The dynamics of both the General Factor of Personality and the personality biological indicators, as a consequence of a stimulus, can be described with a short-term dynamic model (the response model). The invariance of the ...

[EN] There are few studies developed about the general factor of personality (GFP) dynamics. This paper uses a dynamical mathematical model, the response model, to predict the short-term effects of a dose of alcohol on GFP ...

This paper presents a new well-being index which allows environmental quality to be measured through CO2 emissions, renewable energies and nuclear power. Its formula derives from a geometric mean used to calculate which ...

A model for a general human population dynamics is presented to approach the demographic stability problem. The main model variables are demographic variables per sexes (births, deaths, emigration, immigration and population) ...
