Before revision:  Disorder is usually associated with contact times between individuals , and normalized contact time values taken from the distribution P(\omega) = 1 / (a\omega) that mimics "face-to-face" experiments.
After revision:  This property, called disorder, is usually associated with contact times between individuals , and normalized contact time values taken from the distribution P(\omega) = 1 / (a\omega) that mimics "face-to-face" experiments.
