The diversity within layers (i.e., project activities). (A) Diversity within layers (DW) in five examples of working groups: (A.1) All the participants are from different countries, $\mathrm{DW}=1$. (A.2) One-third of the participants are from USA (blue nodes), another third are from Brazil (green nodes), and the rest are from Mexico (orange nodes), $\mathrm{DW}=0.8$. (A.3) Half of the participants are from Brazil and the other half from USA, $\mathrm{DW}=0.6.$ (A.4) One participant is from Colombia (yellow nodes), the rest are from Mexico, $\mathrm{DW}=0.27.$ (A.5) All the participants are from Brazil, $\mathrm{DW}=0$. (B) The diversity within the SALURBAL Project activities. Each line represents the diversity of each attribute, by project activity. Each bar graph represents the overall diversity within a particular activity, i.e. the average diversity across all attributes. The bars are in order of highest to lowest average diversity of each activity. (C) The ratio of the SALURBAL diversity to the simulated diversity on 1000 randomly generated networks that preserve the degree sequence of the participants' attributes of the SALURBAL network. Each panel represents a project activity and an attribute diversity. The purple indicates a higher diversity than expected by chance. *The p-value < 0.1 indicates that there are significantly more diverse collaborations than expected by chance.
