Subject Composition by Roles
نویسنده
چکیده
Subjects model diierent perspectives on a problem domain by collections of related class hierarchies. Subjects can be seen as the result of separate and possibly independent development processes for partial models. The subjects can be eeciently composed by a technique that builds on the notion of roles. The composition allows already combined subjects to be further combined or to be dissolved and combined anew.

An Optimistic Approach for the Specification of more Flexible Roles Behavioural Compatibility Relations in MAS
In this paper we focus on a new approach to the definition of more flexible roles compatibility in MAS. We provide a formal framework for modeling roles together with their composition, taking into account the property preservation such as the completion and the proper termination of roles. We show the existing link between roles compatibility and substitutability, namely the preservation of th...

متن کاملLegal briefing: Healthcare ethics committees.
This issue's "Legal Briefing" column covers recent legal developments involving institutional healthcare ethics committees. This topic has been the subject of recent articles in JCE. Healthcare ethics committees have also recently been the subject of significant public policy attention. Disturbingly, Bobby Schindler and others have described ethics committees as "death panels." But most of the ...
