The cost associated with making decisions based on poor-quality data is quite high. Consequently, the management of data quality and the quality of associated data management processes has become critical for organizations. An important first step in managing data quality is the ability to...

A public decision maker needs to decide to allocate some subsidy towards the conditions for public transportation or for private transportation. If she wants to improve the collective welfare of the community based on the individual preferences between public and private transportation, she...

The allocation of limited resources to competing body parts during development may affect both the absolute and relative sizes of physical traits, creating potentially dramatic consequences for the evolution of morphology. While negative correlations between the sizes of body parts...

The Smith-Fretwell model for optimal offspring size assumes the existence of an inverse proportional relationship (i.e., trade-off) between the number of offspring and the amount of resources invested in an individual offspring; virtually all of the many models derived from theirs make the same...

This paper proposes a new method to measure and analyse the typology of regional economic growth and convergence The model was originally developed by biologists in their study of morphological change of organisms. The paper investigates Italian regions using data of Gross Domestic Product per...

The existence of fractal-like networks effectively endows life with an additional fourth spatial dimension. This is the origin of quarter-power scaling which is so pervasive in biology. Organisms have evolved hierarchical networks which terminate in invariant units, such as capillaries, leaves,...

Computer simulation modeling for policy development in planning has had difficulty gaining a consistent foothold. Reasons for this include bad experiences with large-scale, comprehensive models (e.g., Forrester, 1969) and the lack of theory that one can quantify (Batty, 1994). Batty (1994) has...

A prominent feature of comparative life histories in the well documented negative correlation between growth rate and life span [1,2]. Patterns of resource allocation during growth reflect life-history differences between species [1,2]. This is particularly striking in tropical forests, where...

The innovation is a main variable of the economic growth, but the origin and diffusion of innovations are functions of several variables. For this reason, the contributions of other disciplines have been used to understand in depth its behaviour and spatial-temporal dynamic. The aim of this...
