The NAc, the amygdala, and the medial prefrontal cortex are implicated as central sites of action for the suppressive effects of the DA-1 receptor (D1R) and DA-2 receptor (D2R) antagonists (SCH23390 and raclopride, respectively), on sugar intake and on the expression of flavour preferences conditioned by the sweet taste of sugars.
In the previous section we established the revealed preference conditions for exact linear aggregation.
In this section, we start by briefly reviewing the revealed preference conditions for rational consumption behaviour of individual consumers in terms of the well-known Afriat inequalities.
We adapt this algorithm to our setting (i.e. replace the revealed preference conditions for utility maximization by the ones of exact linear aggregation) and as such we can calculate bounds on the minimal number of aggregable groups.
The methodology is tested under non-stationary preference conditions using simulated and real human decision makers, and it is also compared with a non-interactive genetic algorithm and a previous version of the interactive genetic algorithm.
A seasoned crowd: diverse in age, appearance, sexual preference, condition of mind.
It was deemed not logically possible to have genuine preferences for identical stimuli, therefore these responses were assumed to be responses elicited in the 'no preference' condition.
These schemes are not efficient enough, as they do not take into consideration the traffic characteristics, user preferences, network conditions and other important system metrics.
This study addresses the coexistence of these species within severely limited barren grounds by assessing differences in population structure, feeding preferences and conditions.
The SG method has been widely used to measure individual preferences in conditions of uncertainty (Gafni, 1994).
