WELCOMEWe are delighted to welcome you to the sixth OAP workshop! After Paris in , London in 2013, Roma in 2014 and Sydney in 2015 it is a pleasure to now meet in Lisbon, for a new series of exciting presentations and debates on organizations, artefacts and practices.This year's theme is again a challenging one. Institutions, institutionalizations, legitimation processes have undergone radical changes over the last decades. With the increasing use of digital technologies, the ongoing transformation of work and workplaces (including an entrepreneurial trend) and the shifting of work boundaries (private-professional spheres, producers-consumers spheres…), the modalities of emergence and transformation of institutions (their temporalization and spatialization) are changing.OAP 2016 will be focused on the theoretical perspectives and ontologies that inform the (meaning of these) new modalities of institutions and institutional dynamics, and that affect how these changes matter. OAP 2016 engages with numerous neo-institutional, post-discursive, sociomaterial, post-Marxist, processual or phenomenological views, all of which emphasize the visual, material, temporal and spatial dimensions of institutionalization, legitimation or the dynamics of institutional logics.We are very pleased with the quality of the submissions we received, and with the diversity of disciplines, intellectual traditions and research methods represented in the workshop.
