  2. Social dynamics - Wikipedia

    en.wikipedia.org/wiki/Social_dynamics

    The field of social dynamics brings together ideas from economics, sociology, social psychology, and other disciplines, and is a sub-field of complex adaptive systems or complexity science. The fundamental assumption of the field is that individuals are influenced by one another's behavior.

  3. Root locus analysis - Wikipedia

    en.wikipedia.org/wiki/Root_locus_analysis

    This is a technique used as a stability criterion in the field of classical control theory developed by Walter R. Evans which can determine stability of the system. The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter (see pole–zero plot).

  4. Stability theory - Wikipedia

    en.wikipedia.org/wiki/Stability_theory

    In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation , for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature ...

  5. Personality change - Wikipedia

    en.wikipedia.org/wiki/Personality_change

    While still uncertain, research suggests that genetics play a role in the change and stability of certain traits in a personality. [7] They have also discovered that environmental sources affect personality too. [8] The debate over nature versus nurture have pervaded the field of psychology since its beginning.

  6. Hierarchical structure of the Big Five - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_structure_of...

    Through an exploratory analysis of the Big Five literature, John Digman came up with two superordinate factors on a higher level than the Big Five. He referred to these factors as "alpha" and "beta". Alpha refers to a combination of agreeableness, conscientiousness and emotional stability (the inverse of neuroticism).

  7. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    Analysis. Analysis of the robustness of a SISO (single input single output) control system can be performed in the frequency domain, considering the system's transfer function and using Nyquist and Bode diagrams. Topics include gain and phase margin and amplitude margin. For MIMO (multi-input multi output) and, in general, more complicated ...

  8. Behavioural change theories - Wikipedia

    en.wikipedia.org/wiki/Behavioural_change_theories

    Each behavioural change theory or model focuses on different factors in attempting to explain behaviour change. Of the many that exist, the most prevalent are learning theories, social cognitive theory, theories of reasoned action and planned behaviour, transtheoretical model of behavior change, the health action process approach, and the BJ Fogg model of behavior change.

  9. Person–situation debate - Wikipedia

    en.wikipedia.org/wiki/Person–situation_debate

    People change situations by how they act and what they do in these situations. [ 28 ] A commonly used example of person-situation interaction is the Stanford prison experiment , where college students participated in a study that simulated a prison setting with some students acting as guards and others as prisoners.
