Follow your nose: chemical communication throughout the European eel (Anguilla anguilla, L.) life-cycle

European eels are important in both scientific and economic terms. Unfortunately, current populations are becoming increasingly endangered and urgentmanagement is needed. Several aspects of eel biology, together with their highly developed sense of smell, suggest that chemical communication could be involved at key stages of their life-history. Thus, advances in this area could generate novel tools for stock management

Petrology and geochemistry of the Old Edifice of Santa Luzia island (Cape Verde Archipelago)

Santa Luzia island is essentially formed by erosional remnants of, at least, one volcanic edifice: the Old Edifice. The remains of this edifice are now a NW-SE trending mountain range. It is a fisural edifice that follows this trend and is formed by hundreds of meters of aa-type lava flows crosscut by dikes. Lithologic compositions are basic and ultrabasic (picrobasalts, basanites, basalts and trachybasalts), intermediate (trachyandesites) and felsic (trachytes and phonolites). The main process generating these compositional differences is fractional crystallizationLa isla de Santa Luzia está formada esencialmente por los restos erosivos de, al menos, un edificio volcánico: el Edificio Antiguo. Los restos de este edificio forman en la actualidad una alineación montañosa de dirección NWSE. Se trata de un edificio fisural alineado en la mencionada dirección formado por centenares de metros de coladas de lava de tipo aa y por diques que lo atraviesan. Las rocas que lo forman son básicas y ultrabásicas (basaltos picríticos, basanitas, basaltos y traquibasaltos), intermedias (traquiandesitas) y félsicas (traquitas y fonolitas). El principal proceso generador de estas diferencias composicionales es la cristalización fraccionad

Effects of educational mismatch on private returns to education: An analysis of the Spanish case (1995-2006)

This study examines the effects of educational mismatch on wages in the Spanish labour market since the mid-nineties. First we study the evolution of returns to education and then we estimate returns to education in terms of the match between the worker’s schooling and the job requirements. The results indicate that returns to education have declined since the mid-nineties. One also finds that the return associated with the job’s required education is greater than that corresponding to the worker’s actual schooling, and that the return on an additional year of attained education is positive b ut less than that of an additional year of required education. From a policy perspective, the existence of educational mismatch points to inefficiencies in the allocation of the educational resources. Investment on education can positively contribute to alleviate the unemployment problem in Spain, but taken into account the existence of educational mismatch it also becomes necessary to introduce structural reforms in order to adapt the job structure to a model of production based on knowledge so that the more highly qualified workers can find a job that corresponds to their educational level.Spanish Ministry of Science and Innovation (Fun-damental Research Projects ECO2009-13864-C03-01 and ECO2009-13864-C03-02)

Bioimpedance real-time charazterization of neointimal tissue inside stents

It is hereby presented a new approach to monitor restenosis in arteries fitted with a stent during an angioplasty. The growth of neointimal tissue is followed up by measuring its bioimpedance with Electrical Impedance Spectroscopy (EIS). Besides, a mathematical model is derived to analytically describe the neointima’s histological composition from its bioimpedance. The model is validated by finite-element analysis (FEA) with COMSOL Multiphysics®. Satisfactory correlation between the analytical model and the FEA simulation is achieved for most of the characterization range, detecting some deviations introduced by the thin "double layer" that separates the neointima and the blood. It is shown how to apply conformal transformations to obtain bioimpedance models for stack-layered tissues over coplanar electrodes. Particularly, this is applied to characterize the neointima in real-time. This technique is either suitable as a main mechanism of restenosis follow-up or it can be combined with proposed blood-pressure-measuring intelligent stents to auto-calibrate the sensibility loss caused by the adherence of the tissue on the micro-electro-mechanical sensors (MEMS).Ministerio de Economía, Industria y Competitividad (Spain): projects TEC2013-46242-C3-1-PMinisterio de Economía, Industria y Competitividad (Spain): projects TEC2013-46242-C3-2-

Efectos del desajuste educativo sobre el rendimiento privado de la educación: un análisis para el caso español (1995-2006)

En este estudio se analizan los efectos del desajuste educativo sobre los salarios en el mercado de trabajo español desde mediados de los años noventa. En primer lugar se estudia la evolución de los rendimientos educativos mediante la estimación de ecuaciones mincerianas (Mincer, 1974), estimando a continuación el rendimiento educativo en función del grado de adecuación entre la escolaridad del trabajador y los requerimientos formativos de su puesto de trabajo a partir de las especificaciones ORU (Over-Required-Undereducated) propuestas por Duncan y Hoffman (1981). Los resultados obtenidos indican que la rentabilidad de la educación ha disminuido desde mediados de los años noventa. Se observa asimismo que el rendimiento asociado a la escolaridad requerida en el empleo es mayor al que corresponde a la educación efectiva del trabajador, mientras que el rendimiento de un año adicional de sobreeducación es positivo pero inferior a la rentabilidad de un año adicional de educación requerida.Ministerio de Ciencia e Innovación.

Gender wage differentials and educational mismatch: an application to the Spanish case

This article aims to analyse gender wage differentials in Spain by taking into account the levels of educational attainment and by studying whether the educa-tional mismatch affects the gender wage gap. Focusing on returns to education, evidence is found on the existence of educational mismatch and on its contribu-tion to determine wages, with women suffering greater wage penalties that are associated with educational mismatch. Furthermore, although the gender wage gap is lower for individuals with low educational levels, we find that the part of this gap due to differences in returns is greater in this group. On the contrary, the gender gap is greater among highly-educated workers, but in this case most of the wage differentials are due to differences in productive characteristics. In any case, our results suggest that gender wage discrimination tends to be greater for those workers who show educational mismatch.Spanish Ministry of Science and Innovation (Fundamental Research Projects ECO2009-13864-C03-01 and ECO2009-13864-C03-02

Real-time electrical bioimpedance characterization of neointimal tissue for stent applications

To follow up the restenosis in arteries stented during an angioplasty is an important current clinical problem. A new approach to monitor the growth of neointimal tissue inside the stent is proposed on the basis of electrical impedance spectroscopy (EIS) sensors and the oscillation-based test (OBT) circuit technique. A mathematical model was developed to analytically describe the histological composition of the neointima, employing its conductivity and permittivity data. The bioimpedance model was validated against a finite element analysis (FEA) using COMSOL Multiphysics software. A satisfactory correlation between the analytical model and FEA simulation was achieved in most cases, detecting some deviations introduced by the thin “double layer” that separates the neointima and the blood. It is hereby shown how to apply conformal transformations to obtain bioimpedance electrical models for stack-layered tissues over coplanar electrodes. Particularly, this can be applied to characterize the neointima in real-time. This technique is either suitable as a main mechanism for restenosis follow-up or it can be combined with proposed intelligent stents for blood pressure measurements to auto-calibrate the sensibility loss caused by the adherence of the tissue on the micro-electro-mechanical sensors (MEMSs).This work was carried out in collaboration with the Cardiology Department of the UHMV Hospital, Santander (Spain) and was funded by the Spanish Government’s “Ministerio de Economía, Industria y Competitividad” under the joint projects TEC2013-46242-C3-1-P and TEC2013-46242-C3, co-financed with FEDER
