Figure 1
The conceptual framework shows a left-to-right layout with three main rectangular boxes and a separate panel for control variables. On the far left is a large rectangle labeled “B G D”. On the far right is a large rectangle labeled “E M”. Two horizontal arrows point from the B G D box to the E M box. The upper arrow is labeled “H 1 a” above the line and “R D T slash S R T” near the arrow. The lower arrow is labeled “H 1 b” above the line and “G T T” near the arrow. Below the center of the diagram is a smaller rectangle labeled “E S G”. Inside this rectangle is the text “H 2 (as moderator)”. A diagonal arrow extends from the B G D box downward toward the E S G box. Another diagonal arrow extends upward from the E S G box toward the E M box. On the far right side of the diagram is a separate rectangular panel labeled “Control Variables”, followed by a vertical list of text items: “Board Size”, “S I Z E”, “L E V”, “I N V”, “R O A”, “Z S C O R E”, and “G R O W T H”.Conceptual framework
