Chapter 1 Stochastic Epidemic Models

open access: yes, 2019
This first chapter introduces some basic facts about stochastic epidemic models.We consider the case of a closed community, i.e. without influx of new susceptibles or mortality.

Mapping of Former Strategies and Future Needs for Regulatory Prevention of Skin Sensitization: Cosmetic Products

open access: yesContact Dermatitis, EarlyView.
This study identified multiple areas for improvement in the regulatory risk assessment process. Conclusions based on predictive sensitization data should be made with caution, read‐across data from known sensitizers should be utilized, and epidemiological and patient threshold data should be prioritized in decision‐making.

Modeling and Analysis of Epidemic Diffusion with Population Migration

open access: yesJournal of Applied Mathematics, 2013
An improved Susceptible-Infected-Susceptible (SIS) epidemic diffusion model with population migration between two cities is modeled. Global stability conditions for both the disease-free equilibrium and the endemic equilibrium are analyzed and proved ...

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

open access: yesThe Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Distance learning model and Web Simulation

open access: yes, 2000
In this paper we present a WEB-based didactical simulation system that can be integrated in distance training and learning systems. It represents an innovative way of thinking to learning “by doing” models cutting down reaction time in facing and solving

The big impact of small change: Fresh estimates of English wheat market integration, 1693–1893

open access: yesThe Economic History Review, EarlyView.
Abstract Using existing and new price data sets, we provide the first estimates of market integration across England over the entire 200 years of the industrial revolution. We document a significant, though not huge, integration improvement for markets furthest from London. Full integration was achieved by the 1830s. Our price data sets vary in quality

A comparative study of simulation-based inference methods for epidemic models with identifiability considerations.

open access: yesPLoS Computational Biology
Epidemic models play a critical role in understanding transmission dynamics, generating forecasts, and informing public health interventions when they are properly calibrated to epidemiological data.
