Social Traps01:41

Social Traps

27.0K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Social Proof

32.5K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Reason and Intuition

7.6K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Design Example: Forces in Sluice Gate

3.4K
In hydraulic engineering, sluice gates are essential for managing water flow through channels, reservoirs, and irrigation systems. Sluice gates, acting as vertical barriers, regulate water by adjusting the gate's opening height, which changes the velocity and pressure of water flowing beneath the gate. Understanding the forces involved is crucial to designing sluice gates that can withstand dynamic pressure differences, especially when the gate is closed or partially open.

One-Compartment Open Model for Extravascular Administration: First-Order Absorption Model

648
The first-order absorption model for extravascular administration describes the rate at which a drug is absorbed and eliminated, following the principles of first-order kinetics. This model is vital as it provides a mathematical representation of drug behavior within the body. It also allows for the prediction and interpretation of drug absorption and elimination based on the rate of change in drug concentration over time. This model can be visualized as a plasma concentration-time profile...

Modeling with Differential Equations01:25

Modeling with Differential Equations

137
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...

  • Computational Social Science
  • Human Behavior Modeling

Background:

  • Pedestrian modeling and simulation are crucial for facility design and safety.

  • Collected data on pedestrian perception, distance to exits, and local density levels.
  • Analyzed pedestrian behavior using statistical methods and simulation.

Main Results:

  • Pedestrians utilize time-dependent information to make optimal exit choices.
  • Congested conditions lead to load balancing across available exits.
  • A minimal linear model based on exit distance and density accurately predicts egress behavior.

Conclusions:

  • Pedestrian exit choice is a dynamic process influenced by environmental cues.
  • A simplified linear model offers an efficient alternative to complex optimization methods for simulating load balancing.
  • The findings are particularly relevant for non-symmetrical facility designs and emergency egress scenarios.
