This thesis analyzes how trade secrets can be used as a means to protect knowledge developed through projects conducted in the telecommunications sector. At the same time, the study explores which mechanisms should be employed to regulate access and utilization of trade secrets when their disclosure is inevitable to accomplish project requirements. Telecommunications firms are large and globally distributed organizations whose business operations rely upon interoperability and close collaboration with different parties. This suggests that conducting virtual projects crossing national and cultural boundaries, and sharing information for future survival and development, are common practices within this industry. The purpose of the investigation is to contribute to a certain degree with new knowledge as a basis for future studies in the field given that research around intellectual property issues in the area of project management has been poorly developed. At the same time, studies have been conducted towards patenting as a means to protect technological knowledge in telecommunications whilst trade secrets have not been contemplated by the academia. The study follows a qualitative approach encompassing an extensive literature review and empirical data analysis gathered through interviews. The results from the literature analysis are synthesized in a proposed model covering factors influencing the protection of trade secrets before, during and after project execution. This model also examines the extent to which trade secrets can be used as instruments to secure technological knowledge developed in virtual project setting. The theoretical model is improved with the empirical data collected resulting in an enhanced model which is illustrated in the discussion chapter. Limitations of the study and suggestions for further research are addressed in the last section of this thesis,

Risk aversion in the satellite industry has fostered long development cycles and low rates of innovation in the past. Emerging trends in propulsion technology development and spacecraft architecture design could lead to increased adoption of small satellites as well as more open, flexible and useful space systems. Two particular developments can be used to map the future of the industry. First, the development of MEMS thrusters for launch vehicles could enable dedicated launches for small satellites. This could substantially bring down the cost of satellite deployment. Second, the successful completion of the DARPA System F6 project could demonstrate the value of spacecraft fragmentation. This in turn could shift the focus of the industry from certain attributes that result in long development cycles, thereby opening the doors for open systems and greater innovation. Emerging trends in the satellite industry may result in paradigm shifts that would dramatically decrease satellite costs and increase innovation. This may ultimately result in a structural change in the satellite industry.

El concepto de Internet of Things (IoT por sus siglas en inglés) o Internet de las cosas se define como una evolución del actual internet y tiene el objetivo de permitir a objetos o dispositivos identificables unívocamente en digital, comunicarse con otros dispositivos y sistemas distribuidos a través de internet, utilizando estándares abiertos. Este paradigma permite ofrecer muchos servicios innovativos, pervasivos y ubicuos que encuentran aplicabilidad tanto en sectores tradicionales como automatización o control industrial y en campos más modernos como e-health, sistemas de energía inteligentes, ciudades inteligentes entre otros. Una de las principales tecnologías habilitantes para el IoT es el Tag RFID, de hecho este Tag asociado a un objeto no inteligente, puede identificarlo unívocamente y ser utilizado para memorizar información sobre el objeto mismo. También la estandarización de tecnologías wireless, como las consolidadas Bluetooth y ZigBee y las más recientes 6LoWPAN e COAP han tenido una gran importancia en la difusión del concepto de IoT, porque han permitido tener sensores poco invasivos, sensibles, económicos y muy precisos, los cuales no perturban los parámetros medidos por los otros sensores expuestos cercanamente, pueden ser stand-alone o reagrupados en redes de sensores y pueden funcionar de manera independiente. Tales sensores son utilizados para recoger información en tiempo real sobre parámetros del ambiente, como temperatura, localización, movimiento, etc. Y pueden ser gestionados e integrados en plataformas tecnológicas para el IoT. Sin embargo, estos objetos inteligentes pueden interactuar entre ellos a pesar de las diferencias en términos de hardware, software y protocolos de comunicación usados. Una solución común es utilizar un software especializado conocido como middleware, el cual se trata de un importante componente arquitectural para el soporte de las aplicaciones distribuidas, que usualmente se posiciona entre las aplicaciones y el sistema operativo. El rol del middleware es el de presentar un modelo de programación unificado para programadores y desarrolladores de aplicaciones, enmascarar los problemas de heterogeneidad entre dispositivos y la distribución del software. Vista la complejidad de las plataformas para el internet de las cosas, y teniendo en cuenta varios aspectos importantes para facilitar el uso de tales sistemas y herramientas de configuración que vienen incorporados con ellos, los cuales permiten configurar una instancia del sistema, gestionar el ciclo de vida de los módulos que lo integran y tener una idea clara en tiempo real de su estado de ejecución, facilitando al usuario la fase de commissioning de la plataforma y la fase de configuración de los diferentes componentes principales. El objetivo de esta tesis es extender la actual herramienta de configuración del middleware VIRTUS, basándose sobre las consideraciones hechas estudiando el estado del arte de los métodos para la configuración de arquitecturas de software distribuido. Visto el amplio campo de posibles soluciones, se decidió focalizarse sobre algunas soluciones del sector Smart energy poniendo particular atención sobre el middleware open source LinkSmart. VIRTUS es un middleware orientado al internet de las cosas que usa instrumentos abiertos y estándares que ofrecen una solución escalable, ágil y totalmente event-driven para el soporte de aplicaciones para el internet de las cosas. La arquitectura de VIRTUS prevé un instrumento para la configuración y gestión del middleware, este software permite al usuario interactuar con varios módulos del sistema y controlar en fase de ejecución el ciclo de vida del software, y recuperar el estado de ejecución actual de las aplicaciones. Después de la fase de estudio, se decidió concentrar los desarrollos sobre la funcionalidad de configuración dinámica de aplicaciones multidominio, que permiten la comunicación entre diferentes instancias del middleware, dado que aún no está presente en el sistema de configuración. Además de adicionar esta característica, en el mismo contesto ha sido implementado también un mecanismo de DISCOVERY para permitir al middleware, descubrir cuales sensores están presentes en una instancia remota de VIRTUS y poder escoger aquellos que sean necesarios para completar la configuración de la propia aplicación. Esta última parte ha sido desarrollada a través del protocolo XMPP, protocolos abiertos de mensajería instantánea utilizados en VIRTUS para la comunicación entre las diferentes entidades. El presente trabajo se estructura en 4 capítulos. En el primer capítulo vienen analizados a nivel general los conceptos de Internet de las cosas y middleware, el segundo capítulo describe como pueden clasificarse los middleware y sus diferentes arquitecturas, en el tercer capítulo se presenta el estudio hecho sobre los principales sistemas de configuración y herramientas de gestión en tiempo real, en el ámbito de Smart energy y sobre el middleware LinkSmart, en el último capítulo se describe la arquitectura del middleware VIRTUS y su sistema de configuración, además vienen detallados los desarrollos hechos, las posibles evoluciones y las conclusiones.

Crime and violence have been regarded as one of the main obstacles to development in Latin America countries. Well-known researchers and institutions have studied the impact of violence on health and development in many countries of South America, showing violence as a two-fold constraint, to health and development. Since Colombia has been one of the countries most affected by violence, this dissertation studies violence at the national level and at the municipal level. This research uses a quantitative approach in order to reveal how violence has been occurring in Colombia. Likewise, it uses the city of Bucaramanga as a case study in order to understand how violence, low socioeconomic status and low academic levels are related.Crime and violence have been regarded as one of the main obstacles to development in Latin America countries. Well-known researchers and institutions have studied the impact of violence on health and development in many countries of South America, showing violence as a two-fold constraint, to health and development. Since Colombia has been one of the countries most affected by violence, this dissertation studies violence at the national level and at the municipal level. This research uses a quantitative approach in order to reveal how violence has been occurring in Colombia. Likewise, it uses the city of Bucaramanga as a case study in order to understand how violence, low socioeconomic status and low academic levels are related. This dissertation analyses how interpersonal and collective violence occurs in Colombia (2006 – 2009) and particularly in Bucaramanga (2006). It analyses violence by linking two main rising typologies in Colombia and their most common manifestations. Firstly, it looks at interpersonal violence through child abuse and intimate partner violence; secondly, it focuses on collective violence through homicides. Quantitative analysis is carried out through factors such as age, gender, perpetrators and time to measure manifestations at the national level and the municipal level (Bucaramanga). Furthermore, violence is mapped in Bucaramanga with the purpose of identifying where the most affected areas are. Similarly, it points out deprived areas of Bucaramanga by showing indicators such us socioeconomic status, academic level, public services coverage, which are also mapped. Finally, both maps are overlapped with the aim of understanding links between violence, socioeconomic status and academic level. The research carried out found that there is a close relationship between interpersonal and collective violence and across their manifestations. It also revealed that Bucaramanga shows the same patterns in interpersonal and collective violence as the national level with small variations. Moreover, the research found a close relation between violence, low socioeconomic status and low academic levels in Bucaramanga. This dissertation concludes reviewing successful policies implemented at the municipal level aimed at reducing violence. It uses the successful example of Medellín to recommend possible policies that could reduce crime and violence in Bucaramanga.

Arabinogalactan-proteins (AGPs) or proteoglycans in Green coffee beans (GCB) are characterized by their low levels of extraction. Previous work reported a yield of ~1,1% (w/w) of GCB using hot water extraction. This means over 92% AGP of the coffee beans remains in the residual cell wall material (RCWM) composed of cellulose and mannan. The aim of this research is to increase the extraction of AGP from green coffee beans, applying different extraction methods and to compare the methods based on their yield and the chemical composition of obtained fraction. AGP was extracted by: single extraction using (1) cold (4 °C) or (2) hot water (90°C), (3) enzymatic hydrolysis or by sequential extraction, starting with cold water, followed by (4) hot water or alkali (6M KOH) extraction and enzymatic hydrolysis. Extracted AGP was purified and recovered using a preparative anion exchange column (AEC). AGP fractions were identified with a Yariv radial gel diffusion assay. The highest extraction yield (8,7% AGP) was obtained through sequential extraction using alkali. In this method, the alkali extraction resulting in extraction of 57% of the total AGP extracted with the sequence followed by the enzymatic treatment with a 37%. Two main AGPs were obtained with AEC one unbound and the other bound (both showed positive reaction to Yariv reagent test). In order to elucidate the reasons of having these two different AGPs, molecular size was determined using HPSEC, but clear differences were not observed. A main peak with a molecular weight of 287 kDa was measured for both. Analysis carried out in the composition of AGPs confirmed the majority content of arabinose and galactose and the presence of proteins and uronic acids to a less extent. Protein content was on average 12% (w/w). The carbohydrate moiety accounted between 3 to 7% uronic acids with glucuronic acid being the most predominant. Effect of the extraction method on the structure was reflected in the variation of the ratio Galactose/Arabinose. For instance, AGP from cold water showed a ratio of 2.6 indicating its highly branched nature that eases its solubilization. In contrasts ratio of AGP from the enzymatic treatment in the sequential extraction was around 8, which means a poor branch structure. The difference in the ratios reflects the strength of the treatment applied in the composition of AGP. Therefore studies on the extraction of AGP from coffee beans have to be developed using milder methods to maintain the native structure of the AGP presences in the CWM and therefore reducing the side effects on its structure.

Energy systems entail a dualism: they are absolutely vital for the normal functioning of societies, but the activities related to them are threatening the stability of the natural environment where societies develop (by being the main source of greenhouse gas emissions). Therefore, energy systems need to be maintained and further expanded, whilst simultaneously reducing their negative environmental impacts. In this sense, a deeper understanding of the thermodynamic concepts behind energy use and conversion processes is needed. Exergy and useful work provide such an understanding and hence their analysis can be used as a tool for improved energy policy making, particularly when dealing with efficiency improvements. In consideration of the above, this dissertation first looks into the energy dualism, followed by the description of the conceptual framework which orientates the work. Subsequently this is applied to the analysis of Colombia as an illustrative case study, taking into account data availability and specific features of that country’s energy system, which in themselves provide special analytical interest. Finally, this dissertation discusses methodological issues and results, as well as the energy policy implications derived from the analysis, both in general/conceptual terms and in the specific case of Colombia. As a result, it was found that exergy and useful work analysis is a tool that can complement traditional energy analysis when assessing national energy systems. Exergy and useful work provide significant conceptual improvements, as well as strengthening the comprehension of the whole flow of energy through society. Furthermore, exergy and useful work analysis leads to different energy policy recommendations when compared to the traditional energy based analysis, particularly regarding energy sources for electricity generation, efficiency dilution effects and leapfrogging opportunities.

In 2007, the European Commission recognized “Café de Colombia” as the first non-European Protected Geographical Indication. It was the result of longstanding advertising efforts promoting the Colombian Coffee as a synonym of quality, particularly guaranteeing its singleorigin. Around the indication “Café de Colombia”, economical, cultural, political and social benefits have been achieved. Consequently, this case demonstrates the relevance of indications of geographical origin (IGOs), and the need for adequate measures of protection. Nevertheless, this case also reveals the inconvenient regulation of the TRIPS Agreement regarding this matter. First, the paper demonstrates that the TRIPS Agreement allows the registration of individual Trademarks (TMs) containing or consisting of IGOs, which leads to a symbiosis between two incompatible regimes. As a result, the TRIPS Agreement makes feasible the monopolization of IGOs through TM registration. It also godfathers the potential misleading use of TMs regarding the geographical origin of the products. To support these assertions, it is required to draw a parallel between TM law and the IGO regime. It is also relevant to present the variety of means of protection that national jurisdictions might adopt to implement the TRIPS Agreement, avoiding the registration of individual TMs. Second, the document highlights the discriminatory regulation adopted by the TRIPS Agreement on IGOs, favoring indications for wines and spirits. It studies the origins of such a discriminatory system of protection, to demonstrate that no plausible justification lies on it. Therefore, this paper advocates for the extension of the protection currently reserved to indications for wines and spirits. In doing so, the analysis of “Café de Colombia” results even more eloquent because Colombia, a country famous for its coffee rather than for its production of wines and spirits (in which it has no tradition at all), is part of the opponent group, advocating for the discriminatory two-tiered system adopted by the TRIPS Agreement.

OBJECTIVES: Unintentional asphyxia among preadolescents and adolescents by compression of the neck and other means of inducing hypoxia / anoxia in order to get exhilarating effects are not new or uncommon behaviors and can lead to death by accident. Medical science has described autoerotic asphyxiation and more recently asphyxial games “choking games” as different entities. This study addresses both behaviors to understand the characteristics of how these practices are presented as well as the risks factors to them in order to determine if there are substantial differences between the two practices, or if instead they are related behaviors. Accurate knowledge of these behaviors based on scientific evidence will facilitate the understanding of the etiology and manifested features and facilitate the implementation of preventive measures to avoid such deaths. METHODS: A retrospective study of fatal cases published in recognized scientific journal articles of both autoerotic asphyxiation and choking game behaviors in the adolescent population was made. Articles on sociology, psychoanalysis and psychiatry as well as studies previously published case series and epidemiological studies to assess student population etiological factors and risk factors associated with behaviors were included in this review. Features of both behaviors, such as prevalence, age distribution, gender, type of asphyxia and place of occurrence are presented. RESULTS: The results are consistent in all variables analyzed for both behaviors. Most practitioners are men. Cases of both behaviors in preadolescence show a tendency to increase with age. The most frequent type of asphyxia identified was hanging conducted in private quarters. Psychiatric and psychoanalytic literature identifies common elements between male castration complex, failed oral psychosexual development and the practice of asphyxia in its integration with sociological theories of risk and confrontation ordeal in adolescence. The review of epidemiological studies reveals common elements in the development of both practices in terms of risk factors. CONCLUSIONS: The evidence suggests a link between both practices and allows to theorize that they are part of the same syndrome. Integrating psychoanalytic and sociological concepts as well as the risk factors suggests a linear sequential model of development in four stages: childhood syndrome rope, asphyxial games associated to masturbation, Adolescent autoerotic asphyxia and Adult Autoerotic Asphyxia fetishist / bondage Syndrome. Death is explained in each of the stages as failed physiological and emotional adaptation mechanisms. It is important to disseminate knowledge of these practices among health professionals and further studies should be carried out in regarding deaths by hanging in children and adolescents.

Resumo: A presente tese aborda o processo de pesquisa/criação do espetáculo unipessoal Meus caros amigos, no qual se registra o exercício do ator que passa de intérprete a autor da cena. Trata-se de um estudo sobre as potencialidades do espetáculo unipessoal na consolidação de uma busca pela autoria para o caso do ator. Para conseguir esse propósito, esta tese parte de uma série de pressupostos teóricos que envolve assuntos relacionados com as noções de interpretação e de autoria no contexto da arte teatral e com o que se entende habitualmente como monólogo ou solo, termos também usados para descrever o tipo de experiência cênica que aqui se nomeia como espetáculo unipessoal. A partir disso, empreende-se um processo de criação cênica, o qual se traduz em uma busca pela autonomia do ator que prescinde de outras figuras habituais na tradição teatral, como o dramaturgo ou o encenador, para a criação de um espetáculo do qual ele mesmo possa se considerar o autor. Esse caminho faz com que o pesquisador/criador absorva as funções das figuras dispensadas e fortaleça um discurso próprio construído a partir dos materiais fornecidos pelo seu próprio imaginário. Partindo desse conceito e alimentado pela necessidade de falar sobre suas próprias inquietações, o artista dá início a um processo criativo que encontra na teoria da formatividade de Luigi Pareyson elementos chave para o desenvolvimento das particularidades do seu fazer. Novas associações teóricas acompanham esse percurso, entre elas, o método cartográfico e o princípio de multiplicidade como apresentado por Italo Calvino. A tese conclui com a reflexão sobre as estratégias autorais desenvolvidas no processo criativo e com o reconhecimento de um projeto autoral que extrapola a realidade da cena. Finalmente, o estudo oferece possíveis caminhos para definir as categorias de espetáculo unipessoal e ator-autor no contexto do desenvolvido nesta pesquisa.

Resumen: El objetivo de ésta tesis es dar una base bibliográfica suficiente para identificar estudios, disciplinas y tecnologías vigentes que puedan ser aplicadas a la observación y mejoramiento de los mecanismos biológicos necesarios para tocar contrabajo, y que por tanto aporten a la potenciación de las posibilidades técnicas y artísticas del contrabajista, así como de su salud. En el Capítulo 1 se presenta información considerada clave acerca de las características morfológicas, tanto del cuerpo humano como del contrabajo, a la vez que se introducen algunos ejemplos de la manera en que dichas morfologías, y la interacción entre ellas, aportan a la producción controlada de sonido. En el segundo capítulo se integra al documento información acerca de los trastornos músculo-esqueléticos que aquejan a músicos profesionales. Allí se recogen datos estadísticos referentes los músicos de orquesta, y se focaliza en algunos de los trastornos comunes para los contrabajistas, incluyendo descripciones de condiciones endógenas y exógenas que los originan. En el tercer capítulo se exponen algunas iniciativas investigativas que buscan vincular al panorama del desarrollo musical profesional ciertas perspectivas emergentes: conceptos y disciplinas dedicados a cultivar un buen uso de la asociación humana mente/cuerpo, que muestran un gran potencial, tanto para la prevención y la rehabilitación de trastornos músculo-esqueléticos como para el pulimento de la técnica instrumental. En la cuarta y última fase de la exploración bibliográfica (capítulo 4) se integrará enfáticamente información conteniendo análisis más detallados de las mecánicas corporales en interacción con los objetos, las herramientas, los instrumentos. Abstract: The objective of this document is to give a sufficientbibliographic basis to identify current studies, disciplines and technologies that can be applied to the observation and improvement of the biological mechanisms necessary to touch against Touch double bass, and therefore contribute to the empowerment of the technical and artistic possibilities of the bassist, as well as his health. In this sense, in the first instance (Chapter 1), information is presented that is considered key to the morphological characteristics of both the human body and the double bass, while introducing some examples of how these Morphology, and the interaction between them, contributes to the controlled production of sound. In the second chapter, information on musculoskeletal disorders afflicting professional musicians is integrated into the document. There are collected statistical data concerning orchestral musicians, and focuses on some of the common disorders for the bassists, including descriptions of endogenous and exogenous conditions that originate them. The third chapter sets out some research initiatives that seek to link to the panorama of professional musical development certain emerging perspectives: concepts and disciplines dedicated to cultivating a good use of the human Mind/body Association, which They show great potential, both for the prevention and rehabilitation of musculoskeletal disorders and for the polishing of instrumental techniques. In the fourth and final phase of bibliographic exploration (chapter 4), information will be emphatically integrated containing more detailed analyses of body mechanics in interaction with objects, tools, instruments. It will be sought to make evident the relevance of the use of detailed biomechanical control and analysis tools, for the observation and development of the necessary movements within the instrumental musical activity of the bassist.
