Information for Presenters, Discussants, and Chairs:

Check-in will be open at 3:30 pm on Friday, April 21 for all registered participants at the Capital Terrace on the 2nd floor of the Capital Hilton.

We do ask that presenters bring their presentation on a USB flash drive. There will be a laptop pc in every session room. Wifi will also be available in the lobby areas and in the session rooms.

The Rising Stars sessions on Friday evening are 90 minutes with 3 papers, allowing 30 minutes per paper. The time should be divided 22 minutes for the presenter, 5 minutes for the discussant, and 3 for audience comments.

The Saturday and Sunday sessions are 120 minutes long with four papers or three papers. That allows 30 minutes per paper, which should be divided 22 minutes for the presenter and 5 minutes for the discussant and 3 for audience comments. A few of the longer sessions have 5 papers and there the time is reduced to 24 minutes per paper, divided 18 for the presenter, 5 for the discussant, and 1 minute for audience comments. The session chair is usually the last presenter or discussant in the session and is in charge of keeping the session running on schedule.

Papers should be uploaded to the IIOC Conference Maker site so the discussants can prepare their comments.

Please check occasionally to see if the details for your sessions have changed.
