Phase Transitions in Paradigm Shift Models
Two general models for paradigm shifts, deterministic propagation model (DM) and stochastic propagation model (SM), are proposed to describe paradigm shifts and the adoption of new technological levels. By defining the order parameter m based on the diversity of ideas, Δ, it is studied when and how the phase transition or the disappearance of a dominant paradigm occurs as a cost C in DM or an i...
متن کاملModels of Social Phase Transitions
Social phenomena can exhibit drastic changes with small changes in external parameters––phase transitions. Furthermore, physical models can be applied to social systems because most of the small details can be ignored just as in physical systems. Many models have been used and developed, most notable network models. However empirical data and their interpretation are not yet good enough to make...
متن کاملNUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
متن کاملPhase transitions in models of human cooperation
a r t i c l e i n f o a b s t r a c t If only the fittest survive, why should one cooperate? Why should one sacrifice personal benefits for the common good? Recent research indicates that a comprehensive answer to such questions requires that we look beyond the individual and focus on the collective behavior that emerges as a result of the interactions among individuals, groups, and societies. ...
متن کاملParadigm Shift
A paradigm shift, suggested by Thomas Kuhn [1], is not just a small change in science, or the modification of a theory. It is a scientific revolution and completely changes the way in which science looks at the world. It often dictates how the public looks at the world. For example, Darwin's theories [2] were intensely debated by scientists and theologians. This debate spilled over into the pub...
