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...

Detailed protonation experiments of the [5,6]-pinenebipyridine molecule and the unsubstituted [4,5]- and [5,6]-CHIRAGEN[0] ligands in various solvents indicate a variety of structures of the protonated species. UV-visible and NMR measurements (including ¹⁵N chemical shifts) show the transition from trans to cis conformation of [5,6]-pinenebipyridine upon protonation. The...

The enantiomerically pure chiral tris-chelating ligand (+)-(7S,10R)-L(L) comprising three 4,5-pinenobipyridine subunits connected through a mesityl spacer has been synthesized. Complexes of L with RuII and FeII have been prepared and characterised. NMR spectroscopy indicates that...

Based on a large collection of newspaper articles, political discourses, historical inquiries and testimonies, this research analyzes the emergence, development and resolution of the controversy about the "Jewish assets and nazi gold" in the Swiss public sphere between 1995 and 1998. The research starts with the analysis of the emergence of the role of Switzerland during the Second World War,...

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...

Absolute differential elastic and vibrational excitation cross sections have been measured for NO at 135° with resolution of the ²Π1/2 and ²Π3/2 spin-orbit components of the ground electronic term. The electronic fine structure excitation is dominated by the ³Σ⁻ and the ¹Δ resonances of NO⁻, the nonresonant contribution is very small. The cross section is very large, it has about the...
