Structure and dynamics is the name of a subfield in the social sciences, used particularly in social anthropology and sociology, which connotes that while structure is an important concept in social theory, contemporary social theory has long since moved beyond structural functionalism, which was identified with Radcliffe-Brown and Talcott Parsons. It is also an important subfield in the complexity sciences.
