Atmospheric particles play a significant role in radiative forcing through light scattering and new methods are called for to better characterize their impact. Typical Lidar systems emit single wavelength light, not utilizing full spectral information from scattering measurements. This thesis aims to use a hyperspectral lidar system to measure the spectral dependence of scattering and absorption
Needle traits are key indicators of plant physiological status and play an important role in ecosystem modelling and carbon flux estimations. This study investigates how specific leaf area (SLA), needle length and the carbon to nitrogen ratio (C:N) vary across canopy height (vertical gradient) and needle age (temporal gradient) in Norway spruce (Picea abies). The study was conducted on two contras
Studien undersöker hur vi kan förstå AI för emotionellt- eller mentalt stöd, genom användares egna berättelser och diskussioner om denna typ av AI-användning. Syftet med undersökningen är att bidra till fördjupad sociologisk kunskap om hur användare upplever och tolkar stödet för att det ska bli meningsfullt och användbart för emotionellt- eller mentalt välbefinnande. Ämnet är fortfarande relativt
Despite the growing importance of Life Cycle Assessment (LCA) as a key tool to assess the environmental impact of products and services, many companies struggle with its implementation, lacking internal structures and capabilities to incorporate it into their operations. This thesis aims to understand the factors influencing companies' implementation of LCA, examining both drivers and barriers
The Sudanese revolution of 2019 was shaped in large part by the contributions of youth to collective action. Many of these youth have since been displaced by the ongoing Sudanese war. This study aims to explore how these youths’ emotion orientations towards political engagement have been affected by experiences of war and displacement. This will be explored by comparing how these youth convey thei
The Arctic is warming rapidly leading to the development of new thermokarst landscape features. Among the most rapidly developing landforms are retrogressive thaw slumps. The largest known thaw slump is the Batagay megaslump located in the Sakha republic, Russia. This thesis aims to assess the thaw slumps growth’ and yearly retreat rates through systematic digitization of openly accessible satelli
Against the backdrop of rising technological nationalism, geopolitical censorship, and cross-cultural trust pressures, Chinese technology brands face new legitimacy challenges in their overseas communication. For Huawei, directly emphasizing technological capabilities and product performance may not effectively build trust and could instead trigger defensive interpretations within a politicized co
Microplastics are becoming an increasingly bigger problem, and there are currently around 150 million tons of plastic in the ocean. Most plastic in the ocean was released on land and then transported to the ocean. There are, however, microplastics released directly into the ocean, for example from boat paint. This study will investigate paint microplastic released from the storage area in a Swedis
Detta arbete undersökte vilken av Honesty-Humility och machiavellianism som var den starkaste förklaringsmodellen för emotionell manipulation i sociala interaktioner. Metoden var en kvantitativ tvärsnittsstudie med 163 deltagare som besvarade en enkät som bestod av tre självskattningstester: HEXACO med 60 items, MACH-IV och Emotional Manipulation Scale. Resultaten visade att båda förklaringsmodellThis study aimed to explore which model between Honesty-Humility and machiavellianism that best could explain emotional manipulation in social interactions. The method was a quantitative cross-sectional study with 163 participants who answered a survey that consisted of three self-report tests: HEXACO with 60 items, MACH-IV and Emotional Manipulation Scale (EMS). The result showed that both models
As Indonesia approaches its centenary, the transition toward the "Golden Indonesia 2045" vision is increasingly challenged by a rising "Demographic Tax,” the economic burden associated with an aging population and an increasing dependency ratio. This research investigates the feasibility of attaining high-income status by evaluating the compensatory roles of productive aging alongsi
High-energy proton-proton collisions such as the ones happening at the LHC can result in the formation of the QGP, a state of matter similar to the early Universe's. One property of the QGP is strangeness enhancement, leading to the formation of strange flavoured particles such as $\Xi$, $\Lambda$ or $K$. The aim of this thesis is to study the production mechanism of a strangeness-balanced tri
This thesis initially highlights the broader context of tech elites and far-right movements emerging within outer space as political space. The issue that this thesis addresses is how tech elites’ imaginaries tied to outer space not only extend Earth politics but also could challenge society on Earth. The aims are to critically examine how tech elites over time construct the need for outer space t
Astrophysicists have long studied the early Universe in an attempt to explain where galaxies, and by proxy us, come from. In this thesis, the global properties of galaxies at z = 3, where star formation plays a large part , are studied when changing the stellar feedback strength and resolution in simulations. The simulation code used is based on RAMSES, using a similar setup to VINTERGATAN. Four s
This study investigates the technical and organizational challenges Swedish small and medium-sized enterprises (SMEs) encounter when generating and managing environmental data through information systems for sustainability reporting under increasing ESG and CSRD-related value-chain demands. The study focuses on SMEs that are not directly subject to mandatory CSRD reporting but are affected through
The issue of cultural appropriation is a prevalent matter in fashion, as well as a matter of cultural preservation. The Spring Summer 2025 collection by Prada showcased several pairs of ‘flat leather sandals’ very closely resembling traditional Indian footwear, Kolhapuri chappals. The following paper addresses this issue through a sociological lens, applying decolonial understandings of power rela
This thesis investigates the extent to which and how non-hegemonic identities are discursively constructed in terms of race and gender in postcolonial contexts, as well as the implications thereof for hegemonic state ideology. KNEECAP, a music group from Northern Ireland, has been the subject of media controversy over the past two years for protesting the ongoing genocide in Gaza during its live p
This study investigates transactional friction in Instagram’s informal social commerce environment defined as the cumulative operational, cognitive, and trust-related effort that small-scale sellers and their buyers must expend to complete a commercial transaction through direct messaging in the absence of integrated platform support. Instagram is highly effective at generating purchase intent
We first motivate fusion systems and provide basic definitions. Then we discuss saturated fusion systems and the equivalence of various definitions found in the literature. We then give the definitions of group (co)homology and introduce (co)induced modules, restriction, conjugation and transfer homomorphisms, Shapiro’s lemma, and prove the Cartan-Eilenberg stable elements theorem. Thereafter, we
Teacher shortages and occupational strain have increased interest in understanding the factors that support long-term teacher sustainability. Drawing on the Job Demands-Resources (JD-R) model and the Sustainable Working Life for All Ages (SwAge) framework, this study examined how organizational demands and resources relate to teacher professional sustainability in Hungary and Sweden. Professional
Atrial fibrillation is characterized by rapid and irregular atrial activity, where the atrioventricular (AV) node regulates how many impulses are conducted to the ventricles. Rate-control treatment aims to reduce the ventricular rate, but patients may respond differently to treatment. In this thesis, a model-based framework was applied to ECG-derived RR interval data from the RATAF II study to est
