An austerity-driven energy reform

In July 2013, the government approved a major overhaul of the Spanish electricity sector to correct existing imbalances that have led to an exponential increase of regulated electricity costs and a huge tariff deficit. The reform addresses the problem of financial sustainability of the sector, severely affected by weak demand and overcapacity. Previous regulation introduced in 2012 and early 2013, also aimed at restoring financial stability of the sector, failed to correct the tariff shortfall and new regulatory measures were needed to reduce the 4.5 billion euros forecasted deficit for 2013. The frequent change of the rules of the game in the sector has created regulatory uncertainty, more so as it is not clear that the present reform will be sufficient to eliminate the deficit. Moreover, the government has left the door open to new regulation that would deal with the price formation system. In general, short run financial criteria have prevailed, while efficiency principles and a long run perspective have little weight in the reform.

Streamflow response of a small forested catchment on different timescales

The hydrological response of a catchment to rainfall on different timescales is result of a complex system involving a range of physical processes which may operate simultaneously and have different spatial and temporal influences. This paper presents the analysis of streamflow response of a small humid-temperate catchment (Aixola, 4.8 km(2)) in the Basque Country on different timescales and discusses the role of the controlling factors. Firstly, daily time series analysis was used to establish a hypothesis on the general functioning of the catchment through the relationship between precipitation and discharge on an annual and multiannual scale (2003-2008). Second, rainfall-runoff relationships and relationships among several hydrological variables, including catchment antecedent conditions, were explored at the event scale (222 events) to check and improve the hypothesis. Finally, the evolution of electrical conductivity (EC) during some of the monitored storm events (28 events) was examined to identify the time origin of waters. Quick response of the catchment to almost all the rainfall events as well as a considerable regulation capacity was deduced from the correlation and spectral analyses. These results agree with runoff event scale data analysis; however, the event analysis revealed the non-linearity of the system, as antecedent conditions play a significant role in this catchment. Further, analysis at the event scale made possible to clarify factors controlling (precipitation, precipitation intensity and initial discharge) the different aspects of the runoff response (runoff coefficient and discharge increase) for this catchment. Finally, the evolution of EC of the waters enabled the time origin (event or pre-event waters) of the quickflow to be established; specifically, the conductivity showed that pre-event waters usually represent a high percentage of the total discharge during runoff peaks. The importance of soil waters in the catchment is being studied more deeply.

Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens

This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme temperature and relative humidity conditions making comparative tests of stress before and after aging using different adhesives. Moreover, a comparison has been made with IT tecniques and conventional methods for calculating stresses in F114 steel. Implementation of Structural Health Monitoring techniques on real aircraft during their life cycle requires a study of the behaviour of FBG sensors and their wiring under real conditions, before using them for a long time. To simulate aging, specimens were stored in a climate chamber at 70 degrees C and 90% RH for 60 days. This study is framed within the Structural Health Monitoring (SHM) and Non Destructuve Evaluation (NDE) research lines, integrated into the avionics area maintained by the Aeronautical Technologies Centre (CTA) and the University of the Basque Country (UPV/EHU).

The Economics of "Why is it so hard to save a threatened Language?"

We study the language choice behavior of bilingual speakers in modern societies, such as the Basque Country, Ireland andWales. These countries have two o cial languages:A, spoken by all, and B, spoken by a minority. We think of the bilinguals in those societies as a population playing repeatedly a Bayesian game in which, they must choose strategically the language, A or B, that might be used in the interaction. The choice has to be made under imperfect information about the linguistic type of the interlocutors. We take the Nash equilibrium of the language use game as a model for real life language choice behavior. It is shown that the predictions made with this model t very well the data about the actual use, contained in the censuses, of Basque, Irish and Welsh languages. Then the question posed by Fishman (2001),which appears in the title, is answered as follows: it is hard, mainly, because bilingual speakers have reached an equilibrium which is evolutionary stable. This means that to solve fast and in a re ex manner their frequent language coordination problem, bilinguals have developed linguistic conventions based chie y on the strategy 'Use the same language as your interlocutor', which weakens the actual use of B.1

Image-based delineation and classification of built heritage masonry

[EN]Fundación Zain is developing new built heritage assessment protocols. The goal is to objectivize and standardize the analysis and decision process that leads to determining the degree of protection of built heritage in the Basque Country. The ultimate step in this objectivization and standardization effort will be the development of an information and communication technology (ICT) tool for the assessment of built heritage. This paper presents the ground work carried out to make this tool possible: the automatic, image-based delineation of stone masonry. This is a necessary first step in the development of the tool, as the built heritage that will be assessed consists of stone masonry construction, and many of the features analyzed can be characterized according to the geometry and arrangement of the stones. Much of the assessment is carried out through visual inspection. Thus, this process will be automated by applying image processing on digital images of the elements under inspection. The principal contribution of this paper is the automatic delineation the framework proposed. The other contribution is the performance evaluation of this delineation as the input to a classifier for a geometrically characterized feature of a built heritage object. The element chosen to perform this evaluation is the stone arrangement of masonry walls. The validity of the proposed framework is assessed on real images of masonry walls.

Intermediate Macroeconomics : Self-evaluation exercises

This resource can be particularly helpful to students taking the Intermediate Macroeconomics course, which corresponds to the second year of the current Degree in Economics at the University of the Basque Country UPV/ EHU. The precise content of this resource is a collection of eight chapters of multiple-choice questions. For each question the user is asked to guess which the correct answer is. Finally, the tool will return all the correct answers for the whole test, thereby allowing the user to check the validity of his/her answers. A remarkable feature of the tool is that it has been edited in three versions, for the three languages (Spanish, Basque and English) in which the subject is taught at the UPV/EHU.

Gobernanza, procesos participativos y conflictos en los Espacios Naturales Protegidos de la Comunidad Autónoma del País Vasco

[ES] El objetivo del artículo es explorar la potencialidad de la Evaluación Multi-criterio Social como enfoque metodológico para evaluar Espacios Naturales Protegidos (ENP) e iniciar un proceso de discusión sobre la conveniencia de incorporar esta metodología para la gobernanza de la Red Natura 2000 de la Comunidad Autónoma de Euskadi. Del caso de estudio analizado se desprende que la inclusión de la población local en un proceso participativo dirigido a la planificación y manejo de los ENP contribuiría a reducir el número y calado de conflictos potenciales. Asimismo, facilitaría la gobernanza efectiva de los ENP, lo que parece un reto ineludible para que las áreas protegidas logren sus objetivos y funciones.

Towards a participatory integrated assessment approach for planning and managing Natura 2000 network sites

Managing protected areas implies dealing with complex social-ecological systems where multiple dimensions (social, institutional, economic and ecological) interact over time for the delivery of ecosystem services. Uni-dimensional and top-down management approaches have been unable to capture this complexity. Instead, new integrated approaches that acknowledge the diversity of social actors in the decision making process are required. In this paper we put forward a novel participatory assessment approach which integrates multiple methodologies to reflect different value articulating institutions in the case of a Natura 2000 network site in the Basque Country. It integrates within a social multi-criteria evaluation framework, both the economic values of ecosystem services through a choice experiment model and ecological values by means of a spatial bio-geographic assessment. By capturing confronting social and institutional conflicts in protected areas the participatory integrated assessment approach presented here can help decision makers for better planning and managing Natura 2000 sites.

Actividad agraria y urbanización: Desarrollo de un protocolo de valoración

[ES] Con demasiada frecuencia, especialmente en los espacios periurbanos, el suelo agrario es ocupado por actividades urbanas. Las explotaciones se reducen progresivamente y el paisaje rural deja paso a una mezcolanza de usos, con una evidente pérdida de calidad. Este proceso rara vez es sometido a estudios de impacto ambiental y la intervención se reduce a una retribución económica al agricultor por el suelo que es ocupado. En este artículo proponemos una metodología que valore el impacto real que la actuación urbanística tiene tanto sobre la explotación como sobre el suelo agrario que se pierde obligando a compensar económica y territorialmente al agricultor.

Multifuncionalidad rural y percepción social en el País Vasco: un reconocimiento pendiente

[ES] Los planes de desarrollo rural del País Vasco se apoyan en gran medida en sus potencialidades naturales, paisajísticas y productivas dirigidas a un urbano que vive en la proximidad. La apreciación de la calidad del entorno rural por parte del ciudadano, por tanto, es fundamental para el progreso de las zonas rurales y supone implícitamente el reconocimiento de la multifuncionalidad de este medio. El urbano, sin embargo, aunque aprecia el entorno natural de los espacios rurales desconoce la función del agricultor en la conservación de este medio siendo la productiva la única aportación que liga a su actividad. El desarrollo rural ha de pasar por el reconocimiento social y para ello es necesario informar y educar al ciudadano.
