The Supercore for Normal Form Games

We study the supercore of a system derived from a normal form game. For the case of a finite game with pure strategies, we define a sequence of games and show that the supercore of that system coincides with the set of Nash equilibrium strategy profiles of the last game in the sequence. This result is illustrated with the characterization of the supercore for the n-person prisoners’ dilemma. With regard to the mixed extension of a normal form game, we show that the set of Nash equilibrium profiles coincides with the supercore for games with a finite number of Nash equilibria. For games with an infinite number of Nash equilibria this need not be no longer the case. Yet, it is not difficult to find a binary relation which guarantees the coincidence of these two sets.

Una imagen vale más que mil palabras: efectos de las advertencias sanitarias visuales en el descenso del consumo de tabaco: un estudio desde la perspectiva del marketing social

[ES] El tabaco está reconocido hoy día como un factor de riesgo muy importante en multitud de enfermedades, representando un grave riesgo para la salud pública. Entre las medidas previstas por la Organización Mundial de la Salud y por la Comisión Europea está la utilización de advertencias sanitarias sobre los efectos del tabaco en las personas. En España actualmente esas advertencias contienen solo texto.

El VIH: el origen, la patología y el tratamiento

The HIV (Human Immunodeficiency Virus) is a very important disease in the world, with approximately 35 million people infected. In this study we have tried to expose the main characters of the virus, explaining the disease and the illness associated to the HIV. Besides, we have explained the antiretroviral treatments that are the most important weapon against the HIV. However, any of these treatments do not eliminate the HIV in the human body. For this reason, we have been looking for the new treatments and researches that have been development in the last years, including vaccines and genetic resistance. In addition, we have described the situation of the SIV (Simian Immunodeficiency Virus) in Africa, because it is the origin of the disease. The prevalence of the virus in primates population is something that have being studied for the last years, because it could be a new threat to the human population. Finally, we have proposed the researches lines that seems to be more effective and the ones that, in a future, could eliminate the virus in the human body.
