Dear Reader, it is a pleasure to release the second issue of volume 4 of Encuentro Latinoamericano: Journal of Political Science and International Relations. This journal publishes in-depth studies on Latin American politics, bringing together students and academics from all over the continent and the world. As with every issue, we kindly thank all the external reviewers, based on various places in the world, who voluntary contributed to a rigorous review process that is reflected in the academic fundaments of the following articles. We are also thankful for the large response to our 'calling for papers', from students all around the world. Particularly, thanks to the authors that presented a diverse, original and interesting contribution to the understanding of Latin American politics. Vol. 4 No. 2 contains the following papers: "Brazilian institutional changes 1891-1967" by Larissa Rodrigues de Arruda (Brazil) addresses the institutional changes that occurred within the Brazilian regimes between 1891 and 1967. "Dilma Rousseff na Assembleia Geral das Nações Unidas: Os Discursos de 2011 e 2015" by Pedro Chapaval Pimentel and Luciana Panke (Brazil) analyses the first and last speeches delivered by President Dilma Rousseff in 2011 and 2015 at the United Nations General Assembly. "Democratic development and corruption perception in Latin America during 2002-2014: a widespread setback" by Alberto Vélez Valdés (Mexico) explores the democratic development in Latin American states during the period of 2002-2014, in a context of corruption perception and conventions against corruption. "Authoritarian Legacies in Guatemala's Democracy: Environmental rights defenders: the new threat to national security?" by Stéphanie Bacher (Canada) investigates the nature of the obstacles hindering environmental rights defenders' political participation against mining companies in Guatemala. Finally, Tiago Vales and Joe Sater (Brazil and Lebanon) argue that cyberspace and information technologies have become essential to many of the activities of contemporary society. The authors use the conceptual lenses of the Copenhagen School to investigate how Brazil securitises the use of cyberspace. We hope that you find these articles attractive, and look forward to your comments as well as submissions for our 2018 volume.
