Increasingly, everyday living and practices depend on how mobility (and immobility) is articulated through the ever-present influence of a range of physical and virtual infrastructures. This book focuses in particular on the 'political' dimension of mobility and immobility, which plays a key role in establishing patterns of proximity in real and virtual co-presence. Proximity is seen as the result of choices, negotiations and practices carried out in different settings. Drawing from different literature streams (Sociology, Organization Studies and Science and Technology Studies), this book analyses patterns of mobility in relation to new possibilities of organizing space, time, and proximity to others. Different phenomena - from memorial sites to migration, from urban mobility to mobile work - are analysed, illustrating different types of proximity through mobility and immobility. In doing so, this book offers a cross-cultural and innovative theoretical framing of issues linked to mobility, through the link with immobility and proximity.
