La influencia de la programación deportiva en el desarrollo histórico de TVE durante el monopolio de la televisión pública (1956-1988)
La relación de necesidad mutua entre la televisión española y el deporte no es un fenómeno nuevo. La mayor parte de los rasgos de la unión entre la televisión y el deporte se gestaron desde los orígenes del propio medio. Este artículo pretende analizar en profundidad las características de la programación deportiva de TVE en el período del monopolio de la televisión pública (1956-1988) para, de este modo, determinar la influencia que tuvieron estos contenidos en el desarrollo histórico de la televisión. Además, el análisis detallado de este caso permite obtener algunas respuestas ante la situación que vive en la actualidad el medio en España y, demostrar también, que el estrecho vínculo entre la televisión y el deporte no es consecuencia del establecimiento de un sistema televisivo comercial
El eterno problema del fútbol televisado en España: una perspectiva histórica de la lucha por los derechos de retransmisión de la Liga de Fútbol Profesional (LFP).
Durante los últimos 20 años hemos asistido a una dura lucha por los derechos de retransmisión de la Liga de fútbol entre las principales cadenas de televisión españolas. Este conflicto de alto componente económico y político ha marcado el desarrollo del medio en nuestro país así como las propuestas legislativas audiovisuales impulsadas en los últimos años. Sin embargo, esto no es un fenómeno nuevo. Desde los orígenes de la televisión, el papel del fútbol en la televisión ha sido decisivo. Este texto realiza un repaso histórico al conflicto del fútbol televisado que nos permitirá obtener importantes conclusiones sobre la situación que vivimos actualmente y nos dará claves sobre el futuro de este deporte en nuestra televisión
Evolución de las publicaciones en neurología clínica en España, Francia, Italia y Alemania en el período 2000-2009
This study analyzes the productivity and visibility of Spanish publications
in the area of clinical neurology in the period 2000-2009 and compared with those
for Italy, France and Germany. MATERIALS AND METHODS: We used the database Web of
Science. The analysis (annual and in five-year) was restricted to the citable
documents (original articles, reviews and proceedings papers). Bibliometric
indicators used were the number of publications, citations received by
publications and Hirsch's h-index. We also assessed the slope of the annual
growth rate (b), the number of publications by language and the international
collaboration. RESULTS: In the period 2000-2009 there were 46,114 publications in
neurology clinic of which 6,998 were Spanish publications (h = 75), 11,629 in
Italy (h = 101), French 9,745 (h = 102) and 20,143 in Germany (h = 124). The rate
of increase in the total number of publications in Spain (b = 15) was lower than
that observed in Italy (b = 65), Germany (b = 61) or France (b = 34). In the case
of publications in English, the growth rate was higher for Spain (b = 37) than
for France (b = 36) but lower than for Germany (b = 54) and Italy (b = 65).
CONCLUSIONS: Although the total number of publications and the observed increase
are lower in Spain compared to Italy, France or Germany, the Spanish publications
in Clinical Neurology shows good trend indicators with regard to publications in
English and international collaboration. This improvement was associated with
greater visibility as showed by the five-year analysis of citations received by
Spanish publications
Improving elevation resolution in phased-array inspections for NDT
The Phased Array Ultrasonic Technique (PAUT) offers great advantages over the conventional ultrasound technique (UT), particularly because of beam focusing, beam steering and electronic scanning capabilities. However, the 2D images obtained have usually low resolution in the direction perpendicular to the array elements, which limits the inspection quality of large components by mechanical scanning. This paper describes a novel approach to improve image quality in these situations, by combining three ultrasonic techniques: Phased Array with dynamic depth focusing in reception, Synthetic Aperture Focusing Technique (SAFT) and Phase Coherence Imaging (PCI). To be applied with conventional NDT arrays (1D and non-focused in elevation) a special mask to produce a wide beam in the movement direction was designed and analysed by simulation and experimentally. Then, the imaging algorithm is presented and validated by the inspection of test samples. The obtained images quality is comparable to that obtained with an equivalent matrix array, but using conventional NDT arrays and equipments, and implemented in real time.Fil: Brizuela, Jose David.

In vivo cranial bone strain and bite force in the agamid lizard Uromastyx geyri
In vivo bone strain data are the most direct evidence of deformation and strain regimes in the vertebrate cranium during feeding and can provide important insights into skull morphology. Strain data have been collected during feeding across a wide range of mammals; in contrast, in vivo cranial bone strain data have been collected from few sauropsid taxa. Here we present bone strain data recorded from the jugal of the herbivorous agamid lizard Uromastyx geyri along with simultaneously recorded bite force. Principal and shear strain magnitudes in Uromastyx geyri were lower than cranial bone strains recorded in Alligator mississippiensis, but higher than those reported from herbivorous mammals. Our results suggest that variations in principal strain orientations in the facial skeleton are largely due to differences in feeding behavior and bite location, whereas food type has little impact on strain orientations. Furthermore, mean principal strain orientations differ between male and female Uromastyx during feeding, potentially because of sexual dimorphism in skull morphology
Dicionário-aberto: a source of resources for the portuguese language processing
In this paper we describe how Dicionáio-Aberto, an online dictionary for the Portuguese language, is being used as the base to construct diverse resources that are relevant in the processing of the Portuguese language. We will briefly present its history, explaining how we got here. Then, we will describe the resources already available to download and use, followed by the discussion on the resources that are being currently developed
An Event Related Field Study of Rapid Grammatical Plasticity in Adult Second-Language Learners
Published: 24 January 2017The present study used magnetoencephalography (MEG) to investigate how Spanish adult learners of Basque respond to morphosyntactic violations after a short period of training on a small fragment of Basque grammar. Participants (n = 17) were exposed to violation and control phrases in three phases (pretest, training, generalization-test). In each phase participants listened to short Basque phrases and they judged whether they were correct or incorrect. During the pre-test and generalization-test, participants did not receive any feedback. During the training blocks feedback was provided after each response. We also ran two Spanish control blocks before and after training. We analyzed the event-related magnetic- field (ERF) recorded in response to a critical word during all three phases. In the pretest, classification was below chance and we found no electrophysiological differences between violation and control stimuli. Then participants were explicitly taught a Basque grammar rule. From the first training block participants were able to correctly classify control and violation stimuli and an evoked violation response was present. Although the timing of the electrophysiological responses matched participants' L1 effect, the effect size was smaller for L2 and the topographical distribution differed from the L1. While the L1 effect was bilaterally distributed on the auditory sensors, the L2 effect was present at right frontal sensors. During training blocks two and three, the violation-control effect size increased and the topography evolved to a more L1-like pattern. Moreover, this pattern was maintained in the generalization test. We conclude that rapid changes in neuronal responses can be observed in adult learners of a simple morphosyntactic rule, and that native-like responses can be achieved at least in small fragments of second language.Support for this project was provided to DD by Spanish Ministry of Science and Innovation (MICINN) under the program “Plan Nacional” (grant reference PSI 2011-24802) and to AB by the Basque Government (Eusko Jaurlaritza) under the program “Ikertzaile ez doktoreen doktoretza-aurreko formakuntza-programa” (grant reference PRE_2015_2_0208)
Continuity, change, and geographical differences in Spain's firewood consumption: A new estimation (1860-2010)
Although firewood was the main energy source until recently in most parts of the world, our understanding of its consumption levels is still quite limited, even in regard to recent periods. The powerful impact of fossil energy carriers and their major effects on global ecology, economy and society have led us to underestimate the role firewood has continued to play during the energy transition. This article offers a new reconstruction of long-ter m firewood consumption in Spain, taking into consideration variables related to supply and demand, which are then used to reconstruct the production, appropriation and energy uses of firewood biomass. This new series distinguishes also between the origins (forest or crop firewood), and between different regional behaviors. The main findings indicate that total and per-inhabitant consumption has been greater than traditionally assumed; that there was major regional divergence, with consumption varying significantly from one area to another; that the decline in firewood consumption was gradual and later than previously thought; and that it increased or declined over time in a non-linear fashion. Moreover, the traditionally neglected estimation of the role of woody crops was found to be very significant in this process, as it represented between 20% and 70% of total consumption for the whole data series
