What is a PSS? How are PSS defined? How did the definition of PSS change throguh the years?
Here below you find a link to the PSS Chart developed by our colleagues at Denmark Technical University. The Chart provides an overview of the stabilization of PSS definitions within PSS research, by presenting the most prominent ones and their interrelationships.The research was developed by Ronja P. Haase, in the context of a Special Course at the Technical University of Denmark and was supervised by Prof. Tim C. McAloone and Daniela C. A. Pigosso.
The chart maps 56 prominent definitions and graphically illustartes the citation relations between them. Eleven common characteristics among these definitins are further identified.
