A new appraisal of the relationship between the Presidency and Congress in Argentina over the first two decades of its democratic regime. Mariana Llanos uses the processes of privatization and state reform in Argentina to reassess the performance, functions, and stature of these institutions as the country embarked on a program of change. This is a valuable contribution to the debate on the development of political institutions in Latin America.

This volume is the first comprehensive analysis of a new type of executive instability without regime instability in Latin America referred to as "presidential breakdown." It includes a theoretical introduction framing the debate within the institutional literature on democracy and democratization, and the implications of this new type of executive instability for presidential democracies. Two comparative chapters analyze the causes, procedures, and outcomes of presidential breakdowns in a regional perspective, and country studies provide in-depth analyses of all countries in Latin America that have experienced one or several presidential breakdowns: Argentina, Bolivia, Brazil, Dominican Republic, Ecuador, Guatemala, Paraguay, Peru, and Venezuela. The book also includes an epilogue on the 2009 presidential crisis in Honduras.

Proceedings of the Sixteenth International Workshop held in San Juan, Puerto Rico in June 1992. Papers are divided into a broad range of topics: solid state physics, superconductivity, quantum fluids, nuclear physics, atoms and molecules, classical fluids, polymers, plasmas, lattice theories, phase transitions, cellular automata, and fundamental quantum mechanics. Participants discussed density function theory, dynamics of metal films, coulomb coupling, nucleonic superfluids, time-dependent n-level systems, fluids of hard convex molecules, and line tension at wetting and pre-wetting transitions.
