I love the message in this tutorial about modeling the behavior that you want to see in others. We have a professionalism initiative currently in place at my school. One of the most difficult challenges is trying to get all faculty to model the apporpriate behavior--getting to the class 15 minutes early and being the last to leave, getting assignments grade in a timely manner etc. This is a great reminder to all that you are being watched wether you know it or not. Always hold yourself to the highest expectations, and others will follow.
