Inter-organizational B2B systems are most likely tending to change their business requirements over time e.g. establishing new partnerships or change existing ones. The problem is that business analysts design the business processes from scratch, disregarding the economic drivers of the business network. We propose to use business modeling techniques such as REA (Resource-Event-Agents) to ensur...

This study assesses the potential of an integrated methodology for predicting local trends in invasive exotic plant species (invasive richness) using indirect, regional information on human disturbance. The distribution of invasive plants was assessed in North Portugal using herbarium collections and local environmental, geophysical and socio-economic characteristics. Invasive richness response...

The paper considers random economic systems generating nonlinear time series on the positive half-ray R+. Using Lyapunov techniques, new conditions for existence, uniqueness and stability of stationary equilibria are obtained. The conditions generalize earlier results from the mathematical literature, and extend to models outside the scope of existing economic methodology. Applications to growt...

In this paper is described a model of residential mobility, built to simulate individual households, their perception of and reaction to varying conditions across different scales of interaction, and their movements to occupy housing in a physical, social, and economic environment. The methodology underpinning the model is based on an automata core, which leverages the advantages it offers in t...

This paper presents Gary Becker's approach to conducting creative, empirically fruitful economic research. It describes the traits and methodology that made him such a productive and influential scholar.

Many communities are interested in developing and maintaining recreational trails to benefit trail users and as tourist attractions to stimulate economic growth. In this paper, a study is described which estimates the net economic value to trail users and the local economic impacts of the Virginia Creeper Rail Trail in south-western Virginia, USA. The monetary valuation results suggest that the...
