The difference between a substantivist and a relational understanding of ethnic identity

1) Explain the difference between a substantivist and a relational understanding of ethnic identity, making reference to Fredrik Barth. In Barth's model, what is the most prominent location of strong affiliations with ethnicity? 2) What do anthropologists mean when they say that race is "socially constructed"? 3) What are the unintended consequences of humanitarianism? Give at least two examples. 4) Define "technomoral" and elaborate on how an understanding of technomoral politics expands what counts as humanitarian work.
