Scientific mobility is a complex phenomenon that shaped and driven by the identity and objectives of the many various actors taking part in it. While trying to understand the underlying dynamics of scientific mobility, a greater emphasis on understanding the complexities of scientists" subjectivity is required. Scientists operate within a meritocratic process that draws on their talent and professional socialization experiences and rewards them for recognized scholarship. Therefore scientists ascribe greater value to certain institutions (e.g., universities) and rank them relative to others. Because such perceptions can have powerful consequences on the career paths of scientists who become affiliated with these institutions, mobility is an obvious tactic of professional socialization. Mobility becomes a means for enhancing a scientists" prestige and reputation. This book applies theories and notions from the sociology of science onto the practice of scientific migrationand mobility in order to explain the dynamics of human movements in science.
