La construcción del aprendizaje cultural: Análisis de las percepciones del profesorado de inglés

Today teaching and learning tend to be viewed in a constructivist and/or (social) constructivist perspective. Learning is regarded as a process of meaning construction in which the individual actively participates in interaction with the learning environment. From a constructivist perspective, culture learning is considered as an active process which allows the students the transformation of knowledge. The teacher’s role as mediator in this process requires the development of abilities to scaffold learning and guide learners towards autonomy and independent culture learning. In this paper we report a research project which investigated to what extent Spanish EFL teachers depart from their learners current level of familiarity with the target culture and to what extent teachers current approaches to the teaching of culture in secondary education can be characterised as constructivist. The results show that the foreign culture teaching approach adopted by these teachers can only in part be characterised as scaffolding the learning process towards learner autonomy

Vulnerability of Spanish forests under climatic change: evaluation through models

Los bosques son ecosistemas fundamentales en la generación de servicios ecosistémicos y, por tanto, para el bienestar humano. El cambio global (incluyendo cambio climático y cambios en el uso del suelo) puede, sin embargo, alterar la dinámica y el funcionamiento de los ecosistemas, afectando al futuro suministro de servicios ecosistémicos. La vulnerabilidad frente al cambio global depende de la exposición (magnitud del cambio), la sensibilidad (susceptibilidad al cambio), y la capacidad de adaptación (habilidad para ajustarse al cambio) de las especies. En el presente trabajo presentamos diversas aproximaciones de modelización que permiten analizar los diferentes componentes de la vulnerabilidad, e incluimos ejemplos desarrollados para bosques de la península Ibérica. A pesar de estos avances, la evidencia empírica y teórica para integrar los impactos potenciales (i.e. incluyendo la exposición y la sensibilidad) y la capacidad de adaptación de las especies, es escasa. Por ello, para una adecuada evaluación sería necesario mejorar el conocimiento existente sobre la sensibilidad y capacidad de adaptación de las especies y su respuesta frente a cambios ambientales extremos (por ejemplo, mediante redes de seguimiento a largo plazo), integrando adecuadamente la información obtenida en modelos que incluyan procesos basados en diferentes niveles de organización biológica, desde procesos fisiológicos a modelos agregados de distribución de especies.Forest ecosystems contribute to human well-being providing critical ecosystem services. Global change (including climate and land-use changes), however, can alter ecosystem functioning and structure, even jeopardizing the future supply of ecosystem services. Vulnerability to global change depends on exposition (magnitude of the change), sensitivity (susceptibility to the change), and adaptive capacity (ability to adjust to the change) of the species. Here, we summarize diverse modeling approaches to analyze the different components of vulnerability, providing specific examples focused on Iberian forests. Despite of these advances, our empirical and theoretical ability to provide integrated assessments of potential impacts (i.e. including both exposition and sensitivity) of climate change and adaptive capacity is still very limited. An adequate estimation of vulnerability requires improving our knowledge about the adaptive capacity of species and their response to extreme environmental changes (e.g. through long-term monitoring networks), as well as integrating the knowledge obtained from models developed at different levels of biological organization, from physiological process-based models to aggregated species distribution models.Esta revisión ha sido financiada por el proyecto REMEDINAL-2 de la Comunidad de Madrid (S2009/AMB-1783) y el proyecto IN-2013-004 de The Leverhulme Trust

Predictive Composition of Pictogram Messages for Users with Autism.

Communication is a basic need for every person. However, there are many people who present disabilities that prevent communication through natural language. Augmentative and alternative communication (AAC) systems, including those based on pictograms, attempt to facilitate the communication for people with this kind of difficulties. In this paper we present PictoEditor, an augmentative and alternative communication application for the composition of pictogram messages for users with autism that incorporates prediction functionalities. Although such functionalities have been widely studied in text-based augmentative and alternative communication tools, they have not been applied to pictogram based ones. The results show that prediction based on frequency of use of specific pictograms improves the immediate availability of the desired pictograms, but the improvement with prediction based on sequencing of pseudo-syntactic types of pictogram is not as clear.pre-print4500 K

Population dynamics of a fragmented subtidal Zostera marina population affected by shell fishing

This investigation illustrates the spatial and temporal dynamics of a Zostera marina seagrass meadow affected by clam harvesting. Photointerpretation of satellite imagery corresponding to years 2007, 2013, 2017 and 2018, combined with field monitoring in 2019 allowed assessing the spatial coverage, population dynamics and genetic characterization of the Z. marina population in areas impacted and non-impacted by the shellfishing activity. The impacted meadow displayed a highly fragmented and discontinuous seagrass matrix anthropogenically induced by the periodical disturbance associated with bottom raking. A continuous colonization process characterized the seagrass landscape, where the area occupied by the meadow varied by a two-fold factor, with changes even exceeding 86% in some years. Only 740 m2 (ca. 15%) of the seagrass matrix remained vegetated in the four years monitored in this investigation. The number of patches showed a large interannual variability, exceeding 100% in the four years studied, ranging from 58 to 199, while the border effect perimeter/area indicator showed a two-fold variation ranging between 1 and 2. Clearly differentiated patterns were observed in shoot density, biomass, and flowering density between shellfishing-induced patches of different sizes and the long-term non-impacted areas. A significant pattern of genetic differentiation among impacted and control populations were also found. Our results showed that population dynamics varied as a function of Z. marina patch-sizes, thus reinforcing the need for a combined approach involving seascape structure and patch dynamics with population dynamics and genetic structure to assess the impact of disturbances on seagrass ecosystems

A comparison of the prediction of apparent metabolisable energy content of starchy grains and cereal by-products for poultry from its chemical components, in vitro analysis or near-infrared reflectance spectroscopy

Regression models including chemical composition, in vitro digestibility and near infrared reflectance spectroscopy (NIRS) were compared in order to predict the energy value of several feed ingredients for poultry. The nitrogen-corrected apparent metabolisable energy content (AMEn) in cockerels and its proportion on total gross energy (AMEn/GE) were determined in 94 batches from six starchy grains and six cereal byproducts. Two preliminary trials were also designed to adapt in vitro methods for prediction of in vivo energy values for poultry. Mean concentrations of AMEn of the ingredient studied ranged from 2,464 to 3,595 kcal kg -1 DM, and those of AMEn/GE from 53.7 to 80.0%. The most precise model of prediction of AMEn and AMEn/GE values was that based on NIRS equations (R2 cv = 0.823 and 0.861, respectively). The best single chemical predictor of these energy values was the neutral detergent fibre concentration (R2 = 0.616 and 0.736, respectively). Further inclusion of ether extract and ash contents in the AMEn model and those of starch and ether extract in the AMEn/GE model allowed increasing coefficients of determination up to 0.791 and 0.839, respectively. A model including linear and quadratic effects of in vitro organic matter digestibility (IVOMd) provided a similar prediction of AMEn/GE values (R2 = 0.833). However the prediction of AMEn from IVOMd was worse (R2 = 0.62), as variations among batches of GE concentration (from 4,225 to 5,896 kcal kg –1 DM) were little related to in vitro digestibility values

Exploring the Potential of Concept Associations for the Creative Generation of Linguistic Artifacts: A Case Study With Riddles and Rhetorical Figures

Automatic generation of linguistic artifacts is a problem that has been sporadically tackled over the years. The main goal of this paper is to explore how concept associations can be useful from a computational creativity point of view to generate some of these artifacts. We present an approach where finding associations between concepts that would not usually be considered as related (for example life and politics or diamond and concrete) could be the seed for the generation of creative and surprising linguistic artifacts such as rhetorical figures (life is like politics) and riddles (what is as hard as concrete?). Human volunteers evaluated the quality and appropriateness of the generated figures and riddles, and the results show that the concept associations obtained are useful for producing these kinds of creative artifacts

Gravedad del síndrome de apnea-hipopnea obstructiva del sueño, raza, edad y patrón de crecimiento como indicadores de complicaciones respiratorias tras adenoamigdalectomía, en paciente pediátrico

In wide range of pediatric obstructive sleep apnea hypopnea síndrome (OSAHS), tonsillectomy with adenoidectomy is the main treatment strategy. OSAHS severity evaluation, age and growth pattern are crucial to plan a day case surgery. The aim of this review is risk respiratory factors analysis of adenotonsillectomy (AA) perioperative period. Severe OSAHS increases the incidence of adverse events, and polysomnography is the test of choice for its evaluation. However, it does not seem clearly associated with major complications or bleeding, so the experience of the equipment and the available resources can make a day case surgery possible. En la mayor parte de los casos de SAHOS pediátrico, el tratamiento de elección, es la amigdalectomía con adenoidectomía. En la consulta preanestésica, la evaluación de la gravedad del SAHOS, edad, crecimiento y raza pueden ser relevantes si se quiere optar por un circuito ambulatorio. El objetivo de este artículo, es la revisión de los factores de riesgo para sufrir complicaciones respiratorias, en el perioperatorio de amigdalectomía y adenoamigdalectomía. El SAHOS grave aumenta la incidencia de eventos adversos, siendo la polisomnografía es la prueba de elección para su evaluación. Sin embargo, no parece claramente asociada con complicaciones mayores o sangrado, por lo que la experiencia del equipo y los recursos disponibles, pueden hacer posible una CMA para AA.
