The US Constitution mandates that a decennial census take place in 2020. It is standard procedure for households that do not mail their response (or complete it online) to be surveyed in person by enumerators hired for this purpose. But the highly contagious SARS-Cov-2 (novel coronavirus) makes...

This paper considers the application of adult learning principles in training learners to operate high risk equipment such that they develop a sense of responsibility and accountability for the choices they make for themselves both during and post training. A literature review was utilised to...

The COVID-19 pandemic has exceeded over ten million cases globally with no vaccine available yet. Different approaches are followed to mitigate its impact and reduce its spreading in different countries, but limiting mobility and exposure have been de-facto precaution to reduce transmission....

Define the riskiness of a gamble as the reciprocal of the absolute risk aversion (ARA) of an individual with constant ARA who is indifferent between taking and not taking that gamble. We characterize this index by axioms, chief among them a “duality” axiom which, roughly speaking, asserts...

It is an undisputed fact that weather risk increases over time due to climate change. However, qualification of this statement with regard to the type of weather risk and geographical location is needed. We investigate the application of novel statistical tools for assessing changes in weather...

Classical asset allocation methods have assumed that the distribution of asset returns is smooth, well behaved with stable statistical moments over time. The distribution is assumed to have constant moments with e.g., Gaussian distribution that can be conveniently parameterised by the first two...

We study Aumann and Serrano's (2008) risk index for sums of gambles that are not dependent. If the dependent parts are similarly ordered, then the risk index of the sum is always larger than the minimum of the risk indices of the two gambles. For negative dependence, the risk index of the sum is...

This paper proposes a method to evaluate if risk is adequately accounted for in the Morningstar rating system. The analysis is based on the comparison between the rating obtained ignoring the risk component and those obtained increasing the weight of risk and, in particular, for the level of...

Probabilistic preference models predict that a subject makes different choices with different probabilities in repeatedly experiments with the same stimuli. This paper explains why. First, we prove that a gamble is a statistical ensemble or sample function of a random field with canonical...
