Sailboarding at the Summer Olympics Sailboarding at the Summer Olympics Sailboarding or Windsurfing has been one of the Olympic sailing events at the Summer Olympics since 1984 for men and 1992 for women. All sailors use the same One Design boards, daggerboards, fins and sails. The equipment is chosen to allow racing in a wide range of sailing conditions, as during the Olympic Games events must take place as scheduled whether or not there is enough wind for planing. Multiple medal winners include Alessandra Sensini and Barbara Kendall with three medals; and Bruce Kendall (brother of Barbara Kendall) and Dorian van Rijsselberghe with two medals.
Activity theory and culturally mediated human activity, or "activity system". This system includes the object (or objective), subject, mediating artifacts (signs and tools), rules, community and division of labor. The motive for the activity in AT is created through the tensions and contradictions within the elements of the system. According to ethnographer Bonnie Nardi, a leading theorist in AT, activity theory "focuses on practice, which obviates the need to distinguish 'applied' from 'pure' science—understanding everyday practice in the real world is the very objective of scientific practice. ... The object of activity theory is to understand the unity of consciousness and activity."
