In this paper we show what is the precise expressive power of T-stable models when uniqueness is required , i.e ., a query give an answer if and only if there exists a unique T-stable model . However , the Kansas statute is more limited than federal law with respect to the circumstances under which reporting is required , i.e ., only when there is reasonable cause to believe that abuse has occurred , as opposed to when abuse has merely been alleged . According to this view , the IA model plays the role of ensuring consistency and points to substantive areas where more information is required , i.e ., researchers use the model as a guiding tool for research prioritization . Many licenses may be purchased for immediate use except where tagging is required , i.e ., deer and turkey .
