Chairs of parallel sessions are asked to:

1. Introduce each speaker very briefly: Name, Affiliation, Title of Talk.

2. Keep time. With transitions and Q&A, each speaker is likely to have 22-23 minutes to talk.  Please make signs or use a tablet to signal to each speaker the remaining minutes for the presentation preceding the Q&A: e.g. 5 minutes, 3 minutes, 1 minute, stop.

3. Instruct speakers to disconnect technology before their Q&A begins; the next speaker, unbidden but perhaps with a reminder from the chair if needed, should come to the front promptly at the beginning of the previous speaker's Q&A to set up presentation technology (if any), so that as little time as possible will be exhausted on tech fiddles during transitions. Speakers are asked to rehearse their technology in advance of the conference to iron out wrinkles.

4. Alert student tech assistants to problems.

5. Check at the beginning of the session that student help has supplied water.
