This thesis explores the use of birding citizen science data and statistical modelling methods to support the construction of indicators for human-nature relationships. Motivated by the broader aspirational framework of the Nature Relationship Index, the study investigates how voluntary bird observation records can be processed into spatial and temporal measures suitable for statistical analysis,
Tillämpningar är en del av alla matematikkurser i gymnasieskolan. Matematik kan tillämpas på många olika ämnen, däribland fysik. Frågorna som undersöktes i denna studie var hur tillämpningarna av matematik på fysik används i matematikundervisning i gymnasieskolan och lärarnas inställning till användandet av fysik i matematikundervisning. Detta gjordes via semistrukturerade intervjuer. Fem verksamm
This study explores how female managers in Icelandic technology companies describe their career journeys and the turning points that shaped their progression into senior management. Eight semi-structured interviews were conducted and analysed using the Gioia methodology. The findings show that none of these women planned their way into leadership. Instead their careers were shaped by unexpected op
Forensic pathology is a branch of medicine that aims to determine the manner and cause of unnatural, suspicious or unexpected deaths that require a legal investigation. An important part of determining the cause of death is the examination of the body through an autopsy. The purpose of this project is to evaluate whether machine learning algorithms can predict cause of death based on autopsy data.
Accurate estimations of regional CO2 fluxes are essential for understanding the global carbon cycle and further mitigating climate change. Satellite-based retrievals of column-averaged carbon dioxide (CO2) from the Orbiting Carbon Observatory 2 (OCO-2) offer a promising avenue for estimating carbon fluxes with atmospheric inversion systems, as they provide higher spatial resolution and observation
Toxic workplaces have received increased attention in line with an increased focus on employee well-being and the psychosocial work environment. The complexity of the phenomenon, in combination with its negative impact on both individuals and organizations, makes it an important subject to investigate. Recent research shows that a toxic work environment is the strongest predictor of employee turno
Since the digital art commission market is a new business model in the art industry, the discovery of potential mechanisms for setting digital art commission prices is considered limited. This research explores the mechanism between an artist’s reputation level by the number of followers and artwork prices in the online digital art commission market for an exploratory study of developing the prici
Drawing on Upper Echelons Theory and Institutional Theory, this study explores the relationship between CEO narcissism, expressed through public facing digital communications, and firm- level Environmental, Social and Governance (ESG) performance across distinct institutional contexts. While emerging literature connects executive use of social media to Corporate Social Responsibility, it remains u
The global fashion industry generates approximately 2.1 billion tonnes of greenhouse gas emissions annually, yet the circular business models and sustainability initiatives promoted as its primary environmental remedy have not translated into reductions in absolute production volumes or total consumption. This study investigates why through the lens of what we term the Circular Growth Paradox: the
This study explores how organizational culture, organizational learning, and leadership enable neuroinclusive practices in large Swedish high-technical multinational organizations. Despite growing interest in neurodiversity in recent years, limited research has examined how neuroinclusive practices develop and become integrated within organizations. The study draws on theories of organizational cu
The loss of regulatory control over radioactive material and sources poses great risks to public safety. Such a situation necessitates the development of protocols and methods for effective and accurate localisation, characterisation and securement of the materials. Mobile gamma spectrometry, particularly using vehicle-borne detectors, has emerged as a viable method for in-situ characterisation of
Skin cancer is one of the most common forms of cancer worldwide and its prevalence is increasing. Current assessment of tumor extent relies mainly on histopathology after excision, and repeated surgeries are often required to achieve complete tumor removal. This leads to high medical costs and unnecessary patient discomfort. To reduce the pressure on the healthcare system, there is a strong need f
Recent work by Ghose and Pinotsis (2025) reformulated the classical FitzHugh–Nagumo neuronal model as a Schrödinger-like equation. The aim of this thesis is to investigate whether the proposed equation is able to reproduce the dynamics of the original model. Results presented here show that the reformulation is capable of capturing the conservative component of the neuronal model, but not its full
Parvalbumin (PV) interneurons are specialised inhibitory neurons that help regulate the timing and balance of neural circuits. Generating PV-like interneurons through direct glia-to-neuron reprogramming is therefore relevant for disease modelling and future regenerative strategies, but efficient acquisition of a specific PV-associated fate remains challenging. This thesis builds on a human glia-to
Numerical Weather Prediction (NWP) relies on the accurate and efficient numerical solution of nonlinear conservation laws governing atmospheric flows. However, high order DG methods are known to exhibit instabilities when applied to nonlinear conservation laws. Entropy stable methods improve the robustness of these schemes by imposing an entropy inequality on the solution and ensuring that the res
In this thesis, we study groups of superpolynomial growth, with a particular focus on the first Grigorchuk group. Introduced by Rostislav Grigorchuk in 1980, this group serves as a fundamental example of a finitely generated group of intermediate growth. The main result concerns the superpolynomial growth of the first Grigorchuk group, illustrating its relevance for the conjugacy search problem a
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
The extent of data usage today makes the problem of its smoothing and filtering more relevant than ever. In this thesis, we explore one of the possible approaches to this problem: smoothing splines. When trying to clean noisy data, we want the final result to be both smooth and close to the original data set, thus it is logical to simultaneously minimize both of these values, while controlling the
In this thesis, the possibility of cooling small electronic products using new methods is investigated. By improving a base product, different types of methods for enhanced heat dissipation are evaluated. Initially, a literature study is conducted with the goal of analyzing the market and exploring new technology. The literature study is integrated with interviews to gain a more informed understa
