This thesis investigates whether firm-level innovation predicts both stock returns and future profitability among Swedish listed firms, an area that remains underexplored and inconclusive despite its growing importance. Using patent-based measures of innovation, I analyze the impact through portfolio analysis and Fama–MacBeth regressions. The results show that innovation is positively associated w
This thesis investigates whether portfolios constructed from over 8000 recommendations from analyst companies operating in Sweden (2019-2024), outperform their benchmarks and generate abnormal returns in excess of common risk factors. Four of the six analyst-driven portfolios outperformed their respective indices in cumulative returns, but factor model explained most of the excess performance. Not
This paper aims to comprehensively examine the impact of global climate change, particularly how climate change and the natural disasters it triggers affect the insurance sector in Asia and Europe and the stock market performance of reinsurance companies in both Asia and Europe. Using an appropriate event study methodology, the study investigates the impact of two natural disasters in China and tw
Den reflekterande delen av mitt examensarbete på masterutbildningen i kyrkomusik handlar om hur jag som organist har användning för min blockflöjt – hur jag kan utveckla mitt orgelspel genom att spela blockflöjt. Eftersom jag upplevde att mitt orgelspel förbättrades när jag började spela blockflöjt på allvar, har jag jämfört de båda instrumenten utifrån områdena artikulation, andning, intonation oI have written my thesis about how I as an organist can use the recorder – how I can develop my organ skills by playing the recorder. My experience is that my ability to play the organ improved as I went back to playing the recorder seriously. That is why I have compared the instruments in articulation, breathing, intonation and ensemble and reflected upon what I can take with me and translate fro
This study investigates the influence of polypropylene fibres (PF) on concrete performance across a finely resolved dosage spectrum (0.0–2.0% by cement mass, in 0.1% increments) using 2,100 laboratory specimens. The experimental programme evaluated compressive strength, tensile strength (flexural and splitting), modulus of elasticity, and water penetration depth. Predictive modelling was conducted
The standard assessment of mental health typically involves clinical interviews conducted by highly trained clinicians. While effective, this approach faces substantial limitations, including high costs, high clinician workload, variability in expertise, and a lack of standardization. Recent progress in large language models (LLMs) offer a promising avenue to address these limitations by simulatin
Developing a robust decision analysis framework for selecting appropriate building envelope assemblies is essential to ensure moisture safety, energy efficiency, and sustainability. Recently, Bayat Pour et al. introduced the inutility decision analysis (IDA) method, which integrates moisture safety criteria with sustainability considerations, including economic and environmental aspects. This stud
OBJECTIVE: To evaluate if opioid-free anaesthesia (OFA), is non-inferior to standard of care (SOC), in patients at low risk for acute postoperative pain (APOP).DESIGN: Patient- and assessor-blinded, non-inferiority, randomised, controlled trial.SETTING: Single centre between March 2022 to February 2024.PATIENTS: 154 adult patients, ASA I - II, planned for elective laparoscopic surgery and risk-cla
Thirty years on, gender mainstreaming is still a dominant strategy for working with gender equality, even though its effectiveness is debated. This is also the case in Sweden. This study focuses on how organisations in public administration, particularly municipalities and regions, are introduced to and approach gender mainstreaming.

Understanding vegetation sensitivity to hydroclimate factors, especially how carbon and water cycles respond to climate change, is crucial for assessing ecosystem vulnerability. However, the seasonal sensitivity of carbon and water fluxes to temperature, radiation, soil water content, and vapor pressure deficit across diverse biomes and climates remains unclear. Here, we use 196 eddy covariance ob
Vegetation demographic models (VDMs) are advanced tools for simulating forest responses to climate and land-use changes, and are essential for projecting carbon cycling and large-scale forest management strategies. Despite their increasing incorporation into Earth System Models, VDMs differ in their demographic assumptions, with no prior quantitative comparison of their performance. We benchmarked
Disturbances play a key role in forest dynamics globally, with various effects on productivity. Tree diversity is expected to attenuate the negative impact of disturbance on forest productivity, but its overall effect has been little explored and might depend on the functional composition. Here, we analysed whether forest productivity responses to disturbances were modulated by structural and func
Multiple studies have demonstrated that cancer cells with microsatellite instability (MSI) are intolerant to loss of the Werner syndrome helicase (WRN), whereas microsatellite-stable (MSS) cancer cells are not. Therefore, WRN represents a promising new synthetic lethal target for developing drugs to treat cancers with MSI. Given the uncertainty of how effective inhibitors of WRN activity will prov
Homologous recombination (HR) is an important route for repairing DNA double-strand breaks (DSBs). The early stages of HR are well understood, but later stages remain mysterious. In this issue of Genes & Development, Hustedt and colleagues (pp. 1397–1415) reveal HROB as a new player in HR required for recruitment of the MCM8–9 complex, which is paralogous to the MCM2–7 replicative helicase. HR
