Ecological knowledge shrinks as economies grow

Do all economies grow equally fast?

The stochastic spatially extended generalized Lokta-Volterra approach introduced in Solomon [48], Challet et al. [18], Yaari et al. [58], is extended to the study of interactions between economic sectors, countries and blocks. The theory predicts robustly in a very wide range of conditions systematic regularities in the growth rates evolution of various subsystems. The J-curve phenomenon which ...

Sustainable ecological economies

A brief accounting is presented of the evolution of natural ecosystems and human cultures including industrialization and its ecologically-significant interactions with natural abiotic and biotic processes of the earth. These accounts show, among other things, that excess resource harvest rates and material releases into the natural environment have been ecological risks of growing scope and sc...

Time to retool as CABG volume shrinks.

shrinks even small worlds

We consider small world graphs as defined by Kleinberg (2000), i.e., graphs obtained from a ddimensional mesh by adding links chosen at random according to the d-harmonic distribution. In these graphs, greedy routing performs in O(log2 n) expected number of steps. We introduce indirect-greedy routing. We show that giving O(log2 n) bits of topological awareness per node enables indirect-greedy r...
