Background and AimsThe ecosystem engineers Sphagnum (peat mosses) are responsible for sequestering a large proportion of carbon in northern peatlands. Species may respond differently to hydrological changes, and water level changes may lead to vegetation shifts in peatlands, causing them to revert from sinks to sources of carbon. We aimed to compare species-specific responses to water level drawdo
Single-trait eco-evolutionary models of arms races between consumers and their resource species often show inhibition rather than promotion of community diversification. In contrast, modelling arms races involving multiple traits, we found that arms races can promote diversification when trade-off costs among traits make simultaneous investment in multiple traits either more beneficial or more cos
This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. The thesis begins with a literature rev
There is a need to identify leverage points for a broader cultural transformation that addresses the root causes of the nature-climate emergency. Music and art festivals are creative free spaces outside the everyday workings of society that have the potential to plant the seeds of a holistic, sustainable future. I combine prefiguration and the three spheres of transformation in a framework to inve
Pellets are a form of biomass used in highly efficient heating systems. Thus, development of pellet markets could improve energy efficiency, reduce emissions of greenhouse gases, create employment opportunities, increase energy security, and improve air quality. The present research explores the development of the domestic pellet market in Bulgaria. The research’s objectives are to investigate bar
Muntlig bevisning har länge medfört problem i den svenska hovrätten. När ett mål når den andra instansen har kvaliteten på muntlig bevisning blivit sämre, inte minst på grund av att minnesbilder hos förhörspersoner försvagas med tiden. Trots det har utgångspunkten, allt sedan det muntliga och omedelbara förfarandet introducerades genom 1948 års rättegångsbalk (RB), varit att principen om det bästaOral evidence has caused problems in the Swedish courts of appeals for a long time. When a case reaches the higher court, the quality of oral evidence has deteriorated, primarily because the recollections of witnesses and parties have weakened over time. The starting point has, nevertheless, been that the principle of the best evidence requires renewed questioning of witnesses and parties in the c
The Troubles in Northern Ireland have played a prominent part in modern European history. Despite the success of the Peace Process in the 1990s and subsequent stabilisation of the conflict through the introduction of power-sharing and paramilitary decommissioning of weapons, tensions still dominate the province. This thesis uses the Copenhagen School of Security Studies to investigate processes of
The rise of solo living presents significant social and environmental challenges, particularly in high-income countries like Denmark where nearly half of households are single occupancy. This study explores the social dynamics driving the trend towards living alone through in-depth interviews with 23 individuals living alone in Denmark. Pathways to solo living include urban relocation, aging out o
How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur
We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati
This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic
Far beyond its innocence, children and child welfare initiatives have emerged as powerful symbols in Indonesian political campaigns. This research focuses on Joko Widodo and Prabowo Subianto, showing how their use of initiatives like Smart Card and Free Lunch Program projected legitimacy and garnered votes during the 2014, 2019, and 2024 elections. It uses two main methods: reflexive thematic anal
This study examines how AI for minors is framed by AI companies and constructed in public discourse in China and the United States. Using Rhetorical Arena Theory and framing theory, the study analyses corporate communication from four AI platforms (ChatGPT, Gemini, Grok, and Doubao) together with public discourse materials, including mainstream media, NGO reports, and online commentary. Reflexive
Drug-resistant bacterial infections are among the most severe physiological challenges facing human health. Therefore, the detection and inactivation of pathogenic bacteria remains a crucial therapeutic goal in modern society. In this study, we design multifunctional nanocomposites aimed at bacterial binding, fluorescence labeling, and synergistic antibacterial treatment. These nanocomposites are
This study analyzes the transition to mechanized forest management and the implementation of sustainable-yields forestry in Sweden during the 1950s and 1960s. The objective is to produce insights that are relevantfor policymakers working with forests and the climate transition today. The analysis focuses on how the Swedish National Association of Forest Owners’ Associations (SSR)—an association or
Depressive and anxiety disorders are leading causes of disability globally. Therapist-guided, Internet-delivered cognitive behaviour therapy (ICBT) is an established treatment for depression and anxiety, but a considerable proportion of treated patients do not achieve sufficient improvement. Predicting symptom changes based solely on clinical variables is challenging, and genetic data could offer
