Researches kept on focusing on the factors that are directly related to the policyholders to justify the rationale for insurance behaviours. With the city like Hong Kong, which has undergone series of social reforms, it is worthwhile to look at how the concerns over these changes can influence the insurance purchase. Also, factors like service quality and customer relationship in which the policyholders...
It has an important significance to promote the Beijing forestry development and strengthen forest resources management for study on Beijing forest measurement model of risk assessment. This paper has studied on forest measurement model of risk assessment in Beijing used probability regression method. The results show that: Beijing forest fires and forestry production value has a certain relationship,...
DNA adducts have been recognized by many studies as biologically effective dose markers of exposure to carcinogen substances. In this epidemiological study, 194 inhabitants of two Greek cities, Athens and Halkida, are examined in order to investigate the quantitative relationships between exposure of the general population to urban air pollutants such as PAHs and various biomarkers of exposure, susceptibility...
The classical models by Ross and McKendrick have to be revisited in order to incorporate dynamical elements coming from the demography and from the spatial aspects of epidemics. The classical approach is dealing with populations supposed to be constant during the epidemic wave, but the present pandemics show duration during years imposing now to take into account the population growth as well as the...
The health of ecosystem is the hotspot in the field of bionomics. Urban ecosystem, whose health determines directly the continuous development of cities, is the groundwork and carrier of cities' development. In this research, a composite information system of indicators is built in order to evaluate healthy situation of urban ecosystem, and a compound model is designed to evaluate the degree of urban...
This paper investigates the impact of agents' communication on social simulations using the PAX framework. Previous works investigated the impact of structuring elements (e.g. houses, hospitals, roads, etc) on agents' behaviors. This work extends that, by investigating the combined results of different communication schemes and structural costs. To assess the plausibility of application of these ideas...
Malaria vector-anopheles mosquitoes thrive well and transmit the parasite in moisture-laden landscapes in warmer climates. Congested cohabitation of animals and humans, like in agroforestry, near residential areas is ideal malaria ecology. Its afflictions account for high infant mortality and reports of yellow fever; generally in sub-Sahara Africa, and Owerri in particular. Unmanaged land use creates...
Understanding the dynamics of disease spread is of crucial importance, in contexts such as estimating load on medical services to risk assessment and intervention policies against large-scale epidemic outbreaks. However, most of the information is available after the spread itself, and preemptive assessment is far from trivial. Here, we investigate the use of agent-based simulations to model such...
Bioterrorism represents a serious threat to the security of civilian populations. The nature of an epidemic requires careful consideration of all possible vectors over which an infection can spread. Our work takes the SIR model and creates a detailed hybridization of existing simulations to allow a large search space to be explored. We then create a Stackelberg game to evaluate all possibilities with...
With the threat of global bioterrorism, it is necessary to establish a scientific and reasonable system of emergency rescue supplies reserves and distribution, which can be benefit to form an effective emergency logistics network, to shorten the radius of emergency rescue. In the anti-bioterrorism system, a system of emergency service in a supply chain can be formed from the reserve and distribution...
