Biased Diffusion in Chainlike Fractal Structures: Universal Behaviour [PDF]

Europhysics Letters (EPL), 1988
We study diffusion on topologically linear fractal structures under the influence of a uniform external field. Due to the fractal nature of the chain, the uniform field acts on a random walker like random correlated (local) fields in a one-dimensional chain.

On biasing behaviour to the optimal

1997
A formal framework for synthesizing interactive systems is outlined. A distinction is made between the functional ‘behaviour’ of a system, which is a description of everything that the user is permitted to do, and the ‘use’ of a system, which is what the user is likely to do.

Behavioural Biases in Financial Decision-Making [PDF]

SSRN Electronic Journal, 2016
Behavioral finance is an emerging field of study which is relatively new and having its provenance from decision theory. Behavioral finance is a multidisciplinary research area that combines psychology and finance and investigates the issues that impact the decision-making process and explains the irrational nature of individuals, groups and ...

The Role of Behavioural Factors and Cognitive Biases in Rock Engineering

Rock Mechanics and Rock Engineering, 2021
In this paper, the authors investigate the role that behavioural factors and cognitive biases play in rock engineering. The concept of behavioural rock engineering is herein introduced as the study of rock engineering as it pertains to design decision-making processes made by individuals.

Is optimism optimal? Functional causes of apparent behavioural biases

Behavioural Processes, 2012
We review the use of the terms 'optimism' and 'pessimism' to characterize particular types of behaviour in non-human animals. Animals can certainly behave as though they are optimistic or pessimistic with respect to specific motivations, as documented by an extensive range of examples in the literature.

Biased diffusion in percolation systems: indication of multifractal behaviour

Journal of Physics A: Mathematical and General, 1987
The authors study diffusion in percolation systems at criticality in the presence of a constant bias field E. Using the exact enumeration method they show that the mean displacement of a random walker varies as (r(t)) approximately log t/A(E) where A/(E)=In((1+E)/(1-E)) for small E. More generally, diffusion on a given configuration is characterised by

Decision Making, Belief and Behavioural Biases

SSRN Electronic Journal, 2019
Behavioural finance theories explain "why" individuals exhibit behaviours that do not maximize expected utility. Behavioural finance highlights inefficiencies, such as under- or over-reactions to information, as causes of market trends and, in extreme cases, of bubbles and crashes.

Behavioural Biases and the Pricing-Kernel Puzzle

SSRN Electronic Journal, 2017
The pricing-kernel, when estimated from index options, appears to show risk-loving behaviour for small gains and losses. Although this puzzle could be caused by option buyers using subjective probability-weighting, such weighting generates an unrealistically large (and time-varying) risk-premium.
