A dot encircled means the direction of magnetic or electric field directeed upwards perpendicularly out of the plane of the paper, where as a cross encircled means just the opposite, i.e. directed inside the plane of the paper.
This concept is more or less used to describe the direction of any typ of flow of field direction.
