These are publications that are published in Open Access (OA) via the green route.

The articles are not always freely accessible, but you can ask the author for a copy via the platform. You do have to log in, either via Google or Facebook, or by creating an account. Researchgate is mainly a platform of collaboration for researches, whereas Academia.edu is more often used to share articles. 
 
Through the library
Please contact the library of your institution if you are still unable to find the full text after using the mentioned tips and tools. The information specialists will be happy to see if there is a faster and/or cheaper option than buying a copy from the publisher.
