MIME is a research project on multilingualism in Europe, funded by the European Commission’s Seventh Framework Programme. Using an innovative interdisciplinary approach, MIME will generate an organised body of policy-relevant propositions, identifying the language policies and strategies that best combine “mobility” and “inclusion.” The diverse concepts and methods are combined in an analytical framework designed to ensure their practice-oriented integration. MIME identifies, assesses and recommends measures for the management of trade-offs between the potentially conflicting goals of mobility and inclusion in a multilingual Europe. Rather than taking existing trade-offs as a given, we think that they can be modified, both in symbolic and in material/financial terms, and we argue that this objective can best be achieved through carefully designed public policies and the intelligent use of dynamics in civil society.
