Pulperos rurales: entre la vida privada y la pública

Este trabajo estudia la vida privada del pulpero rural de la campaña de Buenos Aires y las actividades que desarrolla cuando no se encuentra frente a su negocio. A través del análisis de testamentos e inventarios de pulperos rurales de Buenos Aires de fines del siglo XVIII y principios del XIX el estudio intenta penetrar en la intimidad y en las actividades alternativas que desempeñaban. El trabajo logra comprobar la existencia de un espacio protegido de la intromisión pública. Si bien la frontera que separaba ambos territorios muchas veces aparecía desfigurada, el espacio privado ha sido conquistado en mayor o menor medida por el pulpero rural. Con ello este artículo cuestiona la visión de rusticidad general que envolvía a la vida en la campaña y ubica a los pulperos dentro de los sectores medios que poblaban la campaña.

Producción en masa, economía monetaria y vitalidad comercial del Mediterráneo

Se argumenta que la arqueología y la historia monetaria reúnen entre sí el potencial para proyectar una imagen de la economía romana muy diferente a la que sugieren los estereotipos minimalistas. Se discuten las implicancias de esta argumentación para el período tardoantiguo en particular, rechazando el catastrofismo con el que Rostovtzeff concluía su célebre historia del temprano imperio. En el imperio tardío la fortaleza de los intereses privados se mantuvo tan firme como siempre, en una economía caracterizada por la integración de los negocios públicos y privados antes que por un supuesto conflicto o antagonismo entre ambos. El imperio de Oriente conservó estas tendencias en forma pura, con niveles sostenidos de comercio y circulación monetaria hasta las décadas centrales del siglo VII. En este trabajo se argumenta que pensar en términos de ciclos económicos sería para los historiadores más razonable que la patología convencional de la "declinación", "decadencia", etc. Este patrón es notablemente evidente en la historia económica bizantina, marcada por abruptas fluctuaciones entre los siglos V y XII.

Testimonios de un Pasado Imperfecto : Vida Cotidiana de Mujeres bajo Dictadura en Valparaíso y Viña del Mar, Chile 1980-1987

Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987. La metodología se radica firmemente en el método etnográfico con entrevistas semi-abiertas y el análisis del discurso de los relatos. En la metáfora de la arpillera (un tapiz anónimo cosido en lona ensamblado a partir de piezas de tela que muestra escenas de la vida cotidiana o protesta la dictadura de Pinochet), trozos y pedazos de experiencia se juntan en el encima de la lona de la historia para dar forma al testimonio de vida la vida cotidiana. Este proyecto se centra en tres aspectos diferentes de la relación entre el Estado autoritario y la vida cotidiana: las técnicas de gobernabilidad (macro), narraciones de silencio y miedo (micro) y trayectorias narrados (espacial), el último inspirado por el ensayo Halbwachs en caminar por la ciudad. Para cerrar, la relevancia del estudio se destaca por el intento de comprender el efecto de un estado autoritario en el sujeto femenino y las respuestas y adaptaciones que las mujeres chilenas adoptaron en la vida privada y pública mediada por la violencia y el miedo bajo dictadura. La dialéctica del acontecimiento y la rutina de la vida cotidiana bajo la dictadura se unen en las memorias narradas, mediada por el presente vivido, lo cual permite una reflexión sobre la cuestión de la alteridad en la sociedad chilena.Este proyecto de investigación se caracteriza como estudio histórico-etnográfica basado en estudios de casos de la vida cotidiana de nueve mujeres en Valparaíso y Viña del Mar durante la dictadura chilena, analizando el testimonio de los efectos del régimen autoritario en la vida cotidiana de estas mujeres chilenas entre 1980 y 1987.

Aeronautical Information Geoservices

Aeronautical charts underlie the representation of aeronautic geographic information that supports pilots in flight. Nevertheless, charts become complex due to the high density of data and the different kinds that support each phase of flight. These features make difficult using them on board. After conducting a study that aims to understand and to evaluate pilot’s needs related to Geographic Information, it is proposed a solution to implement a platform based on geographic information standards (OGC, ISO) and supported by a distributed Web architecture. This platform facilitates the use, retrieval, updating of information and its exchange among different institutions through private and public users. As a first element to ensure interoperability and the harmonisation of information, we propose an aeronautical metadata profile that sets guidelines and elements for its description. This profile meets the standards set by ICAO, Eurocontrol and ISO. The platform offers three levels of access to data through different types of devices and user profiles. This paper suggests an alternative and reliable way for distributing aeronautical geoinformation, focusing on specific functions or displaying and querying.

Geoservices for Aeronautical Navigation

Aeronautical charts underlie the representation of aeronautic geographic information that supports pilots in flight. Nevertheless, the charts become complex due to the high density of data and the different kinds of charts that support each phase of flight. These features make difficult using them on board. After conducting a study, with civil Spaniard pilots, that aims to understand and to evaluate their needs related to Geographic Information, it is proposed a solution to implement a platform based on geographic information standards (OGC, ISO) and supported by a distributed Web architecture. This platform facilitates the use, retrieval, updating of information and its exchange among different institutions through private and public users. As a first element to ensure interoperability of information, we suggest an aeronautical metadata profile that sets guidelines and elements for its description. The metadata profile meets the standards set by ICAO, Eurocontrol and ISO. The platform offers three levels of access to data through different types of devices and user profiles. Thus, aeronautical institutions could edit data while pilot is on board accessing digital aeronautical charts through a laptop or Table PC. This paper suggests an alternative and reliable way for distributing aeronautical geoinformation, focusing on specific functions or displaying and querying.

A federated repository for PaaS components in a multi-cloud environment

Cloud computing has seen an impressive growth in recent years, with virtualization technologies being massively adopted to create IaaS (Infrastructure as a Service) public and private solutions. Today, the interest is shifting towards the PaaS (Platform as a Service) model, which allows developers to abstract from the execution platform and focus only on the functionality. There are several public PaaS offerings available, but currently no private PaaS solution is ready for production environments. To fill this gap a new solution must be developed. In this paper we present a key element for enabling this model: a cloud repository based on the OSGi component model. The repository stores, manages, provisions and resolves the dependencies of PaaS software components and services. This repository can federate with other repositories located in the same or different clouds, both private and public. This way, dependencies can be fulfilled collaboratively, and new business models can be implemented.

El Poblado Dirigido de Caño Roto: Dialéctica entre morfología urbana y tipología edificatoria

La tesis doctoral titulada “El Poblado Dirigido de Caño Roto. Dialéctica entre morfología urbana y tipología edificatoria” analiza el poblado de Caño Roto, un vecindario de vivienda social construido en Madrid entre 1957 y 1963, a partir de la relación entre la edificación y la forma urbana resultante. También, la investigación desarrolla un análisis historiográfico de la obra así como de las condiciones políticas, sociales, económicas y normativas existentes en el momento de su realización, para concluir con un estudio comparativo entre éste y otros proyectos análogos al poblado en aspectos como el marco temporal y geopolítico, los planteamientos urbanísticos y algunas soluciones tipológicas y constructivas. El trabajo pretende, por un lado, profundizar en el conocimiento que se tiene actualmente de esta obra, considerada por muchos como una de las más relevantes de la arquitectura española contemporánea, y, por otro, extraer a partir de su estudio, pautas, criterios y estrategias de diseño urbano que puedan ser extrapolables al proyecto contemporáneo; a fin de superar los actuales, pero obsoletos, modelos de desarrollo. No obstante, sabemos que cualquier respuesta que plantee una vuelta al pasado está condenada al fracaso. Las circunstancias cambian y, en consecuencia, las soluciones no pueden ser las mismas. Pero si las respuestas ya no nos sirven, las preguntas siguen siendo válidas. Quién es el protagonista del diseño urbano en Caño Roto. Cómo conviven el tráfico peatonal y el rodado. Cuál es la densidad del barrio. Cómo se articulan los usos residencial, comercial y dotacional. De qué manera se organiza el tejido urbano. Qué relación existe entre los tipos edificatorios y la morfología urbana resultante; y entre los espacios de uso privado o restringido y los de uso público. Partimos de la hipótesis de que los análisis, reflexiones y resultados derivados de interrogar al poblado de Caño Roto acerca de estas, y otras muchas, cuestiones nos permitirán alcanzar un entendimiento global de la complejidad urbana y nos revelarán, además, propuestas y soluciones que contribuyan a mejorar la calidad de nuestras ciudades; ahora y en adelante. ABSTRACT The thesis entitled “El Poblado Dirigido de Caño Roto. Dialéctica entre morfología urbana y tipología edificatoria” [Poblado Dirigido of Caño Roto. Dialectic between urban morphology and typology] analyzes Caño Roto, a social housing neighborhood built in Madrid between 1957 and 1963, from the relationship between buildings and the resulting urban form. Also, this research develops a historiographical analysis of this project as well as the social, political, financial and legislative conditions present at time of its construction. This thesis concludes with a comparative study with other similar projects in temporal and geopolitical framework, urban approaches and some typological and constructive solutions. The research aims, on the one hand, to expand the current knowledge about Caño Roto, considered by many as one of the most important project at Spanish contemporary architecture; and, on the other hand, deducing from the study guidelines, criteria and strategies of urban design which can be extrapolated to contemporary architecture and urbanism. This way, we will be able to overcome current, but obsolete development models. However, we know that any response that suggests coming back to the past is destined to failure. Circumstances change and, consequently, solutions cannot be the same. But if the answers do not serve, questions are still right. Who is the protagonist of Caño Roto urban design? How do pedestrian and road traffic coexist together? What is the neighborhood’s density? How are residential, commercial and endowment uses articulated? How is urban fabric organized? What is the relationship between building types and the resulting urban morphology; and between private and public spaces? We start from the hypothesis that analysis, reflections and results arising from questioning Caño Roto about these, and many others, issues will enable us to have a comprehensive understanding of urban complexity, and they will also reveal proposals and solutions which help us to improve the quality of our cities; from now on.

Spatial divisions of society

The encounter of architecture and urbanism with parcelisation is marked with the sign of a historical debt. Parcelisation is a tremendously powerful design tool. Architecture and urban planning attest to its capacity to shape sociospatial relations across a range of scales and contexts. From Renaissance palazzi to modernist slabs, from nation-wide agrarian reforms and Haussmann’s Paris to Christopher Alexander’s new theory of urban design and Michael Webb’s Suitaloon — most of the historical revolutions and experimental projects that have shaken these fields have relied, consciously or not, on a critique and restructuration of inherited divisions of land and space. The layout of parcel patterns has a series of implications including forms of property, the divide between private and public realms, the distribution of spatial contents and uses through zoning, typological decisions and so forth. The behaviour of any urban structure depends on the tissue of plots that configures the urban fabric and many of the challenges urban design faces today —complexity, urban vitality, social equality, etc.— hinge upon the forms of land division and distribution we adopt.

Energías renovables en el sistema marítimo portuario : aprovechamiento energétio de los molinos de marea

Desde el siglo VIII hasta prácticamente el siglo XX, los molinos de marea han sido una fuente de desarrollo de las zonas en las que estaban implantados. En toda la costa atlántica de Europa, y posteriormente en América, se desarrollaron estos ingenios conectados por su naturaleza con los puertos. En ellos se procesaban materia prima que tenía su origen o destino en dichos puertos. La aparición de otras fuentes de energía más económicas y eficaces supuso la decadencia paulatina de estos ingenios, hasta la práctica desaparición de un buen número de ellos. En los últimos años, tanto instituciones privadas como públicas, especialmente ayuntamientos han mostrado un interés en conservar estos ingenios ya sea como edificación singular en el que se desarrollen distintos negocios, o como museos o “centros de interpretación” en los que se explica el funcionamiento del molino y su relación con la comarca de influencia. Este nuevo interés por el tema, unido a la necesidad de buscar nuevas fuentes de energías renovables para dar cumplimento a las condiciones del Tratado de Kyoto motivan la necesidad de un estudio de la aplicación de la energía minihidráulica a los antiguos molinos. En el presente documento se ha procedido en primer lugar a describir la historia de los molinos de marea y a continuación a localizarlos en cada provincia para identificar los posibles puntos de producción de energía. Seguidamente se procedió a identificar los diferentes tipos de turbinas aplicables a estos casos, de los que se han elegido dos de ellos, uno de ellos consolidado y el otro en fase experimental, para determinar y analizar la tendencia de determinadas magnitudes financieras en función de la carrera de marea. Las conclusiones resultantes de este análisis han sido que el sistema de funcionamiento mediante el flujo de la marea es menos productivo que mediante reflujo y que la altura de marea en las costas españolas limita considerablemente la rentabilidad de la inversión. Esta circunstancia obliga a hacer un estudio de viabilidad muy detallado de cada uno de los casos. Las investigaciones futuras en este campo se deben encaminar hacia el desarrollo de un nuevo tipo de miniturbina con una mayor regulación para obtener un mayor rendimiento, teniendo en cuenta, además, que el estuario de un molino de marea puede ser además un excelente banco de pruebas. Por otro lado, la posible producción de energía puede ser un elemento a estudiar dentro de un sistema de generación distribuida en el ámbito de una smart-city. From the eighth century until practically the twentieth century, the tide mills have been a source of development of the areas in which they were implanted. Across the Atlantic coast of Europe, and subsequently in America, these devices were developed and connected by its nature with the nearby ports. In these places the raw material, with its origin and destination from these ports, were processed. The emergence of other sources of energy more economic and efficient caused the gradual decline of these devices which led to the disappearance of a large number of them. In recent years, both private and public institutions, especially municipalities, have shown interest in preserving these devices as singular buildings, or as museums or "visitor centers" where the process of milling is explained and also its relationship with the region of influence. This renewed interest in the subject, coupled with the need of finding new sources of renewable energy in order to comply with the conditions of the Kyoto Treaty, has created the need for a study of the possible implementation of small hydro power in the old mills. In the present document, first we have proceeded to describe the history of the tide mills and afterwards we have located them in the Spanish provinces to identify the possible locations of energy generation. In the next step, we proceeded to identify the different types of turbines suitable to these cases, and we have been selected two of them. The first one is consolidated and the second one is in an experimental phase. With these pair of turbines we have determined and analyzed the outcome of certain financial data depending on the tidal range. The conclusions drawn from this analysis are that operating the system by the flow tide is less productive than by ebb tide. The limited height of tide in the Spanish coast considerably limits the return on investment. This outcome forces potential investors to make a very detailed analysis of each case study. Future researches in this field should be guided towards the development of a new type of mini turbine with more regulation for a higher performance, taking into account also that the basin of a tidal mill can also be an excellent test place. Furthermore, the potential energy output can be a factor to consider in a distributed generation system within a smart city.

Entre: de repente, sin fin, lo innombrable

Etiquetamos para reducir nuestra incertidumbre; clasificamos en base a términos opuestos para poder entender. El universo y el espacio construido en particular, se explican desde una arquitectónica dual: dentro – fuera, arriba – abajo, derecha – izquierda, día – noche, hombre – mujer. Lo que nos diferencia como grupo, raza o género, distinguiendo los modos de vivir, las ideologías y las teorías, es la relación que establecemos entre los términos opuestos: entre lo individual y lo colectivo, lo privado y lo público, la imaginación y la realidad, la identidad y la otredad, el orden y el caos, el deseo y la saciedad. El afán clasificatorio dicotómico de la realidad que la modernidad lleva a su extremo, hiere la vida: la mutua exclusión de los opuestos elimina la distancia, el espacio-tiempo entre ambos, que es donde la vida se sitúa. La concepción dual que rige nuestro conocimiento contamina también la relación entre los arquitectos y la sociedad, siendo la causa del ambiente tóxico que envuelve al habitante que ya no se identifica con los lugares que habita. Puede que sea oportuno pasar del pensamiento binario a una lógica de lo intersticial que abandone la dualidad para instalarse en el Entre; los arquitectos serían mediadores entre el poder y la vida, sintiendo el Entre como el transcurso de la vida y la potencia de interacción: los lugares ambiguos e intermedios, es donde sucede el encuentro entre los términos, entre arquitectos y habitantes, entre la imaginación y la realidad, entre tú y yo. ABSTRACT We label to reduce our uncertainty; we classify based on opposites to understand. The universe and all constructed space in particular, are explained from a dual architecture: inside - out, up - down, right - left, day - night, male - female, black - white. What differentiate us as a group, race, gender, distinguishing the lifestyles, ideologies and theories, is how we draw the relation between the opposites: between the individual and the collective, private and public, imagination and reality , identity and otherness, order and disorder, desire and satiety. The dichotomous classification of reality that modernity carried to its extreme, hurts life: the mutual exclusion of opposites eliminates the distance, the space-time between the two, which is where life is located. The dual conception that governs our knowledge has also contaminated the relationship between architect and society, being the cause of the toxic environment that surrounds the inhabitant who no longer identify himself with the places he inhabit. It may be appropriate pass from binary thinking to a logic of the interstitial which abandon duality to settle in Between; architect then will be the mediator between authorities and life, sensing the Between as a flowing of life a potency of interaction rather than a separation between the extremes; ambiguous, in –between, places are where the encounter between opposites happens, between the architect and the inhabitant, between imagination and reality, between you and me.

Sobre a evasão estudantil na Escola Politécnica da Universidade de São Paulo: identificação e possíveis causas.

A evasão estudantil afeta as universidades, privadas e públicas, no Brasil, trazendo-lhes prejuízos financeiros proporcionais à incidência, respectivamente, de 12% e de 26% no âmbito nacional e de 23% na Universidade de São Paulo (USP), razão pela qual se deve compreender as variáveis que governam o comportamento. Neste contexto, a pesquisa apresenta os prejuízos causados pela evasão e a importância de pesquisá-la na Escola Politécnica da USP (EPUSP): seção 1, desenvolve revisão bibliográfica sobre as causas da evasão (seção 2) e propõe métodos para obter as taxas de evasão a partir dos bancos de dados do Governo Federal e da USP (seção 3). Os resultados estão na seção 4. Para inferir sobre as causas da evasão na EPUSP, analisaram-se bancos de dados que, descritos e tratados na seção 5.1, contêm informações (P. Ex.: tipo de ingresso e egresso, tempo de permanência e histórico escolar) de 16.664 alunos ingressantes entre 1.970 e 2.000, bem como se propuseram modelos estatísticos e se detalharam os conceitos dos testes de hipóteses 2 e t-student (seção 5.2) utilizados na pesquisa. As estatísticas descritivas mostram que a EPUSP sofre 15% de evasão (com maior incidência no 2º ano: 24,65%), que os evadidos permanecem matriculados por 3,8 anos, que a probabilidade de evadir cresce após 6º ano e que as álgebras e os cálculos são disciplinas reprovadoras no 1º ano (seção 5.3). As estatísticas inferenciais demonstraram relação entre a evasão - modo de ingresso na EPUSP e evasão - reprovação nas disciplinas do 1º ano da EPUSP, resultados que, combinados com as estatísticas descritivas, permitiram apontar o déficit vocacional, a falta de persistência, a falta de ambientação à EPUSP e as deficiências na formação predecessora como variáveis responsáveis pela evasão (seção 5.4).
