La Revoluci??n Francesa y su influencia en la educaci??n espa??ola

Se analiza el contenido de las conferencias y comunicaciones presentadas por hispanistas franceses e historiadores de la educaci??n espa??ola al Coloquio Internacional que, sobre 'Las influencias de la Revoluci??n Francesa en la educaci??n en Espa??a', se ha celebrado en 1989, para conmemorar el Bicentenario de la Revoluci??n Francesa. Las tres conferencias abordan los siguientes temas: el pensamiento de Condorcet, considerado el primer te??rico de la escuela republicana y una de las fuentes de inspiraci??n del liberalismo espa??ol en materia de pol??tica educativa; la complejidad de las relaciones entre educaci??n y Revoluci??n y la repercusi??n de la Revoluci??n Francesa en el origen de un nuevo sistema educativo espa??ol. Respecto al contenido de las veintitr??s comunicaciones, se estudian las formas e intensidades que adquiri?? el influjo revolucionario franc??s en la educaci??n europea y, en concreto, en la educaci??n espa??ola a trav??s del an??lisis del pensamiento educativo de ilustrados, afrancesados y liberales y en la indagaci??n de esta influencia en la pol??tica y la pr??ctica educativas en Espa??a. Otras comunicaciones abordan el tema desde la perspectiva de historia local y desde el estudio de v??as informales de educaci??n, como sermonarios y catecismos.

La liga contra la ignorancia : burgues??a y educaci??n en la Valencia de 1880

Se explica la creaci??n, expansi??n y objetivos y actividades de la Liga contra la Ignorancia. Se inaugura de forma oficial en julio de 1880 culminando un proceso de meses. Ciudades importantes como Madrid o Barcelona siguieron el ejemplo de la creada en Valencia. Los estatutos de la Liga recog??an expresamente su objetivo: fomento de la instrucci??n, educaci??n y moralizaci??n de las clases populares, sobre todo en la primera ense??anza. El trabajo de la Liga qued??, en gran medida, ce??ido al terreno ideol??gico con dos puntos referenciales clave: la ense??anza popular y la moralidad en las clases obreras.

Utilización de las TICs en la enseñanza de las ciencias

La enseñanza integrada de la ciencia con la tecnología aunque es tema que los últimos años ha cobrado gran importancia ha sido defendida desde hace muchos años atrás (por ejemplo, fue propugnada por la Division of Science, Technical and Environmental Education de la UNESCO) y a partir de la segunda mitad del siglo XX, ésta relación se ha intensificando mucho mas, pero si bien es cierto que la técnica ha existido sin ciencia, ésta siempre ha incluido elementos tecnol��gicos que podrían incorporarse a la educación científica ayudando a cambiar la visión de ciencia que se enseña tradicionalmente y que, generalmente, ignora o distorsiona el papel de la tecnología en el desarrollo científico y sus relaciones con la ciencia y la sociedad

Contagem de células conjuntivais por citologia de impressão em bovinos e equinos

A citologia por impressão é um método não invasivo útil para avaliar a superfície ocular. Consiste na aplicação de um fragmento de papel filtro sobre a conjuntiva. As amostras obtidas podem ter até três camadas de células e são distendidas em l��minas histol��gicas. O estudo teve como objetivo avaliar o padrão qualitativo e quantitativo das células da conjuntiva bulbar em bovinos e cavalos clinicamente saudáveis para facilitar o diagnóstico de doenças oculares externas. Para este fim, foram coletadas amostras de células externas da conjuntiva ocular pelo método de citologia de impressão de 15 bovinos e 15 equinos adultos. Para o exame citol��gico as amostras foram coradas por Giemsa e Shorr. Duas l��minas foram preparadas de cada animal, uma do olho esquerdo e outro do olho direito e foram contadas 800 células em total. Para a análise estatística, o ANOVA foi utilizado, foram considerados significativos os valores de p < 0,05. A análise permitiu estabelecer diferenças no numero de células caliciformes, linfócitos e eritrócitos entre espécies e animais. A citologia por impressão da conjuntiva bulbar foi eficaz na análise celular e foi bem aceita pelos bovinos e equinos.

Controlling nitrate pollution: an integrated approach

The introduction of the EU Water Framework Directive requires policy to address non-point source pollution as part of an overall integrated strategy to improve the ecological status of water bodies. In this paper, we combine an economic optimisation framework with a dynamic simulation model of N transport in the Kennet Catchment to link decisions taken at the farm level to reductions in nitrate concentrations in the River Kennet. We examine a variety of policies targeted at reducing fertiliser use and changing the way in which farm land is used. We find that a tax on nitrogen emerges as the best policy both in terms of cost- and environmental effectiveness. Such a policy involves a considerable reduction in fertiliser use, as well as, a restructuring of land-use away from arable towards increased use of set-aside. Budgetary implications of such a radical move towards set-aside would be huge and hence unlikely to be politically palatable given the objective of reducing the EU budgetary allocation to agriculture. Additionally, the current rise in world demand for food may also mitigate calls for increasing the proportion of land taken out of agricultural production. Although the study succeeds in establishing a link between actions on the farm and nitrate concentrations in the stream water, further work is required to explore the effect of the retention of nitrates in the unsaturated zone and groundwater on this link.

Does the North Atlantic Oscillation show unusual persistence on intraseasonal timescales?

Previous studies have argued that the autocorrelation of the winter North Atlantic Oscillation (NAO) index provides evidence of unusually persistent intraseasonal dynamics. We demonstrate that the autocorrelation on intraseasonal time-scales of 10–30 days is sensitive to the presence of interannual variability, part of which arises from the sampling of intraseasonal variability and the remainder of which we consider to be “externally forced”. Modelling the intraseasonal variability of the NAO as a red noise process we estimate, for winter, ~70% of the interannual variability is externally forced, whereas for summer sampling accounts for almost all of the interannual variability. Correcting for the externally forced interannual variability has a major impact on the autocorrelation function for winter. When externally forced interannual variability is taken into account the intrinsic persistence of the NAO is very similar in summer and winter (~5 days). This finding has implications for understanding the dynamics of the NAO.

Methods and resources for climate impacts research: achieving synergy

The prediction of climate variability and change requires the use of a range of simulation models. Multiple climate model simulations are needed to sample the inherent uncertainties in seasonal to centennial prediction. Because climate models are computationally expensive, there is a tradeoff between complexity, spatial resolution, simulation length, and ensemble size. The methods used to assess climate impacts are examined in the context of this trade-off. An emphasis on complexity allows simulation of coupled mechanisms, such as the carbon cycle and feedbacks between agricultural land management and climate. In addition to improving skill, greater spatial resolution increases relevance to regional planning. Greater ensemble size improves the sampling of probabilities. Research from major international projects is used to show the importance of synergistic research efforts. The primary climate impact examined is crop yield, although many of the issues discussed are relevant to hydrology and health modeling. Methods used to bridge the scale gap between climate and crop models are reviewed. Recent advances include large-area crop modeling, quantification of uncertainty in crop yield, and fully integrated crop–climate modeling. The implications of trends in computer power, including supercomputers, are also discussed.

Impact of Resolution on the Tropical Pacific Circulation in a Matrix of Coupled Models

Results are presented from a matrix of coupled model integrations, using atmosphere resolutions of 135 and 90 km, and ocean resolutions of 1° and 1/3°, to study the impact of resolution on simulated climate. The mean state of the tropical Pacific is found to be improved in the models with a higher ocean resolution. Such an improved mean state arises from the development of tropical instability waves, which are poorly resolved at low resolution; these waves reduce the equatorial cold tongue bias. The improved ocean state also allows for a better simulation of the atmospheric Walker circulation. Several sensitivity studies have been performed to further understand the processes involved in the different component models. Significantly decreasing the horizontal momentum dissipation in the coupled model with the lower-resolution ocean has benefits for the mean tropical Pacific climate, but decreases model stability. Increasing the momentum dissipation in the coupled model with the higher-resolution ocean degrades the simulation toward that of the lower-resolution ocean. These results suggest that enhanced ocean model resolution can have important benefits for the climatology of both the atmosphere and ocean components of the coupled model, and that some of these benefits may be achievable at lower ocean resolution, if the model formulation allows.

U.K. HiGEM: The New U.K. High-Resolution Global Environment Model���Model Description and Basic Evaluation

This article describes the development and evaluation of the U.K.’s new High-Resolution Global Environmental Model (HiGEM), which is based on the latest climate configuration of the Met Office Unified Model, known as the Hadley Centre Global Environmental Model, version 1 (HadGEM1). In HiGEM, the horizontal resolution has been increased to 0.83° latitude × 1.25° longitude for the atmosphere, and 1/3° × 1/3° globally for the ocean. Multidecadal integrations of HiGEM, and the lower-resolution HadGEM, are used to explore the impact of resolution on the fidelity of climate simulations. Generally, SST errors are reduced in HiGEM. Cold SST errors associated with the path of the North Atlantic drift improve, and warm SST errors are reduced in upwelling stratocumulus regions where the simulation of low-level cloud is better at higher resolution. The ocean model in HiGEM allows ocean eddies to be partially resolved, which dramatically improves the representation of sea surface height variability. In the Southern Ocean, most of the heat transports in HiGEM is achieved by resolved eddy motions, which replaces the parameterized eddy heat transport in the lower-resolution model. HiGEM is also able to more realistically simulate small-scale features in the wind stress curl around islands and oceanic SST fronts, which may have implications for oceanic upwelling and ocean biology. Higher resolution in both the atmosphere and the ocean allows coupling to occur on small spatial scales. In particular, the small-scale interaction recently seen in satellite imagery between the atmosphere and tropical instability waves in the tropical Pacific Ocean is realistically captured in HiGEM. Tropical instability waves play a role in improving the simulation of the mean state of the tropical Pacific, which has important implications for climate variability. In particular, all aspects of the simulation of ENSO (spatial patterns, the time scales at which ENSO occurs, and global teleconnections) are much improved in HiGEM.
