This study considers a delayed biological system of predator-prey interactions where the predator has stage-structured preference. It is assumed that the prey population has two stages: immature and mature. The predator population has different preference for the stage-structured prey. This type of behavior has been reported in Asecodes hispinarum and Microplitis mediator. By some lemmas and me...

Studies of households have shown a poor perception of natural disaster risks and potential disaster severity, typically overreacting to a disaster event but underpreparing and underinsuring after periods of quiet. Many estimates of disaster response and their economic impacts haven’t taken these sub-optimal household perceptions into consideration. Here I build a model of a coastal community to...

An important healthcare problem in the United States of America is that of emergency department overcrowding. A plausible explanation for such overcrowding is that the lack of access to primary care, which may be influenced by one’s insurance status, leads to greater use of emergency departments. Additionally, it has been suggested that the inappropriate use of emergency departments, along with...
