Rivero Casas, Jesús2025-04-112025-04-112025-04-11http://hdl.handle.net/10393/50338https://doi.org/10.20381/ruor-31018This doctoral thesis presents a comprehensive analysis of the emergence of collective identities and social organization among youth for political participation, specifically focusing on Ateneo Nacional de la Juventud, an organization led by young Mexicans. The research sought to understand how collective identity emerged and impacted the members of this organization, employing the theoretical perspective of post-Marxism and the sociology of public action. The study delves into the articulatory practices carried out by Ateneistas to establish itself as a political subject participating in public action and explores the evolution of the Ateneista subjectivity. It also places a significant emphasis on the role of digital social networks in the organization's processes, reflecting the increasing influence of technology on social organizations. Theoretical and empirical literature reviews on youth and civil society organizations (CSOs) have been conducted to contextualize the study within the current socio-economic system of late capitalism. The need to redefine youth within the context of late capitalism is addressed, emphasizing the impact of globalization, job insecurity, and educational extension on the lives of young individuals. The study also underscores the active participation of young people in the social and political sphere to improve their living conditions, emphasizing the role of social organizations in generating critical awareness and providing a frame of reference for youth engagement. This thesis aims to contribute a nuanced understanding of youth participation in the social and political sphere, particularly through digital social networks, and its implications for social change in a moment where social movements have detached from the workers' movement. The findings will inform and stimulate theoretical debates on youth studies, post-Marxism and the sociology of public action. Additionally, it offers practical insights for youth organizations like Ateneo that seek to empower individuals to influence positive social transformations.enYouth studiesCollective identitiesPost-MarxismDigital social networksYouth political participationAteneo Nacional de la JuventudPolitical subjectsPolitical subjectivitiesBecoming a Public Action Subject: Articulatory Practices and Political Subjectivity in Mexico's Ateneo Nacional de la JuventudThesis
