A study of (im)politeness on the Facebook pages of the main Spanish political parties: the gender variable and face acts
2019
Este estudio pretende conocer qué sexo tiene mayor participación en las páginas de Facebook de los 5 principales partidos políticos españoles: Partido Socialista Obrero Español (PSOE), Partido Popular (PP), Ciudadanos, Unidos Podemos y Vox y si el comportamiento en función del sexo difiere en torno a los actos de refuerzo de la imagen (FFA - face flattering acts) y a los actos de ataque a la imagen (FTA - face threatening acts). Para ello, se ha elaborado un análisis métrico de la campaña electoral de las elecciones generales del año 2019 y se ha recogido un corpus de 2500 comentarios durante el último día, el 26 de abril.
Motivations, engagement and adoption of e-WOM in restaurants.
2022
Resumen El objetivo del presente trabajo fue estudiar el efecto que tienen las motivaciones para consultar y escribir e-WOM sobre el compromiso con el e-WOM y la influencia de dicho compromiso en la adopción del e-WOM consultado. Para analizar estas relaciones, se realizó una investigación empírica aplicada en el contexto de los restaurantes. El ámbito geográfico fue Ecuador, con una muestra de 461 consumidores. Se utilizó un modelo de ecuaciones estructurales y se validó la cadena de relaciones. Los resultados confirmaron las relaciones entre estas variables; además, se presentaron implicaciones académicas interesantes para profundizar en el estudio sobre el compromiso con el e-WOM, así co…
The Importance of Empowerment in Entrepreneurship
2017
Empowerment comes at a time when global competition and change require people to take initiative and be innovative. Based on the active, persistent, and change-oriented behaviors associated with psychological empowerment, the chapter states that empowerment can contribute to entrepreneurship. The dimensions of empowerment that suggest a theoretical and empirical link with entrepreneurial behavior are discussed. Several propositions regarding the interplay between empowerment and entrepreneurship are formulated. The chapter describes paths to promote empowerment and entrepreneurship in applied context and suggests future directions to advance research on empowerment in the field of entrepren…
Common fixed points of g-quasicontractions and related mappings in 0-complete partial metric spaces
2012
Abstract Common fixed point results are obtained in 0-complete partial metric spaces under various contractive conditions, including g-quasicontractions and mappings with a contractive iterate. In this way, several results obtained recently are generalized. Examples are provided when these results can be applied and neither corresponding metric results nor the results with the standard completeness assumption of the underlying partial metric space can.

Derivation of a Homogenized Two-Temperature Model from the Heat Equation
2014
This work studies the heat equation in a two-phase material with spherical inclusions. Under some appropriate scaling on the size, volume fraction and heat capacity of the inclusions, we derive a coupled system of partial differential equations governing the evolution of the temperature of each phase at a macroscopic level of description. The coupling terms describing the exchange of heat between the phases are obtained by using homogenization techniques originating from [D. Cioranescu, F. Murat: Coll\`ege de France Seminar vol. 2.

Extensions and corona decompositions of low-dimensional intrinsic Lipschitz graphs in Heisenberg groups
2020
This note concerns low-dimensional intrinsic Lipschitz graphs, in the sense of Franchi, Serapioni, and Serra Cassano, in the Heisenberg group $\mathbb{H}^n$, $n\in \mathbb{N}$. For $1\leq k\leq n$, we show that every intrinsic $L$-Lipschitz graph over a subset of a $k$-dimensional horizontal subgroup $\mathbb{V}$ of $\mathbb{H}^n$ can be extended to an intrinsic $L'$-Lipschitz graph over the entire subgroup $\mathbb{V}$, where $L'$ depends only on $L$, $k$, and $n$. We further prove that $1$-dimensional intrinsic $1$-Lipschitz graphs in $\mathbb{H}^n$, $n\in \mathbb{N}$, admit corona decompositions by intrinsic Lipschitz graphs with smaller Lipschitz constants. This complements results that…
Инфинитезимальная проблема центра на нулевых циклах и гипотеза композиции
2021
Изучается аналог классической инфинитезимальной проблемы центра на плоскости для нулевых циклов. Для этого случая определяется функция смещения и доказывается, что она тождественно равна нулю тогда и только тогда, когда деформация имеет композиционный фактор. Иными словами, гипотеза композиции верна в этом случае, в отличие от тангенциальной проблемы центра для нулевых циклов. Приводятся примеры применения результатов.

A Model for High-Cycle Fatigue in Polycrystals
2018
A grain-scale formulation for high-cycle fatigue inter-granular degradation in polycrystalline aggregates is presented. The aggregate is represented through Voronoi tessellations and the mechanics of individual bulk grains is modelled using a boundary integral formulation. The inter-granular interfaces degrade under the action of cyclic tractions and they are represented using cohesive laws embodying a local irreversible damage parameter that evolves according to high-cycle continuum damage laws. The consistence between cyclic and static damage, which plays an important role in the redistribution of inter-granular tractions upon cyclic degradation, is assessed at each fatigue solution jump,…
Hybrid Equilibrium Finite Element Formulation for Cohesive Crack Propagation
2019
Equilibrium elements have been developed in hybrid formulation with independent equilibrated stress fields on each element. Traction equilibrium condition, at sides between adjacent elements and at sides of free boundary, is enforced by use of independent displacement laws at each side, assumed as Lagrangian parameters. The displacement degrees of freedom belongs to the element side, where an extrinsic interface can be embedded. The embedded interface is defined by the same stress fields of the hybrid equilibrium element and it does not require any additional degrees of freedom. The extrinsic interface is developed in the consistent thermodynamic framework of damage mechanics with internal …
