A new and more comprehensive estimation method for stock-production models is proposed, to provide more reliable stock assessment when data availability is limited. Using difference equations to implement a non-equilibrium production model, the new approach (named POEEM, for Process and...

Objectives: Increase in height in modern societies has been accompanied by an in increase in lifespan. The longer lives of taller people suggest that good nutrition during childhood, together with freedom from recurrent minor infection, prolong human life. There is, however, a caveat. Tall adult...

Biodynamic models may: (i) represent understanding of how the body moves (i.e., ‘mechanistic models'), (ii) summarise biodynamic measurements (i.e., ‘quantitative models'), and (iii) provide predictions of the effects of motion on human health, comfort or performance (i.e., ‘effects...

Zooplankton mortality in plankton population models is often represented by the so-called closure term. Recently, much attention has been paid to the choice of functional form used for the closure term, primarily due to the influential paper by Steele and Henderson (J. Plankton Res., 14,...

In public health studies, it is common for exposure status to be misclassified. In this dissertation, statistical models to adjust for misclassification will be proposed to address four related questions of interest.The first question focuses on exploring the association between a disease and...

Urban watershed managers frequently must address alternative policy goals; flood control and ecological risk reduction. This study combines hydrologic models of flood control and biotic models of ecologic risk with economic models of willingness-to-pay and psychological models of risk processing...
