1. Stopover behaviour in migratory songbirds: timing, orientation and departures
Sammanfattning : Songbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds.

2. Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding
Sammanfattning : Most seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. LÄS MER
3. Creating and Probing Extreme States of Materials : From Gases and Clusters to Biosamples and Solids
Sammanfattning : Free-electron lasers provide high intensity pulses with femtosecond duration and are ideal tools in the investigation of ultrafast processes in materials. Illumination of any material with such pulses creates extreme conditions that drive the sample far from equilibrium and rapidly convert it into high temperature plasma. LÄS MER
4. Job Loss: Consequences and Labor Market Policy
Sammanfattning : Essay I: This paper takes a novel approach to estimating the effects of involuntary job loss on future earnings, wages and employment. Whereas the previous literature has relied on mass layoffs and plant closures for exogenous variation in displacement, I use the fact that who is laid off is often determined by a seniority rule, specifically the last-in-first-out (LIFO) rule.

5. Pilots’ decision-making, emotions and cognitive performance in simulated environments
Sammanfattning : The aim of this thesis is to investigate pilots’ performances in distinct simulation environments as related to the phenomena of cognition, emotion and fatigue. By doing so, it provides psychological material to broaden the understanding and possibility to development of pilots’ non-technical skills category related to the operational context. LÄS MER
