Measurement in interdisciplinary research: The contributions of widely-defined measurement and portfolio representations

An area of application of measurement with increasing relevance to science and society is interdisciplinary research. Measurement in interdisciplinary research poses new challenges to the theory of measurement, especially when scientists with different disciplinary cultures collaborate. A common framework that allows and invites communication about the process of measurement, including the content and form of the entities under study, is needed. The present paper aims to contribute to such a framework by operational widelydefined measurement and how the portfolio representation of measurement fits within operational widely-defined measurement and supports measurement of the kind of complex attributes often investigated in interdisciplinary research.
