Based on the following dataset, the attached graphs aim to test the potential influence of contributions' educational background (the academic disipline in which they graduated) on the number of articles they contributed to the Chinese Economic Monthly/Journal, in relation to the range of topics they addressed (number of distinct topics, on a scale ranging from 1 to 7), all periods included (1) and per period (2). We relied on R package "ggplot2" to build the scattered plots.
