Since the early seventies concepts of specification have become central in the whole area of computer science. Especially algebraic specification techniques for abstract data types and software systems have gained considerable importance in recent years. They have not only played a central role in the theory of data type specification, but meanwhile have had a remarkable influence on programming language design, system architectures, arid software tools and environments. The fundamentals of algebraic specification lay a basis for teaching, research, and development in all those fields of computer science where algebraic techniques are the subject or are used with advantage on a conceptual level. Such a basis, however, we do not regard to be a synopsis of all the different approaches and achievements but rather a consistently developed theory. Such a theory should mainly emphasize elaboration of basic concepts from one point of view and, in a rigorous way, reach the state of the art in the field. We understand fundamentals in this context as: 1. Fundamentals in the sense of a carefully motivated introduction to algebraic specification, which is understandable for computer scientists and mathematicians. 2. Fundamentals in the sense of mathematical theories which are the basis for precise definitions, constructions, results, and correctness proofs. 3. Fundamentals in the sense of concepts from computer science, which are introduced on a conceptual level and formalized in mathematical terms.

The students of computer science at Herat University have even fought for their right to study, young women as well as Their yearning for education was the driving force for the establishment of their own Faculty of Computer Science. Up to eighteen hours a day they were busy in completing the mere shell of a building where they might pursue their studies and acquire an understanding of computer science. Some of them are used to walk up to three hours just to reach the university. Yet, a long-term guarantee of continued courses is still not in sight. This report therefore does not only mean to give an account of the past accomplishments in reconstruction. It also aims to call upon the international community not to ignore these students, but to support them in a sustainable manner and to preserve their present access to higher education.
