El Portfolio Europeo de las Lenguas (PEL): herramienta de evaluación de la composición escrita en español como lengua extranjera
2013
Introducción Esta tesis pretende dar respuesta a uno de los desafíos que enfrentan los profesores de lenguas segundas (L2): mejorar la calidad de la evaluación de la expresión escrita. Partimos de la base del Marco Común Europeo de Referencia para las Lenguas (MCER), publicado por el Consejo de Europa con la intención de orientar la enseñanza y evaluación de lenguas, y del Portfolio Europeo de las Lenguas (PEL), cuyo propósito es aplicar en el aula los principios del MCER. Nos preguntamos si el PEL, que ha sido ampliamente experimentado en Educación Primaria y Secundaria, puede ser también útil como herramienta de evaluación de la composición escrita en niveles universitarios con estudiante…
The semantics of complex demonstratives: a defense of character theories
2021
Aquesta tesi defensa una aproximació tradicional a la semàntica de demostratius complexos, ço és, expressions com "aquesta taula" o "aquell home". A la teoria clàssica, els demostratius complexos funcionen com qualsevol altre díctic: tal com ocorre amb paraules com ara "jo", "ella" o "ací", es tracta termes que depenen del context i que estan dotats d'un significat descriptiu anomenat "caràcter" que ajuda a fixar-ne referent en cada situació d’ús però que no juga cap més rol una vegada aquest individu ha estat determinat. El seu contingut o contribució proposicional és, al seu torn, un simple objecte. Aquest model dels demostratius complexos es troba justificat en la mesura que les expressi…
Pragmatično usmerjeni nauk o pravnem razlaganju
2012
Izhajajoč iz dinamičnega pristopa k razumevanju tvorbe pomena avtor v tej izvirni, za Revus napisani razpravi izgradi pragmatično usmerjeni nauk o pravnem razlaganju. Ta se odmika tako od formalističnih kot protiformalističnih pogledov, saj je v skladu z njim razlaganje hkrati »odkrivanje« nekaterih pomenskih ravni in »ustvarjanje« drugih. Pomen vsakršnih (tudi pravnih) izrazov ali stavkov je torej obravnavan kot nekaj stopnjevitega, oblikovanega na več ravneh. Obenem vključuje znotraj-jezikovno razsežnost (smisel) in razsežnost razmerja »jezik-svet« (nanosnik). Pomen nikoli ni proizveden hipoma in v celoti, ampak je oblikovan postopno, po korakih. Pri tem je za dokončno izoblikovanje pomen…
Actualisation des références nutritionnelles françaises en vitamines et minéraux
2021
En 2016, l’Anses a proposé une mise à jour des références nutritionnelles pour la population adulte (femmes de 18 à 54 ans et hommes de 18 à 64 ans) dans le cadre de l’actualisation des repères de consommation alimentaire (saisine 2012-SA-0103). Par la suite, des rapports dédiés aux repères de consommation alimentaire pour les populations spécifiques (personnes âgées, enfants, femmes enceintes et allaitantes) ont été publiés en 2019, sans toutefois quede nouvelles références nutritionnelles ne soient définies par l’agence.Par ailleurs, la mise à jour de 2016 n’a concerné que les vitamines et minéraux indispensables pour lesquelles des données de consommation étaient disponibles. De ce fait,…
Secuencias ponderadoras de identificación con como en textos literarios y periodísticos cubanos (2000-2008)
2013
La presente investigación analiza, a partir de textos cubanos actuales, un tipo de construcciones que proponemos denominar «secuencias ponderadoras de identificación con como». Se explica su funcionamiento en calidad de construcción lingüística peculiar mediante la descripción e interpretación de sus características morfosintácticas y semánticas. By examining current Cuban texts, this study analyzes a type of constructions which are proposed to be denominated 'emphatic sequences of identification with como'. It tries to explain these sequences as a peculiar linguistic construction by means of the description and interpretation of their morphosyntactic and semantic characteristics.
Effective reference and current integration for large displacement interface
2016
The most common interface formulations proposed in literature are generally based on the restrictive hypothesis of small strains and small displacements and, even though their application to geometrically nonlinear problems is of paramount interest, only few contributions are available in literature. Motivations are probably due to the difficulties encountered on such formulation, as already mentioned by several authors. A pioneering formulation is the finite displacement three-dimensional interface developed by Ortiz and Pandolfi in [1], where normal and tangential traction components are evaluated with respect to the middle surface in the current configuration, producing a non-symmetric g…
Benzen i metan jako wzorce przesunięcia chemicznego 1 H i 13 C NMR w obliczeniach teoretycznych
2020
NMR spectroscopy belongs to the most versatile techniques used in chemical laboratory for testing the presence of various compounds and elucidation of their structure. In case of more complex natural products chemical intuition and experience applied to analysis of experimental spectra is often supported by theoretical modeling of NMR spectra. However, theoretical predictions should be reliable and the errors associated with the approximations inherent to the existing methods minimized. In this respect, systematic errors, present in calculation of isotropic nuclear magnetic shieldings of the studied molecule need to be minimized. Conversion of nuclear shieldings of the studied molecule to t…
Comparative Analyses between the Zero-Inertia and Fully Dynamic Models of the Shallow Water Equations for Unsteady Overland Flow Propagation
2018
The shallow water equations are a mathematical tool widely applied for the simulation of flow routing in rivers and floodplains, as well as for flood inundation mapping. The interest of many researchers has been focused on the study of simplified forms of the original set of equations. One of the most commonly applied simplifications consists of neglecting the inertial terms. The effects of such a choice on the outputs of the simulations of flooding events are controversial and are an important topic of debate. In the present paper, two numerical models recently proposed for the solution of the complete and zero-inertia forms of the shallow water equations, are applied to several unsteady f…
Impact of the terrestrial reference frame on the determination of the celestial reference frame.
2022
Currently three up-to-date Terrestrial Reference Frames (TRF) are available, the ITRF2014 from IGN, the DTRF2014 from DGFI-TUM, and JTRF2014 from JPL. All use the identical input data of space-geodetic station positions and Earth orientation parameters, but the concept of combining these data is fundamentally different. The IGN approach is based on the combination of technique solutions, while the DGFI is combining the normal equation systems. Both yield in reference epoch coordinates and velocities for a global set of stations. JPL uses a Kalman filter approach, realizing a TRF through weekly time series of geocentric coordinates. As the determination of the CRF is not independent of the T…
Method for Reproducible Shipboard Segmented Flow Analysis Ammonium Measurement Using an In-House Reference Material for Quality Control
2021
Ammonium is a fundamental nutrient for phytoplankton growth in seawater and is a key component of the microbial loop. Ammonium measured in parallel with other nutrients is crucial in understanding the small temporal scale changes in oceanographic ecology. Despite the importance of measuring ammonium at sea, owing to its lability, there is no consensus on the best method. The lack of availability of certified reference materials for ammonium in seawater also makes it difficult to assess the accuracy and reproducibility of ammonium measurements. In this study we present a modified segmented flow analysis method using ortho-phthaldialdehyde (OPA) with fluorescence detection to measure ammonium…
