Amplitude chimeras and chimera death in dynamical networks

We find chimera states with respect to amplitude dynamics in a network of Stuart-Landau oscillators. These partially coherent and partially incoherent spatio-temporal patterns appear due to the interplay of nonlocal network topology and symmetry-breaking coupling. As the coupling range is increased, the oscillations are quenched, amplitude chimeras disappear and the network enters a symmetry-breaking stationary state. This particular regime is a novel pattern which we call chimera death. It is characterized by the coexistence of spatially coherent and incoherent inhomogeneous steady states and therefore combines the features of chimera state and oscillation death. Additionally, we show two different transition scenarios from amplitude chimera to chimera death. Moreover, for amplitude chimeras we uncover the mechanism of transition towards in-phase synchronized regime and discuss the role of initial conditions

"Why Is Economics Not an Evolutionary Science?" New Answers to Veblen's Old Question

Addressing the question why Economics as a discipline is not subject to evolutive processes itself, we explain the paradigmatical dominance of neoclassical theories in Economics as a path dependent process. Recognizing economics as "locked into neoclassical thinking," we first identify three positive feedback mechanisms leading to strong barriers to paradigmatic change: coordination, complementarity, and learning mechanisms. In a second step, we show how actors strategically enforce these mechanisms via distinct "amplifiers." We then try to use this theoretical perspective to cursorily describe potentially path-breaking strategies
