The effect of language use on the financial performance of microfinance banks: Evidence from cross-border activities in 74 countries
2019
Abstract This multi-year study examines the relationship between financial performance and language use, observing 405 partnerships between microfinance banks and their international financial partners in 74 countries. Drawing on language research in international business, we find that microfinance banks based in English-speaking, French-speaking, and Spanish-speaking countries have higher performance. Furthermore, the linguistic distance between the home country of a microfinance bank and the home country of its international partner(s) is negatively related to its financial performance. Our large-scale study confirms the effect of language use on organization-level financial performance …
An overdetermined problem for the anisotropic capacity
2015
We consider an overdetermined problem for the Finsler Laplacian in the exterior of a convex domain in \({\mathbb {R}}^{N}\), establishing a symmetry result for the anisotropic capacitary potential. Our result extends the one of Reichel (Arch Ration Mech Anal 137(4):381–394, 1997), where the usual Newtonian capacity is considered, giving rise to an overdetermined problem for the standard Laplace equation. Here, we replace the usual Euclidean norm of the gradient with an arbitrary norm H. The resulting symmetry of the solution is that of the so-called Wulff shape (a ball in the dual norm \(H_0\)).
Concienciación juvenil frente al COVID-19 en España y Latinoamérica: análisis de spots en YouTube
2021
Introducción. Las consecuencias socio-sanitarias y económicas del COVID-19 llevó a los países a adoptar estrategias comunicativas de carácter preventivo, que difundieron en medios sociales para amplificar su difusión. Esta investigación analiza spots del contexto español y latinoamericano (N=100) orientados a concienciar a los jóvenes frente al COVID-19 publicados durante el periodo de 1 septiembre 2020 a 10 enero 2021 y accesibles en YouTube. Metodología. La metodología es mixta: cualitativa, se analizan variables comunicativas, técnico-narrativas y afectivo-emocionales; y cuantitativa, con análisis descriptivo de los datos y posterior análisis de varianza para identificar las diferencias …
Distance education and learning processes. A survey at University of Catania during the COVID-19 pandemic.
2021
The emergency situation caused by the COVID-19 pandemic required all Italian universities to implement alternative teaching strategies to traditional face-to-face lessons. At the University of Catania, this situation prompted the start of distance learning paths in a synchronous mode at the very beginning of the emergency. At the same time, the lecturers were encouraged to video-record the lessons in order to make them available to students also in asynchronous mode. On the basis of this emergency situation, an investigation was immediately launched to identify the consequences of the new teaching methods on student learning processes; the research began in the first phase of the lockdown i…
Fixed point theorems in generalized partially orderedG-metric spaces
2010
In this paper, we consider the concept of a $\Omega$-distance on a complete partially ordered G-metric space and prove some fixed point theorems.
The audio describer as a cultural mediator
2017
AbstractAudio Description (AD) is a modality of audiovisual translation that consists of making cultural products accessible to people who are blind or partially-sighted. Our study focuses on the contrastive analysis of the AD of four films in English and Spanish, our objective being to determine how the same visual cultural reference is described in two languages and for two target cultures. Using a descriptive methodology, we categorise and analyse cultural references followingDíaz Cintas and Remael’s (2007)classification and determine the translation strategies used. Our research shows that the decisions that the describer makes are conditioned by the distance, not only geographical but …
De la distance – Prendre en compte des publics lointains et décentrer la réflexion méthodologique : sociodidactique ou sémiodidactique ?
2013
International audience; Après avoir défini la distance en particulier dans les systèmes d’enseignement/apprentissage, on s’attache dans cet article à mettre en évidence les besoins des étudiants (mondiaux, désormais) apprenant à distance et les modes possibles d’analyse puis de prise en compte de ces besoins par les enseignants chargés d’enseignement à distance, et d’encadrement de recherche. Dans un second temps, est posée la question plus théorique de savoir comment approcher la variété des publics, leurs besoins en termes d’enseignement et apprentissage et leurs caractéristiques : une sociodidactique, dans la droite ligne de la sociolinguistique ? ou plutôt, une sémiodidactique qui se fo…
Classification trees for preference data: a distance-based approach
2014
In the framework of preference rankings, when the interest lies in explaining which predictors and which interactions among predictors are able to explain the observed preference structures, the possibility to derive consensus measures using a classi cation tree represents a novelty and an important tool given its easy interpretability. In this work we propose the use of a multivariate decision tree where a weighted Kemeny distance is used both to evaluate the distances between rankings and to de ne an impurity measure to be used in the recursive partitioning. The proposed approach allows also to weight di erently high distances in rankings in the top and in the bottom alternatives.
Empirical measures and Vlasov hierarchies
2013
The present note reviews some aspects of the mean field limit for Vlasov type equations with Lipschitz continuous interaction kernel. We discuss in particular the connection between the approach involving the N-particle empirical measure and the formulation based on the BBGKY hierarchy. This leads to a more direct proof of the quantitative estimates on the propagation of chaos obtained on a more general class of interacting systems in [S.Mischler, C. Mouhot, B. Wennberg, arXiv:1101.4727]. Our main result is a stability estimate on the BBGKY hierarchy uniform in the number of particles, which implies a stability estimate in the sense of the Monge-Kantorovich distance with exponent 1 on the i…
Estimating the gravity equation with the actual number of exporting firms
2013
Para estimar correctamente el efecto de los costes de comerciar sobre las exportaciones de las empresas, la ecuación de gravedad debe controlar por el número de empresas que opera en el mercado internacional. Debido a la ausencia de datos, estudios anteriores han controlado esta variable mediante técnicas econométricas que también pueden generar estimaciones sesgadas. Para superar estos problemas este trabajo estima una ecuación de gravedad utilizando una nueva base de datos de la OCDE y EUROSTAT , que incluye el número de empresas exportadoras en cada relación bilateral. Nuestros resultados muestran que no controlar el margen extensivo genera sesgos muy importantes en la estimación de los …
