Adjustments of levels of cooperation in cleaner wrasse "Labroides dimidiatus" : the effects of an audience and satiation

Pinto, Ana Isabel ; Bshary, Redouan (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

Cooperation, the mutual helping between unrelated individuals, is an evolutionary puzzle. This is because helping is often an investment that must yield future benefits in order to be under positive selection. Generally, natural selection favours individuals that perform self-serving behaviour, and hence cheating is a major conceptual issue. However, examples of cooperation are abundant in...

Estimation of a counterfactual wage distribution using survey data

Anastasiade, Mihaela-Cãtãlina ; Tillé, Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Wage discrimination based on gender is a debated topic nowadays. While wage discrimination is prohibited by the Universal Declaration of Human Rights, studies show that women are systematically paid less than men. Wage discrimination is defined as the fact that two groups sharing the same characteristics and performing the same tasks are paid differently. However, this definition is not easy to...

Oxidative stress as a life history constraint : pespectives from a bat species with alternative reproductive tactics

Meniri, Magali ; Helfenstein, Fabrice (Dir.) ; Fasel, Nicolas (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

In this thesis, I investigated the role of oxidative stress (OS) as a constraint for life history traits, using Seba’s short-tailed bats (Carollia perspicillata) as a model species. In this species, males exhibit three alternative reproductive tactics having unequal pay-offs, and whose acquisition could be impacted by early life conditions. First, I studied the effect of OS as a...

Ethnic discrimination in the Swiss labour market - Ethnic hierarchies in correspondence test results

Zschirnt, Eva ; D'Amato, Gianni (Dir.) ; Bonoli, Giuliano (Codir.) ; Haagensen, Arnfinn (Codir.) ; Rich, Judy (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

As a part of the NCCR on the move’s individual project on “Discrimination as an obstacle to social cohesion”, this dissertation focuses on the discrimination of ethnic minorities in the Swiss labour market. Since discrimination is no longer an overt and thus easily observable phenomenon, research on discrimination, and especially on discrimination in hiring decisions has become more...

BABA in priming tomato for enhanced tolerance to drought, salinity and fungal stress and combinations thereof

Ben Rejeb, Ines ; Mauch-Mani, Brigitte (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Tomatoes are among the most produced and consumed vegetable-fruit in many countries and is considered an economically important crop. However, drought, salinity and pathogen infection are the main causes of crop yield reduction and variability. Although plants have developed defensive capacities against these stresses, but plant tolerance and resistance depend on the degree and intensity of...

Ramsey spectroscopy in a Rubidium vapor cell and realization of an ultra-stable atomic clock

Gharavipour, Mohammadreza ; Mileti, Gaetano (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Various application fields in industry, telecommunication, navigation and space demand reliable, compact, high-performance frequency standards with a stability level of −14 at 105s (equivalent to <1ns/day). Thanks to semiconductor technology, optical pumping technique with a laser has opened up new schemes based on laser-microwave double-resonance (DR), such as...

The impact of official development assistance on the donor's economy : the case of Switzerland

López, Luciano ; Zarin-Nejadan, Milad (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018 ; 2696.

This thesis investigates the impact of Official Development Assistance (ODA) on the donor's economy in the case of Switzerland. As a first step, chapter 1 discusses a flow-of-funds approach to quantify the impact of bilateral and multilateral ODA on the donor country's economy. The simple yet rigorous methodology employed allows to compute both, the primary (immediate) and the final impacts of...

Improvement of quality of life through adaptation ? : A qualitative longitudinal approach on households in precarious prosperity in three european countries

Sieber, Rebekka ; Suter, Christian (Dir.) ; Budowski, Monica (Codir.) ; Bonvin, Jean-Michel (Codir.) ; Maeder, Philippe (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

The present study investigates adaptation to precarious prosperity through linking quality of life research with social inequality research. The focus is on households in a specific socioeconomic position termed precarious prosperity. These households struggle to maintain a degree of secure prosperity and are a concern addressed by researchers and policy makers. The topic of adaptation is...

Geogenic arsenic in groundwater of Burkina Faso

Bretzler, Anja Maria ; Schirmer, Mario (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

In the semi-arid West African Sahel belt, rural populations often rely on groundwater from fractured aquifer systems for their drinking water needs. Recent evidence has shown that some tube wells in northern Burkina Faso are affected by arsenic (As) concentrations above the World Health Organisation’s (WHO) 10 μg/L guideline value. Arsenic is hypothesised to stem from geogenic (naturally...
