Connecting choice functions and sets of desirable gambles [PDF]
, 2014 We study Seidenfeld, Schervish, and Kadane’s notion of choice functions, and want to make them accessible to people who are familiar with sets of desirable gambles. We relate both theories explicitly using their derived strict partial orderings.

Exchangeability for sets of desirable gambles [PDF]
, 2009 Sets of desirable gambles constitute a quite general type of uncertainty model with an interesting geometrical interpretation. We study exchangeability assessments for such models, and prove a counterpart of de Finetti's finite representation theorem. We

Exchangeability and sets of desirable gambles
International Journal of Approximate Reasoning, 2012 Sets of desirable gambles constitute a quite general type of uncertainty model with an interesting geometrical interpretation. We give a general discussion of such models and their rationality criteria. We study exchangeability assessments for them, and prove counterparts of de Finetti's finite and infinite representation theorems.

Stigmatisation of people experiencing gambling-related harms: a vignette study of the predictors of desire for social distance. [PDF]
Front PsycholIntroductionStigma is associated with psychological distress and can act as a barrier to help-seeking for people who experience gambling harms. While research into intersectional stigma within this population is scarce, this may be exacerbated for those from multiply-marginalised groups.MethodThis study used an online survey with ‘vignette’ design to ...

Independent natural extension for sets of desirable gambles [PDF]
, 2011 We investigate how to combine a number of marginal coherent sets of desirable gambles into a joint set using the properties of epistemic irrelevance and independence.

Credal networks under epistemic irrelevance using sets of desirable gambles [PDF]
, 2013 We present a new approach to credal networks, which are graphical models that generalise Bayesian nets to deal with imprecise probabilities. Instead of applying the commonly used notion of strong independence, we replace it by the weaker notion of ...

Quantum indistinguishability through exchangeable desirable gambles
, 2021 Two particles are identical if all their intrinsic properties, such as spin and charge, are the same, meaning that no quantum experiment can distinguish them. In addition to the well known principles of quantum mechanics, understanding systems of identical particles requires a new postulate, the so called symmetrization postulate. In this work, we show

Desirable gambles based on pairwise comparisons
International Journal of Approximate Reasoning, 2023 This paper proposes a model for imprecise probability information based on bounds on probability ratios, instead of bounds on events. This model is studied in the language of coherent sets of desirable gambles, which provides an elegant mathematical formulation and a more expressive power.
