Use of optimization models in science and policy applications is often problematic because the best available models are very inaccurate representations of the originating problems. Such is the case with electoral redistricting models, for which there exist no generally accepted measures of...

The Cournot model makes assumptions about the knowledge of the players, which can lead to counterintuitive results when extending the basic model. Closed-loop equilibria and models with consistent conjectural variations are problematic in that they reduce or eliminate economic rents while the...

With rising obesity and concern about access to healthy and nutritious food in the United States, research on food deserts has extended over the last years. For identifying the areas whose residents are most susceptible to the consequences of living in a food desert and thus most are the most...

The principal contribution of this paper lies in demonstrating that individual climate change terms may, with statistical confidence, be identified as indicators of content and found to change in frequency over time and among industries. In doing so, the study presents a method, using automated...

Large-scale electronic shopping systems need to accommodate both (a)a large number of products, many of which are close substitutes, and (b) aheterogeneous body of customers who have complex, multidimensional andperhaps rapidly changing-preferences regarding the products for salein the system....

In the securitiesindushy, the settlement and clearing of trades dependson numerous messages to...

The aim of this paper is to address the requirements for electronic shopping systems. Large-scale computerized electronic shopping systems need to accommodate both (a) a large number of products, many of which are close substitutes, and (b) a heterogeneous body of customers who have complex,...

Hypertext is one of those neat ideas in computing that periodicallyburst upon the scene, quickly demonstrating their usefulnessand gaining widespread acceptance. As interesting, useful and excitingas hypertext is, the concept has certain problems and limitations,many of which are widely...

As measured standardly by levelized cost of energy (LCOE), onshore wind and utility scale solar PV (photovoltaic) have been rapidly declining in cost and are now reported to be the cheapest ways of generating electric power. While this is indisputably a welcome development, the fact that...

This paper describes the group decision forecasting (or prediction) problem and explores a particular case of it. The case is that of what policy the Iranian government would implement for pursuing the war with Iran during the mid-1980s. This case is described in a well-known, if controversial...
