Theoretical HR calculated from the individual's corneal curvature and AC depth can be used in lieu of the empirical HR for gaze position calibration to within approximately 2 degrees/mm of accuracy. Gaze position accuracy significantly improves by using the theoretical HR, relative to the population-average HR. Corneal curvature and AC depth combined explain the majority of intersubject variability in HR.

An online survey was developed to map Extension's presence in divorce education initiatives and to catalogue the amount, type, and availability of resources that each state has dedicated to meeting the needs of this parent audience. Requests for participation were sent to members on the National Extension Human Service listserv and resulted in representation from 48 out of 50 states and one U. S. territory. Results document a national presence, outline the nature and expression of Extension divorce education programs, and suggest a direction for future collaboration related to this topic.
