Interpretive Paradigm (subjective-regulation)
This paradigm "seeks to explain the stability of behavior from the individual's viewpoint". Researchers in this paradigm try to observe "on-going processes" to better understand individual behavior and the "spiritual nature of the world".
Radical Humanist Paradigm (subjective-radical change)
Theorists in this paradigm are mainly concerned with releasing social constraints that limit human potential. They see the current dominant ideologies as separating people from their "true selves". They use this paradigm to justify desire for revolutionary change. It's largely anti-organization in scope.
Radical Structuralist Paradigm (objective-radical change)
Based on this paradigm, theorists see inherent structural conflicts within society that generate constant change through political and economic crises. This has been the fundamental paradigm of Marx, Engles, and Lenin.
