Figure 1
The diagram shows four rectangles on the left, arranged vertically from top to bottom labeled “Parental leave”, “Income”, “Education”, and “Age”. Three rectangles are positioned on the right, arranged vertically from top to bottom labeled “Economic motivation”, “Sustainability motivation”, and “Parenting motivation”. Multiple diagonal lines extend from each left-side rectangle toward all three right-side rectangles. Along these lines, small circles display symbols indicating direction of relationship, including “plus”, “minus”, and “plus or minus”. From “Parental leave”, three diagonal lines extend toward “Economic motivation”, “Sustainability motivation”, and “Parenting motivation”, each marked with “plus”. From “Income”, three diagonal lines extend toward the three right-side rectangles, marked with “minus”, “plus”, and “plus or minus”. From “Education”, three diagonal lines extend toward the three right-side rectangles, marked with “minus”, “plus”, and “plus or minus”. From “Age”, three diagonal lines extend toward “Economic motivation”, “Sustainability motivation”, and “Parenting motivation”, each marked with “minus”.The hypotheses.
