Okun’s Law is a negative relationship between GDP growth and changes in unemployment. The aim of this paper is to investigate whether there is age heterogeneity in Okun’s Law across the OECD during the period 2000-2024. The study is based on panel data for the 38 OECD countries during the period in question. The analysis focuses on whether the Okun coefficient and the effect of changes in GDP on u
This thesis investigates how venture capital (VC) firms allocate funding and evaluate investment opportunities based on firms’ ex ante characteristics, with a particular focus on scale-up strategies and network externalities. Using a dataset of 4,476 VC-backed firms from the transactions of the 25 largest U.S. venture capital firms between 1970 and 2026, the study introduces a novel text-based app
Rotating detonation combustion (RDC) is a promising pressure-gain combustion technology with the potential to improve the thermodynamic efficiency of future propulsion and power-generation systems. In RDC systems, efficient mixing between fuel and oxidizer prior to the arrival of the detonation wave is essential for stable operation and overall combustor performance. The present work investigates
Cooperation between unrelated males and females can be read through three lenses that make different predictions about who should be rewarded: biological markets, audience-directed signalling, and reciprocity rules that require no bookkeeping. Trying to separate these frameworks observationally is a challenge because control of a resource normally travels with dominance. Across 30 provisioning eve
This thesis focuses on the change in legislation SFS 2025:974 regarding the Planning and Building Act (2010:900). The change in legislation came into effect on the first of December 2025. The new legislative change entails that deviations from attic conversion bans in detailed development plans are permitted, but only if the implementation period is over. The legislative change also applies to are
It is often suggested that seasonal environments impose changing ecological conditions that can influence mammals’ activity periods and foraging peaks. However, despite strong seasonal changes in food availability and ecological conditions, the common shrew (Sorex araneus) must forage continuously throughout the year. This raises the question of whether its foraging strategy remains consistent acr
Anthropogenic underwater noise is an important source of disturbance for cetaceans, which use sound for a variety of vital functions. In Northern European Waters the offshore wind industry occupies several relevant areas where marine mammals forage, mate or migrate. The impact of offshore wind farms is therefore of particular concern for species such as harbour porpoises, who are present throughou
Increasing anthropogenic emissions of polycyclic aromatic hydrocarbons (PAHs) have contributed to a global contamination of freshwater ecosystems. PAH’s high lipophilicity and genotoxicity represent a threat to local mussel populations, which have limited means to metabolise them. Swan mussels (Anodonta cygnea), which are near-threatened in Europe and sensitive to PAH pollution, were chosen to inv
This thesis develops a Deep Operator Network (DeepONet) surrogate for rapid reconstruction of three-dimensional aerodynamic flow fields around parametrically varied Ahmed-body geometries. Starting from the baseline 25◦ Ahmed-body geometry, 200 distinct vehicle geometries are generated by varying three geometric parameters: the rear-slant angle, rear-slant length and front-body radius. Steady, inco
In a time of ecological crisis, the notion of the commons can become a means to promote social justice, equity and sustainability responses to the challenges of a changing landscape. This chapter aims to reflect on the urgent need to rethink and practice the commons by understanding the ontological, epistemic and planetary backdrop within which this concept is embedded. Before considering the ethi
As a catalyst for continued research on ethics and the commons, this chapter reflects on current ethical issues, key questions, and directions forward. We begin by arguing for the need to build ethical awareness, and then outline some of the ethical claims linked to the commons and the potential claims of different ethical theories about the commons. We believe there is a plurality of ethical pers
Läsning är ett centralt inslag i högre studier, och svårigheter att läsa tryckta texter kan innebära ett stort hinder för att genomföra en akademisk utbildning. Studenter som på grund av en funktionsnedsättning har svårt att läsa tryckta texter har rätt att få tillgång till sin kurslitteratur i form av tillgänglighetsanpassade ljudböcker, så kallade talböcker, producerade av Myndigheten för tillgä
Historical linguistics aims to investigate the innovation stage of a grammatical variant as well as the later community-wide propagation in order to fully understand the change (Fischer 2004). This paper focuses on individual contact-based grammatical innovations in a community setting, viewing the speaker as the “locus of change” (Weinreich 1953/1968: 1; Romaine 2005; Wei 2013). This provides a w
This article proposes to identify possible instances of grammatical borrowing in the speech of the bilingual community of native English speakers in Prague. The linguistic phenomena identified in the research are analyzed to determine whether they can be attributed to grammatical borrowing from Czech to English caused by contact between the two languages, or whether they are the result of linguist
This paper is a parallel study to “Czeching Out a Language Contact Situation: Grammatical Replication and Shift in South Australian Czech” (Castle forthcoming) and investigates the reasons why grammatical borrowing and attrition processes occur within the South Australian Czech community. In-depth qualitative interviews were conducted with six participants, yielding results including reports of co
This paper identifies causes of grammatical borrowing and related grammatical phenomena in L1 English L2 Czech immigrant speech. This study contributes to the literature on causes of grammatical borrowing and considers key ideas including social pressure (Thomason and Kaufman 1988), cognitive pressure (Matras 1998; Sanchez 2005) and gap filling (Campbell 1993). Thirteen semistructured interviews w
Technological advances in the AI industry suggest that the world as we know it is coming to an end. Something worse may be emerging, but so is something else. The future may seem pre-programmed, but it is open and should be discussed from ethical and philosophical perspectives. How can we shape a democratic society that integrates artificial, human, and non-human life in a way that avoids repeatin
