Computer Science—the theory, representation, processing, communication and use of information—is fundamentally transforming every aspect of human endeavor. The Department of Computer Science at Iowa State University advances computational and information sciences through; 1. educational and research programs within and beyond the university; 2. active engagement to help define national and international research, and 3. educational agendas, and sustained commitment to graduating leaders for academia, industry and government.
History
The Computer Science Department was officially established in 1969, with Robert Stewart serving as the founding Department Chair. Faculty were composed of joint appointments with Mathematics, Statistics, and Electrical Engineering. In 1969, the building which now houses the Computer Science department, then simply called the Computer Science building, was completed. Later it was named Atanasoff Hall. Throughout the 1980s to present, the department expanded and developed its teaching and research agendas to cover many areas of computing.

Abstract
This paper describes MiniMAO1, a core aspect-oriented calculus. Unlike previous aspect-oriented calculi, it allows around advice to change the target object of an advised operation before proceeding. MiniMAO1 accurately models the ways AspectJ allows changing the target object, e.g., at call join points. Practical uses for changing the target object using advice include proxies and other wrapper objects.
In addition to accurate modeling of bindings for around advice, MiniMAO1 has several other features that make it suitable for the study of aspect-oriented mechanisms, such as those found in AspectJ. Like AspectJ, the calculus consists of an imperative, object-oriented base language plus aspect-oriented extensions. MiniMAO1 has a sound static type system, facilitated by a slightly different form of proceed than in AspectJ.
This paper gives an operational semantics, type system, and proof of soundness for MiniMAO1.
