Buenos Aires : el Museo de las Escuelas.

En un museo argentino, las exposiciones y los objetos concretos generan experiencias sensibles, cognitivas, perceptivas, emotivas, imaginativas, asociativas, relacionales, mediante la resonancia y la maravilla. La resonancia tiene que ver con el mundo amplio al que el objeto remite al espectador. La maravilla se basa en la capacidad de determinados objetos para atraer y retener la mirada. Se considera que su patrimonio más importante es el visitante. Sus experiencias y relatos pasan a formar parte de este patrimonio de la exposición. Interesa el museo como lugar de construcción de la cultura y no sólo como un lugar de re-presentación. Por último, se aboga por el diálogo permanente entre los especialistas en educación y los especialistas en patrimonio y contenidos.

Funciones del asesoramiento escolar en los procesos de cambio educativo en la sociedad del conocimiento : un estudio de caso en escuelas secundarias de la Ciudad de Buenos Aires.

La tesis es una investigación exploratoria, de enfoque naturalista interpretativo, que presenta un diseño emergente de Estudio de Caso.. Sus objetivos generales son describir, comprender y analizar los procesos de Cambio Educativo y Asesoramiento Escolar (AE) en el contexto de la sociedad del conocimiento; identificar prácticas emergentes de AE que contribuyan la transformación escolar requerida por la sociedad del conocimiento; formular condiciones par el AE, válidas para el análisis y la intervención, que contribuyan a su eficacia en relación con la mejora escolar y con la transformación de los modelos predominantes de cambio. Los objetivos específicos del Estudio de Caso son: comprender en profundizar prácticas innovadoras de AE, en el contexto de proyectos escolares de mejora y caracterizarlas atendiendo a la dimensión ideológica, estructural y personal; identificar dimensiones de actuación y funciones del AE que contribuyan a mejorar los procesos de intervención y las estructuras de AE. El caso estudiado se refiere a los procesos de asesoramiento que acompañaron a 32 proyectos escolares de mejora en 14 escuelas secundarias públicas de la Ciudad de Buenos Aires entre 1999 y 2002.. Entre otras conclusiones se aporta un modelo de AE en el que se identifican dimensiones de actuación y fases de reconversión cognitiva. El modelo tiene al menos tres posibilidades de aplicación: el análisis y planificación de intervenciones de AE, el diseño de estructuras de AE y la formación profesional de asesores escolares..

Los servicios de psicología y asistencia social escolar en Buenos Aires.

Presentación de los servicios de psicología y asistencia social escolar en Buenos Aires. Estos Servicios dependen directamente de la Dirección de Psicología del Ministerio de Educación, por lo que distinguimos diversos aspectos como su misión, su estructuración y funciones, personal, etc. La actual Dirección de Psicología tuvo su origen en el Instituto de Psicología, creado en el año 1948; creación que colocó a la provincia de Buenos Aires como rectora en el enfoque psicopedagógico de la enseñanza.

Comparing meta-analysis and ecological-longitudinal analysis in time-series studies: a case study of the effects of air pollution on mortality in three Spanish cities

The objective of this paper is to introduce a diVerent approach, called the ecological-longitudinal, to carrying out pooled analysis in time series ecological studies. Because it gives a larger number of data points and, hence, increases the statistical power of the analysis, this approach, unlike conventional ones, allows the complementation of aspects such as accommodation of random effect models, of lags, of interaction between pollutants and between pollutants and meteorological variables, that are hardly implemented in conventional approaches. Design—The approach is illustrated by providing quantitative estimates of the short-termeVects of air pollution on mortality in three Spanish cities, Barcelona,Valencia and Vigo, for the period 1992–1994. Because the dependent variable was a count, a Poisson generalised linear model was first specified. Several modelling issues are worth mentioning. Firstly, because the relations between mortality and explanatory variables were nonlinear, cubic splines were used for covariate control, leading to a generalised additive model, GAM. Secondly, the effects of the predictors on the response were allowed to occur with some lag. Thirdly, the residual autocorrelation, because of imperfect control, was controlled for by means of an autoregressive Poisson GAM. Finally, the longitudinal design demanded the consideration of the existence of individual heterogeneity, requiring the consideration of mixed models. Main results—The estimates of the relative risks obtained from the individual analyses varied across cities, particularly those associated with sulphur dioxide. The highest relative risks corresponded to black smoke in Valencia. These estimates were higher than those obtained from the ecological-longitudinal analysis. Relative risks estimated from this latter analysis were practically identical across cities, 1.00638 (95% confidence intervals 1.0002, 1.0011) for a black smoke increase of 10 μg/m3 and 1.00415 (95% CI 1.0001, 1.0007) for a increase of 10 μg/m3 of sulphur dioxide. Because the statistical power is higher than in the individual analysis more interactions were statistically significant,especially those among air pollutants and meteorological variables. Conclusions—Air pollutant levels were related to mortality in the three cities of the study, Barcelona, Valencia and Vigo. These results were consistent with similar studies in other cities, with other multicentric studies and coherent with both, previous individual, for each city, and multicentric studies for all three cities

Narraciones compartidas: imaginarios políticos entre Charcas y Buenos Aires. (De las reformas borbónicas al proceso juntista) [Estudios]

Este artículo expone los vínculos entre las élites charqueñas y rioplatenses desde mediados del siglo XVIII hasta inicios del siglo XIX, con una mirada que incorpora la relación territorial y el vínculo de las culturas políticas que se entretejen en la conformación de ambas élites. El trabajo da cuenta de los vínculos políticos entre el mundo charqueño y el rioplatense, asumiendo ambas realidades como vinculadas e interdependientes, y muestra que dicho vínculo estuvo configurado por narraciones y preocupaciones comunes, el impacto de la crisis imperial de 1808, la resonancia de la insurgencia indígena en los años previos (La Gran Regelión de los Andes y la Rebelión de Túpac Katari) y las experiencias autonomistas del mundo andino: La Plata (Chiquisaca) y La Paz. Se utilizan los aportes de la historia conceptual y la sociología política para analizar esos complejos mundos políticos y de conformación de élites.

Eye-tracking for avatar eye-gaze and interactional analysis in immersive collaborative virtual environments

Participants' eye-gaze is generally not captured or represented in immersive collaborative virtual environment (ICVE) systems. We present EyeCVE. which uses mobile eye-trackers to drive the gaze of each participant's virtual avatar, thus supporting remote mutual eye-contact and awareness of others' gaze in a perceptually unfragmented shared virtual workspace. We detail trials in which participants took part in three-way conferences between remote CAVE (TM) systems linked via EyeCVE. Eye-tracking data was recorded and used to evaluate interaction, confirming; the system's support for the use of gaze as a communicational and management resource in multiparty conversational scenarios. We point toward subsequent investigation of eye-tracking in ICVEs for enhanced remote social-interaction and analysis.

Sociodemographic determinants of diet quality of the EU elderly: a comparative analysis in four countries

Objective: To investigate the sociodemographic determinants of diet quality of the elderly in four EU countries. Design: Cross-sectional study. For each country, a regression was performed of a multidimensional index of dietary quality v. sociodemographic variables. Setting In Finland, Finnish Household Budget Survey (1998 and 2006); in Sweden, SNAC-K (2001–2004); in the UK, Expenditure & Food Survey (2006–07); in Italy, Multi-purpose Survey of Daily Life (2009). Subjects: One- and two-person households of over-50s (Finland, n 2994; UK, n 4749); over-50 s living alone or in two-person households (Italy, n 7564); over-60 s (Sweden, n 2023). Results: Diet quality among the EU elderly is both low on average and heterogeneous across individuals. The regression models explained a small but significant part of the observed heterogeneity in diet quality. Resource availability was associated with diet quality either negatively (Finland and UK) or in a non-linear or non-statistically significant manner (Italy and Sweden), as was the preference for food parameter. Education, not living alone and female gender were characteristics positively associated with diet quality with consistency across the four countries, unlike socio-professional status, age and seasonality. Regional differences within countries persisted even after controlling for the other sociodemographic variables. Conclusions: Poor dietary choices among the EU elderly were not caused by insufficient resources and informational measures could be successful in promoting healthy eating for healthy ageing. On the other hand, food habits appeared largely set in the latter part of life, with age and retirement having little influence on the healthiness of dietary choices.

Structure, Dynamics, and RNA Interaction Analysis of the Human SBDS Protein

Shwachman-Bodian-Diamond syndrome is an autosomal recessive genetic syndrome with pleiotropic phenotypes, including pancreatic deficiencies, bone marrow dysfunctions with increased risk of myelodysplasia or leukemia, and skeletal abnormalities. This syndrome has been associated with mutations in the SBDS gene, which encodes a conserved protein showing orthologs in Archaea and eukaryotes. The Shwachman-Bodian-Diamond syndrome pleiotropic phenotypes may be an indication of different cell type requirements for a fully functional SBDS protein. RNA-binding activity has been predicted for archaeal and yeast SBDS orthologs, with the latter also being implicated in ribosome biogenesis. However, full-length SBDS orthologs function in a species-specific manner, indicating that the knowledge obtained from model systems may be of limited use in understanding major unresolved issues regarding SBDS function, namely, the effect of mutations in human SBDS on its biochemical function and the specificity of RNA interaction. We determined the solution structure and backbone dynamics of the human SBDS protein and describe its RNA binding site using NMR spectroscopy. Similarly to the crystal structures of Archaea, the overall structure of human SBDS comprises three well-folded domains. However, significant conformational exchange was observed in NMR dynamics experiments for the flexible linker between the N-terminal domain and the central domain, and these experiments also reflect the relative motions of the domains. RNA titrations monitored by heteronuclear correlation experiments and chemical shift mapping analysis identified a classic RNA binding site at the N-terminal FYSH (fungal, Yhr087wp, Shwachman) domain that concentrates most of the mutations described for the human SBDS.

Governança democrática dos recursos hídricos na região metropolitana de São Paulo : propostas a partir da experiência da região metropolitana de Buenos Aires

A Região Metropolitana de São Paulo está vivendo uma profunda crise de seus recursos hídricos, que expõe as fragilidades da atual governança, e nos convida a uma reflexão dos nós críticos que impedem um serviço mais eficiente. O presente trabalho aprofunda a governança, a gestão e a situação atual do saneamento, com base na experiência da Região Metropolitana de Buenos Aires, que vivenciou forte crise na cobertura de água e esgoto, além da contaminação das bacias. Em um processo de privatização que agravou a crise hídrica, a opção para a Grande Buenos Aires foi a reestatização e a busca por uma governança democrática, que envolve diversos entes federativos. O grande diferencial é a instituição de uma agência de planejamento, na qual o ente federal, provincial, Cidade de Buenos Aires e todos os municípios da região metropolitana, deliberam conjuntamente os projetos prioritários, vinculando a empresa prestadora do serviço. Ademais, a vivência da gestão da bacia Matanza Riachuelo apresenta governança colegiada pelos entes federativos e possui competência multidisciplinar, superando os entraves decorrentes dos arranjos governamentais e intergovernamentais para o enfrentamento da complexidade para gestão da bacia. Propõem-se, ao final, um plano de melhorias para a gestão dos recursos hídricos, com propostas de curto, médio e longo prazos. Como medida de curto prazo sugere-se a criação de uma Agência Metropolitana das Águas com o objetivo de planejar e implantar políticas públicas voltadas ao enfrentamento do problema hídrico, rompendo com o imobilismo dos entes federativos frente à crise hídrica, com órgão de deliberação colegiado, Municípios integrantes, Estado e sociedade civil na busca constante de soluções de interesse comum, cujas deliberações vinculariam a empresa fornecedora do serviço. Em médio prazo, recomenda-se discussão pública do modelo da empresa concessionária, além da revisão do planejamento e de ações de alocação de recursos feitos pela SABESP. Ao final, como medida de longo prazo, mister a elaboração de um Plano Diretor Metropolitano que cuide conjuntamente de medidas da captação, tratamento e cobertura de água e esgoto, e que promova a sustentabilidade socioambiental e integração dos municípios para melhor uso do espaço urbano. A adoção de uma governança democrática das águas na RMSP propiciará um cenário possível para as mudanças necessárias no âmbito da gestão dos recursos hídricos. A sociedade deve ser a grande responsável pelo destino da água, não devendo tão nobre missão ficar a cargo de quem tem interesse em transformá-la num bem de consumo privado.
