Decision-support systems based on artificial intelligence (AI) are increasingly implemented in everyday societal contexts, including high-stakes domains such as finance, medicine, and law. While these systems play an expanding role in shaping important decisions under uncertainty, a fundamental question concerns how algorithmic advice affects the behavior of human decision-makers. Despite this, mo

This study investigates why households' perceived inflation differs from the official inflation in Sweden, measured by CPI, over the period 1994-2025. The analysis is based upon two hypotheses: the first examines whether periods of high inflation are related to a lower gap between perceived- and official inflation. The second examines whether increased media exposure regarding inflation, is li

Diversification reduces portfolio risk when assets are imperfectly correlated, yet evidence suggests that correlations rise in turbulent markets and weaken diversification benefits. This thesis examines whether market volatility undermines sector-level diversification in the Nordic equity market and whether any sector remain resilient. Using daily data for ten Nordic sector indices, the analysis a

This paper analyzes how different types of information affect how the market reacts to earnings announcements. This is done by focusing on short-term price dynamics following earnings announcements explained by EPS Surprise and Sentiment. The market reaction is measured as overnight and intraday abnormal returns. The main findings indicate an immediate overnight reaction associated with both EPS S

Financial markets are subject to sudden changes in volatility, which can challenge standard option pricing models such as Black–Scholes. While the Black–Scholes model remains a widely used benchmark, its assumptions of constant volatility and continuous price movements may limit its performance during turbulent market conditions. This thesis examines whether the Merton jump–diffusion model provide

This thesis investigates whether integrating technical market data with fundamental accounting variables improves the out-of-sample predictability of stock returns in the highly liquid S&P 100 universe. Using an expanding window approach from 2010 to 2024, the study compares the performance of regularized linear (Ridge Regression) and non-linear (Histogram Gradient Boosting) estimators against

This thesis examines how changes in the Swedish policy rate affect sectoral stock returns in the banking, real estate, and service sectors during the period 2012–2024. Using monthly sector-level data and regression-based analysis, we study whether monetary policy has heterogeneous effects across sectors with differing financial structures and interest rate exposure. The analysis covers both the pr

This thesis investigates the use of parton shifting technique facilitated by Monte Carlo methods to preserve causality in relativistic particle simulations, focusing on parton cascade models used in high-energy nuclear collisions. In such simulations, relativistic effects can lead to frame-dependent collision ordering, resulting in causality violations. To address this issue, a parton shifting met

Bakgrund: Lättare psykisk ohälsa, såsom depression och ångestsyndrom, utgör de vanligaste orsakerna till sjukskrivning i Sverige. Tillståndet påverkar ofta individens förmåga att reglera energi, prioritera aktiviteter och hantera krav i vardag och arbetsliv, vilket kan leda till en rubbad aktivitetsbalans. Trots detta är kunskapen om vilka faktorer som särskilt påverkar aktivitetsbalans vid sjuksk

Many theories based on Darwinian evolutionary theory are of particular relevance to family research. The theory of kin selection is not limited to social behavior of animals, but also explains why humans in all cultures and epochs organize their reproductive and productive activities in family networks and family households. Even though the willingness to cooperate in the human family ultimately g

This study investigates the potential of enhancing regional rail efficiency and reducing emissions through the implementation of dual Electric Traction Machine (ETM) drivetrains. By employing two ETMs, optionally with different specifications and real-time load distribution, the research evaluates the impact on energy savings and battery longevity. The analysis is based on a comparative simulation

Acquired diverticula of the small bowel are mainly located in the duodenum, followed by the jejunum. They are typically asymptomatic, but may occasionally cause massive bleeding, diverticulitis, and even perforation. Meckel’s diverticula are a remnant of the omphalomesenteric duct located in the ileum. They can cause overt bleeding, typically in children, but also in adults. Sensitivity of Meckel’

Benign tumours of the small intestine consist of various rare entities such as tumour-like inflammatory or hyperplastic lesions, hamartomas (organoid malformations), ectopic tissues, and true neoplasms of epithelial or mesenchymal origin. These benign tumours often stay asymptomatic for years, with small lesions frequently remaining undiscovered. They may be manifested clinically by bleeding, iron

Objectives: To determine the diagnostic value of disclosing monotypic T-cell populations by expression analysis of the constant region 1 of T-cell receptor β (TRBC1) by flow cytometry, for the detection of T-cell neoplasms, in a routine hematopathology practice setting. Methods: A panel of antibodies ECD-CD16/PECy5.5-CD4/PECy7-CD2/APCAF700-CD7/KO-CD8/FITC-TCRγδ/PE-TRBC1/APC-CD26/APC-CD57/APC-CD30/

Product development faces increasing challenges in today’s fast-evolving environment. Agile has emerged as a promising approach to navigate and succeed under such conditions. Grounded in the values and principles of the Manifesto for Agile Software Development, practitioners have designed agile frameworks and practices that have demonstrated significant benefits in software development. Motivated

BackgroundHeart failure (HF) and arterial hypertension (AH) are strongly associated with obesity, with a linear relationship to increasing body mass index (BMI). However, some individuals with obesity do not exhibit signs of HF or AH.PurposeThis study aimed to compare, for the first time in a large population-based cohort, individuals with obesity who have normal left ventricular function and remo

BACKGROUND: Evidence indicates that artificial intelligence (AI) can improve mammography screening by increasing cancer detection and reducing screen reading workload, but its effect on interval cancers (primary breast cancers diagnosed between two screening rounds or within 2 years after the last scheduled screening that were not detected at screening) is unknown. We aimed to compare the interval

Disorder is an intrinsic feature of all solids, from crystals of atoms to superlattices of colloidal nanoparticles. Unlike atomic crystals, in nanocrystal superlattices, a single misplaced particle can affect the positions of neighbors over long distances, leading to cumulative disorder. This elusive form of collective particle displacement leaves clear signatures in diffraction, but little i
