The developments of financial theory in the last decades have shown that one of the most fundamental topics in Finance is the specification of dependence between different risk variables. Empirical evidence on financial time series (such as returns, interest rates, or exchange rates) as well as recent developments in risk management (such as the analysis of dependence between default risks of...

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...

New perspectives of urban marketing suggest to build network strategies to improve cities attractiveness. Isolated quantitative researches cannot represent the multidimensional urban value. So this research, applied to the case of the Lugano area, use a basic qualitative factor of the urban value: stakeholders perception analysis in order to evaluate strengths and weakness, opportunities and...

Ligand field theory has been used along decades with success to describe ground and excited electronic states originating from dn transition metals complexes. Experimental chemists use such a theory to interpret spectra. On the opposite side, computational chemists can describe with good accuracy the ground states properties but models to calculate excited states properties are still being...

Phenotypic plasticity and genetic differentiation of the annual weed Senecio vulgaris L. from ruderal and agricultural habitats were investigated to evaluate the implications for its biological control with the rust fungus Puccinia lagenophorae Cooke using the system management approach. Weed demographic studies are a prerequisite to any weed control strategy. The population dynamics of S....

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...

To cope with the daily changes in their environment, in organisms, from cyanobacteria to humans, endogenous clocks have evolved that anticipate these changes and synchronize physiology and behavior accordingly. In mammals, the central circadian pacemaker is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. From there subordinated cellular clocks in the peripheral organs are...

This dissertation addresses three fundamental problems, which have to be handled in application domains like ubiquitous computing and Web services. The three problems heterogeneity, static configuration, and dynamic configuration are not only considered to persist during the near future but to increase, as similar application domains will emerge. The heterogeneity problem is defined and examples...
