and two anonymous reviewers from Management Science who provided helpful and insightful comments on earlier versions of this paper. Abstract Engineering design often involves a very complex set of relationships among a large number of coupled problems. It is this complex coupling that leads to iteration among the various engineering tasks in a large(More)
he growing popularity of online product review forums invites the development of models and metrics that allow firms to harness these new sources of information for decision support. Our work contributes in this direction by proposing a novel family of diffusion models that capture some of the unique aspects of the entertainment industry and testing their(More)
We use Bayesian model averaging to analyze the sample evidence on return predictability in the presence of model uncertainty. The analysis reveals in-sample and out-of-sample predictability, and shows that the out-of-sample performance of the Bayesian approach is superior to that of model selection criteria. We find that term and market premia are robust(More)
Previous research has demonstrated self-reports of lower levels of four fundamental needs as a result of short periods of face-to-face ostracism, as well as short periods of Internet ostracism (Cyberball), even when the ostracizing others are unseen, unknown, and not-to-be met. In an attempt to reduce the ostracism experience to a level that would no longer(More)
Fisheries management is characterized by multiple and conflicting objectives, multiple stakeholders with divergent interests and high levels of uncertainty about the dynamics of the resources being managed. This conjunction of issues can result in high levels of contention and poor outcomes in the management process. Management strategy evaluation (MSE) can(More)
In this paper we survey with complete proofs some well–known, but hard to find, results about constructing closed embedded minimal surfaces in a closed 3-dimensional manifold via min–max arguments. This includes results of J. The basic idea of constructing minimal surfaces via min–max arguments and sweep-outs goes back to Birkhoff, who used such a method to(More)
During June and August 1992, we tested a new technology designed to exclude cattle from specific areas such as riparian zones. Technology consisted of an eartag worn by the animal that provides an audio warning and electrical stimulus to the ear as the animal approaches the zone of influence of a transmitter. The transmitter emits a signal that narrowly(More)
