Visitor management is often too narrowly connected with mass/individual tourism in protected areas. Generally, visitor management can be used in any destination for mass and individual tourism also in connection with optimization of visitor flows, visitor concentration, and optimization of...

In order to analyse the behaviour of pedestrians at the very fine scale, while moving along the streets, in open spaces or inside a building, simulation modelling becomes an essential tool. In these spatial environments, simulation requires the ability to model the local dynamics of individual...

This paper deals with the interaction between population growth and capital accumulation in an ecological perspective. Some demographic behaviours are modelled taking an ecological economics approach and combining the effects of technical progress geared to prevent decline in the marginal...

Because of the open-access nature of the environment we consider an ad hoc adjustment of people's environmental footprint to the quality of the environment. The adjustment is motivated by environmental concern, but hindered by skepticism about announced changes in the state of the environment....

Most entrepreneurship theory depicts disequilibrium as the most common state for entrepreneurial activity and yet remarkably very little empirical research investigates the role of entry and exit in this type of external environment. Drawing on economics and organizational ecology we outline...
