“…More recently, Integrative Propositional Analysis (IPA) has emerged as a useful method for rigorously and objectively analysing the systemic structure of conceptual systems such as models, theories, and strategic plans. A number of publications attest to the usefulness of IPA including applying for and assessing research grants (e.g., Cotae, ), learning (Goltz, ; Russell & Wallis, ), finding the core of theories (Wallis, ), explorations into the limits of our thinking (Wallis & Valentinov, , ), integrating theories within and between disciplines (Wallis, ), understanding and improving theories (Wallis, ), assessing and improving policy (Shackelford, ), interdisciplinary studies (Wallis, , ), developing more sustainable theories (Wallis & Valentinov, ), programme evaluation (Houston, Wright, & Wallis, ; Wright & Wallis, ), and strategic knowledge mapping (Wallis & Frese, ; Wallis & Wright, ).…”
