Social norms as solutions

    Climate change, biodiversity loss, antibiotic resistance, and other
global challenges pose major collective action problems: A group benefits
from a certain action, but no individual has sufficient incentive to act
alone. Formal institutions, e.g., laws and treaties, have helped address
issues like ozone depletion, lead pollution, and acid rain. However,
formal institutions are not always able to enforce collectively desirable
outcomes. In such cases, informal institutions, such as social norms, can
be important. If conditions are right, policy can support social norm
changes, helping address even global problems. To judge when this is
realistic, and what role policy can play, we discuss three crucial
questions: Is a tipping point likely to exist, such that vicious cycles of
socially damaging behavior can potentially be turned into virtuous ones?
Can policy create tipping points where none exist? Can policy push the
system past the tipping point?

Sensitivity of Complex Networks

    The sensitivity (i.e. dynamic response) of complex networked systems
has not been well understood, making difficult to predict whether new
macroscopic dynamic behavior will emerge even if we know exactly how
individual nodes behave and how they are coupled. Here we build a
framework to quantify the sensitivity of complex networked system of
coupled dynamic units. We characterize necessary and sufficient conditions
for the emergence of new macroscopic dynamic behavior in the thermodynamic
limit. We prove that these conditions are satisfied only for architectures
with power-law degree distributions. Surprisingly, we find that highly
connected nodes (i.e. hubs) only dominate the sensitivity of the network
up to certain critical frequency.

How complexity originates: Examples from history reveal additional roots to complexity

    Most scientists will characterize complexity as the result of one or
more factors out of three: (i) high dimensionality, (ii) interaction
networks, and (iii) nonlinearity. High dimensionality alone need not give
rise to complexity. The best known cases come from linear algebra: To
determine the eigenvalues and eigenvectors of a large quadratic matrix,
for example, is complicated but not complex. Every mathematician,
physicist or economist, and most scholars from other disciplines can write
down an algorithm that would work provided infinite resources in computer
time and storage space are given. (...)

Why I know but don˙˙t believe

    Despite extensive efforts at public science education, polling over the
past 30 years has consistently shown that about 40 to 45% of Americans
believe that humans were supernaturally created in the past 10,000 years
(1). A natural interpretation of this finding is that U.S. science
education is failing to reach nearly half of the population, and that
widespread belief in recent human origins reflects basic scientific
illiteracy. However, the reality is more complex (2): Many of those who
reject evolutionary theory are aware of the scientific consensus on the
subject, and such rejection is not always associated with low scientific
literacy. Similar results have been found for beliefs regarding
anthropogenic climate change (3). On page 321 of this issue, Friedkin et
al. (4) provide a key step toward understanding this phenomenon by
introducing a simple family of models for social influence among
individuals with multiple, interdependent beliefs.

Conference on Complex Systems 2017: Cancun, Mexico

The scientific study of complex systems offers a method for understanding how elements interact to give rise to global properties, while at the same time these properties constrain elements. Bringing together scholars and students from all fields, the Conference on Complex Systems will convene in September 17-22, 2017 in Latin America for the first time.

International Conference on Computational Social Science

    The 3rd Annual International Conference on Computational Social Science (IC2S2 2017) is an interdisciplinary event designed to engage a broad community of researchers ˙˙ academics, industry experts, open data activists, government agency workers, and think tank analysts ˙˙ dedicated to advancing social science knowledge through computational methods. IC2S2 2017 affords the opportunity to meet and discuss works in which social systems and dynamics are investigated in a quantitative way through large datasets that are either mined from various sources (e.g. social media, communication systems), or created via controlled experiments or computational modeling.
After successful events in Helsinki 2015 and Evanston, IL 2016, the 3rd IC2S2 will take place in Cologne, Germany on July 10-13.

Evidence of Shared Aspects of Complexity Science and Quantum Phenomena

    Complexity science concepts of emergence, self-organization, and
feedback suggest that descriptions of systems and events are subjective,
incomplete, and impermanent-similar to what we observe in quantum
phenomena. Complexity science evinces an increasingly compelling
alternative to reductionism for describing physical phenomena, now that
shared aspects of complexity science and quantum phenomena are being
scientifically substantiated. Establishment of a clear connection between
chaotic complexity and quantum entanglement in small quantum systems
indicates the presence of common processes involved in thermalization in
large and small-scale systems. Recent findings in the fields of quantum
physics, quantum biology, and quantum cognition demonstrate evidence of
the complexity science characteristics of sensitivity to initial
conditions and emergence of self-organizing systems. Efficiencies in
quantum superposition suggest a new paradigm in which our very notion of
complexity depends on which information theory we choose to employ.

* A 3-day Conference (June 21-23) featuring research in a wide range of topics and in different formats, including keynote and invited talks, oral presentations, posters, and lightning talks.

Abstracts for oral presentations, lightning talks, and posters are due January 15, 2017. Please read more details in the call. The Easy Chair submission portal will open by November 1 for submissions and will be located on this page (http://unam.us4.list-manage1.com/track/click?u=0eb0ac9b4e8565f2967a8304b&id=ae9d0edb88&e=55e25a0e3e) .


Proposals to run a full- or half-day satellite session before the main conference are due December 15, 2016 (http://unam.us4.list-manage1.com/track/click?u=0eb0ac9b4e8565f2967a8304b&id=504f3120d5&e=55e25a0e3e) .
