A long history of dynamical analyses of food-web networks has led to important insights into the effects of complexity, omnivory and interaction strength on food-web stability. Some recent insights are based on nonlinear bioenergetic consumer-resource models that display chaotic behavior in...

Secondary structures of polynucleotides can be view as a certain class of planar vertex-labeled graphs. We construct recursion formulae enumerating various sub-classes of these graphs as well as certain structural elements (sub-graphs). First order asymptotics are derived and their dependence on...

In this paper we describe the application of massively parallel processing (MPP) to the problems involve sequences of numbers (for example, the daily closing values of the stock market, EEG patterns of brainwave activity, or, as discussed in this paper, the temporal values from set of equations...

This paper presents an agent-based, object-oriented ecological model of forest dynamics designed to examine the role of disturbance on diversity. Arborscapes is based on Swarm, an agent-based software platform that offers advantages for ecological modeling, including a suite of standardized...

The paper generalizes the Kiyotaki-Wright trade model by treating the trading period as a finite game, so Nash's theorem can be used to prove the existence of equilibrium, and by treating the economy as a Markov process, so an ergodic theorem can be used to show the existence of equilibria with...

Many of the applications of game theory have been to economics where the individuals under study are assumed to be maximizing profits or Òutility'' or some other conventional economic goal of Òstatus.'' Loosely stated we think of status as one's position in a society compared with others,...

There is increasing evidence that collective behavior, such as social choice, price dynamics, and strategic behavior, is related to nonlinear dynamics and thus has the potential for instability and complex behavior. This paper presents experimental results where subjects are placed in a...

Within the resource-based view of the firm, a dynamic story has emerged in which the knowledge accumulated over the history of a firm and embedded in organizational routines and structures influences the firmÕs ability to recognize the value of new resources and capabilities. This paper...

The spatial model of voting is a benchmark in theories purporting to explain political behavior. Yet, evidence against the accuracy of both the assumptions and predictions of the spatial model is accumulating in the scholarly literature. One long-held result of spatial theory is that incumbents...

The Dvorak keyboard has been claimed to be greatly superior to the standard typwriter keyboard. However, none of the earlier research on the relative merits of the two keyboards provided unconfounded measures, ones permitting attributrion of the results solely to the differences between the...
