A framework towards understanding mesoscopic phenomena: Emergent unpredictability, symmetry breaking and dynamics across scales

Hong Qian, Ping Ao, Yuhai Tu, Jin Wang
2016 Chemical Physics Letters  
With these limits, symmetry breaking and cusp catastrophe are two perspectives of the same mesoscopic system on different time scales.  ...  The existence of these discrete states and the Markov transitions among them are both emergent phenomena.  ...  Robustness of a cellular state and punctuated equilibrium in state transitions are necessary consequences of this dynamics description.  ...

2006 Mathematical Modelling of Natural Phenomena  
We review the basic pathology of cyclical neutropenia in both humans and the grey collie, and examine the role that mathematical modeling of hematopoietic cell production has played in our understanding  ...  This work was supported by the Natural Sciences and Engineering Research Council (NSERC, Canada) and the Mathematics of Information Technology and Complex Systems (MITACS, Canada).  ...  Much information about the dynamical features of the model can be gleaned from Figure 5 .

Computation as Economics

Bernardo A. Huberman
1997 Social Science Research Network  
This paper describes how computers have evolved to a point where economics approaches are useful for designing them and understanding their dynamics.  ...  Examples are given of existing computer systems that use market mechanisms and of novel phenomena, such as clustered volatility, that we uncovered when studying their evolution. Second  ...  As a result, the system sometimes goes unstable and the equilibrium is punctuated by bursts of activity. the simulation shows that even when the number of agents is large the system exhibits bursts of  ...

Expert-Based Information and Policy Subsystems: A Review and Synthesis

Christopher M. Weible
2008 Policy Studies Journal  
The review begins by summarizing the different uses of information in the multiple streams theory, the punctuated equilibrium theory, the social construction theory, and the advocacy coalition framework  ...  This article synthesizes the findings in a set of propositions about the use of expert-based information in policy subsystems and about the factors that contribute to shifts from one policy subsystem to  ...  From a punctuated equilibrium perspective, the learning use contributes to the accumulation of information and the radical shifts in attention and punctuations in policy.  ...

Explanations of Institutional Change: Reflecting on a "Missing Diagonal"

JOHANNES GERSCHEWSKI
2020 American Political Science Review  
On the other hand, more recent critiques have established a better understanding of endogenous, gradual change.  ...  On one hand, the dualism of path dependency and critical junctures has advanced our understanding of how institutional change occurs due to sudden exogenous shocks.  ...  idea of punctuated equilibrium that follows a step function on the other hand.  ...

Punctuated Process Modelling of Information Systems Development: An Illustration from a Mid-Sized Enterprise

Mike Newman, Shanshan Zhu
2009 Communications of the Association for Information Systems  
Building on previous research, we demonstrate how a punctuated process model can describe and analyze a specific information system development project.  ...  Generally, the combination of these IS research models can provide us with a new, practical and valuable way in understanding Information Systems Development (ISD) as a social process.  ...  Finally, punctuated equilibrium theory is used to understand how change can occur.  ...

Complexity, contingency, and criticality

P. Bak, M. Paczuski
1995 Proceedings of the National Academy of Sciences of the United States of America  
Complexity originates from the tendency of large dynamical systems to organize themselves into a critical state, with avalanches or "punctuations" of all sizes.  ...  The apparent, historical corntingency in many sciences, including geology, biology, and economics, finds a natural interpretation as a self-organized critical phenomenon.  ...  This concept of universality has served well in the study of equilibrium phenomena; in particular, it has been crucial to understanding phase transitions.  ...

Rodrick Wallace, Deborah Wallace
2008 Lecture Notes in Computer Science  
through such means, slower changes induced by selection pressure, triggering punctuated equilibrium Darwinian evolutionary transitions on geologic time scales.  ...  We argue that mesoscale ecosystem resilience shifts akin to sudden phase transitions in physical systems can entrain similarly punctuated events of gene expression on more rapid time scales, and, in part  ...  Thus evolution, resilience, and cognitive phenomena, which can all be (at least crudely) represented by information sources, are inherently subject to punctuated equilibrium phenomena essentially similar  ...
