Viewpoint-Based Ambient Occlusion

We've developed a new ambient occlusion technique based on an information-theoretic framework. Essentially, our method computes a weighted visibility from each object polygon to all viewpoints; we then use these visibility values to obtain the information associated with each polygon. So, just as a viewpoint has information about the model's polygons, the polygons gather information on the viewpoints. We therefore have two measures associated with an information channel defined by the set of viewpoints as input and the object's polygons as output, or vice versa. From this polygonal information, we obtain an occlusion map that serves as a classic ambient occlusion technique. Our approach also offers additional applications, including an importance-based viewpoint-selection guide, and a means of enhancing object features and producing nonphotorealistic object visualizations

Informational Aesthetics Measures

The Birkhoff aesthetic measure of an object is the ratio between order and complexity. Informational aesthetics describes the interpretation of this measure from an information-theoretic perspective. From these ideas, the authors define a set of ratios based on information theory and Kolmogorov complexity that can help to quantify the aesthetic experience

Hiperactividade e estratégias de intervenção : aplicação de estratégias de intervenção por docentes do 1º CEB

O presente trabalho, aborda o tema da Hiperactividade, uma temática cada vez mais actual e que no dia a dia vem preocupando toda a comunidade educativa. Diagnóstico precoce e tratamento adequado podem reduzir drasticamente os problemas escolares do aluno hiperactivo. A nível educativo existe todo um conjunto de estratégias e modificações que se podem aplicar no ambiente de aprendizagem e nos métodos de trabalho do docente, com vista a melhorar o desempenho escolar dos alunos hiperactivos. Assim, é importante estabelecer estratégias que permitam, mais facilmente, ajustar o comportamento da criança, de tal modo que esta aprenda e deixe que os outros alunos, da turma onde se encontra integrada, aprendam também. Fundamentamo-nos numa bibliografia variada de diversos autores, que ao longo dos anos se vêm preocupando com este problema da hiperactividade. Numa segunda parte, foi realizado um questionário de modo a apurar quais as estratégias de intervenção educativa que os docentes do 1ºCEB consideram mais adequadas utilizar com alunos hiperactivos. Espera-se contribuir para o conhecimento da representação do tema e da prática docente.

La protección constitucional de la familia (Artículos Varios)

La autora enfatiza la necesidad de dotar de ductilidad al Derecho frente a los cambios sociales, refiriéndose particularmente a la familia y sus transformaciones como institución jurídica y como construcción social y cultural. Reflexiona sobre el carácter hegemónico de la familia nuclear burguesa en el derecho, planteando el desafío de que éste responda a la realidad social que muestra diversas formas de familia que no calzan en el modelo dominante. Analiza al matrimonio como el paradigma de la relación de pareja, incluso en la aspiración de aquellos que quieren dotar a su unión de efectos jurídicos, como es el caso de las parejas de homosexuales que se quieren vincular en los mismos términos, o las uniones de hecho, sean éstas heterosexuales u homosexuales, demostrando que, el reconocimiento de otros modelos de familia y la respuesta que se dé a estas demandas, pueden alterar la posición que el matrimonio tiene en la Constitución, y en la garantía institucional que en la misma se consagra.

El discurso romántico-masculino sobre la virtud femenina: ventriloquismo travesti, censura literaria y violencia donjuanesca en Montalvo y Mera (Estudios)

El autor revisa el discurso de Juan Montalvo en dos textos de Las Catilinarias y en El Regenerador, señalando las estrategias que emplea para apoyar el control patriarcal sobre la mujer: simula una voz femenina que habla por y para las mujeres, sobre sus propias necesidades y deseos, censura y restringe la creatividad poética femenina, y sanciona a aquellas mujeres rebeldes que cuestionan la autoridad masculina. Señala el autor que, sobre la educación de la mujer, el “liberalismo católico” de Montalvo resulta similar a la ideología conservadora y católica de su enemigo político, el presidente García Moreno. De igual forma, en Ojeada histórico-crítica de la poesía ecuatoriana, Juan León Mera censura la autoría, autoridad y autorización para escribir de dos poetas ecuatorianas (Dolores Veintimilla y Mercedes González de Moscoso), como formas de controlar y vigilar esas mismas subjetividades femeninas “manipulables, impulsivas o pecaminosas”, hace algo similar respecto de la obra de Sor Juana, en Obras selectas de la célebre monja de Méjico Sor Juana Inés de la Cruz. Por último, en su Geometría moral, Juan Montalvo da un paso más allá, y revela el lado egocéntrico y perverso de la autoridad masculina.

A review of the theoretical basis for bulk mass flux convective parameterization

Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining-detraining plume. We review the underpinning mathematical model for such parameterizations, in particular by comparing it with spectral models in which elements are not combined into the representative plume. The chief merit of a bulk model is that the representative plume can be described by an equation set with the same structure as that which describes each element in a spectral model. The equivalence relies on an ansatz for detrained condensate introduced by Yanai et al. (1973) and on a simplified microphysics. There are also conceptual differences in the closure of bulk and spectral parameterizations. In particular, we show that the convective quasi-equilibrium closure of Arakawa and Schubert (1974) for spectral parameterizations cannot be carried over to a bulk parameterization in a straightforward way. Quasi-equilibrium of the cloud work function assumes a timescale separation between a slow forcing process and a rapid convective response. But, for the natural bulk analogue to the cloud-work function (the dilute CAPE), the relevant forcing is characterised by a different timescale, and so its quasi-equilibrium entails a different physical constraint. Closures of bulk parameterization that use the non-entraining parcel value of CAPE do not suffer from this timescale issue. However, the Yanai et al. (1973) ansatz must be invoked as a necessary ingredient of those closures.

A comparison of diatom phosphorus transfer functions and export coefficient models as tools for reconstructing lake nutrient histories

1. We compared the baseline phosphorus (P) concentrations inferred by diatom-P transfer functions and export coefficient models at 62 lakes in Great Britain to assess whether the techniques produce similar estimates of historical nutrient status. 2. There was a strong linear relationship between the two sets of values over the whole total P (TP) gradient (2-200 mu g TP L-1). However, a systematic bias was observed with the diatom model producing the higher values in 46 lakes (of which values differed by more than 10 mu g TP L-1 in 21). The export coefficient model gave the higher values in 10 lakes (of which the values differed by more than 10 mu g TP L-1 in only 4). 3. The difference between baseline and present-day TP concentrations was calculated to compare the extent of eutrophication inferred by the two sets of model output. There was generally poor agreement between the amounts of change estimated by the two approaches. The discrepancy in both the baseline values and the degree of change inferred by the models was greatest in the shallow and more productive sites. 4. Both approaches were applied to two lakes in the English Lake District where long-term P data exist, to assess how well the models track measured P concentrations since approximately 1850. There was good agreement between the pre-enrichment TP concentrations generated by the models. The diatom model paralleled the steeper rise in maximum soluble reactive P (SRP) more closely than the gradual increase in annual mean TP in both lakes. The export coefficient model produced a closer fit to observed annual mean TP concentrations for both sites, tracking the changes in total external nutrient loading. 5. A combined approach is recommended, with the diatom model employed to reflect the nature and timing of the in-lake response to changes in nutrient loading, and the export coefficient model used to establish the origins and extent of changes in the external load and to assess potential reduction in loading under different management scenarios. 6. However, caution must be exercised when applying these models to shallow lakes where the export coefficient model TP estimate will not include internal P loading from lake sediments and where the diatom TP inferences may over-estimate TP concentrations because of the high abundance of benthic taxa, many of which are poor indicators of trophic state.
