Most databases include some – but not all – articles in Full Text (which means you can open the entire article right in the database). See the bottom result, which has the Full Text PDF icon circled. By clicking on this icon, you would open the entire article.
When the Full Text is not available, you need to click on UC eLinks as in the top result. This will generate a search in all of the databases UCSD subscribes to, to hopefully find another database with the full-text.
