An almost strong relation

We prove an almost strong polarized relation at successors of strong limit singular cardinals, based on the assumption that $2^\mu>\mu^+$. This relation is preserved by the collapse of $2^\mu$ to $\mu^+$, and then it becomes optimal

Cartoons and economics: general analysis based on colombian economic cartoons.

May cartoons be considered as a viable and credible source for the study of economics? There is hardly any research on the subject, even though there is a quite significant amount of cartoons with economic content. This suggests that economics (and economists) have not paid enough attention and do not incorporate in their analysis a relevant primary source. The present paper aims to explore the value of using cartoons as a complementary primary source in economic analysis. We present a way of analyzing economic history through cartoons; first, reviewing cartoons which describe particular historical circumstances and second, examining cartoons that represent generic economic situations and are not necessarily linked to a historical period. We choose 17 cartoons, from different cartoonist, especially Colombian cartoonists that may give us an idea of economic matters and economic history.Cartoons, economic history, Colombia, economic cartoon
