Since 1989 the Open University MBA has offered practicing managers a route to improved professional practice and career development. Experience with a new consultancy module suggested that a substantial proportion of students were not benefitting as intended. Students were learning theory instrumentally rather than using it to prompt rethinking of their assumptions and practice. Action research...

Collaboration between the private and public sectors has produced mixed results. Some initiatives seem better suited to this model. For example, partnerships in national defense and space exploration have produced benefits to both sectors, although not without some controversy.

The role graph model, its operator semantics based on graph theory and algorithms for role administration are proposed. The role graph model, in our view, presents a very generalized form of role organization for access rights...
