Actor-network theory, often abbreviated as ANT:

The Muscle Temple Actor-network theory means that it maps relations that are simultaneously material (between things) and “semiotic” (between concepts). It assumes that many relations are both material and “semiotic”. For example, the interactions in a bank involve both people, their ideas, and technologies. Together these form a single network.    

According to actor-network theory, such actor-networks are potentially transient, existing in a constant making and re-making [1]. This means that relations need to be repeatedly “performed” or the network will dissolve. (The actors need to come to work each day, and the computers /cameras need to keep on running.)
