Modelling a Dynamic Forest FuelMarket Focusing on Wood Chips: A Spatial Agent-based Approach to Simulate Competition among Heating Plants in the Province of Carinthia, Austria. GI_Forum|GI_Forum 2017, Volume 1 |
Sustainability and renewable resources are attracting increased attention in the energy supply sector. This paper elaborates on the application of agent-based modelling methods to simulate forest fuel markets and supply chains. More precisely, it aims to simulate the market for wood chips for heating purposes, based on a sustainable forest growth and yield model, in conjunction with cognitive agents that act in the market. In the agent-based model, three types of agents are defined: forest owners (supply), biomass heating plant (demand), and ‘traders’, connecting supply and demand. Forest enterprises can decide on forest operations based on the state of the forest fuel market – e.g. considering the price for wood chips. Each biomass heating plant has an associated ‘trader’ that tries to fulfil the demand for forest biomass while minimizing the transport distances and the cost for the wood chips. The paper discusses the results of a simulation scenario in the Province of Carinthia, Austria. The simulation results are analysed with respect to space and time concerning biomass transport distance, transport patterns and remaining biomass stock
Critical Infrastructure Analysis (CRITIS) in Developing Regions – Designing an Approach to Analyse Peripheral Remoteness, Risks of Accessibility Loss, and Isolation due to Road Network Insufficiencies in Chile. GI_Forum|GI_Forum 2018, Volume 2|
Modernizing societies become increasingly dependent on critical infrastructures (CRITIS), one of the most important of which is the road network. Road networks are vulnerable to hazards from the natural environment (e.g. extreme weather conditions, seismic and volcanic events, and landslides) and social environment (e.g. intentional attacks, traffic jams, roadblocks). Conversely, road networks impose vulnerability on their social environment (e.g. on people trying to leave disaster zones). Investigating the particular vulnerability of a given road network in order to increase its resilience is crucial for disaster risk reduction by spatial planning. However, in many cases in developing countries, the vulnerability of people still seems more pressing than the vulnerability of CRITIS. This paper develops an approach for investigating road network vulnerability in developing regions, using a Chilean example. However, the approach is sufficiently generic to be applied to comparable situations in other countries

Convergence or divergence of educational disparities in mortality and morbidity? The evolution of life expectancy and health expectancy by educational attainment in Austria in 1981-2006. Vienna Yearbook of Population Research|Vienna Yearbook of Population Research 2010 8|
The continuous increase in life expectancy in developed countries is typically associated with an increase in the number of years in good health, whereas the number of years in bad health rather stagnates. At present relatively little is known about trends in educational disparities in mortality and particularly morbidity. By combining life tables from census follow-up with cross-sectional survey data on self-perceived health, we are able to estimate life expectancy as well as health expectancy differences between three educational groups in Austria in 1981-2006. All educational groups have substantially gained length and quality of life (both absolute and relative) during the last decades. Between medium and low educated females, we observe a significant decrease in the life expectancy difference, but a significant increase in the health expectancy difference. No significant changes in educational differences are found among males. The educational expansion of the population has shifted a large proportion of the population to lower-risk groups
