Eligibility requirements: Any independent graduate student research (including, but not limited to, the doctoral dissertation) is eligible. The work presented may be part of a larger collaborative effort, but the student should have the principal responsibility for the conceptualization and design of the research, the collection and analysis of the data, and the interpretation of the results. The entrant cannot have completed defense of the doctoral dissertation before the preceding ABS annual meeting. An individual can enter the session only once per lifetime. Only single-authored papers are eligible for the session.
