This inclusiveness leads to certain definitional ambiguity (albeit one derived from the term culture itself). This definitional discrepancy may explain some of the disagreement among researchers. The classical theory of concepts says that concepts have a definitional structure. Regulations require a definitional distinction between non-natives that are deemed especially onerous and all others. Differing analyses of the Catholic relationship to science may arise from definitional variance. Such an approach poses significant definitional issues. Some sources claim that this is justified by the blurring of definitional boundaries in Japan. Our world is a product of continuous "claims making, labelling and other constitutive definitional processes". Addressing these issues produces the more general notion of a "definitional interpreter". These definitional issues are potentially severe for practitioners. These definitional issues can become very complex. The proceedings of this definitional meeting were published in 1990 as the book "Computational Neuroscience". In "Globalization and Belonging", Sheila L. Crouche discusses "The Definitional Dilemma". By addressing definitional issues as a first step, the Board will facilitate continued cooperation. In its modern form, the quantity theory builds upon the following definitional relationship.
