This issue 41 of Revista Última Década marks the beginning of the fruitful collaboration both nationally and internationally that has been cultivated. Not only have we expanded the Editorial Committee, but we have also taken a new step by committing to joint action with periodic publications on childhood and youth, as adopted in Manizales, Colombia, within the framework of the I Latin American Biennial of Childhood and Youth. These innovations will be communicated soon through our website and email to our subscribers.
