Students’ movement and participation in Latin-American psychology: historical and future perspectives

The historiographical paper presented is about the students’ activism and participation in the Latin American psychology. This aims are: 1) to provide a brief historic overview of the Latin American psychology; 2) to review on the students’ participation in the Latin American psychology; 3) to raise students’ future perspectives for the Latin American psychology. It is recognized that there is an extensive past of Latin American psychology and an emerging historiographical work that re fl ects that past.However, there are several historiographical gaps not covered yet by the investigations in the region. In this context, this paper wants to contribute to the study of the students’ activism and participation in the Latin American psychology construction. The historical perspective is supported by the renewed historiographical conception called instant history” which focuses on ancient and recent history at the same time. Indirect sources were used: articles, monographs and compiled editions.

Combatant recruitment and the outcome of war

Why do some civil wars terminate soon, with victory of one party over the other? What determines if the winner is the incumbent or the rebel group? Why do other conáicts last longer? We propose a simple model in which the power of each armed group depends on the number of combatants it is able to recruit. This is in turn a function of the relative ëdistanceíbetween group leaderships and potential recruits. We emphasize the moral hazard problem of recruitment: Öghting is costly and risky so combatants have the incentive to defect from their task. They can also desert altogether and join the enemy. This incentive is stronger the farther away the Öghter is from the principal, since monitoring becomes increasingly costly. Bigger armies have more power but less monitoring capacity to prevent defection and desertion. This general framework allows a variety of interpretations of what type of proximity matters for building strong cohesive armies ranging from ethnic distance to geographic dispersion. Di§erent assumptions about the distribution of potential Öghters along the relevant dimension of conáict lead to di§erent equilibria. We characterize these, discuss the implied outcome in terms of who wins the war, and illustrate with historical and contemporaneous case studies.
