The present paper presents the results of a transversal descriptive study which intended to estimate the contribution of the project “Caring for those who take care of people with disabilities” in the areas of: strength of personal and group competences, self care, life project, dexterity in the care process of people with disabilities, and communitarian auto management; that was implemented in 20 urban areas with caregivers of the city of Bogota in the year 2007. The study allowed the nresearches to acknowledge the little change perception that caregivers had in terms of self care, however, the caregivers perceived change in the four areas, although this were not statistically significant in comparison with the general population. There were only significant changes in the communitarian auto management area in 30% of the population. As a result, it is proposed that more extensive, continuous, and sustainable processes are implemented and that this process arises from contention spaces which can be created with the caregivers, from which they can be motivated to participate in other ´processes of collective and individual changes. Also there’s a need to rely on facilitators (professionals and change agents) who have stronger competences on the how to be and the how to interact competences, because there’s a need to manage the psychosocial components in this group of people. Also, we must make organizational processes and the social networks stronger, this is: collective actions are required, because disability is a social fact, and so, the individual issues are just a moment in the process of inclusion of the person with disability, his family and caregiver.

La tesis se centra en la Visión por Computador y, más concretamente, en la segmentación de imágenes, la cual es una de las etapas básicas en el análisis de imágenes y consiste en la división de la imagen en un conjunto de regiones visualmente distintas y uniformes considerando su intensidad, color o textura. Se propone una estrategia basada en el uso complementario de la información de región y de frontera durante el proceso de segmentación, integración que permite paliar algunos de los problemas básicos de la segmentación tradicional. La información de frontera permite inicialmente identificar el número de regiones presentes en la imagen y colocar en el interior de cada una de ellas una semilla, con el objetivo de modelar estadísticamente las características de las regiones y definir de esta forma la información de región. Esta información, conjuntamente con la información de frontera, es utilizada en la definición de una función de energía que expresa las propiedades requeridas a la segmentación deseada: uniformidad en el interior de las regiones y contraste con las regiones vecinas en los límites. Un conjunto de regiones activas inician entonces su crecimiento, compitiendo por los píxeles de la imagen, con el objetivo de optimizar la función de energía o, en otras palabras, encontrar la segmentación que mejor se adecua a los requerimientos exprsados en dicha función. Finalmente, todo esta proceso ha sido considerado en una estructura piramidal, lo que nos permite refinar progresivamente el resultado de la segmentación y mejorar su coste computacional. La estrategia ha sido extendida al problema de segmentación de texturas, lo que implica algunas consideraciones básicas como el modelaje de las regiones a partir de un conjunto de características de textura y la extracción de la información de frontera cuando la textura es presente en la imagen. Finalmente, se ha llevado a cabo la extensión a la segmentación de imágenes teniendo en cuenta las propiedades de color y textura. En este sentido, el uso conjunto de técnicas no-paramétricas de estimación de la función de densidad para la descripción del color, y de características textuales basadas en la matriz de co-ocurrencia, ha sido propuesto para modelar adecuadamente y de forma completa las regiones de la imagen. La propuesta ha sido evaluada de forma objetiva y comparada con distintas técnicas de integración utilizando imágenes sintéticas. Además, se han incluido experimentos con imágenes reales con resultados muy positivos.

O presente trabalho teve como ponto de partida os resultados dos rendimentos escolares apresentados pelo SAEB (Sistema de Avaliação da Educação Básica) e o SAEPE (Sistema de Avaliação Escolar de Pernambuco), frente às ações de intervenções promovidas pelas políticas públicas implementadas pelo governo de Pernambuco, através dos programas de formação continuada, direcionados na perspectiva de reverter os baixos índices do rendimento escolar, o que nos possibilitou a delinear objetivos que nos permitissem a identificar a relação entre os indicadores do SAEB, SAEPE e Programas de Formação Continuada no redimensionamento do saber fazer docente e implicações na melhoria do desempenho docente, bem como identificar limites e possibilidades da formação na melhoria do desempenho docente, em razão dos indicadores apresentados. As transformações do mundo têm interferido de forma contundente no campo da educação, bem como nos vários aspectos da gestão educacional, escolar, curricular e particularmente na formação continuada, com vistas no desempenho docente, tendo como objeto crescente a atenção dos pesquisadores com atuação na educação. As políticas educacionais no Brasil vêm demonstrado preocupação com a qualidade do ensino ofertada pela escola pública, decorrente das pressões dos organismos internacionais, que veem na educação a solução dos problemas enfrentados por um mundo cada vez mais globalizado, de transformações e descobertas tecnológicas que caracterizam hoje, a chamada sociedade do conhecimento. Tal contexto, em que a escola pública brasileira se encontrava, mobilizou os gestores a buscarem ações de intervenção no sentido de reverter o quadro tão comprometedor que o ensino público da Educação Básica brasileira se apresentava. O repensar das práticas pedagógicas vivenciadas no contexto escolar, recai sobre o professor, a responsabilidade do resultado que a escola apresenta. Falar da prática pedagógica recai necessariamente na formação inicial e continuada desse professor. Para sua realização utilizou-se uma abordagem quantitativa e qualitativa. As técnicas de coleta de dados foram aplicação de questionários a 100 professores da educação básica da rede pública, entrevistas com cinco formadores e análise dos documentos relacionados com a política de formação continuada. O estudo demonstrou que o modelo proposto, pouco tem contribuído para o desenvolvimento profissional docente, não envolvendo, portanto, o professor diretamente no processo formativo, com exceção dos que participam de alguns programas (SAEB / SAEPE) que visam diretamente à melhoria dos índices de aprendizagem em língua portuguesa e matemática, na perspectiva de que a formação os instrumentalize a aplicar técnicas, que a formação continuada não atende nem suas necessidades, nem da escola. Os demais professores só se encontram uma vez por ano, em estilo de grande evento, enquanto as formações ocorrem de forma desarticulada e fragmentada. Em consequência, foram apresentadas algumas reflexões no intuito de provocar e contribuir na revisão da concepção de formação continuada vivenciada pelos professores da rede pública do ensino de Pernambuco.

The representation of the diurnal cycle in the Hadley Centre climate model is evaluated using simulations of the infrared radiances observed by Meteosat 7. In both the window and water vapour channels, the standard version of the model with 19 levels produces a good simulation of the geographical distributions of the mean radiances and of the amplitude of the diurnal cycle. Increasing the vertical resolution to 30 levels leads to further improvements in the mean fields. The timing of the maximum and minimum radiances reveals significant model errors, however, which are sensitive to the frequency with which the radiation scheme is called. In most regions, these errors are consistent with well documented errors in the timing of convective precipitation, which peaks before noon in the model, in contrast to the observed peak in the late afternoon or evening. When the radiation scheme is called every model time step (half an hour), as opposed to every three hours in the standard version, the timing of the minimum radiance is improved for convective regions over central Africa, due to the creation of upper-level layer-cloud by detrainment from the convection scheme, which persists well after the convection itself has dissipated. However, this produces a decoupling between the timing of the diurnal cycles of precipitation and window channel radiance. The possibility is raised that a similar decoupling may occur in reality and the implications of this for the retrieval of the diurnal cycle of precipitation from infrared radiances are discussed.

Simulations of the top-of-atmosphere radiative-energy budget from the Met Office global numerical weather-prediction model are evaluated using new data from the Geostationary Earth Radiation Budget (GERB) instrument on board the Meteosat-8 satellite. Systematic discrepancies between the model simulations and GERB measurements greater than 20 Wm-2 in outgoing long-wave radiation (OLR) and greater than 60 Wm-2 in reflected short-wave radiation (RSR) are identified over the period April-September 2006 using 12 UTC data. Convective cloud over equatorial Africa is spatially less organized and less reflective than in the GERB data. This bias depends strongly on convective-cloud cover, which is highly sensitive to changes in the model convective parametrization. Underestimates in model OLR over the Gulf of Guinea coincide with unrealistic southerly cloud outflow from convective centres to the north. Large overestimates in model RSR over the subtropical ocean, greater than 50 Wm-2 at 12 UTC, are explained by unrealistic radiative properties of low-level cloud relating to overestimation of cloud liquid water compared with independent satellite measurements. The results of this analysis contribute to the development and improvement of parametrizations in the global forecast model.

Previous assessments of the impacts of climate change on heat-related mortality use the "delta method" to create temperature projection time series that are applied to temperature-mortality models to estimate future mortality impacts. The delta method means that climate model bias in the modelled present does not influence the temperature projection time series and impacts. However, the delta method assumes that climate change will result only in a change in the mean temperature but there is evidence that there will also be changes in the variability of temperature with climate change. The aim of this paper is to demonstrate the importance of considering changes in temperature variability with climate change in impacts assessments of future heat-related mortality. We investigate future heatrelated mortality impacts in six cities (Boston, Budapest, Dallas, Lisbon, London and Sydney) by applying temperature projections from the UK Meteorological Office HadCM3 climate model to the temperature-mortality models constructed and validated in Part 1. We investigate the impacts for four cases based on various combinations of mean and variability changes in temperature with climate change. The results demonstrate that higher mortality is attributed to increases in the mean and variability of temperature with climate change rather than with the change in mean temperature alone. This has implications for interpreting existing impacts estimates that have used the delta method. We present a novel method for the creation of temperature projection time series that includes changes in the mean and variability of temperature with climate change and is not influenced by climate model bias in the modelled present. The method should be useful for future impacts assessments. Few studies consider the implications that the limitations of the climate model may have on the heatrelated mortality impacts. Here, we demonstrate the importance of considering this by conducting an evaluation of the daily and extreme temperatures from HadCM3, which demonstrates that the estimates of future heat-related mortality for Dallas and Lisbon may be overestimated due to positive climate model bias. Likewise, estimates for Boston and London may be underestimated due to negative climate model bias. Finally, we briefly consider uncertainties in the impacts associated with greenhouse gas emissions and acclimatisation. The uncertainties in the mortality impacts due to different emissions scenarios of greenhouse gases in the future varied considerably by location. Allowing for acclimatisation to an extra 2°C in mean temperatures reduced future heat-related mortality by approximately half that of no acclimatisation in each city.

Using the Met Office large-eddy model (LEM) we simulate a mixed-phase altocumulus cloud that was observed from Chilbolton in southern England by a 94 GHz Doppler radar, a 905 nm lidar, a dual-wavelength microwave radiometer and also by four radiosondes. It is important to test and evaluate such simulations with observations, since there are significant differences between results from different cloud-resolving models for ice clouds. Simulating the Doppler radar and lidar data within the LEM allows us to compare observed and modelled quantities directly, and allows us to explore the relationships between observed and unobserved variables. For general-circulation models, which currently tend to give poor representations of mixed-phase clouds, the case shows the importance of using: (i) separate prognostic ice and liquid water, (ii) a vertical resolution that captures the thin layers of liquid water, and (iii) an accurate representation the subgrid vertical velocities that allow liquid water to form. It is shown that large-scale ascents and descents are significant for this case, and so the horizontally averaged LEM profiles are relaxed towards observed profiles to account for these. The LEM simulation then gives a reasonable. cloud, with an ice-water path approximately two thirds of that observed, with liquid water at the cloud top, as observed. However, the liquid-water cells that form in the updraughts at cloud top in the LEM have liquid-water paths (LWPs) up to half those observed, and there are too few cells, giving a mean LWP five to ten times smaller than observed. In reality, ice nucleation and fallout may deplete ice-nuclei concentrations at the cloud top, allowing more liquid water to form there, but this process is not represented in the model. Decreasing the heterogeneous nucleation rate in the LEM increased the LWP, which supports this hypothesis. The LEM captures the increase in the standard deviation in Doppler velocities (and so vertical winds) with height, but values are 1.5 to 4 times smaller than observed (although values are larger in an unforced model run, this only increases the modelled LWP by a factor of approximately two). The LEM data show that, for values larger than approximately 12 cm s(-1), the standard deviation in Doppler velocities provides an almost unbiased estimate of the standard deviation in vertical winds, but provides an overestimate for smaller values. Time-smoothing the observed Doppler velocities and modelled mass-squared-weighted fallspeeds shows that observed fallspeeds are approximately two-thirds of the modelled values. Decreasing the modelled fallspeeds to those observed increases the modelled IWC, giving an IWP 1.6 times that observed.

[ 1] A rapid increase in the variety, quality, and quantity of observations in polar regions is leading to a significant improvement in the understanding of sea ice dynamic and thermodynamic processes and their representation in global climate models. We assess the simulation of sea ice in the new Hadley Centre Global Environmental Model (HadGEM1) against the latest available observations. The HadGEM1 sea ice component uses elastic-viscous-plastic dynamics, multiple ice thickness categories, and zero-layer thermodynamics. The model evaluation is focused on the mean state of the key variables of ice concentration, thickness, velocity, and albedo. The model shows good agreement with observational data sets. The variability of the ice forced by the North Atlantic Oscillation is also found to agree with observations.
