In this issue of Última Década, contemporary youth expressions and discourses are explored, with a focus on the relationship between young people and the school environment in two contributions from Argentina and Chile. The volume begins with an article by MARIANA CHAVES titled "Unfit and negative youth: current discursive formations and representations among the contemporary Argentina" Chaves presents prevailing characterizations of Argentine youth and draws certain parallels with frequently used notions in the broader Latin American region. She interprets that dominant perspectives on Latin American youth align with legal and repressive models of power.EN ESTA ENTREGA DE Última Década se abordan algunas expresividades y discursos juveniles contemporáneos, con énfasis en la relaciónentre jóvenes y mundo escolar con dos contribuciones (argentina y chilena); la cultura hip-hop desde los jóvenes iquiqueños, y las representaciones y discursos sobre juventud desde la realidad argentina.
