Answer
If you go to the OU portal and login to http://myottawa.ottawa.edu go to the Myers Library Online page. Click on the Online databases page and go to Ebscohost. In Ebscohost select the following databases Academic Search Premier, Social Science Index Full-Text, PsychArticles and Regional Business News by making a checkmark next to them and after choosing them click on the "continue" button. In the search box that comes up, make sure you choose AND to combine your search. You also will want to choose the limiters below the search box and check the full-text and peer reviewed articles(scholarly articles) boxes and try the following searches. I tried them in Ebscohost and so you can replicate them:
Use these search terms
death penalty AND United states
death penalty AND Europe
death penalty AND Asia
death penalty AND Africa
death penalty AND Latin America
