Conflicts of interest in initial public offerings

Pratobevera, Giuseppe ; Degeorge, François (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO003.

In my thesis I investigate the conflicts of interests between underwriters, issuers, and investors in initial public offerings (IPOs). I provide empirical evidence that conflicts of interest exist, affect the IPO process, and have real monetary costs for IPO issuers. The novel data, methodologies, and identification strategies used in this thesis allow answering questions so far unexplored by...

The ageing society : analyzing the coverage of the population ageing in a Belgian quality newspaper

Torben-Nielsen, Karen ; Russ-Mohl, Stephan (Dir.) ; Suggs, Suzanne (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016COM010.

This study has examined how the ‘Ageing Society’ -a society with a rapidly ageing population, a growing share of older persons and a decreasing share of younger persons- and its implications for the Belgian population are represented in the Belgian quality newspaper De Standaard (2011-2013). As such, the study delivered first-time Belgian empirical findings about the coverage of the...

Building global and scalable systems with atomic multicast

Benz, Samuel ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO003.

The rise of worldwide Internet-scale services demands large distributed systems. Indeed, when handling several millions of users, it is common to operate thousands of servers spread across the globe. Here, replication plays a central role, as it contributes to improve the user experience by hiding failures and by providing acceptable latency. In this thesis, we claim that atomic multicast,...

Fabrication and characterization of MEMS alkali vapor cells used in chip-scale atomic clocks and other atomic devices

Karlen, Sylvain ; Mileti, Gaetano (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Atomic clocks are timekeeping devices that can achieve extreme performance in terms of stability and accuracy. Behind this name, hides a variety of different systems which size and complexity can be considerably different depending on their applications. The primary frequency standards used for the realization of the second and the clocks mounted on the Galileo satellite positioning system are...

Relative wage mobility : A new semi-nonparametric estimation method

Naguib, Costanza ; Maggi, Rico (Dir.) ; Gagliardini, Patrick (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO002.

The study of wage dynamics over time is more insightful than the analysis of point-in- time inequality measures. In policy-making, indeed, low wage careers instead of low- wage jobs should be at the center of the debate on long-term wage inequality. Many previous studies tried to estimate the degree of wage mobility within an economy; however, they rely on some quite restrictive assumptions....

The role of alpha-tocopherol in the protection of tomato plants against abiotic stress

Spicher, Livia ; Kessler, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

The ability of energy conversion by the photosynthetic machinery under stress and its capacity to adjust to an ever-changing environment is crucial for plant survival. The photosynthetic light reactions occur at the photosystems in the thylakoids of chloroplasts. The photosystems are composed of proteins in a specific lipid environment. It includes not only membrane lipids but also lipophilic...

Moving towards the understanding of dynamic human face processing

Richoz, Anne-Raphaëlle ; Caldara, Roberto (Dir.)

Thèse de doctorat : Université de Fribourg, 2018.

The human visual system is steadily stimulated by dynamic cues. Faces provide crucial information about identity, gender, ethnicity, speech, attention, eye-gaze direction, or emotions, all important for adapted social interactions. From an evolutionary perspective, humans have been more extensively exposed to dynamic faces, as static face images have only appeared recently with the advent of...
