The article analyzes the legal regime of Euskara in the education system of the Autonomous Community of the Basque Country (capv). In the capv, the legislation recognizes the right to choose the language of study during the educational cycle. The students are separated into different classrooms based on their language preference. This system of separation (of language models) has made it possible to make great strides, although its implementation also suggests aspects which, from the perspective of a pluralistic Basque society on its way towards greater social, political and language integration, call for further reflection The general model for language planning in the capv was fashioned in the eighties as a model characterized by the guarantee of spaces of language freedom, and the educational system was charged with making the learning of the region’s autochthonous language more widespread. At this point, we already have a fair degree of evidence on which to base an analysis of the system of language models and we are in a position to conclude that perhaps the educational system was given too heavy a burden. Official studies on language performance of Basque schoolchildren show (in a way that is now fully verified) that not all the students who finish their mandatory period of schooling achieve the level of knowledge of Euskara required by the regulations. When faced with this reality, it becomes necessary for us to articulate some alternative to the current configuration of the system of language models, one that will make it possible in the future to have a Basque society that is linguistically more integrated, thereby avoiding having the knowledge or lack of knowledge of one of the official languages become a language barrier between two communities. Many sides have urged a reconsideration of the system of language models. The Basque Parliament itself has requested the Department of Education to design a new system. This article analyzes the legal foundations on which the current system is built and explores the potential avenues for legal cooperation that would make it possible to move towards a new system aimed at guaranteeing higher rates of bilingualism. The system would be sufficiently flexible so as to be able to respond to and accommodate the different sociolinguistic realities of the region.

[ES]Los cateterismos venosos periféricos son los dispositivos que con mayor frecuencia se emplean en el acceso vascular para pacientes que se encuentran ingresados en unidades hospitalarias. Estos catéteres son reemplazados sistemáticamente cada tres o cuatro días para tratar de prevenir la flebitis como refleja la guía de Center for Disease control and prevention (CDC) y por extensión, nuestro sistema de salud de Osakidetza. Sin embargo, la evidencia que apoya esta práctica no está del todo cimentada.El objetivo de esta revisión bibliográfica es evaluar la efectividad de esta práctica clínica tan integrada en la vida diaria de los profesionales de enfermería mediante la evaluación de la evidencia científica existente hasta el momento.Se realizo una búsqueda exhaustiva en diferentes bases de datos electrónicas desde Octubre de 2012 hasta Abril del año 2013. Se descargaron los textos completos de aquellos artículos que pudiesen ser potencialmente útiles en el estudio y se analizaron bajo los criterios de inclusión y selección. Los siete artículos seleccionados como válidos no demuestran que sea necesario sustituir de forma sistemática el catéter venoso periférico así como lo defiende la CDC. Debido a ello, se podría abolir esta práctica clínica que reduciría significativamente el dolor y las molestias que sufren los pacientes día a día, el tiempo que el personal de enfermería dedica en este tipo de prácticas, además de todo el coste sanitario que ello con lleva.

The aim of the present study is to analyse the influence of different large-sided games (LSGs) on the physical and physiological variables in under-12s (U12) and -13s (U13) soccer players. The effects of the combination of different number of players per team, 7, 9, and 11 (P7, P9, and P11, respectively) with three relative pitch areas, 100, 200, and 300 m(2) (A100, A200, and A300, respectively), were analysed in this study. The variables analysed were: 1) global indicator such as total distance (TD); work:rest ratio (W:R); player-load (PL) and maximal speed (V-max); 2) heart rate (HR) mean and time spent in different intensity zones of HR (<75%, 75-84%, 84-90% and >90%), and; 3) five absolute (<8, 8-13, 13-16 and >16 Km h(-1)) and three relative speed categories (<40%, 40-60% and >60% V-max). The results support the theory that a change in format (player number and pitch dimensions) affects no similarly in the two players categories. Although it can seem that U13 players are more demanded in this kind of LSG, when the work load is assessed from a relative point of view, great pitch dimensions and/or high number of player per team are involved in the training task to the U12 players. The results of this study could alert to the coaches to avoid some types of LSGs for the U12 players such as:P11 played in A100, A200 or A300, P9 played in A200 or A300 and P7 played in A300 due to that U13>U12 in several physical and physiological variables (W:R, time spent in 84-90% HRmax, distance in 8-13 and 13-16 Km h(-1) and time spent in 40-60% V-max). These results may help youth soccer coaches to plan the progressive introduction of LSGs so that task demands are adapted to the physiological and physical development of participants.
