Actor–network theory ( ANT) is a theoretical and methodological approach to social theory where everything in the social and natural worlds exists in constantly shifting networks of relationships. It posits that nothing exists outside those relationships. All the factors involved in a social situation are on the same level, and thus there are ...
Network science. A social network diagram displaying friendship ties among a set of Facebook users. Social network analysis ( SNA) is the process of investigating social structures through the use of networks and graph theory. [1] It characterizes networked structures in terms of nodes (individual actors, people, or things within the network ...
The actor model adopts the philosophy that everything is an actor. This is similar to the everything is an object philosophy used by some object-oriented programming languages. An actor is a computational entity that, in response to a message it receives, can concurrently: send a finite number of messages to other actors;
Network science. A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories ...
Structuration theory. The theory of structuration is a social theory of the creation and reproduction of social systems that is based on the analysis of both structure and agents (see structure and agency ), without giving primacy to either. Furthermore, in structuration theory, neither micro - nor macro-focused analysis alone is sufficient.
System context diagram. Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram .
Structure and agency. In the social sciences there is a standing debate over the primacy of structure or agency in shaping human behaviour. Structure is the recurrent patterned arrangements which influence or limit the choices and opportunities available. [1] Agency is the capacity of individuals to act independently and to make their own free ...
Actors are the primitives that form the basis of the Actor model of concurrent digital computation. In response to a message that it receives, an Actor can make local decisions, create more Actors, send more messages, and designate how to respond to the next message received. Actor model theory incorporates theories of the events and structures ...
