¿Tradición o renovación? : un estudio a través del cante flamenco de Antonio Chacón y Enrique Morente

La investigación que hemos realizado trata de dar respuesta a la cuestión de si existe tradición o renovación en la evolución del cante flamenco. Para ello nos servimos de la realización de transcripciones y análisis comparados de una selección de cantes de Antonio Chacón y los mismos de Enrique Morente. Medio siglo aproximadamente separan las grabaciones de uno y otro, lo suficiente para estudiar las permanencias y los cambios que puedan existir en los parámetros que identifican el Cante flamenco.The research we have done is to answer the question of whether there is tradition or renovation in the evolution of Flamenco. To support our research we used transcripts and comparative ana lysis of a selection of Flamenco songs by Antonio Chacón and Enrique Morente. Approximately half a century separate the recordings of both musicians, which is a large enough gap of time to study the permanence and changes that may exist in the parameters that identify Flamenco

La categoría teatral del espacio en Aristófanes: Los prólogos como ejemplo

The paper does some observations about the dramatic element of space in Aristophanes, always from the point of view of the perfomance. Several aspects about the theatrical meaning of space, the difficulties of his study in the ancient Greek comedy and the diverse theories about it are discussed. Finally it comes to the conclusion that the aristophanic space, always delimited by the dialogue, is a very important dramatic instrument and it tries to show some examples of his aspects in the prologues.Partiendo de una línea de análisis del teatro clásico como espectáculo, el artículo hace una reflexión sobre la utilización que Aristófanes hace en su obra de la categoría teatral del espacio. Para ello revisa algunas características del espacio teatral, la dificultad para su estudio en la comedia antigua y las distintas teorías sobre el espacio en la escena aristofánica. Como conclusión justifica su valor como elemento dramático ligado al diálogo y define las características de su configuración a través de algunos ejemplos de los prólogos

Na+-dependent NO3- uptake in leaf cells of the seagrass Posidonia oceanica (L.) Delile

Posidonia oceanica (L.) Delile is an endemic Mediterranean seagrass of recognized ecological significance and, as other seagrasses, this species has secondarily adapted to live in the marine environment. In this alkaline medium with a high Na+ concentration (0.5 M), the high inwardly directed electrochemical potential gradient for sodium is used in the seagrass Zostera marina to energize the uptake of nitrate1 and phosphate that usually occur at concentration below 10 µM. Here we summarize several evidences for the operation of a sodium-dependent high-affinity nitrate transport system at the plasma membrane of the mesophyll leaf cells of P. oceanica. Leaf cells of P. oceanica possess a H+-ATPase as a primary pump, exhibit a plasma membrane potential (Em) of -174 ± 10 mV and show reduced Na+ permeability. The addition of micromolar nitrate concentrations induces membrane depolarizations that show saturation kinetics. Curve fitting of the values renders a semisaturation constant (Km) of 21.3 ± 6.6 μM and a maximum depolarization (Dmax) of 7 ± 1 mV. In dark conditions, Dmax decreases by fifty percent but no significant effect is observed on the Km value. On the other hand, nitrate induced depolarizations show sodium dependence. The depolarizations induced by 100 µM NO3- in media containing increasing Na+ concentrations (from 0 to 250 mM) show saturation kinetics, rendering a Km value of 16 ± 5 mM Na+. Moreover, the depolarization induced by 100 µM NO3- is accompanied by a simultaneous increase of cytosolic sodium, measured by Na+-sensitive microelectrodes, of 0.4 ± 0.2 mM above the resting cytosolic sodium concentration (17 ± 2 mM). Finally, nitrate uptake rates, measured in depletion experiments, decreases by 50% and 80% in dark conditions and in the absence of Na+, respectively, compared with control conditions (0.5 M Na+ and light). All together, these results strongly suggest that NO3- uptake in P. oceanica leaf cells is mediated by a high-affinity nitrate carrier that uses Na+ as the driving ion. 1 Rubio et al. (2005). J. Exp.

Seasonal dynamic factor analysis and bootstrap inference : application to electricity market forecasting

Year-ahead forecasting of electricity prices is an important issue in the current context of electricity markets. Nevertheless, only one-day-ahead forecasting is commonly tackled up in previous published works. Moreover, methodology developed for the short-term does not work properly for long-term forecasting. In this paper we provide a seasonal extension of the Non-Stationary Dynamic Factor Analysis, to deal with the interesting problem (both from the economic and engineering point of view) of long term forecasting of electricity prices. Seasonal Dynamic Factor Analysis (SeaDFA) allows to deal with dimensionality reduction in vectors of time series, in such a way that extracts common and specific components. Furthermore, common factors are able to capture not only regular dynamics (stationary or not) but also seasonal one, by means of common factors following a multiplicative seasonal VARIMA(p,d,q)×(P,D,Q)s model. Besides, a bootstrap procedure is proposed to be able to make inference on all the parameters involved in the model. A bootstrap scheme developed for forecasting includes uncertainty due to parameter estimation, allowing to enhance the coverage of forecast confidence intervals. Concerning the innovative and challenging application provided, bootstrap procedure developed allows to calculate not only point forecasts but also forecasting intervals for electricity prices

Women’s disengagement from legal proceedings for intimate partner violence in southern Spain: Variables related to legal proceedings

This article studies the relationship between a set of variables related to the legal process and women’s disengagement from legal proceedings against their (ex)partners in Southern Spain. A total of 345 women answered a questionnaire. Results evidenced that request for a protection order (PO), granting such PO, imprisonment of the offender, and women’s perception of who decided during the process were significantly related to disengagement (medium effect size). In addition, a logistic regression model was developed to predict disengagement with two variables: granting a PO and women’s perception of who decided. Results are interpreted in terms of the necessity that the judicial system gives support, protects, and provides women with opportunities to participate in the recovery process.Junta de Andalucía 1071/0453Ministerio de Educación, Cultura y Deporte (España) FPU15/0037

La participación educativa de la mujer en su proceso de envejecimiento: retos y posibilidades

[Resumen] El estudio del proceso de envejecimiento desde parámetros educativos y/o pedagógicos es una realidad en creciente desarrollo. En este marco cobra cada día más fuerza la experiencia educativa de muchas mujeres mayores para las que la educación (formal o no formal) encierra un doble significado de reto, en ocasiones dificultoso, y de satisfacción personal. Partiendo de una experiencia concreta de intervención educativa e investigación llevada a cabo con mujeres mayores, el objetivo de este trabajo es reflexionar sobre la incidencia de la participación educativa en la vida y el proceso de envejecimiento de la mujer, sobre su percepción del aprendizaje y sobre las condiciones y elementos que contribuyen a optimizar los procesos instruccionales en los que participan[Abstract] The study of aging process from educative and/or pedagogic parameters is a reality in growing development. In this framework, a double meaning educative experience (formal and non formal) becomes more and more important for elderly women. These meanings are challenge, sometimes difficult, and personal satisfaction. We start from a concrete experience in educative intervention and research on elderly women. The main objective is to reflect on how the educative participation can affect women's life and aging process, as well as their leaming perception. A secondary objective is to analyse conditions and elements that contribute to optimise the educational process in which they take part

Equity pricing in the mining sector: evidence from NYSE and LSE

The study examines the Capital Asset Pricing Model (CAPM) for the mining sector using weekly stock returns from 27 companies traded on the New York Stock Exchange (NYSE) or on the London Stock Exchange (LSE) for the period of December 2008 to December 2010. The results support the use of the CAPM for the allocation of risk to companies. Most companies involved in precious metals (particularly gold), which have a beta value less than unity (Table 1), have been actuated as shelter values during the financial crisis. Values of R2 do not shown very explanatory power of fitted models (R2 < 70 %). Estimated coefficients beta are not sufficient to determine the expected returns on securities but the results of the tests conducted on sample data for the period analysed do not appear to clearly reject the CAP

Use of Alternative Wood for the Ageing of Brandy de Jerez

The use of alternative types of wood has arisen for the aging of the Brandy de Jerez, on a pilot plant level. In particular, besides the use of American oak, two more types of oak have been studied, French oak and Spanish oak, allowed by the Technical File for the ID Brandy de Jerez, and chestnut, which, though it is not officially allowed, is a type of wood which had been traditionally used in the area for the aging of wines and distillates. All of them have been studied with different toasting levels: Intense toasting and medium toasting. The study of the total phenolic composition (TPI), chromatic characteristics, organic acids, and sensory analysis have proven that chestnut leads to distillates with a higher amount of phenolic compounds and coloring intensity than oak. This behavior is the opposite as regards the toasting of the wood. Among the different types of oak, Spanish oak produces aged distillates with a higher phenolic composition and a higher color intensity. Regarding tasting, the best-assessed samples were those aged with chestnut, French oak, and American oak, and the assessors preferred those who had used a medium toasting level to those with an intense leve
