This doctoral thesis consists of four independent research papers. All papers are empirical and cover the area of financial market risk, with a particular focus on systemic risk and volatility in financial markets.The first paper analyzes the joint effect of centrality and other characteristics that are essential in determining banks’ systemic importance. Specifically, centrality is treated as a

In Europe, all new houses built require an energy declaration showing the expected energy consumption during use. However, there is often a discrepancy between the calculated and the actual energy consumption. Some claim that in general the difference is on the positive side for wooden buildings, with real energy consumption being lower than predicted. This could be an effect of thorough and long-

The role of the gaseous messengers NO and CO for β-cell function and survival is controversial. We examined this issue in the hyperglycemic-hyperinsulinemic ob/ob mouse, an animal model of type 2 obese diabetes, by studying islets from obese vs lean mice regarding glucose-stimulated insulin release in relation to islet NO and CO production and the influence of modulating peptide hormones. Glucose-

This dissertation is about the introduction of school television in Sweden during the 1960?s. It focuses partly on formal and institutional attitudes and values, as in the educational system, and it is partly an investigation of the actual programmes made. The introduction and forming of school television is seen as a consequence due to many factors. It was the time of a growing welfare society wh

Purpose – This study aims to enable robotic friction stir welding (FSW) in practice. The use of robots has hitherto been limited, because of the large contact forces necessary for FSW. These forces are detrimental for the position accuracy of the robot. In this context, it is not sufficient to rely on the robot’s internal sensors for positioning. This paper describes and evaluates a new method for

Translating machine learning research into clinical practice has several challenges. In this paper, we identify some critical issues in translating research to clinical practice in the context of medical image segmentation and propose strategies to systematically address these challenges. Specifically, we focus on cases where the model yields erroneous segmentation, which we define as corner cases

Public policy conflicts emerge when feelings of scarcity and different interests dominate interactive process among the government and the public. The stakeholders struggle in a lower violence capacity but broad range of conflicting issues. Thus, some parties may use cooperative or/and competitive conflict management approaches to achieve their goals. This thesis argues that different political st

This study investigates the feminisation of the Swedish commercial bank sector between 1885 and 1937, during which time the female labour share increased from 10 to 27 per cent. More specifically, it is examined why the banks hired women, and why they did not hire women to an even greater extent. The study employs a queue-theoretical framework, and a micro-level panel database constructed from the

There is a shortage of adequate, affordable shelter all over the world. Many households have shelter, but of unacceptable quality with respect to crowdedness, hygienic standard, indoor comfort, safety, security of land tenure, neighbourhood environment. Other families cannot afford their own shelter, but live with relatives or friends under very temporary conditions. Those who cannot afford the ho

Breast cancer is the most common cancer type among women. The 5-year survival rate for invasive breast cancer is generally good at approximately 80-85%, however it is not uncommon for late recurrences to develop – the relative survival at 15 years is approximately 60%, in contrast to for example uterine cancer where the 5-year is about 80% and very few late deaths occur (80% survival at 15-years).

The Base of the Pyramid (BoP) refers to 4 - 4,5 billion people in the world, who are living on less than a few dollars per day. This majority of the world's population has a little resources and is usually considered as a group with no purchasing power and therefore is currently unserved and underserved by current products and services. However, more than any others, the low-income consumers a

Tetra Pak, a global leader in packaging solutions, seeks to optimize inkjet printing as a more flexible alternative to traditional methods. Although inkjet printing offers rapid design customization and reduced waste, its performance is hindered by issues such as unwanted satellite droplets. Capturing the formation of these droplets at microsecond timescales demands specialized experimental method

Denna studie behandlar Högsta domstolens avgörande den 5 december 2023 i det uppmärksammade PFAS-målet. Fallet handlade om personer som fick en förhöjd risk att drabbas av sjukdomar och negativa hälsoeffekter till följd av en PFAS-exponering. Frågan om risker i sig själva kunde utgöra en ersättningsgill personskada togs därmed upp till prövning. Domen är viktig för skadeståndsrätten ur ett rättsutThis thesis examines the ruling by the Swedish Supreme Court on December 5, 2023 (T 486-23). The case, which has received a lot of attention in Swedish media, was about people who had an increased risk of catching diseases and other negative health effects because of a PFAS contamination. The question, which the Supreme Court had to decide upon, was whether risks themselves can constitute a reimbu

Wind energy has been established since before the 2000s and has experienced significant growth, particularly influenced by documents like the Kyoto Protocol and the Paris Agreement, which shaped global perspectives on sustainability. While wind energy has contributed to desired sustainability goals outlined in these documents, it still confronts numerous challenges regarding circularity and achiev

Addressing key environmental concerns during humanitarian assistance is critical to prevent additional hazards, reduce risks, and to not further increase the vulnerability of disaster-affected populations. However, the environment remains an underappreciated cross-cutting issue within the humanitarian sector and efforts to systematically integrate environmental concerns into humanitarian assistanc

This report describes the development and design of a new concept for a lifting device in Tetra Pak’s R1 filling line. It is important that the problems and challenges with the current design, the Tetra Pak R1 Elevator, is fathomed to get a better understanding of what was aimed to achieve in this thesis and why. The purpose of the Tetra Pak R1 filling line is to automatically fold, fill and seal

Computer-Assisted Language Learning, more simply abbreviated as "CALL", dates back to the 60s, 70s and 80s. Tested in language laboratories, pioneer CALL software was limited to very simply mechanical exercises on a stationary PC machine. By the year of 2016, product innovation has brought CALL software development into a new dimension. Today, we not only witness the growth of learning m

Gig-ekonomins intåg på den svenska arbetsmarknaden har väckt många arbetsrättsliga frågor. Den här uppsatsen behandlar en av de frågorna, nämligen hur de traditionella arbetstagar- och arbetsgivarbegreppen står sig inom ramen för gig-ekonomin. Att det uppkommer arbetsrättsliga problem vid tillämpningen av begreppen beror på att den rättsliga utgångspunkten för arbetsrättens tillämpningsområde är eThe rise of the gig economy in the Swedish labour market has lead to several legal questions concerning labour law. This essay aims to discuss one of these questions, namely how the traditional concepts of employee and employer are holding up in the gig economy. The reason for this legal issue is that the overall departure of the applicability of Swedish labour law is a bilateral labour market wit

The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S

This thesis purpose is to look at British media’s coverage of Chinese developmental involvement in Africa, particularly at how the most-read newspapers in the UK have written about the situation, and how they have used media framing when reporting on it. As media can have an enormous impact on people’s perception of certain situations, this paper’s aim is to analyse the media discourse and offer a
