This thesis studies the pricing of overnight indexed swap (OIS) caps using a one-factor CIR++ short-rate model with piecewise constant volatility. The model combines a CIR process with a deterministic shift, allowing an exact fit to the initial zero-coupon term structure and thereby enabling the remaining CIR parameters to be calibrated to other market instruments. OIS caplets are priced using Lap
Monitoring animal populations has several purposes in ecological sciences, including the study of animal behaviour, population dynamics and biodiversity. The common guillemot, known in North America as the common (or thin-billed) murre (Uria aalge), is an important indicator species for the Baltic Sea ecosystem. Stora Karlsö, Sweden, is the most prominent breeding location for guillemots in the B
Bakgrund: Ökad skärmtid kan påverka tid för aktiviteter som skola, fysisk aktivitet och sömn samt ge negativa effekter kring delaktighet och välbefinnande. Aktivitetsbalans genom livet är en förutsättning för hälsa och välbefinnande. Ungdomar toppar listan med daglig användning av sociala medier samtidigt som psykisk ohälsa är ett växande problem. Syfte: Att undersöka självskattad aktivitetsbalansBackground: Increased screen time may cause consequences for activities such as school, physical activities and sleep, and negatively impact participation and well-being, while occupational balance is a presumption for health. Youths have the highest social media use, as mental health problems are increasing. Aim: To investigate self-assessed occupational balance and social media use among high sc
Electronic Health Records (EHRs) are central to the digital transformation of healthcare and are intended to support coordination, documentation, and access to patient information across healthcare settings. However, technical interoperability does not necessarily mean that exchanged information is usable in clinical work. This thesis examines how healthcare professionals experience the interopera
L1_0-ordered thin-film FePd was measured using AFM, MFM, TEM, XRR and GISAXS to determine what defects were present and how they affected the X-ray scattering. In AFM it was found that there was a terrace structure, with surface steps going along the <110>-direction. These steps originated in dislocations moving from the Pd-FePd interface to the surface, which could be seen in the TEM. The layer t
Denna studie syftar till att undersöka sambandet mellan studenters användning av stora språkmodeller inom högre utbildning och deras tankar kring användningens effekter på lärande. Genom att ta avstamp i en kvalitativ metod och semistrukturerade intervjuer undersöks ämnet via studenters självrapporterade användning av stora språkmodeller, eventuella tankar kring användningens effekter på lärande s
What would it mean for a building to never be finished? This thesis starts from that question. Looking at informal settlements, specifically the umkhukhu in South African townships , buildings there grow bit by bit, use whatever is available, get taken apart and rebuilt. There is no completion date. The thesis takes that seriously, not as something to fix, but as a way of thinking about what h
Nascent entrepreneurship represents one of the most psychologically demanding stages of the venture creation process. Operating without stable organizational structures, reliable performance feedback, or consistent revenue streams, nascent entrepreneurs are particularly vulnerable to psychological pressures that may determine whether they persist or withdraw. Among these pressures, fear of failure
Syftet med studien var att undersöka om olika batcher av kikärtsmjöl från fabrik hade skillnader i sammansättning, funktionella egenskaper och termiska egenskaper efter proteinextraktion. För att praktiskt utvärdera proteinernas funktionella egenskaper testades de extraherade proteinisolaten även som ersättning för äggula i majonnäs. Två batcher av kikärtsmjöl genomgick alkalisk proteinextraktion
As data generation accelerates globally, organizations accumulate vast amounts of unused information, commonly referred to as dark data. While dark data is widely recognized as holding potential decision value, it persistently remains inaccessible, revealing a paradox between perceived importance and practical neglect. This study examines how organizations in Sweden make dark data accessible for d
Municipalities play a key role in the transition towards sustainable mobility, yet they are expected to reduce transport-related emissions while maintaining accessibility, urban growth and mobility. This study examines how sustainable mobility is problematized in municipal planning and explores the goal conflicts that emerge in the transition towards a more sustainable transport system. Through a
Utvisning är en särskild rättsverkan av brott. Åtgärden kan få långtgående konsekvenser för den enskilde och aktualiserar en konflikt mellan individens rättigheter och statens intresse av brottsbekämpning och allmän säkerhet. I Sverige gäller den europeiska konventionen om skydd för mänskliga rättigheter som lag. Artikel 8 EKMR om skydd för individens rätt till privat- och familjeliv utgör därmed Deportation constitutes a particularly invasive consequence for a criminal offence. Due to the significant effects deportation might cause for the individual, it manifests the conflict between individual rights and the state’s interest in preventing crime and ensuring public safety. In Sweden, the European Convention on Human Rights has the force of law. Consequently, Article 8 of the ECHR, which
Plate heat exchangers are widely used in industry due to their high thermal efficiency and versatility, compact design and ease of maintenance. In gasketed plate heat exchangers (GPHEs), the reliability of the system strongly depends on the adhesion between the elastomeric gasket and the metallic plate. Although GPHEs can be periodically opened and cleaned to restore heat transfer efficiency, cle
Protein containers are hollow protein assemblies with potential applications in drug delivery, nanoreactors, biosensors, and nanoparticle synthesis. Two-component containers are especially interesting because the components can be produced separately and assembled under controlled conditions. However, they are difficult to design, since both the overall container geometry and the interactions betw
Det huvudsakliga syftet med denna studie var att undersöka könsbias i skattningen av ledares ledarskapsförmåga, samt undersöka om könsbias i dessa bedömningar kunde prediceras av deltagarnas grad av sexism. Totalt deltog 136 unga vuxna i Sverige (58.8% kvinnor) i vinjettstudien där de skattade ledare, utifrån en kort text, på fem dimensioner rörande ledarskapsförmåga. Sexism mättes genom Swedish MThe primary aim of this study was to investigate gender bias in the evaluation of leadership ability among leaders and to examine whether these evaluations could be predicted by the participants' degree of sexism. A sample of 136 participants (58.8% women) took part in the vignette study where they scored the leaders, from a short text, across five dimensions regarding leadership ability. Sexi
In the contemporary marketing era dominated by social media, internet memes have emerged as a powerful tool for brands to generate consumer engagement. Memes successfully combine two important entertainment aspects: culture and humour. Whether and how different humour styles lead to greater engagement for brand memes has remained relatively unexplored. Therefore, we investigate this using today’s
In this thesis, we study groups of superpolynomial growth, with a particular focus on the first Grigorchuk group. Introduced by Rostislav Grigorchuk in 1980, this group serves as a fundamental example of a finitely generated group of intermediate growth. The main result concerns the superpolynomial growth of the first Grigorchuk group, illustrating its relevance for the conjugacy search problem a
Female researchers remain visibly under-represented among deep-tech founders in Germany. Although women are present in Science, technology, engineering, and mathematics (STEM) education and early academic research, the founder gap is larger than the pipeline alone would predict, signalling leakage at later, commercialisation-oriented stages of the academic career. This study examines how female re
Greenhouse gases and light-absorbing particles in the atmosphere, including soot, play a key role in climate change. To understand the effect such small particles have on the climate, we first need to understand how they form and how they behave. Soot particles are produced from incomplete combustion processes of hydrocarbons, forming a mixture of graphitic and amorphous structures instead of carb
