Work on aspect-oriented programming [3] and subject-oriented programming [2,4] has identified difficulties associated with code tangling in software development. Each has provided solutions for separating code that affects many units of functionality in the system (i.e. cross-cutting code), with corresponding composition techniques to integrate cross-cutting and component code. Benefits common ...

Feature-Oriented Software Development (FOSD) provides a multitude of formalisms, methods, languages, and tools for building variable, customizable, and extensible software. Along different lines of research, different notions of a feature have been developed. Although these notions have similar goals, no common basis for evaluation, comparison, and integration exists. We present a feature algeb...

Despite the abundance of research on teachers’ repair practices in language classroom interaction, there are not enough conversation analytic studies on repair organization with the focus on the details of interaction in the context of EFL. Drawing on sociocultural and situated learning theories, this study explores the contingent nature of English language teachers’ org...

This study aims at empirically furthering awareness of the organization of interaction in EFL classes. Informed by the methodological framework of conversation analysis, it draws upon a corpus of 52 three-hour naturally-occurring classroom interaction to identify classroom interactional contexts based on the structuring of the pedagogic goals in turn-taking sequences. Conversation analytic proc...

The expression of new aspect-oriented structures of the 23 GoF design patterns in term of a pivot meta-model that we propose for aspect-oriented modelling; proves strong similarities between most of the models that we obtained for these patterns. This work led us therefore to propose a new taxonomy of patterns and consequently to identify a new set of aspect-oriented design patterns. We propose...

We describe the coordination model of the Neem Platform, a research test bed for Project Neem, concerned with the development of socially and culturally aware collaborative systems in a wide range of

Based on a general model of feature composition, we present a composition language that enables programmers by means of quantification and weaving to formulate extensions to programs written in different languages. We explore the design space of composition languages that rely on quantification and weaving and discuss our choices. We outline a tool that extends an existing infrastructure for fe...
