    —Require conceptual definitions of key concepts

    —Can be represented in a schematic model

    —Are created by humans

    —Are developed inductively

    —Cannot be proven—they are supported to greater or lesser degrees

    —Can be used to generate hypotheses

    —Can serve as a stimulus to research
