Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Infection

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Intracellular Signaling Affects Focal Adhesions

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
Some...

Nonconscious Mimicry

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Cause and Effect

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Summary

This summary is machine-generated.

Random network rewiring accelerates contagion spread in noisy threshold models, contrary to previous findings. This discovery harmonizes network structure effects on contagion dynamics.

Area of Science:

Network Science
Epidemiology
Sociology

Background:

Biological contagion models often show random rewiring accelerates spread.
Threshold-based contagions were previously thought to spread faster on clustered networks.

Purpose of the Study:

To investigate how network structure influences the spread of threshold-based contagions.
To reconcile conflicting findings on network rewiring and contagion dynamics.

Main Methods:

Analysis of spread rate on circular lattices with rewired edges.
Simulations on empirical networks with varying rewiring probabilities and adoption reversibility.

Main Results:

Minor modifications to threshold models reverse previous findings.
Random rewiring accelerates spread in noisy threshold contagions with low adoption probability.
Results hold for partial rewiring, reversible decisions, and high-dimensional lattices.

Conclusions:

Network structure's impact on contagion is model-dependent.
Noisy threshold models exhibit accelerated spread with random rewiring.
Findings harmonize understanding of network topology and contagion dynamics.
