Thank you for agreeing to serve as a Session Chair for CEC/ICMC 2019. The following describes the details and specifics for managing sessions at the 2019 conference. These guidelines encompass policies set forth by both conferences as well as editorial policies enforced for publication of the proceedings.

  • All CEC/ICMC 2019 sessions will have two Session Chairs.
  • Session Chairs are responsible for reviewer recommendations.
  • There are four types of sessions; plenary sessions, focus sessions, regular oral sessions, and poster sessions.
  • Session Chairs must complete the Session Chair Report after the session and return it to the Publication Office (Room 11).
  • For focus and oral sessions, the blank Chair Report will be placed onto the speaker podium prior to the session in the session room(s).  
  • For poster sessions, please go to the Publication Office (Room 11) to pick up your blank Chair Report. 
  • If a scheduled presentation has no-show presenters and the presentation has to be canceled (e.g. was not given), the corresponding paper, if submitted, will not be considered for peer review and published with IOP Conference Series: Materials Science and Engineering (MSE), Advances in Cryogenic Engineering.

Session Chairs for ORAL SESSIONS have several responsibilities.

Prior to the session start:

  • Please read over all abstracts in your session before the day of the session.
  • Please go to the Speaker Ready Room (Room 11) prior to the session to check whether all presentations have been submitted. Talks will be pre-loaded to the computer in your session room. It is also a good idea to confirm which talks are loaded on the computer just prior to the start of the session.
  • Take 5 – 10 minutes prior to the session to familiarize yourself with lighting controls, computer, laser pointer, slide controls, microphones, and the general layout of the room (viewing angles, doors, noise, etc).
  • If there are any issues, please advise the conference staff.
  • Take a roll-call of all speakers.
  • PowerPoint tip: F5 will start the presentation, ESC exits.
  • Acrobat tip: Ctrl – L will enter full-screen mode, ESC exits.

Beginning of and during sessions:

  • Announce the title of the session.
  • Introduce yourselves.
  • Explain the ground rules:
    • Invited oral = 25 min (warn at 23) + 5 min for questions. Contributed oral = 12 min (warn at 10) + 3 min for questions.
  • You should introduce the presenting author and the title of each presentation.
  • Be polite but firm when enforcing these guidelines: Stand, ask the speaker to conclude. Keep control of the session time!
  • At your discretion, talks may encroach into question time, but then you should defer questions to private discussion.
  • Monitor noise, audience, etc.
  • The two chairs can alternate this task.
  • Every presentation must be exactly as scheduled. If a speaker does not show on time for his/her presentation, the next speaker shall not begin the presentation until the scheduled time. Session Chairs may fill the time before the next presentation starts by allowing more questions or initiating discussion on the subject of the session.
  • Complete and return the Session Chair Report. Check off presentations as they are given. Also estimate the audience size. This information must be returned to the Publication Office (Room 11).
  • PLEASE! Do not let anyone walk away with the laser pointer!


POSTER SESSIONS do not require introduction of the authors or of the presentations.

  • Session Chairs are asked to record any posters that were not presented. One of the authors must be present at most, if not all, times with the poster presentation.
  • Walk the session multiple times. Note that in some cases, an author may need to attend to more than one poster, and thus might not be present during your first survey, so you may have to return later. Poster presenters have been instructed by Conference Management to leave a note on their posters to say when they will return. Feel free to remind the attendees of this request.
  • Complete and return the Session Chair Report to the Publication Office (Room 11). Record posters that have been mounted and are attended by a presenter, posters mounted but have no attendant, and posters that are missing entirely (No-Show column). Please take note of the policies that follow when completing this form. Estimate audience size.
    • Poster policy #1: If a poster is placed on the poster board but an author is not available for the entirety of the session, this is not considered as having been presented. Please make a note on the session Chair Report in the No-Show column.
    • Poster policy #2: Posters that simply consist of a posted copy of the paper (even if enlarged) are not considered to be poster presentations. Please mark the poster as a No-Show in the Session Chair Report.

If you are unable to drop off the session chair report by 11:45 a.m. on Thursday, July 25, please email the completed report to Centennial Conferences or fax it to [001] 303-499-2599.


Guidelines for Initiation of the Peer Review Process

Session chairs are also key to the peer review process.

  • Each session chair is responsible for identifying and confirming reviewers to the papers in their assigned session.
  • It is perfectly acceptable for a session chair to assign the papers to him- or herself, provided there is no conflict of interest (as for co-authors and referees with the same affiliation). There are many session chairs that prefer to review all the papers in their sessions. If you choose to accept your role as default reviewer, please notify the publication office by the deadline below.
  • In seeking reviewers, each chair should find 1 reviewer for each paper they do not wish to review themselves. Publication guidelines recommend that chairs not try to divide the referee assignment work in any other way.
  • DEADLINE: Please submit your list of reviewers with their email addresses and the papers they are to review to the staff in the Publication Office (Room 11) by 5:00 p.m. Hartford time on Wednesday, July 24, 2019.  Sessions chairs that do not provide a response will become the reviewers for these papers by default.
  • If circumstances arise and you cannot fulfill your responsibilities, you have the obligation to notify the conference organizers.

If you have any questions or need additional information, please contact Centennial Conferences by email.
