A Section is the most broadly defined program unit, representing areas of general interest, and it offers presenters the most access for unsolicited papers. Normally Sections are responsible for two sessions at the Annual Meeting. Often one session is used for invited papers or a panel discussion, while the other session is constructed from presentations submitted by members at large in response to the general call for papers. Sections may also use their two assigned sessions to address different topics within their area of study. At a minimum, one of the two sessions must be constructed from papers submitted in response to the general call for proposals. Sections normally have a six-year term and are renewable indefinitely, contingent on the demonstration of continued viability and compliance with the goals for all program units and the Society at large. Responsibility for Sections resides with each Section’s chairperson and steering committee, answerable to the Executive Committee (via the Program-Units Committee).
