Self-Organizing Architectural design based on Morphogenetic Programming.

In this paper, we present our research into self-organizing building algorithms. This idea of self-organization of animal/plants behaviour interests researchers to explore the mechanisms required for this emergent phenomena and try to apply them in other domains. We were able to implement a typical construction algorithm in a 3D simulation environment and reproduce the results of previous research in the area. LSystems, morphogenetic programming and wasp nest building are explained in order to understand self-organizing models. We proposed Grammatical swarm as a good tool to optimize building structures.

Patent elucidation for clil and vice versa understanding the inventor´s mind

In this paper we present an English-medium instruction (EMI) team-teaching initiative to be soon implemented within the Agronomic Engineering masters programme at the Technical University of Madrid (UPM). Through the patent genre we not only intend to teach specific agronomical syllabi contents synchronically and diachronically, but also broaden our students’ academic and professional literacies, help them practice and improve their communication abilities in English as a lingua franca, and motivate them as future autonomous professionals while fostering the exercise of higher-level transversal skills—critical thinking, creativity, cooperation, and entrepreneurship. We begin by introducing the current mobility trends in higher education contexts and the common misconceptions surrounding the notion of patent, and get on to describe the design and evaluation procedures of the course. To conclude, we recapitulate the main benefits of our pedagogical proposal and open windows onto further didactic applications.

Auto-Emergencia de Comunicación Sintáctica en Entornos Estáticos y Dinámicos para Grupos de Robots mediante Evolución Gramatical y Aprendizaje por Refuerzo

La idea de dotar a un grupo de robots o agentes artificiales de un lenguaje ha sido objeto de intenso estudio en las ultimas décadas. Como no podía ser de otra forma los primeros intentos se enfocaron hacia el estudio de la emergencia de vocabularios compartidos convencionalmente por el grupo de robots. Las ventajas que puede ofrecer un léxico común son evidentes, como también lo es que un lenguaje con una estructura más compleja, en la que se pudieran combinar palabras, sería todavía más beneficioso. Surgen así algunas propuestas enfocadas hacia la emergencia de un lenguaje consensuado que muestre una estructura sintáctica similar al lenguaje humano, entre las que se encuentra este trabajo. Tomar el lenguaje humano como modelo supone adoptar algunas de las hipótesis y teorías que disciplinas como la filosofía, la psicología o la lingüística entre otras se han encargado de proponer. Según estas aproximaciones teóricas el lenguaje presenta una doble dimension formal y funcional. En base a su dimensión formal parece claro que el lenguaje sigue unas reglas, por lo que el uso de una gramática se ha considerado esencial para su representación, pero también porque las gramáticas son un dispositivo muy sencillo y potente que permite generar fácilmente estructuras simbólicas. En cuanto a la dimension funcional se ha tenido en cuenta la teoría quizá más influyente de los últimos tiempos, que no es otra que la Teoría de los Actos del Habla. Esta teoría se basa en la idea de Wittgenstein por la que el significado reside en el uso del lenguaje, hasta el punto de que éste se entiende como una manera de actuar y de comportarse, en definitiva como una forma de vida. Teniendo presentes estas premisas en esta tesis se pretende experimentar con modelos computacionales que permitan a un grupo de robots alcanzar un lenguaje común de manera autónoma, simplemente mediante interacciones individuales entre los robots, en forma de juegos de lenguaje. Para ello se proponen tres modelos distintos de lenguaje: • Un modelo basado en gramáticas probabilísticas y aprendizaje por refuerzo en el que las interacciones y el uso del lenguaje son claves para su emergencia y que emplea una gramática generativa estática y diseñada de antemano. Este modelo se aplica a dos grupos distintos: uno formado exclusivamente por robots y otro que combina robots y un humano, de manera que en este segundo caso se plantea un aprendizaje supervisado por humanos. • Un modelo basado en evolución gramatical que permite estudiar no solo el consenso sintáctico, sino también cuestiones relativas a la génesis del lenguaje y que emplea una gramática universal a partir de la cual los robots pueden evolucionar por sí mismos la gramática más apropiada según la situación lingüística que traten en cada momento. • Un modelo basado en evolución gramatical y aprendizaje por refuerzo que toma aspectos de los anteriores y amplia las posibilidades de los robots al permitir desarrollar un lenguaje que se adapta a situaciones lingüísticas dinámicas que pueden cambiar en el tiempo y también posibilita la imposición de restricciones de orden muy frecuentes en las estructuras sintácticas complejas. Todos los modelos implican un planteamiento descentralizado y auto-organizado, de manera que ninguno de los robots es el dueño del lenguaje y todos deben cooperar y colaborar de forma coordinada para lograr el consenso sintáctico. En cada caso se plantean experimentos que tienen como objetivo validar los modelos propuestos, tanto en lo relativo al éxito en la emergencia del lenguaje como en lo relacionado con cuestiones paralelas de importancia, como la interacción hombre-máquina o la propia génesis del lenguaje. ABSTRACT The idea of giving a language to a group of robots or artificial agents has been the subject of intense study in recent decades. The first attempts have focused on the development and emergence of a conventionally shared vocabulary. The advantages that can provide a common vocabulary are evident and therefore a more complex language that combines words would be even more beneficial. Thus some proposals are put forward towards the emergence of a consensual language with a sintactical structure in similar terms to the human language. This work follows this trend. Taking the human language as a model means taking some of the assumptions and theories that disciplines such as philosophy, psychology or linguistics among others have provided. According to these theoretical positions language has a double formal and functional dimension. Based on its formal dimension it seems clear that language follows rules, so that the use of a grammar has been considered essential for representation, but also because grammars are a very simple and powerful device that easily generates these symbolic structures. As for the functional dimension perhaps the most influential theory of recent times, the Theory of Speech Acts has been taken into account. This theory is based on the Wittgenstein’s idea about that the meaning lies in the use of language, to the extent that it is understood as a way of acting and behaving. Having into account these issues this work implements some computational models in order to test if they allow a group of robots to reach in an autonomous way a shared language by means of individual interaction among them, that is by means of language games. Specifically, three different models of language for robots are proposed: • A reinforcement learning based model in which interactions and language use are key to its emergence. This model uses a static probabilistic generative grammar which is designed beforehand. The model is applied to two different groups: one formed exclusively by robots and other combining robots and a human. Therefore, in the second case the learning process is supervised by the human. • A model based on grammatical evolution that allows us to study not only the syntactic consensus, but also the very genesis of language. This model uses a universal grammar that allows robots to evolve for themselves the most appropriate grammar according to the current linguistic situation they deal with. • A model based on grammatical evolution and reinforcement learning that takes aspects of the previous models and increases their possibilities. This model allows robots to develop a language in order to adapt to dynamic language situations that can change over time and also allows the imposition of syntactical order restrictions which are very common in complex syntactic structures. All models involve a decentralized and self-organized approach so that none of the robots is the language’s owner and everyone must cooperate and work together in a coordinated manner to achieve syntactic consensus. In each case experiments are presented in order to validate the proposed models, both in terms of success about the emergence of language and it relates to the study of important parallel issues, such as human-computer interaction or the very genesis of language.

Enhancing regression models for complex systems using evolutionary techniques for feature engineering

This work proposes an automatic methodology for modeling complex systems. Our methodology is based on the combination of Grammatical Evolution and classical regression to obtain an optimal set of features that take part of a linear and convex model. This technique provides both Feature Engineering and Symbolic Regression in order to infer accurate models with no effort or designer's expertise requirements. As advanced Cloud services are becoming mainstream, the contribution of data centers in the overall power consumption of modern cities is growing dramatically. These facilities consume from 10 to 100 times more power per square foot than typical office buildings. Modeling the power consumption for these infrastructures is crucial to anticipate the effects of aggressive optimization policies, but accurate and fast power modeling is a complex challenge for high-end servers not yet satisfied by analytical approaches. For this case study, our methodology minimizes error in power prediction. This work has been tested using real Cloud applications resulting on an average error in power estimation of 3.98%. Our work improves the possibilities of deriving Cloud energy efficient policies in Cloud data centers being applicable to other computing environments with similar characteristics.

A Comparative Analysis of Hedging in a Corpus of Two Written Legal Discourse Genres

Esta tesis doctoral, que es la culminación de mis estudios de doctorado impartidos por el Departamento de Lingüística Aplicada a la Ciencia y a la Tecnología de la Universidad Politécnica de Madrid, aborda el análisis del uso de la matización (hedging) en el lenguaje legal inglés siguiendo los postulados y principios de la análisis crítica de género (Bhatia, 2004) y empleando las herramientas de análisis de córpora WordSmith Tools versión 6 (Scott, 2014). Como refleja el título, el estudio se centra en la descripción y en el análisis contrastivo de las variedades léxico-sintácticas de los matizadores del discurso (hedges) y las estrategias discursivas que con ellos se llevan a cabo, además de las funciones que éstas desempeñan en un corpus de sentencias del Tribunal Supremo de EE. UU., y de artículos jurídicos de investigación americanos, relacionando, en la medida posible, éstas con los rasgos determinantes de los dos géneros, desde una perspectiva socio-cognitiva. El elemento innovador que ofrece es que, a pesar de los numerosos estudios que se han podido realizar sobre los matizadores del discurso en el inglés general (Lakoff, 1973; Hübler, 1983; Clemen, 1997; Markkanen and Schröder, 1997; Mauranen, 1997; Fetzer 2010; y Finnegan, 2010 entre otros) académico (Crompton, 1997; Meyer, 1997; Skelton, 1997; Martín Butragueňo, 2003) científico (Hyland, 1996a, 1996c, 1998c, 2007; Grabe and Kaplan, 1997; Salager-Meyer, 1997 Varttala, 2001) médico (Prince, 1982; Salager-Meyer, 1994; Skelton, 1997), y, en menor medida el inglés legal (Toska, 2012), no existe ningún tipo de investigación que vincule los distintos usos de la matización a las características genéricas de las comunicaciones profesionales. Dentro del lenguaje legal, la matización confirma su dependencia tanto de las expectativas a macro-nivel de la comunidad de discurso, como de las intenciones a micro-nivel del escritor de la comunicación, variando en función de los propósitos comunicativos del género ya sean éstos educativos, pedagógicos, interpersonales u operativos. El estudio pone de relieve el uso predominante de los verbos modales epistémicos y de los verbos léxicos como matizadores del discurso, estos últimos divididos en cuatro tipos (Hyland 1998c; Palmer 1986, 1990, 2001) especulativos, citativos, deductivos y sensoriales. La realización léxico-sintáctica del matizador puede señalar una de cuatro estrategias discursivas particulares (Namsaraev, 1997; Salager-Meyer, 1994), la indeterminación, la despersonalización, la subjectivisación, o la matización camuflada (camouflage hedging), cuya incidencia y función varia según género. La identificación y cuantificación de los distintos matizadores y estrategias empleados en los diferentes géneros del discurso legal puede tener implicaciones pedagógicos para los estudiantes de derecho no nativos que tienen que demostrar una competencia adecuada en su uso y procesamiento. ABSTRACT This doctoral thesis, which represents the culmination of my doctoral studies undertaken in the Department of Linguistics Applied to Science and Technology of the Universidad Politécnica de Madrid, focusses on the analysis of hedging in legal English following the principles of Critical Genre Analysis (Bhatia, 2004), and using WordSmith Tools version 6 (Scott, 2014) corpus analysis tools. As the title suggests, this study centers on the description and contrastive analysis of lexico-grammatical realizations of hedges and the discourse strategies which they can indicate, as well as the functions they can carry out, in a corpus of U.S. Supreme Court opinions and American law review articles. The study relates realization, incidence and function of hedging to the predominant generic characteristics of the two genres from a socio-cognitive perspective. While there have been numerous studies on hedging in general English (Lakoff, 1973; Hübler, 1983; Clemen, 1997; Markkanen and Schröder, 1997; Mauranen, 1997; Fetzer 2010; and Finnegan, 2010 among others) academic English (Crompton, 1997; Meyer, 1997; Skelton, 1997; Martín Butragueňo, 2003) scientific English (Hyland, 1996a, 1996c, 1998c, 2007; Grabe and Kaplan, 1997; Salager-Meyer, 1997 Varttala, 2001) medical English (Prince, 1982; Salager-Meyer, 1994; Skelton, 1997), and, to a lesser degree, legal English (Toska, 2012), this study is innovative in that it links the different realizations and functions of hedging to the generic characteristics of a particular professional communication. Within legal English, hedging has been found to depend on not only the macro-level expectations of the discourse community for a specific genre, but also on the micro-level intentions of the author of a communication, varying according to the educational, pedagogical, interpersonal or operative purposes the genre may have. The study highlights the predominance of epistemic modal verbs and lexical verbs as hedges, dividing the latter into four types (Hyland, 1998c; Palmer, 1986, 1990, 2001): speculative, quotative, deductive and sensorial. Lexical-grammatical realizations of hedges can signal one of four discourse strategies (Namsaraev, 1997; Salager-Meyer, 1994), indetermination, depersonalization, subjectivization and camouflage hedging, as well as fulfill a variety of functions. The identification and quantification of the different hedges and hedging strategies and functions in the two genres may have pedagogical implications for non-native law students who must demonstrate adequate competence in the production and interpretation of hedged discourse.

Materialidad poética: arquitectura suiza en el entorno de los Grisones 1992-2004

El entorno alpino de los Grisones ha sido un laboratorio donde experimentar un método arquitectónico procedente de diversas fuentes durante los años 70 en la ETHZ. Este método ha producido durante las últimas tres décadas un discurso teórico propiamente suizo alemán. La tradición continúa siendo un valor cultural para la comunidad alpina de los Grisones, que apuesta por seguir relacionando la arquitectura con su historia y su paisaje. La especificidad de cada entorno suizo alemán es un hecho obvio pero, por encima de sus rasgos característicos, hay un denominador común que les da unidad en silencio: se trata de una idea de la construcción. El fenómeno de los Grisones es territorial en su localización concreta, pero comparte el trasfondo teórico del resto de la arquitectura suizo alemana reciente. La tesis recorre transversalmente las condiciones que han dado lugar a esa trayectoria común hasta la actualidad, en que la arquitectura suizo alemana se halla precisamente en un momento de cambio generacional. La obra de Peter Märkli constituye en esta tesis un paradigma de la voluntad suizo alemana por formar parte de la continuidad cultural de la arquitectura, como una actitud de resistencia compartida frente al mundo globalizado. La tesis se articula a partir de ocho proyectos recientes, realizados por arquitectos suizo alemanes en el entorno del territorio alpino de los Grisones. Estos proyectos condensan la trayectoria arquitectónica suizo alemana durante el siglo XX, así como el fenómeno arquitectónico que ha tenido lugar en el entorno de los Grisones durante las últimas tres décadas. La tesis analiza a través de cada pareja de proyectos los episodios teóricos, artísticos y filosóficos más relevantes que se sintetizan en estas obras, así como sus referentes arquitectónicos y la dimensión trascendente de los materiales en los que la cultura suiza hunde sus raíces: la madera, la piedra y el hormigón. Las vanguardias pictóricas, el Movimiento Moderno y las corrientes humanistas y regionalistas que se fueron sucediendo durante el pasado siglo, configuran el escenario en el que tomó cuerpo la sensibilidad arquitectónica suizo alemana reciente, que emerge a través de la compleja red de relaciones establecidas entre el panorama suizo y el internacional. El mismo bagaje teórico subyace al territorio suizo alemán a nivel general, por lo que asociarlo a través de esta tesis a proyectos realizados en un entorno característico, permite acceder a una realización concreta de ese debate en un entorno tan particular como son los Grisones. La aproximación a los proyectos es de carácter fenomenológico: la experiencia directa de los mismos ha sido el sustrato fundamental del enfoque de la tesis. El trabajo de campo no se limitó a visitar los proyectos que vertebran la tesis, sino que trató de abarcar las obras más relevantes de la producción suizo alemana reciente en los Grisones, con el fin de adquirir cierto grado de sensibilidad perceptiva hacia la singularidad de su identidad territorial. La tesis hace especial hincapié en las obras de Peter Märkli y Peter Zumthor, representantes de los dos extremos del discurso suizo alemán reciente, respecto a la materialidad y al carácter de la secuencia espacial, sistemático o fluido respectivamente, pero que asimismo comparten el clasicismo formalista que subyace al fenómeno suizo alemán. Los dos proyectos que establecen el periodo 1992-2004 explorado por esta investigación constituyen dos hitos fundamentales. El Museo de La Congiunta en Giornico de Peter Märkli se construyó en 1992 y se erige a partir de entonces como un icono arquitectónico de la condensación típicamente suizo alemana de base reductiva. Este paradigma de síntesis conceptual y constructiva comenzó a forjarse en la década de 1930 de la mano del Konkrete Kunst formulado por Max Bill, que es la única manifestación artística genuinamente suiza del siglo XX y que desarrolló pictóricamente los valores de precisión, rigor, racionalismo y abstracción afines a la sensibilidad suizo alemana. En segundo lugar, el proyecto para la rehabilitación de la Villa Garbald y la construcción de la Torre Roccolo en Castasegna llevado a cabo por Miller & Maranta en 2004, supuso la consumación de la Analoge Architektur, que fue la primera corriente arquitectónica propiamente suiza, desarrollada durante la década de 1980 por Miroslav Sik. La Deutscher Tendenza es un periodo de la trayectoria suizo alemana reciente poco conocido, representado por una figura tan relevante como es Peter Zumthor. Las obras que proyectó Zumthor entre 1979 y 1985 forman parte de un periodo en que el arquitecto se encontraba profundamente influido por el neorracionalismo italiano, como ilustra la escuela de Churwalden de 1983. La arquitectura suizo alemana reciente exploró sistemáticamente los sistemas compositivos de las vanguardias pictóricas y del Movimiento Moderno, por encima de su formalismo concreto. La segunda fase de la obra de Zumthor entre 1985 y 1996 se caracteriza por la transfiguración del plano libre del sistema compositivo neoplasticista desarrollado por De Stijl, plano que adquirió grosor hasta convertirse en la caja articuladora de la fluidez de la secuencia espacial. El formalismo de Zumthor en esta fase implica la prioridad del esquema compositivo, compuesto por un perímetro regular en el que se reúnen las cajas que, como las superficies de color de las composiciones de Mondrian, articulan el espacio a su alrededor. La Residencia de Masans de Zumthor de 1993 es un proyecto canónico de este sistema compositivo, que culmina en el esquema radial de las Termas de Vals de 1996. La imagen poética se convirtió en el lenguaje propio del pensamiento de la arquitectura suizo alemana, que permitía una reflexión no verbal, a partir de unos pocos arquetipos fundamentales. Los arquitectos del Ticino buscaron en la Tendenza italiana durante la década de 1970 una alternativa al insostenible modelo territorial que estaba destruyendo su paisaje cultural. Algunos de estos arquitectos comenzaron a dar clase durante esa década en la ETHZ, por lo que transmitieron sus inquietudes al alumnado e introdujeron a Aldo Rossi en la facultad, que era uno de los máximos representantes de la Tendenza. El método analógico de Rossi, basado en la psicología analítica de Carl Jung, fue una influencia fundamental en la ETHZ durante los años 70. Rossi partía de una teoría afín al colectivo intelectual suizo que los arquitectos de la ETHZ pronto comprendieron que debían independizar del contexto italiano, desarrollando su propio método a partir de 1985 con la Analoge Architektur. El valor de la preexistencia de acuerdo a este método incipiente se hallaba en su papel articulador de la continuidad cultural de una comunidad, que Miroslav Sik definió a partir de su concepto de Altneue (literalmente, lo Nuevo-Viejo). La fusión entre lo nuevo y lo viejo era la base de la espontaneidad con la que habían crecido los asentamientos históricamente. Sik consideraba que la continuidad dependía de la comprensión de los patrones preexistentes, con el objeto de mantener su vigencia mediante la incorporación de estrategias contemporáneas, que renovarían su significado sin perder su esencia. La Casa Gugalun en Versam de Zumthor de 1994 supone una aproximación a escala doméstica a este planteamiento. La arquitectura suizo alemana reciente a menudo busca en sus referentes plásticos una manera de explorar ámbitos poco accesibles para la disciplina arquitectónica. El pensamiento arquitectónico basado en la imagen poética se implementa a partir de la tectónica de la construcción, que es el medio para comunicar una idea vertebradora del proyecto de principio a fin. La construcción como medio introduce el concepto clave de la apariencia de la arquitectura, estrechamente relacionado con la filosofía idealista de Friedrich Schiller. La apariencia debe expresar el sentido conceptual de la obra, que los arquitectos suizo alemanes denominan idea, por lo que la construcción no tiene un valor por sí misma, sino en cuanto a la apariencia. La Capilla de Oberrealta de Christian Kerez de 1993 puede ser considerada una obra escultórica en el paisaje, más próxima a las artes plásticas que a la arquitectura. La tensión que surge entre la figura ideal y la pieza sometida a una sutil deformación confiere un carácter dinámico a la composición, que intensifica el efecto perceptivo, de acuerdo a la teoría del pensamiento visual de Rudolph Arnheim. La deformación al servicio de la psicología de la percepción es un fenómeno que caracteriza la arquitectura suizo alemana reciente. El concepto de Forme Forte (forma fuerte) fue introducido por Martin Steinmann para caracterizar el objeto arquitectónico denominado internacionalmente Swiss Box. Este concepto se caracteriza por una predilección por lo monolítico, lo unitario y lo arquetípico. La condición más sustancial de una Forme Forte es, sin embargo, la de configurar un elemento estructurador del entorno. Tanto la base morfológica de una Forme Forte, como su capacidad para estructurar el lugar, se corresponden con los conceptos de arquetipo y monumento de la teoría de Rossi. La tesis explora el sentido de la deformación en la producción suizo alemana reciente, a partir de la Escuela de Paspels de Valerio Olgiati de 1998 y la Torre Roccolo de Villa Garbald de Miller&Maranta de 1998. La teoría tectónica de Gottfried Semper y la razón de la forma de Adolf Loos constituyen el sustrato teórico, que relaciona la actividad existencial de habitar con la materialidad de la arquitectura suizo alemana reciente. La teoría tectónica de Semper fundamenta las revisiones posteriores de los sistemas constructivos tradicionales suizo alemanes. Esta influencia sirvió como base a la vanguardia suiza de la Neues Bauen, que desarrolló un racionalismo funcionalista durante las décadas de 1920 y 1930, que constituye una gramática de base no simbólica. Esta gramática constituye el fundamento de la transición del orden clásico a la materialidad como instrumento compositivo durante la segunda mitad del siglo XX, consolidando el concepto de la base material de la forma. La revisión de la tradición regionalista y racionalista llevada a cabo por la generación de arquitectos suizo alemanes de la década de 1950 y 1960, constituyó una investigación lingüística sustancial. Rudolph Olgiati es la figura determinante de este periodo. La revisión de esta investigación se codificó en clave estructuralista durante los años 70 en la ETHZ, influenciada por la presencia de Roland Barthes como profesor invitado. Esta revisión constituyó la base de la articulación tectónica propiamente suizo alemana todavía vigente, como ilustra expresamente la obra de Burkhalter&Sumi en esta tesis. La obra de Gion Caminada en Vrin entre 1995 y 2002 aporta una intensa investigación sobre el Strickbau, que implementa una y otra vez variaciones sobre un sistema tradicional, ilustrando las infinitas posibilidades que ofrece un lenguaje, paradójicamente limitado por los medios disponibles en un entorno alpino aislado. Para terminar Jürg Conzett es el ingeniero con el que han desarrollado sus proyectos la mayoría de los arquitectos en el entorno de los Grisones, formado durante 8 años con Zumthor y colaborador habitual de Caminada entre otros. Conzett es el referente que relaciona la ingeniería con la arquitectura en el ámbito de esta tesis, imprescindible en el contexto de esta investigación. ABSTRACT The Alpine setting of Grisons has been a laboratory for architectural experimentation with an approach forged in the 1970s from various sources in the Swiss Federal Institute of Technology in Zurich (ETHZ). This method has produced a uniquely German-Swiss theoretical discourse over the past three decades. Tradition continues to be a cultural value for Grisons, a region committed to continue linking its architecture with the region’s history and landscape. The specificity of the German-Swiss environment is obvious, but beyond its characteristic features, there is a common denominator that gives these settings a silent unity: it is an idea of building. The phenomenon of Grisons is geographic in its specific location, but it shares the theoretical basis of the rest of the new German-Swiss architecture. This thesis transversely delves into the conditions that have shaped this common path up to the present, just as German-Swiss architecture is going through a time of generational change. In this thesis, Märkli Peter's work constitutes a paradigm of the German-Swiss will to uphold the cultural and architectural continuity of the region, exemplifying an attitude of shared resistance to the globalized world. The thesis is structured around eight recent projects carried out by German-Swiss architects in the Alpine region of Grisons. These projects represent the trajectory of twentieth century German-Swiss architectural history, as well as the architectural phenomenon that has taken place in the environs of Grisons over the past three decades. Through these projects the thesis analyzes the most relevant theoretical, artistic and philosophical references that are synthesized in the works, as well as their architectural references and the transcendental dimension of the materials in which Swiss culture is rooted: wood, stone and concrete. The artistic avant-garde, together with Modernism and the humanistic and regional movements that occurred during the last century, set the stage for present-day German-Swiss architectural sensitivity, which emerges from a complex web of relationships established between the Swiss and international panorama. This same theoretical background and experience underlies all of the German-Swiss territory in general, so associating it through this thesis to a particular context allows the description of a specific embodiment of this debate, within the unique environment of Grisons. The methodological approach to analyzing the projects was phenomenological: direct experience is the main substrate underpinning the focus of the thesis. Field work was not limited to visiting the projects featured in the thesis, but rather encompassed the most important works of recent German-Swiss construction in the Grisons in order to gain some degree of perceptual sensitivity to the uniqueness of its territorial identity. The present paper puts special emphasis on the works of Peter Märkli and Peter Zumthor, who share the formal classicist perspective of the German-Swiss context but stand on opposite sides of the philosophical spectrum with regard to the notion of materiality and the nature of space, which they conceive as systematic or fluid, respectively. The two projects that establish the boundaries of the time period 1992–2004 explored by this research represent two key milestones. The Museum La Congiunta in Giornico, by Peter Märkli, was built in 1992 and quickly established itself as an architectural icon of German-Swiss reductionism. This paradigm of conceptual and constructive synthesis began to take shape in the 1930s under the banner of Konkrete Kunst (Concrete Art), led by Max Bill. The only genuinely Swiss artistic movement of the twentieth century, Konkrete Kunst was characterized by the artistic values of precision, rigor, rationalism and abstraction, sentiments that were very close to the German-Swiss tradition. Secondly, the project for the rehabilitation of Villa Garbald and the construction of the Roccolo Tower in Castasegna, conducted by Miller&Maranta in 2004, represented the consummation of the Analoge Architektur, which was the first truly Swiss architectural movement, spearheaded in the 1980s by Miroslav Sik. The Deutscher Tendenza is a little-known period of recent German-Swiss history, represented by the important figure of Peter Zumthor. The projects that Zumthor led between 1979 and 1985 are part of a period when Italian Neo-Rationalism exercised a profound influence on the architect, as illustrated by the Churwalden School, circa 1983. Recent German-Swiss architecture systematically explored the compositional systems of the artistic avant-garde and Modernism, beyond its specific formal aspects. The second phase of Zumthor's work, between 1985 and 1996, is characterized by the transfiguration of the free plane, neoplastic compositional system developed by De Stijl, a plane that thickened until it became the box articulating fluidity from the spatial sequence. Zumthor's formalism in this phase prioritizes the compositional scheme, consisting of a regular perimeter in which the boxes that -like Mondrian’s colored surfaces- arrange the space around it. Zumthor’s Masans Residence, circa 1993, is a canonical project of this compositional system, which culminates in the radial pattern of the Therme Vals, circa 1996. The poetic image became the appropriate language of thought for German-Swiss architecture, which invited a nonverbal reflection inspired by a few fundamental archetypes. The architects of Ticino sought, through the Italian Tendenza of the 1970s, an alternative to the unsustainable territorial model that was destroying their cultural landscape. Some of these architects began to teach during that decade at ETHZ, and naturally they transmitted their unease to their students. These architects also introduced Aldo Rossi, one of the leading representatives of the Tendenza, to the school. Rossi’s analogue method, based on the analytical psychology of Carl Jung, was a major influence on the ETHZ during the 1970s. Rossi’s theoretical grounding was very much in tune with Swiss intellectualism, and it did not take long for architects from ETHZ to realize that they should break away from the Italian context, developing their own method from 1985 on with the Analoge Architektur. The value of the pre-existing conformity of this emerging method, stemmed from its role in facilitating the cultural continuity of a community, which Miroslav Sik defined in his concept of Altneue (literally, Old-new). This fusion of old and new was the basis for the spontaneity with which settlements had historically grown. Sik considered that continuity depended on understanding the existing patterns and sustaining their relevance through the incorporation of contemporary strategies, which would renew their meaning without losing their essence. Zumthor’s Gugalun House in Versam, circa 1994, is a domestic-scale approach to this philosophy. Modern German-Swiss architecture often looks to its references in visual art for a way to explore areas that are normally inaccessible to the architectural discipline. Architectural thinking based on the poetic image is achieved through a building’s tectonics, which communicate the core idea of a project from start to finish. The understanding of construction as a medium introduces the key concept of the appearance in architecture, closely related to the idealistic philosophy of Friedrich Schiller. The appearance should express the conceptual meaning of the work, which German-Swiss architects call the idea, so that the building does not have value in and of itself, but only in terms of its appearance. The Oberrealta Chapel by Christian Kerez, circa 1993, can be considered a sculpture in the landscape, closer to the visual arts than to architecture. The tension that arises between the ideal figure and the piece subjected to a subtle deformation confers a dynamic character onto the composition, intensifying the perceptual effect, according to Rudolf Arnheim’s theory of visual thought. The deformation in the service of the psychology of perception is a phenomenon that characterizes recent German-Swiss architecture. Martin Steinmann introduced the Forme Forte (Strong Form) concept to describe the architectural object known internationally as the Swiss Box. This concept is characterized by a predilection for all things monolithic, unitary and archetypal. The most substantial condition of a Forme Forte, however, is the configuration of a structuring element in the environment. Both the morphological basis of a Forme Forte and its ability to frame the place, correspond to the concepts of archetype and monument put forward by Rossi’s theory. The present thesis explores the sense of deformation in recent German-Swiss production, based on the School of Paspels by Valerio Olgiati, circa 1998 and the Roccolo Tower in Villa Garbald, by Miller&Maranta, circa 1998. Gottfried Semper’s tectonic theory and Adolf Loos’s reason for form constitute the theoretical foundation that links the existential activity of dwelling to the materiality of recent German-Swiss architecture. Semper’s tectonic theory laid the foundation for subsequent revisions of the German-Swiss traditional building systems. This influence was the basis for the Swiss avant-garde of Neues Bauen, which developed a functional rationalism during the 1920s and 30s that served as a non-symbolic grammatical foundation for the transition from classical order to materiality as a compositional tool. During the second half of the twentieth century, this architectural grammar helped consolidate the concept of the material base of the form. The revision of the regionalist and rationalist tradition, carried out by the generation of German-Swiss architects of the 1950s and 60s, constituted a substantial linguistic investigation. Rudolph Olgiati is the key figure of this period. The research was codified in terms of structuralism in the 1970s in ETHZ and influenced by the presence of Roland Barthes as a visiting professor. This revision was the basis of the uniquely German-Swiss tectonic design still in use today, as specifically illustrated by the work of Burkhalter & Sumi in this thesis. Gion Caminada's work in Vrin between 1995 and 2002 offers an extensive study on the Strickbau, which implements variations on a traditional system again and again, illustrating the endless possibilities of a language that paradoxically seems limited by the available resources in a remote Alpine setting. Finally, Jürg Conzett is the engineer with whom most architects in the Grisons region have developed their projects. Trained under Zumthor for 8 years, and a regular collaborator of Caminada, among others, Conzett is the reference point linking engineering with architecture in this thesis, essential in the context of this research.

Segregating the functions of human hippocampus

It is now accepted that hippocampal lesions impair episodic memory. However, the precise functional role of the hippocampus in episodic memory remains elusive. Recent functional imaging data implicate the hippocampus in processing novelty, a finding supported by human in vivo recordings and event-related potential studies. Here we measure hippocampal responses to novelty, using functional MRI (fMRI), during an item-learning paradigm generated from an artificial grammar system. During learning, two distinct types of novelty were periodically introduced: perceptual novelty, pertaining to the physical characteristics of stimuli (in this case visual characteristics), and exemplar novelty, reflecting semantic characteristics of stimuli (in this case grammatical status within a rule system). We demonstrate a left anterior hippocampal response to both types of novelty and adaptation of these responses with stimulus familiarity. By contrast to these novelty effects, we also show bilateral posterior hippocampal responses with increasing exemplar familiarity. These results suggest a functional dissociation within the hippocampus with respect to the relative familiarity of study items. Neural responses in anterior hippocampus index generic novelty, whereas posterior hippocampal responses index familiarity to stimuli that have behavioral relevance (i.e., only exemplar familiarity). These findings add to recent evidence for functional segregation within the human hippocampus during learning.

Inferring identify from DNA profile evidence.

The controversy over the interpretation of DNA profile evidence in forensic identification can be attributed in part to confusion over the mode(s) of statistical inference appropriate to this setting. Although there has been substantial discussion in the literature of, for example, the role of population genetics issues, few authors have made explicit the inferential framework which underpins their arguments. This lack of clarity has led both to unnecessary debates over ill-posed or inappropriate questions and to the neglect of some issues which can have important consequences. We argue that the mode of statistical inference which seems to underlie the arguments of some authors, based on a hypothesis testing framework, is not appropriate for forensic identification. We propose instead a logically coherent framework in which, for example, the roles both of the population genetics issues and of the nonscientific evidence in a case are incorporated. Our analysis highlights several widely held misconceptions in the DNA profiling debate. For example, the profile frequency is not directly relevant to forensic inference. Further, very small match probabilities may in some settings be consistent with acquittal. Although DNA evidence is typically very strong, our analysis of the coherent approach highlights situations which can arise in practice where alternative methods for assessing DNA evidence may be misleading.

The role of the social environment in non-suicidal self-injury among LGBTQ youth: A mixed methods study

Non-suicidal self-injury (NSSI), such as cutting and burning, is a widespread social problem among lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth. Extant research indicates that this population is more than twice as likely to engage in NSSI than heterosexual and cisgender (non-transgender) youth. Despite the scope of this social problem, it remains relatively unexamined in the literature. Research on other risk behaviors among LGBTQ youth indicates that experiencing homophobia and transphobia in key social contexts such as families, schools, and peer relationships contributes to health disparities among this group. Consequently, the aims of this study were to examine: (1) the relationship between LGBTQ youth's social environments and their NSSI behavior, and (2) whether/how specific aspects of the social environment contribute to an understanding of NSSI among LGBTQ youth. This study was conducted using an exploratory, sequential mixed methods design with two phases. The first phase of the study involved analysis of transcripts from interviews conducted with 44 LGBTQ youth recruited from a community-based organization. In this phase, five qualitative themes were identified: (1) Violence; (2) Misconceptions, Stigma, and Shame; (3) Negotiating LGBTQ Identity; (4) Invisibility and Isolation; and (5) Peer Relationships. Results from the qualitative phase were used to identify key variables and specify statistical models in the second, quantitative, phase of the study, using secondary data from a survey of 252 LGBTQ youth. The qualitative phase revealed how LGBTQ youth, themselves, described the role of the social environment in their NSSI behavior, while the quantitative phase was used to determine whether the qualitative findings could be used to predict engagement in NSSI among a larger sample of LGBTQ youth. The quantitative analyses found that certain social-environmental factors such as experiencing physical abuse at home, feeling unsafe at school, and greater openness about sexual orientation significantly predicted the likelihood of engaging in NSSI among LGBTQ youth. Furthermore, depression partially mediated the relationships between family physical abuse and NSSI and feeling unsafe at school and NSSI. The qualitative and quantitative results were compared in the interpretation phase to explore areas of convergence and incongruence. Overall, this study's findings indicate that social-environmental factors are salient to understanding NSSI among LGBTQ youth. The particular social contexts in which LGBTQ youth live significantly influence their engagement in this risk behavior. These findings can inform the development of culturally relevant NSSI interventions that address the social realities of LGBTQ youth's lives.

Once Upon a Time in Therapy: Crafting Therapeutic Narratives to Help Familiarize Children with the Therapeutic Process.

Young children often harbor misconceptions about psychotherapy and the role of psychologists. These misconceptions are ignited by rumors and misinformation that are provided to the child by a variety of sources and can compromise both the effectiveness of therapy and the therapeutic dyad. In this paper we explore how recent trends in patient engagement in child psychotherapy, cultural dynamics between patients and practitioners, and children's lack of knowledge surrounding mental health services can negatively impact therapy. Wednesday Afternoons with Dr. J. (WADJ) is a whimsical fictional therapeutic narrative created to inform children about aspects of the therapeutic process while providing adults with tangible structure surrounding how to talk to children about mental healthcare. The advantages of utilizing this narrative to prime children for therapy are discussed, as are methods for promoting the narrative to the greater community.

Save the Planet - Buy Organic: The Role of Consumers in the Sustainable Agricultural Movement

The severity of the environmental situation in agriculture is described. Progress made so far is then listed and critiqued. Misconceptions that sustainable agriculture cannot produce as much food as industrial agriculture, as well as the false impression that sustainably-produced foods must cost more are discussed. In conclusion, the only force strong enough to convince farmers to switch to sustainable practices is the consumer. Advertisements and educational campaigns will inform consumers about industrial agriculture. The shift in demand for sustainable goods will eventually cause prices to fall, allowing more consumers to purchase these formally expensive goods. This process will make a sustainable agricultural revolution possible and profitable.

PHORA: a system to solve the anaphora in Spanish

In this paper we present a whole Natural Language Processing (NLP) system for Spanish. The core of this system is the parser, which uses the grammatical formalism Lexical-Functional Grammars (LFG). Another important component of this system is the anaphora resolution module. To solve the anaphora, this module contains a method based on linguistic information (lexical, morphological, syntactic and semantic), structural information (anaphoric accessibility space in which the anaphor obtains the antecedent) and statistical information. This method is based on constraints and preferences and solves pronouns and definite descriptions. Moreover, this system fits dialogue and non-dialogue discourse features. The anaphora resolution module uses several resources, such as a lexical database (Spanish WordNet) to provide semantic information and a POS tagger providing the part of speech for each word and its root to make this resolution process easier.

Adsorbent density impact on gas storage capacities

In the literature, different approaches, terminologies, concepts and equations are used for calculating gas storage capacities. Very often, these approaches are not well defined, used and/or determined, giving rise to significant misconceptions. Even more, some of these approaches, very much associated with the type of adsorbent material used (e.g., porous carbons or new materials such as COFs and MOFs), impede a suitable comparison of their performances for gas storage applications. We review and present the set of equations used to assess the total storage capacity for which, contrarily to the absolute adsorption assessment, all its experimental variables can be determined experimentally without assumptions, ensuring the comparison of different porous storage materials for practical application. These material-based total storage capacities are calculated by taking into account the excess adsorption, the bulk density (ρbulk) and the true density (ρtrue) of the adsorbent. The impact of the material densities on the results are investigated for an exemplary hydrogen isotherm obtained at room temperature and up to 20 MPa. It turns out that the total storage capacity on a volumetric basis, which increases with both, ρbulk and ρtrue, is the most appropriate tool for comparing the performance of storage materials. However, the use of the total storage capacities on a gravimetric basis cannot be recommended, because low material bulk densities could lead to unrealistically high gravimetric values.
