In- and Out-Groups

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

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,...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Stability of structures

Stability of structures

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Equity Theory

Equity Theory

Equity theory explains how our sense of fairness influences the dynamics of close relationships. Rooted in social psychology, the theory posits that individuals evaluate fairness by comparing the ratio of their contributions to the rewards they receive. Relationship satisfaction is highest when these ratios are perceived as balanced between partners, promoting mutual reciprocity and a sense of justice.Equity vs. Equality in RelationshipsEquity is distinct from equality. Fairness does not...

Background:

Community structure is a key network property in social and biological systems.
Modularity optimization is a popular community detection method.
Existing methods struggle with unbalanced community structures and the resolution limit problem.

Purpose of the Study:

To develop a novel metric for characterizing community structures, especially unbalanced ones.
To propose a method for inferring the number of communities, overcoming resolution limits.
To create an improved algorithm for community structure identification.

Main Methods:

Introduction of a new metric for community structure characterization.
Development of a method to infer the number of communities.
Algorithm design based on eigendecompositions for community identification.

Main Results:

The proposed metric offers better characterization of unbalanced community structures.
The new method effectively infers the number of communities, mitigating the resolution limit.
The eigendecomposition-based algorithm demonstrates superior performance on simulated and real data.

Conclusions:

The novel approach enhances community detection in networks with unbalanced structures.
The method provides a solution to the resolution limit problem in community detection.
The developed algorithm offers improved accuracy and performance for identifying network communities.
