Essays in empirical corporate finance

Yilmaz, Umit ; Plazzi, Alberto (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO006.

I use empirical methods to study the effects of firms' international activities and corporate governance on their operating performance, cost of funding, and credit risk. My studies provide novel evidence on the effects and implications of cross-border borrowing, foreign acquisitions, and governance on firms' financing decision and activities.

Empirical indicators of sentiment are commonly employed in the economic literature while a precise understanding of what is sentiment is still missing. Exploring the links among the most popular proxies of sentiment, fear and uncertainty this paper aims to fill this gap. We show how fear and sentiment are specular in their predictive power in relation to the aggregate market and to...

Reward-related behavioral and biological responses associated with eating : insights from anorexia nervosa and obesity research = Réponses bio-comportementales liées à la récompense: aperçus de la recherche en anorexie mentale et en obésité

Pereira Picolo Ribeiro, Mayron ; Martin Soelch, Chantal (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Research on clinical populations with eating disturbances has shown the involvement of reward processing in the maintenance of disease- associated symptoms. Investigation on food as a reward indicates the metabolic or feeding state (i.e. fasted or fed state) as a modulator of food as a reward, but little is known about how these states influence other types of reward. This is important...

Lattice-based protocols for privacy

Boschini, Cecilia ; Wolf, Stefan (Dir.) ; Camenisch, Jan (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO002.

Privacy and control over data have become a public concern. Simultaneously, the increasing likelihood of the construction of a general purpose quantum computer has led companies and governments to demand for quantum safe alternatives to the protocols used today. New schemes have been elaborated, whose conjectured security against a quantum computer relies on the hardness to solve different...

The Dynamic Reorganization of Cortical Network Interactions during Visual Selective Attention

Pagnotta, Mattia ; Plomp, Gijs (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Visual selective attention prioritizes the processing of behaviorally relevant over irrelevant information, to optimize the use of limited cognitive resources in the brain. These selective mechanisms preferentially route relevant neuronal representations through a network of distributed brain regions. Previous studies suggested that selective information routing in the attention network may...

Living the prison : An ethnographic study of indefinite incarceration in Switzerland

Marti, Irene ; Hertz, Ellen (Dir.) ; Hostettler, Ueli (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2020 ; TH 2820.

During the first half of the 20th century, rehabilitation served as the main paradigm for criminal policy in Switzerland, as in most so-called Western countries. However, changing demands for security and public pressure over the past decades have led to a shift towards a more punitive and hard-line approach to crime. This ‘punitive turn’ in criminal policy has produced more investment...
