For unital and commutative algebras over an algebraically closed field, any inclusion of finite codimension can be characterised as a chain of inclusions of codimension 1. We investigate the behaviour of such chains when the said algebras are ideal subalgebras. That is, when they are sums of the base field with an ideal. So called single clustered polynomial subalgebras can be guaranteed to be con
The archaic witch Circe from Greek mythology has been an enduring figure in history in Western literature and English-speaking cultures. The character has undergone multiple adaptations and is seemingly restricted to the archetype of a villainous femme fatale, symbolising the threat of wilderness and female sexuality. In Miller's novel Circe (2018), the character undergoes another transformati
ChatGPT är ett lättillgängligt AI-verktyg som många studen- ter använder i sina studier. Däremot finns det idag delade åsikter kring eventuella konsekvenser av användandet på lång och kort sikt. Med utgångspunkt i studenters utsagor syf- tar uppsatsen till att öka kunskaperna kring hur användande av ChatGPT upplevs inverka på lärande samt hur det poten- tiellt skulle kunna återspeglas inom arbetsl
This paper explores the impact of quantitative easing on debt in Sweden and the Euro area. The study examines the debt levels of both households and non-financial corporations and compares the results between Sweden and the Euro area. Using the historical balance sheets of the Riksbank and the European Central Bank, three hypotheses are tested using OLS time series regressions. The first hypothesi
Syftet med denna uppsats är att beskriva och analysera forskning om icke-hierarkisk organisationskultur, utifrån hur den påverkar medarbetarens roll i organisationen. 22 studier används för att beskriva icke-hierarkiska organisationskultur, där olika kontexter och fokus behandlas. Ledarskap, kommunikation, organisatoriskt lärande, organisationskultur blandas med kontextuella skillnader där arbetsk

Background: The utility of whole-genome sequencing (WGS) in diagnosing cardiomyopathies (CM) and heritable connective tissue disorders (HCTD) is limited by high costs and ambiguous results. Letting the referring physician decide whom to refer for WGS increases the absolute number of positive patients identified but lowers clinical yield (proportion of patients identified with a pathogenic gene var
As the amount of wind power in electricity production increases it becomes more important that they are able to provide ancillary services to support power system stability. This thesis investigates how a generic wind power plant can provide reactive power for voltage support. To represent a generic wind power plant, the Western Electricity Coordinating Council’s generic Renewable Energy System mo

The traditional assumption of normally distributed returns in portfolio optimization often fails to capture real-world complexities. This thesis investigates how higher moments – skewness and kurtosis – enhance portfolio optimization by addressing these complexities. Using polynomial goal programming and Bayesian shrinkage estimators, the study constructs and evaluates portfolios optimized for hig
Investors are constantly seeking information that can provide a competitive advantage in the market. Using online platforms along with traditional media sources supply a constant source of information available to investors. Among the available information, Google Trends scores provide insights into investor attention and sentiment. To understand whether there is a relationship between Google Tren
Bakgrund: Våld mot äldre från vårdpersonal beräknas vara ökande, speciellt i en hemmiljö där vård bedrivs. Att vårdpersonal utsätter äldre för våld inom äldreomsorgen är trots större uppmärksamhet under senare år, fortfarande otillräckligt undersökt. Syfte: Undersöka vårdpersonalens uppfattningar om våld mot äldre inom hemtjänst och hemsjukvård. Metod: En semistrukturerad kvalitativ intervjustud
The thesis describes and analyzes individuals' experiences of reduced working hours with retained salary, as well as how this could potentially enable an improved work-life balance. It also investigates how participants experienced pros and cons with reduced working hours. The topic is relevant due to the ongoing societal debate about whether the current 40-hour workweek in Sweden shoul
This paper investigates the impact of Trump’s opinion polls on U.S. Treasury yields during the 2016, 2020, and 2024 presidential elections. Focusing on both 2-year and 10-year yields, the study examines short- and long-term perspectives and compares the effects across the 2016 and 2024 elections. Using a GARCH-in-Mean model and the “Trump-Head-to-Head Momentum” (THHM) variable, we test three hypot
Small and Medium – sized enterprises (SMEs) have historically underperformed against large enterprises in winning public procurement contracts both by measure of number of contracts and share of total contract value. Thus, both European Union and Swedish regulators have put forward recommendations on best practice to increase the presence of SMEs in public procurement. This study examines the impa
This thesis examines the descriptions, and conceptions of the mother and motherhood, present within the association Social Democratic Women in Sweden during the years 1920-1925. Additionally, the study analyzes how the Social Democratic Women in Sweden argued for women’s access to the public sphere through their imagined motherliness. In the thesis, the mother’s imagined place, mission, qualities
Bakgrund: Tidigare forskning har visat att kreativa aktiviteter som körsång kan ha hälsofrämjande effekt fysiskt, psykiskt och socialt. Det finns en kunskapslucka i arbetsterapeutisk forskning kring upplevelsen av körsång som kreativ metod. Det är relevant att utforska körmedlemmars upplevelser av aktiviteten för att utforska hur den bidrar till välbefinnande. Syfte: Undersöka körsångares upplevel
