Partner control mechanisms in repeated social interactions

Wubs, Matthias ; Bshary, Redouan (Dir.) ; Lehmann, Laurent (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Individuals that interact socially regularly have to make decisions whether to help another individual (provide some payoff benefit, possible at a personal payoff cost) or not. Here, a pair of individuals is best off if both individuals help each other, but a single individual may gain a relative payoff advantage by not helping (defecting) while the partner does choose to help, thus creating a...

Evolution of moonwort ferns ("Botrychium", Ophioglossaceae) on local to global scales

Dauphin, Benjamin ; Grant, Jason (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Plants have long fascinated biologists by their ability to form cryptic species, hybrids between distinct species, large and stable genome sizes, and a wide variety of mating systems among taxa that have driven to the current plant biodiversity. More than 450 million year ago, vascular plants emerged and colonized the land. Rapidly, they dispersed to explore new habitats and diversified in...

Les gouvernances territoriales des énergies renouvelables : échelles de planification, décentralisation de la production et conflits d'aménagement dans l'Arc jurassien

Durrer, Patrick ; Rumley, Pierre-Alain (Dir.) ; Matthey, Laurent (Codir.) ; Défago Gaudin, Valérie (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Le développement des énergies renouvelables fait évoluer les pratiques de planification du territoire. Entre les objectifs énergétiques fédéraux et cantonaux, les communes et les régions suisses voient leur développement territorial se transformer. Ce processus est caractérisé par une implication et une opposition citoyenne grandissante. Le cas de Neuchâtel et de l'Arc jurassien...

Complexity of positive contactomorphisms

Dahinden, Lucas ; Schlenk, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

In this thesis we study volume growth properties of positive contactomorphisms, using Rabinowitz-Floer homology. We prove that positive dimensional growth of Rabinowitz-Floer homology implies that every positive contactomorphism has positive topological entropy. We found two instances where Rabinowitz-Floer homology has positive dimensional growth. The first instances are unit cosphere bundles of...

Application of carbon-chlorine isotopic analysis to determine the origin and fate of chlorinated ethenes in groundwater

Badin, Alice ; Hunkeler, Daniel (Dir.) ; Schirmer, Mario (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

Chlorinated ethenes are ubiquitous groundwater contaminants posing a threat to one of our main drinking water sources. Despite their spill history dating back to more than 40 years ago, these contaminants are still found in groundwater in numerous industrially developed countries due to their persistence, difficult characterisation in the subsurface and resulting challenging remediation. When...

An explicit approach to the Baum-Connes conjecture for some semi-direct products

Pooya, Sanaz ; Valette, Alain (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

We investigate the Baum-Connes assembly map through concrete examples. It is known that the Baum-Connes conjecture holds for large classes of groups including a-T-menable groups, thanks to work of Higson and Kasparov. However neither of these works describes the K-groups. In this thesis we describe explicitly the Baum-Connes assembly map for some a-T-menable groups namely BS(1, n), where...

Journalists arguing newsmaking decisions on the basis of anticipated audience uptake : a study of argumentation in the newsroom

Luciani, Margherita ; Rocci, Andrea (Dir.) ; Perrin, Daniel (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018COM006.

This thesis sets out to explore journalists’ anticipatory reasoning on audience uptake, i.e. on the ways in which the audience will react to news. In order to reach this goal, I conduct an argumentative analysis of various types of newsroom activities. The analysis sheds light on journalists’ reasoning processes concerning audience uptake that lead them to broadcast/publish one certain...
