Although they meet the required theoretical requisites (soundness, completeness, etc).
Also, the findings that relate to each method will be used to complement one another and, at the end of the study, to enhance theoretical or substantive completeness (Ausubel 1968).
These interests are of two types, and include theoretical goals of achieving completeness and systematic unity of knowledge, and practical interests in securing the immortality of the soul, freedom, and the existence of God.
A formal specification of the meaning of a term using an ontology can be accompanied by a meta-theoretical analysis and a completeness proof for the ontology [ 105].
Theoretical backing stems from the proven completeness of the method for a large category of diverse environments.
The validity of the theoretical framework depends mainly on the completeness of the relevant criteria.
The question of how completeness results (and other model-theoretical properties) can be transferred from a propositional modal logic to its quantificational counterpart, and from a monomodal quantified modal logic to their multimodal combinations by means of fusion, is investigated in Schurz 2010.
In the last two decades a great experimental effort together with some theoretical knowledge have been employed to investigate the completeness and consistency of knowledge-based systems and to clarify the structure of these systems.
For completeness of the review, in this section we outline theoretical works underpinning the use of gamification in education, published within the review period.
