This thesis conducts an in-depth investigation of the conformal two Higgs doublet model (C2HDM) in its most general form, integrating complex couplings λ5, λ6, λ7 and a CPviolating phase e−iδ. This setup enables a detailed exploration of $\mathcal{CP}$-violation and its impact on electroweak phase transitions (EWPT) and gravitational wave (GW) signatures. Using the Higgs basis simplifies tree-le
The expected increase in both consumption and production of electricity strains the Swedish electricity grid, necessitating both reinforcement and expansion. Concurrently, the need to decarbonise heavy industry is becoming more urgent to achieve the EU Climate neutrality goal by 2050, with hydrogen anticipated as a key player. Hybrid energy systems that combine the generation of renewable electric
Seminar Date: 2024-05-29 Course: BUSN79 - Degree Project in Accounting and Finance Authors: William Gustafsson and Jacob Linder Examiner: Anna Glenngård Five key words: CEO letters, sentiment analysis, agency theory, firm performance, Tobin's Q. Purpose: Discern with the help of a new machine learning model whether the sentiment expressed in CEO letters can offer meaningful insights into
When starting and running a new business, entrepreneurs often face stressors and sleep turbulence such as insomnia that disrupt their daily activities. These challenges frequently result in increased exhaustion, which negatively affects cognitive functioning and entrepreneurial performance. Drawing on existing research, I introduce a conceptual framework to gain valuable understanding into the int
Considering a panel data of 23 countries from different income levels, this research aims to understand the role of governmental quality in mediating the effects of income inequality on CO2 emissions in the period between 1990 and 2020. Using system-GMM, results indicate that good governance is indeed a crucial factor in establishing the direction of the relationship between income inequality and
The following research paper examines the impact of varying environmental regulation stringency on the landscape of green technological innovation in the maritime industry from 2006-2020. Additionally, the paper explores the potential indirect effect of these innovations, induced by stringency levels, on industry competitiveness. The research is grounded in a theoretical framework primarily drawin
The most prevalent joint disease in adults is osteoarthritis. The knee joint is the joint which is the most affected by osteoarthritis, with mechanical overloading being one of the causes. While no cure exists for osteoarthritis, many different treatment options are available. One alternative is to wear a knee brace on the affected leg. This aims to slow down the progression of osteoarthritis to p
Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. Such impacts include CO₂ fertilisation, found to be an important driver of the global greening trend. By increasing leaf photosynthesis and enhan
Intermarriage patterns are often referred to as a step in the social assimilation. However, previous research on is ambiguous in its result concerning differences in intermarriage pattern between genders. According to the theory intermarriage patterns are both influences by preferences and opportunities. This thesis conducts a conditional fixed effects logistic regression to analyses the intermarr
Since 1988 there have been international attempts to regulate banks with the Basel Rules; despite these international efforts to regulate banks within the Basel Rules, the rules have been insufficient. The financial crisis of 2008 highlighted the importance of regulatory oversight in the banking sector. The crisis resulted in strengthened regulatory approaches worldwide, within the USA and Europe,
In recent years, the interrelation between neurodivergent conditions such as ADHD and entrepreneurial activities has received increased attention within academic research. While several studies indicate that individuals displaying ADHD symptoms show elevated levels of entrepreneurial intention and action, other studies found that these do not necessarily translate into entrepreneurial success. Whi
Long life is a typical feature of individuals living in cooperative societies. One explanation is that group living lowers mortality, which selects for longer life. Alternatively, long life may make the evolution of cooperation more likely by ensuring a long breeding tenure, making helping behaviour and queuing for breeding positions worthwhile. The benefit of queuing will, however, depend on whet
Diabetes is not a single homogeneous disease but composed of many diseases with hyperglycaemia as a common feature. Four factors have, historically, been used to identify this diversity: the age at onset; the severity of the disease, i.e. degree of loss of beta cell function; the degree of insulin resistance and the presence of diabetes-associated autoantibodies. Our broad understanding of the dis
The role of the discontinuity of the exchange-correlation potential of density functional theory is studied in the context of electron transport and shown to be intimately related to Coulomb blockade. By following the time evolution of an interacting nanojunction attached to biased leads, we find that, instead of evolving to a steady state, the system reaches a dynamical state characterized by cor
Objective: Oxidation of LDL plays a key role in the development of atherosclerosis. HDL may, in part, protect against atherosclerosis by inhibiting LDL oxidation. Overexpression of HDL-associated apolipoprotein M (apoM) protects mice against atherosclerosis through a not yet clarified mechanism. Being a lipocalin, apoM contains a binding pocket for small lipophilic molecules. Here, we report that
School psychologists have a new and stronger position in Sweden’s educational system than earlier. For example, as of July 2011, all Swedish students ages 6 through 18 have guaranteed access to school psychology services. The school psychologists’ roles are to be active participants and coworker in the student health service team, working to promote student health in the Learning environment. The
We use the Swedish compulsory school reform to estimate the causal effect of parental education on sons’ outcomes. To this end, we use data from the Swedish military enlistment register on the entire population of males and consider outcomes such as cognitive skills, non-cognitive skills, and various dimensions of health at the age of 18. We find positive effects of maternal education on sons' ski
