Cambios de la identidad social en organizaciones en red

Las organizaciones están viviendo cambios estratégicos, culturales y organizativos para adaptarse a la sociedad de la información. La incorporación de las Tecnologías de la Información y la Comunicación (TIC), facilita los esquemas de trabajo en red de los y las profesionales y la virtualización de las organizaciones. En este nuevo contexto, el sistema de significados cambia, y la identidad social de los trabajadores se ve afectada. Este trabajo explora cómo se comporta la identidad social y cuál es su relación con la necesidad de afiliación, estudiando un grupo de 205 profesionales con distintas características, lo que ha permitido dividirlos en profesionales red y profesionales no red. A su vez, estos profesionales pertenecían a organizaciones que, en función de ciertas características, se han categorizado en más o menos virtuales. Los resultados principales del trabajo son el establecimiento de un método de análisis en organizaciones red y la confirmación de que en la transformación de una organización hacia modelos virtuales, la identidad social se debilita para profesionales con alta necesidad de afiliación. Organizations are experiencing strategic, cultural and organizational changes in order to adapt themselves to the Information Society. Incorporating Information and Communication Technologies (ICTs) allow for network schemes of work for employees (including telecommuting) and staff virtualization. In this new context, systems of meaning change and the social identity of the staff is affected. This paper analyses how social identity evolves and how it is related to affiliation needs by studying a group of 205 professionals with different characteristics, divided into network and non-network professionals. In turn, these professionals belonged to organizations, which depending on certain characteristics, have been categorized as more or less virtual. Two main research results emerge. The first is an analytical methodology for networked organizations. The second is the confirmation that social identity weakens for professionals with high affiliation needs when virtualization occurs in an organization.

Mandate M 376: new software accessibility requirements

Software needs to be accessible for persons with disabilities and there are several guidelines to assist developers in building more accessible software. Regulation activities are beginning to make the accessibility of software a mandatory requirement in some countries. One such activity is the European Mandate M 376, which will result in a European standard (EN 301 549) defining functional accessibility requirements for information and communication technology products and services. This paper provides an overview of Mandate M 376 and EN 301 549, and describes the requirements for software accessibility defined in EN 301 549, according to a feature-based approach

The University in the Cloud Computing.

With the advancement of Information and Communication Technology ICT which favors increasingly fast, easy, and accessible communication for all and which can reach large groups of people, there have been changes, in recent years in our society that have modified the way we interact, communicate and transmit information. Access to this, it is possible, not only through computers situated in a fixed location, but new mobile devices make it available, wherever the user happens to be located. Now, information "travels" with the user. These forms of communication, transmission and access to information, have also affected the way to conceive and manage business. To these new forms of business that the Internet has brought, is now added the concept of companies in the Cloud Computing ClC. The ClC technology is based on the supply and consumption of services on demand and pay per use, and it gives a 180 degree turn to the business management concept. Small and large businesses may use the latest developments in ICT, to manage their organizations without the need for expensive investments in them. This will enable enterprises to focus more specifically within the scope of their business, leaving the ICT control to the experts. We believe that education can also and should benefit from these new philosophies. ?Due to the global economic crisis in general and each country in particular, economic cutbacks have come to most universities. These are seen in the need to raise tuition rates, which makes increasingly fewer students have the opportunity to pursue higher education?. In this paper we propose using ClC technologies in universities and we make a dissertation on the advantages that it can provide to both: universities and students. For the universities, we expose two focuses, one: ?to reorganize university ICT structures with the ClC philosophy? and the other one, ?to extend the offer of the university education with education on demand?. Regarding the former we propose to use public or private Clouds, to reuse resources across the education community, to save costs on infrastructure investment, in upgrades and in maintenance of ICT, and paying only for what you use and with the ability to scale according to needs. Regarding the latter, we propose an educational model in the ClC, to increase the current university offerings, using educational units in the form of low-cost services and where students pay only for the units consumed on demand. For the students, they could study at any university in the world (virtually), from anywhere, without travel costs: money and time, and what is most important paying only for what they consume. We think that this proposal of education on demand may represent a great change in the current educational model, because strict registration deadlines disappear, and also the problem of economically disadvantaged students, who will not have to raise large amounts of money for an annual tuition. Also it will decrease the problem of loss of the money invested in an enrollment when the student dropout. In summary we think that this proposal is interesting for both, universities and students, we aim for "Higher education from anywhere, with access from any mobile device, at any time, without requiring large investments for students, and with reuse and optimization of resources by universities. Cost by consumption and consumption by service?. We argue for a Universal University "wisdom and knowledge accessible to all?

Proposal for the Conceptual Design of Aeronautical Final Assembly Lines Based on the Industrial Digital Mock-Up Concept

The design of a Final Assembly Line (FAL) is carry out in the product industrialization activity. The phase dealing with the definition of conceptual solutions is characterized by depending heavily on the personnel experience and being time-consuming. To enhance such process, it is proposed a development of a knowledge based software application to assist designers in the definition of scenarios and to generate conceptual FAL alternatives. Both the scenario and the generated FAL solution are part of the industrialization digital mock-up (IDMU). A commercial software application used in the aircraft programmes and supporting the IDMU concepts of: Product, Process and Resource; was selected to implement a software prototype. This communication presents the adopted methodological approach and the architecture of the developed application.

Collaborative Engineering Paradigm Applied to the Aerospace Industry

Airbus designs and industrializes aircrafts using Concurrent Engineering techniques since decades. The introduction of new PLM methods, procedures and tools, and the need to reduce time-to-market, led Airbus Military to pursue new working methods. Traditional Engineering works sequentially. Concurrent Engineering basically overlaps tasks between teams. Collaborative Engineering promotes teamwork to develop product, processes and resources from the conceptual phase to the start of the serial production. The CALIPSO-neo pilot project was launched to support the industrialization process of a medium size aerostructure. The aim is to implement the industrial Digital Mock-Up (iDMU) concept and its exploitation to create shop floor documentation. In a framework of a collaborative engineering strategy, the project is part of the efforts to deploy Digital Manufacturing as a key technology for the industrialization of aircraft assembly lines. This paper presents the context, the conceptual approach and the methodology adopted.

Propuesta de un sistema para detección precoz de trastornos del lenguaje en niños de 0 a 6 años

Las Tecnologías de la Información y las Comunicaciones han propiciado avances en el contexto de la salud tanto en la gestión efectiva de información socio‐sanitaria de forma electrónica, como en la provisión de servicios de e‐salud y telemedicina. Los antecedentes de investigación publicados en esta área corroboran este hecho presentando las mejoras experimentadas en la atención de la población y en la provisión de servicios sanitarios. La atención temprana, cuyos principios científicos se fundamentan en los campos de la pediatría, neurología, psicología, psiquiatría, pedagogía, fisiatría y lingüística, entre otros, tiene como finalidad ofrecer a los niños con déficit o con riesgo de padecerlos un conjunto de acciones optimizadoras y compensadoras, que faciliten su adecuada maduración en todos los ámbitos y que les permita alcanzar el máximo nivel de desarrollo personal y de integración social. La detección de posibles alteraciones en el desarrollo infantil es un aspecto clave de la atención temprana en la medida en que puede posibilitar la puesta en marcha de diversos mecanismos de actuación disponibles en las entidades implicadas, valiosos para la calidad de vida de la persona. Cuanto antes se realice la detección, existen mayores garantías de prevenir patologías añadidas, lograr mejoras funcionales y posibilitar un ajuste más adaptativo entre el niño y su entorno. El objetivo de la investigación presentada en esta tesis doctoral es analizar, diseñar, verificar y validar un sistema de información abierto, basado en conocimiento, que facilite efectivamente a los profesionales que trabajan con la población infantil entre 0 y 6 años la detección precoz de posibles trastornos del lenguaje. Desde el punto de vista metodológico, la Ingeniería del Conocimiento ofrece un marco conceptual sólido que permite desarrollar y validar Sistemas de Ayuda a la Toma de Decisiones distribuidos y escalables, capaces de ayudar al pediatra de Atención Primaria y al educador infantil en la detección precoz de posibles trastornos del lenguaje en niños. La evaluación del sistema se ha realizado de forma incremental mediante el diseño y validación de pruebas de campo experimentales consistentes en la evaluación de niños en dos escenarios distintos: la escuela infantil y el centro de atención temprana. Los experimentos realizados en poblaciones distintas con alrededor de 344 niños durante 2 años, han permitido contrastar la buena adecuación del sistema propuesto a las necesidades de detección de los profesionales que trabajan con niños entre 0 y 6 años. La tesis resultante ha permitido caracterizar el uso del sistema en entornos reales, conocer la aceptación entre los usuarios y su impacto en la provisión de un servicio de atención temprana como el descrito para el correcto seguimiento del desarrollo del lenguaje en los niños, además de proponer un nuevo modelo de atención y evaluación cooperativa que permita incrementar el conocimiento experimental existente al respecto. ABSTRACT The Information and Communication Technology have led to advances in the context of health both in the effective management of socio‐health information electronically, and in the provision of e‐health and telemedicine. The history of research published in this area confirm this fact by presenting the improvements in the care of the population and the provision of health services. Early attention, whose scientific principles are based on the fields of pediatrics, neurology, psychology, psychiatry, pedagogy, physical medicine and linguistics, among others, aims to provide children with deficits or risk of suffering a set of enhancer actions, which facilitate adequate maturation in all areas and allow them to achieve the highest level of personal development and social integration. The detection of possible changes in child development is a key aspect of early intervention to the extent that it can enable the implementation of different mechanisms of action available to the entities involved, valuable to the quality of life of the person. The earlier the detection is made, there are more guarantees added to prevent diseases, achieving functional improvements and enable a more adaptive fit between the child and his environment. The aim of the research presented is to analyze, design, verify and validate an open information system, based on knowledge, which effectively provide professionals working with the child population between 0 and 6 years, in processes of early detection of language disorders. From the methodological point of view, Knowledge Engineering provides a solid conceptual framework to develop and validate a distributed and scalable decision support systems aim to assist pediatricians and language therapists at early identification and referral of language disorder in childhood. The system evaluation was performed incrementally with the design and validation of consistent experimental field tests in the assessment of children in two different scenarios: the nursery and early intervention center. Experiments in different populations with about 344 children over 2 years, allowed to testing the adequacy of the proposed good detection needs of professionals working with children between 0 and 6 years old system. The resulting thesis has allowed to formalizing the system at real environments and to identifying the acceptance by users as well as its impact on the provision of an early intervention service, such as the one described for the proper monitoring of language development in children. In addition, it proposes a new model of care and cooperative evaluation that lets to increase the existing experimental knowledge about it.

Análisis de la cadena de valor, canales cortos de comercialización y horticultura multifuncional como opciones de puesta en valor: Caso de la Huerta de Aranjuez

La Vega de Aranjuez ha sido desde hace siglos conocida por la notoriedad de sus jardines y huertas históricas y también, en épocas más recientes, por ser la despensa de Madrid. A mediados del siglo XX, sin embargo, con las transformaciones que el sector agrario ha experimentado no sólo a nivel local, sino a escala global, empezó un proceso de declive que se ha acentuado en los últimos años. Paralelamente, en el año 2001, la Unesco declara el Paisaje Cultural de Aranjuez, como Patrimonio de la Humanidad con un valor universal excepcional. Parte de lo que sustenta este reconocimiento a nivel internacional radica en las peculiaridades del paisaje que conforma la actividad agraria. El cambio de orientación, eminentemente hortofrutícola hacia cultivos extensivos y superficies en barbecho, y la pérdida de importancia del sector, no han pasado desapercibidos para la administración local y han sido varios los intentos de recuperación y dinamización del sector en los últimos años. La investigación de la que es objeto esta Tesis Doctoral surgió por iniciativa del Ayuntamiento de Aranjuez, que en al año 2010 deseó conocer la situación del sector hortícola en el municipio, para lo cual, encargó un estudio a la UPM-ETSIA. Para conocer la realidad desde una perspectiva integral, se planteó abordar el análisis desde la perspectiva de Cadena de Valor. Las implicaciones de este concepto, su evolución y su papel como instrumento de análisis de la cadena alimentaria, han sido revisadas y presentadas en el epígrafe del Marco Conceptual. Por cadena de valor se entiende el conjunto de procesos desde el consumidor, a través de los proveedores que proporcionan productos, servicios e información que añaden valor hacia los clientes (Lambert & Cooper, 2000; Chen, 2004). Para el análisis de la situación del sector hortícola en Aranjuez, se procedió en varios pasos, los cuales constituyeron la primera fase de la investigación y contemplaron lo siguiente: 1. La identificación de los problemas y de las demandas de los actores de la cadena, realizando cortes transversales en el mercado a distintos niveles para conocer los puntos de vista de los operadores de la cadena (Gunasekaran & Patel ,2004; Rojas, 2009; Schiefer, 2007). Para ello se diseñaron cuestionarios y se dirigieron a representantes de cinco eslabones de la cadena presentes en el caso de estudio: Agricultores (15), Mayoristas (11), Detallistas (55), Consumidores (85) y Restaurantes (36), tanto en Aranjuez como en Madrid (un total de 202). 2. Análisis D.A.F.O de cada uno de los eslabones y de la cadena completa, como herramienta para identificar y sintetizar la problemática y las potencialidades del sector. 3. Análisis global de la Cadena de Valor mediante el Método de Organización Sectorial, según Briz, de Felipe y Briz (2010), el cual permite estudiar aspectos de la estructura, la conducta y el funcionamiento de la cadena. 4. Jornada de análisis por parte de un Panel de Expertos en la sede de la Fundación Foro Agrario, en la cual se presentaron las conclusiones del análisis de la cadena de valor y se plantearon estrategias para la dinamización del sector. Con los resultados del análisis en esta primera fase de la investigación, se obtuvo una panorámica de la cadena de valor. Algunos de los aspectos más destacados son los siguientes: • El eslabón productivo en Aranjuez está muy atomizado y trabaja por lo general de forma independiente. Cultiva hasta veinte productos hortícolas diferentes, entre los cuales los frutales están casi en desaparición y hay poca presencia de producto ecológico. Le preocupan los precios poco estables y bajos y por lo general no trabaja con contratos. •El eslabón mayorista prácticamente carece de presencia en Aranjuez y está representado en su mayoría por operadores de Mercamadrid, los cuales demandan mayores volúmenes y mejor normalización de los productos hortícolas procedentes de Aranjuez. • El eslabón detallista consultado es diverso (con representación de comercios minoristas, supermercados e hipermercados) y también demanda mayores volúmenes de producción y mejoras en la normalización. Un 80% conoce los productos de Aranjuez, especialmente el espárrago y la fresa-fresón citados en un 74% y 63% de los casos respectivamente. • En el eslabón de consumidores, el 79% de los encuestados da importancia a la procedencia de los productos hortícolas y un 82% conoce los productos de la Huerta de Aranjuez, siendo los más consumidos el espárrago y el fresón. Un 42% de los encuestados compra producto ecológico por razones de salud, sabor y buscando la ausencia de químicos. • El eslabón de restaurantes es un gran consumidor de hortalizas, la gran mayoría de los productos incluidos en el análisis se oferta en más del 75% de los casos. Las más presentes son tomate y espárrago. La fresa y el fresón (en un 83% de los casos), y el espárrago (72%) seguido de la alcachofa (44%) son los productos de Aranjuez que más se conocen en el conjunto de los restaurantes entrevistados. El 75% de los restaurantes prefiere el producto fresco frente al procesado o congelado. La mayoría de los restaurantes locales (92%) estaría dispuesto a incluir en su carta una diferenciación para los productos de Aranjuez. Sin embargo, en el resto de restaurantes el porcentaje es mucho menor (21%). Entre las conclusiones del análisis se evidenció que un 52% de las ventas de los agricultores se realizaba sin intermediarios y un 69% de los consumidores se manifestaba interesado en adquirir productos de Aranjuez directamente del campo a su casa. Se identificó de esta manera que el acortamiento de la cadena se está utilizando como una forma de crear valor. Para profundizar en este aspecto, se planteó una segunda fase en la investigación. Además de estudiar diversos aspectos de los canales cortos de comercialización, se planteó estudiar el enfoque multifuncional de la horticultura, como estrategia para poner en valor la Huerta ribereña. Para dar una coherencia con la fase anterior, el planteamiento se realizó también desde la perspectiva de la cadena de valor, orientando la consulta hacia el eslabón consumidor. De esta manera, se realizó una consulta mediante cuestionario a 221 consumidores sobre diferentes aspectos relativos a los Canales Cortos de Comercialización (CCC) y la Horticultura Multifuncional (HM)1, lo cual permitió realizar un análisis cuantitativo de diferentes variables. Para completar la visión integral de la cadena corta, se seleccionaron 6 proyectos significativos que son ejemplos de diversas tipologías de canales cortos de comercialización en Aranjuez y Madrid, como representantes del denominado eslabón de “Promotores de CCC” y se consultó también a la Asociación de Productores de la Huerta de Aranjuez, constituida formalmente en el año 2014, como representante del eslabón Productor. Para la obtención de información, la cual tiene un carácter cualitativo en el caso de estos dos eslabones de la cadena, se realizaron cuestionarios y Estudios de Caso de cada proyecto. Los cuestionarios de esta segunda fase de consulta a los eslabones de la cadena corta contuvieron cuestiones relativas a los canales cortos de comercialización, tanto a nivel general (concepto de canal corto, puntos fuertes y ventajas que aportan, dificultades para su desarrollo, factores clave para su éxito) como para el caso concreto de la Huerta de Aranjuez (perfil del consumidor, factores implicados en la compra de verduras, utilización de diversas modalidades de canal corto, relación con las tecnologías de la información y comunicación (TICs) y la producción ecológica o la importancia del factor confianza). También aspectos relacionados con la Horticultura Multifuncional, como son, la valoración de diferentes actividades o proyectos de carácter agro-turístico, educativo, social o terapéutico, o la percepción del consumidor de las actividades de huerta como fuente de bienestar y como agente satisfactor de diversas necesidades humanas. Para completar la visión sobre estos dos temas, CCC y HM, se realizó una consulta mediante cuestionario a Expertos en el campo de los canales cortos de comercialización, procedentes del ámbito académico, y a Profesionales en activo trabajando en proyectos de horticultura social y terapéutica. La información aportada, aunque tiene carácter cualitativo, complementa el estudio ofreciendo la perspectiva académica en el caso de los canales cortos y amplía la información sobre la horticultura multifuncional, tratando cuestiones relativas al desempeño profesional o a la formación existente en España en el campo de la horticultura social y terapéutica. Los resultados de esta segunda fase de la investigación, entre otras cuestiones, evidenciaron que: • Los canales cortos de comercialización implican mucho más que la simple reducción de intermediarios y comprenden una gran diversidad de tipologías. • Los casos estudiados, están enfocados en su mayoría al producto ecológico y su funcionamiento está muy fundamentado en el uso de TICs y en el factor confianza. • En relación a la compra de verduras en el ámbito de los canales cortos, son aspectos muy valorados por el consumidor la calidad del producto, la rapidez y frescura con la que llega del campo a la mesa y que el Producto sea recogido en su punto óptimo de maduración. • Las actividades en el ámbito de la horticultura multifuncional son valoradas positivamente por los consumidores, siendo las más puntuadas las de huerto educativo, huerto terapéutico, seguidas de visitas guiadas y degustaciones de productos de huerta en restaurantes. • Por lo general existe una valoración muy alta de la huerta como fuente de bienestar y de satisfacción de necesidades humanas básicas, especialmente las de una alimentación saludable y de conexión con la naturaleza. Para terminar esta síntesis de la investigación realizada, se presentan las principales conclusiones a nivel global de la Tesis, que son las siguientes: 1. La metodología de cadena de valor ha resultado adecuada para conocer la complejidad y el funcionamiento del sector hortícola arancetano desde una perspectiva integral. 2. La Huerta de Aranjuez cuenta con importantes fortalezas, sustentadas en la calidad de sus suelos y en la fama que mantienen sus productos, pero también debilidades. Esto supone poco volumen de producción, que dificulta la relación con mayoristas y grandes detallistas. 3. El acortamiento de la cadena, mediante canales cortos de comercialización se ha identificado como una forma de creación de valor en la cadena. Existen oportunidades de abastecimiento a consumidores de Madrid mediante canales cortos, sin embargo, las modalidades que requieren mayor organización o requisitos de producción ecológica todavía no están desarrolladas. 4. La producción ecológica podría ser una estrategia para crear valor pero todavía es un método de cultivo muy minoritario en la cadena productiva arancetana. 5. Las peculiaridades de la Huerta de Aranjuez propician la puesta en práctica del enfoque multifuncional de la horticultura como vía de desarrollo económico. Los resultados apuntan a una posible demanda de servicios que contemplen actividades de horticultura de carácter educativo, terapéutico y agro-turístico, conducidas por profesionales. Existe una percepción positiva sobre el potencial de la huerta como fuente de bienestar y de satisfacción de necesidades humanas básicas. 6. La puesta en marcha de proyectos empresariales en el ámbito de la horticultura social es una apuesta interesante para crear valor en la huerta que ha sido valorada positivamente por los eslabones de la cadena corta consultados. 7. El campo de la Horticultura Multifuncional que contempla aspectos educativos, sociales y terapéuticos conforma una disciplina con posibilidades de desarrollo que en la investigación se perciben como limitadas por la falta de profesionales y su acceso a una formación adecuada en España. El estudio de los Canales Cortos de Comercialización y de la Horticultura Multifuncional como vías de puesta en valor en el caso de la Huerta de Aranjuez ha tenido un carácter exploratorio y en gran parte cualitativo en esta Tesis Doctoral. Ambos conceptos han desvelado cierta complejidad y requieren de un mayor conocimiento en diversos aspectos para su puesta en práctica con éxito. Se abre, por tanto, un campo para futuras investigaciones que profundicen en estos ámbitos. ABSTRACT La Vega de Aranjuez has been known for centuries for the reputation of its orchards and historic gardens and, more recently, as the pantry of Madrid. However, in the mid-twentieth century, with the transformations in agriculture, not only locally, but globally, began a process of decline that has been accentuated in recent years. Meanwhile, in 2001, Unesco declared Aranjuez Cultural Landscape, as a World Heritage Site with outstanding universal value. Part of what underpins this international recognition lies in the peculiarities of the landscape created by farming. The shift, from an eminently horticultural vocation to extensive field crops and fallow surfaces, and the loss of importance of the sector, have not gone unnoticed for local authorities and have been several attempts at recovery and revitalization of the sector in recent years. The beginning of this research came at the initiative of the municipality of Aranjuez, which in 2010 wanted to know the situation of the horticultural sector, for which he commissioned a study by the UPM-ETSIA. To know reality from an integral perspective, it was proposed to approach the analysis from the perspective of value chain. The implications of this concept, its evolution and its role as an instrument of analysis of the food chain, have been reviewed and presented in Chapter 3.2. The value chain concept refers to all the processes from the consumer, through suppliers who provide products, services and information that add value to customers (Lambert & Cooper, 2000; Chen, 2004). For the analysis of the situation of the horticultural sector in Aranjuez, which constituted the first phase of research, it proceeded in several steps: 1. Identifying the problems and demands of the actors in the chain, making transverse cuts in the market at different levels to meet the views of the chain operators (Gunasekaran & Patel , 2004; Rojas, 2009; Schiefer, 2007). Questionnaires were designed for it and went to representatives of the five links in the chain: Farmers (15), Wholesalers (11), Retailers (55), Consumers (85) and Restaurants (36), both in Aranjuez and Madrid (a total of 202). 2. SWOT analysis of each chain actor and of the whole supply chain, as a tool to identify and synthesize the problems and potential of the sector. 3. Analysis of the whole supply chain by Industrial Organization Method according to Briz et al. (2010), which allows to study aspects of the structure, conduct and performance of the chain. 4. Analysis by a Panel of Experts at Foro Agrario Foundation headquarters, where the conclusions of the analysis were presented and strategies for the revitalization of the sector were raised. The results of the analysis in this first phase of the research, presented an overview of the value chain. Some of the highlights are: - The productive sector in Aranjuez is very fragmented and usually works independently. With a wide variety of horticultural products (up to 20), fruit crops almost disappearing and little presence of organic product. Is concerned about the unstable and low prices and usually does not work with contracts. - The wholesale sector with virtually no presence in Aranjuez is represented mostly by Mercamadrid operators, who demand higher volumes and better standardization of horticultural products from Aranjuez. - The retailer sector is diversified (with representation from retailers, supermarkets and hypermarkets) and also demand higher production volumes and improved standardization. 80% know the products of Aranjuez, especially asparagus and strawberry-strawberry cited by 74% and 63% of cases respectively. - Among the consumers, 79% give importance to the origin of horticultural products and 82% know the products from Aranjuez, the most consumed asparagus and strawberries. 42% buy organic products for health, taste and absence of chemicals. - Restaurants are big consumers of vegetables, most of the products included in the analysis is offered in over 75% of cases. The most: tomato and asparagus. Strawberry (83% of cases), and asparagus (72%) followed by the artichoke (44%) are the products of Aranjuez more known in all the surveyed restaurants. 75% of the restaurants prefer fresh product against processed or frozen. Most local restaurants (92%) would be willing to include in their menu a differentiation for products of Aranjuez. However, for those restaurants from Madrid the percentage is much lower (21%). Among the conclusions of the analysis it showed that 52% of sales were realized from farmers without intermediaries and 69% of consumers expressed interest in acquiring products directly from field to table. It has been identified that the shortening of the chain is being used as a way to create value. To deepen this aspect, a second phase investigation arose. Besides studying various aspects of the short supply chains, it was also proposed to study the functional approach of horticulture as a strategy to add value. To provide consistency with the previous phase, the focus was also conducted from the perspective of the value chain, directing the query to consumers. Thus, again it was used the questionnaire as a methodological tool, and 221 consumers were asked about different aspects of the Short Suppy Chains (SSC) and Multifunctional Horticulture (MH)2, which allowed a quantitative analysis of several variables. To complete the comprehensive view of the short chain, 6 significant projects were selected as examples of different types of short supply chains in Aranjuez and Madrid, representing "SSC Promoters" and also the “Asociación de Productores de la Huerta de Aranjuez”, formally constituted in 2014, was asked representing the productive sector. The Study Case and again the questionnaire were elected as methodological tools in a qualitative analysis. The questionnaires of this second phase of research contained short supply chain issues, as a general topic (short supply chain concept, strengths and advantages they bring difficulties for its development, key factors success) and also refered to the case of Aranjuez (consumer profile, factors involved in the purchase of vegetables, use of several types of short supply chains, relation with information and communication technologies (ICTs) and organic production or the importance of trust in short supply chains). It also contemplated aspects of multifunctional horticulture, such as the valuation of different activities (agro-tourism, educational, social or therapeutic horticulture) and consumer perception about horticultural activities as a source of welfare and satisfactor of human needs. To complete the vision of these two issues, SSC and MH, experts in the field of short supply chains and professionals working in the field of social and therapeutic horticulture were asked. The qualitative information provided, complements the study offering a new perspective in the value chain analysis, such as those relating to job performance, the difficulties encountered or training existing in our country in the field of social and therapeutic horticulture. The results of this second phase of research showed that: Short supply chains involve much more than simply reducing intermediaries and cover a wide range of types. The cases studied are mostly focused on ecological product and its operation is heavily based on the use of ICTs and the trust factor. In connection with the purchase of vegetables in the field of short supply chains, product quality, speed and freshness with which comes from the field to the table and products picked at its peak maturation, are aspects highly valued by the consumer. Activities in the field of multifunctional horticulture are positively valued by consumers, the most scored: the educational garden, therapeutic garden, followed by guided tours and tastings of vegetables from Aranjuez in restaurants. Horticultural activities were highly valuated as a source of welfare and satisfaction of human needs, especially those of healthy eating and connection with nature. To complete this summary, the main conclusions of the research are presented as follows: 1. The value chain approach has been adequate to meet the complexity and operation of the horticultural sector in Aranjuez from a holistic perspective. 2. La Huerta de Aranjuez has important strengths, underpinned by the quality of its soils and fame that keep their products, but also weaknesses. This implies low volume of production, which makes difficult the link with wholesalers and large retailers. 3. The shortening of the chain by short supply chains has been identified as a way of creating value in the chain. Opportunities exist to supply consumers from Madrid by short supply chains, however, methods that require greater organization or requirements of organic production are not yet developed. 4. Organic production could be a strategy to create value but is not generally being implemented in the production chain. 5. The peculiarity of the Huerta de Aranjuez favours the implementation of the multifunctional approach as a means of economic development. The results point to a possible demand for multifunctional horticulture that include educational, therapeutic and agro-tourism activities. There is a positive perception of the potential of horticultural activities as a source of welfare and satisfaction of basic human needs. 6. The implementation of business projects in the field of social horticulture are an interesting way to create value that has been highly valued in the short supply chain. 7. The field of Multifunctional Horticulture which includes educational, social and therapeutic aspects, forms a discipline with possibilities of development, which in research are seen as limited by the lack of professionals and access to adequate training in our country. The study of Short Supply Chains and Multifunctional Horticulture as strategies to create value in the case of the Huerta de Aranjuez has an exploratory character and largely qualitative in this research. Both concepts have revealed some complexity and require greater knowledge in various aspects for successful implementation. It opens therefore a field for future research to deepen in these areas.

Un estudio del adjetivo en un corpus de textos escritos en inglés y español pertenecientes al discurso de especialidad de las Tecnologías de la Información y las Comunicaciones

Esta investigación se enmarca dentro de los denominados lenguajes de especialidad que para esta tesis será el de las Tecnologías de la Información y la Comunicación (TIC). De todos los aspectos relacionados con el estudio de estos lenguajes que pudieran tener interés lingüístico ha primado el análisis del componente terminológico. Tradicionalmente la conceptualización de un campo del saber se representaba mayoritariamente a través del elemento nominal, así lo defiende la Teoría General de la Terminología (Wüster, 1968). Tanto la lexicología como la lexicografía han aportado importantes contribuciones a los estudios terminológicos para la identificación del componente léxico a través del cual se transmite la información especializada. No obstante esos primeros estudios terminológicos que apuntaban al sustantivo como elmentos denominativo-conceptual, otras teorías más recientes, entre las que destacamos la Teoría Comunicativa de la Terminología (Cabré, 1999) identifican otras estructuras morfosintácticas integradas por otros elementos no nominales portadores igualmente de esa carga conceptual. A partir de esta consideración, hemos seleccionado para este estudio el adjetivo relacional en tanto que representa otra categoría gramatical distinta al sustantivo y mantiene un vínculo con éste debido a su procedencia. Todo lo cual puede suscitar cierto interés terminológico. A través de esta investigación, nos hemos propuesto demostrar las siguientes hipótesis: 1. El adjetivo relacional aporta contenido especializado en su asociación con el componente nominal. 2. El adjetivo relacional es portador de un valor semántico que hace posible identificar con más precisión la relación conceptual de los elementos -adjetivo y sustantivo - de la combinación léxica resultante, especialmente en algunas formaciones ambiguas. 3. El adjetivo relacional, como modificador natural del sustantivo al que acompaña, podría imponer cierta restricción en sus combinaciones y, por tanto, hacer una selección discriminada de los integrantes de la combinación léxica especializada. Teniendo en cuenta las anteriores hipótesis, esta investigación ha delimitado y caracterizado el segmento léxico objeto de estudio: la ‘combinación léxica especializada (CLE)’ formalmente representada por la estructura sintáctica [adjR+n], en donde adjR es el adjetivo y n el sustantivo al que acompaña. De igual forma hemos descrito el marco teórico desde el que abordar nuestro análisis. Se trata de la teoría del Lexicón Generatvio (LG) y de la representación semántica (Pustojovsky, 1995) que propone como explicación de la generación de significados. Hemos analizado las distintas estructuras de representación léxica y en especial la estructura qualia a través de la cual hemos identificado la relación semántica que mantienen los dos ítems léxicos [adjR+n] de la estructura sintáctica de nuestro estudio. El estudio semántico de las dos piezas léxicas ha permitido, además, comprobar el valor denominativo del adjetivo en la combinación. Ha sido necesario elaborar un corpus de textos escritos en inglés y español pertenecientes al discurso de especialidad de las TIC. Este material ha sido procesado para nuestros fines utilizando distintas herramientas electrónicas. Se ha hecho uso de lexicones electrónicos, diccionarios online generales y de especialidad y corpus de referencia online, estos últimos para poder eventualmente validad nuetros datos. Asimismo se han utilizado motores de búsqueda, entre ellos WordNet Search 3.1, para obtener la información semántica de nuestros elementos léxicos. Nuestras conclusiones han corroborado las hipótesis que se planteaban en esta tesis, en especial la referente al valor denominativo-conceptual del adjetivo relacional el cual, junto con el sustantivo al que acompaña, forma parte de la representación cognitiva del lenguaje de especialidad de las TIC. Como continuación a este estudio se proponen sugerencias sobre líneas futuras de investigación así como el diseño de herramientas informáticas que pudieran incorporar estos datos semánticos como complemento de los ítems léxicos dotados de valor denominativo-conceptual. ABSTRACT This research falls within the field of the so-called Specialized Languages which for the purpose of this study is the Information and Communication Technology (ICT) discourse. Considering their several distinguishing features terminology concentrates our interest from the point of view of linguistics. It is broadly assumed that terms represent concepts of a subject field. For the classical view of terminology (Wüster, 1968) these terms are formally represented by nouns. Both lexicology and terminology have made significant contributions to the study of terms. Later research as well as other theories on Terminology such as the Communicative Theory of Terminology (Cabré, 1993) have shown that other lexical units can also represent knowledge organization. On these bases, we have focused our research on the relational adjective which represents a functional unit different from a noun while still connected to the noun by means of its nominal root. This may have a potential terminological interest. Therefore the present research is based on the next hypotheses: 1. The relational adjective conveys specialized information when combined with the noun. 2. The relational adjective has a semantic meaning which helps understand the conceptual relationship between the adjective and the noun being modified and disambiguate certain senses of the resulting lexical combination. 3. The relational adjective may impose some restrictions when choosing the nouns it modifies. Considering the above hypotheses, this study has identified and described a multi-word lexical unit pattern [Radj+n] referred to as a Specialized Lexical Combination (SLC) linguistically realized by a relational adjective, Radj, and a noun, n. The analysis of such a syntactic pattern is addressed from the framework of the Generative Lexicon (Pustojovsky, 1995). Such theory provides several levels of semantic description which help lexical decomposition performed generatively. These levels of semantic representation are connected through generative operations or generative devices which account for the compositional interpretation of any linguistic utterance in a given context. This study analyses these different levels and focuses on one of them, i.e. the qualia structure since it may encode the conceptual meaning of the syntactic pattern [Radj+n]. The semantic study of these two lexical items has ultimately confirmed the conceptual meaning of the relational adjective. A corpus made of online ICT articles from magazines written in English and Spanish – some being their translations - has been used for the word extraction. For this purpose some word processing software packages have been employed. Moreover online general language and specialized language dictionaries have been consulted. Search engines, namely WordNet Search 3.1, have been also exploited to find the semantic information of our lexical units. Online reference corpora in English and Spanish have been used for a contrastive analysis of our data. Finally our conclusions have confirmed our initial hypotheses, i.e. relational adjectives are specialized lexical units which together with the nouns are part of the knowledge representation of the ICT subject field. Proposals for new research have been made together with some other suggestions for the design of computer applications to visually show the conceptual meaning of certain lexical units.

Innovación educativa en las redes sociales online: un estudio en la educación superior

Las redes sociales son tan antiguas como las relaciones entre los humanos, ya que las labores de cooperación siempre fueron imprescindibles en los procesos de asociación, tanto los formados por simples células hasta los constituidos por seres vivos. La sociedad está formada por una gran cantidad de situaciones que fomentan dicha colaboración. Desde la creación del Espacio Europeo de Educación Superior se ha promovido la utilización de entornos virtuales de aprendizaje que favorezcan una evaluación más transparente y objetiva. Las redes sociales online son las interfaces digitales más utilizadas por los estudiantes universitarios, por lo que son muchos los expertos que recomiendan analizar la utilidad educativa de este tipo de aplicaciones. Siguiendo estas recomendaciones se implementó una red social online, llamada Formatio, que se utilizó para apoyar el proceso de enseñanza y aprendizaje en la educación superior. El objetivo general de esta tesis doctoral fue valorar el nivel de aceptación de este entorno virtual de aprendizaje para los estudiantes universitarios que participaron en este estudio. Para evaluar el uso de la plataforma se analizaron las actividades generadas por los 172 estudiantes, seleccionados aleatoriamente, matriculados en la asignatura de Estadística y TIC en el curso 2010/2011, del Grado en Ciencias de la Actividad Física y el Deporte. Con el objetivo de estimar la utilidad educativa de las redes sociales online se diseñó y validó el instrumento de Valoración de Recursos Educativos Online (VREO), que fue aplicado a otra muestra aleatoria de 452 estudiantes de la misma facultad durante el curso 2011/2012. Los resultados confirman el éxito de este tipo de espacios virtuales gracias a la alta frecuencia de uso conseguida y a las buenas puntuaciones obtenidas por los alumnos, quienes tienen una buena opinión sobre las ventajas de usar las redes sociales online en la educación superior. De todos los recursos analizados la red social online Formatio ha sido la opción mejor valorada, seguida de Moodle y Facebook en segundo y tercer lugar, y de Twitter y YouTube, en cuarta y en quinta posición. Este estudio establece un punto de partida para futuras investigaciones encaminadas a obtener ciertos indicadores cualitativos y cuantitativos que faciliten una evaluación más justa de los actores integrantes de los sistemas educativos, que ayude a abrir las puertas de nuestra sociedad a la responsabilidad, la eficiencia, la transparencia y la objetividad. ABSTRACT Social networks are as old as human relations, since cooperative work has always been indispensable in all processes of association, from those composed of simple cells to those formed by living beings. Society is shaped by a large amount of situations that stimulate this cooperation. Since the creation of the European Higher Education Area, the use of virtual learning environments that favor more transparent and objective evaluation has been promoted. On-line social networks are the digital interfaces most widely used by university students, which is the reason why many experts recommend an analysis of the educational utility of this type of applications. Following these recommendations, an on-line social network called Formatio was created, which was used in order to support the teaching and learning process in higher education. The general objective of this doctoral dissertation was to evaluate the level of acceptance of this virtual learning environment by the university students who participated in this study. In order to evaluate the use of the platform, the activity created by 172 students chosen at random was analyzed; they were registered in the course on Statistics and Information and Communication Technology of the degree program in Sciences of Physical Activity and Sport during the academic year 2010/2011. With the goal of appraising the educational utility of on-line social networks, a tool for Evaluation of On-line Educational Resources (EOER) was designed, validated, and applied to another random sample of 452 students from the same department during the academic year 2011/2012. The results confirm the success of this type of virtual spaces, thanks to the high frequency of use achieved and the good grades obtained by the students who had a favorable opinion of the advantages of using on-line social networks in higher education. Out of all the resources analyzed, the Formatio on-line social network was the option that received the best evaluation, followed by Moodle and Facebook, which were second and third, and Twitter and YouTube, in fourth and fifth place respectively. This study establishes a starting point for future research that aims to obtain certain qualitative and quantitative indicators that will make it easier to engage in a fairer evaluation of the parties involved in education systems, which will help open the doors of our society to responsibility, efficiency, transparency, and objectivity.

COMUNICAÇÃO E INOVAÇÃO EM PORTAIS CORPORATIVOS Os casos da Embraer, Natura, Faber-Castell e Rigesa

O trabalho analisa a relação entre Comunicação e Inovação nos Portais Corporativos das empresas Embraer, Natura, Faber-Castell e Rigesa. Ou seja, como essas instituições inovam em suas comunicações no meio on-line e como divulgam o conteúdo sobre Inovação. Estas empresas foram selecionadas como corpus central da pesquisa por estarem entre as mais inovadoras do Brasil, de acordo com a primeira versão do Índice Brasil de Inovação de 2007. A metodologia central para o desenvolvimento do projeto é a de Estudos de Caso Múltiplos, a partir da qual foi feita a comparação da comunicação digital por meio dos portais corporativos. Também são utilizados os recursos da Análise de Conteúdo e da Análise do Discurso. A proposta inclui também o exame da utilização das Tecnologias da Informação e Comunicação para a veiculação de informações institucionais e sobre Inovação por meio das Salas de Imprensa. E ainda, são destacadas as características dos profissionais responsáveis pela gestão dos portais corporativos. Os resultados da pesquisa evidenciam que há uma contradição entre as empresas serem inovadoras em produtos e processos, mas não no planejamento, gestão, arquitetura e divulgação da imagem institucional e de informações sobre inovação por meio dos portais corporativos. Revela ainda um nicho de mercado que precisa de profissionais especializados.(AU)

Orchestration of energy efficiency capabilities for a sustainable network management

The energy demand for operating Information and Communication Technology (ICT) systems has been growing, implying in high operational costs and consequent increase of carbon emissions. Both in datacenters and telecom infrastructures, the networks represent a significant amount of energy spending. Given that, there is an increased demand for energy eficiency solutions, and several capabilities to save energy have been proposed. However, it is very dificult to orchestrate such energy eficiency capabilities, i.e., coordinate or combine them in the same network, ensuring a conflict-free operation and choosing the best one for a given scenario, ensuring that a capability not suited to the current bandwidth utilization will not be applied and lead to congestion or packet loss. Also, there is no way in the literature to do this taking business directives into account. In this regard, a method able to orchestrate diferent energy eficiency capabilities is proposed considering the possible combinations and conflicts among them, as well as the best option for a given bandwidth utilization and network characteristics. In the proposed method, the business policies specified in a high-level interface are refined down to the network level in order to bring highlevel directives into the operation, and a Utility Function is used to combine energy eficiency and performance requirements. A Decision Tree able to determine what to do in each scenario is deployed in a Software Defined Network environment. The proposed method was validated with diferent experiments, testing the Utility Function, checking the extra savings when combining several capabilities, the decision tree interpolation and dynamicity aspects. The orchestration proved to be valid to solve the problem of finding the best combination for a given scenario, achieving additional savings due to the combination, besides ensuring a conflict-free operation.

On Modeling an Innovative Monitoring Network for Protecting and Managing Cultural Heritage from Risk Events

In this paper the model of an Innovative Monitoring Network involving properly connected nodes to develop an Information and Communication Technology (ICT) solution for preventive maintenance of historical centres from early warnings is proposed. It is well known that the protection of historical centres generally goes from a large-scale monitoring to a local one and it could be supported by a unique ICT solution. More in detail, the models of a virtually organized monitoring system could enable the implementation of automated analyses by presenting various alert levels. An adequate ICT solution tool would allow to define a monitoring network for a shared processing of data and results. Thus, a possible retrofit solution could be planned for pilot cases shared among the nodes of the network on the basis of a suitable procedure utilizing a retrofit catalogue. The final objective would consist in providing a model of an innovative tool to identify hazards, damages and possible retrofit solutions for historical centres, assuring an easy early warning support for stakeholders. The action could proactively target the needs and requirements of users, such as decision makers responsible for damage mitigation and safeguarding of cultural heritage assets.

Assessment of Web Content Accessibility Levels in Spanish Official Online Education Environments

Diversity-based designing, or the goal of ensuring that web-based information is accessible to as many diverse users as possible, has received growing international acceptance in recent years, with many countries introducing legislation to enforce it. This paper analyses web content accessibility levels in Spanish education portals according to the international guidelines established by the World Wide Web Consortium (W3C) and the Web Accessibility Initiative (WAI). Additionally, it suggests the calculation of an inaccessibility rate as a tool for measuring the degree of non-compliance with WAI Guidelines 2.0 as well as illustrating the significant gap that separates people with disabilities from digital education environments (with a 7.77% average). A total of twenty-one educational web portals with two different web depth levels (42 sampling units) were assessed for this purpose using the automated analysis tool Web Accessibility Test 2.0 (TAW, for its initials in Spanish). The present study reveals a general trend towards non-compliance with the technical accessibility recommendations issued by the W3C-WAI group (97.62% of the websites examined present mistakes in Level A conformance). Furthermore, despite the increasingly high number of legal and regulatory measures about accessibility, their practical application still remains unsatisfactory. A greater level of involvement must be assumed in order to raise awareness and enhance training efforts towards accessibility in the context of collective Information and Communication Technologies (ICTs), since this represents not only a necessity but also an ethical, social, political and legal commitment to be assumed by society.
