerra Fría, la manera de entender y explicar la seguridad en la comunidad internacional se amplió, y pasó de ser concebida únicamente en términos políticos y militares, a incluir aspectos como el medio ambiente, la economía y la sociedad. Por esta razón el concepto de seguridad se complejizó dando paso a la construcción de distintas definiciones y debates alrededor de la ampliación de la agenda de seguridad y los temas que en ella se debían tratar. Así pues el fin principal del presente trabajo es el análisis de un fenómeno socialmente relevante en el marco de las relaciones internacionales como lo es la configuración de seguridad, a partir de intervenciones de terceros actores que involucran poblaciones afectadas como en el caso somalí, la cual enfrentó una situación de crisis como producto de la emergencia de seguridad que se produce en el año 1991 con la expulsión de Siad Barre del poder. Su importancia radica en la reivindicación de la trascendencia tanto de los derechos humanos, como de la relevancia del papel de las organizaciones internacionales y de los Estados más poderosos del Sistema Internacional, en la protección de esos derechos y de las comunidades vulnerables que conforman dicho sistema.

Objetivo: Establecer la relación entre la percepción de seguridad con los factores ocupacionales y socio demográficos de los trabajadores pertenecientes a 11 clínicas odontológicos particulares en Bogotá. Materiales y métodos: Estudio de corte transversal en población de trabajadores pertenecientes a clínicas odontológicas particulares de Bogotá (Colombia). La muestra incluyó 105 odontólogos y 107 auxiliares pertenecientes a 11 clínicas odontológicas privadas en Bogotá que cumplieron con los criterios de selección. Se incluyeron variables ocupacionales y socio demográficas y las relacionadas con el sistema de seguridad y salud en el trabajo. Se aplicó el “Cuestionario Nórdico Sobre Seguridad en el Trabajo. Para los factores socio-demográficos de la población estudiada, se utilizó estadística descriptiva, medidas de frecuencia absoluta y porcentual, las variables cuantitativas se describieron con medidas de tendencia central y de dispersión; para la asociación de las variables cualitativas con el tipo de percepción se usó la prueba Ji Cuadrado de Pearson o el test exacto de Fisher para valores esperados menores de 5. Resultados: Las dimensiones con mejor percepción fueron las relacionadas con la confianza en la eficacia de los sistemas de seguridad (D7 3.35±0.43) y la Administración de justicia de seguridad (D3 3.1±0.55). Las dimensiones que evalúan la Gestión de empoderamiento de seguridad (D2 2.74±0.99) y la prioridad de los trabajadores con la seguridad (D5 2.64±0.54) tuvieron la menor percepción. La percepción de seguridad fue buena en general teniendo en cuenta que el promedio de todas las dimensiones fue superior a 2.5; percepción mayor significativamente en los hombres (3.78±0.38), odontólogos (3.89±0.38) y personal que tienen o han tenido pareja (3.83±0.4). Las personas con más trabajos adicionales (4.07±0.17), mayor nivel educativo (3.89±0.31), mayor antigüedad laboral (3.92±0.51) y trabajadores mayores de 30 años (3.89±0.35), mostraron mejor percepción de seguridad. En el análisis multivariado los factores cargo y antigüedad laboral encontraron asociación en las dimensiones 2, 4 y 6 (p<0.001), mientras que para las variables numéricas, las dimensiones 1, 3, 4 y 6 tuvieron asociación significativa las variables género y posición (p<0.001). Conclusiones: La percepción de seguridad en las siete dimensiones se relacionó con el género, edad, estado civil, nivel educativo, cargo, posición y antigüedad laboral. No se encontraron diferencias significativas por turno de trabajo o clínica.
