The European Union proposed a new model of economy, at this beginningof century and millennium: the economy of knowledge, simultaneous with the emergenceof a new existential reality for us people, after Christ was born; this new, existentialreality are the climatic changes.In spite of the warning signals drawn by specialists, the more profound conquests ofscience, only a new educational model can save the humankind of a galloping fall inpromiscuity but also in eternity.economy of knowledge, educational model, cohesion policy, changes

On the heapability of finite partial orders

We investigate the partitioning of partial orders into a minimal number of heapable subsets. We prove a characterization result reminiscent of the proof of Dilworth's theorem, which yields as a byproduct a flow-based algorithm for computing such a minimal decomposition. On the other hand, in the particular case of sets and sequences of intervals we prove that this minimal decomposition can be computed by a simple greedy-type algorithm. The paper ends with a couple of open problems related to the analog of the Ulam-Hammersley problem for decompositions of sets and sequences of random intervals into heapable sets
