Byggnaden letar i landskapets gömda sidor och tar upp en glänta som blir hjärtat av projektet. Skolan är en plats som borde vara upptäckt steg för steg, och detta borde öka kreativiteten. Den fungerar som ett hjärta, där cirkeln blir en symbol för interaktion och rörelse i alla olika delar av programmet och omgivningen. Byggnaden har sitt hjärta där den befintliga gläntan fins. Där finns de yngre barnen, matsalen som riktar sig utåt. En ny, större glänta är byggt för de större barnen. Den fungerar som en förbindelse mellan samhället och skolan. Den stora cirkeln aktiverar programmet och tar barnen genom alla delar av programmet. Det skulle bli en spännande upptäcktsresa att ta sig från klassrummet till matsalen och efter till biblioteket eller skolgården. Klassrummen får en artikulerad form som uppmuntrar iden om att alla borde hitta sin egen plats och skolan borde vara en plats för alla. Alla ateljéer är placerade i relation med skolgården, öppna mot en aula som kan sträcka sig mot utsidan, där barn kan komma lätt till stora gläntan, till skolgården,därifrån kan de bli sedda och uppskattade.
The building is searching for the site’s existing landscape with it’s forests and an existing hidden glade that becomes the core of the project. The school is a place which is meant to be discovered step by step, in order to increase the creativity. And it acts like a heart, where the circle becomes a symbol for interaction and movement through the parts of the programme and the surroundings. The building has its heart where the existing glade exists.There are the smaller children, the kindergarden and the dining room which are directed outward. A new , bigger glade is built for the children from the upper classes. This acts also as a social act between the society and the school. The big circle activates the place and takes the children through all parts of the program. There will be an challenging investigation to move from the classrooms to the dining room and then to the school garden or the workshops. The classrooms take an articulated form that also encourages the idea of that everyone should find her/his own place and provides a place for everyone. The workshops which are located on the ground floor open up to room where they can extend to the exterior and where the children can work and have acces to the outside and where they can be seen and appreciated.

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1993.
Includes bibliographical references (leaves 96-98).
This thesis addresses the published writing, lectures and interviews of Louis I. Kahn between 1931 and 1974. It attempts to map the elaboration and unfolding of meaning that occur in four of his major concepts: Form and Design, realization, expression and Silence and Light. His textual production is aimed at trying to understand the nature of architecture and its beginnings. This interest leads him into ever widening fields of inquiry into the nature of nature, the nature of man and the nature of beginnings. Most of his concepts can be reduced to a polarity of the measurable and the unmeasurable. His thinking to has two distinct phases: in the first period, 1931 to 1960, he focuses on the tangible concerns of the nature of architecture; in the second phase, from 1960 to 1974, he investigates its more spiritual aspect. The premise of the thesis is that Kahn's writing is cryptic only insofar as one does not understand his particular meanings and definitions for words. The paper traces the continual transformation of specific concepts and their meaning and shows their remarkable consistency. It also demonstrates how Kahn achieves clarity through a strategy of differentiation. Kahn's underlying motivation is to understand the unmeasurable so that he can embody a sense of the eternal in his architecture.

The philosopher Heraclitus has been renowned for a great amount of time. Despite that fact the remaining fragments of his work have just recently been assembled to the composed form they have today. Among these fragments there are a couple of terms that stands out amongst others; one of them is the term logos. The main focus of this thesis is devoted to the mystery and usage of the term logos, which comes into a great display in fragment number 50. The ambition of the thesis is to evaluate and compare three interpreters’ readings of Heraclitus while having a close focus on his usage of the word logos in fragment 50. One of these interpreters, Martin Heidegger, may have the most radical reading of Heraclitus’ logos among the three. Because of his philosophical standpoint he interprets Heraclitus in a way which has never been done before. The other two do not have Heidegger’s phenomenological perspective, by which Heidegger broadens our understanding of Heraclitus fragments, which isn’t as the thesis will show unproblematic. The other two interpreters G.S. Kirk and Charles H. Kahn both do a thorough reading and translation of all the fragments, whereas Heidegger is more selective in his reading of the fragments. Heidegger doesn’t have the same intention in his interpretation as Kirk or Kahn; therefore may he be said to be more selective in his reading of Heraclitus. While Kirk and Kahn depict a more naturalistic ethic tendency in Heraclitus, Heidegger illustrates an ontological tendency which speaks about being and its’ constitution and expression as such. At the end of the thesis there is an analytic part which compares and investigates the possible difficulties in comparing the three readings. The thesis acknowledges the possibility of impossibility in ever understanding the extent of Heraclitus thoughts around logos; the three interpreters hopefully show the scope of understanding Heraclitus’ thoughts around this term.

This thesis investigates the relationship between architecture, Romanticism, American Transcendentalism, myth, and religious mysticism in the ideas of the American architect, Louis Kahn. Part One builds a chronology from Hermeticism and Jewish mysticisms into German Romanticism and how they played a role in the world of Kahnâ s parents shortly before his birth. The first chapter looks at mysticism and how it resonates with Kahnâ s descriptions of silence and light. The second chapter outlines the transition from rational aesthetics during the German Enlightenment into German Romanticism. This exposes the beginning of organicism as a way of seeing the world as a growth from a mythic image towards a physical manifestation made by artists and poets. In chapter three, the ideas from Romanticism inspire a philosophical and political movement for independence and cultural expression in the native region of Kahnâ s parents. Part Two concentrates on the American approach to Romanticism via Transcendentalism and how Transcendentalism influenced Kahnâ s childhood education in Philadelphia. It shows how the ideas of German Romanticism influenced English literature and criticism, especially Coleridgeâ s theories of organicism and literary criticism. Chapter four presents how the American Transcendentalists correlated the mind and imagination to an organism. In chapter five, we see how Transcendentalismâ s aesthetic theory influenced the Public Industrial Arts School of Philadelphiaâ s approach to teaching art. Louis Kahn attended this school. The final chapter deciphers Kahnâ s ideas, such as â form and design,â â material as spent light,â â measurable and unmeasurable,â â law and rule,â â order,â and â nature.â Within the framework of Romanticism and American Transcendentalism, these ideas become intelligible and an enriching approach to understand his architecture.

Louis I. Kahn - Architectural History as Mediation investigates the work of one of the most active architects of the 20th century who has been acknowledged by scholars as a modern thinker and architect, but is also known for his interest in history, and the clear references to historical precedents in his work. In studying Kahn's architectural training, writings, readings, travel experience, personal contacts, the context in which he practiced, and through investigating his personal drawings and two of his design projects, Kahn's layered approach to architectural history is unveiled.In describing the architectural context of Kahn's education and work, this thesis deals with important aspects of architectural thought and making, which Kahn was exposed to, and sheds light on the motivation behind Kahn's unique philosophical quest. When investigating Kahn's drawings done during his travelling experiences, the manner in which he embodied historical sites becomes apparent. Studying archival material it tracks Kahn's studies of architectural references, and analyzing his architectural drawings and designs for the Dominican Motherhouse of St. Catherine de Ricci, Media, Pennsylvania (1965-1969, un-built) and the Hurva Synagogue in the Old City of Jerusalem (1967-1974, un-built) it exemplifies the poetic references made by his projects to historical precedents - all while concentrating on hermeneutic and phenomenological concepts relating to perception, memory and understanding of the past.Thus, through Kahn, this dissertation addresses the contextual debate regarding the use of historical references in modern architecture from the 18th century up until the postmodern era, and deals with the importance of continuity of references in the age of fragmentation. Louis I. Kahn - Architectural History as Mediation reveals the possible intricate potential lying in the consideration of tradition and history in modern architecture, and sheds light on suitable endeavors in architectural thought and making which at once integrate historical references and promote originality and progress - both fundamental for innovative poetic architectural expressions.
Dans Louis I. Kahn – L'histoire de l'architecture comme médiation, on explore le travail de l'un des architectes le plus actifs du 20e siècle. Il a été reconnu par les intellectuels pour son rôle d'architecte et de penseur moderne, ainsi que pour ses recherches en histoire et ses références aux œuvres historiques importantes. En étudiant Kahn et son éducation, sa formation en architecture, ses écrits, lectures, voyages, contacts personnels, le contexte dans lequel il travaillait, en plus d'examiner ses dessins personnels et deux de ses projets de design, on comprend son approche de l'architecture sous plusieurs angles. En décrivant le contexte dans lequel Kahn a été éduqué et dans lequel il a pratiqué son métier, la thèse traite d'importants aspects de la pensée et pratique architecturale auxquels Kahn a été exposé, dévoilant ainsi les motivations derrière sa quête philosophique unique. En examinant les dessins de Kahn, la manière dont il incarne les sites historiques qu'il a vus durant ses voyages devient apparent. À travers l'étude du matériel d'archives, la trace des références architecturales que Kahn a étudiées devient visible. Ainsi, dans ses dessins et la conception architecturale pour le Dominican Motherhouse de St. Catherine de Ricci, Media, Pennsylvanie (1965-1969, jamais construit) et le Hurva Synagogue dans la vieille ville de Jérusalem (1967-1974, jamais construit), les références poétiques aux œuvres historiques que sont ses projets sont clairement illustrées, tout en soulignant des concepts herméneutiques et phénoménologiques en relation avec la perception, la mémoire et la compréhension du passé. Par conséquent, à travers Kahn, cette thèse examinera le débat contextuel concernant l'usage de références historiques dans l'architecture moderne du 18ième siècle jusqu'au postmodernisme, et abordera l'importance de la continuité des références dans l'âge de fragmentation. Louis I. Kahn – L'histoire de l'architecture comme moyen de médiation dévoilera le complexe potentiel dans l'étude de la tradition et l'histoire de l'architecture moderne. Elle éclairera les efforts acceptables dans la pensée et la pratique de l'architecture qui intègrent des références historiques et promeuvent l'authenticité et le progrès – deux éléments fondamentaux de l'expression architecturale poétique et innovatrice.

Les langages synchrones ont été fondés pour modéliser et implémenter les systèmes réactifs temps-réels critiques. Avec la complexité toujours croissante des systèmes contrôlés, la vitesse d'exécution devient un critère important. Nous sommes donc à la recherche d'une exécution parallèle, combinant efficacité et sûreté.Les langages synchrones ont toujours intégré la notion de parallélisme, mais ce, pour l'expressivité de la modélisation. Leurs compilations visent principalement les circuits ou la génération de code séquentiel. Tous ont une sémantique formelle, qui rend possible la distribution correcte du code. Mais la préservation de cette sémantique peut être un obstacle à l'efficacité du code généré, particulièrement s'il est nécessaire de préserver une notion d'instant global au système.Le modèle sémantique qui nous intéresse est celui des réseaux de Kahn. Ces réseaux modélisent des calculateurs distribués, communiquant au travers de files de taille non bornée. Dans ce cadre, la distribution ne demande aucune communication ni synchronisation supplémentaire. En considérant l'histoire des files de communication, la sémantique de Kahn permet de s'abstraire de l'exécution effective, tout en garantissant le déterminisme du calcul. Pour cela, chaque nœud du réseau doit avoir une sémantique fonctionnelle continue.Le langage que nous développons est Heptagon, un langage synchrone fonctionnel du premier ordre, déscendant de Lustre. Son compilateur est un prototype universitaire, apparenté à l'outil industriel Scade. Grâce à sa sémantique de Kahn, la distribution d'un programme Heptagon ne pose pas de question, son efficacité beaucoup plus.L'efficacité requiert de minimiser les synchronisations. Cela revêt deux aspects non indépendants. Avoir un découplage suffisant des calculs : il y a des délais dans les dépendances entre calculs. Avoir une granularité importante des calculs : un fort ratio temps de calcul sur fréquence de communication. Or la sémantique synchrone et les horloges d'un programme Heptagon reflètent exactement l'inverse. Elles permettent au programmeur de se contenter d'un découplage d'un instant et à chaque instant, au maximum une valeur est calculée. De plus, les instants sont typiquement courts, pour assurer que le système réagit rapidement.Des précédents travaux sur le sujet, nous tirons deux constats.Le premier est que nous souhaitons le contrôle du parallélisme par le programmeur, directement dans le code source. Il doit pouvoir maîtriser à quels instants il y a communication ou synchronisation. La solution que nous proposons dans ce manuscrit est l'utilisation des futures dans Heptagon. Ils fournissent ce pouvoir au programmeur, tout en restant des annotations qui peuvent être supprimées sans changer la sémantique dénotationnelle du programme.Le deuxième constat est que la question de la granularité des calculs est une question profonde, touchant en particulier aux questions de dépendance de données, de choix des horloges et de compilation modulaire. Heptagon, comme ses parents, restreint les réseaux de Kahn qui peuvent être écrits, de telle sorte que ces trois questions se traitent séparément. Pour mieux comprendre le lien entre ces éléments, nous revenons aux réseaux de Kahn. Notre principal résultat est la définition de la sous-classe des réseaux ordonnés réactifs. Ceux-ci sont les seuls pour lesquels nous pouvons décrire modulairement le comportement avec des horloges, sans restreindre les contextes d'appels. Ces réseaux ont une signature d'horloge en forme normale, qui maximise la granularité. Pour l'exprimer, nous introduisons les horloges entières, décrivant la communication de plusieurs valeurs en un seul instant. Nous appliquons ensuite nos résultats pour voir sous un nouveau jour Heptagon, Signal, les politiques des objets de Lucid Synchrone, mais aussi proposer une analyse pleinement modulaire de Lucy-n langage synchrone le plus fidèle aux réseaux de Kahn
Synchronous languages are used to program critical reactive systems. Today, systems require to find a way to execute them safely and in parallel. Parallelism has always been part of synchronous langages, but for modeling purpose. Their formal semantics allow to distribute them, but preserving the semantics may be ressource costly and prevent good parallel execution.The Kahn networks model is of great interest. It models distributed computers, communicating through unbounded FIFOs, ensuring that the computed values are deterministic, without any need of added synchronization.We develop the langage Heptagon, a first order functional synchronous son of Lustre.The compiler is an academic prototype of the industrial tool Scade. Thanks to its Kahn semantics, it can be distributed. In order to be efficient, one need to maximize the decoupling of computations and maximize the computation granularity. However, synchronous langages allow for very tight computation coupling and usually require thin computation granularity to ensure reactivity of the system.We opt for two research directions. The first one is to give the control of the execution parallelism to the programer. To this mean, we add futures to the source langage Heptagon. They provide control over starting and end of parallel computations, while preserving the functional semantics. Moreover, we provide a compilation for embedded systems, using statically allocated memory. The second one is to study Kahn synchronous semantics to understand data dependencies and maximize granularity of the computations. This touches deeply to the synchronous languages, mixing the usually separated questions of causality and clock calculus. We define the class of reactive ordered Kahn networks. They are the one which may be modularly compiled and whose behavior may be expressed with a clock signature. Moreover, we show that their is a normal form for this signature, maximizing the granularity of the network. To express it, we extend clocks to integer clocks. Then we come back to the synchronous languages we know to understand how to use it. The result is fully used and explained on Lucy-n, the synchronous language closest to Kahn networks

A dissertação apresenta a visão de história que compõe o método de especulação e planejamento do futuro exposto no livro O ano 2000, de 1967, escrito por Herman Kahn e Anthony J. Wiener. O trabalho consiste na investigação das idéias e conceitos empregados no método, assim como nos resultados gerais da especulação e do planejamento do futuro, visando expor as influências de outros autores, idéias e conceitos, além dos diversos contextos que se articulam na obra. A dissertação visa mostrar como se constituiu o pensamento futurista de Kahn e Wiener em relação à história, a saber, uma visão progressista, porém não mais linear e como um produto da razão inerente ao homem, mas como um progresso que é conquistado a cada momento do presente pelo esforço humano em planejar o futuro. A história aparece assim como um desenvolvimento macro-histórico, que explica os desenvolvimentos passados e as possibilidades futuras, e, ainda, como um conjunto de exemplos heurísticos para pensar como as possibilidades futuras podem se manifestar factualmente. A pesquisa conclui que o pensamento futurista é um objeto de estudo muito rico para os historiadores por sua apropriação da história, pela representatividade como fenômeno histórico e por sua abrangência como parte da vida contemporânea.
This dissertation approaches the view of history embedded in the method of future speculation and planning set out in the book The year 2000, written in 1967, by Herman Kahn and Anthony J. Wiener. This work consists in investigating the ideas and concepts in the method, as well as in overall results of future speculation and planning, in order to expose the influences of other authors, ideas and concepts and the various contexts articulated in the book. We here try to show how the futurist thinking of Kahn and Wiener understood history, namely, a view of progress however no longer linear or a product of a reason inherent to man, but a progress achieved every moment by human effort in planning the future. Thus, history appears as a macro-historical development that explains past developments and future possibilities, and also as a set of heuristic examples to consider how future possibilities can manifest factually. The research concludes that futurist thinking is a valuable study object to historians for its appropriation of history, for its importance as a historical phenomenon and for its significance as part of the contemporary life.

Includes bibliographical references (leaves 66-68).
The Aga Khan Award for Architecture (AKAA) is an architectural award instituted by His Highness Karim Aga Khan to recognize the achievements of architects, planners, and community organizations that have contributed to architecture in the Muslim world. The scope of the AKAA enterprise is vast and informed by a vision that builds on establishing a critical foundation for the project of rethinking architecture for Muslim societies. That vision began with a challenge set by His Highness which simply asked, "What is the physical environment that Muslims should seek for themselves and for future generations in their homelands?" This question set into motion a diverse set of activities under the aegis of the Award, one of which was the establishment of a forum for debate, the AKAA seminars, to struggle with the intellectual groundwork needed to confront the challenges of the built environment in Muslim societies. Through a critical review and analysis of the issues raised within these seminars, this thesis examines the intellectual concerns of the AKAA and attempts to show how the formulation of these concerns have evolved over the last two decades. The results of this study show that in attempting to become a voice for issues revolving around the built environment of Muslim societies, the AKAA has generated a mediating discourse that integrates the rich architectural heritage of the Islamic world with the technological advances of modernity. However, as a strategy to deal with the impact of modernity within the Muslim world, the intellectual debate stops short of challenging the social and ideological structures within Muslim societies itself that have contributed to problems related to modernization and its impact on the built environment.

Essa dissertação apresenta um estudo analítico sobre a obra do arquiteto Louis I. Kahn, desde o ponto de vista da sua qualidade espacial, compreendida esta no modo como ocorre a interação entre espaço e usuário. Foram selecionados três edifícios como estudos de caso capazes de representar a síntese evolutiva da concepção de espaço ao longo da obra de Kahn, os quais foram submetidos a uma análise empírica baseada na experiência espacial do observador em movimento, lançando mão de um conjunto de ferramentas no assim denominado método do observador. Os edifícios estudados viabilizam o desenvolvimento de análises que abrangem desde as primeiras obras de Kahn, na década de 1930, até o seu falecimento, em 1974. A análise realizada registra o desempenho dos edifícios em termos de sua legibilidade e funcionalidade, compreendidas como qualidades inerentes ao espaço e ao modo como este condiciona a experiência do usuário, relacionandoas à concepção espacial do edifício. Procura-se ampliar a compreensão dos resultados obtidos à luz da evolução da obra teórica do autor, traçando relações de causa e efeito entre esta e os fenômenos registrados na realidade concreta dos edifícios. O trabalho busca ainda ampliar a compreensão da relação da obra de Kahn com o contexto da produção arquitetônica de sua época, investigando as influências que recebe e as contribuições que oferece, especialmente no que tange à continuidade da arquitetura moderna.
The present dissertation is as an analytical study about the work of architect Louis I. Kahn, focusing on its spatial quality, as funded in the interaction between space and people in motion. Three buildings were selected as case studies in order to capture the evolutionary synthesis of space conception happened during Kahn’s career. Each building was submitted to an empirical scrutiny based upon the spatial experience of a moving observer, using a set of tools named as the “method of the observer”. The buildings investigated are put in relation with other Kahn’s buildings, so allowing the development of an analytical discourse embracing since his first works, in the 1930’s, until his death, in 1974. The analysis registers the performance of the buildings in terms of their legibility and their functionality, both understood as qualities inherent to space and the way they shape the user’s experience, so relating them to the building’s spatial conception. The dissertation intends to enlarge the understanding of the findings by considering the evolution of Kahn’s theoretical work, so bringing cause-effect connections between theory and the registered phenomena in the concrete reality of buildings. Eventually, this study aims to enlarge the understanding of the link between Kahn’s work and the architectural environment of the time, so exploring the influences he received and contributions he gave, especially concerning the evolution of modern architecture.

La thèse porte sur les réseaux de Kahn, un modèle de concurrence simple et expressif proposé par Gilles Kahn dans les années 70, et leur implémentation sur des architectures multi-coeurs modernes, à mémoire partagée. Dans un réseau de Kahn, le programmeur décrit un programme parallèle comme un ensemble de processus et de canaux communicants, reliant chacun exactement un processus producteur à un consommateur. Nous nous concentrons ici sur les aspects algorithmiques et les choix de conception liés à l'implémentation, avec deux points clefs : les garanties non bloquantes et la mémoire relâchée. Le développement d'algorithmes non bloquants efficaces s'inscrit dans une optique de gestion des ressources et de garantie de performance sur les plateformes à ordonnancement irrégulier, telles que les machines virtuelles ou les GPU. Un travail complémentaire sur les modèles de mémoire relâchée vient compléter cette approche théorique par un prolongement plus pratique dans le monde des architectures à mémoire partagée contemporaines. Nous présentons un nouvel algorithme non bloquant pour l'interprétation de réseaux de Kahn. Celui-ci est parallèle sur les accès disjoints : il permet à plusieurs processeursde travailler simultanément sur un même réseau de Kahn partagé, tout en exploitant le parallélisme entre processus indépendants. Il offre dans le même temps des garanties de progrès non bloquant : en mémoire bornée et en présence de retards sur les processeurs. L'ensemble forme, à notre connaissance, le premier système complètement non bloquant de cette envergure : techniques classiques de programmation non bloquante et contributions spécifiques aux réseaux de Kahn. Nous discutons également d'une variante bloquante destinée au calcul haute performance, avec des résultats expérimentaux encourageants
In this thesis, we are interested in Kahn process networks, a simple yet expressive model of concurrency, and its parallel implementation on modern shared-memory architectures. Kahn process networks expose concurrency to the programmer through an arrangement of sequential processes and single-producer single-consumer channels. The focus is on the implementation aspects. Of particular importance to our study are two parameters: lock freedom and relaxed memory. The development of fast andefficient lock-free algorithms ties into concerns of controlled resource consumption and reliable performance on current and future platforms with unfair or skewed scheduling such as virtual machines and GPUs. Our work with relaxed memory models complements this more theoretical approach by offering a window into realistic sharedmemory architectures. We present a new lock-free algorithm for a Kahn process network interpreter. It is disjoint-access parallel: we allow multiple threads to work on the same shared Kahn process network, fully utilizing the parallelism exhibited by independent processes. It is nonblockingin that it guarantees global progress in bounded memory, even in the presence of (possibly infinite) delays affecting the executing threads. To our knowledge, it is the first lock-free system of this size, and integrates various well-known non-blocking techniques and concepts (e.g., safe memory reclamation, multi-word updates, assistance) with ideas and optimizations specific to the Kahn network setting. We also discuss a variant of the algorithm, which is blocking and targeted at high-performance computing, with encouraging experimental results

La thèse étudie les positions successives de Kahn à l'égard de la question de la structure. Elle analyse ce qui apparaît comme un véritable travail d'investigation développé au cours de trente ans de pratique et d'exercice (1944-1974). Les documents permettant de cerner l'implication de Kahn dans les débats contemporains, les rapports qu'il établit avec l'Histoire, les dessins de projet, les maquettes d'étude et les édifices sont examinés en tant que témoignages d'un travail d'architecture et d'une entreprise intellectuelle. L'étude est centrée sur l'analyse comparative des projets, des variantes et des variations de leurs thèmes, qui vise à faire apparaître les déplacements et l'enrichissement de l'approche théorique de l'architecte par les échanges et débats continus avec les ingénieurs et les collaborateurs. Ainsi la pratique de Louis I. Kahn, étudiée à l'aune de la question de la structure, restitue la démarche intellectuelle de l'architecte

Documents that allow to grasp Kahn's implications in contemporary debates and his attitude toward history, his working drawings, study models and buildings are examined as testimonies of a work of architecture as well as of an intellectual undertaking. Centered on the comparative analysis of designs and of variants or variations of their themes, the research aims to demonstrate how the theoretical approach shifts and is enriched by continuous exchange with engineers and collaborators.

Toute architecture est effet d’un sujet/architecte. La psychanalyse peut éclairer la dialectique nouée entre œuvres tangibles et sources subjectives, les trajectoires de Louis Kahn 1901-1974 et Le Corbusier 1887-1965, illustrent cette thèse. L’étude des périodes primordiales et de l’entrée en architecture dessinent les contours d’Un sujet/architecte. Comme divisé, il est vecteur de manifestations de l’inconscient perceptibles dans ses Ecrits essentiels et durant ses voyages initiatiques. Avec la psychanalyse sont relevés des indices de traits psychiques, auxquels sont assujetties les praxis, situant L. Kahn au champ de la névrose et Le Corbusier de la psychose, hors considérations cliniques. L’analyse de leurs projets manifeste chez l’un l’insistance de deux signifiants, lumière et masse, et chez l’autre des images de volumes géométriques, repérables depuis leurs petites enfances. La praxis Kahnienne s’origine d’un fantasme - $$<˃a - où l’objet a conjugue lumière et masse. Le Corbusier, quant à lui, soumit à une lourde pulsion scopique fait de l’architecture « le jeu [. . . ] des volumes assemblés sous la lumière ». L’architecture de L. Kahn associe ses objets causes du désir à d’autres recherchés chez l’Autre. L’usage y passe avant le design, elle est in finissable et établie sur le mode de la condensation. Le Corbusier élabore des standarts - objets universels, mortifiés, destinés à un homme type imaginaire sensible à une jouissance scopique universelle créée par l’assemblage des objets qu’il tient « dans sa poche ». A travers deux sujets/architectes, la psychanalyse met en évidence les enjeux de l’architecture entre esthétique, usages, et pertinence dans la culture. Al architecture is produced by a subject/architect. Psychoanalysis can illuminate the dialectic established between tangible works and the subjective sources, trajectories of Lois Kahn and Le Corbusier (1901-1974, 1887-1965) illustrate this thesis. The study of primordial periods and those of entry into architecture draw the contours of the singularity of the subject as architect. As divided he is the place of manifestations of the unconscious noticeable in his essential writings and during his initiatory journeys. With psychoanalysis are indicated some indices of psychological traits. They influence architectural works and allow situating L. Kahn in the field of neurosis - and Le Corbusier in psychosis. The analysis of their projects is showing in Kahn architecture the insistence of two signifiers - the light and the mass - and in the one of Le Corbusier the images of geometric volumes, identifiable since their childhoods. Kahn’s praxis originates a fantasy - [symbole du dollar]<˃a - where the object a combines the light and the mass. Le Corbusier, meanwhile, submits a heavy scopic drive feels architecture as “game […] of volumes brought together under light. ” The architecture of Louis Kahn combines its own cause’s objects of desire with others found in the Other. The use going on before aesthetics. Le Corbusier develops universals objects, mortified, he calls “standarts”. They must satisfied an imagined man, sensitive to universal scopic enjoyment created by assembling of objects he hold “in is pocket”

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1995.
Includes bibliographical references (p. 110-115).
Kahn's genre of travel sketches offers us a visual basis to map his philosophical meandering. This thesis addresses the sketches produced from Kahn's voyages around the Mediterranean in 1950-51 and 1959 with an aim to understanding the premises that underlie them. During the trips, Kahn conjectured in his graphic oeuvre a dialogical method with the built forms of antiquity. On the one hand, he sought answers to his architectural and epistemological questions to these buildings; at another level, he re-contextualized the buildings in an imagined landscape that would in tum inform his imperatives. The sketches also permit an interesting theoretical commentary as they parallel Kahn's emergence into active architectural career in the fifties. At first encounter, some of them seem to be perplexing, but once extended into the context in which Kahn operated, they reveal an interwoven terrain of concepts that would continuously flower. There is no doubt that in his travel sketches Kahn was fighting a protracted battle about his architecture and that he benefited from the buildings of the past--but mostly at an epistemological level. Kahn raised questions on architecture that could have not been addressed by a formal retrieval of history. In that sense Kahn's travel sketches reappraise and re-propose the lessons of history.

Doutoramento em Arquitectura
Os modelos dos edifícios funcionais do princípio do século XX fundem-se e moldam-se num cruzamento inter-atlântico de influências tecnológicas. De facto, os sistemas de construção em betão armado, com todas as variáveis de experimentação científica, contribuíram para uma estandardização da indústria da construção bem como das práticas profissionais a ela associadas, originando uma corrente de proto-modernidade essencial à formação do espírito moderno. As obras funcionalistas dos primeiros quinze anos do século XX resumem em si práticas profissionais que mais tarde serão negadas pelos mestres do modernismo enquanto parte dos processos da construção moderna, mas cujo “estilo” resultante é por estes celebrado. Constituem-se essencialmente de edifícios fábrica, construídos em betão armado, conjugando níveis de performance e de operacionalidade que resumem a função última a que se destinam. A prática do arquitecto moderno europeu, oferecendo resistências a uma total modernidade consagrada em teoria, permitiu a sobrevivência da arquitectura enquanto prática artística, face a um outro lado da profissão, de carácter mais pragmático e assente no princípio do corporativismo liberal.
Models of functional buildings at the beginning of the 20th Century were embedded and moulded in the inter-Atlantic blending of technological influences. In fact, building systems in reinforced concrete, with all their variables in scientific experiments, helped towards standardizing the building industry as well as the way in which professional activity was undertaken. They thus gave rise to a protomodernity current that was essential in shaping the modern spirit. The functionalist buildings appearing in the first fifteen years of the 20th Century are a testimony of the kind of professional practices that would later be condemned by the masters of modernism, for the part these edifices played in modern building processes, but whose resulting “style” would nevertheless be celebrated by the European masters. They mostly came in the form of factory buildings in reinforced concrete, conjugating levels of performance and operativeness that sought to satisfy the main aim for which they had been built. By offering resistance to the Modernity consecrated in theory, the practice of the modern European architect allowed architecture to survive as an artistic practice, as opposed to a more pragmatic nature of the North American architect.

L’axe principal de ce travail de thèse est de s’intéresser à ce projet visuel dans l’œuvre d’Albert Kahn et d’ouvrir le champ en s’intéressant aux devenirs des films des Archives de la Planète. Pour cela, la thèse s’appuie sur la totalité des archives administratives du Musée Albert Kahn, sur les archives d’Albert Kahn et sur ses nombreux proches, sur les archives départementales et nationales ou encore à travers des enquêtes menés dans les archives de l’INA, des centres d’art et les archives du film. En s’intéressant, dans un premier temps, à la figure kahnienne à travers la construction des discours contemporains ou posthumes de Kahn, la thèse s’oriente dans un deuxième temps vers une analyse du projet visuel kahnien. En s’appuyant sur des penseurs contemporains de Kahn et sur certains de ses écrits, ce deuxième temps tente de comprendre comment les Archives de la Planète sont rendues possibles et en quoi elles s’inscrivent dans une pensée de l’image à la fois globale et spécifique. Enfin, la troisième partie de ce travail explore, premièrement, la « mise en disponibilités » des films des Archives de la Planète en partant de la mort d’Albert Kahn jusqu’au début des années 2000 en s’appuyant sur l’histoire de l’institution muséale et sur ses satellites – comme la « Cinémathèque de Boulogne ». Le deuxième temps de la troisième partie ouvre la réflexion en se concentrant sur les devenirs des Archives de la Planète à travers des études de cas d’appropriations des films kahniens dans des productions extérieures (Chris Marker, Abel Gance, Nicole Vedrès, Frédéric Rossif etc.) et à la télévision
The main approach of this PhD is to focus on the visual project within Albert Kahn’s work and to broaden the scope by studying what will become of the films from the Archives of the Planet. To achieve this goal, the thesis draws on the whole administrative archives of the Albert Kahn Museum, on the archives of Albert Kahn and his numerous relatives, on the departmental and national archives and through investigations conducted in the archives of the INA (the National Institute for Audio-visual Media), art centres and the film’s archives. By first looking at the kahnian figure through the construction of Kahn’s contemporary and posthumous speeches, the thesis then takes a turn towards an analysis of the kahnian visual project. As it draws on thinkers contemporary to Kahn and on some of his writings, this second part attempts to grasp how the Archives of the Planet have been made possible and how they are embedded in a thinking, both global and specific, on images. Finally, the third part of this work first delves into the period when the films of the Archives of the Planet were “made available” from Albert Kahn’s death to the early 2000s, by drawing on the history of the museal institution and its satellites – such as the “Cinémathèque de Boulogne.” The third part then opens up the reflection by focusing on the futures of the Archives of the Planet and, by studying cases of appropriation of the kahnian films in external productions (Chris Marker, Abel Gance, Nicole Vedrès, Frédéric Rossif etc.) and on television

Dans le cadre de l'essor des Etats-Unis comme puissance mondiale, nous étudions dans quelle mesure leur croissanceintellectuelle est favorisée par les transferts d'étudiants dans les deux sens ou d'institutions françaises en Amérique. Parmicelles-ci, une attention toute particulière est donnée à l'Ecole Libre des Sciences Politiques de Paris, dont nous avons dépouilléles archives, recensé les élèves américains depuis sa création jusqu'à la fin de notre période en 1932. Nous montronsl'importance de certains élèves, et étudions les établissements auxquels elle donne naissance en Amérique. Nous expliquons letransfert aux Etats-Unis du Musée Social de Paris. Nous tenons compte des réseaux d'historiens, de géographes,d'économistes, de sociologues et d'autres universitaires français et américains. Nous analysons les étudiants, y compris ceuxprovenant de programmes créés par James Hyde et Albert Kahn, où l'Université Harvard tient une place de choix. Ladétermination de la France à attirer les étudiants étrangers est au détriment de l'Allemagne où la plupart des grandsuniversitaires américains étaient formés. Nous étudions donc à travers une biographie intellectuelle de Jean Jules Jusserand,ambassadeur de France aux Etats-Unis pendant 22 ans, la guerre d'influence que les intellectuels allemands et français selivrent en Amérique, avant et pendant la Grande Guerre
Within the context of the expansion of the United States as a world power, we study the extent to which their intellectualdevelopment is enhanced by bidirectional exchanges of students or transfers from French institutions to America. Amongthose, we take in in-depth look at the Ecole Libre des Sciences Politiques in Paris. Having combed its archives, we could list theAmerican students there, from its founding to the end of our period of study in 1932. We point out the importance of somestudents and study the schools it gave birth to in America. We explain the transfer from the Musée Social or Paris to the U.S..We take into account the networking between French and American historians, geographers, economists, sociologists andother university scholars. We analyze exchange students, including those from programs created by James Hyde and AlbertKahn, with a particular emphasis on Harvard University. France is determined to attract foreign students at the expense ofGermany where the majority of the best American scholars were trained. Therefore, by way of an intellectual biography of JeanJules Jusserand, French ambassador to the U.S. for 22 years, we study the war of influence on American soil between Frenchand German intellectuals, before and during World War I

In 2013, 1% of Medicare reimbursements were withheld from U.S. hospitals, with a proposed cap of 2% in 2017 for redistribution to those hospitals that improve overall care and patient satisfaction. The purpose of this single case study was to explore the engagement strategies that some hospital middle managers used to improve employee performance to increase patient satisfaction. The sample included 4 health care middle managers in 1 hospital in northeast Connecticut. The conceptual framework that grounded this study was Kahn's personal engagement theory. Data were collected via semistructured interviews, participant observations, and review of hospital and public government documents. The process of member checking and methodological triangulation contributed to the study validity. The data were analyzed using Yin's 5-step method of analysis. Themes that emerged from the study were the importance of the role of the manager in fostering employee engagement, implementing explicit communication techniques, assisting employees in role performance, promoting employee wellbeing, commitment to patient care and satisfaction, and providing employees with rewards and recognition. Although this was a single case study, health care managers from other hospitals could benefit from the results of this study. The implications for social change include the potential for hospital managers to implement strategies to improve employees' engagement, thus improving patients' care and satisfaction, and the overall health and wellness of individuals in the community.

Dans cette thèse, nous nous intéressons aux modèles et aux langages pour la programmation d'applications de traitement de flux ayant des contraintes de temps-réel, comme les applications multimédias. Elles manipulent des flots de données infinis, auxquels sont appliquées des opérations successives. Ces systèmes peuvent être représentés par des réseaux de Kahn. Dans ce modèle, des noeuds de calcul s'exécutent de manière concurrente et communiquent à travers des buffers infinis. Son intérêt est d'être déterministe tout en permettant d'exprimer le parallélisme intrinsèque aux applications. Néanmoins, il présente l'inconvénient de ne pas donner de garanties sur l'absence d'interblocage et sur le caractère borné des buffers. Les langages synchrones flot de données fournissent un cadre simple pour la programmation de réseaux de Kahn sans buffers. Ils offrent des garanties fortes comme l'absence de blocage et un besoin en mémoire bornée. La contrepartie de ces garanties est un manque de souplesse dans la composition des flots : celle-ci doit être réalisée sans buffers. Le modèle n-synchrone est une extension du modèle synchrone qui relâche cette contrainte de manière contrôlée. Il permet une composition plus souple, tout en conservant les garanties statiques offertes par les langages synchrones. Nous présentons un langage qui met en oeuvre le modèle n-synchrone. En particulier, nous détaillons les analyses permettant de vérifier statiquement qu'un programme est exécutable avec des buffers bornés et de calculer automatiquement leur taille
In this thesis, we are interested in models and languages to program stream processing applications with real-time constraints, such as multimedia applications. They manipulate infinite data flows, on which they apply successive operations. These systems can be represented by Kahn Process Networks. In this model, computation nodes are executed concurrently and communicate through unbounded buffers. It has the advantage of being deterministic and yet allowing to express the intrinsic parallelism of applications. Nevertheless, it does not guarantee that the system is deadlock free and that it can be executed with bounded memory. Dataflow Synchronous Languages are a simple framework to program Kahn Process Networks without buffers. They offer strong guarantees on memory bounds and absence of deadlocks. The downside of these guarantees is a lack of flexibility in the composition of flows: communication must be done synchronously, that is without buffers. The n-synchronous model is an extension of the synchronous model that relaxes the synchronous constraint in a controlled way. It allows a more flexible composition while preserving static guarantees given by synchronous languages. We present a n-synchronous language and we focus on the analysis which statically checks that a program can be executed with bounded buffers and automatically computes those sizes

On the 15th of May 2011 the former leader of the International Monetary Fund, Dominique Strauss-Kahn, was accused of sexually assaulting a maid in a hotel room in New York. Strauss-Kahn was cleared of all charges on the 23rd of August 2011 since it could not be proven that he had forced the maid to have sexual relations with him. The purpose of this study is to examine how the case was framed in two Swedish newspapers, Svenska Dagbladet and Aftonbladet. Svenska Dagbladet is a broadsheet newspaper and Aftonbladet is a tabloid newspaper. The purpose of this study is also to find differences and similarities in the framing of the case in broadsheet newspapers and tabloid newspapers. The study is primarily based on two different theories; the framing theory and the tabloidization theory. The method used is critical discourse analysis based on van Dijks theories and methods. A total of ten articles were examined, five from Svenska Dagbladet and five from Aftonbladet. Our result revealed that both Svenska Dagbladet and Aftonbladet used dramaturgical methods like exaggeration and speculation in their reporting. The two newspapers also constructed the storyline about the persons involved in a similar way. These results indicate that the gap between how broadsheet newspapers and tabloid newspapers write their stories is decreasing.

Plusieurs structures en béton armé construites il y a maintenant près de 70 ans présentent aujourd'hui des défaillances et une capacité inadéquate ne répondant plus aux besoins dictés par un nouvel usage. La réhabilitation de ces structures présente un défi de taille pour l'ingénieur qui doit trouver des solutions économiques et techniquement viables pour rendre ces bâtiments sécuritaires. Le renforcement des structures en béton armé avec l'aide de matériaux composites avancés (MCA) offre une solution intéressante. Les MCA possèdent des caractéristiques avantageuses et sont d'application facile. Plusieurs structures à travers le monde ont été renforcées avec ce type de matériaux. Nous présentons dans ce mémoire les résultats expérimentaux et théoriques sur le renforcement à l'aide de MCA de poutres armées du système d'armature Kahn. Les poutres, au nombre de trois, proviennent de l'édifice Eaton situé sur la rue Ste-Catherine à Montréal. Des essais à quatre points pour la résistance en flexion et à trois points pour la résistance en cisaillement ont été préalablement effectués dans le but d'évaluer expérimentalement la capacité des poutres avant leur réhabilitation.

Les langages synchrones ont été fondés pour modéliser et implémenter les systèmes réactifs temps-réels critiques. Avec la complexité toujours croissante des systèmes contrôlés, la vitesse d'exécution devient un critère important. Nous sommes donc à la recherche d'une exécution parallèle, combinant efficacité et sûreté.Les langages synchrones ont toujours intégré la notion de parallélisme, mais ce, pour l'expressivité de la modélisation. Leurs compilations visent principalement les circuits ou la génération de code séquentiel. Tous ont une sémantique formelle, qui rend possible la distribution correcte du code. Mais la préservation de cette sémantique peut être un obstacle à l'efficacité du code généré, particulièrement s'il est nécessaire de préserver une notion d'instant global au système.Le modèle sémantique qui nous intéresse est celui des réseaux de Kahn. Ces réseaux modélisent des calculateurs distribués, communiquant au travers de files de taille non bornée. Dans ce cadre, la distribution ne demande aucune communication ni synchronisation supplémentaire. En considérant l'histoire des files de communication, la sémantique de Kahn permet de s'abstraire de l'exécution effective, tout en garantissant le déterminisme du calcul. Pour cela, chaque nœud du réseau doit avoir une sémantique fonctionnelle continue.Le langage que nous développons est Heptagon, un langage synchrone fonctionnel du premier ordre, déscendant de Lustre. Son compilateur est un prototype universitaire, apparenté à l'outil industriel Scade. Grâce à sa sémantique de Kahn, la distribution d'un programme Heptagon ne pose pas de question, son efficacité beaucoup plus.L'efficacité requiert de minimiser les synchronisations. Cela revêt deux aspects non indépendants. Avoir un découplage suffisant des calculs : il y a des délais dans les dépendances entre calculs. Avoir une granularité importante des calculs : un fort ratio temps de calcul sur fréquence de communication. Or la sémantique synchrone et les horloges d'un programme Heptagon reflètent exactement l'inverse. Elles permettent au programmeur de se contenter d'un découplage d'un instant et à chaque instant, au maximum une valeur est calculée. De plus, les instants sont typiquement courts, pour assurer que le système réagit rapidement.Des précédents travaux sur le sujet, nous tirons deux constats.Le premier est que nous souhaitons le contrôle du parallélisme par le programmeur, directement dans le code source. Il doit pouvoir maîtriser à quels instants il y a communication ou synchronisation. La solution que nous proposons dans ce manuscrit est l'utilisation des futures dans Heptagon. Ils fournissent ce pouvoir au programmeur, tout en restant des annotations qui peuvent être supprimées sans changer la sémantique dénotationnelle du programme.Le deuxième constat est que la question de la granularité des calculs est une question profonde, touchant en particulier aux questions de dépendance de données, de choix des horloges et de compilation modulaire. Heptagon, comme ses parents, restreint les réseaux de Kahn qui peuvent être écrits, de telle sorte que ces trois questions se traitent séparément. Pour mieux comprendre le lien entre ces éléments, nous revenons aux réseaux de Kahn. Notre principal résultat est la définition de la sous-classe des réseaux ordonnés réactifs. Ceux-ci sont les seuls pour lesquels nous pouvons décrire modulairement le comportement avec des horloges, sans restreindre les contextes d'appels. Ces réseaux ont une signature d'horloge en forme normale, qui maximise la granularité. Pour l'exprimer, nous introduisons les horloges entières, décrivant la communication de plusieurs valeurs en un seul instant. Nous appliquons ensuite nos résultats pour voir sous un nouveau jour Heptagon, Signal, les politiques des objets de Lucid Synchrone, mais aussi proposer une analyse pleinement modulaire de Lucy-n langage synchrone le plus fidèle aux réseaux de Kahn.

The emergency of complex phenomena in our time has forced creators to reconnect knowledge in design, since at the moment, most of them have fragmentary and hyper specialized inertia. Due to this, nowadays, in architecture the interest for hidden or little-known historic figures, related to science and technology, that for years looked for answers of design within the interconnection of different dimensions of reality, especially in conjunction with models of generative systems. This condition or problem on the daily chore allows us to approach to more general topics around the way man comes into contact with ideas and how it materializes them. In this case, the specific interest lies in how this happens in the architecture of the North American Northeast, or more exactly in the North American derivations of European theories, around the middle of the 20th century. That is, the moment in which there was a traffic of figures of science and technology between Europe and North America, which nurtured the architecture. Specifically, this text is interested in the figure of the architect A. G. Tyng, who maintained a strong professional and personal relationship with L. I. Kahn, one of the most notable figures of twentieth-century architecture. In this way, the initial concern was; how did she reconnect knowledge and how she materialized her seminal work between 1951 and 1953? Then, the objective of this thesis is to decipher the set of norms and rules that make up the practical theoretical world of A. G. Tyng, through the exegesis of his seminal work between 1951 and 1953, and his special relationship with L. I. Kahn. The answer to our research question was constructed from a qualitative descriptive-critical view, in which the inductive inferences, the abduction and methodologic empiricism prevailed. The physical description was privileged in this document, thanks to its presence in the present, what allowed it we face the theory and phenomena manifesto, as well as its comprehension and its internal laws’. Couple with the above, it is important to highlight that this thesis approached a different angle than usual, and at the same time, opened a space of historiographical experimentation where the hypotheses of these great stories were tested. The results of the study indicated how the ideal of progress, coupled with science and technology in the mid-20th century United States, fueled a traffic of ideas between the professional and educational worlds. This generated a readjustment in the reductive and totalizing architectural models, dominant at that time, a fact that guided A. G. Tyng in the process of articulating fragmented knowledge in disciplines or fields of knowledge towards interdisciplinary and transdisciplinary reflexive models close to generative systems. Namely, it helped her in her search for tomorrow's structures. In conclusion, this process contributed to the construction of a new critical path for architecture and provided evidence to rearrange the history of L. I. Kahn, one of the great figures of architecture. He also delegated to us the bases of the visionary theories of A. G. Tyng, which represents an invaluable collection for research interested in the affinity to numbers and their similarity with computer-aided design logics or their similarity with design, close to the scientific paradigm or complex thought.
La emergencia de los fenómenos complejos en nuestro tiempo ha obligado a los creadores a reconectar conocimientos en el diseño, ya que, actualmente, muchos presentan una inercia fragmentaria e hiperespecializada. En razón a esto, en la arquitectura se ha despertado hoy día el interés por las figuras históricas ocultas o poco conocidas, próximas a la ciencia y a la tecnología, que por años buscaron respuestas de diseño en la interconexión de distintas dimensiones de lo real, especialmente en conexión con modelos de sistemas generativos. Esta condición o problemática en el quehacer investigativo nos permite aproximarnos a temas más generales en torno a la forma en que el hombre entra en contacto con las ideas y cómo las materializa. En este caso, el interés específico radica en cómo sucede esto en la arquitectura del noreste norteamericano, más exactamente en las derivaciones norteamericanas de las teorías europeas, alrededor de la mitad del siglo XX; esto es, el momento en el cual sobrevino un tráfico de figuras de la ciencia y la tecnología entre Europa y Norteamérica, que nutrió la arquitectura. De manera puntual, este documento se interesa en la figura de la arquitecta Tyng quien mantuvo una fuerte relación profesional y personal con Kahn, una de las figuras más notables de la arquitectura del siglo XX. De esta manera, la inquietud inicial fue: ¿Cómo reconectó ella conocimientos y cómo materializó su obra seminal entre 1951 y 1953? Luego, el objetivo de esta tesis es descifrar el conjunto de normas y reglas que conforman el mundo teórico práctico de Tyng ¿a través de la exégesis de su obra seminal entre 1951 y 1953¿ y su especial relación con Kahn. La respuesta a esta pregunta de investigación fue construida a partir de una visión cualitativa descriptiva-critica, en la que primaron las inferencias inductivas, la abducción y el empirismo metodológico. La descripción física fue privilegiada en este documento, gracias a su existencia en el presente, lo que permitió enfrentar la teoría y el fenómeno manifiesto, así como su comprensión y la de sus leyes internas. Aunado a lo anterior, es importante resaltar que esta tesis abordó un enfoque distinto al habitual y a la vez abrió un espacio de experimentación historiográfica en el que las hipótesis de esas grandes historias fueron puestas a prueba. Los resultados del estudio indicaron cómo el ideal de progreso, unido a la ciencia y a la tecnología en los Estados Unidos de mediados del siglo XX, alimentaron un tráfico de ideas entre el mundo profesional y educativo. Este generó un reajuste en los modelos arquitectónicos reductivos y totalizantes, dominantes en ese tiempo, hecho que dirigió a Tyng en el proceso de articular los conocimientos fragmentados en disciplinas o campos de saber hacia modelos reflexivos interdisciplinarios y transdisciplinarios cercanos a los sistemas generativos. A saber, la ayudó en su búsqueda de las estructuras del mañana. En conclusión, este proceso contribuyó en la construcción de un camino crítico nuevo para la arquitectura y aportó pruebas para reacomodar la historia de Kahn, una de las grandes figuras de la arquitectura. Así mismo, nos mostró las bases de las visionarias teorías de Tyng, lo que representa un acervo invaluable para las investigaciones interesadas por la afinidad al número y por su similitud con las lógicas de diseño asistido por ordenador o por su semejanza con el diseño, cercano al paradigma científico o al pensamiento complejo.

This study was designed to ascertain, analyse and compare the perceptions of College Librarians and their associates about the role responsibility which College Librarians in libraries in New South Wales Colleges of Advanced Education (CAEs) were actually assuming and ideally should be assuming as part of their role as library managers. Using as its basis a theoretical framework of role and role-related concepts, as developed by social psychologists such as Kahn et al. (1964), a role set group of Principals, Registrars and Senior Library Staff was identified as the survey population. A review of the literature about CAEs and their libraries and overseas studies about the role of library managers assisted with the development of a role responsibility questionnaire. Data from the questionnaire was analysed in respect of actual and ideal role responsibility and any gaps between actual and ideal role responsibility. Gaps between perceptions of actual and ideal role responsibility between College Librarians and associates may indicate a potential for role conflict for persons enacting the role of College Librarian. This study found statistically significant results in respect of both actual and ideal role responsibility between College Librarians and Senior Library Staff, which indicated that there was not clear agreement between the two groups about either the role responsibility currently assumed by College Librarians and that which ideally should be assumed. In respect of the gap between actual and ideal role responsibility, however, there was no statistically significant result between College Librarians and associates, indicating that the potential for role conflict resulting from divergent perceptions between role set groups was not evident. This does not preclude the potential for role conflict from other sources.

La variabilidad morfológica de los caracteres vegetativos y la estructura de las poblaciones de Astrocaryum perangustatum (ARECACEAE) fue evaluada en una población de esta especie, que ocupa las zonas deforestadas (pastizales) y no deforestadas (zonas de bosque) de Pozuzo (Pasco, Perú). Para estudiar la variabilidad morfológica de las plántulas y los adultos, fueron medidos 105 plántulas (56 en pastizales y 49 en zonas de bosque, en las cuales se evaluó el número de hojas por plántula y largo del limbo y peciolo) y 60 adultos (30 en pastizales y 30 en zonas de bosque a las cuales se les midió el tamaño del tallo, número de frondas y largo de la fronda, pecíolo, raquis, ancho y largo de los foliolos y el tamaño de las aguijones) que se encontraron en las parcelas. A fin de conocer la estructura de las poblaciones, fueron establecidos un total de 50 parcelas de 400m2 cada una (25 en pastizales y 25 en zonas boscosas), haciendo un total de 2 hectáreas de evaluación. En cada parcela se registraron la densidad de plántulas, juveniles (I y II) y adultos. En cuanto a los caracteres morfológicos, se aprecia la gran variabilidad de los caracteres morfológicos vegetativos estudiados en los adultos y plántulas de la población de Pozuzo. La comparación de los parámetros morfológicos obtenidos con las muestras de herbario, nos revela la gran plasticidad morfológica que tiene esta especie en el área de estudio. Las palmeras adultas de las zonas boscosas presentan un mayor promedio en el largo del raquis (607,54 cm), pecíolo y vaina (106,03 cm), largo de las pinnas proximales (109,85 cm) y largo del aguijón mayor (25,84 cm) que aquellas palmeras de los pastizales (con 444,80 cm; 85,70 cm; 85,03 cm y 17,66 cm para el largo del raquis, largo del peciolo y vaina, largo de las pinnas proximales y largo del aguijón mayor en promedio respectivamente). En los pastizales las palmeras adultas tienen en promedio tallo más alto (4,19 m), pinnas medias más anchas (8,66 cm), mayor largo x ancho de las pinas medias (933,63 cm2) y mayor número de frondas (9,96) en comparación con los adultos de los ambientes boscosos (2,59 m; 6,08 cm; 652,28 cm2 y 6,63 para la altura del tallo, ancho de las pinnas medias, largo x ancho de las pinnas medias y número de frondas respectivamente). Las plántulas de las zonas de boscosas tuvieron un mayor largo del limbo (27,08 cm en promedio), peciolo (22,39cm), y un mayor número de hojas (2,95) que las plántulas en los pastizales (17,35cm; 10,12cm y 2,05 para el tamaño de limbo, peciolo y número de hojas promedio respectivamente). Se discute la importancia de la intensidad de luz como uno de los parámetros que afectan la morfología de esta especie. La estructura de la población de Astrocaryum perangustatum en Pozuzo fue diferente en los bosques y los pastizales. La proporción de adultos fue mayor en las zonas boscosas (29%) en comparación con los pastizales (22%). En promedio hubo una mayor cantidad de adultos en floración en los pastizales (1 por parcela) que en zonas boscosas (0.44 por parcela). Los juveniles fueron ausentes en los pastizales, mientras que en las zonas boscosas representaron el 17%. No se encontraron diferencias significativas a nivel del estadío de plántulas, cuya proporción fue similar en los pastizales (78%) y zonas boscosas (53%). Se discute el posible efecto de las actividades ganaderas y agrícolas sobre las poblaciones de esta especie.

Magnesium alloys are a popular research topic for structural applications because they have a lower density than conventional structural materials, including steel, titanium, and aluminum; however, the reliability and safety of their mechanical properties must be further proven. An important mechanical property for this purpose is fracture toughness, which is the measure of the material's resistance to crack propagation. In this study, a model of an experiment to investigate the fracture toughness of a magnesium alloy WE43 before and after friction stir processing (FSP) is developed, and the results are compared to those produced by a digital image correlation (DIC) system during an experiment from another paper. The model results of the material before FSP matched well with the DIC results, but the model of the material after FSP only partially matches the DIC results. In addition, a theoretical approach to calculating the standard fracture toughness value, KIc, from the modeling results is proposed, and is found to be a conservative approach.
