2014 theme, asides only in widget column

Hello!

Hi guys, I have 3 columns on my page, left menu, middle where the main posts are, and a small right column.

On the right column the Asides show up when they are posted on the main. Is there a way to make them show up only on the right column?? I don’t really want little tiny posts to populate the centre where the bigger posts are.

Kind of how it is in the demo page

Many thanks.
