Is Robert Merton's strain-theory reformulation of anomie a faithful development of Émile Durkheim's original concept, or a substantially different theory that merely borrows Durkheim's term?

Durkheim's anomie (1893, 1897) covers both acute, crisis-driven normlessness and a more chronic form of unregulated desire, while Merton's mid-20th-century strain theory narrows the concept to a structural mismatch between culturally prescribed success goals and the legitimate means to achieve them; scholars disagree on how much continuity actually exists between the two versions.
