Recording of Alexander Gabrys' Eco-Ethno-Polish-Mountains-Music-Spheroid. This work is composed of four parts on acoustic material borrowed from recordings of authentic Polish mountain folklore. Despite a very advanced technical and sound transformation, the nature of folklore is highlighting its dynamic character. The sound developed from: "gajdy" (bagpipes), "krzapoki" (goat bells), shepherd's horn, Polish violin, and by a pseudo instrument composed of a kind of whip used to flagellate horses.

This article considers an analogous problem in which the observed random variables are the steps of a symmetric random walk. Assuming continuously distributed step sizes, it describes the optimal stopping rules for the cases n = 2 and n = 3 in two versions of the problem: a "full information" version in which the actual steps of the random walk are disclosed to the decision maker; and a "partial information" version in which only the relative ranks of the positions taken by the random walk are observed. When n = 3, the optimal rule and expected rank depend on the distribution of the step sizes. The authors give sharp bounds for the optimal expected rank in the partial information version, and fairly sharp bounds in the full information version.
