BACKGROUND Colorectal cancer (CRC) has a high incidence, especially in New Zealand. The reasons for this are unknown. While most cancers develop sporadically, a positive family history, determined by the number and age at diagnosis of affected first and second degree relatives with CRC is one of the major factors, which may increase an individual's lifetime risk. Before a patient can be enrolle...

The aim of is paper to address the problem identifying critical factors in analysis non-coal mine explosion accidents as well improve rationality and accuracy risk results. Hence, we developed a identification method for accidents, combining Systems-Theoretic Accident Model Process (STAMP) Rank-order Centroid (ROC) based on Poset decision-making theory. proposed was applied identify engineering...

Cyber risks are an important point on the business agenda in every company, but they are difficult to assess due to the absence of reliable data and profound analyses. To improve this situation, we identify cyber losses from an operational risk database and analyze these with methods from the field of actuarial science. Specifically, we apply operational risk models in order to yield consistent...

Lyme disease due to infection with Lyme borreliosis poses an uncertain dynamic threat to the Dutch and their public health system. This risk was used to develop and illustrate two variants of a National Risk Assessment approaches for slumbering/latent risks. This paper explains and illustrates the System Dynamics-based variant using the societal risk posed by Lyme disease. Thousands of plausibl...

Quantitative Risk Assessment (QRA) models have already been developed and used to assess various risks of road tunnels, including the societal risk and expected number of fatalities (ENF). Fire in a road tunnel is considered as the most severe disaster in that road tunnel is an enclosed space. The risk assessment for fire in road tunnels involves a number of parameters. Some of these parameters...

We introduce a generalised subgradient for law-invariant closed convex risk measures on L and establish its relationship with optimal risk allocations and equilibria. Our main result gives sufficient conditions ensuring a non-empty generalised subgradient.

We discuss the uniformly asymptotic estimate of the finite-time ruin probability for all times in a generalized compound renewal risk model, where the interarrival times of successive accidents and all the claim sizes caused by an accident are two sequences of random variables following a wide dependence structure. This wide dependence structure allows random variables to be either negatively d...

drilling operations are exposed to a variety of hazards, some of which may be location and activity dependent and each could pose different risk from different paths.  drilling operation may be vulnerable to hurricanes in one region and be exposed to geohazards in another. however, there are other hazards, (e.g. corrosion, age degradation, poor maintenance), which equally affects every rig. ide...

The objective of this article is to discuss the potential of economic analysis as a tool for identification and evaluation of corruption in legislative acts. We propose that corruption be perceived as a risk variable within the legislative process. Therefore we find it appropriate to employ risk analysis methods, used in various fields of economics, for the evaluation of corruption in legislati...
