In this article, the authors re-visit, with Val Larsen, the use of Peircean icons and symbols in print advertising and thereby find (some) formal conditions concerning its images. Even though they are inspired by Val Larsen's research program the authors are also critical of it. Hence, they set...

Recent research on contingent claims valuation has assumed increasingly general models of the behavior of cash securities. Relatively few attempts have been made to implement and evaluate such models empirically, however. In this paper we apply a multi-factor, continuous time pricing model to...

West European security Implications of five alternative defense scenarios arc assessed for the period 1985 to 2000. The main characteristics of each of the five scenarios are (1) current nuclear and conventional posture trends, (2) a submarine based, West European strategic nuclear force, no...

After a brief discussion of the motivations and criteria for making energy plans based on renewable sources, a number of renewable energy plans is reviewed. The way in which such plans are constructed is investigated and a critical appraisal of each plan is attempted. Finally, some remarks are...

Starting from explicit value preferences, an energy system compatible with an alternative American future is outlined, based on efficient use of energy and renewable energy sources. It is demonstrated that the U.S. may become self-sufficient before 2000 and use only renewable energy by 2030. A...

Global scenarios of energy provision with zero net emissions of greenhouse gases are considered. The scenarios assume the same demand for energy services and a high degree of emphasis on energy efficiency, with supply options clean fossil fuels, safe nuclear power, centralised or decentralised...

In contrast to conventional energy modeling made on a national basis, we consider energy use and supply per unit of land area. This is particularly suited for dealing with dispersed energy resources such as renewable energy, and by making the match of demand with supply on this basis in a...
