It is shown how to derive, following the principles of the SMoLCS methodology, a family of calculi, suitable for the specification of concurrent systems and languages. A calculus consists basically of a language for expressing behaviours and their parallel composition together with the rewriting rules defining their semantics; formally it is a calculus associated to an algebraic parameterized specification: for every choice of the parameters we fix one calculus in the family. The distinguishing feature of our calculi is that the combinators for behaviours include functional abstraction and application, so that behaviours can be passed as arguments and obtained as results of functions; in general behaviours can be seen just as a data type and in this sense our calculi can be higher order calculi with behaviours as first class objects.

Abstract
It is shown how to derive, following the principles of the SMoLCS methodology, a family of calculi, suitable for the specification of concurrent systems and languages. A calculus consists basically of a language for expressing behaviours and their parallel composition together with the rewriting rules defining their semantics; formally it is a calculus associated to an algebraic parameterized specification: for every choice of the parameters we fix one calculus in the family. The distinguishing feature of our calculi is that the combinators for behaviours include functional abstraction and application, so that behaviours can be passed as arguments and obtained as results of functions; in general behaviours can be seen just as a data type and in this sense our calculi can be higher order calculi with behaviours as first class objects.
