Diffusion of behavior in dynamic networks
König, Michael D. - 2017
We analyze binary choice models in communication networks, in which both, the formation of links in the network as well as the action choices are endogenous. We provide a complete characterization of the equilibrium action choices and networks, where agents choose their strategies - actions and...

THE SPATIAL AND TEMPORAL DIFFUSION OF STYLISTIC INNOVATIONS IN MATERIAL CULTURE
SCHOLNICK, JONATHAN B. - In: Advances in Complex Systems (ACS) 15 (2012) 01, pp. 1150010-1
Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have … underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their … among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural …

DYNAMIC BEHAVIOR OF A NONLINEAR SINGLE SPECIES DIFFUSIVE SYSTEM
CHEN, FENGDE; CHEN, XIAOXING; SHI, JINLIN - In: Advances in Complex Systems (ACS) 08 (2005) 04, pp. 399-417
In this paper, we consider the following nonlinear single species diffusive system \begin{eqnarray*} \dot{x}_i(t)&=& x_i(t)\left(b_i(t)-\sum_{k=1}^{l_i}a_{ik}(t)(x_i(t))^{\beta_{ik}}\right)\\ && +\,\sum_{j=1}^{n}D_{ij}(t)(x_j(t)-x_i(t)),\quad (i,j=1,2,\ldots,n), \end{eqnarray*} where bi(t),...

DO LANGUAGE CHANGE RATES DEPEND ON POPULATION SIZE?
WICHMANN, SØREN; STAUFFER, DIETRICH; SCHULZE, CHRISTIAN; … - In: Advances in Complex Systems (ACS) 11 (2008) 03, pp. 357-369
An earlier study [24] concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets. We replicate this study using a more complete language model for simulations (the Schulze model combined with a...

BETTER BEING THIRD THAN SECOND IN A SEARCH FOR A MAJORITY OPINION
STAUFFER, DIETRICH - In: Advances in Complex Systems (ACS) 05 (2002) 01, pp. 97-100
Monte Carlo simulations of a Sznajd model show that if a near-consensus is formed out of four initially equally widespread opinions, the one which at intermediate times is second in the number of adherents usually loses out against the third-placed opinion.

Evolution and depression
Wittman, Donald; Singh, Nirvikar - 2012
The standard evolutionary explanation for depression is that being emotionally depressed is adaptive. We argue that being depressed is not adaptive (indeed, quite the opposite), but that the threat of depression for bad outcomes and the promise of pleasure for good outcomes are adaptive because...
