Discounting in pigeons when the choice is between two delayed rewards: implications for species comparisons

Frontiers in Neuroscience, 2011
Studies of delay discounting typically have involved choices between smaller, immediate outcomes and larger, delayed outcomes. In a study of delay discounting in humans, Green, Myerson, and Macaux (2005) added a period of time prior to both outcomes ...

Relatively hyperbolic groups are C*-simple [PDF]

, 2006
We characterize relatively hyperbolic groups whose reduced C*-algebra is simple as those, which have no non-trivial finite normal ...

Does temporal discounting explain unhealthy behavior? A systematic review and reinforcement learning perspective

Frontiers in Behavioral Neuroscience, 2014
The tendency to make unhealthy choices is hypothesized to be related to an individual's temporal discount rate, the theoretical rate at which they devalue delayed rewards.

Asymptotic orbital shadowing property for diffeomorphisms

Open Mathematics, 2019
Let M be a closed smooth Riemannian manifold and let f : M → M be a diffeomorphism. We show that if f has the C1 robustly asymptotic orbital shadowing property then it is an Anosov diffeomorphism. Moreover, for a C1 generic diffeomorphism f, if f has the

Measure-Expansive Homoclinic Classes for C¹ Generic Flows

Mathematics, 2020
In this paper, we prove that for a generically C1 vector field X of a compact smooth manifold M, if a homoclinic class H(γ,X) which contains a hyperbolic closed orbit γ is measure expansive for X then H(γ,X) is hyperbolic.

Quantitative Cross-Cultural Similarities and Differences in Social Discounting for Gains and Losses

Frontiers in Public Health, 2019
Social discounting is when resource allocation decreases as social distance increases. Studies fitting different quantitative models to social discounting data have shown that a q-exponential function based on Tsallis' statistics best fits loss data ...

Obesity and Hyperbolic Discounting: An Experimental Analysis

Journal of Agricultural and Resource Economics, 2012
Models of rational addiction suggest that obesity is consistent with time-consistent preferences. Behavioral economists maintain that addictions such as alcoholism, smoking and over-eating represent examples of present-bias in decision making that is ...
