The Earth's climate system is highly nonlinear: inputs and outputs are not proportional, change is often episodic and abrupt, rather than slow and gradual, and multiple equilibria are the norm. While this is widely accepted, there is a relatively poor understanding of the different types of nonlinearities, how they manifest under various conditions, and whether they reflect a climate system...

This thesis focuses on two themes: a methodological and a decision making one. The methodological part introduces the development of a computerized information search tool. The program, called WebDiP (Web Decision Processes), enables the researcher to track participants while they are searching for information in a database. An experiment can be done either in the laboratory or on the Web. The...

The factors influencing the production and deposition of carbonate sediments are known. These are namely accommodation variations (eustasy and tectonics), siliciclastic sediment input, environmental changes (temperature, salinity, trophic level), nature of the producing ecologies, and the hydrodynamic regime. However, the manner in which these factors integrate through time to produce the...

The Jura Molasse, in which most remains of the studied Rhinocerotoidea remains were found, constitutes a well preserved distal part of the Molasse Basin. This sedimentary series covered a major part of the Jura chain during the Oligocene and Miocene. Today, it is only sporadically found trapped in valleys or preserved in karst fillings. During the Oligo-Miocene period, the Jura region was...

The winter ascending circulation of air throughout an accumulation of coarse slope sediments (the so-called chimney effect) facilitates the cooling of the ground and even the occurrence of permafrost in the lower part of a deposit. Simultaneously, any freezing is unlikely to occur in the upper part. The chimney effect has been reported to date mainly for cold and sometimes perennially frozen...
