Research Hub does not exits; it needs to be written and added
From http://hub.berkeley.edu/about/: Introducing the Research Hub:
Manage and Share Your Scholarly Materials
The Research Hub provides an easy way for campus scholars to gather, organize and share their digital files, such as office documents, images, audio, video, and PDFs. The Research Hub helps you work with colleagues, co-authors and project team members by providing powerful collaborative tools, including blogs, wikis, document libraries, discussion forums and more.
