Similarities in the Berlo, Universal Communication System, Shannon/Weaver, and Emmer/Donaghy model are; sender, receiver, noise, channel, message, and feedback. However, I did find that feedback isn't actually written in the Berlo model, but it may be assumed since the the sender and receiver are defined as the same.
The model that I created focuses on the duality of this concept. The idea of how does the message get from point A to point B? Encompassing this linear transition is the over-arching concept of feedback from the two sources back and forth to each other.
