Identify the title of the journal from your reference and the volume, year and pages the article is on. Searching library catalogues by Title is the best way to locate a journal. Librarians can help you. Look at your spelling again. Perhaps your topic is too recent for a database search.
Databases take a while to catch up with journals.
Start with very specific terms and broaden them if necessary. Check a Thesaurus or the online Index of the database. This lists all subject headings used to categorise articles in the database. This was a huge Trek, but an important one. You can also link to Step by Step Guides to database searching for practice.
