Grado de satisfacción y preferencias técnico-tácticas de jugadores de balonmano en etapas de formación según el sexo de los jugadores

The aims of this study are: a) analyse the technical and tactical preferences of handball players in both training and competition, differentiating between genders; b) learn which are the preferred actions of handball players, differentiating between genders; c) differentiate the numerical situations of play preferred by the players according to gender of the player. A selective study was carried out on players in the U-14 and U-16 categories who participated in Spain's 2012 Handball Championship for territorial teams (n = 1015), dividing them into two groups: a) male and b) female. The methodology used was the "Handball Player Satisfaction and Preferences Questionnaire". The most important results showed that: a) the technical-tactical action preferred for both groups is to launch the ball; b) the game phase preferred for both groups is attack; c) girls show a greater preference for defence than boys; d) some defensive actions cause great satisfaction in both groups, while some feel themselves conditioned by what they believe their coaches like and ask for. These data can be used to optimise the process of teaching and learning in boys' and girls' handball, understanding that their preferences are not the same.Los objetivos del presente estudio son: a) analizar las preferencias técnico-tácticas de jugadores de balonmano, tanto en entrenamiento como en competición, diferenciando entre sexos; b) Saber cuáles son las acciones preferidas de los jugadores de balonmano diferenciando entre sexos; y c) diferenciar las situaciones de igualdad o desigualdad numérica de juego preferidas por los jugadores según el sexo del jugador. Se desarrolló un estudio de carácter  selectivo sobre los jugadores de categoría infantil y cadete que participaron en el Campeonato de España de Balonmano por selecciones territoriales de 2012 (n=1015), diferenciando dos grupos: a) masculino y b) femenino. Se utilizó como instrumento el “Cuestionario de Satisfacción y Preferencias en Jugadores de Balonmano”. Los resultados más importantes mostraron que: a) La acción técnico-táctica favorita en ambos grupos es la de lanzar; b) La fase del juego favorita en ambos grupos es la de atacar; c) las chicas muestran una mayor preferencia por la defensa que los chicos; y d) Ciertas acciones defensivas ocasionan una gran satisfacción en ambos grupos, algo que se cree condicionado por lo que creen que les gusta y que piden sus entrenadores. Estos datos pueden servir para optimizar el proceso de enseñanza-aprendizaje del balonmano en chicos y chicas, entendiendo que sus preferencias no son las mismas

Discretion in the application of the goodwill impairment test in European banks

In the absence of amortization of goodwill, the purpose of this study is to identify whether the impairment test was applied uniformly between 2005 and 2015 at the 45 biggest banks in Europe, during the first decade of IFRS application. Likewise, an attempt has been made to verify whether such application has been insufficient and late. Through a significant sample, statistical tools already widely used in other studies have been applied to contrast the behavior of entities. The results obtained show that impairment policies have been applied unevenly in each of the countries. These conclusions could support the return to a valuation pattern that takes into account the systematic amortization of goodwill, apart from its impairment. This paper reveals how impairment in European banks has been recognized during a crucial period of time that includes a major financial crisis. The study suggests a discretionary and opportunistic implementation of accounting regulations which does not reveal the economic conditions inherent to the financial activity of the leading European banks, making comparability difficult and, ultimately, making the financial information less relevant.Discrecionalidad en la aplicación del test de deterioro del fondo de comercio en la banca europea Dada la ausencia de amortización del fondo de comercio, el objetivo de esta investigación se concreta en identificar si el test de deterioro, entre los ejercicios 2005 y 2015, primera década de aplicación de las NIIF, ha sido aplicado de manera homogénea y coherente por los 45 mayores bancos europeos. Asimismo, se ha tratado de comprobar si dicha aplicación ha podido ser insuficiente y tardía. A través de una muestra significativa, se han aplicado herramientas estadísticas ampliamente utilizadas en otros estudios, para contrastar el comportamiento de las entidades. Los resultados obtenidos evidencian que las políticas de deterioro han sido aplicadas de manera desigual en cada país. Estas conclusiones podrían soportar la vuelta a un patrón de valoración que considerase la amortización sistemática del fondo de comercio, aparte de su deterioro. El trabajo muestra la aplicación del deterioro en los bancos europeos, durante un periodo temporal de especial importancia, puesto que incluye los años de crisis financiera. El estudio sugiere una implementación de la normativa contable que puede ser calificada de discrecional y oportunista en la contabilización del fondo de comercio

Polytopic bis(oxazoline)-based ligands for recoverable catalytic systems applied to the enantioselective Henry reaction

Several kinds of polytopic chiral ligands (including ditopic, tritopic and tetratopic), based on the bis(oxazoline) and azabis(oxazoline) motifs, have been tested in the preparation of recoverable catalytic systems for the Henry reaction. The results obtained with the different ligands are, in general, good, but they point to the existence of a delicate balance between the coordinating ability of the ligand, the catalytic activity and the recovery of the catalyst by formation of the coordination polymer, related to the easiness to form oligomeric species in solution

Using plant-based preparations to protect common bean against halo blight disease: the potential of nettle to trigger the immune system

Halo blight disease of beans (Phaseolus vulgaris L.), caused by the bacterium Pseudomonas syringae pv. phaseolicola (Pph), is responsible for severe losses in crop production worldwide. As the current agronomic techniques used are not effective, it is necessary to search for new ones which may prevent disease in common bean. In this study, we challenged four plant-based preparations (PBPs), with no other agronomic uses, as they come from industrial waste (grapevine pomace (R-G) and hop residue (R-H)) or wild plants (Urtica dioica (U) and Equisetum sp. (E)), to be used as immune defense elicitors against Pph in common bean. After studying their inhibitory effect against Pph growth by bioassays, the two most effective PBPs (R-G and U) were applied in common bean plants. By measuring the total H2O2, lipid peroxidation, and antioxidant enzymatic activities, as well as the expression of six defense-related genes-PR1, WRKY33, MAPKK, RIN4, and PAL1-, it was observed that U-PBP application involved a signaling redox process and the overexpression of all genes, mostly PR1. First infection trials in vitro suggested that the application of U-PBP involved protection against Pph. The elicitation of bean defense with U-PBP involved a decrease in some yield parameters, but without affecting the final production. All these findings suggest a future use of U-PBP to diminish halo blight disease

Efectos de varios factores ambientales sobre las tasas de descomposición en encinares mediterráneos

Resumen de una presentación realizada en: I Simposio sobre Interacciones Planta-Suelo (ICA-CSIC, Madrid, 25-26 Febrero 2016)[ES] Los encinares son ecosistemas de gran valor que están sufriendo un proceso de decaimiento, lo que puede afectar a su capacidad para almacenar carbono. Se plantea este proyecto de tesis para estudiar el efecto del decaimiento de encinares sobre las tasas de descomposición de la hojarasca, las raíces y las herbáceas, y los factores medioambientales que la controlan. Los factores que se pretende estudiar son: la calidad de la materia en descomposición, el clima, la fotodegradación, y el efecto de diferentes conjuntos de fauna del suelo. El efecto de dichos factores sobre la descomposición se analizará a través de 4 experimentos con bolsas de descomposición. Experimento 1: Efecto del clima, de la fotodegradación y de la calidad de la hojarasca sobre las tasas de descomposición. Se ha diseñado un experimento factorial para el seguimiento de las tasas de descomposición de herbáceas y de hojas y raíces de encinas, situando bolsas en 8 encinares afectados distribuidos por el territorio peninsular español. Experimento 2: Efecto de la microfauna, la mesofauna y la macrofauna del suelo sobre los procesos de descomposición de hojarasca. Se estudiará mediante tratamientos de exclusión de fauna del suelo. Experimento 3: Efecto interactivo de la temperatura, precipitación y radiación solar sobre la descomposición de hojarasca. Se utilizarán mesocosmos para someter bolsas de hojarasca de herbáceas a dos niveles para cada uno de esos tres factores, con todas las interacciones entre ellos. Experimento 4: Contribución de diferentes procesos abióticos (fotodegradación y degradación térmica), bióticos (descomposición microbiana) así como su interacción en la descomposición de la materia orgánica. Se realizará con herbáceas bajo condiciones controladas de laboratorio. Estos experimentos permitirán describir de una manera mecanicista un proceso tan relevante para las interacciones planta-suelo como es la descomposición así como los factores medioambientales que la controlan.Peer reviewe

Association between telomere length, frailty and death in older adults.

Frailty is considered a clinical marker of functional ageing. Telomere length (TL) has been proposed as a biomarker of biological age but its role in human ageing is controversial. The main aim of the study was to evaluate the longitudinal association of TL with incident frailty and mortality in two cohorts of Spanish community–dwelling older adults. TL was determined at baseline in blood samples from older adults included in Toledo Study for Healthy Aging and ENRICA cohorts while frailty was determined by frailty phenotype (FP) at baseline and at follow-up (3.5 years). Deaths occurring during follow-up were also recorded. Associations of TL with frailty and mortality were analysed by logistic regression with progressive adjustment. Data were separately analysed in the two cohorts and in all subjects by performing a meta-analysis. TL was not different between frail and non-frail subjects. Longer telomeres were not associated with lower risk of prevalent frailty. Similarly, TL at baseline failed to predict incident frailty (OR: 1.04 [0.88–1.23]) or even the development of a new FP criterion (OR: 0.97 [0.90–1.05]) at follow-up. Lack of association was also observed when analysing the development of specific FP criteria. Finally, while frailty at baseline was significantly associated with higher risk of death at follow-up (OR: 4.08 [1.97–8.43], p < 0.001), TL did not significantly change the mortality risk (OR: 1.05 [0.94–1.16]). Results show that TL does not predict incident frailty or mortality in older adults. This suggests that TL is not a reliable biomarker of functional age.post-print660 K
