Aim/Background. Actuarial risk tools are commonly used in corrections and forensic mental health settings. Given their widespread use, it is important that evaluators and decision-makers understand how scores on these tools relate to recidivism risk. Relative risk is one useful metric for communicating an offender's risk of reoffending. Methods. In the current study, risk ratios were computed f...

Reservoir-induced seismicity is a very important issue in the study of geological analysis and ecoenvironmental impact assessment in hydraulic and hydropower engineering. On the other hand, reservoir-induced seismicity is a necessary consideration in the feasibility study of hydropower project. Due to the complexity in the process of reservoir-induced earthquake and the uncertainty of the influ...

Modern MRI measurements deliver volumetric and time-varying blood-flow data of unprecedented quality. Visual analysis of these data potentially leads to a better diagnosis and risk assessment of various cardiovascular diseases. Recent advances have improved the speed and quality of the imaging data considerably. Nevertheless, the data remains compromised by noise and a lack of spatiotemporal re...

We propose the set of operations for querying the conceptual schema of an objectoriented database. The operations form the basis of an algebra for objects called OVAL. They are de ned using the constructs introduced for our formalization of the object-oriented database model. The operations allow a user to query: (i) associations among individual objects, (ii) relationships between individual o...

At the occasion of the 25th European Conference on Operational Research, EURO XXV 2012, July 8–11, 2012, in Vilnius, Lithuania (http://www.euro-2012.lt/), the Central European Journal of Operations Research (CJOR; http://www.springer.com/ business+%26+management/operations+research/journal/10100) invited to submissions of papers to a special issue on Recent Advances in Computational Biology, Bi...

The identification of high-risk patients is a critical component in improving patient outcomes and managing costs. This paper describes the Intelligent Care Delivery Analytics platform (ICDA), a system which enables risk assessment analytics that process large collections of dynamic electronic medical data to identify at-risk patients. ICDA works by ingesting large volumes of data into a common...

When learners have to make sense of risky situations, they can use mathematical models and representations which facilitate successful risk assessment. Based on theoretical considerations on the benefits of specific models and specific representations in such contexts, we present empirical findings of a study which examined whether students use such models and representations in their risk asse...

We address two long-standing survey research problems: measuring complicated concepts, such as political freedom and efficacy, that researchers define best with reference to examples; and what to do when respondents interpret identical questions in different ways. Scholars have long addressed these problems with approaches to reduce incomparability, such as writing more concrete questions—with ...

Given that Micro and Nano Technologies (MNTs) is still an emerging field, it is important to adopt a tool for evaluating the maturity of MNT-based products and the production processes enabling their manufacture. In particular, as a risk assessment tool, it could help both the pace of technological adoption and the successful exploitation of these technologies. In this context, the objective of...

Here we model the price of a stock in discrete time by a Markov chain of the recursive form Sn+1 = SnYn+1, n ≥ 0, where the {Yi} are iid with distribution P (Y = u) = p, P (Y = d) = 1 − p. Here 0 < d < 1 + r < u are constants with r the risk-free interest rate ((1 + r)x is the payoff you would receive one unit of time later if you bought $x worth of the risk-free asset (a bond for example, or p...
