Gestión intelectual de las prácticas comunicativas en arquitectura : S, M, L, XL, el gran evento = The intellectual management of communication practices in architecture : S, M, L, XL, the big event

La tesis doctoral se centra en la posibilidad de entender que la práctica de arquitectura puede encontrar en las prácticas comunicativas un apoyo instrumental, que sobrepasa cualquier simplificación clásica del uso de los medios como una mera aplicación superficial, post-producida o sencillamente promocional. A partir de esta premisa se exponen casos del último cuarto del siglo XX y se detecta que amenazas como el riesgo de la banalización, la posible saturación de la imagen pública o la previsible asociación incorrecta con otros individuos en presentaciones grupales o por temáticas, han podido influir en un crecimiento notable de la adquisición de control, por parte de los arquitectos, en sus oportunidades mediáticas. Esto es, como si la arquitectura hubiera empezado a superar y optimizar algo inevitable, que las fórmulas expositivas y las publicaciones, o más bien del exponer(se) y publicar(se), son herramientas disponibles para activar algún tipo de gestión intelectual de la comunicación e información circulante sobre si misma. Esta práctica de “autoedición” se analiza en un periodo concreto de la trayectoria de OMA -Office for Metropolitan Architecture-, estudio considerado pionero en el uso eficiente, oportunista y personalizado de los medios. Así, la segunda parte de la tesis se ocupa del análisis de su conocida monografía S,M,L,XL (1995), un volumen que contó con gran participación por parte de sus protagonistas durante la edición, y de cuyo proceso de producción apenas se había investigado. Esta publicación señaló un punto de inflexión en su género alterando todo formato y restricciones anteriores, y se ha convertido en un volumen emblemático para la disciplina que ninguna réplica posterior ha podido superar. Aquí se presenta a su vez como el desencadenante de la construcción de un “gran evento” que concluye en la transformación de la identidad de OMA en 10 años, paradójicamente entre el nacimiento de la Fundación Groszstadt y el arranque de la actividad de AMO, dos entidades paralelas clave anexas a OMA. Este planteamiento deviene de cómo la investigación desvela que S,M,L,XL es una pieza más, central pero no independiente, dentro de una suma de acciones e individuos, así como otras publicaciones, exposiciones, eventos y también artículos ensayados y proyectos, en particular Bigness, Generic City, Euralille y los concursos de 1989. Son significativos aspectos como la apertura a una autoría múltiple, encabezada por Rem Koolhaas y el diseñador gráfico Bruce Mau, acompañados en los agradecimientos de la editora Jennifer Sigler y cerca de una centena de nombres, cuyas aportaciones no necesariamente se basan en la construcción de fragmentos del libro. La supresión de ciertos límites permite superar también las tareas inicialmente relevantes en la edición de una publicación. Un objetivo general de la tesis es también la reflexión sobre relaciones anteriormente cuestionadas, como la establecida entre la arquitectura y los mercados o la economía. Tomando como punto de partida la idea de “design intelligence” sugerida por Michael Speaks (2001), se extrae de sus argumentos que lo esencial es el hallazgo de la singularidad o inteligencia propia de cada estudio de arquitectura o diseño. Asimismo se explora si en la construcción de ese tipo de fórmulas magistrales se alojaban también combinaciones de interés y productivas entre asuntos como la eficiencia y la creatividad, o la organización y las ideas. En esta dinámica de relaciones bidireccionales, y en ese presente de exceso de información, se fundamenta la propuesta de una equivalencia más evidenciada entre la “socialización” del trabajo del arquitecto, al compartirlo públicamente e introducir nuevas conversaciones, y la relación inversa a partir del trabajo sobre la “socialización” misma. Como si la consciencia sobre el uso de los medios pudiera ser efectivamente instrumental, y contribuir al desarrollo de la práctica de arquitectura, desde una perspectiva idealmente comprometida e intelectual. ABSTRACT The dissertation argues the possibility to understand that the practice of architecture can find an instrumental support in the practices of communication, overcoming any classical simplification of the use of media, generally reduced to superficial treatments or promotional efforts. Thus some cases of the last decades of the 20th century are presented. Some threats detected, such as the risk of triviality, the saturation of the public image or the foreseeable wrong association among individuals when they are introduced as part of thematic groups, might have encouraged a noticeable increase of command taken by architects when there is chance to intervene in a media environment. In other words, it can be argued that architecture has started to overcome and optimize the inevitable, the fact that exhibition formulas and publications, or simply the practice of (self)exhibition or (self)publication, are tools at our disposal for the activation of any kind of intellectual management of communication and circulating information about itself. This practice of “self-edition” is analyzed in a specific timeframe of OMA’s trajectory, an office that is considered as a ground-breaking actor in the efficient and opportunistic use of media. Then the second part of the thesis dissects their monograph S,M,L,XL (1995), a volume in which its main characters were deeply involved in terms of edition and design, a process barely analyzed up to now. This publication marked a turning point in its own genre, disrupting old formats and traditional restrictions. It became such an emblematic volume for the discipline that none of the following attempts of replica has ever been able to improve this precedent. Here, the book is also presented as the element that triggers the construction of a “big event” that concludes in the transformation of OMA identity in 10 years. Paradoxically, between the birth of the Groszstadt Foundation and the early steps of AMO, both two entities parallel and connected to OMA. This positions emerge from how the research unveils that S,M,L,XL is one more piece, a key one but not an unrelated element, within a sum of actions and individuals, as well as other publications, exhibitions, articles and projects, in particular Bigness, Generic City, Euralille and the competitions of 1989. Among the remarkable innovations of the monograph, there is an outstanding openness to a regime of multiple authorship, headed by Rem Koolhaas and the graphic designer Bruce Mau, who share the acknowledgements page with the editor, Jennifer Sigler, and almost 100 people, not necessarily responsible for specific fragments of the book. In this respect, the dissolution of certain limits made possible that the expected tasks in the edition of a publication could be trespassed. A general goal of the thesis is also to open a debate on typically questioned relations, particularly between architecture and markets or economy. Using the idea of “design intelligence”, outlined by Michael Speaks in 2001, the thesis pulls out its essence, basically the interest in detecting the singularity, or particular intelligence of every office of architecture and design. Then it explores if in the construction of this kind of ingenious formulas one could find interesting and useful combinations among issues like efficiency and creativity, or organization and ideas. This dynamic of bidirectional relations, rescued urgently at this present moment of excess of information, is based on the proposal for a more evident equivalence between the “socialization” of the work in architecture, anytime it is shared in public, and the opposite concept, the work on the proper act of “socialization” itself. As if a new awareness of the capacities of the use of media could turn it into an instrumental force, capable of contributing to the development of the practice of architecture, from an ideally committed and intelectual perspective.

Efficient chemo-enzymatic gluten detoxification: reducing toxic epitopes for celiac patients improving functional properties

Protein engineering of gluten, the exogenous effector in celiac disease, seeking its detoxification by selective chemical modification of toxic epitopes is a very attractive strategy and promising technology when compared to pharmacological treatment or genetic engineering of wheat. Here we present a simple and efficient chemo-enzymatic methodology that decreases celiac disease toxic epitopes of gluten proteins improving its technological value through microbial transglutaminase-mediated transamidation of glutamine with n-butylamine under reducing conditions. First, we found that using low concentrations of amine-nucleophile under non-reducing conditions, the decrease in toxic epitopes is mainly due to transglutaminase-mediated cross-linking. Second, using high amine nucleophile concentrations protein cross-linking is substantially reduced. Third, reducing conditions increase 7-fold the transamidation reaction further decreasing toxic epitopes amount. Fourth, using n-butylamine improves gluten hydrophobicity that strengthens the gluten network. These results open the possibility of tailoring gluten for producing hypoallergenic flours while still taking advantage of the unique viscoelastic properties of gluten.

AVALIAÇÃO INSTITUCIONAL NA EDUCAÇÃO BÁSICA: UMA ANÁLISE DA PRÁTICA DA EDUCAÇÃO ADVENTISTA

O tema desta dissertação é a Avaliação Institucional da Educação Básica. Para tal, faz-se a análise do processo de avaliação, com ênfase no instrumento utilizado pelas Escolas Adventistas de nível básico do estado de São Paulo, considerando que a educação adventista se tornou uma parte consistente dentro da estrutura da Igreja Adventista do Sétimo Dia. Procurou-se, neste trabalho, como objetivo geral, compreender como se configura a prática da avaliação institucional das escolas da Rede Adventista de Educação. O método da investigação incluiu análise bibliográfica dos principais teóricos da área de políticas públicas e do sistema privado bem como da avaliação institucional, seguido de exame documental do instrumento utilizado no processo de avaliação institucional. O estudo resgata a contextualização histórica do desenvolvimento da escola privada, destacando aspectos relevantes de sua relação com o Estado. Também apresenta brevemente a história da Igreja Adventista do Sétimo Dia (IASD) nos Estados Unidos (EUA) e no Brasil, de modo a situar o surgimento do sistema educacional adventista, bem como a sua filosofia de ensino, buscando conhecer as origens desse grupo religioso que há mais de um século atua no cenário educacional brasileiro. Em seguida, aborda aspectos da Avaliação Institucional. Finalmente, apresenta-se uma síntese do processo e uma descrição analítica do instrumento de avaliação institucional das escolas de nível básico da Educação Adventista. Na conclusão do trabalho, não se encontraram indícios de que o conceito adventista de avaliação educacional seja diferente do das abordagens tradicionais. Entretanto, na concepção adventista de avaliação, existe mais fortemente a preocupação de se manter um processo de avaliação contínuo e sistemático.

In vivo telomere dynamics of human hematopoietic stem cells

Aging in vivo and cell division in vitro are associated with telomere shortening. Several lines of evidence suggest that telomere length may be a good predictor of the long term replicative capacity of cells. To investigate the natural fate of chromosome telomeres of hematopoietic stem cells in vivo, we measured the telomere length of peripheral blood granulocytes from 11 fully engrafted bone marrow transplant recipients and from their respective donors. In 10 of 11 donor–recipient pairs, the telomere length was significantly reduced in the recipient and the extent of reduction correlated inversely with the number of nucleated cells infused. These data provide internally controlled in vivo evidence that, concomitantly with their proliferation, hematopoietic stem cells lose telomere length; it is possible that, as a result, their proliferative potential is reduced. These findings must be taken into account when developing new protocols in which few stem cells are used for bone marrow transplantation or for gene therapy.

Dopamine receptor regulating factor, DRRF: A zinc finger transcription factor

Dopamine receptor genes are under complex transcription control, determining their unique regional distribution in the brain. We describe here a zinc finger type transcription factor, designated dopamine receptor regulating factor (DRRF), which binds to GC and GT boxes in the D1A and D2 dopamine receptor promoters and effectively displaces Sp1 and Sp3 from these sequences. Consequently, DRRF can modulate the activity of these dopamine receptor promoters. Highest DRRF mRNA levels are found in brain with a specific regional distribution including olfactory bulb and tubercle, nucleus accumbens, striatum, hippocampus, amygdala, and frontal cortex. Many of these brain regions also express abundant levels of various dopamine receptors. In vivo, DRRF itself can be regulated by manipulations of dopaminergic transmission. Mice treated with drugs that increase extracellular striatal dopamine levels (cocaine), block dopamine receptors (haloperidol), or destroy dopamine terminals (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) show significant alterations in DRRF mRNA. The latter observations provide a basis for dopamine receptor regulation after these manipulations. We conclude that DRRF is important for modulating dopaminergic transmission in the brain.

Formação continuada e profissionalização docente na Rede Municipal de São Paulo

Essa pesquisa situa-se no âmbito da problemática da formação continuada de professores da educação básica, especialmente daqueles que trabalham nas séries iniciais do ensino fundamental. Considerando a importância da educação continuada e a diversidade de modelos e espaços de formação de professores, que são oferecidos pela Secretaria Municipal de Educação de São Paulo, a pesquisa propõe-se a investigar experiências diversas que nesse sentido foram desenvolvidas no período pós LDBEN 9394/96, tendo por objetivo principal compreender a contribuição de tais cursos para a profissionalização e a melhoria da competência docente. A metodologia é de natureza qualitativa, envolvendo dois tipos de coleta de dados: (a) documentais: textos oficiais e outros produzidos no âmbito dos programas analisados; e (b) depoimentos orais colhidos por meio de entrevistas gravadas com um grupo de 5 professoras polivalentes do Ensino Fundamental I da rede municipal de ensino de São Paulo. A análise dos dados se respalda em vários autores que sob diferentes enfoques têm teorizado sobre o trabalho e a profissão docente, dentre os quais, Nóvoa, Dubar, Tardif, Bourdoncle e Popkewitz. A articulação entre os dados empíricos e o referencial teórico foi feita por meio dos principais conceitos que orientam a investigação: profissão, profissionalização, desenvolvimento profissional, competência e saberes docente. A expectativa é a de poder contribuir com elementos novos a propósito da questão da formação continuada de professores e, também, sobre os diferentes modelos de formação propostos para a profissionalização docente, identificando as concepções que têm se incorporado à prática dos professores por meio desse processo. As análises permitiram concluir que a educação continuada pode ser um dos elementos constitutivos do processo de profissionalização docente, no entanto, sem outras ações conjuntas torna-se inviável a sua efetivação, pois esse processo está intimamente relacionado a uma gama de fatores sociais, econômicos e políticos e a níveis elevados de rigorosidade correlacionados à formação, organização e prestígio.

Plasma membrane dynamics in the Drosophila embryo

ABSTRACT Convergent extension is a highly conserved process among mammals, in which the tissue narrows in one axis, and extends across another. Tissue elongation is directed by the regulation of cell interface behaviors, which guides cell intercalation and rosette formation. Rosette formation occurs through the contraction of vertically oriented cell interfaces, and the subsequent elongation of new horizontal interfaces. It has been shown that actomyosin-generated tension functions to direct rosette formation. In this thesis, I have tested the function of regulators of F-actin networks, as well as endocytic and exocytic mechanisms, to identify new components that control interface behaviors and cell shape. I have performed a screen of F-actin regulators and nucleators, and pinpointed the specific actin nucleator dPod-1 as a candidate protein that is localized to vertical interfaces during tissue elongation. Furthermore, I have probed the function of endocytosis using the Shibire mutation, and demonstrated that endocytosis is required for vertical interface shrinking. Finally, I have used mutations in components of the Exocyst Complex and the associated protein RalA to inhibit exocytic mechanisms, in order to address their function in directing cell and tissue morphologies.

Pion-kaon scattering amplitude constrained with forward dispersion relations up to 1.6 GeV

In this work we provide simple and precise parametrizations of the existing πK scattering data from threshold up to 1.6 GeV, which are constrained to satisfy forward dispersion relations as well as three additional threshold sum rules. We also provide phenomenological values of the threshold parameters and of the resonance poles that appear in elastic scattering.

Transmission and Transport of Energy in the Western U.S. and Canada: A Law and Policy Road Map

This collection of short essays arose from the inaugural meeting of the Idaho Symposium on Energy in the West, which was held in November, 2014. The topic for this first Symposium was Transmission and Transport of Energy in the Western U.S. and Canada: A Law and Policy Road Map. The essays in this collection provide a notable introduction to the major energy issues facing the West today. Topics include: building a resilient legal architecture for western energy production; natural gas flaring; transmission planning for wind energy; utilities and rooftop solar; special considerations for western states and the Clean Power Plan; the Clean Power Plan's implications for the western grid; siting renewable energy on public lands; and implications of utility reform in New York and Hawaii for the Northwest.

Evaluación de la susceptibilidad de las laderas a sufrir inestabilidades inducidas por terremotos: aplicación a la cuenca de drenaje del río Serpis (provincia de Alicante)

Se ha realizado un análisis para estimar la susceptibilidad de las laderas, en suelos de la cuenca de drenaje del río Serpis, a sufrir inestabilidades inducidas por terremotos. Para ello, se ha utilizado el denominado método de Newmark, que ha sido convenientemente modificado para contemplar la variabilidad que, de forma natural, se observa en las propiedades geotécnicas de los materiales. En el cálculo, se ha efectuado una simulación Monte Carlo, donde todas las propiedades geotécnicas que intervienen son tratadas como variables aleatorias. Los resultados obtenidos están expresados como probabilidad de que la aceleración crítica del talud sea menor o igual que 0.1g. Las susceptibilidades más elevadas se observan cuando los materiales están secos, pero en tal caso la extensión de territorio afectado es pequeña. En cambio, cuando el suelo está saturado se observa que gran parte del territorio presenta susceptibilidad Media o Baja, incluso con pendientes de 6 – 10º, frente a susceptibilidad Muy Baja – Nula, que los caracteriza cuando se encuentra seco. Se ha analizado también la posición de las zonas de mayor susceptibilidad con respecto a elementos constructivos existentes en el área.
