Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...
This theory was developed simultaneously in 1935 by Henry Eyring, then at Princeton University, and by Meredith Gwynne Evans and Michael Polanyi of the University of Manchester. [3] [4] [5] TST is also referred to as "activated-complex theory", "absolute-rate theory", and "theory of absolute reaction rates". [6]
In chemical kinetics, the entropy of activation of a reaction is one of the two parameters (along with the enthalpy of activation) that are typically obtained from the temperature dependence of a reaction rate constant, when these data are analyzed using the Eyring equation of the transition state theory.
The Change Management Foundation is shaped like a pyramid with project management managing technical aspects and people implementing change at the base and leadership setting the direction at the top. The Change Management Model consists of four stages: Determine Need for Change; Prepare & Plan for Change; Implement the Change; Sustain the Change
Complexity theory emphasizes interactions and the accompanying feedback loops that constantly change systems. While it proposes that systems are unpredictable, they are also constrained by order-generating rules. [6]: 74 Complexity theory has been used in the fields of strategic management and organizational studies.
Ralph Douglas Stacey (October 1948 – September 4 2021) was a British organizational theorist and Professor of Management at Hertfordshire Business School, University of Hertfordshire, in the UK and one of the pioneers of enquiring into the implications of the natural sciences of complexity for understanding human organisations and their management.
Complexity science is not a single theory—it encompasses more than one theoretical framework and is interdisciplinary, seeking the answers to some fundamental questions about living, adaptable, changeable systems. Complex adaptive systems may adopt hard or softer approaches. [8]
The U Process of Co-sensing and Co-creating — Presencing. Theory U is a change management method and the title of a book by Otto Scharmer. [1] Scharmer with colleagues at MIT conducted 150 interviews with entrepreneurs and innovators in science, business, and society and then extended the basic principles into a theory of learning and management, which he calls Theory U. [1] The principles ...
