Restrictions on Multiple Presentations

  • Regardless of the presentation format—such as symposium, workshop, oral, or poster presentation, each participant is allowed to give only one presentation with abstract (*).
    • It is NOT permitted to be a presenter in both a workshop and a regular presentation at this meeting.
    • This restriction applies only for being a presenter. There are no restrictions for being a co-presenter (co-author). Presentations given in forums, which are events organized by ESJ committees, are not subject to this restriction.
  • All presentations requiring abstract registration (*), except for poster presentations, must be delivered on-site. However, this requirement does not apply in cases of reasonable accommodation.
  • In addition to the above presentations with abstract, it is possible to give contributions that do not require the submission of a presentation abstract (*), such as general introductions, commentators, panelists, or lightning talks, or to organize a session only.
    • Please note that symposia and oral presentations may be scheduled in the same time slot. Even if presentation times overlap, no adjustments will be made to the presentation schedule. We kindly ask for your understanding that we will not be able to accommodate individual requests.
    • For workshops, considering their diverse formats, they are scheduled so as not to overlap with symposia and oral presentations.
  • Each participant may organize only one session, except for forums. It is not permitted to register as an organizer for multiple sessions.

* The basis for this restriction is the “presentation abstract” registered by each presenter. If the organizer of a session does not register as a “presentation” at the time of application and only provides information in the “session abstract,” such presentations are not subject to the above restriction.

Presentation Eligibility by Membership Type

Only ESJ members (regular, student and emeritus members) are eligible to be presenters (primary author) at the meeting. Non-members are eligible to present in the following three cases:

  • As an invited speaker in a symposium (Symposium Invited Speaker Program).
  • Contributions in a symposium or workshop that does not require the submission of a presentation abstract, for example, general introductions, commentators, panelists, lightning talks, etc.
  • High school students and younger presenting in the Junior Poster Session.

Co-presenters are not required to be members.
