This study examines whether machine learning (ML) models can forecast daily Bitcoin price directions and generate statistically significant alpha in trading strategies. Employing a dual-model approach, we utilize a Random Forest (RF) classifier, leveraging its non-linear strengths and a LASSO-penalized logistic regression as a linear benchmark. Both models are trained on a comprehensive dataset o
This thesis examines the conditions under which the triangular simplification mechanism under Article 141 of the VAT Directive may apply to quadrangular chain transactions involving four taxable persons established or identified for VAT purposes across multiple Member States. The triangular simplification mechanism relieves the intermediary operator in a three-party chain transaction from register
This thesis investigates how human rights responsibility is constructed and negotiated between the Zambian state and foreign mining companies in Zambia’s mining sector under conditions of economic dependence on foreign investment. The study is motivated by observations from an internship in Zambia, where mining was consistently framed as central to development while questions of responsibility rem
The geopolitical competition between the United States and China over artificial intelligence has emerged as one of the defining dynamics of the 21st century. Yet despite a growing body of work on AI innovation, a structured and recent sectoral comparison of the conditions organizing AI development in each country remains underexplored. This thesis addresses that gap by applying Malerba's (200
In light of the current climate- and biodiversity crises, the political interest in peatlands has increased dramatically as these ecosystems hold the potential to address several urgent societal challenges. In Denmark, a political agreement from 2024 aims to restore 140.000 hectares of agricultural peatlands by 2030. The main goal is to reduce GHG emissions from agriculture and decrease nitrogen r
Purpose: To examine whether an acquirer’s risk exposure affects the acquisition premium paid in public-to-public M&A transactions, specifically isolating the effects of leverage and stock return volatility alongside the moderating role of free cash flow. Methodology: The study employs multivariate OLS regressions with year and industry fixed effects and heteroskedasticity-robust standard erro
Plastic pollution has rapidly escalated into a global environmental challenge. This study aims to map the intellectual structure of highly influential plastic pollution research and examine the integration of social dimensions research into its networks. We use a systematic bibliometric analysis of high-impact plastic pollution research to map the field’s intellectual structure. From an initial co
As the global economy fragments and geopolitical disruptions become increasingly frequent, understanding how firms strategically respond and adapt to these disruptions becomes critical. This thesis examines how A.P. Møller – Mærsk A/S has responded to geopolitical risk over time, and how these responses are indicative of organizational learning and adaptive capability development. Through a longit
The reserves, production from mines, supply of aluminium to society and mass fluxes of aluminium in society was assessed using an integrated systems dynamics model (ALUMINIUM) in order to reconstruct the past and investigate potential future scenarios. The investigations for input data show that the mine- able aluminium reserves are large, but finite. We get an average value for the ultimately rec
The effects of the polyamines putrescine, spermidine and spermine on the mechanical activity in smooth muscle from guinea-pig taenia coli were investigated. Tissue concentrations of spermidine and spermine were about 240 and 160 nmol g-1, respectively, while the putrescine concentration was much lower (4 nmol g-1). Intracellular [Ca2+] was determined using the Fura-2 method and the effects of extr
Nutrient availability is of major importance for plant productivity. When estimating long-term sustainability from a nutrient perspective it is therefore interesting to focus on long-term changes in the soil nutrient pools when comparing different forest types. Here, we have highlighted some factors of importance for long term nutrient sustainability (e.g., several forest rotations) and pointed ou
Background and purpose — Surveillance of scoliosis in individuals with cerebral palsy (CP) is important for ensuring timely diagnosis and identification of curve progression. We analyzed the incidence of scoliosis in relation to age, sex, and gross motor function in a population-based cohort of individuals with CP. Patients and methods — This was a prospective register study of all 1,025 individua
