Service innovation: Inward and outward related activities and cooperation mode

Knowledge of how customers co-create value, the way that suppliers and providers co-produce services, and how research and development centers and universities transfer technologies is becoming increasingly important to scholars' understanding of service innovation. This paper presents an analysis of the relationship between inward and outward innovation activities in service organizations and their modes of innovation, using network innovation premises and an extended innovation model. Empirical data from retail, health and education sector service organizations show the existence of a relationship between the degree of development of the inward innovation process and the degree of development of outward innovation activities. The majority of service organizations have innovation processes with an orientation toward customers and suppliers rather than other service network members, and leading service organizations follow a path that the literature defines as oriented toward the service value network. Findings lead to implications of how innovation managers could develop their internal innovation capacity to balance inward and outward activities properly.

Survey on student motivation and approval of educational environment at Universidad Politécnica de Madrid within the European Higher Education area implementation

A recent study elaborated by Vicerrectorado de Ordenación Académica y Planificación Estratégica of Technical University of Madrid (UPM) defines the satisfaction of the university student body as "the response that the University offers to the expectations and demands of service of the students, considered in a general way ". Besides an indicator of academic and institutional insertion of the student, the assessment of student engagement allows us to adapt the academic offer and the extension services of the University to the real needs of the students. The process of convergence towards the European Higher Education Area (EHEA) raises the need to form in competitions, that is to say, of developing in our students capacities and knowledge beyond the purely theoretical-practical thing. Therefore, the perception and experience of the educational process and environment by the students is an important issue to be addressed to accomplish their expectations and achieve a curriculum accordingly to EHEA expectations. The present study aims to explore the student motivation and approval of the educational environment at the UPM. To this end a total of 97 students enrolled in the undergraduate program of Civil Engineering, Computer Engineering and Agronomic Engineering at UPM were surveyed. The survey consisted of 40 questions divided in three blocks. The first one of 20 questions of personal character in that they were gathering, besides the sex and the age, the degree of fulfilment, implication and dedication with the institution and the academic tasks. In the second block we identify 10 questions related to the perception of the student on the teaching quality, and finally a block of 10 questions regarding the Bologna Process. The students personal motivation was moderately high, with a score of 3.6 (all scores are provided on a 5-point scale), being the most valuable items obtaining a university degree (4,3) and the friendship between students (4,2). Any significant difference was shown between sexes (P=0.23) since the averages for this block of questions were of 3.7±0.3 and 3.5±0.4 for women and men respectively. The students are moderately satisfied with their graduate studies with an average score of 3,2, being the questions that reflect a minor satisfaction the research profile of the teachers (2,8) and the organization of the Schools (2,9). The best valued questions are related to the usefulness and quality of the degrees, with 3,5 and 3,4 respectively, and to the interest of the courses within the degree (3,4). For sexes, the results of this block of questions are similar (3.1±0.3 and 3.2±0.3 for men and women respectively=0.79). Also, there were no differences (P=0.39) between the students who arrange work and studies or do not work (3.1±0.2 and 3.2±0.3 respectively). In conclusion, students at UPM present an acceptable degree of motivation and satisfaction with regard to the studies and services that offer their respective Schools. Both characteristics receive the same value both for men and for women and so much for students who arrange work and studies as for those who devote themselves only to studying. In a significant way, students who are more engaged and are in-class attendants present the major degree of satisfaction.Overall, there is a great lack of information regarding the Bologna Process. In fact to the majority, they would like to know more on what it is, what it means and what changes will involve its implementation.

iCarer Project: Intelligent Care Guidance and Learning Services Platform for Informal Carers of the Elderly

The increasing ageing population is demanding new care approaches to maintain the quality of life of elderly people. Informal carers are becoming crucial agents in the care and support of elderly people, which can lead to those carers suffering from additional stress due to competing priorities with employment or due to lack of knowledge about elderly people?s care needs. Thus, support and stress relief in carers should be a key issue in the home-care process of these older adults. Considering this context, this work presents the iCarer project aimed at developing a personalized and adaptive platform to offer informal carers support by means of monitoring their activities of daily care and psychological state, as well as providing an orientation to help them improve the care provided. Additionally, iCarer will provide e-Learning services and an informal carers learning network. As a result, carers will be able to expand their knowledge, supported by the experience provided by expert counsellors and fellow carers. Additionally, the coordination between formal and informal carers will be improved, offering the informal carers flexibility to organize and combine their assistance and social activities.

Modelling the Impact of Built Environment, Geographical Scales and Latent Constructs On Individual Travel Behaviour

La relación entre la estructura urbana y la movilidad ha sido estudiada desde hace más de 70 años. El entorno urbano incluye múltiples dimensiones como por ejemplo: la estructura urbana, los usos de suelo, la distribución de instalaciones diversas (comercios, escuelas y zonas de restauración, parking, etc.). Al realizar una revisión de la literatura existente en este contexto, se encuentran distintos análisis, metodologías, escalas geográficas y dimensiones, tanto de la movilidad como de la estructura urbana. En este sentido, se trata de una relación muy estudiada pero muy compleja, sobre la que no existe hasta el momento un consenso sobre qué dimensión del entorno urbano influye sobre qué dimensión de la movilidad, y cuál es la manera apropiada de representar esta relación. Con el propósito de contestar estas preguntas investigación, la presente tesis tiene los siguientes objetivos generales: (1) Contribuir al mejor entendimiento de la compleja relación estructura urbana y movilidad. y (2) Entender el rol de los atributos latentes en la relación entorno urbano y movilidad. El objetivo específico de la tesis es analizar la influencia del entorno urbano sobre dos dimensiones de la movilidad: número de viajes y tipo de tour. Vista la complejidad de la relación entorno urbano y movilidad, se pretende contribuir al mejor entendimiento de la relación a través de la utilización de 3 escalas geográficas de las variables y del análisis de la influencia de efectos inobservados en la movilidad. Para el análisis se utiliza una base de datos conformada por tres tipos de datos: (1) Una encuesta de movilidad realizada durante los años 2006 y 2007. Se obtuvo un total de 943 encuestas, en 3 barrios de Madrid: Chamberí, Pozuelo y Algete. (2) Información municipal del Instituto Nacional de Estadística: dicha información se encuentra enlazada con los orígenes y destinos de los viajes recogidos en la encuesta. Y (3) Información georeferenciada en Arc-GIS de los hogares participantes en la encuesta: la base de datos contiene información respecto a la estructura de las calles, localización de escuelas, parking, centros médicos y lugares de restauración. Se analizó la correlación entre e intra-grupos y se modelizaron 4 casos de atributos bajo la estructura ordinal logit. Posteriormente se evalúa la auto-selección a través de la estimación conjunta de las elecciones de tipo de barrio y número de viajes. La elección del tipo de barrio consta de 3 alternativas: CBD, Urban y Suburban, según la zona de residencia recogida en las encuestas. Mientras que la elección del número de viajes consta de 4 categorías ordinales: 0 viajes, 1-2 viajes, 3-4 viajes y 5 o más viajes. A partir de la mejor especificación del modelo ordinal logit. Se desarrolló un modelo joint mixed-ordinal conjunto. Los resultados indican que las variables exógenas requieren un análisis exhaustivo de correlaciones con el fin de evitar resultados sesgados. ha determinado que es importante medir los atributos del BE donde se realiza el viaje, pero también la información municipal es muy explicativa de la movilidad individual. Por tanto, la percepción de las zonas de destino a nivel municipal es considerada importante. En el contexto de la Auto-selección (self-selection) es importante modelizar conjuntamente las decisiones. La Auto-selección existe, puesto que los parámetros estimados conjuntamente son significativos. Sin embargo, sólo ciertos atributos del entorno urbano son igualmente importantes sobre la elección de la zona de residencia y frecuencia de viajes. Para analizar la Propensión al Viaje, se desarrolló un modelo híbrido, formado por: una variable latente, un indicador y un modelo de elección discreta. La variable latente se denomina “Propensión al Viaje”, cuyo indicador en ecuación de medida es el número de viajes; la elección discreta es el tipo de tour. El modelo de elección consiste en 5 alternativas, según la jerarquía de actividades establecida en la tesis: HOME, no realiza viajes durante el día de estudio, HWH tour cuya actividad principal es el trabajo o estudios, y no se realizan paradas intermedias; HWHs tour si el individuo reaiza paradas intermedias; HOH tour cuya actividad principal es distinta a trabajo y estudios, y no se realizan paradas intermedias; HOHs donde se realizan paradas intermedias. Para llegar a la mejor especificación del modelo, se realizó un trabajo importante considerando diferentes estructuras de modelos y tres tipos de estimaciones. De tal manera, se obtuvieron parámetros consistentes y eficientes. Los resultados muestran que la modelización de los tours, representa una ventaja sobre la modelización de los viajes, puesto que supera las limitaciones de espacio y tiempo, enlazando los viajes realizados por la misma persona en el día de estudio. La propensión al viaje (PT) existe y es específica para cada tipo de tour. Los parámetros estimados en el modelo híbrido resultaron significativos y distintos para cada alternativa de tipo de tour. Por último, en la tesis se verifica que los modelos híbridos representan una mejora sobre los modelos tradicionales de elección discreta, dando como resultado parámetros consistentes y más robustos. En cuanto a políticas de transporte, se ha demostrado que los atributos del entorno urbano son más importantes que los LOS (Level of Service) en la generación de tours multi-etapas. la presente tesis representa el primer análisis empírico de la relación entre los tipos de tours y la propensión al viaje. El concepto Propensity to Travel ha sido desarrollado exclusivamente para la tesis. Igualmente, el desarrollo de un modelo conjunto RC-Number of trips basado en tres escalas de medida representa innovación en cuanto a la comparación de las escalas geográficas, que no había sido hecha en la modelización de la self-selection. The relationship between built environment (BE) and travel behaviour (TB) has been studied in a number of cases, using several methods - aggregate and disaggregate approaches - and different focuses – trip frequency, automobile use, and vehicle miles travelled and so on. Definitely, travel is generated by the need to undertake activities and obtain services, and there is a general consensus that urban components affect TB. However researches are still needed to better understand which components of the travel behaviour are affected most and by which of the urban components. In order to fill the gap in the research, the present dissertation faced two main objectives: (1) To contribute to the better understanding of the relationship between travel demand and urban environment. And (2) To develop an econometric model for estimating travel demand with urban environment attributes. With this purpose, the present thesis faced an exhaustive research and computation of land-use variables in order to find the best representation of BE for modelling trip frequency. In particular two empirical analyses are carried out: 1. Estimation of three dimensions of travel demand using dimensions of urban environment. We compare different travel dimensions and geographical scales, and we measure self-selection contribution following the joint models. 2. Develop a hybrid model, integrated latent variable and discrete choice model. The implementation of hybrid models is new in the analysis of land-use and travel behaviour. BE and TB explicitly interact and allow richness information about a specific individual decision process For all empirical analysis is used a data-base from a survey conducted in 2006 and 2007 in Madrid. Spatial attributes describing neighbourhood environment are derived from different data sources: National Institute of Statistics-INE (Administrative: municipality and district) and GIS (circular units). INE provides raw data for such spatial units as: municipality and district. The construction of census units is trivial as the census bureau provides tables that readily define districts and municipalities. The construction of circular units requires us to determine the radius and associate the spatial information to our households. The first empirical part analyzes trip frequency by applying an ordered logit model. In this part is studied the effect of socio-economic, transport and land use characteristics on two travel dimensions: trip frequency and type of tour. In particular the land use is defined in terms of type of neighbourhoods and types of dwellers. Three neighbourhood representations are explored, and described three for constructing neighbourhood attributes. In particular administrative units are examined to represent neighbourhood and circular – unit representation. Ordered logit models are applied, while ordinal logit models are well-known, an intensive work for constructing a spatial attributes was carried out. On the other hand, the second empirical analysis consists of the development of an innovative econometric model that considers a latent variable called “propensity to travel”, and choice model is the choice of type of tour. The first two specifications of ordinal models help to estimate this latent variable. The latent variable is unobserved but the manifestation is called “indicators”, then the probability of choosing an alternative of tour is conditional to the probability of latent variable and type of tour. Since latent variable is unknown we fit the integral over its distribution. Four “sets of best variables” are specified, following the specification obtained from the correlation analysis. The results evidence that the relative importance of SE variables versus BE variables depends on how BE variables are measured. We found that each of these three spatial scales has its intangible qualities and drawbacks. Spatial scales play an important role on predicting travel demand due to the variability in measures at trip origin/destinations within the same administrative unit (municipality, district and so on). Larger units will produce less variation in data; but it does not affect certain variables, such as public transport supply, that are more significant at municipality level. By contrast, land-use measures are more efficient at district level. Self-selection in this context, is weak. Thus, the influence of BE attributes is true. The results of the hybrid model show that unobserved factors affect the choice of tour complexity. The latent variable used in this model is propensity to travel that is explained by socioeconomic aspects and neighbourhood attributes. The results show that neighbourhood attributes have indeed a significant impact on the choice of the type of tours either directly and through the propensity to travel. The propensity to travel has a different impact depending on the structure of each tour and increases the probability of choosing more complex tours, such as tours with many intermediate stops. The integration of choice and latent variable model shows that omitting important perception and attitudes leads to inconsistent estimates. The results also indicate that goodness of fit improves by adding the latent variable in both sequential and simultaneous estimation. There are significant differences in the sensitivity to the latent variable across alternatives. In general, as expected, the hybrid models show a major improvement into the goodness of fit of the model, compared to a classical discrete choice model that does not incorporate latent effects. The integrated model leads to a more detailed analysis of the behavioural process. Summarizing, the effect that built environment characteristics on trip frequency studied is deeply analyzed. In particular we tried to better understand how land use characteristics can be defined and measured and which of these measures do have really an impact on trip frequency. We also tried to test the superiority of HCM on this field. We can concluded that HCM shows a major improvement into the goodness of fit of the model, compared to classical discrete choice model that does not incorporate latent effects. And consequently, the application of HCM shows the importance of LV on the decision of tour complexity. People are more elastic to built environment attributes than level of services. Thus, policy implications must take place to develop more mixed areas, work-places in combination with commercial retails.

Communication Architecture for Tracking and Interoperable Services at Hospitals: A Real Deployment Experience

Any new hospital communication architecture has to support existing services, but at the same time new added features should not affect normal tasks. This article deals with issues regarding old and new systems’ interoperability, as well as the effect the human factor has in a deployed architecture. It also presents valuable information, which is a product of a real scenario. Tracking services are also tested in order to monitor and administer several medical resources.

The dicode workbench: A flexible framework for the integration of information and web services

Aiming to address requirements concerning integration of services in the context of ?big data?, this paper presents an innovative approach that (i) ensures a flexible, adaptable and scalable information and computation infrastructure, and (ii) exploits the competences of stakeholders and information workers to meaningfully confront information management issues such as information characterization, classification and interpretation, thus incorporating the underlying collective intelligence. Our approach pays much attention to the issues of usability and ease-of-use, not requiring any particular programming expertise from the end users. We report on a series of technical issues concerning the desired flexibility of the proposed integration framework and we provide related recommendations to developers of such solutions. Evaluation results are also discussed.

Water, agriculture and ecosystem services in climate change vulnerable agricultural regions of Spain and Jordan

Irrigated agricultural landscapes generate a valuable set of ecosystem services, which are threatened by water scarcity in many aridand semi‐arid regions of the world. In the Mediterranean region, climate change is expected to decrease water availability through reduced precipitation and more frequent drought spells. At the same time, climate change, demographic and economic development and an agricultural sector highly dependent on irrigation, will raise water demand, increasing experienced water scarcity and affecting the provision of ecosystem services from water resources and agro-ecosystems. In this context, policy makers face the challenge of balancing the provision of different ecosystem services, including agricultural income and production and also water ecosystem protection.

Analysing trade-offs between food production and ecosystem services in tropical forests of lowland Bolivia

The expansion of agricultural land is responsible for most tropical deforestation. Historically, smallholder farming and shifting cultivation has been reported as the main agent of deforestation. However, the increasing global demand for food in recent years has greatly boosted the development of medium and large-scale commercial agriculture which is nowadays causing the majority of tropical forest cover loss, particularly in Latin America.

La Ordenación del Territorio en las Ciudades Globales Europeas: El caso de Madrid

En la Comunidad de Madrid el modelo de ocupación del territorio en las dos últimas décadas ha obedecido a factores de oferta del mercado y no a las necesidades de la población, ello provoca un consumo de suelo y de recursos que conducen a una sobrexplotación insostenible. Las metrópolis globales están experimentando rápidas e intensas transformaciones, basadas en los paradigmas emergentes de la globalización, la gobernanza, la metropolizacion y la dispersión de las actividades en el territorio y a través de ellos se abordan los planes de Londres, París y las tentativas de Madrid. La globalización provoca la pérdida de soberanía de las administraciones publicas y la competitividad entre las ciudades globales en Europa, Londres, Paris y Madrid, son centros de poder, de concentración y crecimiento donde se produce la dualización del espacio y donde la desigualdad participa de la restructuración urbana, concentración de pobreza frente a espacios de la nueva clase emergente en donde dominan los sectores de servicios y las tecnologías de la información. Frente al desarrollo urbano neoliberal de regulación a través del mercado y basada en criterios de eficiencia de la Nueva Gestión Pública, se vislumbra la posibilidad de que la sociedad se administre a si misma por medio de acciones voluntarias y responsables que promuevan los intereses colectivos mediante el reconocimiento de su propia identidad, introduciendo el concepto de gobernanza. Frente, a la explotación del territorio por parte de la sociedad extractiva que genera corrupcion, se propone un modelo de cooperación público-privada basado en la confianza mutua, un marco regulador estable, la transparencia y la información a cuyo flujo más homogéneo contribuirán sin duda las TICs. En todo este proceso, las regiones metropolitanas en Europa se erigen como motores del crecimiento, donde los límites administrativos son superados, en un territorio cada vez más extendido y donde los gobiernos locales tienen que organizarse mediante un proceso de cooperación en la provisión de servicios que ayuden a evitar los desequilibrios territoriales. El fenómeno de la dispersión urbana en desarrollos de baja densidad, los centros comerciales periféricos, la expulsión hacia la periferia de las actividades de menor valor añadido y la concentración de funciones directivas en el centro, conducen a una fragmentación del territorio en islas dependientes del automóvil y a procesos de exclusión social por la huida de las rentas altas y la expulsión de las rentas bajas de los centros urbanos. Se crean fragmentos monofuncionales y discontinuos, apoyados en las autovías, lugares carentes de identidad y generadores de despilfarro de recursos y una falta de sostenibilidad ambiental, económica y social. El estudio de la cultura de la planificación en Europa ayuda a comprender los diferentes enfoques en la ordenación del territorio y el proceso de convergencia entre las diferentes regiones. Los documentos de la UE se basan en la necesidad de la competitividad para el crecimiento europeo y la cohesión social y en relación al territorio en los desarrollos policéntricos, la resolución del dualismo campo-ciudad, el acceso equilibrado a las infraestructuras, la gestión prudente de la naturaleza, el patrimonio y el fomento de la identidad. Se proponen dos niveles de estudio uno actual, los últimos planes de Londres y Paris y el otro la evolución de las tentativas de planes en la Región madrileña siempre en relación a los paradigmas emergentes señalados y su reflejo en los documentos. El Plan de Londres es estratégico, con una visión a largo plazo, donde se confiere un gran interés al proceso, al papel del alcalde como líder y su adaptación a las circunstancias cambiantes, sujeto a las incertidumbres de una ciudad global. El desarrollo del mismo se concibe a través de la colaboración y cooperación entre las administraciones y actores. La estructura del documento es flexible, establece orientaciones y guías indicativas, para la redacción de los planes locales, no siendo las mismas vinculantes y con escasa representación grafica. El Plan de París es más un plan físico, similar al de otros centros europeos, trabaja sobre los sectores y sobre los territorios, con información extensa, con características de “Plan Latino” por la fuerza de la expresión gráfica, pero al mismo tiempo contiene una visión estratégica. Es vinculante en sus determinaciones y normativas, se plantea fomentar, pero también prohibir. Ambos planes tratan la competitividad internacional de sus centros urbanos, la igualdad social, la inclusión de todos los grupos sociales y la vivienda como una cuestión de dignidad humana. Londres plantea la gobernanza como cooperación entre sector público-privado y la necesaria cooperación con las regiones limítrofes, en París las relaciones están más institucionalizadas resaltando la colaboración vertical entre administraciones. Ambos plantean la densificación de nodos servidos por transporte público, modos blandos y el uso los TODs y la preservación de la infraestructura verde jerarquizada, la potenciación de la red azul y la mejora del paisaje de las periferias. En las “tentativas” de planes territoriales de Madrid se constata que estuvieron sujetas a los ciclos económicos. El primer Documento las DOT del año 1984, no planteaba crecimiento, ni económico ni demográfico, a medio plazo y por ello no proponía una modificación del modelo radio concéntrico. Se trataba de un Plan rígido volcado en la recuperación del medio rural, de la ciudad, el dimensionamiento de los crecimientos en función de las dotaciones e infraestructuras existentes. Aboga por la intervención de la administración pública y la promoción del pequeño comercio. Destaca el desequilibrio social en función de la renta, la marginación de determinados grupos sociales, el desequilibrio residencia/empleo y la excesiva densidad. Incide en la necesidad de viviendas para los más desfavorecidos mediante el alquiler, la promoción suelo público y la promoción del ferrocarril para dar accesibilidad al espacio central. Aboga por el equipamiento de proximidad y de pequeño tamaño, el tratamiento paisajístico de los límites urbanos de los núcleos y el control de las actividades ilegales señalando orientaciones para el planeamiento urbano. Las Estrategias (1989) contienen una visión: la modificación del modelo territorial, mediante la intervención pública a través de proyectos. Plantea la reestructuración económica del territorio, la reconversión del aparato productivo, la deslocalización de actividades de escaso valor añadido y una mayor ubicuidad de la actividad económica. Incide en la difusión de la centralidad hacia el territorio del sur, equilibrándolo con el norte, tratando de recomponer empleo y residencia, integrando al desarrollo económico las periferias entre sí y con el centro. Las actuaciones de transporte consolidarían las actuaciones, modificando el modelo radio concéntrico facilitando la movilidad mediante la red de cercanías y la intermodalidad. El plan se basaba en el liderazgo del Consejero, no integrando sectores como el medio ambiente, ni estableciendo un documento de seguimiento de las actuaciones que evaluara los efectos de las políticas y su aportación al equilibrio territorial, a través de los proyectos realizados. El Documento Preparatorio de las Bases (1995), es más de un compendio o plan de planes, recoge análisis y propuestas de los documentos anteriores y de planes sectoriales de otros departamentos. Presenta una doble estructura: un plan físico integrador clásico, que abarca los sectores y territorios, y recoge las Estrategias previas añadiendo puntos fuertes, como el malestar urbano y la rehabilitación el centro. Plantea la consecución del equilibrio ambiental mediante el crecimiento de las ciudades existentes, la vertebración territorial basada en la movilidad y en la potenciación de nuevas centralidades, la mejora de la habitabilidad y rehabilitación integral del Centro Urbano de Madrid, y la modernización del tejido productivo existente. No existe una idea-fuerza que aglutine todo el documento, parte del reconocimiento de un modelo existente concentrado y congestivo, un centro urbano dual y dos periferias al este y sur con un declive urbano y obsolescencia productiva y al oeste y norte con una dispersión que amenaza al equilibrio medioambiental. Señala como aspectos relevantes, la creciente polarización y segregación social, la deslocalización industrial, la aparición de las actividades de servicios a las empresas instaladas en las áreas metropolitanas, y la dispersión de las actividades económicas en el territorio por la banalización del uso del automóvil. Se plantea el reto de hacer ciudad de la extensión suburbana y su conexión con el sistema metropolitano, mediante una red de ciudades integrada y complementaria, en búsqueda de un mayor equilibrio y solidaridad territorial. Las Bases del PRET (1997) tenían como propósito iniciar el proceso de concertación en que debe basarse la elaboración del Plan. Parte de la ciudad mediterránea compacta, y diversa, y de la necesidad de que las actividades económicas, los servicios y la residencia estén en proximidad, resolviéndolo mediante una potente red de transporte público que permitiese una accesibilidad integrada al territorio. El flujo de residencia hacia la periferia, con un modelo ajeno de vivienda unifamiliar y la concentración del empleo en el centro producen desequilibrio territorial. Madrid manifiesta siempre apostó por la densificación del espacio central urbanizado, produciendo su congestión, frente al desarrollo de nuevos suelos que permitieran su expansión territorial. Precisa que es necesario preservar los valores de centralidad de Madrid, como generador de riqueza, canalizando toda aquella demanda de centralidad, hacia espacios más periféricos. El problema de la vivienda no lo ve solo como social, sino como económico, debido a la pérdida de empleos que supone su paralización. Observa ya los crecimientos residenciales en el borde de la region por el menor valor del suelo. Plantea como la política de oferta ha dado lugar a un modelo de crecimiento fragmentado, desequilibrado, desestructurado, con fuertes déficits dotacionales y de equipamiento, que inciden en la segregación espacial de las rentas, agravando el proceso de falta de identidad morfológica y de desarraigo de los valores urbanos. El plan señalaba que la presión sobre el territorio creaba su densificación por las limitaciones de espacio, Incidía en limitar el peso de la intervención pública, no planteando propuestas de cooperación público-privado. La mayor incoherencia estriba en que los objetivos eran innovadores y coinciden en su mayoría con las propuestas estudiadas de Londres o Paris, pero se intentan implementar a través de un cambio hacia un modelo reticulado homogéneo, expansivo sobre el territorio, que supone un consumo de suelo y de infraestructuras para solucionar un problema inexistente, la gestión de la densidad. Durante las dos últimas décadas en ausencia de un plan regional, la postura neoliberal fue la de un exclusivo control de legalidad del planeamiento, los municipios entraron en un proceso de competencia para aprovechar las iniciales ventajas económicas de los crecimientos detectados, que proporcionaban una base económica “sólida” a unos municipios con escasos recursos en sus presupuestos municipales. La legislación se modifica a requerimiento de grupos interesados, no existiendo un marco estable. Se pierde la figura del plan no solo a nivel regional, si no en los sectores y el planeamiento municipal donde los municipios tiende a basarse en modificaciones puntuales con la subsiguiente pérdida del modelo urbanístico. La protección ambiental se estructura mediante un extenso nivel de figuras, con diversidad de competencias que impide su efectiva protección y control. Este proceso produce un despilfarro en la ocupación del suelo, apoyada en las infraestructuras viarias, y un crecimiento disperso y de baja densidad, cada vez más periférico, produciéndose una segmentación social por dualización del espacio en función de niveles de renta. Al amparo del boom inmobiliario, se produce una falta de política social de vivienda pública, más basada en la dinamización del mercado con producción de viviendas para rentas medias que en políticas de alquiler para determinados grupos concentrándose estas en los barrios desfavorecidos y en la periferia sur. Se produce un incremento de la vivienda unifamiliar, muchas veces amparada en políticas públicas, la misma se localiza en el oeste principalmente, en espacios de valor como el entorno del Guadarrama o con viviendas más baratas por la popularización de la tipología en la frontera de la Región. El territorio se especializa a modo de islas monofuncionales, las actividades financieras y de servicios avanzados a las empresas se localizan en el norte y oeste próximo, se pierde actividad industrial que se dispersa más al sur, muchas veces fuera de la región. Se incrementan los grandes centros comerciales colgados de las autovías y sin población en su entorno. Todo este proceso ha provocado una pérdida de utilización del transporte público y un aumento significativo del uso del vehículo privado. En la dos últimas décadas se ha producido en la región de Madrid desequilibrio territorial y segmentación social, falta de implicación de la sociedad en el territorio, dispersión del crecimiento y un incremento de los costes ambientales, sociales y económicos, situación, que solo, a través del uso racional del territorio se puede reconducir, apoyado en una planificación integrada sensible y participativa. ABSTRACT In Madrid the model of land occupation in the past two decades has been driven by market supply factors rather than the needs of the population. This results in a consumption of land and resources that leads to unsustainable overexploitation. Addressing this issue must be done through sensitive and participatory integrated planning. Global cities are experiencing rapid and intense change based on the emerging paradigms of globalization, governance, metropolization and the dispersion of activities in the territory. Through this context, a closer look will be taken at the London and Paris plans as well as the tentative plans of Madrid. Globalization causes the loss of state sovereignty and the competitiveness among global cities in Europe; London, Paris and Madrid. These are centres of power, concentration and growth where the duality of space is produced, and where inequality plays a part in urban restructuration. There are concentrated areas of poverty versus areas with a new emerging class where the services sector and information technologies are dominant. The introduction of ICTs contributes to a more homogeneous flow of information leading, us to the concept of governance. Against neoliberal urban development based on free market regulations and efficiency criteria as established by the “New Public Management”, emerge new ways where society administers itself through voluntary and responsible actions to promote collective interests by recognizing their own identity. A new model of public-private partnerships surfaces that is based on mutual trust, transparency, information and a stable regulatory framework in light of territorial exploitation by the “extractive society” that generates corruption. Throughout this process, European metropolitan regions become motors of growth where administrative boundaries are overcome in an ever expanding territory where government is organized through cooperative processes to provide services that protect against regional imbalances. Urban sprawl or low-density development as seen in peripheral shopping centres, the off-shoring of low added-value activities to the periphery, and the concentration of business and top management functions in the centre, leads to a fragmentation of the territory in automobile dependent islands and a process of social exclusion brought on by the disappearance of high incomes. Another effect is the elimination of low income populations from urban centres. In consequence, discontinuous expansions and mono-functional places that lack identity materialize supported by a highway network and high resource consumption. Studying the culture of urban planning in Europe provides better insight into different approaches to spatial planning and the process of convergence between different regions. EU documents are based on the need of competitiveness for European growth and social cohesion. In relation to polycentric development territory they are based on a necessity to solve the dualism between field and city, balanced access to infrastructures, prudent management of nature and solidifying heritage and identity Two levels of study unfold, the first being the current plans of London and Île-de-France and the second being the evolution of tentative plans for the Madrid region as related to emerging paradigms and how this is reflected in documents. The London Plan is strategic with a long-term vision that focuses on operation, the role of the mayor as a pivotal leader, and the adaptability to changing circumstances brought on by the uncertainties of a global city. Its development is conceived through collaboration and cooperation between governments and stakeholders. The document structure is flexible, providing guidance and indicative guidelines on how to draft local plans so they are not binding, and it contains scarce graphic representation. The Plan of Paris takes on a more physical form and is similar to plans of other European centres. It emphasizes sectors and territories, using extensive information, and is more characteristic of a “Latin Plan” as seen in its detailed graphic expression. However, it also contains a strategic vision. Binding in its determinations and policy, it proposes advancement but also prohibition. Both plans address the international competitiveness of urban centres, social equality, inclusion of all social groups and housing as issues of human dignity. London raises governance and cooperation between public and private sector and the need for cooperation with neighbouring regions. In Paris, the relations are more institutionalized highlighting vertical collaboration between administrations. Both propose nodes of densification served by public transportation, soft modes and the use of TOD, the preservation of a hierarchical green infrastructure, and enhancing the landscape in urban peripheries. The tentative territorial plans for the Madrid region provide evidence that they were subject to economic cycles. The first document of master guidelines (1984) does not address either economic or demographic growth in the mid term and therefore does not propose the modification of the radio-concentric model. It is a rigid plan focused on rural and urban recovery and the dimensioning of growth that depends on endowments and infrastructures. It advocates government intervention and promotes small business. The plan emphasizes social imbalance in terms of income, marginalization of certain social groups, the imbalance of residence/employment and excessive density. It stresses the need for social rent housing for the underprivileged, promotes public land, and the supports rail accessibility to the central area. It backs facilities of proximity and small size, enhancing the landscaping of city borders, controlling illegal activities and draws out guidelines for urban planning. The strategies (1989) contain a vision: Changing the territorial model through public intervention by means of projects. They bring to light economic restructuring of territory, the reconversion of the productive apparatus, relocation of low value-added activities, and greater ubiquity of economic activity. They also propose the diffusion of centrality towards southern territories, balancing it with the north in an attempt to reset employment and residence that integrates peripheral economic development both in the periphery and the centre. Transport would consolidate the project, changing the radius-concentric model and facilitating mobility through a commuter and inter-modality network. The plan derives itself from the leadership of the minister and does not integrate sectors such as environment. It also does not incorporate the existence of a written document that monitors performance to evaluate the effects of policies and their contribution to the territorial balance. The Preparatory Document of the Bases, (1995) is more a compendium, or plan of plans, that compiles analysis and proposals from previous documents and sectorial plans from other departments. It has a dual structure: An integrating physical plan covering the sectors and territories that includes the previous strategies while adding some strengths. One such point is the urban discomfort and the rehabilitation of the centre. It also poses the achievement of environmental balance through the growth of existing cities, the territorial linking based on mobility, strengthening new centres, improving the liveability and comprehensive rehabilitation of downtown Madrid, and the modernization of the existing production network. There is no one powerful idea that binds this document. This is due to the recognition of an existing concentrate and congestive model, a dual urban centre, two eastern and southern suburbs suffering from urban decay, and an obsolescent productive north and west whose dispersion threatens the environmental balance. Relevant aspects the document highlights are increasing polarization and social segregation, industrial relocation, the emergence of service activities to centralized companies in metropolitan areas and the dispersion of economic activities in the territory by the trivialization of car use. It proposes making the city from the suburban sprawl and its connection to the metropolitan system through a network of integrated and complementary cities in search of a better balance and territorial solidarity. The Bases of PRET (1997) aims to start the consultation process that must underpin the development of the plan. It stems from a compact and diverse Mediterranean city along with the need for economic activities, services and residences that are close. To resolve the issue, it presents a powerful network of public transport that allows integrated accessibility to the territory. The flow of residence to the periphery based on a foreign model of detached housing and an employment concentration in the centre produces territorial imbalance. Madrid always opted for the densification of the central space, producing its congestion, against the development of new land that would allow its territorial expansion. The document states that the necessity to preserve the values of the housing problem is not only viewed as social, but also economic due to the loss of jobs resulting from their paralysis. It notes the residential growth in the regional border due to the low price of land and argues that the policy of supply has led to a fragmented model of growth that is unbalanced, unstructured, with strong infrastructure and facility deficits that affect the spatial segregation of income and aggravate the lack of morphological identity, uprooting urban values. The pressure on the territory caused its densification due to space limitation; the proposed grid model causes land consumption and infrastructure to solve a non-problem, density. Focusing on limiting the weight of public intervention, it does not raise proposals for public-private cooperation. The biggest discrepancy is that the targets were innovative and mostly align with the proposals in London and Paris. However, it proposes to be implemented through a shift towards a uniform gridded model that is expansive over territory. During the last two decades, due to the absence of a regional plan, a neoliberal stance held exclusive control of the legality of urban planning. The municipalities entered a competition process to take advantage of initial economic benefits of such growth. This provided a “solid” economic base for some municipalities with limited resources in their municipal budgets. The law was amended without a legal stable framework at the request of stakeholders. The character of the plan is lost not only regionally, but also in the sectors and municipal planning. This tends to be based on specific changes with the loss of an urban model. Environmental protection is organized through an extensive number of protection figures with diverse competencies that prevent its effective protection. This process squanders the use of the land, backed by increasing road infrastructure, dispersed occupations with low-density growth causing a social segmentation due to space duality based on income levels. During the housing boom, there is a reduction in social public housing policy mostly due to a boost in the market of housing production for average incomes than in rental policies for needy social groups that focus on disadvantaged neighbourhoods and southern suburbs. As a result, there is an increase in single-family housing, often protected by public policy. This is located primarily in the west in areas of high environmental value such as Guadarrama. There is also cheaper housing due to the popularization of typology in the border region. There, territory works as a mono-functional islands. Financial activities and advanced services for companies are located to the north and west where industrial activity is lost as it migrates south, often outside the region. The number of large shopping centres hanging off the highway infrastructure with little to no surrounding population increases. This process leads to the loss of dependency on public transport and a significant increase in the use of private vehicles. The absence of regional planning has produced more imbalance, more social segmentation, more dispersed growth and a lot of environmental, social and economic costs that can only be redirected through rational territorial.

Governance Structure Choices in Supply Chain Management Evidence from Spanish and Chinese Pork Chain Cases

The author participated in the 6 th EU Framework Project ―Q-pork Chains (FP6-036245-2)‖ from 2007 to 2009. With understanding of work reports from China and other countries, it is found that compared with other countries, China has great problems in pork quality and safety. By comparing the pork chain management between China and Spain, It is found that the difference in governance structure is one of the main differences in pork chain management between Spain and China. In China, spot-market relationship still dominates governance structure of pork chain, especially between the numerous house-hold pig holders and the great number of small slaughters. While in Spain, chain agents commonly apply cooperatives or integrations to cooperate. It also has been proven by recent studies, that in quality management at the chain level that supply chain integration has a direct effect on quality management practices (Han, 2010). Therefore, the author started to investigate the governance structure choices in supply chain management. And it has been set as the first research objective, which is to explain the governance structure choices process and the influencing factors in supply chain management, analyzing the pork chains cases in Spain and in China. During the further investigation, the author noticed the international trade of pork between Spain and China is not smooth since the signature of bi-lateral agreement on pork trade in 2007. Thus, another objective of the research is to find and solve the problems exist in the international pork chain between Spain and China. For the first objective, to explain the governance structure choices in supply chain management, the thesis conducts research in three main sections. 10 First of all, the thesis gives a literature overview in chapter two on Supply Chain Management (SCM), agri-food chain management and pork chain management. It concludes that SCM is a systems approach to view the supply chains as a whole, and to manage the total flow of goods inventory from the supplier to the ultimate customer. It includes the bi-directional flow of products (materials and services) and information, and the associated managerial and operational activities. And it also is a customer focus to create unique and individual source of customer value with an appropriate use of resources, leading to customer satisfaction and building competitive chain advantages. Agri-food chain management and pork chain management are applications of SCM in agri-food sector and pork sector respectively. Then, the research gives a comparative study in chapter three in the pork chain and pork chain management between Spain and China. Many differences are found, while the main difference is governance structure in pork chain management. Furthermore, the author gives an empirical study on governance structure choice in chapter five. It is concluded that governance structure of supply chain consists of a collection of rules/institutions/constraints structuring the transactions between the various stakeholders. Based on the overview on literatures closely related with governance structure, such as transaction cost economics, transaction value analysis and resource-based view theories, seven hypotheses are proposed, which are: Hypothesis 1: Transaction cost has positive relationship with governance structure choice Hypothesis 2: Uncertainty has positive relationship with transaction cost; higher uncertainty exerts high transaction cost Hypothesis 3: The relationship between asset specificity and transaction cost is positive Hypothesis 4: Collaboration advantages and governance structure choice have positive relationship11 Hypothesis 5: Willingness to collaborate has positive relationship with collaboration advantages Hypothesis 6: Capability to collaborate has positive relationship with collaboration advantages Hypothesis 7: Uncertainty has negative effect on collaboration advantages It is noted that as transaction cost value is negative, the transaction cost mentioned in the hypotheses is its absolute value. To test the seven hypotheses, Structural Equation Model (SEM) is applied and data collected from 350 pork slaughtering and processing companies in Jiangsu, Shandong and Henan Provinces in China is used. Based on the empirical SEM model and its results, the seven hypotheses are proved. The author generates several conclusions accordingly. It is found that the governance structure choice of the chain not only depends on transaction cost, it also depends on collaboration advantages. Exchange partners establish more stable and more intense relationship to reduce transaction cost and to maximize collaboration advantages. ―Collaboration advantages‖ in this thesis is defined as the joint value achieved through transaction (mutual activities) of agents in supply chains. This value forms as improvements, mainly in mutual logistics systems, cash response, information exchange, technological improvements and innovative improvements and quality management improvements, etc. Governance structure choice is jointly decided by transaction cost and collaboration advantages. Chain agents take different governance structures to coordinate in order to decrease their transaction cost and to increase their collaboration advantages. In China´s pork chain case, spot market relationship dominates the governance structure among the numerous backyard pig farmer and small family slaughterhouse 12 as they are connected by acquaintance relationship and the transaction cost in turn is low. Their relationship is reliable as they know each other in the neighborhood; as a result, spot market relationship is suitable for their exchange. However, the transaction between large-scale slaughtering and processing industries and small-scale pig producers is becoming difficult. The information hold back behavior and hold-up behavior of small-scale pig producers increase transaction cost between them and large-scale slaughtering and processing industries. Thus, through the more intense and stable relationship between processing industries and pig producers, processing industries reduce the transaction cost and improve the collaboration advantages with their chain partners, in which quality and safety collaboration advantages be increased, meaning that processing industries are able to provide consumers products with better quality and higher safety. It is also drawn that transaction cost is influenced mainly by uncertainty and asset specificity, which is in line with new institutional economics theories developed by Williamson O. E. In China´s pork chain case, behavioral uncertainty is created by the hold-up behaviors of great numbers of small pig producers, while big slaughtering and processing industries having strong asset specificity. On the other hand, ―collaboration advantages‖ is influenced by chain agents´ willingness to collaborate and chain agents´ capabilities to cooperate. With the fast growth of big scale slaughtering and processing industries, they are more willing to know and make effort to cooperate with their chain members, and they are more capable to create joint value together with other chain agents. Therefore, they are now the main chain agents who drive more intense and stable governance structure in China‘s pork chain. For the other objective, to find and solve the problems in the international pork chain between Spain and China, the research gives an analysis in chapter four on the 13 international pork chain. This study gives explanations why the international trade of pork between Spain and China is not sufficient from the chain perspective. It is found that the first obstacle is the high quality and safety requirement set by Chinese government. It makes the Spanish companies difficult to get authorities to export. Other aspects, such as Spanish pork is not competitive in price compared with other countries such as Denmark, United States, Canada, etc., Chinese consumers do not have sufficient information on Spanish pork products, are also important reasons that Spain does not export great quantity of pork products to China. It is concluded that China´s government has too much concern on the quality and safety requirements to Spanish pork products, which makes trade difficult to complete. The two countries need to establish a more stable and intense trade relationship. They also should make the information exchange sufficient and efficient and try to break trade barriers. Spanish companies should consider proper price strategies to win the Chinese pork market

Intelligent context-aware services based on internet of things architectures

La Internet de las Cosas (IoT), como parte de la Futura Internet, se ha convertido en la actualidad en uno de los principales temas de investigación; en parte gracias a la atención que la sociedad está poniendo en el desarrollo de determinado tipo de servicios (telemetría, generación inteligente de energía, telesanidad, etc.) y por las recientes previsiones económicas que sitúan a algunos actores, como los operadores de telecomunicaciones (que se encuentran desesperadamente buscando nuevas oportunidades), al frente empujando algunas tecnologías interrelacionadas como las comunicaciones Máquina a Máquina (M2M). En este contexto, un importante número de actividades de investigación a nivel mundial se están realizando en distintas facetas: comunicaciones de redes de sensores, procesado de información, almacenamiento de grandes cantidades de datos (big--‐data), semántica, arquitecturas de servicio, etc. Todas ellas, de forma independiente, están llegando a un nivel de madurez que permiten vislumbrar la realización de la Internet de las Cosas más que como un sueño, como una realidad tangible. Sin embargo, los servicios anteriormente mencionados no pueden esperar a desarrollarse hasta que las actividades de investigación obtengan soluciones holísticas completas. Es importante proporcionar resultados intermedios que eviten soluciones verticales realizadas para desarrollos particulares. En este trabajo, nos hemos focalizado en la creación de una plataforma de servicios que pretende facilitar, por una parte la integración de redes de sensores y actuadores heterogéneas y geográficamente distribuidas, y por otra lado el desarrollo de servicios horizontales utilizando dichas redes y la información que proporcionan. Este habilitador se utilizará para el desarrollo de servicios y para la experimentación en la Internet de las Cosas. Previo a la definición de la plataforma, se ha realizado un importante estudio focalizando no sólo trabajos y proyectos de investigación, sino también actividades de estandarización. Los resultados se pueden resumir en las siguientes aseveraciones: a) Los modelos de datos definidos por el grupo “Sensor Web Enablement” (SWE™) del “Open Geospatial Consortium (OGC®)” representan hoy en día la solución más completa para describir las redes de sensores y actuadores así como las observaciones. b) Las interfaces OGC, a pesar de las limitaciones que requieren cambios y extensiones, podrían ser utilizadas como las bases para acceder a sensores y datos. c) Las redes de nueva generación (NGN) ofrecen un buen sustrato que facilita la integración de redes de sensores y el desarrollo de servicios. En consecuencia, una nueva plataforma de Servicios, llamada Ubiquitous Sensor Networks (USN), se ha definido en esta Tesis tratando de contribuir a rellenar los huecos previamente mencionados. Los puntos más destacados de la plataforma USN son: a) Desde un punto de vista arquitectónico, sigue una aproximación de dos niveles (Habilitador y Gateway) similar a otros habilitadores que utilizan las NGN (como el OMA Presence). b) Los modelos de datos están basado en los estándares del OGC SWE. iv c) Está integrado en las NGN pero puede ser utilizado sin ellas utilizando infraestructuras IP abiertas. d) Las principales funciones son: Descubrimiento de sensores, Almacenamiento de observaciones, Publicacion--‐subscripcion--‐notificación, ejecución remota homogénea, seguridad, gestión de diccionarios de datos, facilidades de monitorización, utilidades de conversión de protocolos, interacciones síncronas y asíncronas, soporte para el “streaming” y arbitrado básico de recursos. Para demostrar las funcionalidades que la Plataforma USN propuesta pueden ofrecer a los futuros escenarios de la Internet de las Cosas, se presentan resultados experimentales de tres pruebas de concepto (telemetría, “Smart Places” y monitorización medioambiental) reales a pequeña escala y un estudio sobre semántica (sistema de información vehicular). Además, se está utilizando actualmente como Habilitador para desarrollar tanto experimentación como servicios reales en el proyecto Europeo SmartSantander (que aspira a integrar alrededor de 20.000 dispositivos IoT). v Abstract Internet of Things, as part of the Future Internet, has become one of the main research topics nowadays; in part thanks to the pressure the society is putting on the development of a particular kind of services (Smart metering, Smart Grids, eHealth, etc.), and by the recent business forecasts that situate some players, like Telecom Operators (which are desperately seeking for new opportunities), at the forefront pushing for some interrelated technologies like Machine--‐to--‐Machine (M2M) communications. Under this context, an important number of research activities are currently taking place worldwide at different levels: sensor network communications, information processing, big--‐ data storage, semantics, service level architectures, etc. All of them, isolated, are arriving to a level of maturity that envision the achievement of Internet of Things (IoT) more than a dream, a tangible goal. However, the aforementioned services cannot wait to be developed until the holistic research actions bring complete solutions. It is important to come out with intermediate results that avoid vertical solutions tailored for particular deployments. In the present work, we focus on the creation of a Service--‐level platform intended to facilitate, from one side the integration of heterogeneous and geographically disperse Sensors and Actuator Networks (SANs), and from the other the development of horizontal services using them and the information they provide. This enabler will be used for horizontal service development and for IoT experimentation. Prior to the definition of the platform, we have realized an important study targeting not just research works and projects, but also standardization topics. The results can be summarized in the following assertions: a) Open Geospatial Consortium (OGC®) Sensor Web Enablement (SWE™) data models today represent the most complete solution to describe SANs and observations. b) OGC interfaces, despite the limitations that require changes and extensions, could be used as the bases for accessing sensors and data. c) Next Generation Networks (NGN) offer a good substrate that facilitates the integration of SANs and the development of services. Consequently a new Service Layer platform, called Ubiquitous Sensor Networks (USN), has been defined in this Thesis trying to contribute to fill in the previous gaps. The main highlights of the proposed USN Platform are: a) From an architectural point of view, it follows a two--‐layer approach (Enabler and Gateway) similar to other enablers that run on top of NGN (like the OMA Presence). b) Data models and interfaces are based on the OGC SWE standards. c) It is integrated in NGN but it can be used without it over open IP infrastructures. d) Main functions are: Sensor Discovery, Observation Storage, Publish--‐Subscribe--‐Notify, homogeneous remote execution, security, data dictionaries handling, monitoring facilities, authorization support, protocol conversion utilities, synchronous and asynchronous interactions, streaming support and basic resource arbitration. vi In order to demonstrate the functionalities that the proposed USN Platform can offer to future IoT scenarios, some experimental results have been addressed in three real--‐life small--‐scale proofs--‐of concepts (Smart Metering, Smart Places and Environmental monitoring) and a study for semantics (in--‐vehicle information system). Furthermore we also present the current use of the proposed USN Platform as an Enabler to develop experimentation and real services in the SmartSantander EU project (that aims at integrating around 20.000 IoT devices).

Training organization of a middle-size company engaged in information technology services: theory and practice

In order to establish an active internal know-how -reserve~ in an information processing and engineering services . company, a training architecture tailored to the company as an whole must be defined. When a company' s earnings come from . advisory services dynamically structured i.n the form of projects, as is the case at hand, difficulties arise that must be taken into account in the architectural design. The first difficulties are of a psychological nature and the design method proposed here begjns wi th the definition of the highest training metasystem, which is aimed at making adjustments for the variety of perceptions of the company's human components, before the architecture can be designed. This approach may be considered as an application of the cybernetic Law of Requisita Variety (Ashby) and of the Principle of Conceptual Integrity (Brooks) . Also included is a description of sorne of the results of the first steps of metasystems at the level of company organization.

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
