    What Have We Learned After One Year of Remote Teaching and Learning? A Critical Conversation between Two Language Educators

    Get PDF
    In this critical conversation, two language educators reflect on their experiences of online instruction after nearly two years of teaching during the Covid 19 pandemic. The duoethnographers share the challenges they faced to adapt their teaching and assessment for remote delivery, as well as how their pedagogical orientations transformed to engage with learners online. The discussion focuses on teaching both synchronously and asynchronously, re-thinking language assessment, and the authors’ strategies to manage a sustainable and healthy workflow. This last aspect is of significant importance given how much these two educators had to learn to teach in ways and through media they had not been trained for. By unpacking their efforts to respond to their learners’ needs, the authors propose capitalizing on these challenges as valuable professional development opportunities and invite other language teachers to share their experiences

    Patient dossier: healthcare queries over distributed resources

    As with many other aspects of the modern world, in healthcare, the explosion of data and resources opens new opportunities for the development of added-value services. Still, a number of specific conditions on this domain greatly hinders these developments, including ethical and legal issues, fragmentation of the relevant data in different locations, and a level of (meta)data complexity that requires great expertise across technical, clinical, and biological domains. We propose the Patient Dossier paradigm as a way to organize new innovative healthcare services that sorts the current limitations. The Patient Dossier conceptual framework identifies the different issues and suggests how they can be tackled in a safe, efficient, and responsible way while opening options for independent development for different players in the healthcare sector. An initial implementation of the Patient Dossier concepts in the Rbbt framework is available as open-source at https://github.com/mikisvaz and https://github.com/Rbbt-Workflows.This work has received funding from the Elixir-Excelerate project, from the European Union's Horizon 2020 Research and Innovation Programme, under grant agreement N. 676559, and from Plataforma de Recursos Biomoleculares y Bioinformáticos PT13/0001/0030. Additional support came from the Lenovo - BSC Master Collaboration Agreement (2015) and from the IBM-BSC Deep Learning Centre (2016).

    Complex networks: new trends for the analysis of brain connectivity

    Full text link
    Today, the human brain can be studied as a whole. Electroencephalography, magnetoencephalography, or functional magnetic resonance imaging techniques provide functional connectivity patterns between different brain areas, and during different pathological and cognitive neuro-dynamical states. In this Tutorial we review novel complex networks approaches to unveil how brain networks can efficiently manage local processing and global integration for the transfer of information, while being at the same time capable of adapting to satisfy changing neural demands.Comment: Tutorial paper to appear in the Int.

    Regulación en mercados energéticos: caso energía eólica (1990-2009)

    Get PDF
    El “boom” de las energías alternativas, se desencadenó según la Comisión Europea (2012), a partir de los años 70, cuando la crisis del petróleo entregó de forma implícita un mensaje a todo el mundo sobre agotamiento de recursos, obligando a emprender la búsqueda de nuevas fuentes de energía. Luego, en los años 80 toma fuerza la iniciativa de desarrollo sostenible cuyo objetivo principal es minimizar el uso de los combustibles fósiles, reducción necesaria al comprender que el consumo excesivo de países desarrollados, originando el problema de calentamiento global, acompañado por consecuencias en la salud de grandes poblaciones. El Protocolo de Kioto, definido bajo la legislación de la Unión Europea, nace como “instrumento jurídico de carácter internacional que busca la lucha contra el cambio climático; por medio de compromisos de países industrializados para reducir sus niveles de emisiones de gases de efecto invernadero” (European Union , 2012).31 p.Contenido parcial: La variabilidad en el tiempo y en el espacio de las dinámicas económicas -- Categorías conceptuales e ideas centrales de la teoría de la regulación francesa -- Ejes temáticos: crisis económicas y la unidad histórica estado-mercado -- Reseña de trabajos aplicativos elaborados bajo el enfoque regulacionista

    Preparation of Continuous Highly Hydrophobic Pure Silica ITQ-29 Zeolite Layers on Alumina Supports

    Full text link
    [EN] The preparation of continuous layers of highly hydrophobic pure silica ITQ-29 zeolite, potentially applicable as hydrophobic membranes for separation of molecules based on their polarity, has been investigated. Continuous layers of intergrown ITQ-29 zeolite crystals were successfully grown on porous alumina supports by optimization of the synthesis conditions, such as the appropriate selection of the seeds, the procedure for the gel preparation, and the calcination conditions. This resulted in the formation of all silica ITQ-29 zeolite layers without the presence of germanium required in previously reported ITQ-29 membranes, with the subsequent improvement in quality and stability, as verified by the absence of cracks after calcination. We have proved that the incorporation of aluminum from the support into the zeolite layer does not occur, neither during the secondary growth nor through migration of aluminum species during calcination.This research was funded by the European Research Council, grant ERC-AdG-2014-671093 (SynCatMatch) and the Spanish Government, through "Severo Ochoa" grant SEV-2016-0683 and RTI2018-101784-B-I00.Palomino Roca, M.; Ono, H.; Valencia Valencia, S.; Corma Canós, A.
