Insertion devices have several undesirable effects on the beam dynamics of a synchrotron storage ring, and these must be compensated for in order to ensure long term stable operation. This master’s thesis concerns the two first insertion devices at the MAX IV facility, two in-vacuum undulators for the BioMAX and NanoMAX beamlines. The report presents the work done to neutralize closed-orbit distor
The stochastic volatility (SV) model is an alternative to GARCH models to model time varying volatility. In this thesis the basic stochastic volatility model and three different estimation methods are described---namely, Bayesian Markov chain Monte Carlo (MCMC) methods, quasi maximum-likelihood (QML) and generalized method of moments (GMM). To compare these estimation methods a large scale simul
Since the 1970’s there has been several attempts within the UN at drafting a binding instrument on business and human rights. Up until today, none of the attempts at adopting binding standards have succeeded, with the only successful initiative being the United Nations Guiding Principles on Business and Human Rights – a voluntary set of guiding principles meant to further the respect for human rig
The current study aimed to investigate the relationship between pediatric OCD and three emotion-related constructs; incompleteness, harm avoidance, and disgust sensitivity. Participants were 52 treatment seeking children and adolescents (aged 8-17 years) who were diagnosed with OCD or an anxiety disorder. Data was collected through self-report measures of incompleteness, harm avoidance, disgust se
Development and international relations discourses have for a long-time represented women through dichotomous portrayals, either as liberated Western women or as oppressed Eastern women. The former being the heroic saviour of the latter. The subject of Western women joining the Islamic State, has not only received extensive media attention but proved the dichotomous portrayals of women to be insuf
Women’s representation and participation in the forming of peace agreements are argued to have a positive impact on peace. This paper contributes to a deeper understanding of the necessary preconditions for securing women’s representation at the negotiation table. Through a comparative study in which feminist theory is applied to three cases (Liberia, Nepal, and Colombia) that experienced differen
In industrial circles, in political parties, and in newspapers, there is seldom one reiterating issue that concerns the general public more than the situation of a national economy, as well as how to secure or to undo the practice of it. What is arguably one of the core principals of modern cultures, especially in European societies, not just being a nuclear unit in a bigger economy, but enacting
Entrepreneurship from a neuropsychological approach is certainly a field worth investigating. This dissertation aims to closely investigate the influence of OCD and OCPD traits and behavioral patterns on entrepreneurial decision-making. In the analysis of the study, this paper uses a sample of 11 semi-structured interviews divided between OCD and OCPD entrepreneurs. The closing results of the thes
This thesis investigates the effect of relaxing the assumption of full rationality on a frictional search and matching market with transferable utilities. It has previously been shown that such markets without transferable utilities may exhibit agents searching for a matching partner for longer than optimal due to them overestimating their prospects on the market. Reduced search frictions further
The market of plant based dairy alternatives such as yoghurt alternatives continues to grow as more information on the environmental impact of traditional dairy products become available. The plant-based yoghurt alternatives come with a new set of problems, including longer fermentation times and poor gel structure formation. The aim of the project was to see if fermented yoghurt alternatives coul
Denna kandidatuppsats undersöker kopplingen mellan tre välmåendemått, life satisfaction, psykologisk flexibilitet and psykologisk inflexibilitet och tre kreativitetsmått, kognitiv flexibilitet, originalitet och creative self-efficacy. Huvudhypotesen var att det finns en koppling mellan kreativitet och välmående. Det var en kvantitativ tvärsektionell studie i forma av en enkät. 120 personer svaradeThis thesis investigated the connection between three well-being dimensions consisting of life satisfaction, psychological flexibility, and inflexibility and three creativity measures consisting of cognitive flexibility, originality, and creative self-efficacy. The hypothesis was that there was a connection between creativity and well-being. It was a quantitative study with a cross-sectional desig
Enterprise Risk Management is implemented in various sectors and context. What is really know about ERM and how has the concept progressed parallel to risk research in general? This master thesis investigates some general aspects of ERM and what specific aspects of risk management research is present in current scientific literature. The thesis will consist of a scoping study and a practical imple
Advances in our understanding of hematopoietic stem cells (HSCs) have enabled the establishment of differentiation pathways throughout the hematopoietic hierarchy. To further explore the molecular cues governing cell fate options, there is a need to manipulate gene function in a controllable manner. Gene manipulation systems based on CRISPR activation (CRISPRa) or interference (CRISPRi) could be u
Background: Exercise facilities may have the potential to promote physical activity among residents, and to support an active lifestyle throughout the year. We investigated the association between objectively assessed availability of exercise facilities and objectively assessed physical activity outcomes, and whether time of year had a modifying effect on these associations. Methods: A total of 2,
In epidemiological studies, Helicobacter pylori infection is usually detected by enzyme-linked immunosorbent assay (ELISA). However, infection can spontaneously clear from the mucosa during the progression of atrophy and could lead to substantial under-detection of infection and underestimation of its effect on gastric cancer (GC) risk. Antibodies detected by western blot are known to persist long
The angular distribution of photoelectrons ejected during the ionization of Ne atoms by extreme ultraviolet (XUV) free-electron laser radiation in the presence of an intense near infrared (NIR) dressing field was investigated experimentally and theoretically. A highly nonlinear process with absorption and emission of more than ten NIR photons results in the formation of numerous sidebands. The amp
Background. This study aimed to evaluate Pediatric Appendicitis Score (PAS), diagnostic delay, and factors responsible for possible late diagnosis in children <4 years compared with older children who were operated on for suspected appendicitis. Method. 122 children, between 1 and 14 years, operated on with appendectomy for suspected appendicitis, were retrospectively analyzed. The cohort was divi
While the world's transport energy matrix is still strongly linked to limited and heavily polluting fossil fuels, new markets are appearing for the production and use of alternative transport fuels, such as liquid biofuels. Due to an interconnected global economy, such markets today are developing oil a global scale with actors looking to meet local as well as potential international demand. The a
