In refraction seismology as well as in global seismology we often find travel-time diagrams where reduced time is used. In principle this means that the refraction arrival of interest is approximately horizontal in the travel-time diagram. This can be achieved by doing the following transformation red red v t t ∆ =− (14)

Promoting Ethics in the Public Service

Programme is advised by a Group of Experts, which meets biennially and reports to the Economic and Social Council and ultimately the General Assembly. In 1996, the General Assembly adopted resolution 50/225 on Public Administration and Development. This resolution broadly confirmed the vital importance of governance, public
