NIEM domains are organized to facilitate governance, and each has some measure of persistency. The persistency was selected to optimally match the nominal maximum frame rate. Transfluthrin is a fast-acting pyrethroid insecticide with low persistency. Esping-Andersen traces in this persistency the origins of the chronically high Italian unemployment rates. However, none of them have both persistency and indications of dynamic motion. Data persistency is routinely 5% while video persistency can easily reach 50%.
