• 2023 Sacks Prize. The ASL invites nominations for the 2023 Sacks Prize for the most outstanding doctoral dissertation in mathematical logic. Nominations must be received by September 30, 2023. The Sacks Prize was established to honor the late Professor Gerald Sacks of MIT and Harvard for his unique contribution to mathematical logic, particularly as adviser to a large number of excellent Ph.D. students. The Prize was first awarded in 1994 and became an ASL Prize in 1999. The Fund on which the Prize is based is now administered by the ASL and the selection of the recipient is made by the ASL Committee on Prizes and Awards. The Sacks Prize will consist of a cash award plus 5 years free membership in the ASL. For general information about the Prize, visit http://aslonline.org/other-information/prizes-and-awards/. Anyone who wishes to make a nomination for the 2023 Sacks Prize should consult the webpage http://aslonline.org/other-information/prizes-and-awards/sacks-prize-recipients/sacks-prize-nominations/ for the precise details of the application process. A brief summary of the procedure is provided here.

Students who defend their dissertations (equivalent to the American doctoral dissertation) between October 1, 2022, and September 30, 2023, are eligible for the Prize this year. This is an international prize, with no restriction on the nationality of the candidate or the university where the doctorate is granted. Nominations should be made by the thesis advisor, and consist of: name of student, title and 1–2 page description of dissertation, date and location of the thesis defense, letter of recommendation from the advisor, an electronic copy of the thesis in pdf form, or the address of a website from which an electronic copy in pdf form can be downloaded, and an independent second letter of recommendation. Nominations and questions about the Prize should be sent to the Committee Chair, Jouko Väänänen; pdf files sent as attachments by email to [email protected] are preferred. The form of such letters and other pertinent details can be found at the website above and need to be read prior to submitting a nomination.

Those wishing to contribute to the Sacks Prize Fund may send contributions to the Business Office: ASL, Department of Mathematics, University of Connecticut, 341 Mansfield Road, U-1009, Storrs, CT 06269-1009, USA. All such contributions are tax-deductible within the USA.

• The 2023 ASL Election. At the end of this year the ASL will elect two at-large members of the ASL Executive Committee and two at-large members of the ASL Council.

• Membership Is Now Available to Logicians in China. The ASL is excited to announce that we can once again accept members from the People’s Republic of China. Under PRC regulations we remain prohibited from mailing journals to members in China. However, we now can offer online access to the ASL journals through Cambridge University Press for members in China. Logicians employed in China who are interested in joining the ASL as new members are encouraged to apply to the ASL Committee on Membership for a free initial 2-year outreach membership by emailing their mailing address and professional affiliation to [email protected]. After two years, outreach members should contact Shannon Miller at [email protected] to pay for continued outreach membership at USD 18 per year. Details are available at https://aslonline.org/membership/individual-membership/. Questions about this arrangement can be directed to Shannon Miller, Russell Miller, or Reed Solomon.

Logicians in China, not being on the current membership list, do not receive the Bulletin of Symbolic Logic and may not see these Notices. We therefore encourage all ASL members to spread the news of this welcome change, especially to colleagues based in China.

• Emeritus and Retired ASL Individual Membership. The ASL offers retired individual members two membership options. Emeritus membership includes all the privileges of regular individual membership and is available to retired individuals who have been members of the ASL for 15 years. The dues for Emeritus membership for 2023 are US$54. The privileges attached to Retired membership include the ASL Newsletter and the right to vote in ASL elections, but do not include subscriptions to the ASL journals. Retired membership is offered to retired individuals who have been members of the Association for 20 years and is free. For more information about both options, visit http://aslonline.org/membership/.

• Free Individual ASL Membership Program for Individuals in Developing Economies.

Inquiries should be sent to the committee chairs: Andrew Arana for Europe ([email protected]) and Keita Yokoyama and Noam Greenberg for East Asia and Oceania respectively ([email protected] and [email protected]).

• Open-Access Options for ASL Journals. Authors of research articles in logic, who may wish to consider submitting those articles to the Bulletin of Symbolic Logic, the Journal of Symbolic Logic, or the Review of Symbolic Logic, should be aware that these journals now offer the option of open-access publication. All three journals are now hybrid. They still accept article submissions exactly as before, and they will still publish accepted articles just as before if the author does not opt for open access. However, for authors with mandates to publish open-access articles (or who simply prefer to do so), this option is also available. Details appear at https://www.cambridge.org/core/services/open-access-policies.

• Book and Journal Discounts for ASL Members. Several publishers offer discounts on books and journals to ASL members. For a detailed description of these discounts, see http://aslonline.org/membership/member-services-and-resources/ or write to the ASL Business Office.
