The widespread deployment of wireless mobile communications enables an almost permanent usage of portable devices, which imposes high demands on the battery of these devices. Indeed, battery lifetime is becoming one the most critical factors on the end-users satisfaction when using wireless communications. In this work, the optimized power save algorithm for continuous media applications (OPAMA) is proposed, aiming at enhancing the energy efficiency on end-users devices. By combining the application specific requirements with data aggregation techniques, {OPAMA} improves the standard {IEEE} 802.11 legacy Power Save Mode (PSM) performance. The algorithm uses the feedback on the end-user expected quality to establish a proper tradeoff between energy consumption and application performance. {OPAMA} was assessed in the OMNeT++ simulator, using real traces of variable bitrate video streaming applications, and in a real testbed employing a novel methodology intended to perform an accurate evaluation concerning video Quality of Experience (QoE) perceived by the end-users. The results revealed the {OPAMA} capability to enhance energy efficiency without degrading the end-user observed QoE, achieving savings up to 44 when compared with the {IEEE} 802.11 legacy PSM.

En Procesos interculturales. Antropología política del pluralismo cultural en América Latina, Miguel Alberto Bartolomé retoma la discusión sobre el pluralismo cultural en América Latina y el multiculturalismo en países de inmigración multinacional, principalmente del ámbito anglosajón. Y la retoma para hacerla avanzar un paso hacia delante. La riqueza de esta obra no se puede sintetizar en esta breve reseña, por lo que aquí me referiré solamente a los conceptos que propone.
