Communications The CYD provides regular communications regarding its research, evaluation, education, and training activities. Audiences for these communications include UC Cooperative Extension professionals, UC campus-based scientists, other youth professionals, scientists from other institutions, youth program volunteers, youth, community agencies, stakeholders, and decision-makers. The Update includes news on initiatives and projects of the 4-H CYD and updates relating to research for county-based professionals. A profile of a selected faculty member was introduced in the Winter 1999 issue and has been included in various subsequent issues.
