Public housing as urban heritage: experience and research approach in Spain

International conservation policies have incorporated the urban dimension of heritage, which considers the city as a historical continuum connected with the territory. However, the social housing complexes built in Europe throughout the second half of the 20th century lack legal entities and tools for their protection. Urban rehabilitation policies have substituted the initial demolition-replacement processes, by way of combining and coordinating protective measures. The rehabilitation of the Caño Roto Housing Estate (Madrid 1994-2004), as a precursor of a type of intervention widespread in Spain, is analysed with the aim of finding the actors, tools and decisions, so that the model can be optimised in future operations. The heritage dimension involves the development of the necessary means to make possible the conservation and functional updating of the buildings, as well as the development of new cultural, socioeconomic and environmental values, in order to add sustainability to the urban environment

Matlis duality, inverse systems and classification of Artin algebras

Treballs finals del Màster en Matemàtica Avançada, Facultat de Matemàtiques, Universitat de Barcelona: Curs: 2022-2023. Director: Joan Elías García[en] The aim of this project is to study the classification of some families of Artin algebras. In order to do that, we will study some important results of injective modules with the objective to be able to prove Matlis duality. In particular, we will study the case of Matlis duality when $R=\mathbf{k} \llbracket x_1, \ldots, x_n \rrbracket$ (the ring of the formal series) with maximal ideal $\mathfrak{m}=\left(x_1, \ldots, x_n\right)$. With this scenario, we are talking about Macaulay's duality. Using Macaulay's correspondence, we will be able to study important results as Hilbert functions, essential in the classification of algebras. We will study Gorenstein, level and compressed algebras. Along the paper, we use Singular [DGPS22] and the library Inverse SYST.LIB by Joan Elias [Eli14], which with we will compute some examples seen through the project

Vigne Nuove. Large-scale construction and social housing in the outskirts of Rome

[EN] The Piano di Zona Vigne Nuove Project by (Lucio Passarelli, Alfredo Lambertucci and Claudio Saratti, 1971-1979), a housing complex of 524 dwellings with common services located north of the urban continuum of Rome adapts some of the most important functional and constructive aspects in experimentation that has been taking place in Europe in the field of collective housing since the middle of the 20th century. The tectonic of the concrete acts as a nexus of a double system, horizontal which channels the public elements for facilities and services and vertical that contains housing cells intended for a diverse population. The research methodology stems from the relevance of both systems, public and private to give form to the analysis, establishing a relation with contemporary works. The project shows the overcoming of limitations of the functional city, by introducing intermediate elements and spaces of transition and social unity, and an improvement on traditional construction methods by establishing an effective standardization and an emergent prefabrication. The recuperation and highlighting of the work that this study entails, reveals a critical phase of renewal and maturity of modern architecture, and promotes it applicability in the evolution of the social housing and large-scale construction.[ES] El proyecto del Piano di Zona Vigne Nuove (Lucio Passarelli, Alfredo Lambertucci y Claudio Saratti, 1971-1979), un conjunto de 524 viviendas con servicios comunes situado al norte del continuo urbano de Roma, sintetiza algunos de los aspectos funcionales y constructivos más destacados en la experimentación que desde mediados del siglo XX se lleva a cabo en Europa en materia de vivienda colectiva. La tectónica del hormigón actúa como nexo de un doble sistema, horizontal que canaliza los elementos públicos de dotación y servicio, y vertical que contiene células de alojamiento destinadas a una población diversa. La metodología de la investigación parte de la importancia de ambos sistemas, público y privado, para estructurar el análisis, estableciendo relaciones con obras coetáneas. El proyecto muestra una superación de las limitaciones de la ciudad funcional, al introducir elementos y espacios intermedios de transición y cohesión social, y una superación de la construcción tradicional, al introducir una normalización eficaz y una incipiente prefabricación. La recuperación y puesta en valor de la obra que supone este estudio, descubre una fase crítica de renovación y madurez de la arquitectura moderna, y propicia su aplicabilidad en la evolución del hábitat social y la construcción a gran escala.Investigación realizada en ‘Sapienza’ Università di Roma y en la Real Academia de España en Roma (RAER).Cervero Sánchez, N.

Superconducting pair condensation and phase coherence in cuprates: experimental determination of the corresponding phase diagram in La2-x Srx CuO4

The aim of this thesis is to study the interrelationships between the normal state pseudogap, the phenomenology of the superconducting transition, the inhomogeneities and the disorder in the cuprate superconductors (HTSC). Specifically, we study the resistivity in the ab planes and the voltage-current (VI) curves in superconducting thin films of La(2-x)Sr(x)CuO(4). Brief panning of work:- Synthesis of films of La(2-x)Sr(x)CuO(4) with different dopings. - Characterization of the doping inhomogeneity and critical temperature by SQUID magnetometry. - Measurements of the superconducting phase coherence temperature through VI curves. - Analysis of the superconducting wave function condensation temperature using finite element simulations. - Measurement of the superconducting wave function condensation temperature through the resistivity measured in the ohmic regime

Matlis duality, inverse systems and classification of Artin algebras

Amb l’objectiu d’estudiar la classificació d’algunes famílies d’àlgebres artinianes, estudiarem alguns resultats importants sobre mòduls injectius i la dualitat de Matlis. Més específicament, estudiarem la correspondència de Macaulay, la dualitat de Matlis quan R = k[[x1, ... , xn]] amb l’ideal maximal m = (x1, ... , xn). Utilitzant aquesta, podem introduir-nos en les funcions de Hilbert, essencials en la classificació d’àlgebres artinianes. Tots aquests resultats han anat acompanyats de càlculs i exemples fets amb Singular [3] i la llibreria Inverse-syst.lib [4] del Dr. Joan Elias

Flipped classroom and Project Based Learning in Biology classroom: an innovation project for 1.º of eso. Experience assessment

The present article takes as a target to value the development of a didactic proposal for the Biology and Geology subject of 1st of eso. This proposal is based on flipped classroom (fc) and project based learning (pbl) methodologies and it centers on the development of the teaching-learning process of the anatomical and physiological characteristics of the different living beings included inside the so called Five Kingdoms.The fc is a pedagogic model that transfers the work of certain learning processes out of the classroom and uses the class time together with the experience of the teacher, to facilitate and to promote other processes of acquisition and practice of knowledge inside the classroom. Likewise, in the pbl model are the pupils those who set the rhythm for advancing in the acquisition of new knowledge, promoting the necessary thinking skills for a significant learning. Therefore both methodologies present themselves as a good option to conteract the problems associated with traditional Science education.</p

Mirada crítica sobre la vivienda colectiva actual. Conversación con Carmen Espegel

Carmen Espegel is Professor of Architectural Projects at the Higher Technical School of Architecture of the Polytechnic University of Madrid (ETSAM). Her career has encompassed three closely interrelated fields of activity: teaching, research and the profession of an architect. With her published works and her design projects she has bridged the gap between critique and practice of architecture, specifically, contemporary collective housing. Her profound knowledge drives apart from the purely theoretical and offers the viewpoint of a seasoned architect. She leads the Master of Advanced Architecture in Madrid and the Master in Collective Housing, which is jointly run by the Polytechnic University of Madrid and the Swiss Federal Institute of Technology in Zurich. She has collaborated with numerous universities in Europe, South America, the United States and Canada—this interview took place in Quebec, where Carmen is Visiting Professor at the city’s Laval University. Her research activity, focused on three fundamental branches—collective housing, critical theory and women and architecture—has driven her to lead the Collective Housing Research Group (GIVCO) and capture her critical thinking, with an important contribution in the area of residential design. In her role as a professional architect, her extensive and wide-ranging activity in tenders and works, which have received international recognition and awards, complements her incursions on the present-day manifestations of habitat, contributing to its development. Our conversation is organised in several themes that serve to connect personal reflections and aspects on the contemporary alternatives inherent in collective housing.La trayectoria de Carmen Espegel, Catedrática de Proyectos Arquitectónicos de la Escuela Técnica Superior de Arquitectura de Madrid, enlaza tres campos íntimamente relacionados, la docencia, la investigación y la profesión. Su obra publicada y construida, transita entre la crítica y la práctica de la arquitectura, y en concreto la vivienda colectiva de nuestro tiempo. Su extenso conocimiento se aleja de la vertiente teórica, para mostrar la mirada experimentada de una arquitecta. Es docente del Master en Proyectos Arquitectónicos Avanzados de la ETSAM y el Master in Collective Housing (MCH) impartido por la Universidad Politécnica de Madrid y el Swiss Federal Institute of Technology ETH de Zurich, y ha colaborado con numerosas universidades de Europa y América. En la actualidad es profesora invitada en Université Laval, Quebec, Canadá, desde donde nos concede esta entrevista. Su investigación, centrada en tres líneas fundamentales - mujer y arquitectura, crítica arquitectónica y vivienda colectiva -, le ha llevado a dirigir el Grupo de Investigación en Vivienda Colectiva (GIVCO), y plasmar su pensamiento crítico, con una importante aportación en la esfera residencial. En el ámbito profesional, la dilatada actividad formada por múltiples concursos y una extensa obra, ampliamente difundida y premiada, complementan sus incursiones en las actuales manifestaciones del hábitat, contribuyendo a su evolución. La conversación está estructurada en diversas temáticas, que permiten vincular aspectos y reflexiones personales sobre las alternativas contemporáneas que ofrece la vivienda colectiva

Democracia emocional en los medios sociales, el caso del pueblo egipcio : Emotional democracy in the social media, the case of the Egyptian people

La comunicación pretende dar a co nocer cómo los medios sociales han vuelto a ser los protagonistas de un hech o sin precedente, la revolución de los ciudadanos egipcios y su lucha por la libe rtad y la igualdad, principales derechos humanos frente a un gobierno atrincherado en el poder. El objeto de estudio se cent rará en analizar la información política difundida por los medios sociales sobre la protesta del pueb lo egipcio. Más aún, cuando el estudio del Centro Internacional de Asistencia a los Medios de Comunicación (CIMA) revela que el 50% de la población egipcia se info rma a través de Intern et, frente a un 34% que lee prensa escrita. A ello le sumamos la notable cultura de Internet entre los líderes del movimiento revolucionario demo crático, jóvenes que no superan los 30 años. Partimos de las siguientes interrogantes, ¿los medios sociales han demostrado ser una efectiva herramienta de compromiso co n la reivindicación del pueblo egipcio?, ¿qué medios sociales se utilizaron?, ¿qué función cumplieron?, ¿podemos hablar de un nuevo poder democrático?, ¿los medios sociales merecen especial reconocimiento?, ¿qué dicen los cibermedios de los medios sociales sobre Egipto? Utilizaremos el método del caso para dar respuesta a las premisas expuestas y desvelar la función real de los medios sociales. La movilización ciudadana en Egipto es la muestra de la importancia de los medios sociales dentro de los cambios políticos de un país. Herramienta de comunicación que ha sido capaz de informar, crear comunidades de vigilancia ciudadana, movilizar a un pueblo y desestabilizar a un gobierno con 30 años en el poder, a pesar que el régimen evito su uso. Ento nces, es posible hablar de democracia emocional en los medios sociales. Sin embargo, creemos que todos ellos no contribuyeron en la misma medida, incl uso es admisible que algunos de ellos hayan puesto algún obstáculo.This communication aims to show how social media has returned to be protagonists of an unprecedented event, th e Egyptian revolution and its struggle for freedom and equality, major human rights, against a government entrenched in power. The object of study will focus on analyz ing political information disseminated by social media on the protest of the Egyptian people. Especially when the study of the International Center for Assistance to Media (CIMA) reveals that 50% of the Egyptian population is reported via th e Internet, compared with 34% who read newspapers. Apart from that we add the re markable culture of the Internet among the leaders of the democratic revolutionary movement, young people who are under 30 years. We start with the following questions: soci al media has proven to be an effective tool to engage with the demands of the Egyptian people? What social media has been used? What role had did social me dia? Can we talk of a new democratic government?, Social media deserve special recognition?, What say cybermedia about social media on Egypt? We will use the case method to respond to the grounds set out and reveal the real role of social media. The mobilization of civil society in Egypt is the sign of the importance of social media within a country's political changes. Communication tool that has been able to inform, build communities of citizen oversight, to mobilize the people and destabilize a government 30 years in power, although the regime prevented its use. Then it's possible to talk about emotional democracy in the social media. However, we believe that all of them did not contribute to the same extent, it is even possible for some of them have put some obstacle

Los Beneficios de los programas de fidelización sobre la lealtad comportamental y actitudinal

Los programas de fidelización constituyen una herramienta de especial relevancia para las empresas que, con intención de incurrir en menores costes, apuestan por fidelizar a sus clientes. Este hecho es especialmente significativo en el sector turístico como consecuencia del importante papel que tienen las relaciones entre la empresa y sus clientes para el desarrollo del servicio (Alfaro, 2004). Los beneficios para los consumidores derivados de estos programas, económicos, sociales y estructurales, producen un efecto directo sobre la lealtad del mismo en sus dos dimensiones. La dimensión comportamental se materializa en la repetición del uso del servicio y la recomendación del mismo a amigos y/o familiares. La dimensión actitudinal, en la confianza y el compromiso adquirido por parte del consumidor hacia la empresa. No obstante, la fidelización del consumidor también estará condicionada por la satisfacción que el servicio genere en el mismo, ejerciendo un efecto mediador entre los programas de fidelización y la lealtad
