Infectious diseases spread through human networks. Susceptible-InfectedRemoved (SIR) model is one of the epidemic models to describe infection dynamics on a complex network connecting individuals. In the metapopulation SIR model, each node represents a population (group) which has many individuals. In this paper, we propose a modified metapopulation SIR model in which a latent period is taken i...

• Infectious period. The infectious period has been found to be correlated with type and herd size, husbandry practices, and whether the disease is allowed to run its course, or whether controls are applied lesions (Garner, 1992; Donaldson, 1994a; Sanson, 1994; Sellers and Daggupaty, 1990; Willeberg et al., 1994). If depopulation is not applied, the infectious period for cattle can last between...

We consider the spread of an epidemic through a population divided into n sub-populations, in which individuals can move between populations and infectives can only make infections with members of their current population. Attention is focussed upon the effect of the distribution of the infectious period on the probability that the epidemic goes extinction in the limit as the total population s...

A key component of any epidemiological model is the infectious period, which greatly affects the dynamics and persistence of an infection. Social organization, leading to behavioural and spatial heterogeneities among potential susceptibles, interacts with infectious period to create different risk categories within a group. Using the honeybee (Apis mellifera) colony as a social model, a protoco...

We consider the initial invasion of an infectious disease in a finite, homogeneous population. Methodology for evaluating the basic reproduction number, R(0), and the probability mass function of secondary infections is presented. The impact of finite population size, and infectious period distribution (between exponential, two-phase gamma, and constant), is assessed. Implications for infectiou...

Much research has suggested that facial identification has some characteristics of automaticity, in that it is rapid, nonconscious, and mandatory. However, little research has tested whether it can occur even if attention is already devoted to the demanding central processes of another task. In the present study, we addressed this type of automaticity using the psychological refractory period p...
