We show that countable metric spaces always have quantum isometry groups, thus extending the class of known to possess such universal quantum-group actions. Motivated by this existence problem we define and study notion loose embeddability a space (X,dX) into another, (Y,dY): an injective continuous map preserves both equalities inequalities distances. 0-dimensional compact are “generically” lo...

Organizational theories frequently rely on notions of sharing and dependence among organizational participants, but researchers usually focus on characteristics of the actors themselves instead of the relational patterns among the actors. Loose coupling is one conceptual tool that emphasizes relational patterns. Loose coupling, however, is an abstract metaphor that is simultaneously fertile and...

posed a visualization problem she and I have been interested in for several years. The problem is that of visually representing a 2D field of data that has multiple data values at each point. For example, 2D fluid flow has a vector value at each location and derived values are often available at each location. Interrante suggests using natural textures to attack this problem, because the textur...
