Conference Presentation Policies Each individual may submit only one abstract, whether of sole or multiple authorship and whether an individual paper, a poster, or as part of a colloquium.  Each person may appear in the program only once as a presenter of an individual paper, poster or colloquium paper; in addition, the same individual may appear in the program once as a discussant and once as a colloquium organizer. All proposals (for individual papers, colloquia papers, and poster sessions) are assumed to represent original and unpublished work that is not yet available to AAAL membership (with the exception of material from publications in press). Proposal submissions from individuals who will not attend the conference are discouraged. Substitute readers are disadvantaged in discussing papers with the audience. Presenters who know in advance that they cannot attend the conference are requested to withdraw their proposals, thus opening a conference slot for someone who can attend. If unforeseen circumstances, at the last minute, dictate that a presenter cannot attend the conference, a substitute reader will be permitted.
