Understanding HCI policy in Spain in the context of acces

Spain pioneered policies related to disability and accessibility, especially in the physical environment. The first major piece of legislation was Act 13/1982 on the Social Integration of People with Disabilities. The law was published just a few years after the reinstitution of democracy in Spain in 1977 and the approval of the Spanish Constitution in 1978. Act 13/1982 is a general law that applies accessibility to social services and education, as well as to workplace and physical accessibility. This law targeted first and foremost the social integration of people with disabilities, and it was a significant success, especially in the field of employment, as it made it mandatory for private companies and public administrations to employ a certain percentage of persons with disabilities. This greatly increased the employability of people with disabilities, as highlighted in a document celebrating 30 years of Act 13/1982. Over the past 20 years, policy makers have also focused on accessibility to information and communication technologies (ICT), developing first the national computing accessibility standards and then specialized legislation. Initially, Spanish activities were mostly national but have now gained an international dimension. All these initiatives are strongly related to the discipline of human-computer interaction, as the key component of an accessible system is its user interface.

A policy-driven architecture for supporting joint degrees through e-learning services

En un mercado de educación superior cada vez más competitivo, la colaboración entre universidades es una efectiva estrategia para acceder al mercado global. El desarrollo de titulaciones conjuntas es un importante mecanismo para fortalecer las colaboraciones académicas y diversificar los conocimientos. Las titulaciones conjuntas están siendo cada vez más implementadas en las universidades de todo el mundo. En Europa, el proceso de Bolonia y el programa Erasmus, están fomentado el reconocimiento de titulaciones conjuntas y dobles y promoviendo la colaboración entre las instituciones académicas. En el imparable proceso de la globalización y convergencia educativa, el uso de sistemas de e-learning para soportar cursos tanto semipresencial como online es una tendencia en crecimiento. Dado que los sistemas de e-learning soportan una amplia variedad de cursos, es necesario encontrar una solución adecuada que permita a las universidades soportar y gestionar las titulaciones conjuntas a través de sus sistemas de e-learning en conformidad con los acuerdos de colaboración establecidos por las universidades participantes. Esta tesis doctoral abordará las siguientes preguntas de investigación: 1. ¿Qué factores deben tenerse en cuenta en la implementación y gestión de titulaciones conjuntas? 2. ¿Cómo pueden los sistemas actuales de e-learning soportar el desarrollo de titulaciones conjuntas? 3. ¿Qué otros servicios y sistemas necesitan ser adaptados por las universidades interesadas en participar en una titulación conjunta a través de sus sistemas de e-learning? La implementación de titulaciones conjuntas a través de sistemas de e-learning es compleja e implica retos técnicos, administrativos, culturales, financieros, jurídicos y de seguridad. Esta tesis doctoral propone una serie de contribuciones que pueden ayudar a resolver algunos de los retos identificados. En primer lugar se ha elaborado un modelo conceptual que incluye la información del contexto de las titulaciones conjuntas que es relevante para la implementación de estas titulaciones en los sistemas de e-learning. Después de definir el modelo conceptual, se ha propuesto una arquitectura basada en políticas para la implementación de titulaciones interinstitucionales a través de sistemas de e-learning de acuerdo a los términos estipulados en los acuerdos de colaboración que son firmados por las universidades participantes. El autor se ha centrado en el componente de gestión de flujos de trabajo de esta arquitectura. Por último y con el fin de permitir la interoperabilidad de repositorios de objetos educativos, los componentes básicos a implementar han sido identificados y validados. El uso de servicios multimedia en educación es una tendencia creciente, proporcionando servicios de e-learning que permiten mejorar la comunicación y la interacción entre profesores y alumnos. Dentro de estos servicios, nos hemos centrado en el uso de la videoconferencia y la grabación de clases como servicios adecuados para el desarrollo de cursos impartidos en escenarios de educación colaborativos. Las contribuciones han sido validadas en proyectos de investigación de ámbito nacional y europeo en los que el autor ha participado. Abstract In an increasingly competitive higher education market, collaboration between universities is an effective strategy for gaining access to the global market. The development of joint degrees is an important mechanism for strengthening academic research collaborations and diversifying knowledge. Joint degrees are becoming increasingly implemented in universities around the world. In Europe, the Bologna process and the Erasmus programme have encouraged both the global recognition of joint and double degrees and promoted close collaboration between academic institutions. In the unstoppable process of globalization and educational convergence, the use of e-learning systems for supporting both blended and online courses is becoming a growing trend. Since e-learning systems covers a wide range of courses, it becomes necessary to find a suitable solution that enables universities to support and manage joint degrees through their e-learning systems in accordance with the collaboration agreements established by the universities involved. This dissertation will address the following research questions: 1. What factors need to be considered in the implementation and management of joint degrees? 2. How can the current e-learning systems support the development of joint degrees? 3. What other services and systems need to be adapted by universities interested in participating in a joint degree through their e-learning systems? The implementation of joint degrees using e-learning systems is complex and involves technical, administrative, security, cultural, financial and legal challenges. This dissertation proposes a series of contributions to help solve some of the identified challenges. One of the cornerstones of this proposal is a conceptual model of all the relevant issues related to the support of joint degrees by means of e-learning systems. After defining the conceptual model, this dissertation proposes a policy-driven architecture for implementing inter-institutional degree collaborations through e-learning systems as stipulated by a collaboration agreement signed by two universities. The author has focused on the workflow management component of this architecture. Finally, the building blocks for achieving interoperability of learning object repositories have been identified and validated. The use of multimedia services in education is a growing trend, providing rich e-learning services that improve the communication and interaction between teachers and students. Within these e-learning services, we have focused on the use of videoconferencing and lecture recording as the best-suited services to support collaborative learning scenarios. The contributions have been validated within national and European research projects that the author has been involved in.

Traditional education vs modern education. What is the impact of teaching techniques' evolution on students learning process?

The main objective of this article is to focus on the analysis of teaching techniques, ranging from the use of the blackboard and chalk in old traditional classes, using slides and overhead projectors in the eighties and use of presentation software in the nineties, to the video, electronic board and network resources nowadays. Furthermore, all the aforementioned, is viewed under the different mentalities in which the teacher conditions the student using the new teaching technique, improving soft skills but maybe leading either to encouragement or disinterest, and including the lack of educational knowledge consolidation at scientific, technology and specific levels. In the same way, we study the process of adaptation required for teachers, the differences in the processes of information transfer and education towards the student, and even the existence of teachers who are not any longer appealed by their work due which has become much simpler due to new technologies and the greater ease in the development of classes due to the criteria described on the new Grade Programs adopted by the European Higher Education Area. Moreover, it is also intended to understand the evolution of students’ profiles, from the eighties to present time, in order to understand certain attitudes, behaviours, accomplishments and acknowledgements acquired over the semesters within the degree Programs. As an Educational Innovation Group, another key question also arises. What will be the learning techniques in the future?. How these evolving matters will affect both positively and negatively on the mentality, attitude, behaviour, learning, achievement of goals and satisfaction levels of all elements involved in universities’ education? Clearly, this evolution from chalk to the electronic board, the three-dimensional view of our works and their sequence, greatly facilitates the understanding and adaptation later on to the business world, but does not answer to the unknowns regarding the knowledge and the full development of achievement’s indicators in basic skills of a degree. This is the underlying question which steers the roots of the presented research.

Metamodelo para la mejora del proceso de gestión de requisitos

El vertiginoso avance de la informática y las telecomunicaciones en las últimas décadas ha incidido invariablemente en la producción y la prestación de servicios, en la educación, en la industria, en la medicina, en las comunicaciones e inclusive en las relaciones interpersonales. No obstante estos avances, y a pesar de la creciente aportación del software al mundo actual, durante su desarrollo continuamente se incurre en el mismo tipo de problemas que provocan un retraso sistemático en los plazos de entrega, se exceda en presupuesto, se entregue con una alta tasa de errores y su utilidad sea inferior a la esperada. En gran medida, esta problemática es atribuible a defectos en los procesos utilizados para recoger, documentar, acordar y modificar los requisitos del sistema. Los requisitos son los cimientos sobre los cuáles se construye un producto software, y sin embargo, la incapacidad de gestionar sus cambios es una de las principales causas por las que un producto software se entrega fuera de tiempo, se exceda en coste y no cumpla con la calidad esperada por el cliente. El presente trabajo de investigación ha identificado la necesidad de contar con metodologías que ayuden a desplegar un proceso de Gestión de Requisitos en pequeños grupos y entornos de trabajo o en pequeñas y medianas empresas. Para efectos de esta tesis llamaremos Small-Settings a este tipo de organizaciones. El objetivo de este trabajo de tesis doctoral es desarrollar un metamodelo que permita, por un lado, la implementación y despliegue del proceso de Gestión de Requisitos de forma natural y a bajo coste y, por otro lado, el desarrollo de mecanismos para la mejora continua del mismo. Este metamodelo esta soportado por el desarrollo herramientas que permiten mantener una biblioteca de activos de proceso para la Gestión de Requisitos y a su vez contar con plantillas para implementar el proceso partiendo del uso de activos previamente definidos. El metamodelo contempla el desarrollo de prácticas y actividades para guiar, paso a paso, la implementación del proceso de Gestión de Requisitos para una Small-Setting utilizando un modelo de procesos como referencia y una biblioteca de activos de proceso como principal herramienta de apoyo. El mantener los activos de proceso bien organizados, indexados, y fácilmente asequibles, facilita la introducción de las mejores prácticas al interior de una organización. ABSTRACT The fast growth of computer science and telecommunication in recent decades has invariably affected the provision of products and services in education, industry, healthcare, communications and also interpersonal relationships. In spite of such progress and the active role of the software in the world, its development and production continually incurs in the same type of problems that cause systematic delivery delays, over budget, a high error rate and consequently its use is lower than expected. These problems are largely attributed to defects in the processes used to identify, document, organize, and track all system's requirements. It is generally accepted that requirements are the foundation upon which the software process is built, however, the inability to manage changes in requirements is one of the principal factors that contribute to delays on the software development process, which in turn, may cause customer dissatisfaction. The aim of the present research work has identified the need for appropriate methodologies to help on the requirement management process for those organizations that are categorised as small and medium size enterprises, small groups within large companies, or small projects. For the purposes of this work, these organizations are named Small-Settings. The main goal of this research work is to develop a metamodel to manage the requirement process using a Process Asset Library (PAL) and to provide predefined tools and actives to help on the implementation process. The metamodel includes the development of practices and activities to guide step by step the deployment of the requirement management process in Small-Settings. Keeping assets organized, indexed, and readily available are a main factor to the success of the organization process improvement effort and facilitate the introduction of best practices within the organization. The Process Asset Library (PAL) will become a repository of information used to keep and make available all process assets that are useful to those who are defining, implementing, and managing processes in the organization.

Caracterización de usuario y tráfico en la evolución de la banda ancha en España

El mundo de las telecomunicaciones evoluciona a gran velocidad, acorde con las necesidades de los usuarios. El crecimiento del número de servicios a través de las conexiones que actualmente utilizamos para conectarnos a Internet (Ej. IPTV) con elevados requerimientos de ancho de banda, que junto a los servicios de nuevo nacimiento (ej. OTT), contribuyen tanto al aumento de la necesidad de mayores velocidades de conexión de los usuarios como a la implantación de nuevos modelos de calidad de servicio. Las redes de datos de banda ancha (fija y móvil) actuales deben, por lo tanto, experimentar una profunda transformación para conseguir solventar de una forma eficiente los problemas y las necesidades de tráfico, pudiendo así absorber el progresivo incremento del ancho de banda, dejando las puertas abiertas a futuras mejoras. Y para ello las operadoras se nutrirán con la valiosa información de tráfico y usuario que les lleven a tomar las mejores decisiones de cara a que las transformaciones llevadas a cabo cubran exactamente lo que el usuario demanda de la forma más eficiente posible. Con estas premisas, surgieron las ideas que se plasmaron como objetivos del PFC : La idea de narrar el despliegue de la banda ancha en España desde sus orígenes hasta la actualidad, enfocando su crecimiento desde un punto de vista sociotecnológico. Dando continuidad al punto anterior, se persiguió la idea de conocer las herramientas sociales y tecnológicas a raíz de las cuales se pueda realizar una previsión del tráfico en las redes de las operadoras en un futuro cercano. La pretensión de mostrar las características de los usuarios de banda ancha y del tráfico de datos que generan, que son de carácter crítico para las operadoras en la elaboración de forma adecuada de la planificación de sus redes. La intención de revelar los procedimientos de las operadoras para que, una vez conocidas las características de sus usuarios, se puedan cumplir los requisitos demandados por los mismos: QoS y los indicadores clave de rendimiento (KPIs) Por otro lado, el nivel de detalle dado pretende adecuarse a un público que no tenga profundos conocimientos sobre la materia, y salvo partes bastante concretas, se puede catalogar este trabajo como de abierto al público en general. ABSTRACT. The world of telecommunications is evolving at high speed, according to the needs of users. The growing of services number through the connections that currently have been used to connect to the Internet (eg IPTV ) with high bandwidth requirements, which together with the new birth services (eg OTT ) contribute both to increased the need for higher connection speeds users and the implementation of new models of service quality. Data networks broadband (fixed and mobile ) today must , therefore, undergo a deep transformation to achieve an efficient solving problems and traffic needs, thus being able to absorb the gradual increase of bandwidth, leaving the door open to future improvements. And for that the operators will be nurtured with valuable information and user traffic that lead them to make better decisions in the face of the transformations carried out exactly meet the user demand for the most efficient possible way. With these assumptions, the ideas that emerged were expressed as PFC objectives : The idea of narrating the broadband deployment in Spain from its origins to the present, focusing its growth from a socio-technological approach. Continuing the previous point, it pursued the idea of knowing the social tools and technology as a result of which it can perform a traffic forecast operators networks in the near future. The attempt to show the characteristics of broadband users and data traffic they generate, which are mission critical for operators in developing adequately planning their networks. The intention to disclose procedures for operators, once known the characteristics of their users, it can meet the requirements demanded by them: QoS and key performance indicators (KPI). On the other hand, the level of detail given suit seeks an audience that does not have deep knowledge on the subject, unless quite specific parts, this work can be classified as open to the general public.

Building sustainable capacity for health research in africa through cloud computing applications

Access to information and continuous education represent critical factors for physicians and researchers over the world. For African professionals, this situation is even more problematic due to the frequently difficult access to technological infrastructures and basic information. Both education and information technologies (e.g., including hardware, software or networking) are expensive and unaffordable for many African professionals. Thus, the use of e-learning and an open approach to information exchange and software use have been already proposed to improve medical informatics issues in Africa. In this context, the AFRICA BUILD project, supported by the European Commission, aims to develop a virtual platform to provide access to a wide range of biomedical informatics and learning resources to professionals and researchers in Africa. A consortium of four African and four European partners work together in this initiative. In this framework, we have developed a prototype of a cloud-computing infrastructure to demonstrate, as a proof of concept, the feasibility of this approach. We have conducted the experiment in two different locations in Africa: Burundi and Egypt. As shown in this paper, technologies such as cloud computing and the use of open source medical software for a large range of case present significant challenges and opportunities for developing countries, such as many in Africa.

Sistema de guía para personas invidentes a través de bluetooth

El planteamiento inicial era proveer al individuo invidente de un sistema autónomo capaz de guiarle según sus preferencias. El resultado obtenido al finalizar este proyecto ha sido un dispositivo autónomo configurable por el usuario mediante una aplicación sw , desarrollada en la plataforma móvil Android capaz de comunicarse con el dispositivo autónomo(móvil personal). La idea de utilizar como plataforma de desarrollo sw Android, se basó fundamentalmente en que es código open source, es gratuito y está presente en el 70 por ciento de los móviles de Europa. La idea inicial era que ambos hubieran sido integrados en un mismo dispositivo, pero una vez comenzado el proyecto y habiendo evaluado los hábitos actuales, decidimos adaptar la idea general del proyecto, a nuestros días. Para ello hicimos uso del dispositivo móvil más usado hoy en día, como es nuestros teléfonos móviles, o más bien los llamado Smartphone, con los cuales podemos desde su aplicación originaria que es llamar, hasta realizar multitud de operaciones al mismo tiempo como puede ser comunicación por internet, posicionamiento via GPS, intercambio de ficheros por bluetooth… tantas como podamos programar. Sobre este último atributo, intercambio de información a través de bluetooth, es la interfaz que vamos a aprovechar para la realización de nuestro proyecto. Hoy en día el 90% de los Smartphone tiene entre sus características de conectividad la posibilidad de intercambiar información vía bluetooth. Una vez se tiene resuelto el interfaz entre el medio y el usuario se debe solucionar la forma de transformar la información para que los dispositivos móviles recojan la información y sepan discernir entre la información importante y la que no lo es. Para ello hemos desarrollado una tarjeta configurable, con un módulo bluetooth comercial para enviar la información. El resultado final de esta tarjeta proporciona una manera fácil de configurar diferentes mensajes que serán utilizados según la situación. ABSTRACT The initial approach consisted of a system that shows the way for blind people to get somewhere or something or provide to them important information, an autonomous system able to guide to their preference. After several analyses the project accomplish is a standalone device configurable by the user via an application sw, developed in Android mobile platform capable of communicating with the standalone device (personal cell phone). The decision of using the sw development platform of Android was due to the open source code concept and the great extent of presence on 70 percent of European mobiles. The first idea was that the sw and the device were integrated into a single device, but once the project had been started and having assessed the current habits, it has changed to be adapted to the present technology to get a better usability on the present-day. To achieve the project goals the most used mobile device today was used, our mobile phones, or rather called Smartphone, which you could use to phone your mother or perform many operations simultaneously such as communication online, positioning via GPS, bluetooth file trading program, etc. On this last attribute, information sharing via bluetooth, is the interface that it has been taken to complete the project. Today 90% of the Smartphone include in its connectivity features the ability to exchange information via bluetooth. Once that it was solved the interface between the environment and the final user, the next step incorporates the transformation of the information that the mobile devices collect from the environment to discern between the information the user configure to be notified or not. The hardware device that makes it possible is a configurable card with a bluetooth module that is able to send the information. The final result of this card provides an easy way to configure different messages, that we could use depending of the situation.

Comparisson of hydrogen applications for storage and energy vector

For the decades to come can be foreseen that electricity and water will keep be playing a key role in the countries development, both can be considered the most important energy vectors and its control can be crucial for governments, companies and leaders in general. Energy is essential for all human activities and its availability is critical to economic and social development. In particular, electricity, a form of energy, is required to produce goods, to provide medical assistance and basic civic services in education, to assure availability of clean water, to create conducive environment for prosperity and improvement, and to keep an acceptable quality of life. The way in which electricity is generated from different resources varies through the different countries. Nuclear energy controlled within reactors to steam production, gas, fuel-oil and coal fired in power stations, water, solar and wind energy among others are employed, sometimes not very efficiently, to produce electricity. The so call energy mix of an individual country is formed up by the contribution of each resource or form of energy to the electricity generation market of the so country. During the last decade the establishment of proper energy mixes for countries has gained much importance, and energy drivers should enforce long term plans and policies. Hints, reports and guides giving tracks on energy resources contribution are been developed by noticeable organisations like the IEA (International Energy Agency) or the IAEA (International Atomic Energy Agency) and the WEC (World Energy Council). This paper evaluates energy issues the market and countries are facing today regarding energy mix scheduling and panorama. This paper revises and seeks to improve methodology available that are applicable on energy mix plan definition. Key Factors are identified, established and assessed through this paper for the common implementation, the themes driving the future energy mix methodology proposal. Those have a clear influence and are closely related to future environmental policies. Key Factors take into consideration sustainability, energy security, social and economic growth, climate change, air quality and social stability. The strength of the Key Factors application on energy system planning to different countries is contingent on country resources, location, electricity demand and electricity generation industry, technology available, economic situation and prospects, energy policy and regulation

Modelo de análisis organizativo para la mejora del desempeño de empresas sociales

La empresa social es un modelo organizativo que presenta un interesante potencial para resolver problemáticas sociales. La empresa social ha despertado interés tanto en países industrializados como en economías en vías de desarrollo porque representa un modelo dentro del capitalismo que persigue objetivos sociales mediante la realización de actividades de mercado (compra y venta de productos y/o servicios principalmente). A pesar de sus raíces lejanas en el tiempo se trata de un campo de conocimiento relativamente joven, donde la literatura académica presenta escasez de estudios empíricos. El desarrollo teórico para buscar claridad conceptual ha sido el principal caballo de batalla de los últimos años, y por tanto, se ha prestado poca atención a generar evidencias sobre cómo funcionan las empresas sociales y sobre sus claves de su éxito. Se considera que la mejora en la comprensión de este modelo organizativo pasa por la construcción de herramientas para que académicos y practicantes mejoren su conocimiento sobre los mecanismos internos de las empresas sociales. En este contexto nace la presente tesis doctoral sobre empresa social, que tiene por objetivo la creación de un marco de análisis que permita el estudio de las empresas sociales desde una dimensión organizativa, es decir, que aborde los elementos clave que describen el funcionamiento de este tipo de organizaciones. Para ello, en este trabajo se aborda la construcción del modelo para el análisis organizativo de las empresas sociales a partir del análisis semántico de las 45 principales definiciones de empresa social. A partir de este análisis se identifican dos dimensiones de análisis de la empresa social: -Cuatro principios, comunes a todas las manifestaciones del fenómeno, que recogen la esencia del concepto. -Ocho elementos organizativos específicos de la empresa social que describen la forma en la que cada iniciativa se implementa en un contexto determinado. Es decir, elementos de diseño presentes en diferente medida que dan lugar a tipologías de empresa social diferentes. Estos elementos son: la proposición de valor social, la búsqueda de impacto a largo plazo, la cultura organizativa, la conexión con los beneficiarios, el liderazgo emprendedor y los mecanismos de gobernanza, el ecosistema colaborativo, la estrategia empresarial y la orientación a la autosuficiencia económica. A partir de este marco de análisis, se construyen dos herramientas de diagnóstico que permiten su aplicación al estudio de empresas sociales: una tabla de indicadores para el análisis externo (por parte de un investigador ajeno a la organización) y un cuestionario de diagnóstico para el análisis interno (a través del personal de la empresa social objeto de estudio). Las herramientas intentan dar respuesta a la necesidad de desarrollar constructos para el estudio empírico de las empresas sociales. Para analizar la utilidad del modelo y de las herramientas se llevaron a cabo tres estudios de caso: -La empresa social ACCIONA Microenergía Perú que proporciona energía eléctrica a comunidades rurales aisladas en la región peruana de Cajamarca. -La empresa social Integra-e que propone un mecanismo de inserción socio-laboral en Madrid para jóvenes en riesgo de exclusión a través de la formación en Tecnologías de la Información y la Comunicación (TIC). -Un conjunto de redes de telecentros pertenecientes a la red LAC de la fundación Telecentres.org que proporcionan acceso a servicios de información (Internet entre otros) en diferentes países de Latinoamérica. La aplicación de las herramientas mostró ser útil en los tres estudios de caso para obtener una relación de evidencias con las que analizar la proximidad de una organización al ideal de empresa social. El ejercicio de análisis también resultó interesante como ejercicio reflexivo para las entidades participantes. Los resultados del cuestionario fueron especialmente interesantes en los telecentros de la Fundación Telecentre.org ya que al ser un estudio multicaso se pudo realizar un rico análisis estadístico sobre el funcionamiento de los telecentros y su desempeño. El estudio permitió identificar relaciones interesantes entre los ocho elementos de diseño del modelo propuesto y el desempeño de la organización. En particular, se detectó que para todos los casos estudiados: -La dimensión económica es la componente del desempeño que mayor desafíos plantea. -La existencia de una alta correlación entre el desempeño y siete de los ocho elementos organizativos del modelo. -La importancia de la cultura organizativa como elemento que explica el desempeño global de la organización y la satisfacción de los empleados. El campo de la empresa social presenta importantes retos de futuro, como la claridad conceptual, el desarrollo de estudios empíricos y la medida de su impacto social. El conocimiento de las claves organizativas puede ayudar a diseñar empresas sociales más robustas o a que organizaciones con fines sociales que no se basan en mecanismos de mercado consideren la posibilidad de incorporar éstos en su estrategia. ABSTRACT Social enterprise is an organizational model with a strong potential to help solving social problems. Recently, interest for the model has risen in both industrialized and developing countries because it is organized to achieve altruistic or social goals through market activities (mainly sales of products and services). Despite its historic roots, it is a relatively young field of research, where academic literature has little empirical data to accompany the theoretical development of social enterprise. Conceptual clarification has been the main challenge during the recent years, and there has been little attention given to generate evidence on how social enterprises operate and their keys to success. Progress in empirical study involves the construction of tools for researchers, in order to increase understanding of the internal mechanisms of social enterprises. This thesis aims to create a conceptual framework to study social enterprises from an organizational point of view, by analyzing the key elements that explain the operation and organization of this organizational model. The framework for the organizational analysis of social enterprises was built supported by the semantic analysis of 45 main definitions of social enterprise. The framework is divided into two dimensions: -There are four principles which capture the essence of the social enterprise concept, and are present in the manifestations of cases. -There are eight design elements which help analyze the characteristics of each particular social enterprise initiative: the social value proposition, social impact orientation, organizational culture, links to beneficiaries, entrepreneurial leadership, collaborative ecosystem, entrepreneurial strategy and orientation to economic self-sufficiency. Two diagnostic tools were developed to apply the framework to case studies: a scoreboard of indicators (to be used by the researcher during external analysis of the organization) and a questionnaire (to be answered by the social enterprise staff). The dissertation undertakes the study of three case studies: -ACCIONA Microenergia Peru, a social enterprise that provides electricity to isolated rural communities in the Peruvian region of Cajamarca. -Integra-e, a social enterprise located in Madrid that promotes socioprofessional integration of young people through training in ICT. -A sample of telecenters of the LAC network that provide access to information services (such as Internet) in Latin America. Applying the tools proved to be useful in all three cases, because it helped to obtain evidence to compare the proximity of an organization to an ideal type of social enterprise. In all the cases studied, the economic sustainability proved to be the biggest challenge for the organizations. The application of the questionnaire to the telecenters was especially informative because it was a multicase study which provided a rich statistical analysis on the performance of call centers. The study identified unique relationships between the model elements and the organziation performance. A statistical analysis shows a high correlation between performance and seven organizational elements described in the model. The organizational culture seems to be an important factor in explaining the overall organizational performance and employee satisfaction. The field of social enterprise has significant future challenges -such as conceptual clarity, the development of empirical studies and social impact assessment. A deep understanding of key organizational aspects of social enterprises can help in the design of more robust organizations and to bring success to social-purpose organizations.

Desarrollo de herramienta de generación de Linked Data Educativo

El proyecto nace de un proyecto anterior donde se construyó un modelo para representar la información de los estudios superiores mediante una red de ontologías, proporcionando una definición común de conceptos importantes. Este proyecto consiste en desarrollar una herramienta capaz de generar datos educativos, a partir de la red de ontologías mencionadas anteriormente, siguiendo el paradigma de Linked Data [1]. La herramienta deberá extraer datos de diferentes fuentes educativas y transformará dichos datos educativos a datos enlazados (Linked Data). Para llevar a cabo esta labor se ha utilizado GATE Developer [2], es un entorno de desarrollo que proporciona un completo conjunto de herramientas gráficas interactivas para la creación, medición y mantenimiento de componentes de software para el procesamiento del lenguaje humano.---ABSTRACT---The project arises from a previous project in which a model was constructed to represent information of higher education through a network of ontologies, providing a common definition of important concepts.
