This special issue of the Journal of Research Practice focuses on integration research, also known as integrated or integrative research. Integration between disciplines and between research and practice is increasingly recognised as essential to tackle complex problems more effectively. But there is little to guide researchers about how to undertake integration research. This special issue provides a number of case studies of how integration has been approached and exemplifies the challenges facing researchers seeking to embed integration in both existing and (...) new organisations and make it acceptable and respectable. Documenting these developments provides a unique illustration of how integration research is evolving as a type of practice. (shrink)
