Subjective Expected Utility Theory with 'Small Worlds' [PDF]
, 2009 We model the notion of a "small world" as a context dependent state space embedded into the "grand world". For each situation the decision maker creates a "small world" reflecting the events perceived to be relevant for the act under consideration. The "grand world" is represented by an event space which is a more general construction than a state ...

On Subjective Probability and Expected Utilities
The Annals of Mathematical Statistics, 1972 The Anscombe and Aumann double relation approach for defining subjective probabilities and utilities in terms of a person's preferences is generalized for the case in which the set of states of the world is unrestricted (finite or not). A monotone continuity condition enables us to prove $\sigma$-additivity; the necessity of this condition is also ...

On the Rejectability of the Subjective Expected Utility Theory [PDF]
The B.E. Journal of Theoretical Economics, 2016 AbstractState space, a key element of the Subjective Expected Utility (SEU) theory, is not observable. This implies that, in order to test the SEU theory, it is necessary to assume some state space. Consequently, if the SEU theory is rejected, then it is appropriate to conduct a robustness check; that is, to search for a different state space and a ...

FEBS Open Bio, EarlyView.Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

Projective expected utility [PDF]
Proceedings of the 12th Conference on Theoretical Aspects of Rationality and Knowledge, 2009 Motivated by classical decision-theoretic paradoxes (Allais 1953, Ellsberg 1961), we introduce a projective generalization of expected utility along the lines of the quantum-mechanical generalization of probability theory. The resulting decision theory accommodates the paradoxes, while retaining significant simplicity and tractability.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Too good to be true: rhesus monkeys react negatively to better-than-expected offers. [PDF]
PLoS ONE, 2013 To succeed in a dynamically changing world, animals need to predict their environments. Humans, in fact, exhibit such a strong desire for consistency that one of the most well-established findings in social psychology is the effort people make to ...

Digital Cognitive Phenotyping for Differential Diagnosis and Monitoring in Neurological Conditions
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To assess the utility, accessibility, and equivalence to supervised scales of online cognitive assessment in older individuals with cognitive impairment. Methods Patients with Alzheimer's disease (AD, n = 31), idiopathic normal pressure hydrocephalus (iNPH, n = 26), and traumatic brain injury (TBI, n = 23) completed online cognitive ...

Subjective Probability and Expected Utility without Additivity [PDF]
Econometrica, 1989 Summary: An act maps states of nature to outcomes: deterministic outcomes as well as random outcomes are included. Two acts f and g are comonotonic, by definition, if it never happens that f(s)\(\succ f(t)\) and g(t)\(\succ g(s)\) for some states of nature s and t. An axiom of comonotonic independence is introduced here.
