Juli Cèsar, tirà i visionari? : l'esfondrament de la República romana

Aquest treball emmarca la vida de Juli Cèsar en el procés d'esfondrament de la República romana i la guerra civil. La seva vida n'és el fil conductor. També hi ha anàlisis descontextualitzades d'aquesta vida (la lluita entre optimates i populares, els mandats extraordinaris, la figura dels tribuns de la plebs i l'imperialisme romà), necessaris per a entendre aquest pas de República a Principat.

Social media and political change: The case of the 2011 revolutions in Tunisia and Egypt

Throughout the past decade, social media have come on the scene of various popular revolts. Their role as tools of information and coordination of social movements, from the Iranian Green Movement in 2009 to the Arab uprisings in 2011, has been widely debated. In most cases, online activism through blogs, Facebook, Twitter or other forms of social media has allowed citizens to be part of a social networking exercise and to engage in a public sphere that would have otherwise been unreachable to them due to severe repression. In Tunisia and Egypt, social media helped protests start and expand thanks to their ability to coordinate and disseminate information quickly. The new information and communication tools were an influential factor in accelerating the revolutionary processes across the Arab world, albeit they cannot be seen as neither the spur nor the drivers of any revolution.
