This thesis investigates minority magnon excitations, firstly proposed by T. Skovhus and T. Olsen (Phys. Rev. B 110.16 (2024)), in the half-filled Hubbard model on the two-dimensional Lieb lattice. Starting from the mean-field ground state with finite Hubbard interaction, we find the splitting Hubbard bands with ferrimagnetic features and identify gapless Goldstone and gapped Higgs magnon modes wi

The study describes and analyses the legal requirements under EU law (General Data Protection Regulation (GDPR) and the European Health Data Space (EHDS)) for artificial intelligence (AI) processing (primary use) of data concerning health within the healthcare sector. Under the GDPR, processing data concerning health, a special category of personal data, requires a legal basis (Article 6 GDPR) and

This thesis investigates the determinants of share repurchase size among Swedish listed firms, focusing on how firm characteristics and ownership structures influence buyback behavior. Using panel data from 2014 to 2024 and applying Tobit regression models, the study finds that firm size has a consistently positive but diminishing effect on repurchase size. Our model incorporates firm-level financ

This thesis conducts a comparative analysis of algorithmic management in the food delivery platform sector, focusing on platforms operating in the United Kingdom and Sweden. Drawing upon Institutional Theory, Labour Process Theory and Discourse Analysis, the study investigates how platforms such as Uber Eats, Deliveroo, Foodora and Wolt implement, regulate and communicate algorithmic control in di

The lithium extraction sites are rapidly expanding to meet the rising demand for lithium-ion batteries, primarily for electric vehicles and renewable energy storage. Serbia has emerged as a key European frontier due to the country’s significant lithium reserves, particularly in the Jadar region. This thesis critically examines how the controversial Jadar lithium mining project is discursively legi

This paper explores whether public debt and associated media coverage affect stock market volatility in Sweden, the United States and the United Kingdom. Using monthly data from January 2004 to March 2025, GARCH(1, 1) models with explanatory variables are estimated to test two hypotheses derived from earlier research. One finding indicates that an increase in public debt reduces stock market volat

This thesis examines the impact on national employment levels in Sweden of reducing the standard workweek from 40 to 35 hours, using 2015 as the analytical baseline. Through rigorous analysis of employment data, productivity metrics, wage effects, unionization rates, and capital substitution patterns, the research employs sectoral comparisons to identify differential effects across the Swedish eco

The study focuses on how Sweden addresses CBRNE-(Chemical, Biological, Radiological, Nuclear, Explosives) associated risks. A changed security environment has seen an intensive increase in CBRNE-associated risks. The aim of the study is to analyse and compare Swedish and international strategies to suggest improvements for Sweden's CBRNE preparedness, particularly in relation to the emergency

This thesis investigates the representation of Roma women in Romanian media through a multimodal critical discourse analysis of newspaper articles, televised news segments, and public discussion board comments in relation to an infamous 2023 case, where a deaf-mute Roma woman gave birth in the courtyard of a hospital after being refused a bed by the medical staff. Drawing on theories of Orientalis

Victim-blaming discourse is not merely a superficial issue, it is a deeply entrenched issue that has its roots in Cambodian society as a whole. The patterns of blame culture not only reinforce cycles of normalizing gender-based violence and prevent victims from accessing justice but also systematically undermine faith in the justice system. This thesis aims to address significant barriers that hin

Med ett rikt forskningsläge om fördelarna med att inkludera matematikhistoria i undervisning är det intressant att undersöka i vilken utsträckning som matematikens historia faktiskt genomsyrar matematikundervisningen. Med bakgrund i detta har examensarbetets syfte varit att undersöka inom vilka delar och på vilka sätt som matematikhistoria framställs i matematikläroböcker på gymnasiet. Frågeställn

Klimatomställningsplaner i fastighetssektorn: pappersprodukt eller styrmedel för verklig förändring? Vad krävs egentligen för att ett företag inte bara ska prata om hållbarhet, utan faktiskt börja agera? I takt med att EU skärper kraven på företagens hållbarhetsrapportering, tvingas många att gå från ord till handling. En viktig del av den nya lagstiftningen är kravet på så kallade klimatomställnSince the Industrial Revolution, human activity has driven major changes in the global climate through increased greenhouse gas emissions. To address this, the EU has introduced several regulatory instruments, including the CSRD and the accompanying ESRS, which require companies to report on environmental and social impacts, risks, and opportunities. As part of these obligations, companies are req

This thesis explores whether the EU’s newly launched Citizens’ Engagement Platform (CEP) can enhance young people’s intention to participate in representative democracy and whether it reinforces or challenges the EU’s liberal demoi-cratic model. Workshops with Swedish upper secondary school students, developed and analyzed using Ajzen’s Theory of Planned Behavior, served as the empirical basis. Fi

Peripheral regions experience difficulties competing against core-regions competitiveness. Although studies have proposed that innovation is an aspect peripheral regions could focus on to combat this inequality, many innovation strategies are developed for urban core-regions and are not applicable on peripheral regions to the same extent. Earlier research has shown that peripheral regions benefit

The main goal of this thesis is to examine the causal effect of the hybrid war with Ukraine beginning from 2014 on Russian export of services towards its main services importers in Belarus, Kazakhstan, China, Cyprus, Switzerland, Germany, United States of America, United Kingdom, Türkiye in years 2006-2020 with the execeptions of 2010 and 2011 due to data limitations. This is done employing a syth

This study examines how firms acquired in leveraged buyouts (LBOs) by private equity (PE) firms manage financial stability during macroeconomic turbulence by using investment as proxy. In an LBO, the acquisition is typically financed with substantial debt, which is placed on the balance sheet of the target firm, resulting in high leverage. A staggered Difference-in-Differences design is employed u

This thesis investigates the determinants of net interest margins (NIM) among Swedish banks during the period 2015–2024. Motivated by recent increases in bank profitability, the study addresses what factors explain Swedish banks’ net interest margins and if it’s mainly driven by the changes in the policy rate. Drawing on the dealership model by Ho and Saunders (1981) we develop an empirical panel

This thesis investigates the implementation of China’s Solar Energy for Poverty Alleviation Programme (SEPAP), a state-led initiative introduced in 2014 to address rural poverty while supporting the expansion of the domestic photovoltaic (PV) industry. Rather than evaluating outcomes, the study explores how SEPAP was translated from central policy into local practice across two counties in Jiangsu

Denna uppsats analyserar det svenska anställningsskyddet ur ett historiskt perspektiv från 1833 års legostadga till dagens arbetsrättslagstiftning (Prop. 2021/22:176). Uppsatsens huvudfokus ligger på kraven för att en uppsägning ska vara giltig (7 § LAS) och turordningsbestämmelser vid arbetsbrist (22 § LAS). Anställningsskyddet har genom historien gått i vågor mellan starkt skydd och svagt skyd

The Swedish Museum field has seen an emergence of new private actors who use the term museum, but whose operations often differ from the general museum sector, especially by moving away from collecting practices in favor of experiencebased concepts. This development could challenge the traditional view of museums, which have historically been defined in terms of collecting, conservation, research
