Head-mounted mixed reality devices are making their way into airline pilot training. Devices that use passthrough video hold much promise but come with caveats. Because current generation passthrough video devices occlude natural light, users rely entirely on a digital video feed that lacks the visual fidelity and field of view of the unaided human eye. The application of head-mounted extended rea

The exponential growth of Big Data, the Internet of Things (IoT), and Large Language Models (LLMs) has significantly increased the computational and energy demands of modern computing systems. In response, research has increasingly focused on alternative machine learning paradigms and hardware architectures that reduce model complexity and computational load. One such paradigm is the Kolmogorov-Ar

Public organisations need legitimacy to operate and there are many ways for them to gain, maintain and repair it. Without legitimacy, public organisations can face challenges such as legitimacy gaps or crises, which can have lasting effects on their function and authority. This thesis aims to shed light on how public organisations in Iceland communicate when their legitimacy is questioned and wha

Entrepreneurial decision-making is a complex and dynamic process influenced by the challenges, uncertainty, and environmental situations inherent to the entrepreneurial journey. This study investigates how entrepreneurs with relevant professional backgrounds navigate the shift between analytical, structured and intuitive, experience-driven decision-making approaches over time. The methods involved

This thesis explores how sustainable entrepreneurs adapt their motivation and identity amid the emotional, moral, and strategic tensions of building purpose driven ventures. While previous research has examined motivation and identity separately, little attention has been paid to their interdependence, particularly in high uncertainty environments where values and viability collide. Integrating Se

bstract The real estate sector in Sweden has long been characterized by high entry barriers, strict regulations, and a high demand for large initial capital. These factors make it challenging for new ventures to succeed in the market. With this background, it seems relevant to understand which driving factors can be related to entrepreneurial success. This study researches how specific characteris

This thesis explores how sustainability-oriented venture capital firms (sVCs) evaluate sustainability-oriented early-stage startups. While sustainability has gained prominence in financial discourse, its role in early-stage venture evaluation remains diffuse. Startups with strong sustainability missions often face investor hesitation; not due to lack of relevance, but due to limited standardizatio

This study explores the different psychological processes and psychological capital resources that help entrepreneurs sustain motivation to re-enter entrepreneurship after discontinuing a previous venture. While existing literature has focused intensely on the financial and social costs of business failure, minimal yet growing scholarly attention has focused on the psychological costs of failure a

Att kunna skräddarsy biologiskt nedbrytbara stärkelsepartiklar för användning i medicintekniska produkter låter kanske som science fiction, men det håller snabbt på att bli verklighet! Dessa mikroskopiska partiklar tillverkar man av något som de flesta har hemma, potatisstärkelse och kan användas i medicintekniska produkter för att exempelvis blockera blodflödet till tumörer eller upptäcka läckageDegradable starch microspheres (DSMs) are promising biomaterials with expanding medical applications due to their biocompatibility and controlled degradation. DSMs are produced by forming a water-in-oil emulsion using a starch solution, an emulsifier e.g. Starch Acetate Butyrate (SAB) and toluene, followed by crosslinking using a crosslinker, e.g. epichlorohydrin (ECH). The relationship between re

This thesis investigates how business angel investors interpret and evaluate hybrid entrepreneurial teams, startups led by founders who retain salaried employment while launching their ventures. While hybrid entrepreneurship is increasingly common, it challenges traditional heuristics around founder commitment, team scalability, and investability in early-stage finance. Drawing on ten qualitative

Rationale: Patients with obesity hypoventilation syndrome (OHS) have high risk of hospitalization, which might be decreased by home mechanical ventilation (HMV). Objectives: To evaluate annualized hospitalization rate (AHR) and changes in AHR in patients with OHS starting HMV and explore if there were any differences in AHR by starting HMV acutely or electively. Methods: This was a population-base

Background: There are currently no molecular tests to identify individual breast cancers where radiotherapy (RT) offers no benefit. Profile for the Omission of Local Adjuvant Radiotherapy (POLAR) is a 16-gene molecular signature developed to identify low-risk cancers where RT will not further reduce recurrence rates. Methods: An individual participant data meta-analysis was performed in 623 patien

Two different diets able to induce dietary hyperammonaemia (a methionine–choline-deficient (MCD) diet and a methionine-deficient diet enriched with ammonium acetate (MAD + 20% ammonium acetate)) were tested in a rat model. The diets were shown to have different modes of action, inducing significant hyperammonaemia (HA) and growth retardation in the rats, with different metabolic consequences. The

The molecular surface compositions of aerosols can differ considerably from their bulk counterparts, an aspect often overlooked in climate models. This oversight can potentially affect our understanding of the complex interplay between composition, optical characteristics, and their influence on cloud formation and properties. A substantial portion of aerosol mass often includes organic compounds,

This thesis investigates how startups in Tier 2 European cities achieve sustainable growth by engaging with their local entrepreneurial ecosystems. While prior research has largely focused on major capital cities, this study aims to understand how emerging urban canters with less mature infrastructures can still support high-growth entrepreneurial activity. A qualitative research design was employ

Access to financing for women entrepreneurs plays a fundamental role in the creation and development of their startups. Our study found that women founders, specifically within tech startups, face barriers and challenges when searching for and navigating different types of financing options. There is a gap in the literature regarding gender disparities in entrepreneurial finance and limitations of

This thesis explores how business angels’ (BA’s) human- and financial capital contribute to the early-stage development of start-ups. While previous literature has extensively discussed BAs' financial roles, the combined effect of both capital types, particularly in relation to relational trust, remains underexplored. Addressing this gap, the study applies a qualitative approach, interviewing

For decades, entrepreneurs faced the same trade-off: either pursue cost leadership and grow fast through various scaling strategies or pursue differentiation strategies by emphasizing personalization of their services to customers. Nevertheless, the situation has changed when new technologies such as artificial intelligence, rising computing power, digitization of firms, or cloud services started

Despite generative Artificial Intelligence’s (AI) explosive growth in popularity and record of biased outputs, little attention has been paid to the technology’s potential to shape perceptions around sustainability. This analysis investigates which perceptions about climate change causes, impacts and solutions are visually naturalised or marginalised by three text-to-image AI models: GPT‑4o, Ideog
