TLDR
It is discovered that complex contagions require a critical mass of infected nodes that corresponds to a phase transition in the ability of the contagion to take advantage of the “shortcuts” created by long-range ties.About:

Complex Contagions: A Decade in Review
TL;DR: Recent advancements in applied studies of complex contagions, particularly in the domains of health, innovation diffusion, social media, and politics are discussed, including both diversity of demographic profiles among local peers and the broader notion of structural diversity within a network.
Journal ArticleDOI
The weakness of tie strength
TL;DR: Empirical analyses and simulation models reveal new types of ties, as well as the conventional variety, that open promising research avenues.

Complex social contagion makes networks more vulnerable to disease outbreaks
TL;DR: In this paper, the authors build on mounting evidence that health behaviors -such as vaccination, and refusal thereof - can spread across social networks through a process of complex contagion that requires social reinforcement.
Complex social contagion makes networks more vulnerable to disease
TL;DR: In this article, the authors build on mounting evidence that health behaviors -such as vaccination, and refusal thereof - can spread across social networks through a process of complex contagion that requires social reinforcement, and they find that the process by which the health behavior spreads has a very strong effect on disease outbreak dynamics.

Complex contagions and the diffusion of popular Twitter hashtags in Nigeria
TL;DR: It is found that hashtags related to Nigerian sociopolitical issues, including the #bringbackourgirls hashtag, are more likely to be adopted among densely connected users with multiple network neighbors who have also adopted the hashtag, compared to mainstream news hashtags.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Diffusion of Innovations
TL;DR: A history of diffusion research can be found in this paper, where the authors present a glossary of developments in the field of Diffusion research and discuss the consequences of these developments.

Statistical mechanics of complex networks
TL;DR: In this paper, a simple model based on the power-law degree distribution of real networks was proposed, which was able to reproduce the power law degree distribution in real networks and to capture the evolution of networks, not just their static topology.

Threshold models of collective behavior.
TL;DR: This article developed models of collective behavior for situations where actors have two alternatives and the costs and/or benefits of each depend on how many other actors choose which alternative, and the key...
