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),...

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...

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.

<Para ID="Par1">This paper argues that an evolutionary approach to policy-making, which emphasizes openness to change and political variety, is particularly compatible with the central tenets of classical liberalism. The chief reasons are that classical liberalism acknowledges the ubiquity of uncertainty, as...</para>

Technological artifacts such as software often comprise a large number of modules; more than twenty thousand in the case of the Java software Eclipse. While on the micro-level this system is modular, how should the building blocks be arranged on the macro-level? In the literature this question...
