Distribution Reliability and Automation01:25

Distribution Reliability and Automation

422
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

153
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Non-equilibrium in the Cell

5.2K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Autocrine Signaling01:01

Autocrine Signaling

51.2K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

Under normal physiological conditions, autocrine signaling is essential for maintaining homeostasis. This process is well characterized in...

Robbers Cave

14.6K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Social Loafing01:37

Social Loafing

38.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Area of Science:

  • Behavioral Economics
  • Computational Social Science
  • Network Science

Background:

  • Cooperation in human groups is inherently unstable and tends to decay over time.
  • Mechanisms to sustain cooperation are crucial but often insufficient.
  • Understanding factors that promote group cooperation is a key challenge.

Purpose of the Study:

  • To investigate whether autonomous agents (bots) can stabilize and promote cooperation in human groups.
  • To test the efficacy of network-intervention strategies using bots in a public-goods game.
  • To compare bot-driven network interventions with other strategies like tit-for-tat.

Main Methods:

  • Conducted theoretically informed experiments with 1,024 human subjects across 64 networks playing a public-goods game.
  • Introduced autonomous agents (bots) programmed with local knowledge to intervene in human partner selections.
  • Implemented network-intervention strategies and compared outcomes with baseline and tit-for-tat bot strategies.

Main Results:

  • Cooperation rates in human groups increased from 60.4% at baseline to 79.4% with bot intervention.
  • The network-intervention strategy using bots significantly outperformed other strategies, including tit-for-tat bots.
  • Even a single bot employing a mixed strategy could foster cooperative clusters and increase group cooperation.

Conclusions:

  • Simple artificial intelligence can effectively stabilize and enhance cooperation in human groups.
  • Bot-driven network interventions represent a powerful strategy for managing social dilemmas.
  • The findings highlight the potential of AI to positively influence human social dynamics and cooperation.
