Análisis bibliométrico sobre la relación entre factores personales y profesionales en el baloncesto femenino

[ES] Tradicionalmente, las investigaciones realizadas desde la psicología del deporte se interesan por variables personales que optimizan el rendimiento. No obstante, es sabido que el contexto deportivo influye tanto en el rendimiento profesional como personal. El objeto de esta investigación fue revisar la bibliografía publicada en relación a la influencia bidireccional de variables personales, contextuales y de rendimiento, en la faceta profesional y personal de jugadoras de baloncesto profesional. Los resultados ponen de manifiesto que la práctica totalidad de las investigaciones revisadas se interesan por la influencia de las variables psicológicas en el rendimiento de la deportista. Únicamente hemos encontrado dos estudios que aluden a la influencia del contexto como factor que afecta tanto en la faceta profesional como personal de las deportistas. [EN] Traditionally, sport psychology research is interested in personal variables that optimize the performance. Nevertheless, it is known that the sports context influences as much the professional performance as personal. The aim of this research is to review all published bibliography on mutual relations between personal, contextual and performance variables over both the personal and the professional life of elite women basketball playersl. Results show that practically all reviewed research has been interested in the influence of psychological variables on the sport performance. Only we have found two studies that allude to the influence of the context as factor that affects so much the professional as personal facet of the sportswomen.

Understanding the zooplankton ammonium excretion: from biogeochemical implications to intracellular regulatory mechanisms

[EN] This thesis focuses on the zooplankton NH4+ regeneration that supports about the 80% of the phytoplankton requirements. In its more oceanographic facet, it elucidates the control that the mesozooplankton community exerts on the primary productivity in the northern Benguela, and models the N-fluxes from zooplankton NH4+ excretion. At the physiological level, it examines the relationship between the NH4+ excretion and its associated biochemistry. Assuming the substrate availability as the critical factor in regulating the velocity of NH4+ production, a bisubstrate model was developed to predict its actual rate in zooplankton. Overall, this research provides knowledge about the implications of zooplankton NH4+ excretion on the biogeochemical cycles, and introduces new insights into the study of this process from enzymatic measurements.
