Perseo en el romancero clásico: las Rosas de romances de Juan de Timoneda

El presente trabajo se plantea como un análisis de tres poemas sobre el mito de Perseo recogidos en las Rosas de Romances del valenciano Juan de Timoneda (1573). Creemos que se trata de los primeros textos de la Literatura Española que abordan este mito, anteriores en quince años al romance sobre Perseo y Andrómeda de Juan de la Cueva (1588). Nuestro estudio muestra la dependencia de los romances de Timoneda respecto a la traducción de las Metamorfosis de Ovidio llevada a cabo por Jorge de Bustamante en la primera mitad de esa misma centuria, y a su vez un afán de suprimir algunos episodios claves de la fábula para constituir un todo más cercano al mundo caballeresco.

La Dánae burlesca de Pedro Silvestre: edición anotada

Ofrecemos en el presente trabajo la edición de un poema basado en el mito de Dánae que fue compuesto en el siglo xviii por un autor que firmaba bajo el seudónimo de Pedro Silvestre. El mayor interés de esta composición radica en el hecho de ser una de las escasas muestras que encontramos en la literatura española de una fábula burlesca que desarrolla este mito clásico. Nuestro trabajo ofrece la transcripción modernizada -basada en el único manuscrito existente- de este texto hasta ahora inédito, además de una breve introducción y diversas notas lingüísticas y aclaratorias. Palabras clave: mitología, Dánae y Perseo, fábula burlesca, manuscrito, Pedro Silvestre

Perseo en la Comedia tardobarroca: Ignacio Ferrera y Pasqual

Resumen: Entre los géneros que recrearon el mito de Perseo en la literatura española sobresale la comedia barroca. Lope y Calderón compusieron dos conocidas obras sobre este asunto mitológico, que llegaría a su máxima expresión dramática con el auto sacramental Perseo y Andrómeda del propio Calderón. Sin embargo, ya casi mediado el siglo xviii, es decir, en el tardobarroco, encontramos una curiosa obra debida a un cierto Ignacio Ferrera y Pasqual, que constituye una de las versiones más sui generis de la historia de Perseo. Presentamos en este artículo un análisis de esta sorprendente pieza. Palabras clave: Perseo; literatura española; comedia; barroco tardío; Ignacio Ferrera y Pasqual

Qubit authentication

Secure communication requires message authentication. In this paper we address the problem of how to authenticate quantum information sent through a quantum channel between two communicating parties with the minimum amount of resources. Specifically, our objective is to determine whether one elementary quantum message (a qubit) can be authenticated with a key of minimum length. We show that, unlike the case of classical-message quantum authentication, this is not possible.Comment: LaTeX, 8 page

Educational trends in special education in Spain : the case of the deaf

Following a brief account of Education and Special Education in Spain, I will start the paper by pointing out the different views of understanding deafness, both in hearing and deaf people. I shall then focus on the Spanish situation regarding the education models for the deaf, drawing a distinction between models regarding language (oralism vs. bilingualism) and models regarding education (special education vs. inclusive education), The paper will end with a vision of the education for the deaf paying special attention to the fact that school teachers and administrators have a very early and intense role in the lives of deaf children. It will point out that early intervention is a desirable goal, but carries some dangers regarding deaf children's social and emotional development.peer-reviewe

Probabilistic Bounds on the Length of a Longest Edge in Delaunay Graphs of Random Points in d-Dimensions

Motivated by low energy consumption in geographic routing in wireless networks, there has been recent interest in determining bounds on the length of edges in the Delaunay graph of randomly distributed points. Asymptotic results are known for random networks in planar domains. In this paper, we obtain upper and lower bounds that hold with parametric probability in any dimension, for points distributed uniformly at random in domains with and without boundary. The results obtained are asymptotically tight for all relevant values of such probability and constant number of dimensions, and show that the overhead produced by boundary nodes in the plane holds also for higher dimensions. To our knowledge, this is the first comprehensive study on the lengths of long edges in Delaunay graphsComment: 10 pages. 2 figures.

L'influence de la stratégie internationale des multinationales sur leurs programmes de mobilité internationale

Notre étude s’intéresse à la façon dont les entreprises multinationales utilisent et gèrent la mobilité internationale de leurs employés. Plus précisément, nous cherchions à déterminer l’importance que les entreprises multinationales accordent à leur stratégie internationale au moment de décider de la façon d’utiliser l’expatriation et de la gérer au moyen des programmes de mobilité internationale. Bien que l’objet principal de notre recherche soit d’observer l’influence de la stratégie internationale sur ces programmes, nous avons cherché également à identifier d’autres caractéristiques de chaque entreprise et de son environnement susceptibles de les influencer. Cette démarche nous a permis de déterminer si les entreprises multinationales qui adoptent des programmes de mobilité internationale similaires partagent une même orientation stratégique au niveau international ou plutôt d’autres caractéristiques. Notre étude, effectuée auprès de professionnels de la GRH responsables de la gestion de la mobilité internationale, visait, dans un premier temps, à identifier le type de stratégie internationale privilégiée par les entreprises, ainsi que l’approche de la gestion internationale des ressources humaines qu’elles favorisent. Dans un deuxième temps, nous avons cherché à identifier le type de programme de mobilité internationale en place dans chaque entreprise à partir de l’analyse de leurs composantes (politiques et pratiques RH). Nous avons tiré deux conclusions principales de notre étude. Premièrement, la mobilité internationale, plus particulièrement l’expatriation, constitue toujours un important outil d’expansion et de survie des entreprises multinationales. Deuxièmement, les entreprises multinationales l’utilisent différemment en fonction de leurs objectifs stratégiques et la gèrent de façon très pragmatique, en tenant compte d’une panoplie de facteurs tels le nombre d’expatriés, la culture managériale de l’entreprise, les caractéristiques de leur secteur d’activité, leur expérience et les difficultés rencontrées en cours de route.Our study looks at how multinational corporations use and manage the international mobility of their employees. More specifically, we sought to determine to which extent multinationals consider their international management strategy in deciding how to use the expatriation managed through international mobility programs. Although the main purpose of our research is to observe the influence of the international management strategy on these programs, we also sought to identify other characteristics of each firm and its environment that may influence them. Our study, conducted among HR professionals responsible for management of international mobility, intended, in a first step, to identify the type of international management strategy favored by firms and the approach to international management of human resources they lead to. In a second step, we sought to identify the type of international mobility program in place in each firm from the analysis of their components (HR policies and practices). We drew two main conclusions of our study. First, international mobility, especially expatriation, is still an important tool for growth and survival of multinational corporations. Second, multinational corporations use expatriation differently depending on their strategic objectives and manage it very pragmatically, taking into account a variety of factors including the number of expatriates, the managerial culture of the company, the characteristics of their industry, their experience and difficulties encountered during the journey

Teaching based on the case method of building collective protection

One of the fundamental aspects in the adaptation of the teaching to the European higher education is changing based models of teacher education to models based on student learning. In this work we present an educational experience developed with the teaching method based on the case method, with a clearly multidisciplinary. The experience has been developed in the teaching of analysis and verification of safety rails. This is a multidisciplinary field that presents great difficulties during their teaching. The use of the case method has given good results in the competences achieved by student
