Balance theory is useful in examining how celebrity endorsement affects consumers' attitudes toward products. [6] If a person likes a celebrity and perceives (due to the endorsement) that said celebrity likes a product, said person will tend to like the product more, in order to achieve psychological balance.
Structural balance theory posits that some types of triads are forbidden and others are permitted on the basis of four rules. [4]Using the term “friend” to designate a positive sentiment and the term “enemy” to designate a negative sentiment, the classic balance model defines a sentiment network as balanced if it contains no violations of four assumptions:
Balance Theory was first developed by Heider with Gestalt influences. [5] Gestalt psychology posits that there is a tendency towards perceptual simplicity, such as symmetry and continuation. Heider extends this principle to social relations, where there are balanced and imbalanced states. [ 6 ]
The balance of power theory is a core tenet of both classical and neorealist theory and seeks to explain alliance formation. Due to the neorealist idea of anarchism as a result of the international system, states must ensure their survival through maintaining or increasing their power in a self-help world.
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
The balance of threat theory modified realism (as well as the neorealism of Kenneth Waltz) by separating power from threat. In the balance of power theory, which had previously dominated realist analyses, states balance against others whose power (military capabilities) was rising. Greater power was assumed to reflect offensive intentions.
In the area of graph theory in mathematics, a signed graph is a graph in which each edge has a positive or negative sign. A signed graph is balanced if the product of edge signs around every cycle is positive. The name "signed graph" and the notion of balance appeared first in a mathematical paper of Frank Harary in 1953. [1]
Triadic closure is a concept in social network theory, first suggested by German sociologist Georg Simmel in his 1908 book Soziologie [Sociology: Investigations on the Forms of Sociation]. [1] Triadic closure is the property among three nodes A, B, and C (representing people, for instance), that if the connections A-B and A-C exist, there is a ...
