In the early seventies, Hill and Grunner reported that more than 100 theories of group development existed. [1] Since then, other theories have emerged as well as attempts at contrasting and synthesizing them. As a result, a number of typologies of group change theories have been proposed. A typology advanced by George Smith (2001) based on the ...
Group dynamics is a system of behaviors and psychological processes occurring within a social group (intragroup dynamics), or between social groups (intergroup dynamics). The study of group dynamics can be useful in understanding decision-making behaviour, tracking the spread of diseases in society, creating effective therapy techniques, and ...
Examples of the use of groups in physics include the Standard Model, gauge theory, the Lorentz group, and the Poincaré group. Group theory can be used to resolve the incompleteness of the statistical interpretations of mechanics developed by Willard Gibbs , relating to the summing of an infinite number of probabilities to yield a meaningful ...
In mathematics and abstract algebra, group theory studies the algebraic structures known as groups.The concept of a group is central to abstract algebra: other well-known algebraic structures, such as rings, fields, and vector spaces, can all be seen as groups endowed with additional operations and axioms.
The forming–storming–norming–performing model of group development was first proposed by Bruce Tuckman in 1965, [1] who said that these phases are all necessary and inevitable in order for a team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results. He suggested that these inevitable phases were ...
The equilibrium model of group development (equilibrium model) is a sociological theory on how people behave in groups. The model theorizes that group members will work to maintain a balance, or equilibrium, between task-oriented (instrumental) and socio-emotional (expressive) needs. [1] [2] A group can be successful if it maintains this ...
Earlier, Alfred Tarski proved elementary group theory undecidable. [31] The period of 1960-1980 was one of excitement in many areas of group theory. In finite groups, there were many independent milestones. One had the discovery of 22 new sporadic groups, and the completion of the first generation of the classification of finite simple groups.
The multiple sequence model defines different contingency variables such as group composition, task structure, and conflict management approaches, which all affect group decision-making. [3] This model consists of 36 clusters for coding group communication and four cluster-sets, such as proposal growth, conflict, socio-emotional interests, and ...
