In recent decays university class small satellites are creating many opportunities for space research and professional trainings while at the same time responding to constrained budgets. In this work the main focus is on developing a simple and rapid structural sizing tool considering the main objectives of a low cost university class microsatellite project. In satellite projects, structure subsystem is one of the influential subsystems as a driver of the cost and acceptance of the final design. At the first steps of such projects there is no confirmed data regarding the launch vehicle or even in some cases there is no data for the satellite payload. Due to these facts, developing simple sizing tools at conceptual design phase for obtaining an over view of the effect of different variables is useful before entering complex calculations in detailed design phases. In this study, after developing a simple analytical model of satellite structure subsystem, a design space is evaluated with practical boundaries considering mass and dimensions constraints of such projects. The results are useful to give initial insight to establish the system level structural sizing

The objective of this paper is to address the methodological process of a teaching strategy for training project management complexity in postgraduate programs. The proposal is made up of different methods —intuitive, comparative, deductive, case study, problem-solving Project-Based Learning— and different activities inside and outside the classroom. This integration of methods motivated the current use of the concept of “learning strategy”. The strategy has two phases: firstly, the integration of the competences —technical, behavioral and contextual—in real projects; and secondly, the learning activity was oriented in upper level of knowledge, the evaluating the complexity for projects management in real situations. Both the competences in the learning strategy and the Project Complexity Evaluation are based on the ICB of IPMA. The learning strategy is applied in an international Postgraduate Program —Erasmus Mundus Master of Science— with the participation of five Universities of the European Union. This master program is fruit of a cooperative experience from one Educative Innovation Group of the UPM -GIE-Project-, two Research Groups of the UPM and the collaboration with other external agents to the university. Some reflections on the experience and the main success factors in the learning strategy were presented in the paper

In recent years, there has been continuing interest in the participation of university research groups in space technology studies by means of their own microsatellites. The involvement in such projects has some inherent challenges, such as limited budget and facilities. Also, due to the fact that the main objective of these projects is for educational purposes, usually there are uncertainties regarding their in orbit mission and scientific payloads at the early phases of the project. On the other hand, there are predetermined limitations for their mass and volume budgets owing to the fact that most of them are launched as an auxiliary payload in which the launch cost is reduced considerably. The satellite structure subsystem is the one which is most affected by the launcher constraints. This can affect different aspects, including dimensions, strength and frequency requirements. In this paper, the main focus is on developing a structural design sizing tool containing not only the primary structures properties as variables but also the system level variables such as payload mass budget and satellite total mass and dimensions. This approach enables the design team to obtain better insight into the design in an extended design envelope. The structural design sizing tool is based on analytical structural design formulas and appropriate assumptions including both static and dynamic models of the satellite. Finally, a Genetic Algorithm (GA) multiobjective optimization is applied to the design space. The result is a Pareto-optimal based on two objectives, minimum satellite total mass and maximum payload mass budget, which gives a useful insight to the design team at the early phases of the design.

The aim of this paper is to call into question those typologies conventionally used in developing the post-industrial urban fabric (streets, cityblocks, slabs, etc.), often catering to urban designs based on speculative interests and completely overlooking community interests. By defining the concepts of ?postpublic space? and ?reversible urban entities? and illustrating them with an exemplary case of Spanish residential architecture from the 1960s, we establish one possible way of tackling contemporary urban-residential projects. This alternative approach considers the relationship between residential systems and open space systems and promotes the continuity and/or alternation of scales between house and city in an effort to improve the urban quality of life for residents and external users.

A theory is developed of an electrostatic probe in a fully-ionized plasma in the presence of a strong magnetic field. The ratio of electron Larmor radius to probe transverse dimension is assumed to be small. Poisson's equation, together with kinetic equations for ions and electrons are considered. An asymptotic perturbation method of multiple scales is used by considering the characteristic lengths appearing in the problem. The leading behavior of the solution is found. The results obtained appear to apply to weaker fields also, agreeing with the solutions known in the limit of no magnetic field. The range of potentials for wich results are presented is limited. The basic effects produced by the field are a depletion of the plasma near the probe and a non-monotonic potential surrounding the probe. The ion saturation current is not changed but changes appear in both the floating potential Vf and the slope of the current-voltage diagram at Vf. The transition region extends beyond the space potential Vs,at wich point the current is largely reduced. The diagram does not have an exponential form in this region as commonly assumed. There exists saturation in electron collection. The extent to which the plasma is disturbed is determined. A cylindrical probe has no solution because of a logarithmic singularity at infinity. Extensions of the theory are considered.

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?

Esta tesis se ha realizado en el contexto del proyecto UPMSat-2, que es un microsatélite diseñado, construido y operado por el Instituto Universitario de Microgravedad "Ignacio Da Riva" (IDR / UPM) de la Universidad Politécnica de Madrid. Aplicación de la metodología Ingeniería Concurrente (Concurrent Engineering: CE) en el marco de la aplicación de diseño multidisciplinar (Multidisciplinary Design Optimization: MDO) es uno de los principales objetivos del presente trabajo. En los últimos años, ha habido un interés continuo en la participación de los grupos de investigación de las universidades en los estudios de la tecnología espacial a través de sus propios microsatélites. La participación en este tipo de proyectos tiene algunos desafíos inherentes, tales como presupuestos y servicios limitados. Además, debido al hecho de que el objetivo principal de estos proyectos es fundamentalmente educativo, por lo general hay incertidumbres en cuanto a su misión en órbita y cargas útiles en las primeras fases del proyecto. Por otro lado, existen limitaciones predeterminadas para sus presupuestos de masa, volumen y energía, debido al hecho de que la mayoría de ellos están considerados como una carga útil auxiliar para el lanzamiento. De este modo, el costo de lanzamiento se reduce considerablemente. En este contexto, el subsistema estructural del satélite es uno de los más afectados por las restricciones que impone el lanzador. Esto puede afectar a diferentes aspectos, incluyendo las dimensiones, la resistencia y los requisitos de frecuencia. En la primera parte de esta tesis, la atención se centra en el desarrollo de una herramienta de diseño del subsistema estructural que evalúa, no sólo las propiedades de la estructura primaria como variables, sino también algunas variables de nivel de sistema del satélite, como la masa de la carga útil y la masa y las dimensiones extremas de satélite. Este enfoque permite que el equipo de diseño obtenga una mejor visión del diseño en un espacio de diseño extendido. La herramienta de diseño estructural se basa en las fórmulas y los supuestos apropiados, incluyendo los modelos estáticos y dinámicos del satélite. Un algoritmo genético (Genetic Algorithm: GA) se aplica al espacio de diseño para optimizaciones de objetivo único y también multiobjetivo. El resultado de la optimización multiobjetivo es un Pareto-optimal basado en dos objetivo, la masa total de satélites mínimo y el máximo presupuesto de masa de carga útil. Por otro lado, la aplicación de los microsatélites en misiones espaciales es de interés por su menor coste y tiempo de desarrollo. La gran necesidad de las aplicaciones de teledetección es un fuerte impulsor de su popularidad en este tipo de misiones espaciales. Las misiones de tele-observación por satélite son esenciales para la investigación de los recursos de la tierra y el medio ambiente. En estas misiones existen interrelaciones estrechas entre diferentes requisitos como la altitud orbital, tiempo de revisita, el ciclo de vida y la resolución. Además, todos estos requisitos puede afectar a toda las características de diseño. Durante los últimos años la aplicación de CE en las misiones espaciales ha demostrado una gran ventaja para llegar al diseño óptimo, teniendo en cuenta tanto el rendimiento y el costo del proyecto. Un ejemplo bien conocido de la aplicación de CE es la CDF (Facilidad Diseño Concurrente) de la ESA (Agencia Espacial Europea). Está claro que para los proyectos de microsatélites universitarios tener o desarrollar una instalación de este tipo parece estar más allá de las capacidades del proyecto. Sin embargo, la práctica de la CE a cualquier escala puede ser beneficiosa para los microsatélites universitarios también. En la segunda parte de esta tesis, la atención se centra en el desarrollo de una estructura de optimización de diseño multidisciplinar (Multidisciplinary Design Optimization: MDO) aplicable a la fase de diseño conceptual de microsatélites de teledetección. Este enfoque permite que el equipo de diseño conozca la interacción entre las diferentes variables de diseño. El esquema MDO presentado no sólo incluye variables de nivel de sistema, tales como la masa total del satélite y la potencia total, sino también los requisitos de la misión como la resolución y tiempo de revisita. El proceso de diseño de microsatélites se divide en tres disciplinas; a) diseño de órbita, b) diseño de carga útil y c) diseño de plataforma. En primer lugar, se calculan diferentes parámetros de misión para un rango práctico de órbitas helio-síncronas (sun-synchronous orbits: SS-Os). Luego, según los parámetros orbitales y los datos de un instrumento como referencia, se calcula la masa y la potencia de la carga útil. El diseño de la plataforma del satélite se estima a partir de los datos de la masa y potencia de los diferentes subsistemas utilizando relaciones empíricas de diseño. El diseño del subsistema de potencia se realiza teniendo en cuenta variables de diseño más detalladas, como el escenario de la misión y diferentes tipos de células solares y baterías. El escenario se selecciona, de modo de obtener una banda de cobertura sobre la superficie terrestre paralelo al Ecuador después de cada intervalo de revisita. Con el objetivo de evaluar las interrelaciones entre las diferentes variables en el espacio de diseño, todas las disciplinas de diseño mencionados se combinan en un código unificado. Por último, una forma básica de MDO se ajusta a la herramienta de diseño de sistema de satélite. La optimización del diseño se realiza por medio de un GA con el único objetivo de minimizar la masa total de microsatélite. Según los resultados obtenidos de la aplicación del MDO, existen diferentes puntos de diseños óptimos, pero con diferentes variables de misión. Este análisis demuestra la aplicabilidad de MDO para los estudios de ingeniería de sistema en la fase de diseño conceptual en este tipo de proyectos. La principal conclusión de esta tesis, es que el diseño clásico de los satélites que por lo general comienza con la definición de la misión y la carga útil no es necesariamente la mejor metodología para todos los proyectos de satélites. Un microsatélite universitario, es un ejemplo de este tipo de proyectos. Por eso, se han desarrollado un conjunto de herramientas de diseño para encarar los estudios de la fase inicial de diseño. Este conjunto de herramientas incluye diferentes disciplinas de diseño centrados en el subsistema estructural y teniendo en cuenta una carga útil desconocida a priori. Los resultados demuestran que la mínima masa total del satélite y la máxima masa disponible para una carga útil desconocida a priori, son objetivos conflictivos. En este contexto para encontrar un Pareto-optimal se ha aplicado una optimización multiobjetivo. Según los resultados se concluye que la selección de la masa total por satélite en el rango de 40-60 kg puede considerarse como óptima para un proyecto de microsatélites universitario con carga útil desconocida a priori. También la metodología CE se ha aplicado al proceso de diseño conceptual de microsatélites de teledetección. Los resultados de la aplicación del CE proporcionan una clara comprensión de la interacción entre los requisitos de diseño de sistemas de satélites, tales como la masa total del microsatélite y la potencia y los requisitos de la misión como la resolución y el tiempo de revisita. La aplicación de MDO se hace con la minimización de la masa total de microsatélite. Los resultados de la aplicación de MDO aclaran la relación clara entre los diferentes requisitos de diseño del sistema y de misión, así como que permiten seleccionar las líneas de base para el diseño óptimo con el objetivo seleccionado en las primeras fase de diseño. ABSTRACT This thesis is done in the context of UPMSat-2 project, which is a microsatellite under design and manufacturing at the Instituto Universitario de Microgravedad “Ignacio Da Riva” (IDR/UPM) of the Universidad Politécnica de Madrid. Application of Concurrent Engineering (CE) methodology in the framework of Multidisciplinary Design application (MDO) is one of the main objectives of the present work. In recent years, there has been continuing interest in the participation of university research groups in space technology studies by means of their own microsatellites. The involvement in such projects has some inherent challenges, such as limited budget and facilities. Also, due to the fact that the main objective of these projects is for educational purposes, usually there are uncertainties regarding their in orbit mission and scientific payloads at the early phases of the project. On the other hand, there are predetermined limitations for their mass and volume budgets owing to the fact that most of them are launched as an auxiliary payload in which the launch cost is reduced considerably. The satellite structure subsystem is the one which is most affected by the launcher constraints. This can affect different aspects, including dimensions, strength and frequency requirements. In the first part of this thesis, the main focus is on developing a structural design sizing tool containing not only the primary structures properties as variables but also the satellite system level variables such as payload mass budget and satellite total mass and dimensions. This approach enables the design team to obtain better insight into the design in an extended design envelope. The structural design sizing tool is based on the analytical structural design formulas and appropriate assumptions including both static and dynamic models of the satellite. A Genetic Algorithm (GA) is applied to the design space for both single and multiobejective optimizations. The result of the multiobjective optimization is a Pareto-optimal based on two objectives, minimum satellite total mass and maximum payload mass budget. On the other hand, the application of the microsatellites is of interest for their less cost and response time. The high need for the remote sensing applications is a strong driver of their popularity in space missions. The satellite remote sensing missions are essential for long term research around the condition of the earth resources and environment. In remote sensing missions there are tight interrelations between different requirements such as orbital altitude, revisit time, mission cycle life and spatial resolution. Also, all of these requirements can affect the whole design characteristics. During the last years application of the CE in the space missions has demonstrated a great advantage to reach the optimum design base lines considering both the performance and the cost of the project. A well-known example of CE application is ESA (European Space Agency) CDF (Concurrent Design Facility). It is clear that for the university-class microsatellite projects having or developing such a facility seems beyond the project capabilities. Nevertheless practicing CE at any scale can be beneficiary for the university-class microsatellite projects. In the second part of this thesis, the main focus is on developing a MDO framework applicable to the conceptual design phase of the remote sensing microsatellites. This approach enables the design team to evaluate the interaction between the different system design variables. The presented MDO framework contains not only the system level variables such as the satellite total mass and total power, but also the mission requirements like the spatial resolution and the revisit time. The microsatellite sizing process is divided into the three major design disciplines; a) orbit design, b) payload sizing and c) bus sizing. First, different mission parameters for a practical range of sun-synchronous orbits (SS-Os) are calculated. Then, according to the orbital parameters and a reference remote sensing instrument, mass and power of the payload are calculated. Satellite bus sizing is done based on mass and power calculation of the different subsystems using design estimation relationships. In the satellite bus sizing, the power subsystem design is realized by considering more detailed design variables including a mission scenario and different types of solar cells and batteries. The mission scenario is selected in order to obtain a coverage belt on the earth surface parallel to the earth equatorial after each revisit time. In order to evaluate the interrelations between the different variables inside the design space all the mentioned design disciplines are combined in a unified code. The integrated satellite system sizing tool developed in this section is considered as an application of the CE to the conceptual design of the remote sensing microsatellite projects. Finally, in order to apply the MDO methodology to the design problem, a basic MDO framework is adjusted to the developed satellite system design tool. Design optimization is done by means of a GA single objective algorithm with the objective function as minimizing the microsatellite total mass. According to the results of MDO application, there exist different optimum design points all with the minimum satellite total mass but with different mission variables. This output demonstrates the successful applicability of MDO approach for system engineering trade-off studies at the conceptual design phase of the design in such projects. The main conclusion of this thesis is that the classical design approach for the satellite design which usually starts with the mission and payload definition is not necessarily the best approach for all of the satellite projects. The university-class microsatellite is an example for such projects. Due to this fact an integrated satellite sizing tool including different design disciplines focusing on the structural subsystem and considering unknown payload is developed. According to the results the satellite total mass and available mass for the unknown payload are conflictive objectives. In order to find the Pareto-optimal a multiobjective GA optimization is conducted. Based on the optimization results it is concluded that selecting the satellite total mass in the range of 40-60 kg can be considered as an optimum approach for a university-class microsatellite project with unknown payload(s). Also, the CE methodology is applied to the remote sensing microsatellites conceptual design process. The results of CE application provide a clear understanding of the interaction between satellite system design requirements such as satellite total mass and power and the satellite mission variables such as revisit time and spatial resolution. The MDO application is done with the total mass minimization of a remote sensing satellite. The results from the MDO application clarify the unclear relationship between different system and mission design variables as well as the optimum design base lines according to the selected objective during the initial design phases.

A Space tether is a thin, multi-kilometers long conductive wire, joining a satellite and some opposite end mass, and keeping vertical in orbit by the gravity-gradient. The ambient plasma, being highly conductive, is equipotential in its own co-moving frame. In the tether frame, in relative motion however, there is in the plasma a motional electric field of order of 100 V/km, product of (near) orbital velocity and geomagnetic field. The electromotive force established over the tether length allows plasma contactor devices to collect electrons at one polarized-positive (anodic) end and eject electrons at the opposite end, setting up a current along a standard, fully insulated tether. The Lorentz force exerted on the current by the geomagnetic field itself is always drag; this relies on just thermodynamics, like air drag. The bare tether concept, introduced in 1992 at the Universidad Politécnica de Madrid (UPM), takes away the insulation and has electrons collected over the tether segment coming out polarized positive; the concept rests on 2D (Langmuir probe) current-collection in plasmas being greatly more efficient than 3D collection. A Plasma Contactor ejects electrons at the cathodic end. A bare tether with a thin-tape cross section has much greater perimeter and de-orbits much faster than a (corresponding) round bare tether of equal length and mass. Further, tethers being long and thin, they are prone to cuts by abundant small space debris, but BETs has shown that the tape has a probability of being cut per unit time smaller by more than one order of magnitude than the corresponding round tether (debris comparable to its width are much less abundant than debris comparable to the radius of the corresponding round tether). Also, the tape collects much more current, and de-orbits much faster, than a corresponding multi-line “tape” made of thin round wires cross-connected to survive debris cuts. Tethers use a dissipative mechanism quite different from air drag and can de-orbit in just a few months; also, tape tethers are much lighter than round tethers of equal length and perimeter, which can capture equal current. The 3 disparate tape dimensions allow easily scalable design. Switching the cathodic Contactor off-on allows maneuvering to avoid catastrophic collisions with big tracked debris. Lorentz braking is as reliable as air drag. Tethers are still reasonably effective at high inclinations, where the motional field is small, because the geomagnetic field is not just a dipole along the Earth polar axis. BETs is the EC FP7/Space Project 262972, financed in about 1.8 million euros, from 1 November 2010 to 31 January 2014, and carrying out RTD work on de-orbiting space debris. Coordinated by UPM, it has partners Università di Padova, ONERA-Toulouse, Colorado State University, SME Emxys, DLR–Bremen, and Fundación Tecnalia. BETs work involves 1) Designing, building, and ground-testing basic hardware subsystems Cathodic Plasma Contactor, Tether Deployment Mechanism, Power Control Module, and Tape with crosswise and lengthwise structure. 2) Testing current collection and verifying tether dynamical stability. 3) Preliminary design of tape dimensions for a generic mission, conducive to low system-to-satellite mass ratio and probability of cut by small debris, and ohmic-effects regime of tether current for fast de-orbiting. Reaching TRL 4-5, BETs appears ready for in-orbit demostration.

Los nuevos comportamientos urbanos nos permiten observar cada vez con más frecuencia en nuestras calles y plazas realidades que siempre habíamos considerado domésticas. Al contrario también pasa, todos los días vivimos en nuestras casas situaciones que implican relacionarnos con personas que no son de nuestro núcleo familiar. El diseño doméstico de nuestras ciudades y el urbanismo del diseño de interiores parecen herramientas oportunas en el mundo que nos ha tocado vivir. Esto nos lleva a pensar que los espacios públicos y privados son términos simplificados, definidos en base a conceptos de propiedad para organizar la ciudad. En cambio, sus usos y vivencias, su gestión y sus comportamientos se han complejizado, distorsionando la terminología convencional hasta hacerla obsoleta. En este contexto, considerado también el marco socioeconómico actual, surgen las “acciones de abajo a arriba” como nuevo paradigma o modelo de renovación urbana, que entienden la involucración del ciudadano como parte activa en el proceso de construcción de la urbe desde la misma gestación del proyecto, frente a las acciones habituales que consideran al usuario como mero receptor de las propuestas. Un ciudadano que parece estar cada vez más radicalizado y una administración que parece asustarse ante el desconcierto que el acercamiento al ciudadano puede acarrear, han ocasionado por un lado, espacios “gueto” de carácter casi anárquico y, por el otro lado, lugares tan institucionalizados que derivan en espacios asociados a la administración y ajenos al ciudadano. Por ello, se considera imprescindible la colaboración entre ambos poderes. De acuerdo con el discurso que precede, dentro de un marco comparativo, se estudian 5 supuestos seleccionados de las ciudades Madrid y Zaragoza. Madrid porque es referencia nacional e internacional en el desarrollo urbano a través de procesos ‘abajo arriba’. Zaragoza porque es una ciudad ‘media’ que históricamente no se ha definido por estrategias urbanas claras, ya sean de carácter social o institucional. Sin embargo, en el momento actual se pueden identificar planteamientos relacionados con la recuperación de construcciones y espacios vacantes que pueden ser determinantes a la hora de alcanzar equilibrios con los intensos procesos institucionales acaecidos en las dos últimas décadas. De los procesos urbanos registrados en cada lugar, desarrollados en construcciones y espacios vacantes, he seleccionado: Construcciones Vacantes Madrid |Tabacalera de Lavapiés Zaragoza | Antiguo I.E.S. Luis Buñuel y antiguo Convento de Mínimos Espacios Vacantes Madrid | Campo de Cebada [solar] Zaragoza | Patio ‘antiguo I.E.S. Luis Buñuel [espacio libre] y plaza Eduardo Ibarra [espacio libre] El proyecto de investigación ha partido de las hipótesis de partida que siguen: UNA… Las ‘acciones de abajo arriba’ o renovación desde abajo no tienen cabida como elementos urbanos aislados sino conectados entre sí, posibilitando la producción de sinergias y la construcción de la ciudad; pudiendo ser consideradas acciones de desarrollo y enlace urbano, pues su objetivo es convertirse en motores del espacio público. Cuestión que es aplicable al resto de los procesos o acciones urbanas [‘horizontales’ o ‘institucionales’] DOS… La capacidad de adaptación manifestada por las ‘acciones de abajo arriba’ implica un marco ideológico de referencia asociado a la importancia de la construcción con mínimos recursos [Re-ocupación y/o Re- Construcción de estructuras urbanas en desuso] en los procesos urbanos descritos, como vía para comprender los concepto sostenibilidad y calidad figurativa de lo construido. Cuestión que es aplicable a la recuperación de aquellos aspectos de la arquitectura que la convierten en necesaria para la sociedad. Y tiene como objetivo: Identificar modelos de sostenibilidad urbana como una estrategia que va de lo individual a lo colectivo y que se transmite fundamentalmente con la acción, mezclando la innovación y la tecnología en múltiples ámbitos, utilizando los recursos naturales e intelectuales de una manera eficiente y entendiendo la inteligencia humana y sobre todo la inteligencia colectiva, como principio y justificación. Se han analizado los siguientes aspectos: sociales [participación ciudadana e implicación de la administración pública], urbanos [conexiones con otros colectivos o espacios urbanos / transformaciones urbanas a través de los procesos de gestión utilizados], constructivos [materiales utilizados en la re-construcción de construcciones y espacios vacantes / sistemas constructivos utilizados] y los relacionados con la sostenibilidad [sostenibilidad económica / sostenibilidad de mantenimiento / sostenibilidad funcional / inteligencia colectiva] El estudio de los aspectos considerados se ha desarrollado con las herramientas metodológicas siguientes: Entrevistas abiertas a expertos: se han obtenido respuestas de 25 personas expertas [5 por cada espacio o construcción vacante] relacionadas con las acciones urbanas sostenibles, la cultura y las relaciones sociales, y que también conocen los lugares y su entorno desde los puntos de vista urbano y construido. Son ‘tipos ideales’ asociados a uno de los cinco poderes que se manifiestan en la ciudad: el poder educativo [la universidad], el poder creativo [la cultura], el poder administrativo [la política], el poder empresarial [la empresa privada] y los usuarios [un usuario activo y representativo de cada lugar elegido que haya intervenido en la gestación del proceso]. Han sido personas que conocían el tejido social y urbano de la ciudad de Zaragoza y Madrid, ya que la herramienta ‘entrevista abierta a expertos’, recoge datos y opiniones planteadas en las construcciones y espacios vacantes ubicados en Zaragoza y Madrid. Entrevistas cerradas a usuarios: como la población de usuarios que se somete a la investigación es infinita o muy grande, resulta imposible o inconveniente realizar la obtención de los datos sobre todos aquellos elementos que la forman. Por lo tanto, he decidido estudiar sólo una parte de la población que denomino ‘tipos ideales’, obteniendo respuestas de 150 usuarios [30 personas por cada espacio o construcción vacante]. La selección de grupos de personas entrevistadas, debe permitir que los resultados sean representativos de la población total de usuarios. Además, la elección de ‘tipos ideales’ se ha identificado con los vecinos de los núcleos urbanos [o barrios] en los que se ubican las construcciones o espacios vacantes analizados. Observación estructurada: recoger información a través de la observación me ha permitido conocer las actuaciones y comportamientos de los ciudadanos en el medio urbano. Esto ha facilitado el estudio del medio a nivel práctico, valorando el uso que la sociedad da a las construcciones y a los espacios vacantes analizados. Es importante posicionar la estrategia en relación con el tema de investigación propuesto. Una estrategia que dibuje un panorama plural, desarrollado a través de herramientas sociales y constructivas que permitan que la arquitectura hable de cosas parecidas a lo que interesa a la ciudadanía. Para ello, propuse un catálogo de herramientas arquitectónicas que han permitido evaluar todas las propuestas. Un contexto de estrategias comunes que han descrito con los mismos códigos las distintas actuaciones analizadas. Estas herramientas tocan diferentes campos de interés. Desde las partes más tectónicas y constructivas, hasta las más ligadas con el desarrollo urbanístico y social. Acciones de participación colectiva: Experiencias o laboratorios urbanos participados por los alumnos del grado de arquitectura de la UNIZAR y los agentes sociales. Las acciones son una herramienta propositiva. Investigar y analizar proponiendo ha permitido que el análisis del contexto pueda llegar a capas de mucha más profundidad. No se ha trabajado estableciendo jerarquías de profesores y alumnos, sino que se ha intentado posibilitar la conexión de distintos agentes que trabajan coordinadamente durante el tiempo que han durado las acciones. Por un lado esto ha permite que cada integrante haya aportado al grupo lo que mejor sabe hacer y de la misma manera, que cada uno pueda aprender aquello de lo que tenga más ganas… y reflexionar sobre determinados aspectos objeto del análisis. Una vez interpretados los resultados, obtenidos a través de las herramientas metodológicas referenciadas, se ha concluido lo que sigue: Respecto de la Hipótesis de partida UNO LAS ACCIONES ‘ABAJO ARRIBA’ han revelado que no se puede entender ningún proceso de gestión urbana fuera de la participación ciudadana. El ‘ESPACIO LIBRE’ de una ciudad necesita lugares de autogestión, espacios de cogestión, movimientos de ‘arriba abajo’ y también modelos que todavía no sabemos ni que existen. LAS ACCIONES INSTITUCIONALES ‘ARRIBA ABAJO’ han demostrado que no han presentado permeabilidad ni relación con las circulaciones de entorno. Tampoco han tenido en cuenta a otras muchas personas, ‘usuarios productores’, a las que les interesan los procesos de búsqueda y las fórmulas de conexión más interactivas. Respecto de la hipótesis de partida DOS LAS ACCIONES ‘ABAJO ARRIBA’ han revelado que el ‘derecho a la ciudad’, paradigma defendido por Lefebvre desde el cual se piensa el urbanismo ciudadano, en estos supuestos podría entenderse como el ‘derecho a la infraestructura’. El ESPACIO LIBRE es infraestructura y se quiere para infraestructurar los derechos de cada uno. Y aunque también es verdad que estas acciones son simples destellos, han hecho visible otro paradigma de gestión y propuesta urbana que puede ser predominante en un futuro próximo. LAS ACCIONES INSTITUCIONALES ‘ARRIBA ABAJO’ han revelado que las intervenciones estuvieron enfocadas únicamente a la resolución de los procesos constructivos y a la incorporación del programa como un dato ‘problema’ que era necesario resolver para evitar la afección al diseño. ABSTRACT The new urban ways of behaviour let us watch more and more frequently in our streets and squares, realities that we had always considered as domestic. This also happens the other way round. Every day we have to go through situations at home which imply relationships with people who don’t belong to our family circle. The domestic design of our cities and the urban planning of indoor design seem to be adequate tools in the world we have to live in. This leads us to think that public and private spaces are simplified terms, defined according to concepts of property in order to organise the city. On the other hand, its uses and the experiences of people, its management and ways of behaviour is now more complex, changing the conventional terminology that has become outdated. In this context, ‘bottom-up’ actions arise as a new paradigm or model of urban renewal. These actions consider the active role of social participation in the process of building up the city from the very beginning, in comparison with the former way of acting that considered the user as mere receptor of the proposals. A citizen who seems to become more and more radical, and an administration that seems to be afraid of the unknown, have created both almost anarchic ghetto spaces and, on the other hand, spaces which have been so institutionalised that derive into areas associated to the administration but alienated from the citizen. For this reason, cowork of both forces is considered as crucial. In accordance with the above mentioned ideas and within a comparative framework, five situations chosen from the cities of Madrid and Zaragoza are studied. Madrid because is a national and international reference in urban development that uses “bottom-up” processes. Zaragoza because is a “medium-size” city that, historically, has not been defined by clear social or institutional urban strategies. Nevertheless, at the present time we can identify approaches on the recovery of constructions and empty areas that may be determining for reaching a balance with the intense institutional processes that have taken place in the two last decades. From the urban processes registered in every place and developed in vacant areas and constructions, I have chosen: Vacant constructions Madrid | Lavapiés Tobacco Factory Zaragoza | Old Secondary School Luis Buñuel and old Convent of the Minimos Vacant areas Madrid | Campo de Cebada [non-built site]. Zaragoza | Old courtyard of the secondary school and Eduardo Ibarra square [free space] The research project has been issued from the following starting hypotheses: ONE… “Bottom-up actions” or renewal from below have no place as isolated urban elements but as connected parts that can produce synergies and the construction of the city, and that can also be considered as actions producing urban development and links. This can also be applied to the rest of urban processes or actions [‘horizontal’ or ‘institutional’]. TWO… The capacity of adaptation shown by “bottom-up actions” implies an ideological framework of reference which is related to the importance of construction with minimal resources (re-occupation and/or reconstruction of urban structures in disuse) in the above mentioned urban processes, as a way for understanding the concepts of sustainability and the representational quality of what has been constructed. This can also be applied to the recovery of those architectural aspects that make architecture necessary for society. And its objective is: Identify models of urban sustainability as a strategy going from the individual to the collective, which are mainly transferred by action and that mix innovation and technology in many fields. Models that use natural and intellectual resources in an efficient way, and understand human intelligence and, above all, collective intelligence, as principle and justification. The following aspects have been analysed: social [civic participation and involvement of the public Administration], urban [connections with other collectives or urban spaces / urban transformation by the processes of administration used], constructive [materials used for the re-construction of empty spaces / construction systems used] and those focusing on sustainability [economic sustainability /maintenance sustainability /functional sustainability / collective intelligence]. For researching into the above mentioned aspects, the following methodological tools have been developed: Open interviews with experts: answers from 25 experts have been obtained [five for every vacant space or empty construction] on sustainable urban actions, culture and social relations, who also know the places and their environment from an urban and constructive point of view. These are “ideal types” linked to one of the five powers acting in the city: the educational power [University], the creative power [culture], the administration power [politics], the corporate power [private companies] and the users [an active and representative user for every place selected during the establishment of the process]. They were people who knew the social and urban fabric of Zaragoza and Madrid, since the “open interview for experts” tool collects data and points of view set out in vacant constructions and spaces of Zaragoza and Madrid. Close interviews with users: as the number of users targeted for the research is very big or infinite, it is impossible or inconvenient to get data from all its constituent parts. Therefore, I have decided to research into the part of the population that I call “ideal types”, obtaining answers from 150 users [30 people for every empty space or construction]. The selection of the groups of people interviewed must produce results which are representative of the total population of users. Furthermore, the election of “ideal types” has been identified with the inhabitants of urban areas [or city districts] in which the vacant spaces or constructions analysed are located. A structured observation: I have known the actions and ways of behaving of the citizens in the urban environment by means of collecting information after observation. Therefore, the practical research into the target environment has been easier by valuing the use that society gives to the empty constructions and spaces analysed. It is important to position the strategy with respect to the research subject proposed. It involves a strategy able to get an overview of a plural landscape, developed by social and constructive tools, allowing architecture to talk about topics which are interesting for city dwellers. Therefore, I proposed a set of architectural tools to evaluate all the proposals. A context of common strategies describing the different actions analysed by using the same codes. These tools focus on different fields of interests, from the most tectonic and constructive parts, to the most related to urban and social development. Actions on collective participation: experiences or urban laboratories shared by the students of architecture of the University of Zaragoza and social agents. The actions are a proactive tool. Researching and analysing by means of proposing, has allowed me to analyse the context and much deeper layers. This work has not been done by establishing ranks of professors and student, but trying to get an interaction between the different agents who work in close coordination during the implementation of the actions. This has allowed every agent to contribute the group what they do the best, and also every individual has had the possibility to learn what s/he prefers…, thinking about the different aspects targeted by the analysis. Once the different methodological tools have been interpreted, this is the conclusion: With regard to the initial hypothesis ONE “BOTTOM-UP” ACTIONS have proven that no process of urban management can be understood outside civic participation. The “FREE SPACE” of a city needs self-managed places, co-managed spaces, “up-bottom” movements, and also models whose existence is still ignored. “UP-BOTTOM” INSTITUTIONAL ACTIONS have proven that they have not presented neither permeability nor relation with local ideas. They have also disregarded many other people, the “usersproducers”, who are interested in the most interactive means of searching and connecting processes. With regard to the initial hypothesis TWO Under these premises, “BOTTOM-UP” ACTIONS have shown that the “right to the city”, a paradigm defended by Lefebvre and from which citizen-focused urbanism is conceived, could be considered as a “right to the infrastructures”. A FREE SPACE is an infrastructure and must be used to “infrastructure” the rights of every citizen. And, even though it is true that these actions are mere flashes, they have made visible another paradigm of management and urban proposal that can be prevailing in a near future. “UP-BOTTOM” INSTITUTIONAL ACTIONS have revealed that the interventions have only focused on resolving construction processes and the incorporation of the program as a “problem” data that was necessary to resolve in order to avoid its influence on the design.

Un nuevo sistema de gobernanza para afrontar los retos del siglo XXI en la educación universitaria en Perú basado en el modelo de análisis de políticas, surge de observar el efecto de la competencia en los mercados, de la distribución de los escasos recursos según productividad y rendimiento, y de la gestión ineficiente de las universidades ya que estos parámetros están cambiando los criterios de confianza y legitimidad del sistema universitario en Perú. Las universidades se perciben más como instituciones del sector público, mientras que los servicios que ofrecen deben más bien contribuir a la modernización de la sociedad emergente y a la economía del conocimiento. Las reformas universitarias- iniciadas en los años 80 - han estado inspiradas en las organizaciones universitarias exitosas que han logrado modificar su gobernanza y van dirigidas a transformar ciertas instituciones burocráticas en organizaciones capaces de desempeñar la función de actores en esta competición global por los recursos y los mejores talentos. En este contexto, la universidad peruana se enfrenta a dos grandes desafíos: el de adaptarse a las nuevas perspectivas mundiales, y el poder dar mejor respuesta a las demandas, necesidades y expectativas de la sociedad. Un cambio en el sistema de gobernanza para la educación superior universitaria dará una solución integral a estos desafíos permitiéndole enfrentar los problemas de la universidad para su desarrollo e inserción en las corrientes mundiales. La metodología planteada en la investigación es cualitativa parte del análisis de la realidad como un TODO, sin reducirlos a sus partes integrantes, con la interpretación de los hechos, buscando entender las variables que intervienen. Se propone una política para la educación universitaria en Perú que se permeabilice a la sociedad, cambiando el modelo de planificación de un modelo de reforma social a un modelo de análisis de políticas, donde el Estado Peruano actúe como único responsable de responder a la sociedad demandante como su representante legal, y con unos organismo externo e independiente que siente las bases de la práctica, como se está haciendo en muchos modelos universitarios del mundo. Esta investigación presenta una primera fase conceptual, que aborda la evolución histórica de las universidades en el Perú, analizando y clarificando las fuerzas impulsoras a través del tiempo y distinguir las principales líneas que le imprimen dirección y sentido a los cambios de una realidad educativa universitaria. Así mismo, en esta fase se hace un análisis de la situación actual de las universidades en el Perú para llegar a determinar en qué situación se encuentra y si está preparada para enfrentar los retos de la educación universitaria mundial, para esto se analizan los modelos universitarios de mayor prestigio en el mundo. El marco teórico anterior permite sentar, en una segunda fase de la investigación, las bases científicas del modelo que se propone: el modelo de planificación de análisis de políticas para el sistema universitario peruano. Este modelo de ámbito público propuesto para la educación universitaria peruana basa su estrategia en un modelo de planificación con un objetivo común: “Mejorar la calidad de la educación superior universitaria peruana con el fin de aumentar la empleabilidad y la movilidad de los ciudadanos así como la competitividad internacional de la educación universitaria en Perú”, y con unas líneas de acción concretadas en cuatro objetivos específicos: 1) competencias (genéricas y específicas de las áreas temáticas); 2) enfoques de enseñanza, aprendizaje y evaluación; 3) créditos académicos; 4) calidad de los programa. Así como los fundamentos metodológicos del modelo de análisis de políticas, utilizado como estructura política, teniendo en cuenta las características básicas del modelo: a) Planificación desde arriba; b) Se centra en la toma de decisiones; c) Separación entre conocimiento experto y decisión; d) El estudio de los resultados orienta el proceso decisor. Finalmente, se analiza una fase de validación del modelo propuesto para la educación superior universitaria peruana, con los avances ya realizados en Perú en temas de educación superior, como es, el actual contexto de la nueva Ley Universitaria N°30220 promulgada el 8 de julio de 2014, la creación del SUNEDU y la reorganización del SINEACE, que tienen como propósito atender la crisis universitaria centrada en tres ejes principales incluidos en la ley, considerados como bases para una reforma. Primero, el Estado asume la rectoría de las políticas educativas en todos los niveles educativos. El segundo aspecto consiste en instalar un mecanismo de regulación de la calidad que junto con la reestructuración de aquellos otros existentes debieran sentar las bases para que las familias y estudiantes tengan la garantía pública de que el servicio que se ofrece, sin importar sus características particulares, presenten un mínimo común de calidad y un tercer aspecto es que la ley se reafirma en que la universidad es un espacio de construcción de conocimiento basado en la investigación y la formación integral. Las finalidades, la estructura y organización, las formas de graduación, las características del cuerpo docente, la obligatoriedad por los estudios generales, etc., indican que la reflexión académica es el centro articulador de la vida universitaria. Esta validación también se ha confrontado con los resultados de las entrevistas cualitativas a juicio de experto que se han realizado a rectores de universidades públicas y privadas así como a rectores miembros de la ex ANR, miembros de organizaciones como CONCYTEC, IEP, CNE, CONEAU, ICACIT e investigadores en educación superior, con la finalidad de analizar la sostenibilidad del modelo propuesto en el tiempo. Los resultados evidencian, que en el sistema universitario peruano se puede implementar un cambio hacía un modelo de educación superior universitaria, con una política educativa que se base en un objetivo común claramente definido, un calendario para lograrlo y un conjunto objetivos específicos, con un cambio de estructura política de reforma social a un modelo de análisis de políticas. Así mismo se muestran los distintos aspectos que los interesados en la educación superior universitaria deben considerar, si se quiere ocupar un espacio en el futuro y si interesa que la universidad peruana pueda contribuir para que la sociedad se forje caminos posibles a través de una buena docencia que se refleje en su investigación, con alumnos internacionales, sobre todo, en los postgrados; con un investigación que se traduzca en publicaciones, patentes, etc., de impacto mundial, con relevancia en la sociedad porque contribuye a su desarrollo, concretándose en trabajos de muy diversos tipos, promovidos junto con empresas, gobiernos en sus diversos niveles, instituciones públicas o privadas, etc., para que aporten financiación a la universidad. ABSTRACT A new system of governance to meet the challenges of the twenty-first century university education in Peru based on the model of policy analysis, comes to observe the effect of market competition, distribution of scarce resources according to productivity and performance, and inefficient management of universities as these parameters are changing the criteria of trust and legitimacy of the university system in Peru. Universities are perceived more as public sector institutions, while the services provided should rather contribute to the modernization of society and the emerging knowledge economy. The-university reforms initiated in the 80s - have been inspired by successful university organizations that have succeeded in changing its governance and as attempting to transform certain bureaucratic institutions into organizations that act as actors in this global competition for resources and top talent. In this context, the Peruvian university faces two major challenges: to adapt to the new global outlook, and to better respond to the demands, needs and expectations of society. A change in the system of governance for university education give a comprehensive solution to address these challenges by allowing the problems of the university development and integration into global flows. The methodology proposed in this research is qualitative part of the analysis of reality as a whole, without reducing them to their constituent parts, with the interpretation of the facts, seeking to understand the variables involved. a policy for university education in Peru that permeabilizes society is proposed changing the planning model of a model of social reform a model of policy analysis, where the Peruvian State to act as the sole responsible for responding to the applicant as its legal representative, and with external and independent body that provides the basis of practice, as is being done in many university models in the world. This research presents an initial conceptual phase, which deals with the historical development of universities in Peru, analyzing and clarifying the driving forces over time and distinguish the main lines that give direction and meaning to changes in university educational reality. Also, at this stage an analysis of the current situation of universities in Peru is done to be able to determine what the situation is and whether it is prepared to meet the challenges of the global higher education, for this university models are analyzed most prestigious in the world. The above theoretical framework allows to lay in a second phase of research, the scientific basis of the model proposed: the planning model of policy analysis for the Peruvian university system. This proposed model of public sphere for the Peruvian college bases its strategy on a planning model with a common goal: "To improve the quality of the Peruvian university education in order to enhance the employability and mobility of citizens and the international competitiveness of higher education in Peru ", and lines of action materialized in four specific objectives: 1) competences (generic and specific subject areas); 2) approaches to teaching, learning and assessment; 3) credits; 4) quality of the program. As well as the methodological foundations of policy analysis model, used as political structure, taking into account the basic characteristics of the model: a) Planning from above; b) focuses on decision making; c) Separation between expertise and decision; d) The study of the results process guides the decision maker. Finally, a validation phase of the proposed Peruvian university higher education, with the progress already made in Peru on issues of higher education model is analyzed, as is the current context of the new University Law No. 30220 promulgated on July 8 2014, the creation of SUNEDU and reorganization of SINEACE, which are intended to serve the university crisis centered on three main areas included in the law, considered as the basis for reform. First, the State assumes the stewardship of education policies at all educational levels. The second aspect is to install a mechanism for regulating the quality along with the restructuring of those existing ones should lay the foundation for families and students to guarantee that public service is offered, regardless of their individual characteristics, are of common minimum quality and a third aspect is that the law reaffirms that the university is building a space of research-based knowledge and comprehensive training. The aims, structure and organization, forms of graduation, faculty characteristics, the requirement for the general studies, etc., indicate that the academic reflection is the coordinating center of university life. This validation has also been confronted with the results of qualitative interviews with expert judgment that has been made to directors of public and private universities as well as leading members of the former ANR members of organizations like CONCYTEC, IEP, CNE, CONEAU, ICACIT and researchers in higher education, in order to analyze the sustainability of the proposed model in time. The results show, that the Peruvian university system can implement a change to a model of university education, an educational policy based on clearly defined common goal, a timetable for achieving specific objectives set and, with a change social policy structure to a model of reform policy analysis. It also shows the various aspects that those interested in university education should consider, if you want to occupy a space in the future and if interested in the Peruvian university can contribute to society possible paths is forged through research good teaching, international students, especially in graduate programs; with research that results in publications, patents, etc., global impact, relevance to society because it contributes to their development taking shape in very different types of jobs, promoted with businesses, governments at various levels, public institutions or private, etc., to provide funding to the university.
