The International System is a self-organized system and shows emergent behavior. During the timeframe (1495 - 1945), a finite-time singularity and four accompanying accelerating log-periodic cycles shaped the dynamics of the International System. The accelerated growth of the connectivity of the regulatory network of the International System, in combination with its anarchistic structure, produce and shape the war dynamics of the system. Accelerated growth of the connectivity of the International system is fed by population growth and the need for social systems to fulfill basic requirements. The finite-time singularity and accompanying log-periodic oscillations were instrumental in the periodic reorganization of the regulatory network of the International System, and contributed to a long-term process of social expansion and integration in Europa. The singularity dynamic produced a series of organizational innovations. At the critical time of the singularity (1939) the connectivity of the system reached a critical threshold, resulting in a critical transition. This critical transition caused a fundamental reorganization of the International System: Europe transformed from an anarchistic system to cooperative security community. This critical transition also marks the actual globalization of the International System. During the life span of cycles, the war dynamics show chaotic characteristics. Various early-warning signals can be identified, and can probably be used in the current International System. These findings have implications for the social sciences and historical research.
Sir Tim Berners-Lee invented the World Wide Web 25 years ago. So it’s worth a listen when he warns us: There’s a battle ahead. Eroding net neutrality, filter bubbles and centralizing corporate control all threaten the web’s wide-open spaces. It’s up to users to fight for the right to access and openness. The question is, What kind of Internet do we want?
“Vienna, 28 July 1914 — The Royal Serbian Government not having answered in a satisfactory manner the note of July 23, 1914, presented by the Austro-Hungarian Minister at Belgrade, the Imperial and Royal Government are themselves compelled to see to the safeguarding of their rights and interests, and, with this object, to have recourse to force of
The éToile Platform supports students aiming to participate in the ECCS14 - European Conference in Complex Systems, Lucca, Sept 22-26, 2014 ( http://eccs14.eu ). 10 registrations will be offered to students according to their contributions to the platform.
Master and PhD students, from any university, are invited to register in the platform and improve their reputation within the new éToile community.
Both ants and brains actually rely on two types of feedback, held in a delicate balance: negative (or inhibitory) feedback, and positive (or excitatory) feedback. “Negative feedback tends to cause stability. Positive feedback tends to cause runaway behavior,” said Tomer Czaczkes, an ant biologist at the University of Regensburg in Germany. “These two simple rules make something very powerful.”

There is mounting evidence that the heart is a system onto itself and that it is intimately intertwined with the nervous and endocrine system residing within its borders. The capacity of self-organized systems to adapt is embodied in the functional organization of the intrinsic control mechanisms. How these regulatory subsystems communicate and how uncoupling of the hierarchical organization results in loss of adaptive "fitness"remains a challenge in human biology. The principles by which "emergent properties" and functional order of a self-organizingsystem, such as the heart, achieve (homeo)dynamic stability provide a non-reductionist framework for understanding how biological system adapts to imposed internal and external stresses, e.g., ischemia, organ/tissue transplantation. In particular, the newly emergent dynamics of cardiac rhythm observed after the heart is transplanted may reflect a more stable,versatile and adaptive (as per "law of requisite variety") bipartite whole. The integrative action of the living organism can not be gotten from their concatenated fractions but is evolved "relationally", i.e., it emanates from emergent internal requirements of the constitutive parts.

Mathematical model shows how hundreds of starlings coordinate their movements in flight.
A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium.
Nella vetrificazione, il processo nel quale il vetro allo stato liquido, raffreddandosi, diventa solido, l'insieme delle configurazioni possibili per le molecole ha una struttura frattale. Lo ha dimostrato un nuovo studio di fisica matematica i cui risultati sono stati confermati da una simulazione numerica
Complexity Institute's insight:
"In termini matematici, un frattale è uno oggetto geometrico dotato di una invarianza di scala: in pratica, esso sembra avere la stessa struttura a qualunque scala dimensionale lo si consideri. Le strutture frattali si ritrovano spesso in natura, e accomunano oggetti incredibilmente diversi tra loro, quali possono essere per esempio un broccolo romanesco, un tratto di costa e il bordo di una foglia."
Qualsiasi sistema vivente o sociale, se isolato dall’ambiente esterno, degrada, si decompone e scompare: dalle teorie dei sistemi complessi adattativi emerge un’analisi scientifica allarmante della crisi economica attuale.
The best way to lose weight is to eat less and exercise more. But as a strategy to combat obesity at the population level, this common-sense prescription is proving ineffective over the long term. Tailored treatment programmes that factor in the stresses and temptations of the real world, using insights from behavioural research, are showing some success. Drugs may also form part of the solution. Or perhaps the pharmaceutical option should be a last resort, and society should instead use the power of government regulation to encourage healthier lifestyle options.

The Course Syllabi database contains a collection of annotated links to course syllabi related to complex systems. These syllabi can be searched according to class topics, institution, instructor, education level, and several other attributes. These syllabi will be useful for instructors developing their own courses on various topics, as well as serving as guides to people who want to learn on their own.

Conveying scientific content with accuracy and fluency takes practice and requires deep understanding of the concepts being conveyed. This depth of knowledge comes from internalizing information and constructing it into a form that is unique and coherent to the individual. Often in science classrooms there is little or no opportunity for students to practice this type of thinking, activities that we believe are fundamental to effective science communication. This article describes the use of haiku – a 17 syllable poem – as a means for students to convey neurobiological concepts in a succinct manner by forcing them to focus on the most salient features of the observed processes. In our assignments haiku writing was successfully paired with explanations of the students’ thought processes (Addiction course) or the scientific evidence to support claims (Neurodegenerative Disease course). We provide examples of student haiku and explanations as evidence of the power of this approach. The coupling of poetry and prose together create rich, accurate descriptions of scientific phenomena by encouraging higher-order thinking. Poetry writing can thus be used across the curriculum to forge comprehension of complex ideas in any discipline and to bridge the arts and the sciences.
