In the first part of this work we address the problem of parameter misspecification in a generic class of stochastic volatility models. We extend the approach proposed by Avellaneda, Levy and Paràs (1995) (hereafter ALP) by moving from a framework with uncertain volatility to the uncertainty on volatility process parameters. We assume that parameter values of the stochastic volatility model are...

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...
