Love is All You Need: Clauset˙˙s fruitless search for scale-free networks

In the past weeks, I have received several requests to address the merits
of the Anna D. Broido and Aaron Clauset (BC) preprint [1] and their
fruitless search for scale-free networks in nature. The preprint˙˙s
central claim is deceptively simple: It starts from the textbook
definition of a scale-free network as a network with a power law in the
degree distribution [2]. It then proceeds to fit a power law to 927
networks, finding that only 4% are scale-free. The author's conclusion
that ˙˙scale-free networks are rare,˙˙ is turned into the title of the
preprint, helping it to get maximal attention. It worked˙˙Quanta magazine
accepted its conclusions without reservations. AfterThe Atlantic carried
the article, the un-refereed preprint received a degree of media exposure
that the original discovery of scale-free networks never enjoyed.
While I saw the conceptual problems with the manuscript, I was convinced
that the paper must be technically proficient. Yet, once I did dig into
it, it was a real ride. If you have the patience to get to the end of this
commentary, you will see where it fails at the conceptual level. But, we
will learn that it also fails, repeatedly, at the technical level.

Bots sustain and inflate striking opposition in online social systems
Societies are complex systems which tend to polarize into sub-groups of
individuals with dramatically opposite perspectives. This phenomenon is
reflected -- and often amplified -- in online social networks where,
however, humans are no more the only players, and co-exist alongside with
social bots, i.e. software-controlled accounts. Analyzing large-scale
social data collected during the Catalan referendum for independence on
October 1 2017, consisting of nearly 4 millions Twitter posts generated by
almost 1 million users, we identify the two polarized groups of
Independentists and Constitutionalists and quantify the structural and
emotional roles played by social bots. We show that bots act from
peripheral areas of the social system to target influential humans of both
groups, mostly bombarding Independentists with negative and violent
contents, sustaining and inflating instability in this online society.
These results quantify the potential dangerous influence of political bots
during voting processes.

The objective of the 10th congress of the European Union for Systemics (EUS) is to develop a systemic representation of the processes inherent to crises during interdisciplinary meetings, combined with a trans-disciplinary vision. This systemic representation will provide theoretic, methodological and practical tools applicable to specific cases of systems in crisis. All these resources will help the agent taking relevant actions for the benefit of a society willing to reach a high level of sustainability for future generations.

Conflict and Convention in Dynamic Networks

An important way to resolve games of conflict (snowdrift, hawk˙˙dove, chicken) involves adopting a convention: a correlated equilibrium that avoids any conflict between aggressive strategies. Dynamic networks allow individuals to resolve conflict via their network connections rather than changing their strategy. Exploring how behavioral strategies coevolve with social networks reveals new dynamics that can help explain the origins and robustness of conventions. Here, we model the emergence of conventions as correlated equilibria in dynamic networks. Our results show that networks have the tendency to break the symmetry between the two conventional solutions in a strongly biased way. Rather than the correlated equilibrium associated with ownership norms (play aggressive at home, not away), we usually see the opposite host˙˙guest norm (play aggressive away, not at home) evolve on dynamic networks, a phenomenon common to human interaction. We also show that learning to avoid
conflict can produce realistic network structures in a way different than preferential attachment models.
