Transformational Leadership, Task-Involving Climate, and Their Implications in Male Junior Soccer Players: A Multilevel Approach

Despite the well-known positive consequences of transformational coaches in sport, there is still little research exploring the mechanisms through which coaches’ transformational leadership exerts its impact on athletes. Multilevel SEM was used to examine the relationship between coaches’ transformational leadership style, a task-involving climate, and leadership effectiveness outcome criteria (i.e., players’ extra effort, coach effectiveness, and satisfaction with their coach), separately estimating between and within effects. A representative sample of 625 Spanish male soccer players ranging from 16 to 18 years old and nested in 50 teams completed a questionnaire package tapping the variables of interest. Results confirmed that at the team level, team perceptions of transformational leadership positively predicted teams’ perceptions of task climate, which in turn positively predicted the three outcome criteria. At the individual level, players’ perceptions of transformational leadership positively predicted teams’ perceptions of task climate, which in turn positively predicted teams’ extra effort and coach effectiveness. Mediation effects appeared at the team level for all the outcome criteria, and at the individual only for extra effort. Transformational leadership is recommended to enhance task climate, in order to increase players’ extra effort, their perceptions of the effectiveness of their coach, and their satisfaction with his/her leadership style

Virtudes de imperio, desventuras de emperador. El diálogo neoestoico entre Justo Lipsio y Francisco de Quevedo

En el presente artículo analizo la configuración del lenguaje estoico en la modernidad temprana, particularmente desarrollo su origen, recepción y crítica en la España del Barroco. Para articular mi argumentación divido mi exposición en cuatro partes. La primera parte indica las razones de la rehabilitación del estoicismo durante el Barroco. La segunda parte señala la recepción de la obra de Justo Lipsio en la España de los Austrias. Posteriormente, se estudia la configuración del estoicismo imperial en la obra de Francisco de Quevedo y la recuperación de la obra de Séneca durante el siglo XVII. Por último, se muestra el proceso de interpretación cristiana de algunas obras estoicas por parte de Quevedo. La conclusión a la que se llegó es que el estoicismo no sólo sirvió como el código moral que articuló la base psicológica de la ideología imperial hispánica, sino que se muestra cómo el lenguaje neoestoico permitió configurar gran parte de lenguaje moral de la modernida

En este texto se analizan varias cuestiones suscitadas en torno a la obra de Walter Mignolo, principalmente el análisis de las condiciones que debe cumplir una teoría crítica decolonial. Para ello, en la primera parte se analizan los presupuestos epistemoThis paper examines various issues raised by the work of Walter Mignolo, namely the analysis of the prerequisites of a critical theory of post-colonialism. Therefore, in the first part analyzes the epistemological premises of Mignolo's theoretical task,

Estilos de Liderazgo en la Selección Española de Taekwondo

Interest is growing in conducting research on the role of coaches as agents of influence. Within the context of sport, transactional and transformational leadership styles (Bass, 1985) have not been explored very often. This study extends previous research within this context, specifically in high performance taekwondo. The purpose of this study was to examine leadership behaviours in the Spanish National Taekwondo Team (N = 34, M age = 21 + 3.62 years of age) and explore whether transformational leadership increased the impact of transactional leadership on the athlete's extra effort and the perceived effectiveness of and satisfaction with their coach (outcome variables). The results confirmed the positive effects of transactional and transformational styles on the taekwondo players' result variables. Furthermore, the positive impact of transformational leadership augmented the effects of transactional leadership

Temas de investigación sobre aspectos psicosociales del deporte a través de la base de datos PSYCINFO (1887-2001)

En el presente trabajo se analiza el interés y representatividad de los temas de investigación sobre los aspectos psicosociales del deporte, así como las principales revistas científicas en los que se publican. Se ha realizado un análisisbibliométrico de la base de datos PsycINFO con un periodo que abarca desde 1887 hasta octubre de 2001. Los resultados informan de un gran interés por la investigación psicosocial en el ámbito de la psicología del deporte, así como de unincremento constante en el número de trabajos publicados. Entre los temas psicosociales más estudiados destacan los centrados en la participación deportiva, la motivación, el género y sexo, las emociones, los grupos y las actitudes. Más del 60% de los trabajos publicados en las principales revistas científicas del ámbito de la psicología del deporte, versan sobre aspectos psicosociales del deporte, aunque algunos de ellos sean de interés en otros ámbitos de la psicología.This study analyzes the interest and representivity of research topics on the psychosocial aspects of sport and also the most important specialized journal in which these works are published. A bibliometric analysis using the PsycINFO data from 1887 to October 2001 has been conducted. The results show that psychosocial aspects are highly represented in the sport psychology domain, and that the number of articles published is constantly increasing. The psychosocial aspects most often studied are sport participation, motivation, gender and sex, emotions, groups and attitudes. More than 60% of the articles published in the most important specialized journal in sport psychology are on the psychosocial aspects of the sport, although some of them may be of interest to other domains of psychology

Parallel 3-D marine controlled-source electromagnetic modelling using high-order tetrahedral Nédélec elements

We present a parallel and high-order Nédélec finite element solution for the marine controlled-source electromagnetic (CSEM) forward problem in 3-D media with isotropic conductivity. Our parallel Python code is implemented on unstructured tetrahedral meshes, which support multiple-scale structures and bathymetry for general marine 3-D CSEM modelling applications. Based on a primary/secondary field approach, we solve the diffusive form of Maxwell’s equations in the low-frequency domain. We investigate the accuracy and performance advantages of our new high-order algorithm against a low-order implementation proposed in our previous work. The numerical precision of our high-order method has been successfully verified by comparisons against previously published results that are relevant in terms of scale and geological properties. A convergence study confirms that high-order polynomials offer a better trade-off between accuracy and computation time. However, the optimum choice of the polynomial order depends on both the input model and the required accuracy as revealed by our tests. Also, we extend our adaptive-meshing strategy to high-order tetrahedral elements. Using adapted meshes to both physical parameters and high-order schemes, we are able to achieve a significant reduction in computational cost without sacrificing accuracy in the modelling. Furthermore, we demonstrate the excellent performance and quasi-linear scaling of our implementation in a state-of-the-art high-performance computing architecture.This project has received funding from the European Union's Horizon 2020 programme under the Marie Sklodowska-Curie grant agreement No. 777778.
