Background and aim: Carotid artery stenosis is one of the major causes of transient ischemic attack (TIA) and acute ischemic stroke (IS), and carotid surgery and stenting are used to reduce the risk of ipsilateral IS. However, the adherence to the recommendation of carotid imaging in clinical practice has not been well studied. We analyzed proportions of carotid imaging and determinants for its no
In this thesis model predictive control (MPC) is used to dynamically optimize a portfolio where the data is sampled every 5 minutes. Previous research has shown how MPC optimization applied to daily sampled financial data can generate a portfolio that exceeds the value of standard portfolio strategies such as Strategic asset allocation. MPC has been found to have a computational advantage when ret
The last two decades, socially responsible investing has emerged such that there is a value in itself to invest responsibly. This paper analyzes the relationship between Environmental, Social, Governance (ESG) and stock returns, and investigate if any of these three individual pillars have a more significant impact during the period 2005 – 2018. The study contributes to the field by applying an ES
The following essays checks whether the Swedish stock market (represented by OMXS30) supports the weak efficiency of the EMH by observing whether the stocks contain a unit root and whether one can use trading strategies to create abnormal profits. The AR(1) model of the stock prices have a unit root coefficient very close to 1, thus they are trend stationary but have a very long memory. This model
Purpose This research aims to deepen the view of willingness to share knowledge within the organization by using the lens of organization-based self-esteem in a case study. Methodology Utilizing an interpretive tradition, especially symbolic interactionism, this research employs a qualitative case study methodology with an abductive approach. The empirical material is gathered through 14 semi-
More and more people are getting into gaming. Mostly young males who identify themselves as gamers. The gaming culture has grown rapidly over the last few years and some of the best gamers in the world can make a living by playing games. Esports is a new field that does not get much attention which makes it interesting to study. The purpose of this study is to increase knowledge about gamers'
In Armenia, women are systematically excluded from political processes and issues related to gender equality and women’s rights are not politically prioritized. In the absence of this prioritization, civil society actors play a vital role in promoting and addressing issues related to women. Inclusion is often promoted as a key element in democratization processes and this study takes a gender pers
Today's network cameras are constantly evolving, giving us higher resolution and higher quality video streams which demands higher capacity data links. In Pan, Tilt, Zoom (rotating) cameras the Slip Ring acts as the single communication link between the stationary and rotating parts of the camera and at the same time enables unrestricted rotation. It is therefore a key component within the cam
Chemical Management Services (CMS), an application of Product Service Systems (PSS) in the chemical sector, attempts to optimise chemical consumption patterns. CMS works by changing the fundamental relationship between chemical suppliers and chemical customers and providing incentives to both to reduce the quantity of chemicals used. CMS is gaining increasing popularity as a tool for cost savings
The purpose of this thesis is to highlight the phenomenon of “Sex for Grades” in Liberian universities as an intrinsically relevant category of study by illuminating the relationships between agency and structures; structures that may be enabling or constraining. We do this by analysing how female students use their tactical agency and apply this to the theory of social navigation, a theory that h
Two studies were performed in this paper. The first study was a method development examining the possibilities to do a serial extraction of lipids, PCB 153, NSAIDs (non-steroidal anti-inflammatory drugs) and selective serotonin reuptake inhibitors (SSRIs) from a single sample. Five different treatments were tested with three replicates from each individual fish. All samples were first freeze-dried
Sverige var först i världen med att kriminalisera köpare men inte säljare av sexuella tjänster 1999. På andra sidan sundet pågick samtidigt en debatt som i mångt och mycket påminde om den svenska. Utfallet blev dock det motsatta och samma år tog Danmark bort de sista resterna av den lagstiftning som kriminaliserat prostitution. Uppsatsen syftar till att jämföra och utvärdera gällande rätt i Danmar
Titel: Är man mer benägen att köpa en tidning om den doftar? – En studie i om doftsättning på tidningar kan öka köpintentionen hos konsumenter.

Drastic emission-reductions are needed to avoid the disastrous consequences of climate change. Flying is one of the highest individual carbon-impact actions. By 2050, the aviation industry’s share on global greenhouse gas emissions is expected to rise by 300 to 700%. An intervention to counteract this development is to reduce flying at universities as they have a critical role in leading sustainab
This project started in space and spacial jetlag, shifted towards SAD and the arctic till it landed to become a unisex watch for small to medium sized wrists. All in all, the amount of work done in the previous briefs have influenced the final result. The final result being an automatic retro-looking watch offered in five different colours as a way to cateer to a multitude of personalities wh
In this thesis we consider a general approach to modeling dependence in extreme values of exchange rates by using copulas. As specific examples the following pairs of currencies are analyzed: Swedish krona to U.S. dollar (SEK/USD), Swedish krona to Euro (SEK/EUR), Swedish krona to British pound (SEK/GBP), Swedish krona to Japanese Yen (SEK/JPY), Swedish krona to Danish krone (SEK/DKK) and Swedish
This thesis examines the evolution of Policy Coherence for Development (PCD) in the EU. The overarching purpose is to give an example of ideational causation in the EU, and concretely, to illustrate how a norm can cause changes to policy and to policymaking. It is argued that the PCD concept is essentially a norm, because it provides a guideline for how to prioritize between differing and often co
A well-developed spatial memory is important for many animals, but appears especially important for scatter-hoarding species. Consequently, the scatter-hoarding system provides an excellent paradigm in which to study the integrative aspects of memory use within an ecological and evolutionary framework. One of the main tenets of this paradigm is that selection for enhanced spatial memory for cache
