Abstract
The door is the boundary between the foreign and domestic worlds in the case of an ordinary dwelling, between the profane and sacred worlds in the case of a temple. Therefore to cross the threshold is to unite oneself with a new world (van Gennep 1960: 20). The theme of the 2012 American Anthropological Association (AAA) meeting in San Francisco was "Borders and Crossings." A session on "Ethics in Business Anthropology" seemed appropriate given the number of anthropologists increasingly crossing borders from academia to business and moving into business as a full-time career or operating between academia and business. The articles in this issue are based upon papers presented in a session entitled "Ethics in Business Anthropology" held at the meeting.
