Red meat intake-induced increases in fecal water genotoxicity correlate with pro-carcinogenic gene expression changes in the human colon

Red meat consumption is associated with an increased colorectal cancer (CRC) risk, which may be due to an increased endogenous formation of genotoxic N-nitroso compounds (NOCs). To assess the impact of red meat consumption on potential risk factors of CRC, we investigated the effect of a 7-day dietary red meat intervention in human subjects on endogenous NOC formation and fecal water genotoxicity in relation to genome-wide transcriptomic changes induced in colonic tissue. The intervention showed no effect on fecal NOC excretion but fecal water genotoxicity significantly increased in response to red meat intake. Colonic inflammation caused by inflammatory bowel disease, which has been suggested to stimulate endogenous nitrosation, did not influence fecal NOC excretion or fecal water genotoxicity. Transcriptomic analyses revealed that genes significantly correlating with the increase in fecal water genotoxicity were involved in biological pathways indicative of genotoxic effects, including modifications in DNA damage repair, cell cycle, and apoptosis pathways. Moreover, WNT signaling and nucleosome remodeling pathways were modulated which are implicated in human CRC development. We conclude that the gene expression changes identified in this study corroborate the genotoxic potential of diets high in red meat and point towards a potentially increased CRC risk in humans.

Issues in language and development in multilingual settings: a case-study of knowledge exchange and teacher education in South Africa

The quality of a country’s human-resource base can be said to determine its level of success in social and economic development. This study focuses on some␣of the major human-resource development issues that surround the implementation of South Africa’s policy of multilingualism in education. It begins by discussing the relationship between knowledge, language, and human-resource, social and economic development within the global cultural economy. It then considers the situation in South Africa and, in particular, the implications of that country’s colonial and neo-colonial past for attempts to implement the new policy. Drawing on the linguistic-diversity-in-education debate in the United Kingdom of the past three decades, it assesses the first phase of an in-service teacher-education programme that was carried out at the Project for Alternative Education in South Africa (PRAESA) based at the University of Cape Town. The authors identify key short- and long-term issues related to knowledge exchange in education in multilingual societies, especially concerning the use of African languages as mediums for teaching and learning.

Sustentabilidade e Desenvolvimento Local: Estudo de Projeto na Formação da Ecovila Viver Simples em Itamonte - MG

Eco-villages are considered models of intentional communities or sustainable communities and have been incorporated by the United Nations in the Sustainable Communities Development Programme (SCDP) as a human scale settlement. They are characterized by human activities being integrated in a non-damaging way into the natural world in such a way as to give support to healthy human development so as to be able to continue indefinitely into the future. This text assesses the extent to which a project to create the Eco-village for Simple Living in Itamonte - Minas Gerais" is successful, based on the concepts of sustainability and local development succeeds, by examining the indicators and attributes that are able to be measured in the planning phase, describing the stages and discussions of the project, as well as assessing the members 'perception of "the concepts of the Eco-village", "sustainability" and "local development". Subsequent analysis of the degree of sustainability (ecological, social, economic, spacial and cultural / spiritual) and local development, based on the social economy, demonstrated the presence of a number of aspects used to support, guide, discuss, plan and implement actions in the creation of the Eco-village being studied. This work could be used as a guide to Eco-villages during the planning phase, indicating the importance of the concepts studied, especially for some communities which are self-proclaimed "Eco-villages" but which in fact do not show even the slightest structural aspects which would describe them as such, like solidarity in the relations between participants, or construction oriented with a view to the precepts of environmental preservation.

Structural aspects of postnatal lung development - alveolar formation and growth

The human lung is born with a fraction of the adult complement of alveoli. The postnatal stages of human lung development comprise an alveolar stage, a stage of microvascular maturation, and very likely a stage of late alveolarization. The characteristic structural features of the alveolar stage are well known; they are very alike in human and rat lungs. The bases for alveolar formation are represented by immature inter-airspace walls with two capillary layers with a central sheet of connective tissue. Interalveolar septa are formed by folding up of one of the two capillary layers. In the alveolar stage, alveolar formation occurs rapidly and is typically very conspicuous in both species; it has therefore been termed 'bulk alveolarization'. During and after alveolarization the septa with double capillary networks are restructured to the mature form with a single network. This happens in the stage of microvascular maturation. After these steps the lung proceeds to a phase of growth during which capillary growth by intussusception plays an important role in supporting gas exchange. In view of reports that alveoli are added after the stage of microvascular maturation, the question arises whether the present concept of alveolar formation needs revision. On the basis of morphological and experimental findings we can state that mature lungs contain all the features needed for 'late alveolarization' by the classical septation process. Because of the high plasticity of the lung tissues, late alveolarization or some forms of compensatory alveolar formation may be considered for the human lung.

Adrenal gland development and defects

The network regulating human adrenal development is complex. Studies of patients with adrenal insufficiency due to gene mutations established a central role for transcription factors GLI3, SF1 and DAX1 in the initial steps of adrenal formation. Adrenal differentiation seems to depend on adrenocorticotropic hormone (ACTH) stimulation and signalling, including biosynthesis and action of POMC, PC1, TPIT, MC2R, MRAP and ALADIN, all of which cause adrenocortical hypoplasia when mutated in humans. Studies of knockout mice revealed many more factors involved in adrenal development; however, in contrast to rodents, in humans several of those factors had no adrenal phenotype when mutated (e.g. WT1, WNT4) or, alternatively, human mutations have not (yet) been identified. Tissue profiling of fetal and adult adrenals suggested 69 genes involved in adrenal development. Among them were genes coding for steroidogenic enzymes, transcription and growth factors, signalling molecules, regulators of cell cycle and angiogenesis, and extracellular matrix proteins; however, the exact role of most of them remains to be elucidated.

Brand Authenticity: An Integrative Framework and Measurement Scale

This article develops an integrative framework of the concept of perceived brand authenticity (PBA) and sheds light on PBA’s (1) measurement, (2) drivers, (3) consequences, as well as (4) an underlying process of its effects and (5) boundary conditions. A multi-phase scale development process resulted in a 15-item PBA scale to measure its four dimensions of credibility, integrity, symbolism, and continuity. PBA is influenced by indexical, existential, and iconic cues, whereby the latter’s influence is moderated by consumers’ level of marketing skepticism. Results also suggest that PBA drives brand choice likelihood through self-congruence for consumers high in self-authenticity.

Brand Authenticity: An Integrative Framework and Measurement Scale

Although brand authenticity is gaining increasing interest in consumer behavior research and managerial practice, literature on its measurement and contribution to branding theory is still limited. This article develops an integrative framework of the concept of brand authenticity and reports the development and validation of a scale measuring consumers' perceived brand authenticity (PBA). A multi-phase scale development process resulted in a 15-item PBA scale measuring four dimensions: credibility, integrity, symbolism, and continuity. This scale is reliable across different brands and cultural contexts. We find that brand authenticity perceptions are influenced by indexical, existential, and iconic cues, whereby some of the latters' influence is moderated by consumers' level of marketing skepticism. Results also suggest that PBA increases emotional brand attachment and word-of-mouth, and that it drives brand choice likelihood through self-congruence for consumers high in self-authenticity.

Convergent etiology of Eker rat and human uterine leiomyoma

The Eker rat model has allowed researchers the unique opportunity to study the tumorigenesis of spontaneously occurring uterine leiomyoma. Animals in this line harbor a germline mutation in the tuberous sclerosis complex-2 (Tsc-2) tumor suppressor gene and develop uterine leiomyomas at a rate of ∼65%. Primary leiomyomas obtained from humans and Eker rats along with Eker-derived leiomyoma cell lines were used in studies described herein to determine the effect of PPARγ ligand treatment on the proliferation of this cell type and to determine the role of tuberin and p27Kip1 in the etiology of this tumor type. Treatment of leiomyoma cells of human and rat origin with PPARγ-activating compounds resulted in decreased proliferation. Additionally, PPARγ ligands inhibited estrogen-dependent gene transactivation in Eker-derived leiomyoma cells suggesting that nuclear receptor cross-talk may exist between PPAR and the ER and may be responsible for the inhibition of proliferation in this cell type. Loss of tuberin, the product of the TSC-2 gene, is associated with Eker rat leiomyoma development while the role of this tumor suppressor in human leiomyoma development is unknown. Data herein show that tuberin expression is diminished in 25% of human leiomyomas tested. Additionally, we observed diminished p27 Kip1 expression in 80% of human uterine leiomyomas compared to normal myometrium. Interestingly, the loss of tuberin expression in human leiomyoma was associated with cytoplasmic p27Kip1 accumulation in this cell type. Furthermore, tuberin-null Eker rat leiomyomas and derived cell lines had predominantly cytoplasmic p27Kip1 compared to tuberin-expressing normal myometrium. Taken together, our data show that human and Eker rat leiomyoma proliferation is inhibited upon PPARγ treatment and that the etiology of human and Eker rat leiomyoma converge at loss of p27Kip1 function. Furthermore, our data indicate that the loss of p27 Kip1 function is mediated by loss of expression (in 80% of human leiomyoma) or cytoplasmic localization potentially resulting from the loss of tuberin. ^

Capacity building in development projects

Development projects of different types mainly aim to alleviate poverty and ameliorate the livelihoods of local people. One of the strategies commonly used is to focus on organizations and build from their existing capacities in order to improve their living standards or try to build new organizations to work in a common project. Social and human capitals are two key components of these organizations and they might be crucial to the success of the actions that they accomplish. Both can be considered as part of the social capacity of the local organization. This capacity can be enforced with development projects through capacity building. This term means much more than training activities as it includes not only human resource development but also organizational and institutional development (UNESCO, 2010). Capacity and capacity building concepts, as well as capacity measurements in this context are explored to build a framework to evaluate the social capacity generated with the interventions and better plan the actions to be undertaken by the projects to succeed. The focus is set on rural development projects.

Emergencia y convergencia de las corrientes urbanísticas alternativas al desarrollo disperso. Europa y los EE.UU. 1980/2010

La presente tesis doctoral identifica el reciente fenómeno de la emergenciai de corrientes urbanísticas que actúan en la periferia urbana a partir de una concepción del diseño urbano que propugna modelos más compactos, a escala humana, de carácter integral y sostenible, como alternativa al desarrollo disperso y difusoii que caracteriza en gran medida a la ciudad contemporánea. Se develan las diferencias de origen y las coincidencias entre las distintas líneas de pensamiento que definen a estas emergentes corrientes alternativas, situándolas dentro de determinados enfoques planteados en la presente tesis, y demostrando con ello, las progresivas áreas de convergencia que permiten su ordenamiento como fenómeno histórico común. Estas distintas líneas de pensamiento, que derivan en las corrientes urbanísticas alternativas, se manifiestan primeramente como reacción a las operaciones modernistas de la posguerra, pero crecientemente expresan una visión contestataria a la expansión urbana descontrolada iii, de bajas densidades, zonificación excluyente y dependiente del automóvil; modelo asociado a las autopistas urbanas, los llamados nuevos artefactos urbanos y las grandes parcelas destinadas a proyectos habitacionales. Una realidad expresada en variados contextos en el ámbito de la globalización económica y cultural que, en gran medida, se singulariza como responsable de las profundas transformaciones urbanas, de la consecuente gradual pérdida de habitabilidad en las ciudades y del impacto sobre el medio natural; cuestión a tratar en el “Marco conceptual” referido al contexto y problema de la tesis. Se estudian los planteamientos fundamentales que postulan estas corrientes alternativas en el contexto de la expansión urbana horizontal, con el fin de identificar las distintas vertientes o líneas existentes, de establecer sus orígenes, enfoques, vínculos y alcances, permitiendo con ello caracterizar el fenómeno en sí desde una visión original e integradora. Estas corrientes a tratar han surgido en diversos momentos y con diversas particularidades, pero con mayor intensidad, articulación y visibilidad a partir de los años ochenta y especialmente en los noventa del siglo recién pasado, fundamentalmente en Europa y en los Estados Unidos de América, representando el “Cuerpo teórico” de esta tesis. Emergen en un escenario de creciente empoderamiento ciudadano, en tiempos de una mayor conciencia ambiental y social, y desde la convicción extendida de las limitaciones de un desarrollismo que, en términos del territorio físico, se manifiesta en el crecimiento urbano por extensión, incremental y desarticulado; tienen distintos idearios de origen, algunos en aparente contradicción o manifiesta oposición entre sí; se articulan desde diversos énfasis y surgen a partir de distintas aproximaciones. Para poder comprender el fenómeno de manera integral, se identifican y observan las tendencias contemporáneas y las correspondientes corrientes principales del diseño urbano; se indaga en sus discursos críticos y se ordenan en función de tres enfoques, los cuales reúnen los fundamentos esenciales de las distintas miradas críticas al modelo disperso y difuso: el enfoque neotradicional, el enfoque de la movilidad, y el enfoque ecológicoiv. Reconociendo la importancia de las operaciones de renovación urbana en la “ciudad intramuros” y siendo partícipes de estas intervenciones, las diferentes corrientes observadas desde los tres enfoques planteados, tienen un común denominador disciplinar en cuanto a su preocupación por generar actuaciones urbanas viables y practicables que causen un menor impacto sobre el territorio y que ofrezcan las condiciones para mejorar la habitabilidad en la ciudad, asumiendo el crecimiento hacia las periferias desde una aproximación alternativa a los modelos hoy predominantes. Las distintas corrientes, desde los particulares enfoques señalados, pretenden en síntesis, un desarrollo que refuerce el rol del diseño urbano, que promueva modelos más compactosv, de usos mixtos compatibles con la residencia y con espacios públicos de calidad, a una escala apropiada para la movilidad peatonal, favoreciendo de esta manera el uso del transporte público y velando consecuentemente por aquellos aspectos que mejoren las condiciones de sostenibilidad. En definitiva, el ideario de las corrientes caracterizadas en esta tesis como alternativas, se origina y se sostiene a partir de la convicción de situar a la disciplina del diseño urbano en su justa medida en el desarrollo contemporáneo, en el convencimiento de la relevancia del proyecto urbano en el ordenamiento del territorio y el crecimiento de las ciudades actuales. Una convergencia implícita a tratarse en la “Discusión de resultados”. La preocupación que reflejan las distintas corrientes estudiadas por el hábitat construido, en cuanto a su condición de acoger y estimular la dimensión humana de las ciudades, puede resumirse en una cita del arquitecto danés Jan Gehl, que interpreta a muchas de las líneas de pensamiento que se abordan en esta tesis, en cuanto al deseo de crear mejores ciudades: “Aspiramos generar ciudades animadas, saludables, atractivas, sostenibles y seguras, con el propósito de mejorar la calidad de vida de la gente”. ABSTRACT This Ph.D thesis identifies the recent phenomenon of the emergence of alternative urban design currents in the city edge, that focus on a more compact, human-scale oriented, comprehensive and sustainable urban design as an alternative to the overwhelming advance of sprawl that largely characterizes the contemporary city. It singles out the differences in origin, as well as the similarities drawn from the different lines of thought that define these emergent alternative currents, placing them within certain approaches proposed in this thesis, and thereby demonstrating the progressive areas of convergence that allow to arrange them as a common historical phenomenon. Indeed, the different lines of thought that drift towards these alternative urbanistic currents, first appear as a reaction to the post- World War II Modernist housing projects, and increasingly more so as a response to urban sprawl; an ever expanding phenomemnon expressed in different contexts within the economic and cultural globalization, largely singled out as being responsible for the deep urban transformations, the consequent gradual loss of livability and the impact on natural environment, setting the “Conceptual framework” of this thesis. Within the context of urban sprawl, the fundamental principles of these alternative currents are studied to establish their origins, approaches, linkages and scope, in order to zero in on the various aspects or existing lines and thereby allowing the identification of the phenomenon from an original and inclusive vision. The alternative currents to be dealt with, emerged at different times and with diverse characteristics, nonetheless it is in the eighties and especially during the nineties, mainly in Europe and the United States, where they appear with greater intensity, coordination and visibility, representing the “Theoretical body” of this thesis. The above mentioned currents arise in a scenario of increasing citizen empowerment in times of growing environmental and social awareness, along with the widespread conviction of the limitations of a quantitative development expressed as a physical manifestation in urban sprawl. These alternative currents have a different philosophy in origin, some are in apparent contradiction or in definite opposition, being organized from different approaches and emphases. To comprehend this phenomenon, it is necessary to identify and analize the contemporary trends and the main currents of urban design, inquiring and arranging their critical discourses according to three approaches that meet the essential foundations of the various critical perspectives of urban sprawl: the neo-traditional approach, the mobility approach, the ecological approach. Acknowledging the importance of urban renovation in the “Inner City”, and being partakers of these interventions, the different currents identified from these three approaches, concur in their concern for the development of viable and workable alternatives to urban sprawl; models that cause a lower impact on the territory, whilst improving livability in the city. The different currents recognized within the above mentioned approaches, advocate in brief, for a development that strengthens the role of urban design, that encourages more compact models, mixed-uses, and quality public spaces, considering the human scale and walkability; thereby increasing public transport and promoting consequently, the conditions for sustainable development. Ultimately, the philosophy of the so called alternative currents, is based on the belief of placing urban design as a fundamental discipline in contemporary urban development. The concern for the built habitat reflected by the various currents studied, as of their condition to accept and stimulate the human dimension of the city, can be summed up in a quote from Danish architect Jan Gehl, who represents many of the lines of thought addressed, in the belief of creating better cities: “We aspire to create cities that are lively, healthy, attractive, sustainable and safe-and thereby improve people’s quality of life”.

1950 En torno al Museo Louisiana 1970

La tesis “1950 En torno al Museo Louisiana 1970” analiza varias obras relacionadas con el espacio doméstico, que se realizaron entre 1950 y 1970 en Dinamarca, un periodo de esplendor de la Arquitectura Moderna. Tras el aislamiento y restricciones del conflicto bélico que asoló Europa, los jóvenes arquitectos daneses, estaban deseosos por experimentar nuevas ideas de procedencia internacional, favorecidos por diferentes circunstancias, encuentran el mejor campo de ensayo en el espacio doméstico. La mejor arquitectura doméstica en Dinamarca, de aquel periodo, debe entenderse como un sistema compuesto por diferentes autores, que tienen en común muchas más similitudes que diferencias, se complementan unos a otros. Para la comprensión y el entendimiento de ello se hace necesario el estudio de varias figuras y edificios, que completen este sistema cuya investigación está escasamente desarrollada. La tesis propone un viaje para conocer los nombres de algunos de sus protagonistas, que mostraron con su trabajo, que tradición y vanguardia no estarán reñidas. El objetivo es desvelar las claves de la Modernidad Danesa, reconocer, descubrir y recuperar el legado de algunos de sus protagonistas en el ámbito doméstico, cuya lección se considera de total actualidad. Una arquitectura que asume las aportaciones extranjeras con moderación y crítica, cuya íntima relación con la tradición arquitectónica y la artesanía propias, será una de sus notas especiales. Del estudio contrastado de varios proyectos y versiones, se obtienen valores comunes entre sus autores, al igual que se descubren sus afinidades o diferencias respecto a los mismos asuntos; que permitirán comprender sus actuaciones según las referencias e influencias, y definir las variables que configuran sus espacios arquitectónicos. La línea de conexión entre los edificios elegidos será su particular relación con la naturaleza y el lugar en que se integran. La fachada, lugar donde se negociará la relación entre el interior y el paisaje, será un elemento entendido de un modo diferente en cada uno de ellos, una relación que se extenderá en todas ellas, más allá de su perímetro. La investigación se ha estructurado en seis capítulos, que van precedidos de una Introducción. En el capítulo primero, se estudian y se señalan los antecedentes, las figuras y edificios más relevantes de la Tradición Danesa, para la comprensión y el esclarecimiento de algunas de las claves de su Modernidad en el campo de la Arquitectura, que se produce con una clara intención de encontrar su propia identidad y expresión. Esta Modernidad floreciente se caracteriza por la asimilación de otras culturas extranjeras desde la moderación, con un punto de vista crítico, y encuentra sus raíces ancladas a la tradición arquitectónica y la artesanía propia, que fragua en la aparición de un ideal común con enorme personalidad y que hoy se valora como una auténtica aportación de una cultura considerada entonces periférica. Se mostrará el debate y el camino seguido por las generaciones anteriores, a las obras análizadas. Las sensibilidades por lo vernáculo y lo clásico, que aparentemente son contradictorias, dominaran el debate con la misma veracidad y respetabilidad. La llamada tercera generación por Sigfried Giedion reanudará la práctica entre lo clásico y lo vernáculo, apoyados en el espíritu del trabajo artesanal y de la tradición, con el objetivo de conocer del acto arquitectónico su “la verdad” y “la esencia original”. El capítulo segundo, analiza la casa Varming, de 1953, situada en un área residencial de Gentofte, por Eva y Nils Koppel, que reinterpreta la visión de Asplund de un paisaje interior continuación del exterior, donde rompen la caja de ladrillo macizo convencional propia de los años 30. Es el ejemplo más poderoso de la unión de tradición e innovación en su obra residencial. Sus formas sobrias entre el Funcionalismo Danés y la Modernidad se singularizarán por su abstracción y volúmenes limpios que acentúan el efecto de su geometría, prismática y brutalista. El desplazamiento de los cuerpos que lo componen, unos sobre otros, generan un ritmo, que se producirá a otras escalas, ello unido a las variaciones de sus formas y a la elección de sus materiales, ladrillo y madera, le confieren a la casa un carácter orgánico. El edificio se ancla a la tierra resolviéndose en diferentes niveles tras el estudio del lugar y su topografía. El resultado es una versión construida del paisaje, en la cual el edificio da forma al lugar y ensalza la experiencia del escenario natural. La unidad de las estructuras primitivas, parece estar presente. Constituye un ejemplo de la “La idea de Promenade de Asplund”, el proyecto ofrece diferentes recorridos, permitiendo su propia vivencia de la casa, que ofrece la posibilidad vital de decidir. El capítulo tercero trata sobre el pabellón de invitados de Niels Bohr de 1957, situado un área boscosa, en Tisvilde Hegn, fue el primer edificio del arquitecto danés Vilhelm Wohlert. Arraigado a la Tradición Danesa, representa una renovación basada en la absorción de influencias extranjeras: la Arquitectura Americana y la Tradición Japonesa. La caja de madera, posada sobre un terreno horizontal, tiene el carácter sensible de un organismo vivo, siempre cambiante según las variaciones de luz del día o temperatura. Cuando se abre, crea una prolongación del espacio interior, que se extiende a la naturaleza circundante, y se expande hacia el espacio exterior, permitiendo su movilización. Se establece una arquitectura de flujos. Hay un interés por la materia, su textura y el efecto emocional que emana. Las proporciones y dimensiones del edificio están reguladas por un módulo, que se ajusta a la medida del hombre, destacando la gran unidad del edificio. La llave se su efecto estético está en su armonía y equilibrio, que transmiten serenidad y belleza. El encuentro con la naturaleza es la lección más básica del proyecto, donde un mundo de relaciones es amable al ser humano. El capítulo cuarto, analiza el proyecto del Museo Louisiana de 1958, en Humlebæk, primer proyecto de la pareja de arquitectos daneses Jørgen Bo y Vilhelm Wohlert. La experiencia en California de Wohlert donde será visitado por Bo, será trascendental para el desarrollo de Louisiana, donde la identidad Danesa se fusiona con la asimilación de otras culturas, la arquitectura de Frank Lloyd Wright, la del área de la Bahía y la Tradición Japonesa principalmente. La idea del proyecto es la de una obra de arte integral: arquitectura, arte y paisaje, coexistirían en un mismo lugar. Diferentes recursos realzarán su carácter residencial, como el uso de los materiales propios de un entorno doméstico, la realización a la escala del hombre, el modo de usar la iluminación. Cubiertas planas que muestran su artificialidad, parecen flotar sobre galerías acristaladas, acentuarán la fuerza del plano horizontal y establecerán un recorrido en zig-zag de marcado ritmo acompasado. Ritmo que tiene que ver con la encarnación del pulso de la naturaleza, que se acompaña de juegos de luz, y de otras vibraciones materiales a diferentes escalas, imagen, que encuentra una analogía semejante en la cultura japonesa. Todo se coordina con la trama estructural, que conlleva a una construcción y proporción disciplinada. Louisiana atiende al principio de crecimiento de la naturaleza, con la que su conexión es profunda. Hay un dinamismo expresado por el despliegue del edificio, que evoca a algunos proyectos de la Tradición Japonesa. Los blancos muros tienen su propia identidad como formas en sí mismas, avanzan prolongándose fuera de la línea del vidrio, se mueven libremente siguiendo el orden estructural, acompañando al espacio que fluye, en contacto directo con la naturaleza que está en un continuo estado de flujos. Se da todo un mundo de relaciones, donde existe un dialogo entre el paisaje, arte y arquitectura. El capítulo quinto, se dedica a analizar la segunda casa del arquitecto danés Halldor Gunnløgsson, de 1959. Evoca a la Arquitectura Japonesa y Americana, pero es principalmente resultado de una fuerte voluntad y disciplina artística personal. La cubierta, plana, suspendida sobre una gran plataforma pavimentada, que continúa la sección del terreno construyendo de lugar, tiene una gran presencia y arroja una profunda sombra bajo ella. En el interior un espacio único, que se puede dividir eventualmente, discurre en torno a un cuerpo central. El espacio libre fluye, extendiéndose a través de la transparencia de sus ventanales a dos espacios contrapuestos: un patio ajardinado íntimo, que inspira calma y sosiego; y la naturaleza salvaje del mar que proyecta el color del cielo, ambos en constante estado de cambio. El proyecto se elabora de un modo rigurosamente formal, existiendo al mismo tiempo un perfecto equilibrio entre la abstracción de su estructura y su programa. La estructura de madera cuyo orden se extiende más allá de los límites de su perímetro, está formada por pórticos completos como elementos libres, queda expuesta, guardando una estrecha relación con el concepto de modernidad de Mies, equivalente a la arquitectura clásica. La preocupación por el efecto estético es máxima, nada es improvisado. Pero además la combinación de materiales y el juego de las texturas hay una cualidad táctil, cierto erotismo, que flota alrededor de ella. La precisión constructiva y su refinamiento se acercan a Mies. La experiencia del espacio arquitectónico es una vivencia global. La influencia de la arquitectura japonesa, es más conceptual que formal, revelada en un respeto por la naturaleza, la búsqueda del refinamiento a través de la moderación, la eliminación de los objetos innecesarios que distraen de la experiencia del lugar y la preocupación por la luz y la sombra, donde se establece cierto paralelismo con el oscuro mundo del invierno nórdico. Hay un entendimiento de que el espacio, en lugar de ser un objeto inmaterial definido por superficies materiales se entiende como interacciones dinámicas. El capítulo sexto. Propone un viaje para conocer algunas de las viviendas unifamiliares más interesantes que se construyeron en el periodo, que forman parte del sistema investigado. Del estudio comparado y orientado en varios temas, se obtienen diversa conclusiones propias del sistema estudiado. La maestría de la sustancia y la forma será una característica distintiva en Dinamarca, se demuestra que hay un acercamiento a la cultura de Oriente, conceptual y formal, y unos intereses comunes con cierta arquitectura Americana. Su lección nos sensibiliza hacia un sentido fortalecido de proporción, escala, materialidad, textura y peso, densidad del espacio, se valora lo táctil y lo visual, hay una sensibilidad hacia la naturaleza, hacia lo humano, hacia el paisaje, la integridad de la obra. ABSTRACT The thesis “1950 around the Louisiana Museum 1970” analyses several works related to domestic space, which were carried out between 1950 and 1970 in Denmark, a golden age of modern architecture. After the isolation and limitations brought about by the war that blighted Europe, young Danish architects were keen to experiment with ideas of an international origin, encouraged by different circumstances. They find the best field of rehearsal to be the domestic space. The best architecture of that period in Denmark should be understood as a system composed of different authors, who have in common with each other many more similarities than differences, thus complimenting each other. In the interests of understanding, the study of a range of figures and buildings is necessary so that this system, the research of which is still in its infancy, can be completed. The thesis proposes a journey of discovery through the names of some of those protagonists who were showcased through their work so that tradition and avant- garde could go hand in hand. The objective is to unveil the keys to Danish Modernity; to recognise, discover and revive the legacy of some of its protagonists in the domestic field whose lessons are seen as entirely of the present. For an architect, the taking on of modern contributions with both moderation and caution, with its intimate relationship with architectural tradition and its own craft, will be one of his hallmarks. With the study set against several projects and versions, one can derive common values among their authors. In the same way their affinities and differences in respect of the same issue emerge. This will allow an understanding of their measures in line with references and influences and enable the defining of the variables of their architectural spaces. The common line between the buildings selected will be their particular relationship with nature and the space with which they integrate. The façade, the place where the relationship between the interior and the landscape would be negotiated, wouldl be the discriminating element in a distinct way for each one of them. It is through each of these facades that this relationship would extend, and far beyond their physical perimeter. The investigation has been structured into six chapters, preceded by an introduction. The first chapter outlines and analyses the backgrounds, figures and buildings most relevant to the Danish Tradition. This is to facilitate the understanding and elucidation of some of the keys to its modernity in the field of architecture, which came about with the clear intention to discover its own identity and expression. This thriving modernity is characterized by its moderate assimilation with foreign cultures with a critical eye, and finds its roots anchored in architectural tradition and its own handcraft. It is forged in the emergence of a common ideal of enormous personality which today has come to be valued as an authentic contribution to the sphere from a culture that was formerly seen as on the peripheries. What will be demonstrated is the path taken by previous generations to these works and the debate that surrounds them. The sensibilities for both the vernacular and the classic, which at first glance may seem contradictory, will dominate the debate with the same veracity and respectability. The so-called third generation of Sigfried Giedion will revive the process between the classic and the vernacular, supported in spirit by the handcraft work and by tradition, with the objective of discovering the “truth” and the “original essence” of the architectural act. The second chapter analyzes the Varming house, built by Eva and Nils Koppel 1953, which is situated in a residential area of Gentofte. This reinterprets Asplund’s vision of an interior landscape extending to the exterior, where we see a break with the conventional sturdy brick shell of the 1930s. It is the most powerful example of the union of tradition and innovation in his their residential work. Their sober forms caught between Danish Functionalism and modernity are characterized by their abstraction and clean shapes which accentuate their prismatic and brutal geometry, The displacement of the parts of which they are composed, one over the other, generate a rhythm. This is produced to varying scales and is closely linked to its forms and the selection of materials – brick and wood – that confer an organic character to the house. The building is anchored to the earth, finding solution at different levels through the study of place and topography. The result is an adaption constructed out of the landscape, in which the building gives form to the place and celebrates the experience of the natural setting. The unity of primitive structures appears to be present. It constitutes an example of “Asplund’s Promenade Idea”. Different routes of exploration within are available to the visitor, allowing for one’s own personal experience of the house, allowing in turn for the vital chance to decide. The third chapter deals with Niels Bohr’s guest pavilion. Built in 1957, it is situated in a wooded area of Tisvilde Hegn and was the architect Vilhelm Wohlert’s first building. Rooted in the Danish Tradition, it represents a renewal based on the absorption of foreign influences: American architecture and the Japanese tradition. The wooden box, perched atop a horizontal terrain, possesses the sensitive character of the living organism, ever-changing in accordance with the variations in daylight and temperature. When opened up, it creates an elongation of the interior space which extends into the surrounding nature and it expands towards the exterior space, allowing for its mobilisation. It establishes an architecture of flux. There is interest in the material, its texture and the emotional effect it inspires. The building’s proportions and dimensions are regulated by a module, which is adjusted by hand, bringing out the great unity of the building. The key to its aesthetic effect is its harmony and equilibrium, which convey serenity and beauty. The meeting with nature is the most fundamental lesson of the project, where a world of relationships softens the personality of the human being. The fourth chapter analyzes the Louisiana Museum project of 1958 in 1958. It was the first project of the Danish architects Jørgen Bo and Vilhelm Wohlert. Wohlert’s experience in California where he was visited by Bo would be essential to the development of Louisiana, where the Danish identity is fused in assimilation with other cultures, the architecture of Frank Lloyd Wright, that of the Bahía area and principally the Japanese tradition. The idea of the project was for an integrated work of art: architecture, art and landscape, which would coexist in the same space. A range of different resources would realize the residential character, such as the use of materials taken from a domestic environment, the attainment of human scale and the manner in which light was used. Flat roof plans that show their artificiality and appear to float over glassed galleries. They accentuate the strength of the horizontal plan and establish a zigzag route of marked and measured rhythm. It is a rhythm that has to do with the incarnation of nature’s pulse, which is accompanied with plays of light, as well as material vibrations of different scales, imagery which uncovers a parallel analogy with Japanese culture. Everything is coordinated along a structural frame, which involves a disciplined construction and proportion. Louisiana cherishes nature’s principle of growth, to which its connection is profound. Here is a dynamism expressed through the disposition of the building, which evokes in some projects the Japanese tradition. The white walls possess their own identity as forms in their own right. They advance, extending beyond the line of glass, moving freely along the structural line, accompanying a space that flows and in direct contact with nature that is itself in a constant state of flux. It creates a world of relationships, where dialogue exists between the landscape, art and architecture. The fifth chapter is dedicated to analyzing the Danish architect Halldor Gunnløgsson’s second house, built in 1959. It evokes both Japanese and American architecture but is principally the result of a strong will and personal artistic discipline. The flat roof suspended above a large paved platform – itself continuing the constructed terrain of the place – has great presence and casts a heavy shadow beneath. In the interior, a single space, which can at length be divided and which flows around a central space. The space flows freely, extending through the transparency of its windows which give out onto two contrasting locations: an intimate garden patio, inspiring calm and tranquillity, and the wild nature of the sea which projects the colour of sky, both in a constant state of change. The project is realized in a rigorously formal manner. A perfect balance exists between the abstraction of his structure and his project. The wooden structure, whose order extends beyond the limits of its perimeter, is formed of complete porticos of free elements. It remains exposed, maintaining a close relationship with Mies’ concept of modernity, analogous to classical architecture. The preoccupation with the aesthetic effect is paramount and nothing is improvised. But in addition to this - the combination of materials and the play of textures - there is a tactile quality, a certain eroticism, which lingers all about. The constructive precision and its refinement are close to Mies. The experience of the architectural space is universal. The influence of Japanese architecture, more conceptual than formal, is revealed in a respect for nature. It can be seen in the search for refinement through moderation, the elimination of the superfluous object that distract from the experience of place and the preoccupation with light and shade, where a certain parallel with the dark world of the Nordic winter is established. There is an understanding that space, rather than being an immaterial object defined by material surfaces, extends instead as dynamic interactions. The sixth chapter. This proposes a journey to discover some of the unfamiliar residences of most interest which were constructed in the period, and which form part of the system being investigated. Through the study of comparison and one which is geared towards various themes, diverse conclusions are drawn regarding the system being researched. The expertise in substance and form will be a distinctive characteristic in Denmark, demonstrating an approach to the culture of the Orient, both conceptual and formal, and some common interests in certain American architecture. Its teachings sensitize us to a strengthened sense of proportion, scale, materiality, texture and weight and density of space. It values both the tactile and the visual. There is a sensitivity to nature, to the human, to the landscape and to the integrity of the work.

CLIMA ORGANIZACIONAL E BURNOUT: UM ESTUDO COM SERVIDORES PÚBLICOS FEDERAIS

As condições inadequadas vivenciadas nas organizações afligem não só os trabalhadores da iniciativa privada, pois são igualmente encontradas no segmento estatal, contrariando a expectativa de que o aparato governamental eliminaria as condições insalubres e criaria outras melhores nas quais prevalecesse à promoção de saúde. Diante desse panorama questionou-se porque, uma vez que, pelo menos do ponto de vista da sociedade leiga, esses servidores estão submetidos a condições privilegiadas de trabalho. O presente estudo objetivou identificar e descrever possíveis relações entre o clima organizacional e o burnout em servidores públicos de uma instituição federal de ensino. Objetivou-se ainda descrever o clima organizacional predominante. A pesquisa realizada teve cunho quantitativo, tipo estudo de caso e exploratória. A coleta de dados deu-se por meio das escalas ECO (escala de clima organizacional), ECB (escala de caracterização do burnout) e um questionário sociodemográfico, todos os instrumentos autoaplicáveis eletronicamente disponíveis à instituição. Participaram do estudo 201 servidores públicos federais, com idade média de 37 anos, majoritariamente de nível superior e casados. Os resultados revelaram que cerca de um quarto dos participantes raramente experimentaram burnout, no entanto outra quarta parte deles frequentemente experimentaram altos níveis de burnout, resultado bastante expressivo. Os servidores perceberam clima organizacional mediano, destacando-se a boa coesão entre os colegas de trabalho e a percepção de baixa recompensa. Merece destaque a grande dispersão entre as percepções de clima, o que permite inferir haver subclimas não identificados nesta investigação, possivelmente ocasionados por uma força de clima fraca e pela participação dos servidores de unidades de ensino geograficamente distintas, geridas por gestores locais com relativa autonomia. Os resultados dos cálculos de correlação revelaram que, quanto menos os participantes percebem apoio da chefia e da organização, coesão entre colegas, e mais controle/pressão, mais exaustos se sentem, mais desumanizam as pessoas com quem tratam e mais se decepcionam no trabalho e vice-versa. Conforto físico menor está associado a maior desumanização e a mais decepção no trabalho e vice-versa; e que controle/pressão, relaciona-se positiva e fracamente com desumanização e vice-versa. Desta forma, a hipótese de que existe associação entre burnout e clima organizacional foi confirmada. Os resultados também revelaram que os servidores com burnout, perceberam pior clima organizacional que os seus pares sem burnout, confirmando a segunda hipótese. Esses servidores também se mostraram neutros quanto à percepção de apoio da chefia e conforto físico; não percebem controle pressão, nem recompensa; todavia percebem coesão entre os colegas. Esses resultados sugerem que os participantes têm se apoiado nessas relações para suportar a indiferença e ausência de estímulos experimentados no trabalho. Os resultados obtidos nesse estudo permitiram concluir que o clima organizacional é fraco, provavelmente influenciado por uma cultura organizacional fraca, explicando a heterogeneidade da percepção do clima organizacional pelos servidores. Além disso, embora haja burnout entre poucos participantes, há que se atentar que cerca de um quarto deles, encontra-se acometido desta síndrome e isto poderá contagiar os demais.

The relevance of harmonising the technical level of social housing with the urban level of the neighbourhood through the example of the 500 dwellings in Albacete

The Architecture and Household Trade Union built nearly 2,000 subsidized dwellings in Albacete from 1941 to 1971. It was the responsible entity from the end of the Civil War until the beginning of Democracy of the social policy programs in Spain. Later on, and together with the National Housing Institute, were responsible for the construction activity. Its limited budget, scarcity of technical and human resources and an urgent need for new housing developments, constituted the basis for producing a vast housing market of low construction qualities. However, thanks to the true architectonic expertise of some of the professionals, some of the developments were designed with a clear urban strategy and in direct relation with the city, which characterizes them to be studied and conserved. This is the case for the selected development for the analysis, the urban complex of the 500 dwellings in Albacete, the Hermanos Falcó Neighborhood. Designed and built between 1963, Alfonso Crespo and Adolfo Gil architects, and 1977 second reformed project by the architect Fernando Rodríguez. It is characterized by its layout on the territory, its controlled relation with the city and its different types of open blocks. Above all, its spatial and human scale strengths, directly related to the European post-war proposals, have to be emphasized; although its technical deficiencies affect the interior quality of the houses. This paper examines its virtues and failures and proposes, using current tools, its renovation. This proposal main aims are to extend its lifetime and develop the particular and urban sustainability levels.
