This thesis explores how immersive virtual reality can be designed to support emotional engagement, relaxation, and a sense of connection to nature. Based on experience design and gesture interaction theory, this project developed a VR experience titled "Night Journey". In this experience, users can explore a virtual nature and interact with a responsive ecosystem through natural body ge
This study examines how transportation justice is expressed and materialized in the urban district of Brunnshög in Lund, Sweden. The study is situated within contemporary debates on sustainable mobility, reduced car dependency, and socially just urban planning. Its aim is to analyze Brunnshög’s transportation system from a justice perspective in order to examine both how justice ideals are express
The current crime debate in Sweden surrounds the overarching issue of criminal networks and children’s exploitation by them. In Sweden, younger children are getting involved in serious criminality, carrying out offences for criminal gangs such as murder and aggravated weapons crimes, which has sparked the government’s interest in possible changes to the youth criminal justice system. One of those
This study investigates how varying hyperparameters of the Synthetic Minority Over-sampling Technique (SMOTE) affects the stability of model explanations produced by SHapley Additive exPlanations (SHAP) and Local Interpretable Modelagnostic Explanations (LIME). By using an eXtreme Gradient Boosting (XGBoost) classifier trained on 11 medical datasets with varying imbalance ratios, four SMOTE parame
Introduction: Liquid-liquid phase separation (LLPS) is a process that occurs often in biological environments, and elastin is a protein that utilizes it to form elastic fibres. Understanding elastin’s LLPS is very helpful for creating new biomaterials and researching diseases, where LLPS occurs. Background: The coacervation of elastin is widely researched, but the combination effects of salt, hea
In 2025, the unauthorized release of four lynx in Scotland sparked widespread media speculation about “guerrilla” rewilding. Drawing on political ecology and environmental justice, this thesis applies a critical discourse analysis to investigate how media outlets framed lynx reintroduction following the unauthorized release. The findings show that media coverage constructs rewilding as contentious
This study examines how tourism affects and reshapes residents’ identities and sense of place in the Sanno-chiku of Takayama City in Gifu Prefecture, Japan. This study focuses on residents’ lived experiences and discusses tourism through the ideas and concepts of place, sense of place, identity, mobility, and commodification. This study asks two research questions: 1) How does tourism shape local
Polyhydroxyalkanoate (PHA) synthases (PhaC) are the pivotal biocatalysts governing the biosynthesis of biodegradable polyesters. Current research on their structure and mechanisms remains limited, and the chemical mechanisms of all PHA synthases are still under debate. Despite some speculation, further physicochemical studies are needed to understand their structure and function. The primary obje
Purpose: To examine whether generative AI adoption influences analyst forecast error and bias, and whether the relationship differs across firms with different characteristics. Methodology: The study applies a quantitative panel-data approach using pooled OLS and firm fixed effects regressions. Interaction models are used to examine whether firm size, segment complexity, intangible intensity an
The ongoing urban transformation in Kiruna is one of the most extensive relocation projects in modern history. While the type of great challenges, filled with uncertainties both for planners and the local community exist within most urban planning situations, the Kiruna example provides an extreme, and a particularly obvious case that makes it interesting to illustrate the reinvention of a town ca
This master’s thesis explores the ethnic self-identification of young Russian speakers from Estonia, as well as their sense of belonging to Estonia and the Estonian society. The research focuses on an understudied group of younger people who did not experience the life under the Soviet Union, which leads to them not sharing the identification of a “Soviet citizen” that was common for the older gen
Ring voltage-controlled oscillators (Ring VCOs) are widely used in clock generation because of their compact area and wide tuning range, but their high inherent phase noise limits their application in high-performance systems. To address this, this thesis presents a low-power dual-path sub-sampling PLL (SSPLL) covering a wide frequency range from 2GHz to 4GHz. To effectively suppress the phase noi
Disasters are social and political constructs, and their impacts are shaped by people’s action and inaction. How we allocate time, money, and resources matters in shaping the outcomes post-disaster, especially of those most vulnerable. While the lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community is an understudied demographic in disaster research, existing studies show that LGBTQ+ p
The increasing use of artificial intelligence (AI) is often portrayed as central to efficiency and innovation in the public sector. However, previous research shows that many AI initiatives struggle to be integrated into everyday work practices. Against this background, this study aims to develop an in-depth understanding of how change management shapes the use of AI in public organizations. The s
Att leva med klusterhuvudvärk innebär att hantera återkommande smärtanfall och samtidigt leva med osäkerheten kring när nästa anfall kan inträffa. Denna uppsats analyserar klusterhuvudvärk som ett temporalt livsvillkor snarare än enbart som ett neurologiskt smärttillstånd. Med utgångspunkt i tio kvalitativa intervjuer med personer som har diagnostiserad klusterhuvudvärk undersöks hur återkommande
Inflight safety briefing videos are shown on flights to communicate crucial safety information. However, passengers often ignore these videos as they are perceived as repetitive and unengaging. This study explores whether passenger engagement can be increased through the use of gamification. An iterative user-centered approach was adopted to evaluate both traditional safety briefing videos and a g
Syftet med studien var att undersöka universitetsstudenters användning av musik för emotionsreglering i vardagen, med särskilt fokus på att använda musik för att påverka hur en situation upplevs respektive att använda musik för att rikta uppmärksamheten bort från obehagliga tankar eller känslor. Studien genomfördes som en kvantitativ tvärsnittsstudie via webbenkät. Det slutliga urvalet bestod av NThe aim of the study was to examine university students’ use of music for emotion regulation in everyday life, with a particular focus on using music to alter situational experiences and using music to redirect attention away from distressing thoughts or emotions. The study employed a quantitative cross-sectional design, with data collected through an online survey. The final sample consisted of N
With four years left to fulfill the goals of the UN’s Ocean Decade, it has become increasingly important to find solutions for the threats our oceans are currently facing. French Polynesia has the largest marine protected area in the world and relies heavily on tourism for development. Through semi-structured interviews with stakeholders in the tourism industry in Tahiti, I study their role in mar
Materialvariation i gråjärn diskuteras vanligtvis utifrån metallurgi eller bearbetbarhet, medan dess konsekvenser för produktionsflödet och styckkostnaden är mindre systematiskt karaktäriserade. Detta examensarbete undersöker hur sammansättningsvariation i gråjärn propagerar genom bearbetningsrespons till produktionssystemets beteende, och kvantifierar de resulterande ekonomiska konsekvenserna perMaterial variability in grey cast iron is usually discussed in terms of metallurgy or machinability, while its consequences for production-flow behaviour and per-part economics are less systematically characterised. This thesis investigates how compositional variability in grey cast iron propagates through machining response into production-system behaviour, and quantifies the resulting per-part e
