L'espace de liberté comme mesure synthétique du développement territorial durable
2011
By discussing the concept of development itself, authors propose two synthetic indexes relying on estimation of potential: Development Space Value and Development Space Creation Under the weak hypothesis that any successful development improves future possibilities, changes in potential are a good development measure. In their path, authors show how development space is tied with freedom: a shrink in it results mechanically in indexes fall. So, "sustainable" and "economic" become two sides of same piece rather than enemies. Reliable in simulations, the approach is to be tested in real conditions, to verify full data availability and to secure calculating methods.
Improving statistical classification methods and ecological status assessment for river macroinvertebrates
2016
Aquatic ecosystems are facing a growing number of human-induced stressors and the need to implement more biomonitoring to assess the ecological status of water bodies is eminent. This dissertation aims at providing tools to reduce the costs and improve the accuracy of freshwater benthic macroinvertebrate biomonitoring. To improve the cost-e ciency, we consider automated classi cation and develop a novel classi er suitable for complex macroinvertebrate image data. To enhance the accuracy of macroinvertebrate biomonitoring, we study the statistical properties of the Percent Model A nity index crucial to current Finnish biomonitoring and the factors a ecting these statistics. Finally, we perfo…
The measurement of seasonality for tourism evaluation
2017
Seasonal variations in tourism demand represent one of the most challenging topics in tourism research. After highlighting the main pitfalls which characterize the majority of currently used indices for seasonal amplitude, the present work propose the implementation of a recently discusses a recently proposed index for the measurement of seasonality in tourism, based on the transportation problem approach. An adequate measurement of seasonality is a pre-requisite for the evaluation of the effectiveness of tourism policies aimed at reducing tourism demand imbalance.
