  • How do I find out what to do as a presider (aka moderator, session chair) for my session?

    Virtual session Presiders will have a very similar role to what they would in an in-person meeting. They must register for the meeting, log-in to the session early, verify presentation order, greet the speakers, introduce the speakers, keep the session on time, and lead the Q&A. Producers in the session will handle all technical aspects of Zoom support for the presider.

  • Will there be a warning before cutting off the virtual session?

    Yes. The technical Zoom room Producer will private chat with the Presider to inform them time is short and to wrap up Q&A. All sessions will automatically end at 5 minutes past the session end time if they haven't concluded by that time.

    Q&A can take place after each presentation or after all the presentations have been completed.

  • Is there a maximum number of questions assigned to each presenter so all presenters get the chance to answer questions?

    There is not a maximum number of questions per presenter. The presider will need to manage time and give each presenter an equal opportunity to  answer questions.

  • I am a presider for an in-person standard oral tech room and/or a hybrid oral technical room. Do I have to preside over these rooms in person?

    Yes, you must physically be in these rooms in person to preside.

Georgia Voting Law

  • Isn’t ACS concerned with the restrictive nature of Georgia’s new voting law?

    ACS believes that voting rights are fundamental to democracy and is hopeful that all states and the federal government will ensure all of its citizens are permitted the right to vote without barrier or limitation. While the new Georgia voting law is extremely concerning, ACS took into consideration the administrative order issued by Atlanta Mayor Keisha Lance Bottoms seeking to mitigate the effect of Georgia’s new election law, as well as lawsuits seeking to overturn the Georgia law. In making its decision to have an in-person presence in Atlanta, ACS also considered calls from former gubernatorial candidate Stacey Abrams asking organizations not to boycott the city and penalize its workforce.

  • Why did the Society decide to proceed with ACS Fall 2021 as a hybrid, with an in-person component in Atlanta?

    A key factor in determining whether to proceed with the hybrid meeting was presenter preferences indicated during submission of abstracts for the meeting. For the more than 7,000 abstracts submitted, roughly half of the presenters elected to present their research in-person, while the rest opted to present virtually.

    This demonstrated member preference, plus the fact that a limited in-person meeting could be done safely in Atlanta was a contributing factor to the decision. Additionally, as the number of vaccinated individuals increases and new cases diminish, Georgia’s public health emergency order expired at 12 AM on July 1 and operations in the state has returned to pre-pandemic status.

    It is clear ACS members are eager to gather in-person safely to share their science, and this will be the first opportunity to do so in over a year.

  • Isn’t there some way ACS can indicate its concern over the new voter law while holding a portion of the hybrid meeting in Atlanta?

    In connection with its in-person portion of ACS Fall 2021, ACS is engaging the local community through enhanced chemistry outreach activities. These efforts will have a special focus on students from underrepresented populations. The outreach will have two goals: to increase awareness, excitement and understanding of chemistry, and to attract greater diversity to the STEM (science, technology, engineering and math) pipeline and the chemistry enterprise.
