Figure 1
The diagram is composed of rectangular boxes connected by directional arrows with hypothesis labels. On the left side, two rectangular boxes are arranged vertically. The top box is labeled “Ethical appeal”, and the bottom box is labeled “Environmental appeal”. In the center, there is a rectangular box labeled “Epistemic value”. One rightward arrow from “Ethical appeal” and another rightward arrow from “Environmental appeal” point to “Epistemic value”. From “Ethical appeal”, a horizontal arrow labeled “H 1” points directly to a rectangular box on the right labeled “Perceived technological improvement and government support”. From “Environmental appeal”, another horizontal arrow labeled “H 2” points directly to the same box labeled “Perceived technological improvement and government support”. A rightward arrow labeled “H 3” connects “Ethical appeal” to “Perceived technological improvement and government support” via “Epistemic value”. Another rightward arrow labeled “H 4” connects “Environmental appeal” to “Perceived technological improvement and government support” via “Epistemic value”.Conceptual framework.
