Watershed nutrient management is essential in minimizing the eutrophication rate of reservoirs. A shortcoming in nutrient management of watershed-reservoir systems has been the lack of successful linking of watershed and water body models to evaluate impact of watershed management options on reservoir water quality. The objectives of this research were to 1) calibrate and validate a Soil and Wa...

The crucial point of the mind-body-problem appears to be that mental phenomena (events, properties, states) seem to have features which at first sight make it impossible to integrate these phenomena into a naturalistic world view, i.e. to identify them with, or to reduce them to, physical phenomena.1 In the contemporary discussion, there are mainly two critical features which are important in t...

Introduction This brief note presents an economic perspective on “me-too” drugs (sometimes also called “follow-on” drugs). Me-too drugs are products which largely duplicate the action of existing drugs. Several recent books (such as Angell (2004), Avorn (2004) and Goozner (2004)) have heaped criticism on the drug industry for the increasing extent to which investment appears to be focused on de...

Understanding the effects of climate change including precipitation patterns has important implications for evaluating the biogeochemical responses of watersheds. We focused on four storms in late summer and early fall that occurred after an exceptionally dry period in 2002.We analyzed not only the influence of these storms on episodic chemistry and the role of different water sources in affect...

This article examines arguments concerning enhancement of human persons recently presented by Michael Sandel (2004). In the first section, I briefly describe some of his arguments. In section two, I consider whether, as Sandel claims, the desire for mastery motivates enhancement and whether such a desire could be grounds for its impermissibility. Section three considers how Sandel draws the dis...

Most literature on the hold–up problem assumes that ex post bargaining outcomes are insensitive to prior investment costs. However, many bargaining procedures admit multiple equilibria and hence allow investment costs to affect bargaining outcomes. On the other hand, multiplicity of equilibria leaves scope for coordination failure. We report on three experiments in which unilateral investment i...

We argue that Quantum Gravitation forces us to sum over metrics of all signatures. Since the beginning of General Theory of Relativity the metric has played the dynamical role of the gravitational potential. This has led to an enormously successful classical theory of gravitation. All subsequent efforts at a quantum theory of gravitation have therefore been built around the idea that the gravit...
