Evolución de la competencia comunicativa mediante intervención pragmática en retraso del lenguaje: estudio de caso
2021
En el presente trabajo se describe la eficacia de la evaluación e intervención pragmática en un caso de retraso del lenguaje secundario a daño cerebral infantil. La intervención logopédica adoptó un marco teórico de psicolingüística cognitiva funcional y se centró en potenciar las habilidades pragmáticas comunicativas mediante la estimulación de las categorías pragmáticas interactivas en contextos conversacionales naturales. Mediante el PREP-R (Protocolo Rápido de Evaluación Pragmática Revisado) se ha hecho un seguimiento de la orientación comunicativa de los turnos, la predictibilidad, la eficacia comunicativa, la habilidad pragmática (general, específica y gramatical) y los elementos que …
Factors Behind Junk DNA in Bacteria
2012
Although bacterial genomes have been traditionally viewed as being very compact, with relatively low amounts of repetitive and non-coding DNA, this view has dramatically changed in recent years. The increase of available complete bacterial genomes has revealed that many species present abundant repetitive DNA (i.e., insertion sequences, prophages or paralogous genes) and that many of these sequences are not functional but can have evolutionary consequences as concerns the adaptation to specialized host-related ecological niches. Comparative genomics analyses with close relatives that live in non-specialized environments reveal the nature and fate of this bacterial junk DNA. In addition, the…
A Lebesgue-type decomposition for non-positive sesquilinear forms
2018
A Lebesgue-type decomposition of a (non necessarily non-negative) sesquilinear form with respect to a non-negative one is studied. This decomposition consists of a sum of three parts: two are dominated by an absolutely continuous form and a singular non-negative one, respectively, and the latter is majorized by the product of an absolutely continuous and a singular non-negative forms. The Lebesgue decomposition of a complex measure is given as application.
Spreading of Competing Information in a Network
2020
We propose a simple approach to investigate the spreading of news in a network. In more detail, we consider two different versions of a single type of information, one of which is close to the essence of the information (and we call it good news), and another of which is somehow modified from some biased agent of the system (fake news, in our language). Good and fake news move around some agents, getting the original information and returning their own version of it to other agents of the network. Our main interest is to deduce the dynamics for such spreading, and to analyze if and under which conditions good news wins against fake news. The methodology is based on the use of ladder fermion…
Resonances over a potential well in an island
2020
In this paper we study the distribution of scattering resonances for a multidimensional semi-classical Schr\"odinger operator, associated to a potential well in an island at energies close to the maximal one that limits the separation of the well and the surrounding sea.
Disputas por el poder municipal y reforzamiento regio en el realengo valenciano. De la derrota agermanada a las cortes de 1604
2021
La introducción del procedimiento electoral de insaculación en buena parte de los municipios valencianos trató de justificarse por su virtualidad para erradicar o reducir la conflictividad generada por los tradicionales mecanismos de cooptación. Las disputas, sin embargo, no desaparecieron con el nuevo sistema y tuvieron oportunidad de expresarse en distintas fases de su aplicación. A partir del análisis de una amplia casuística se trata de mostrar las modalidades que adoptó, en el plano electoral, la pugna por el poder municipal en el marco de la insaculación durante el siglo xVI, así como su incidencia en el creciente fortalecimiento de los órganos y oficiales de la administración regia, …
The members of the “Consell General” of Valencia since the death of Ferdinand the Catholic to the “Germanías” (1515-1523)
2001
En el ámbito municipal de la Valencia foral, el Consell General de la capital del Reino destacaba por su elevado número de miembros y la amplia presencia del elemento artesanal. En este trabajo, que se enmarca cronológicamente en los años previos y coetáneos al desarrollo de las Germanías, se estudian las características de los diferentes colectivos que integraban dicha asamblea, así como los procedimientos electorales, su composición personal y grado de participación en las sesiones celebradas. Entre otras valoraciones, queda de manifiesto el moderantismo que caracterizó la actitud de dicho organismo en el transcurso de la revuelta. In the municipal field of Valencia’s city at the statutor…
Depletion of coastal predatory fish sub-stocks coincided with the largest sea urchin grazing event observed in the NE Atlantic
2020
AbstractIn this contribution, we propose fishery driven predator release as the cause for the largest grazing event ever observed in the NE Atlantic. Based on the evolving appreciation of limits to population connectivity, published and previously unpublished data, we discuss whether overfishing caused a grazer bloom of the sea urchin (Strongylocentrotus droebachiensis) resulting in overgrazing of more than 2000 km2 kelp (Laminaria hyperborea) forest along Norwegian and Russian coasts during the 1970 s. We show that coastal fisheries likely depleted predatory coastal fish stocks through modernization of fishing methods and fleet. These fish were important predators on urchins and the reduct…
Invariant approximation results in cone metric spaces
2011
Some sufficient conditions for the existence of fixed point of mappings satisfying generalized weak contractive conditions is obtained. A fixed point theorem for nonexpansive mappings is also obtained. As an application, some invariant approximation results are derived in cone metric spaces.
A product space reformulation with reduced dimension for splitting algorithms
2021
AbstractIn this paper we propose a product space reformulation to transform monotone inclusions described by finitely many operators on a Hilbert space into equivalent two-operator problems. Our approach relies on Pierra’s classical reformulation with a different decomposition, which results in a reduction of the dimension of the outcoming product Hilbert space. We discuss the case of not necessarily convex feasibility and best approximation problems. By applying existing splitting methods to the proposed reformulation we obtain new parallel variants of them with a reduction in the number of variables. The convergence of the new algorithms is straightforwardly derived with no further assump…
