Transition to retirement and aging : change and persistence of personal identities

Teuscher, Ursina ; Retschitzki, Jean (Dir.) ; Spini, Dario (Codir.)

Thèse de doctorat : Université de Fribourg, 2003.

This doctoral thesis deals with the question of how self-images change when people are getting into the age of retirement. Two main issues are addressed regarding the development of personal identities in that life stage: (1) The content of identity: the question if and how retired people have a different way of defining or characterizing themselves than employed people. (2) The age identity...

Cave Genesis and its relationship to surface processes : investigations in the Siebenhengste region (BE, Switzerland)

Häuselmann, Philipp ; Monbaron, Michel (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; Nr. 1383.

The Siebenhengste region is one of the most significant cave areas in the world. Its high density of cave passages that extend over 1500 m in altitude makes it a key site for the study of Alpine paleogeomorphology and paleoclimatology. The present thesis concentrates on St. Beatus Cave and Bärenschacht at the southern rim of the cave region. The tectonics, hydrogeology, speleogenesis,...

Whispering to the prince : academic experts and national security policy formulation in Brazil, South Africa and Canada

Kenkel, Kai Michael ; Krause, Keith (Dir.)

Thèse de doctorat : Université de Genève, 2004 ; HEI 683.

This thesis posits three sets of factors governing academics' participation in security policy formulation processes at the national level. These are policymaker uncertainty attributes such as specialised knowledge, institutionalised prestige and specific forms of argumentation; and the normative resonance of experts' inputs with policymakers' expectations. The argument follows a triple...

Constrained nonparametric dependence with application in finance

Gagliardini, Patrick ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2003 ; 2003ECO002.

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...

Tracing the decision maker

Schulte-Mecklenbeck, Michael ; Huber, Oswald (Dir.) ; Kühberger, Anton (Codir.)

Thèse de doctorat : Université de Fribourg, 2005.

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...

Hedging and risk measurement for option portfolios

Fierli, Francesco ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2004 ; 2004ECO005.

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 high-resolution stratigraphic architecture and evolution of the Burdigalian carbonate-siliciclastic sedimentary systems of the Mut Basin, Turkey

Bassant, Philip ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 1999 ; no 1256.

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...

Peace enforcement : mapping the "middle ground" in peace operations

McDonald, Glenn Steven ; Abi-Saab, Georges (Dir.)

Thèse de doctorat : Université de Genève, 2001 ; HEI 623.

This dissertation aims to demonstrate that a new type of peace operation, here called "peace enforcement", has been recognized in theory and practice, and to describe its features in detail. As an analysis of UN documentation (chapter 1), selected cases (chapters 2-5) and national military doctrine shows, peace enforcement combines features of both traditional peace-keeping and the kind of...
