Somatic markers have been evidenced as determinant factors in human behavior. In particular, the concepts of somatic reward and punishment related to decision-making process; both represent bodily states with positive or negative sensations, respectively. this research work, we designed a mechanism generate artificial punishments an autonomous system. An system is understood capable performing behavior decision making. We incorporated within model oriented support making on stock markets....

Abstract This work analyzes the implementation of an artificial mechanism inspired by a biological somatic marker that ables passenger agent to both, react changes in service, as well keep said reactions memory for future decisions. An mental model was designed, and implemented autonomous decision-making system, where choice transport operator evaluation received service were fully delegated system. The experience is not only based on rational aspects (such cost trip) but also subjective...

Entrepreneurship is widely recognized as a vital driver of economic growth, yet its relationship through different stages with broader, non-purely monetary dimensions still needs to be explored. This research seeks fill this gap by investigating the association between human development and entrepreneurship, recognizing crucial role environmental conditions in shaping entrepreneurial activity. Our cross-country Bayesian analysis shows strong evidence that nation's level associated activity...
