Reflexive relation. In mathematics, a binary relation on a set is reflexive if it relates every element of to itself. [1][2] An example of a reflexive relation is the relation "is equal to" on the set of real numbers, since every real number is equal to itself. A reflexive relation is said to have the reflexive property or is said to possess ...
In epistemology, and more specifically, the sociology of knowledge, reflexivity refers to circular relationships between cause and effect, especially as embedded in human belief structures. A reflexive relationship is multi-directional when the causes and the effects affect the reflexive agent in a layered or complex sociological relationship.
A reflexive and symmetric relation is a dependency relation (if finite), and a tolerance relation if infinite. A preorder is reflexive and transitive. A congruence relation is an equivalence relation whose domain X {\displaystyle X} is also the underlying set for an algebraic structure , and which respects the additional structure.
Partial orders. A reflexive, weak, [1] or non-strict partial order, [2] commonly referred to simply as a partial order, is a homogeneous relation ≤ on a set that is reflexive, antisymmetric, and transitive. That is, for all it must satisfy: Reflexivity: , i.e. every element is related to itself.
An example is the relation being a parent: if Tess is a parent of Bob and Bob is a parent of Carol, then it is not automatically the case that Tess is a parent of Carol. [72] Another distinction is between reflexive and irreflexive relations. Reflexive relations are those in which each entity is related to itself.
For example, ≥ is a reflexive relation but > is not. Irreflexive (or strict) for all x ∈ X, not xRx. For example, > is an irreflexive relation, but ≥ is not. Coreflexive for all x, y ∈ X, if xRy then x = y. [7] For example, the relation over the integers in which each odd number is related to itself is a coreflexive relation.
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.
The reflexive stage is the first stage of social rejection and refers to the period immediately after social exclusion has occurred. During this stage, Williams proposed that ostracism uniquely poses a threat to four fundamental human needs ; [ 41 ] the need to belong, the need for control in social situations, the need to maintain high levels ...
