Motivational Cycle01:20

Motivational Cycle

1.2K
The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

Structure of Self01:29

Structure of Self

864
Sigmund Freud's model of the human psyche is often illustrated using an iceberg analogy. The iceberg's visible tip represents the conscious mind, which includes thoughts and perceptions that individuals are immediately aware of. However, the larger, submerged portion of the iceberg represents the unconscious mind, a reservoir of repressed desires, instincts, and memories. According to Freud, human behavior is primarily shaped by this hidden realm.
Components of the Mind: Id, Ego, and...

Self-Regulation01:25

Self-Regulation

281
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

343
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Internal and External Forces01:12

Internal and External Forces

16.4K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

Steady Flow of a Fluid Stream01:27

Steady Flow of a Fluid Stream

786
Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

Area of Science:

  • Systems Dynamics
  • Operations Research
  • Management Science

Background:

  • Existing co-flow structures inadequately model internal, goal-directed attribute changes within material stocks.
  • Hines' co-flow structure uses information delay for external attribute changes, but not internal ones.

Purpose of the Study:

  • To develop a novel co-flow structure capable of modeling both internal and external attribute changes.
  • To provide an exact, dynamic solution for analyzing the equilibrium and non-equilibrium behavior of this new structure.

Main Methods:

  • Extension of the Hines co-flow structure by incorporating a first-order information delay.
  • The delay models both external attribute changes from the material stock and internal changes driven by goals.
  • Development of an exact, dynamic solution for the proposed co-flow model.

Main Results:

  • The new co-flow structure accurately models internal, goal-directed attribute modifications.
  • The dynamic solution allows for precise analysis of equilibrium and non-equilibrium states.
  • Demonstrated applicability through examples, including management programs to enhance employee loyalty.

Conclusions:

  • The proposed co-flow structure offers a more comprehensive approach to modeling dynamic systems with internal goals.
  • This model enhances the understanding and management of attribute changes in fundamental materials like employee bases.
  • Provides a foundation for designing effective management interventions targeting specific attribute improvements.
