The Mathematical Modelling Of The Ross River Virus Transmission, Yoon-Hong Choi
The Mathematical Modelling Of The Ross River Virus Transmission, Yoon-Hong Choi
Theses: Doctorates and Masters
Ross River virus is one of the most severe communicable diseases in Australia. During the 1995/96 outbreak of Ross River virus in south-western Australia, over 1 ,300 human cases were reported. Since the symptoms of the disease are sometimes too weak to be diagnosed, it is important to determine the number of humans who actually contracted the virus during outbreaks. To do this, several mathematical models with different hypotheses are constructed and analysed mathematically. The threshold mathematical conditions of these models suggest that as well as the size of the vector mosquito population, the population size and length of viraemia …
Maritime Resource Exploitation In Southwest Australia Prior To 1901, Paul R. Weaver
Maritime Resource Exploitation In Southwest Australia Prior To 1901, Paul R. Weaver
Theses: Doctorates and Masters
This ethnohistorical study identifies maritime resources of southwest Australia which were subject to human exploitation prior to 1901 and provides an overview of how, when and why this took. place by integrating historical, archaeological, ethnographic, and natural-science information. The resources included for discussion arc whales, seals, seabirds, guano, oysters and pearls, and fish. An argument is developed that the socio-spatial relationship which existed between peoples and marine• estuarine species in the region was determined by the physiography and climate. This relationship has always been imperfect, if not chaotic because of the unpredictability of the resources through long and short term …
