Three paper sessions are usually gender-related and the other three are in a topic area that changes from year to year.
Sessions generally have three or four papers and two to four discussants.
The papers presented in the sessions will normally be selected from the submissions. Sometimes an organizer will solicit additional presenters to strengthen the theme of the session. At least one author must be a member of the association sponsoring the meeting, if so required. Co-authors may be of either sex and may be junior or senior. Junior men may author papers in the gender-related sessions.
