The ubiquity of jet phenomena in young stellar objects, active galactic nuclei, symbiotic stars, planetary nebulae and x-ray binaries has driven a broad literature on the astrophysics of collimated mass ejection. One of the fundamental open problems in star formation is the understanding of the physical mechanisms by which mass is ejected from the protostellar system and collimated into jets. Locally jets will regulate the system angular momentum and therefore its evolution during the first few million years. At large scale jets inject momentum into the cloud thus affecting its star formation efficiency and evolution. Many recent advances over the last years in the star formation field in both theoretical and observational aspects together with the increasing availability of computational resources, conveyed for a perfect opportunity to organize a workshop to discuss the jet phenomenon at different astrophysical scales, covering interdisciplinary areas such as steady state winds, time-dependent winds/jets, jet energetics and jet/wind propagation.
