progress and happiness - however these terms may be understood in detail - as a significant and constitutive element of scientific inquiry. In this sense the question of the way in which sport really benefits people and contributes to their happiness, and under which individual and social conditions, is a scientific question. It assumes special significance when the fact is taken into account that in the field of sport science a general scepticism is shown towards those dogmas and pedagogical theses which take such an interpretation for granted in the absence of a firm empirical foundation and a critically evolved theory. Sport and Sport Science Sport and exercise, physical culture and education in sport (physical training), gymnastics and touring combined with some form of sport are-as the present report distinctly shows-all over the world among the most striking social phenom ena of today. At first sight they seem to be uncomplicated, clear and comprehensible for everybody; they stand for a type of solidarity which is independent of differences in ideological-political outlook, and sometimes exhibit an almost archaic intensity and attraction; they are supported by the active participation or at least the interest of very many people in many parts of the world and are endued with specific func tions, varying in importance, of a medical (therapeutical, prophylactic, rehabilitative), pedagogical, psychological and social character.

La necesidad sexual humana todavía se conoce como libido, es decir, el deseo de sexualidad. Está destinado a la libido tanto para dar a luz a los niños, como para tener relaciones sexuales. A lo largo de la vida de una persona, el deseo de sexualidad puede fortalecerse o debilitarse, todo depende del período en el que vive la persona, hasta la edad fértil, la edad de procrear y después de la edad fértil.

Este libro, fruto de un Proyecto de Investigación, es el resultado del trabajo de un grupo de profesores de Traducción de la Universidad de Las Palmas de Gran Canaria. Al desear encontrar el equilibrio entre docencia e investigación, el grupo se plantea una serie de preguntas y retos que los ayudan a reflexionar sobre qué hacen y cómo pueden mejorar, para llevar a cabo una pedagogía activa basada en la traducción práctica y el entendimiento empírico. En el primer capítulo se analiza la enseñanza de la traducción, señalando algunas deficiencias y la necesidad de nuevos objetivos y modelos en la formación de traductores. El segundo capítulo se centra en las teorías contemporáneas traductológicas, pues tal y como se recoge en cualquier principio pedagógico, práctica y teoría deben estar integradas. En el tercer capítulo se propone un modelo didáctico que el grupo aplica en el proceso de producción de textos. La segunda parte del libro se centra en la práctica de la traducción y se ofrecen una serie de textos generales y semi-especializados en versión original en inglés y una de las posibles variantes de la traducción al español. La intención del libro es servir de guía de estudio a los alumnos de los primeros años de traducción, sin olvidar a los autodidactas que deseen adentrarse en este campo. Si se logra despertar el interés de los lectores y que acudan luego a obras más especializadas, se habrá cumplido el propósito inicial.

Team Sports Training: The Complexity Model presents a novel approach to team sports training, examining football (soccer), rugby, field hockey, basketball, handball and futsal through the paradigm of complexity. Under a traditional prism, these sports have been analyzed using a deterministic perspective, where the constituent dimensions of the sportsmen were independently examined and treated in isolation. It was expected that the body worked as a perfect machine and, once all the components were maximized, the sportsmen improved their performance. If the same closed recipe was applied to all the players that formed part of the squad, the global team performance was expected to be enhanced. As much as these reductionistic models seem coherent, when contrasted in practice we see that the reality of team sports is far more different from the closed conditions in which they were idealized. Team sports contain variable, heterogeneous and non-linear constrains which require the development of a different logic to organize their training. During the last years, ecological psychology, the dynamical systems theory or the constraints-led approach have opened interesting fields of research from which many conceptual foundations can be applied to team sports. Based in this contemporary framework, the current book presents the study of the players and the teams as complex systems, using coordination dynamics to explain the emergence of the self-organisation episodes that characterize them. In addition, this thinking line provides the reader with the ability to apply all these innovative concepts to their practical training scenarios. Altogether, it is intended to challenge the reader to re-think their training strategy and to develop an original theory and practice of training specific to team sports.
