The actions collectively selecting one or more members from a hierarchy of members. The hierarchy of members is associated with a particular dimension of an organization of data. The method further includes recording the sequence of actions in a member selection script. In addition, the method includes executing the member selection script to select one or more members after the hierarchy of members has been modified.

Abstract: A water resistant reusable sleeve for medical dressings, inclusive of medical bandages and casts having a generally tubular member and defining a sleeve-like cavity tapered for receiving an extremity of an individual with a plaster cast, a splint, or a surgical dressing. The reusable sleeve is designed so as to be ergonomic or tapered to more closely accommodate the extremities of a user, providing a better fit, a more effective watertight seal with the skin, and also providing an important aesthetic advantage. Elastic bands of a size and elasticity so as to apply sufficient elastic force for sealing the sleeve to the appendage without creating a tourniquet effect are disposed on at least one end of the reusable sleeve. Furthermore, the water resistant reusable sleeve is preferably made of a composite material or a matrix material to prevent tearing of the material substrate during use and may incorporate a design.
