In the ashes of political and socio-economic collapse, social movements sometimes rise like a phoenix. Little more than a year has passed since the Tunisian uprisings, the spark that ignited a series of “mobilizations of the indignant” that spread like wildfire around the world. Many observers have reported on these unprecedented global protests. They have portrayed citizens who declare feeling marginalized if not scapegoated, and who reject the increasing inequalities between rich and poor, the declining mobility of most, and the “disclassment” of many. They have shown, as well, massive protests against governments and politicians that are perceived as indifferent at best, duplicitous at worst, and in any event as blatantly closed to popular concerns. Many journalists have indeed asked what took so long for people to protest given this fatal combination. For the social scientist, however, the questions of who, why and how mobilizes are not so simple. There are specific problematics of mediation between structure, culture and individual or collective agency that need to be addressed.

Effects of context on the perception of, and incidental memory for, real-world objects have predominantly been investigated in younger individuals, under conditions involving a single static viewpoint. We examined the effects of prior object context and object familiarity on both older and younger adults' incidental memory for real objects encountered while they traversed a conference room. Recognition memory for context-typical and context-atypical objects was compared with a third group of unfamiliar objects that were not readily named and that had no strongly associated context. Both older and younger adults demonstrated a typicality effect, showing significantly lower 2-alternative-forced-choice recognition of context-typical than context-atypical objects; for these objects, the recognition of older adults either significantly exceeded, or numerically surpassed, that of younger adults. Testing-awareness elevated recognition but did not interact with age or with object type. Older adults showed significantly higher recognition for context-atypical objects than for unfamiliar objects that had no prior strongly associated context. The observation of a typicality effect in both age groups is consistent with preserved semantic schemata processing in aging. The incidental recognition advantage of older over younger adults for the context-typical and context-atypical objects may reflect aging-related differences in goal-related processing, with older adults under comparatively more novel circumstances being more likely to direct their attention to the external environment, or age-related differences in top-down effortful distraction regulation, with older individuals' attention more readily captured by salient objects in the environment. Older adults' reduced recognition of unfamiliar objects compared to context-atypical objects may reflect possible age differences in contextually driven expectancy violations. The latter finding underscores the theoretical and methodological value of including a third type of objects-that are comparatively neutral with respect to their contextual associations-to help differentiate between contextual integration effects (for schema-consistent objects) and expectancy violations (for schema-inconsistent objects).

[ES]El objetivo de este proyecto es programar el control numérico para la mecanización del escudo del Real Madrid. Para conseguir esto, primero es necesario aprender cómo funcionan los programas que se van a usar. Después de esto se va a crear el archivo CAD, usando el programa Solid Edge. Luego, usando el programa SurfCam Velocity 4.0 se programará el control numérico necesario para la fabricación del escudo.

[EU]Gaur egun, Europa mailan European Rail Traffic Management System (ERTMS) seinaleztapen-sistema bateratua hedatzen ari dira trenbide sare desberdinen arteko elkar eragintasuna bultzatzeko. Proiektu honen helburua da ERTMS sistemaren barneko ETCS protokoloa hedatzea simulazio hibridodun ingurune batean, ERTMS sistemaren hedatzea azkartuko duten erakusleak sortuz. Horretarako, OPNET simulagailuaren System-in-the-loop erreminta erabili da. Erreminta hau baliatuz ETCS protokoloaren pakete errealak ingurune simulatuan integratzeko funtzioen liburutegi bat idatzi da. Amaitzeko, liburutegi hori baliatuz ETCS protokoloak sareko arazoen aurrean duen errendimenduaren analisi bat burutu da eta liburutegi berri horrek pakete errealak simulatuetara itzultzean (eta kontrakoa) duen errendimendua zein den aztertu da.

[ES] El objetivo del presente trabajo de investigación es la elaboración de un programa de intervención de actividades acuáticas dirigido a personas con parálisis cerebral en ASPACE de Vitoria-Gasteiz (Álava). Se han diseñado, aplicado y evaluado las actividades en función de los objetivos pretendidos en el programa. Consideramos que su puesta en práctica servirá para favorecer la convivencia entre nuestros participantes del programa. Este programa pretende ser un modelo de acción que puede ser aplicado tanto en el ámbito del ocio y del tiempo libre como en el ámbito educativo, considerados estos estos como elementos favorecedores de su desarrollo

[ES] El artículo trata el tema de las estructuras tumulares, su variabilidad formal y funcional (funeraria, lugar de habitación, etc.), así como su distinta cronología. Se describe los casos concretos de Txoritegi (Zerain —Gipuzkoa—) y Galardi (Txoritegi —Gipuzkoa—), unas estructuras tumulares tipo mota utilizadas, posiblemente, a modo de atalaya de vigía en el contexto del período de conflictividad bajomedieval. Es un elemento novedoso en el territorio para cuya interpretación se ha efectuado un análisis de las cuencas visuales mediante SIG.
