The aim of the sparse analytic hierarchy process (SAHP) problem is to rank a set of alternatives based on their utility/importance; this task is accomplished by asking human decision-makers to compare selected pairs of alternatives and to specify relative preference information, in the form of ratios of utilities. However, such an information is often affected by subjective biases or inconsistencies. Moreover, there is no general consent on the best approach to accomplish this task, and in the literature several techniques have been proposed.

Background: Neuroimaging and neuropsychological studies have suggested that common features characterize both Gambling Disorder (GD) and Alcohol Use Disorder (AUD), but these conditions have rarely been compared. Methods: We provide evidence for the similarities and differences between GD and AUD in neural correlates of executive functions by performing an activation likelihood estimation meta-analysis of 34 functional magnetic resonance imaging studies involving executive function processes in individuals diagnosed with GD and AUD and healthy controls (HC).

Perceptual discriminations can be strongly biased by the expected reward for a correct decision but the neural mechanisms underlying this influence are still partially unclear. Using functional magnetic resonance imaging (fMRI) during a task requiring to arbitrarily associate a visual stimulus with a specific action, we have recently shown that perceptual decisions are encoded within the same sensorimotor regions responsible for planning and executing specific motor actions. Here we examined whether these regions additionally encode the amount of expected reward for a perceptual decision.

The voluntary control of movement is often tested by using the countermanding, or stop-signal task that sporadically requires the suppression of a movement in response to an incoming stop-signal. Neurophysiological recordings in monkeys engaged in the countermanding task have shown that dorsal premotor cortex (PMd) is implicated in movement control. An open question is whether and how the perceptual demands inherent the stop-signal affects inhibitory performance and their underlying neuronal correlates.

Humans have generally been considered risk averse for gains. Yet, growing evidence shows that risk preferences may
change across reward currencies and depend on the type of tasks used to measure them. Here, we examined how
context affects human risk preferences to shed light on the psychological mechanisms underlying human decisionmaking
under risk. Participants were presented with a descriptive risky choice task involving repeated choices
between real options and they were provided with trial-by-trial feedback. We manipulated the type of reward and, for

Real estate and land management are characterised by a complex, elaborate combination of technical, regulatory and governmental factors. In Europe, Public Administrators must address the complex decision-making problems that need to be resolved, while also acting in consideration of the expectations of the different stakeholders involved in settlement transformation.
