Researchers from Europe, the US, Israel, and Australia present 13 essays that examine the emergence, construction, and transformation of actors and their agency, action, and authority in institutions in various contexts. The first section considers the meanings, construction, and emergence of actors in institutions, including different types of actors, school principals, the concept of actorial identity through the construction of legal persons as actors, nonprofits as organizational actors, the role of active clients in universities, and the institutional construction of organizations as actors. The second section discusses the work of actors in episodes of institutional change and stability, with discussion of the emergence of evidence-based medicine in American health care, the emergence of the profession of scientific winemaking in the Australian wine industry, the incorporation of Islamic banking and organic agriculture within the legal system in Turkey, changes in sherpa actorhood in mountaineering, and the struggle for legitimacy of the LGBT community in Israel.
