The main purpose of this paper is to describe a simple model for the understanding of empirical and analytical potential achievements of the NIS approach , particularly with regards at the sources that explain different growth performances across countries. First, the paper provide a summary...

This paper aims at providing a survey (by no means exhaustive) of evolutionary theorizing, where by this we mean all the contributions which possess the methodological building blocks of an evolutionary theory, which this approach identifies as the consideration of dynamics, the presence of...

In this essay, the author assesses the operation of the Non-Compliance Procedure of the Montreal Protocol on Substances That Deplete the Ozone Layer. Although in operation for only six years, the Procedure and its standing Implementation Committee have already made significant contributions to...

The problem of water quality management under uncertain emission levels, reaction rates and pollutant transport is considered. Various performance measures: reliability, resiliency and vulnerability are taken into account. A general methodology for finding a cost-effective water quality...

All population projections are based in one form or another on expert judgement about likely future trends, structural continuity, etc. Although experts are clearly superior to lay people in their field of expertise, when it comes to forecasting they may make serious errors and can be as...

In 1997, the dynamic Family Microsimulation Model FAMSIM, a microsimulation model for projections and the evaluation of family policies - was developed at the Austrian Institute for Family Studies, in collaboration with IIASA. The purpose of the FAMSIM project was to demonstrate the feasibility...

In this paper, we consider the problem of incorporating additional preference information into Value Efficiency Analysis by using the "price" information of inputs and outputs. This is done to improve the accuracy of the estimation of the Value Efficiency Scores. Value Efficiency developed by...

The temporal dynamics of many populations involve intermittent rarity, that is, the alternation, over variable periods of time, of phases of extremely low abundance, and short outbreaks. In this paper we show that intermittent rarity can arise in simple community models as a result of...
