The writer of this article, which is very good, should have used the abbreviation DoEd or DoED instead of DOE which stands for the Dept. of Energy.
A minor point but if you search for DOE you might get the Energy listings first.
My family has members who work at DOE, DHS and DOJ (and parents who worked at DOD/Dept. of the Army - CWS, ASA, etc). We call ourselves the “America Protecting Alphabetical Soup Club” = (4 wars, 4 veterans, two elderly parents now deceased - DOA (Army) WW2 etc) and one Vietnam journalist). We all like alphabet soup!
