Lines 60-71: each affiliation property is set using a 2-step assignment, e.g.
```
department = get_author_department(article_id, author_id)
affiliation.department = department
```
As ```department``` is only used once, for the assignment to affiliation, this could be more efficiently achieved with:
```
affiliation.department = get_author_department(article_id, author_id)
```
which I think is just as readable.

Ditto for the other affiliation properties
