Past research has widely regarded trust as unconditionally facilitating behavioral intentions, and perceived risk as unconditionally detracting from them. This study advocates the necessity to examine trust and perceived risk within the broader perspective of the societal context. We propose that the perceived regulatory effectiveness of online marketplaces moderates the impact of trust and ris...

Patients treated at different hospitals often vary in the severity of their pre-operative clinical condition. To fairly compare outcomes at different hospitals, it is necessary to adjust for differences in the case mix of patients across hospitals. CCMRP "levels the playing field" by accounting for the pre-operative condition of each patient. Hospitals that routinely handle complex cases (e.g.,...

In this paper, we propose a customer-arrival-based insurance risk model, in which customers’ potential claims are described as independent and identically distributed heavy-tailed randomvariables andpremiumsare the same for eachpolicy. Weobtain some precise large deviation results for the prospective-loss process under a mild assumption on the random index (in our case, the customer-arrival pro...

We show that a simple mixing idea allows to establish a number of explicit formulas for ruin probabilities and related quantities in collective risk models with dependence among claim sizes and among claim inter-occurrence times. Examples include compound Poisson risk models with completely monotone marginal claim size distributions that are dependent according to Archimedean survival copulas a...

This paper outlines a security assessment methodology for analysing critical infrastructure networks. The focus is on intentional attacks against critical infrastructure, but otherwise the scope is not delimited much. Comprehensive security analysis of a critical infrastructure network requires an assessment of the probability of an attack, the probability of success of the attack, the propagat...
