Ai-Wen Hwang, PhD, PT is Associate Professor at Graduate Institute of Early Intervention, Chang Gung University, Tao-Yuan, Taiwan. She has served at the child developmental center and child assessment center in Taiwan over 15 years. She is also one of the members of Task Force of Disability Eligibility System in Taiwan.

Mats Granlund is full professor of psychology and disability science at Jönköping University and guest professor of Special Education at Oslo University. His main research area in the last 15 years is every day functioning, operationalized as participation, of children and youth in need of special support. In this area he has a long-standing collaboration with researchers from Taiwan, Australia, USA, Canada and South Africa. Mats has published extensively in this area. Current two main strands of research are the evaluation and further development of the ICF-CY classification and investigating two dimensions of participation being there, and engagement while being there. Activity competence with the components capacity, capability and performance is studied as a factor strongly influencing participation.
