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,...

Impact of Groups on Groups

Impact of Groups on Groups

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Assembly of Signaling Complexes

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Deindividuation

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Understanding Deception

Understanding Deception

Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

Summary

This summary is machine-generated.

We introduce Surprise (S), a new global parameter for analyzing complex networks. Maximizing S efficiently characterizes community structure, outperforming existing methods like modularity (Q) on synthetic and real-world networks.

Area of Science:

Complex network analysis
Network science
Data mining

Background:

Characterizing community structure is a fundamental challenge in network analysis across various scientific disciplines.
Existing methods, such as Newman and Girvan's modularity (Q), have limitations in accurately defining network communities.

Purpose of the Study:

To introduce and evaluate a novel global parameter, Surprise (S), for efficient and accurate community structure characterization in complex networks.
To compare the performance of Surprise (S) against established methods like modularity (Q).

Main Methods:

Development and application of the Surprise (S) parameter.
Utilizing standard and novel benchmarks for synthetic network analysis.
Testing S maximization on real-world network datasets.

Main Results:

Surprise (S) maximization provides a highly efficient method for characterizing community structure in complex synthetic networks.
S qualitatively outperforms modularity (Q) in community detection.
Application to real networks yields natural partitions and reveals limitations in current understanding.

Conclusions:

Surprise (S) offers an effective global criterion for defining community structure in complex networks.
This approach opens new avenues for understanding the intricate organization of complex systems.
The method highlights areas where existing knowledge of network structures may be incomplete.
