    Second language learning: finding ways to integrate ICT resources and right strategies for language learning, translation and interpreting Second language learning has gained importance as language accreditations have become imperative for any profession or academic career. Undergraduate students in Philology, Translation Studies, Tourism Studies or the like follow language accreditation programmes in order to be able to compile a valid and solid CV when they complete their degrees, master or PhD programmes. In the case of Translation students, they are subjects with strong motivation for language learning applied to translation or interpreting tasks. Language technologies and tools constitute an essential part of their learning processes and language teachers should find a way of optimising the use of these resources. For this purpose, we have conducted a survey among students, trying to find out which web resources they use, how they use them (or not) and why. Using these data, we considered new strategies to help students get the most out of these tools; in particular, we analysed the pros and cons of machine translation tools, such as deepL and Google Translator, as well as corpus linguistics tools.Universidad de Málaga.

    Use of Taguchi Design of Experiments to Determine ALPLS Ascent Delta-5 Sensitivities and Total Mass Sensitivities to Release Conditions and Vehicle Parameters

    Get PDF
    The objective of this study is to evaluate the use of Taguchi's Design of Experiment Methods to improve the effectiveness of this and future parametric studies. Taguchi Methods will be applied in addition to the typical approach to provide a mechanism for comparing the results and the cost or effort necessary to complete the studies. It is anticipated that results of this study should include an improved systematic analysis process, an increase in information obtained at a lower cost, and a more robust, cost effective vehicle design

    The politics of learning within Post-Yerevan EHEA: Some epistemological remarks on the role of university lecturers

    Get PDF
    XXI Jornades de Foment de la Investigació de la Facultat de Ciències Humanes i Socials (Any 2016)The last 20 years have witnessed a gradual and constant shift in the way society and transnational education institutions, namely the European Higher Education Area (EHEA), conceptualise and address the education/learning activity. That shift in the dominant education paradigm, epistemologically rooted, affects among other stances the role of lecturers, displacing the teaching figure from the centre towards the periphery of the education process. The student-centred narratives in education have a direct impact on lecturers, their self-concept, and the expectations regarding their class contents and methodology. The following paper addresses that concern, advocating for a reconceptualisation of the role of lecturers under the current studentcentred epistemological approach

    On the conformal gauge of a compact metric space

    Get PDF
    In this article we study the Ahlfors regular conformal gauge of a compact metric space (X,d)(X,d), and its conformal dimension dimAR(X,d)\mathrm{dim}_{AR}(X,d). Using a sequence of finite coverings of (X,d)(X,d), we construct distances in its Ahlfors regular conformal gauge of controlled Hausdorff dimension. We obtain in this way a combinatorial description, up to bi-Lipschitz homeomorphisms, of all the metrics in the gauge. We show how to compute dimAR(X,d)\mathrm{dim}_{AR}(X,d) using the critical exponent QNQ_N associated to the combinatorial modulus.Comment: 49 pages, 9 figure

    Molybdenum-catalyzed enantioselective sulfoxidation controlled by a nonclassical hydrogen bond between coordinated chiral imidazolium-based dicarboxylate and peroxido ligands

    Chiral alkyl aryl sulfoxides were obtained by molybdenum-catalyzed oxidation of alkyl aryl sulfides with hydrogen peroxide as oxidant in mild conditions with high yields and moderate enantioselectivities. The asymmetry is generated by the use of imidazolium-based dicarboxylic compounds, HLR. The in-situ-generated catalyst, a mixture of aqueous [Mo(O)(O2)2(H2O)n] with HLR as chirality inductors, in the presence of [PPh4]Br, was identified as the anionic binuclear complex [PPh4]{[Mo(O)(O2)2(H2O)]2( -LR)}, according to spectroscopic data and Density Functional Theory (DFT) calculations. A nonclassical hydrogen bond between one C–H bond of the alkyl R group of coordinated (LR)- and one oxygen atom of the peroxido ligand was identified as the interaction responsible for the asymmetry in the process. Additionally, the step that governs the enantioselectivity was theoretically analyzed by locating the transition states of the oxido-transfer to PhMeS of model complexes [Mo(O)(O2)2(H2O)( 1-O-LR)]- (R = H, iPr). The DDG6= is ca. 0 kcal mol-1 for R = H, racemic sulfoxide, meanwhile for chiral species the DDG6= of ca. 2 kcal mol-1 favors the formation of (R)-sulfoxide.Junta de Andalucía (Proyecto de Excelencia FQM-7079)Universidad de Sevilla (VI Plan Propio

    Halpha surface photometry of galaxies in the Virgo cluster. IV: the current star formation in nearby clusters of galaxies

    Get PDF
    Halpha+[NII] imaging observations of 369 late-type galaxies in the Virgo cluster and in the Coma/A1367 supercluster are analyzed. They constitute an optically selected sample (m_p<16.0) observed with 60% c.a. completeness.These observations provide us with the current (T<10^7 yrs) star formation properties of galaxies. The expected decrease of the star formation rate (SFR),as traced by the Halpha E.W., with decreasing clustercentric projected distance is found only when galaxies brighter than M_p=-19.5 are considered. We also include in our analysis Near Infrared data, providing us with informations on the old (T>10^9yrs) stars. Put together, the young and the old stellar indicators give the ratio of currently formed stars over the stars formed in the past, or "birthrate" parameter b. We also determine the "global gas content" combining HI with CO observations. We define the "gas deficiency" parameter as the logarithmic difference between the gas content of isolated galaxies of a given Hubble type and the measured gas content.For the isolated objects we find that b decreases with increasing NIR luminosity. The gas-deficient objects, primarily members to the Virgo cluster, have their birthrate significantly lower than the isolated objects with normal gas content and of similar NIR luminosity. This indicates that the current star formation is regulated by the gaseous content of spirals.Whatever mechanism (most plausibly ram-pressure stripping) is responsible for the pattern of gas deficiency observed in spiral galaxies members to rich clusters, it also produces the observed quenching of the current star formation.Comment: 22 pages,14 figures,3 figures available in jpeg format.To be published in A&
