Factors that determine the effectiveness of entomopathogenic nematodes in combination with other beneficial soil organisms to control root herbivores

Chiriboga Morales, Xavier ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Belowground ecosystems are inhabited not only by organisms that represent a threat to plants (e.g. root herbivores and pathogens), but also by organisms that provide protection to these antagonists (e.g. entomopathogenic nematodes, mychorrizal fungi and root associated bacteria). Herbivore-induced root volatiles, such as the sesquiterpene E-(β)-caryophyllene, are an indirect defense in...

Conception, synthèse et étude de "tris"-fullérodendrimères et rotaxanes liquides-cristallins

Pieper, Pauline ; Deschenaux, Robert (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Ce travail de thèse est basé sur l’utilisation de l’auto-assemblage de dendrimères liquides-cristallins pour créer des architectures supramoléculaires complexes contenant des éléments isotropes tels que les [60]fullerène (C60) ou des rotaxanes. Le but a été d’étudier l’influence de l’incorporation de ces éléments isotropes sur la formation et la stabilité des...

Controlled and effective interpolation

de Sá Alt, Leonardo ; Sharygina, Natasha (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016INFO009.

Model checking is a well established technique to verify systems, exhaustively and automatically. The state space explosion, known as the main difficulty in model checking scalability, has been successfully approached by symbolic model checking which represents programs using logic, usually at the propositional or first order theories level. Craig interpolation is one of the most successful...

Using testate amoeba community structure and functional diversity to assess the impact of climate changes on ecosystem functioning : finding relevant and convenient tools for bio-monitoring of "Sphagnum" peatlands evolution or recovery

Koenig, Isabelle ; Mitchell, Edward AD (Dir.) ; Le Bayon, Claire (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Human activity and ongoing climate changes have an increasing impact on ecosystems and lead to the loss of several natural habitats. Ecosystems provide functions contributing to human well-being and these functions could be estimated based on a monetary value. Among these ecosystems, wetlands and peatlands are of primary importance, by hosting a specific flora and acting as a carbon sink. Their...

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,...
