Circular cumulative causation. Circular cumulative causation is a theory developed by Swedish economist Gunnar Myrdal who applied it systematically for the first time in 1944 (Myrdal, G. (1944), An American Dilemma: The Negro Problem and Modern Democracy, New York: Harper). It is a multi-causal approach where the core variables and their ...
Directed acyclic graph. In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called arcs), with each edge directed from one vertex to another, such that following those directions will never form a closed loop ...
A system archetype is a pattern of behavior of a system. Systems expressed by circles of causality have therefore similar structure. Identifying a system archetype and finding the leverage enables efficient changes in a system. The basic system archetypes and possible solutions of the problems are mentioned in the section Examples of system ...
A causal loop diagram (CLD) is a causal diagram that aids in visualizing how different variables in a system are causally interrelated. The diagram consists of a set of words and arrows. Causal loop diagrams are accompanied by a narrative which describes the causally closed situation the CLD describes. Closed loops, or causal feedback loops, in ...
Cybernetics is the transdisciplinary study of circular processes such as feedback systems where outputs are also inputs. It is concerned with general principles that are relevant across multiple contexts, [1] including in ecological, technological, biological, cognitive and social systems and also in practical activities such as designing, [2] learning, and managing.
Systems theory is the transdisciplinary [1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.
Judea Pearl defines a causal model as an ordered triple ,, , where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U ...
circular causal loops rather than linear causality, self-organization, observation as part of or directly related to systems, and; reflexivity or interaction between a system and what is known about it. Holistic Symmetry in Modern Science, webtext by Gary Witherspoon, 3 April 2007.
