Unraveling Public Good Games: The Role of Priors

This paper provides experimental evidence on how players predict end game effects in a linear public good game. Our regression analysis yields a measure of the relative importance of priors and signals on subjects\' beliefs on contributions and allow us to conclude that, firstly, the weight of the signal is relatively unimportant, while priors have a large weight and, secondly, priors are the same for all periods. Hence, subjects do not expect end game effects and there is very little updating of beliefs.

Plan de Marketing Fisioterapia BE GOOD

El objetivo del presente documento es definir y presentar el Plan de Marketing asociado a una empresa basada en una propuesta empresarial. La empresa a la que se va a hacer referencia en dicho Plan es un centro fisioterapéutico que se denominará “Be Good”. La clínica fisioterapia “Be Good”, se situará en la calle “Villa de Plencia” localizada en el municipio de Getxo y nacerá con el objetivo de ofrecer un servicio de calidad dirigido a la cura y prevención de lesiones músculo-esqueléticas, afecciones respiratorias, patologías neurológicas y, en general, a la satisfacción de cualquier tipo de persona que solicite sus servicios. Aunque existan diferentes metodologías, para llevar a cabo el Plan de Marketing se ha decidido seguir el procedimiento propuesto por José María Sainz de Vicuña (2013). Por medio de la metodología seleccionada, el Plan de Marketing descrito en el presente documento tratará de mejorar la eficacia en la toma de decisiones que influyan en la empresa. Adicionalmente, se actuará de medio para el logro de los objetivos planteados a continuación. Por último, facilitará y optimizará la comunicación interna de la empresa de cara a disponer de procesos de evaluación y control más eficientes responsabilizando al área de marketing de los resultados obtenidos.

Low Effort L-i Nuclear Fusion Plasma Control Using Model Predictive Control Laws

One of the main problems of fusion energy is to achieve longer pulse duration by avoiding the premature reaction decay due to plasma instabilities. The control of the plasma inductance arises as an essential tool for the successful operation of tokamak fusion reactors in order to overcome stability issues as well as the new challenges specific to advanced scenarios operation. In this sense, given that advanced tokamaks will suffer from limited power available from noninductive current drive actuators, the transformer primary coil could assist in reducing the power requirements of the noninductive current drive sources needed for current profile control. Therefore, tokamak operation may benefit from advanced control laws beyond the traditionally used PID schemes by reducing instabilities while guaranteeing the tokamak integrity. In this paper, a novel model predictive control (MPC) scheme has been developed and successfully employed to optimize both current and internal inductance of the plasma, which influences the L-H transition timing, the density peaking, and pedestal pressure. Results show that the internal inductance and current profiles can be adequately controlled while maintaining the minimal control action required in tokamak operation.
