About Poster Flash Talks

・All sessions with poster presentations are required to have a poster presentation flash talk frame during the designated time in the oral session.

・We will only list the flash talk frame as "Flash Talk" without any specific information in the program, so you don't need to work on it using the system. However, if you wish any adjustment listed below, please contact JpGU Office as it needs to be reflected on the system.

・All sessions with poster presentations will have the same number of Flash Talk frames as oral slots. One 15-minute Flash Talk frame will be initially set up for each oral slot. However, to meet as many needs as possible for variety of sessions, the below adjustment can be requested.

・The Flash Talks for sessions without oral presentations will be held in a hybrid format, with a separate date and time (between AM1 and PM2) to be determined by the Program Committee. On-site venue will be provided, so you can make a presentation either on-site or online.

【Coordination of the content and the possible adjustment to Flash Talk frame】

・The minimum presentation time for a Flash Talk is one minute, and the maximum number of presentations allowed in one frame (15 minutes) is 9. As long as it is within the rule, the presentation time and number of presentations can be freely decided by the conveners.

・The duration of one flash talk frame is fixed to 15 minutes and this cannot be changed but there is no limit on the number of flash talk frames allowed in one oral slot. If multiple oral session slots are allocated and there are multiple Flash Talk frames, it is possible to move the Flash Talk frame to another slot and hold them together.

・ A Flash Talk frame will be allocated for each oral slot, but if you need more frames, the time allocated for oral presentations can be changed to additional Flash Talk frames.

・It is also possible to move the flash talk frame to the beginning of the session.

【Presentation material for the flash talk 】

・Poster presenters must upload the e-poster on the participation website "Confit" and use it as their presentation material for the poster flash talk.

【Announcement of the content of flash talks】

・We kindly ask the conveners and chairpersons to inform the presenters of the order, time, and method of presentation of their flash talks by using the session mailing lists. The mailing list will become available from late March or early April.

Introduction of Diversity Promotion Logo

JpGU has been working on the promotion of diversity and has introduced a logo to visualize the diversity of the session conveners since 2021.
At JpGU 2024, we plan to keep this promotion by using a gold-based logo for sessions that meet three of the following criteria: multiple genders (especially female), multiple career stages (early career researchers up to seven years after obtaining a degree), and multiple nationalities (whether foreign researchers are included), and a silver-based logo for sessions that meet two of these criteria.
We would appreciate it if you could take this into consideration as much as possible when selecting conveners.

How to apply
