Cosmopolitan communication is learnable, teachable and contagious, where might you go to learn this art?

Answer 1

From "A First Look at Communication Theory" (McGraw Hill website):

"cosmopolitan communicators According to CMM, people who intentionally converse in a socially eloquent way that promotes respectful dialogue and coordination (see also dialogic communication)."

I would assume that a well-prepared Communication Theory course at a University would teach this, or other types of "How to Communicate more effectively" course that are often available to corporations, etc. for employees.

Hope this helps!
