This is a position statement for the workshop on strategic directions in computing research held at MIT in June 1996.

This paper describes the outline of an object-oriented design technique denoted role modeling, emphasizing the ability to compose parts of a design. The purpose of role modeling is to achieve separation of concerns, allowing the designer to consider different aspects, or the same aspect at different levels of detail, more or less independent of other aspects of the overall design. A role model ...

This paper proposes a formal framework for the design of real-time shared data-space systems. The proposed method separates the concerns of functionality, behavior, and timing. This work exploits the idea of separation of concerns at the specification and design level, and it establishes a robust theoretical basis that allows rigid analysis and verification of (timed) designs.

Information exploration processes are usually recognized by their inherent complexity, lack of knowledge and uncertainty, concerning both the domain and the solution strategies. Even though there has been much work on the development of computational systems supporting exploration tasks, the lack of a formal understanding of the exploration process and the absence of a proper separation of conc...

The incomplete information financial economic equilibrium (IIE) literature has been growing at a growing rate since its inception in the early nineteen eighties. This paper highlights, clarifies, and examines issues and concepts essential to this equilibrium. These include: the number of state variables, irrelevance of separation theorems, unobservable productivity processes that lead to comple...

This paper is about studying how organisations can share data without losing control about one’s position, role, and importance in a cooperation. We introduce the framework of sharing by separation of concerns as a model. Based on an ethnographic study, we apply our framework in a real work context. We show how this framework offer an easy solution to share certain information across organisati...
