[2] In three separate terms spanning 17 years, from 1966 to 1985, Quebral served as the chairperson of the various earlier incarnations of what later became the CDC, where her colleagues referred to her by her initials, "NCQ".
In 1971, she delivered her paper Development Communication in the Agricultural Context at a UPCA symposium in honor of its outgoing dean, Dioscoro L. Umali.
Drawing from the works of Alan Chalkley, Wilbur Schramm, and Daniel Lerner, among others, she coined a definition of the field outlining its basic theory and practice.
[3] In that paper she noted that: The reason for my having to coin my own definition is that development communication is still very much in the evolutionary stage so that no one is quite prepared to be pinned down to an exact definition of it.The UP College of Agriculture was declared an autonomous unit of the University of the Philippines system the following year, 1972, and was reborn as the University of the Philippines Los Baños (UPLB).
She set up the Nora C. Quebral Development Communication Center, Inc. (NCQDCCI) and focused on professional practice and research.
