The Web of Human Sexual Contacts
TLDR
In this article, the authors analyze data on the sexual behavior of a random sample of individuals, and find that the cumulative distributions of the number of sexual partners during the twelve months prior to the survey decays as a power law with similar exponents for females and males.Abstract:
Many ``real-world'' networks are clearly defined while most ``social'' networks are to some extent subjective. Indeed, the accuracy of empirically-determined social networks is a question of some concern because individuals may have distinct perceptions of what constitutes a social link. One unambiguous type of connection is sexual contact. Here we analyze data on the sexual behavior of a random sample of individuals, and find that the cumulative distributions of the number of sexual partners during the twelve months prior to the survey decays as a power law with similar exponents $\alpha \approx 2.4$ for females and males. The scale-free nature of the web of human sexual contacts suggests that strategic interventions aimed at preventing the spread of sexually-transmitted diseases may be the most efficient approach.read more

The impact of awareness on epidemic spreading in networks
TL;DR: It is shown that the global awareness cannot decrease the likelihood of an epidemic outbreak while both the local awareness and the contact awareness can, and the influence degree of the localawareness on disease dynamics is closely related with the contactawareness.

Individualization as driving force of clustering phenomena in humans.
TL;DR: A new model can explain cultural clustering in human societies by combining the integrative tendencies of social influence with the disintegrative effects of individualization, and is robust to “noise”—randomness is actually the central mechanism that sustains pluralism and clustering.

TL;DR: The extent of international linkage revealed by this comprehensive approach demonstrates the need to consider the global diversity of HIV, even when describing local epidemics, and the speed of this method allows for near-real-time surveillance of the pandemic's progression.
