La innovación educativa en la evolución de las profesiones. El caso de las Ciencias Laborales. Reflexiones y avances
2020
Las profesiones están en continuo cambio y adaptación, y ello requiere de un permanente ajuste de las competencias que los/las profesionales precisan en cada momento. La Universidad actual debe asumir un papel activo que permita dicho ajuste. Es por tanto necesario que el estamento universitario tenga un amplio conocimiento de la realidad de la profesión, así como incorporar a sus dinámicas estas necesidades. En el presente texto proponemos una aproximación a la realidad de la profesión de Graduado Social –egresado/a actual en Ciencias Laborales -como contexto de estudio, planteando el papel que la Universidad debería asumir en la actualidad como uno de sus elementos constitutivos. La impor…
Aproximaciones al uso de los cursos en línea masivos y abiertos
2019
Desde su aparición en 2008, los cursos en línea masivos y abiertos (MOOCs, por sus siglas en inglés) han despertado interés a nivel internacional. El presente número de la revista Research in Education And Learning Innovation Archives (REALIA) se enfoca en distintas aproximaciones que se han dado al uso de este tipo de cursos. Sus temas abarcan las perspectivas de estudiantes, algunas cuestiones de diseño pedagógico y el desenvolvimiento de los participantes durante la implementación. Cada artículo incluido deja lecciones aprendidas y recomendaciones para futuros estudios. Así, este número de Research in Education And Learning Innovation Archives suma al conocimiento existente y marca la pa…
Multiplicity results for asymmetric boundary value problems with indefinite weights
2004
We prove existence and multiplicity of solutions, with prescribed nodal properties, to a boundary value problem of the formu″+f(t,u)=0,u(0)=u(T)=0. The nonlinearity is supposed to satisfy asymmetric, asymptotically linear assumptions involving indefinite weights. We first study some auxiliary half-linear, two-weighted problems for which an eigenvalue theory holds. Multiplicity is ensured by assumptions expressed in terms of weighted eigenvalues. The proof is developed in the framework of topological methods and is based on some relations between rotation numbers and weighted eigenvalues.
All-Possible-Couplings Approach to Measuring Probabilistic Context.
2013
From behavioral sciences to biology to quantum mechanics, one encounters situations where (i) a system outputs several random variables in response to several inputs, (ii) for each of these responses only some of the inputs may "directly" influence them, but (iii) other inputs provide a "context" for this response by influencing its probabilistic relations to other responses. These contextual influences are very different, say, in classical kinetic theory and in the entanglement paradigm of quantum mechanics, which are traditionally interpreted as representing different forms of physical determinism. One can mathematically construct systems with other types of contextuality, whether or not …
SNPs detection by eBWT positional clustering
2019
Sequencing technologies keep on turning cheaper and faster, thus putting a growing pressure for data structures designed to efficiently store raw data, and possibly perform analysis therein. In this view, there is a growing interest in alignment-free and reference-free variants calling methods that only make use of (suitably indexed) raw reads data. We develop the positional clustering theory that (i) describes how the extended Burrows–Wheeler Transform (eBWT) of a collection of reads tends to cluster together bases that cover the same genome position (ii) predicts the size of such clusters, and (iii) exhibits an elegant and precise LCP array based procedure to locate such clusters in the e…
Heat rectification in He II counterflow in radial geometries
2018
Abstract We consider heat rectification in radial flows of turbulent helium II, where heat flux is not described by Fourier's law, but by a more general law. This is different from previous analyses of heat rectification, based on such law. In our simplified analysis we show that the coupling between heat flux and the gradient of vortex line density plays a decisive role in such rectification. Such rectification will be low at low and high values of the heat rate, but it may exhibit a very high value at an intermediate value of the heat rate. In particular, for a given range of values for the incoming heat ow, the outgoing heat flow corresponding to the exchange of internal and external tem…

Estrategias docentes digitales: una aproximación desde la Didáctica
2019
espanolLa sociedad actual, caracterizada por el impacto de la tecnologia en los diferentes ambitos de la vida cotidiana, construye nuevas formas de hacer, de vivir, de ser, de interactuar, de conocer y de aprender. En este contexto, la escuela no queda al margen de este proceso de cambio e innovacion y se requiere de la puesta en practica de estrategias didacticas digitales para atender a las caracteristicas y demandas del alumnado que escolariza. Sobre ello y, a partir de los resumenes de los articulos que componen el monografico, se realiza un analisis de contenido que ha permitido identificar las palabras de uso frecuente en el ambito analizado, empleando la herramienta Atlas.ti.8 para l…
On the limit velocity and buckling phenomena of axially moving orthotropic membranes and plates
2011
In this paper, we consider the static stability problems of axially moving orthotropic membranes and plates. The study is motivated by paper production processes, as paper has a fiber structure which can be described as orthotropic on the macroscopic level. The moving web is modeled as an axially moving orthotropic plate. The original dynamic plate problem is reduced to a two-dimensional spectral problem for static stability analysis, and solved using analytical techniques. As a result, the minimal eigenvalue and the corresponding buckling mode are found. It is observed that the buckling mode has a shape localized in the regions close to the free boundaries. The localization effect is demon…
Complex dynamics, hidden attractors and continuous approximation of a fractional-order hyperchaotic PWC system
2018
In this paper, a continuous approximation to studying a class of PWC systems of fractionalorder is presented. Some known results of set-valued analysis and differential inclusions are utilized. The example of a hyperchaotic PWC system of fractional order is analyzed. It is found that without equilibria, the system has hidden attractors.
