Distinguishing between conceptual and empirical was less meaningful for the papers that were purposively sampled to fill conceptual gaps, as all of them were sampled because it was known by members of the research team that they had important theoretical concepts to offer. Papers sampled purposively and coded above as “empirical” are those that rely primarily on a clearly defined policy case or cases to develop, illustrate, and support their theoretical arguments.
