can’t get access to supplementary data

Hi everyone! I’m new at this but I’m in desperate need of the document with supplementary data from this paper: [https://www.sciencedirect.com/science/article/abs/pii/S0043135415302943](https://www.sciencedirect.com/science/article/abs/pii/S0043135415302943)

Anyone knows how to get it?

Thanks!
