We describe a failure of standard extremal models to account for a catastrophic rainfall event in the coastal regions of Venezuela on 14–16 December 1999, due both to inaccurate tail modelling and to an inadequate treatment of clusters of rare events. We investigate this failure, using a Dirichlet mixture model to approximate a form of moving maximum process that should provide accurate models ...

Construction project losses can often be associated to information failures caused by poor coordination between the multi-disciplinary organisations that deliver them. Information failure could include late, inaccurate, inadequate and inconsistent information. 4D Construction Sequencing Models (CSM) seek to improve the coordination of design, plant, equipment and labour through the visual repre...

Previous research has shown that certain interviewer behaviors can evoke inaccurate answers by children. In the current study, we examined the effects of approving and disapproving statements on the accuracy of 3 children's answers to questions in an interview (Experiment 1). We then evaluated 3 questioning techniques that may be used by interviewers during a forensic interview in which a child...

The Internet has changed how patients with cancer learn about and cope with their disease. Newly diagnosed patients with cancer often have complex educational and informational needs related to diagnosis and treatment. Nurses frequently encounter time and work-related constraints that can interfere with the provision of patient education. They are challenged to educate patients in an environmen...

Batesian mimicry, the resemblance of palatable organisms to an aversive model, is a well documented phenomenon in biology. Resemblance to the model, however, frequently seems to be inaccurate for unknown reasons (Edmunds, 2000). Recently, Johnstone (2002) modelled a scenario where kin selection can lead to the evolution of inaccurate mimics. The model assumes that if mimics are relatively frequ...
