Editorial
Abstract
Interest in the processes of mobility and international migration of skilled personnel, as well as concern about their dynamics and their impacts on national science, technology, and innovation systems, are recurring themes in the reflection and design of public policies in many countries, including those in Latin America. The first intellectual approaches to the issue of brain drain date back to the early 1960s, when the effects of the pull exerted by the United States' scientific and technological system on professionals from Europe and some less developed countries had already become visible. Since then, the topic has experienced ups and downs in attention, depending on its public visibility at specific moments.
