In this article, I use Albert Hirschman's consumer-based 'exit' and 'voice' concepts in order to set out the political ecology of voice (PEV), an innovative theoretical framework that aims to examine the causes of environmental pollution from a new angle. I begin by providing a brief overview of political ecology, and why it provides such a useful framework from which to position Hirschman's id...

We examine how a firm’s changing environment and the information constraints of its managers interact as determinants of the size of the firm’s administration. Following the recent decentralized information processing literature, we assume that it takes individual managers time to process information. A consequence is that it takes time for a firm to aggregate information, even when this task i...

the authors have developed methods to characterize and quantify uncertainty in acoustic environmental predictions. We have developed methods for reflecting this uncertainty in tactical systems such as senor performance prediction, search plan recommendation, and track and detect systems that rely on environmental inputs. Uncertainty in performance prediction can result from model error and unce...
