This article contributes to our understanding of how boundary work is practiced in healthcare settings. Previous studies have shown how boundaries are constantly changing, multiple, and co-existing, and can also be relatively stable cognitive and social distinctions between individuals and groups. In highly specialized, knowledge-intensive organizations such as healthcare organizations, organizational, professional, and disciplinary boundaries mark the formal structure and division of work. Collaboration and coordination across these boundaries are essential to minimizing gaps in patient care, but also may be challenging to achieve in practice. By drawing on data from an ethnographic study of two hospital wards, this article investigates practices of cross-disciplinary and professional collaboration and adds to our knowledge of how this kind of boundary work is produced in context. Moreover, it adds to existing boundary literature by exploring the fast-paced, situational, micro-interactions in which boundaries are drawn, maintained, and dissolved. These mundane, brief exchanges are essential to the practice of collaboration through boundary work. I consider the implications of these findings for boundary theory and boundaries in healthcare and other related settings.

"Boundary Images investigates the political, material, and visual work that images do to cross and blur the boundaries between the technological and biological and between humans, machines, and nature. Exploring the limits of the visual and beyond what can be seen, Boundary Images posits these boundaries as starting points for the production of new and radically different ways of knowing about the world"--

Freedom of speech is a fundamental human right and a core value in liberal democracies. It is also, however, one of our time's most contested issues, constantly claimed to be either too wide-ranging, at the peril of vulnerable minority groups, or too limited, restricting dissent and democratic deliberation. Employing a sociological lens on the dynamics of the public sphere, this book investigates how the boundaries of free speech are contested and negotiated through social processes which silence certain groups and opinions while amplifying others. The book focuses on key topics in current free speech debates – immigration, religion and culture. Drawing on population-representative survey data, media analysis and in-depth interviews, the authors paint a broad picture of how boundaries of free speech are defined and maintained, experienced and challenged, in the rapidly changing Norwegian public sphere.
