: The COVID-19 pandemic has the potential to worsen mental health problems in the general population, including increasing engagement in addictive behaviors. Here, we describe observations suggesting that the current crisis and its sequelae may worsen problem gambling. The current pandemic may impact financial and psychological well-being due to social isolation during spatial distancing, and thes
Material science has become an important research area in order to fulfill today’s requirements on lighter, cheaper and more sustainable materials. The European spallation source is a research center based on the world’s most powerful neutron source, which will enable new possibilities to evaluate material properties down to an atomic level. The linear accelerator (Linac), accelerates with help of
Purpose and research question: The purpose of the study is to examine the effect ESG disclosure exerts on a firm’s propensity towards public or private debt. Methodology: For the panel data, pooled OLS and fixed effects models are applied. A quadratic term is introduced to test for non-linearity between bond debt ratios and ESG disclosure scores. An instrumental variable approach and a sharp regre
Experiments at particle colliders provide experimental verifications of theories in particle physics, and allow to search for new particles. Computer programs are used to simulate particle collisions. Those so-called event generators can be used to prove theories and compare their results to actual collisions from the colliders. Even though those programs run on powerful computer systems, the even
There is a growing interest in integrating indoor and outdoor spaces and our experiences on both sides. Nevertheless, despite being a constant topic in architectural research, there is little academic work that shows the role of furniture as great tools for creating that connection. This degree project aims to show the enormous potential of furniture to be a useful tool to connect indoor and outd
Phosphate is fundamental for optimal growth and reproduction for plants. However, due to low solubility, not all phosphorus in the soil is available to the plant. It has recently been discovered that plants can take up complex phosphate-containing organic compounds, such as phospholipids. This depends on membrane transporters, more specifically lipid flippases. In the model plant Arabidopsis, the
Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling. Therefore,
Since the purchasing expenditure of many companies is such a large part of the total cost and 99,8 % of companies are classified as Small and Medium Sized Enterprises (SME), one might expect that theories on purchasing strategy would not only be conducted for large companies but also SMEs. In order to fill this gap in theory, this thesis aims to create a purchasing strategy framework for SMEs in t
Title: System Dynamics Perspective on the Business Model for Sustainability: A Multiple Case Study in the Architecture Industry Purpose: The primary purpose of the study is to explain how the system dynamics between the Value Configuration, Partner Network, and Capabilities work in a Business Model for Sustainability of small and large architecture firms. Methodology: We followed an abductive, q
There are plenty of IT-consultancy firms operating today, and the numbers show that they keep getting more and more. At the same time, the demand for these services are increasing. The biggest issue that these firms face today is related to finding new business opportunities. The complexity surrounding the purchase of these services make it a complex subject that is hard to fully grasp. It include
Long working hours and burnout as well as other stress-related symptoms are common concerns amongst knowledge workers. An obvious solution might be to reduce working hours, for example, to a 30-hour workweek. Hence, this explorative study is interested in exploring the effects of the 30-hour workweek on knowledge workers. Object of study is a digital marketing agency; eleven semi-structured interv
This paper investigates the characteristics and history of value added taxes. Many previous studies have focused on the theoretical implications of value added taxes; this paper differs in the method used as well as the phrasing of research question. This paper seeks out to answer whether a redesign of the current Value Added Tax system in Sweden could be a Pareto improvement. It looks at relevant
Purpose: The purpose of this thesis is to investigate whether the length of the maturity profile of a firm’s debt has any implications for the capital structure. Theoretical perspectives: A deductive approach, using econometric methodology to examine the correlation ( if any) between the selected variables, and the significance (if any) of that correlation. The output of our econometric model is f
The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation
The paper researches the viable options for Hamas as a case study in the development of a peace paradigm through answering the question of ‘What should Hamas do, while under siege, to act responsibly in favor of the interests of its constituency?’ By comparing the logics of social constructivist and realist theories as methods of analysis in addressing the formulation, operationalization and socia
The chirality-flow formalism provides a simple but efficient way to rewrite and evaluate Feynman diagrams and has recently been shown to also optimize automated numerical scattering matrix element evaluations in massless tree-level QED. In this thesis we extend the numerical QED model to massless tree-level QCD in the MadGraph5_aMC@NLO framework. It is shown that a good gauge choice for external g
Green ammonia, produced from renewable hydrogen, is emerging as an important energy carrier and decarbonized fertilizer alternative. However, its production is highly energy-intensive, making process efficiency critical to its commercial viability. This study investigates how targeted heat integration can enhance the energy and cost efficiency of green ammonia production based on a 200 MW PEM elec
The observed imbalance of matter and antimatter in the universe cannot be fully explained by the Standard Model of particle physics. One proposed mechanism to account for this discrepancy is the violation of baryon number B, a process that has yet to be experimentally observed. The HIBEAM/NNBAR project, a proposed two-stage experiment at the European Spallation Source, aims to find evidence of bar
Chronic respiratory diseases, such as asthma, represent a significant global health issue. Symptoms are commonly treated through inhalation therapy, enabling the delivery of the active pharmaceutical ingredient (API) directly to the lungs. Pulmonary drug delivery offers several advantages, including reduced risk of systemic side effects and a minimally invasive route of administration. Dry-powder
