A study is a group of users working together to more easily access data. On the studies tab of the administrator panel you can view all studies which contain your organization's datasets. You can't edit any study from this panel.
When users submit study requirements they will appear here. You can approve or reject them, or leave a comment for the study's members.
If you approve a study requirement, all collaborators on this study now and in the future will be approved for that requirement.
