Sobre las palabras "vascones" y "euskera"

Actualmente los términos "vasco" y "euskera" se consideran sinónimos, pero antiguamente no eran equivalentes, además no están relacionadas en su etimología. "Basco" o "vasco" no proviene palabra del euskera aunque hay autores que consideran que deriva de "baso-ko" (de la montaña). Para el autor proviene de la forma indoeuropea "bhar-" que podría significar altos o montañeses y sería la tribu de los "ba(r)´scunes". La etimología de "eusk-" es más complicada, cree que deriva de otra tribu distinta, los "Ausci" en Aquitani

Price-based capital account regulations: the Colombian experience

The Chilean experience with price-based capital account regulations (i.e., deposits or reserve requirements on capital inflows) has been subject to extensive discussion in the recent literature. This paper presents evidence on the effectiveness of similar regulations in Colombia since September 1993, when traditional exchange controls were replaced by price-based regulations. It is important to emphasize that the Tobin tax equivalent of such regulations in Colombia has been quite high (13.6% and 6.4% tax for 12 and 36 months loans, respectively, in 1994-1998), and, as in Chile, it is certainly much higher than the rates suggested for an international Tobin tax. The econometric evidence presented indicates that these regulations have been effective in Colombia, both in terms of reducing the volume of flows and in improving the term structure of external borrowing. This indicates that price-based regulations give the authorities some room for maneuver to adopt restrictive monetary policies during international capital market booms. They have also been effective in improving the debt profile of the country, a crucial determinant of macroeconomic risks in the face of busts in the international capital market.

Precipitation in the Mediterranean basin as seen from the 2000-2010 TRMM-3B42-v6 database

Sarrand, B. et al.Trabajo presentado en la EGU General Assemby 2012, celebrada del 22 al 27 de septiembre de 2012 en Viena (Austria)This work presents a detailed analysis of 11 yrs of the version 6 of the TRMM-3B42 multi-sensor precipitation product (3-h and 0.25° resolution) from March 2000 to February 2011 over the whole Mediterranean basin and surrounding areas including the Black Sea (25°N-50°N, 10°W-43°E). We first discuss some issues in the data set regarding spatial and temporal discontinuities in coastal areas, and further illustrate a critical underestimation of light rains at latitudes higher than 36-37° that somewhat improves from 2007 on and is associated to the absence of coverage by the Precipitation Radar. North of the radar field of view, it seems that the marine coastal band is subject to a significant under detection of precipitation, whereas, on the opposite, the terrestrial coastal band south of 35°N in North Africa and the Near East shows unrealistic over detection of precipitation. We then evaluate the product against rain gauges with a focus on the western Mediterranean basin and the Adriatic. Our reference rain gauge data set includes about 1 million daily rain reports from more than 260 Mediterranean surface stations from Croatia, France, Italy, Malta, Spain (including 2 stations on the northern coast of Africa) and Tunisia, and from 9 additional non-Mediterranean stations from a flat region in France. It includes stations from almost 20 small Mediterranean islands. The comparison shows a significant correlation between TRMM-3B42v6 and rain gauges but with an overall tendency to underestimation. The average ratio of daily rates between surface stations and TRMM product is ~0.63 with significant regional variations, Corsica showing the poorest results and Spain the best. Over the Mediterranean stations considered, the average rate of success on the occurrence of precipitation (~0.75) is enhanced by the high proportion of dry days in the Mediterranean climate (~4 over 5 on average in the rain gauge data set) and drops off when only days with precipitation recorded at surface stations are considered. Averaging fallout at monthly and annual time scales somewhat improves the comparison to rain gauges. We find that results are better in summer and likely more generally in unstable conditions, as illustrated by a subset of data composed of days with high African dust load over the basin. Using a few TRMM pixels that cover 3 or even 5 surface stations, we further illustrate how the small scale heterogeneity of precipitation is a limitation in the comparison between the integrated view of precipitation from space and the local surface measurements. Finally we integrate the variability of the rainfall geographical distribution at seasonal and annual scales over 5 sub-basins (western and eastern Mediterranean, Adriatic, Aegean, and Black Sea). An increasing trend in annual precipitation in the Mediterranean basin is observed over the decade that is also found at the global scale and appears related to the improving performance of the product with time regarding the detection of light rains, especially over Europe and the Mediterranean. Finally we compare the TRMM-3B42v6 precipitation budget over the basin with comparable budgets from ERA-Interim, HOAPS and CMAP data setsPeer Reviewe

Are Sunscreen a New Environmental Risk Associated with Coastal Tourism?

The world coastal-zone population and coastal tourism are expected to grow during this century. Associated with that, there will be an increase in the use of sunscreens and cosmetics with UV-filters in their formulation, which will make coastal regions worldwide susceptible to the impact of these cosmetics. Recent investigations indicate that organic and inorganic UV-filters, as well as many other components that are constituents of the sunscreens, reach the marine environment - directly as a consequence of water recreational activities and/or indirectly from wastewater treatment plants (WWTP) effluents. Toxicity of organic and inorganic UV filters has been demonstrated in aquatic organism. UV-filters inhibit growth in marine phytoplankton and tend to bioaccumulate in the food webs. These findings together with coastal tourism data records highlight the potential risk that the increasing use of these cosmetics would have in coastal marine areas. Nevertheless, future investigations into distribution, residence time, aging, partitioning and speciation of their main components and by-products in the water column, persistence, accumulation and toxicity in the trophic chain, are needed to understand the magnitude and real impact of these emerging pollutants in the marine system. © 2015 Elsevier Ltd.D.S.-Q. was supported by the JAE-predoc program of the Spanish National Research Council (CSIC)Peer Reviewe
