  In this study, we track and analyze publication downloads from both
copyrighted and pirated platforms to reconstruct scientists' activity patterns
from a holistic perspective. Scientists around the world are working overtime,
but scientists in different countries have different working patterns.
Scientists' preferences for different platforms are influenced by a variety of
factors such as working times and workplace arrangements. There are variations
by country in terms of whether scientists prefer to work overtime at night, at
the weekend, or both at night and on the weekend. When scientists are working
overtime, they prefer to use Sci-Hub rather than copyrighted platforms to
access scholarly publications This may be because of the transition in their
working scenarios as they move from the office to home outside of work hours.
