The list on the right side of your dashboard is a list that references new activities/items since your last log in: these blue links in the top right let you quickly get to items that need your attention (e.g. Signatures) or that you may have missed (e.g. newly assigned audits). Not all items require you take action, some are just informative notifications.
To review these items simply click on the links, and the actions/items will populate below.
If the Action requires action (Signatures Needed) you will see , which you can execute right from here.
