Gamma-ray bursts (GRBs) are intense, short-lived bursts of gamma-ray radiation observed up to a high redshift (z ∼ 10) due to their luminosities. Thus, they can serve as cosmological tools to probe the early Universe. However, we need a large sample of high-z GRBs, currently limited due to the difficulty in securing time at the large aperture telescopes. Thus, it is painstaking to determine quickl

The emission spectra from the ablation of airborne alumina nanoparticles by a 532 nm nanosecond pulsed laser are investigated to clarify the underlying mechanism and the applicability of different laser diagnostic techniques such as the laser-induced incandescence (LII) and the laser-induced breakdown spectroscopy (LIBS). The particles were observed to be completely ablated above the laser fluence

The current classification of diabetes had its genesis over 85 years ago, when individuals with diabetes were first subclassified into insulin sensitive and insulin insensitive states based on the response to an oral glucose tolerance test. About 35 years later, the contemporary classifications of type 1 and type 2 diabetes were coined. Today's evidence, however, suggests that multiple etiologic a

Short afterword to a collection with Swedish translations of poems by Colombian poet Ángela García

The launch of the DeepSeek R1 chatbot in early 2025 prompted a flurry of responses. In Asia, it touched off discussions about gaining ground against big tech and national AI strategies. The reactions offer a window onto thinking in the region about technology policy, US-China rivalry, and international cooperation.

During the Last Glacial Period (LGP), Greenland experienced approximately 30 abrupt warming phases, known as Dansgaard-Oeschger (D-O) events, followed by cooling back to baseline glacial conditions. Studies of mean climate change across warming transitions reveal indistinguishable phase offsets between shifts in temperature, dust, sea salt, accumulation, and moisture source, thus preventing a comp

Aquaglyceroporins are channels that facilitate the flux of glycerol and water across lipid bilayers. Although structural information is available for several aquaglyceroporins, the details of how water and glycerol selectivity are maintained and how protons are excluded remain elusive. An approach to obtaining data on the hydrogen atom positions is to apply neutron macromolecular crystallography.

This thesis examines how entrepreneurs organise flexible working practices in self-structured environments and how these shape their perceived work-life balance. Unlike research focused on employees in traditional settings, this study explores entrepreneurs operating with high autonomy and little external structure. Drawing on Self-Determination Theory, Boundary Theory, and Spillover Theory, it in

While fintech is often promoted as a disruptive and inclusive sector, evidence shows gender disparities from within its ecosystem involving leadership, the foundation of teams, venture creation, and investment networks. Our study draws on social capital and role congruity theories to investigate how gendered exclusions are produced and sustained through social dynamics in the fintech entrepreneuri

This thesis explores how early-stage startup founders use their professional networks to acquire equity investment from venture capitalists and business angels. Through qualitative interviews with founders across various industries, the research reveals essential networking practices that lead to successful fundraising efforts. The study highlights how building trust and credibility with network c

Entrepreneurs often face the need to make quick decisions under uncertainty. To cope with this pressure, they may develop cognitive biases such as the illusion of control, where they overestimate their influence over outcomes, and the belief in the law of small numbers, where they rely on limited information to draw conclusions. While these biases are highly relevant in entrepreneurship, there is

As geopolitical instability and war increasingly affect entrepreneurial ecosystems, there remains a critical gap in understanding how ventures sustain operations under conditions of active, prolonged conflict. While existing resilience literature often focuses on temporary crises or post-conflict recovery, this study explores how tech small and medium-sized enterprises (SMEs) in Ukraine build oper

This study explores how short-term innovation training, particularly in design thinking (DT), influences intrapreneurial competencies among public sector employees. Focusing on a case study within Stockholm Stad’s Department of Elderly Care, the research compares employees who participated in a structured DT workshop with those who did not. Using a qualitative, comparative case study design and th

The gig economy has expanded rapidly across the globe, and has become an increasingly influential feature of modern labour markets. The flexibility and autonomy offered by gig work coupled with the ability to earn a steady income are recognised benefits by many workers on digital platforms. These benefits can work synergistically with entrepreneurship, which is often characterised by uncertain tim

This study explores how airports develop and repeat specific behaviors that help them remain innovative over time. As digital needs increase, climate regulations tighten, and passengers demand better experiences, airports must remain dependable while also finding ways to adapt. This study examines the behaviors and habits that make innovation a part of everyday work. To further understand this, tw

The goal of this research is to investigate how the use of provocative place branding, by companies, influences audience engagement with national identity, from a sensemaking perspective. The study specifically investigates how audiences, in the case of residents of Denmark, make sense of provocative content and how it influences their sense of place and national identity. The answered research qu

In today’s world, many companies are pushed to adapt their business models in response to evolving external pressures. While business model change has received increasing attention in research, relatively little is known about how such change actually unfolds inside organizations. Responding to calls for a more dynamic view of business models, this thesis explores how strategy process factors medi
