The role of news values in the discur-sive construction of the Brexit refer-endum in the UK press
2022
El objetivo principal de este estudio es explorar el discurso periodístico de la campaña del referéndum del Brexit en Reino Unido desde la perspectiva de los estudios del discurso asistidos por corpus (CADS). En concreto, se analiza cómo se construyeron discursivamente diferentes temas y debates relacionados con el Brexit en la cobertura de la prensa británica de calidad durante la campaña del referéndum. Asimismo, se investigan las diferencias ideológicas en la construcción discursiva de dicha cobertura según las afiliaciones políticas (izquierda-derecha) y las posturas ideológicas hacia el Brexit (Bandos de Salida-Permanencia). Para ello, se recopiló un corpus de cuatro diarios británicos…
Generalized Browder’s Theorem and SVEP
2007
A bounded operator \(T \in L(X), X\) a Banach space, is said to verify generalized Browder’s theorem if the set of all spectral points that do not belong to the B-Weyl’s spectrum coincides with the set of all poles of the resolvent of T, while T is said to verify generalized Weyl’s theorem if the set of all spectral points that do not belong to the B-Weyl spectrum coincides with the set of all isolated points of the spectrum which are eigenvalues. In this article we characterize the bounded linear operators T satisfying generalized Browder’s theorem, or generalized Weyl’s theorem, by means of localized SVEP, as well as by means of the quasi-nilpotent part H0(λI − T) as λ belongs to certain …
A bounded version of bosonic creation and annihilation operators and their related quasi-coherent states
2007
Coherent states are usually defined as eigenstates of an unbounded operator, the so-called annihilation operator. We propose here possible constructions of {\em quasi-coherent states}, which turn out to be {\em quasi} eigenstate of a \underline{bounded} operator related to an annihilation-like operator. We use this bounded operator to construct a sort of modified harmonic oscillator and we analyze the dynamics of this oscillator from an algebraic point of view.
Culture and current account balances
2014
This article contributes to the literature of current account balances by introducing cultural variables that until now have been omitted. The World Values Survey indicates that the Roman Catholics do not consider thrift as important as others. We propose that Catholic countries tend to run current account deficits. This result remains robust even if we control for close to all of the determinants that have been included in previous studies. We find evidence that the inclination of Catholic countries to have high levels of uncertainty avoidance goes to a great length in explaining the result. peerReviewed
Decay estimates in the supremum norm for the solutions to a nonlinear evolution equation
2014
We study the asymptotic behaviour, as t → ∞, of the solutions to the nonlinear evolution equationwhere ΔpNu = Δu + (p−2) (D2u(Du/∣Du∣)) · (Du/∣Du∣) is the normalized p-Laplace equation and p ≥ 2. We show that if u(x,t) is a viscosity solution to the above equation in a cylinder Ω × (0, ∞) with time-independent lateral boundary values, then it converges to the unique stationary solution h as t → ∞. Moreover, we provide an estimate for the decay rate of maxx∈Ω∣u(x,t) − h(x)∣.
Ultrarelativistic bound states in the spherical well
2016
We address an eigenvalue problem for the ultrarelativistic (Cauchy) operator $(-\Delta )^{1/2}$, whose action is restricted to functions that vanish beyond the interior of a unit sphere in three spatial dimensions. We provide high accuracy spectral datafor lowest eigenvalues and eigenfunctions of this infinite spherical well problem. Our focus is on radial and orbital shapes of eigenfunctions. The spectrum consists of an ordered set of strictly positive eigenvalues which naturally splits into non-overlapping, orbitally labelled $E_{(k,l)}$ series. For each orbital label $l=0,1,2,...$ the label $k =1,2,...$ enumerates consecutive $l$-th series eigenvalues. Each of them is $2l+1$-degenerate. …
An extension of Guo's theorem via k--contractive retractions
2006
Abstract Let X be a infinite-dimensional Banach space. We generalize Guo's Theorem [D.J. Guo, Eigenvalues and eigenvectors of nonlinear operators, Chinese Ann. Math. 2 (1981) 65–80 [English]] to k- ψ -contractions and condensing mappings, under a condition which depends on the infimum k ψ of all k ⩾ 1 for which there exists a k- ψ -contractive retraction of the closed unit ball of the space X onto its boundary.
Revista electrónica interuniversitaria de formación del profesorado
2016
Este estudio forma parte de una investigación cuyo propósito es aportar evidencias acerca de las percepciones del estudiantado de la Universidad de Valencia respecto a la igualdad y la violencia de género. Se trata de un trabajo puli-meotodológico, que integra un enfoque cualitativo y cuantitativo, a través del uso de un cuestionario escala y grupos de discusión. El fin es valorar la situación actual de estas dimensiones, estableciendo diferencias y semejanzas en función del sexo y el ámbito de conocimiento para comprender en profundidad el fenómeno. En este artículo se ha abordado un factor concreto: la figura del profesorado universitario, clave para lograr una iguadlad efecitva entre muj…
The The Land Cadastre in Italy and some fiscal implications: a case study
2023
The Land Cadastre, as an inventory of all relevant real estate in a territory, and most importantly, as a national tax system is, or at least should be, the protago-nist of fiscal, social and civil implications affecting the Italian context. According to unitary farmland incomes, the last revision dates back to 1978-1979, a period that no longer reflects the country’s current socioeconomic situation and does not consider the changes the land market has undergone over the years. Through the analysis of 183 purchases and sales of agricultural land in two districts in western Sicily, this research aims at verifying the adequacy or inadequacy of the current cadastral tariffs. Based on the price…
La vacuna del Virus del Papiloma Humano en los titulares de prensa
1970
Los periódicos ponen textos a disposición del público mediante procesos y prácticas entre los que se sitúan los valores noticiosos, definidos como criterios en las rutinas periodísticas que habilitan a los editores a decidir que historias se publican y cuáles no. Por tanto, intentaremos identificar desde un punto de vista cualitativo, los valores noticiosos en los titulares de las noticias, de diferentes periódicos, publicadas entre enero de 2006, año en que fue aprobada la vacuna por la autoridades de la administración americana (FDA) y mayo de 2009, mes posterior al episodio en que dos adolescentes valencianas experimentaron crisis convulsivas tras ser inmunizadas. Tratando de identificar…
