In this thesis it was evaluated whether it is possible to risk-adjusted outperform the naive, buy and hold, approach for Swedish, listed investment companies. The key metric for this objective was, first and foremost, the Sharpe ratio and secondly the Sortino ratio. To do this, a random forest model was used along with a regime filter. The prediction horizon was one day meaning that at the end of
With the development of high-throughput sequencing technology, the acquisition of large-scale human genome variation data has become increasingly prevalent, offering new opportunities for biomedical research. Therefore, obtaining meaningful information from high-throughput data has become a key task in related scientific research fields. However, how to quickly identify potential pathogenic sites
Although Fourier Neural Operators (FNOs) are computationally efficient and theoretically mesh-independent, their standard formulation assumes periodic boundary conditions and rectangular domains. When applied to non-periodic conditions, FNOs often exhibit oscillations, edge effects, and reduced accuracy. To mitigate these issues, this study investigates modifications to the baseline FNO, including
I denna uppsats beskrivs en lagändring som skedde 1863 som resulterade i att judar fick rätt att gifta sig med kristna i Sverige. Syftet med uppsatsen är att förstå den bakomliggande kontexten och att sätta lagstiftningsprocessen i ett sammanhang för att därefter jämföra denna med samma process i Danmark. På detta sätt undersöks vilka likheter och vilka skillnader som funnits mellan länderna. För The Enlightenment period brought new freedoms to the Jewish minority, established in Sweden after the Jewish Declaration of 1782. In 1838 the Jewish Declaration was abolished, however, no new regulations regarding intermarriage between Jews and Christians were established, and it remained that way until the legislation of 1863. As a result of the process of emancipation during the Enlightenment pe
Utgångspunkten för uppsatsen är Svea hovrätts uppmärksammade dom i mål B 2457–23 (Swedbank-domen). Domen rörde Swedbanks tidigare vd, Birgitte Bonnesen, som dömdes för grovt svindleri på grund av att hon undanhållit information om misstänkt penningtvätt i bankens estländska verksamhet. Eftersom svindleribrottet sällan prövas i domstol har Swedbank-domen stor betydelse för hur verkställande direktöThe starting point of this thesis is the widely discussed ruling by the Svea court of Appeal in case B 2457–23 (the Swedbank-case). The case concerned Swedbank’s former chief executive officer (CEO), Birgitte Bonnesen, who was convicted of gross swindle for withholding information about suspected money laundering in the bank’s Estonian operations. Since swindle cases are rare, the Swedbank-case is
I samband med utbildning inom digitala verktyg samt VFU kopplat till EDI väcktes intresse att undersöka vilka kunskaper som behövs för att undervisa i dator som instrument samt vad som ingår inom InSå-undervisning för en EDI:st på estetiska programmet. Detta resulterade i tre forskningsfrågor relaterade till EDI-undervisning på gymnasieskola: (i) Vilka ämneskunskaper inom EDI anser EDI-lärare behöIn relation with education regarding digital tools as well as internships related to EDI an interest was developed in researching what subject knowledge is needed in teaching this instrument, as well as what teachers incorporate in their instrument lessons on a high school level. Three research questions emerged from this in relation to primary instrument teachings on a high school level: (i) What
This study aimed to examine and analyze how healthcare social workers in paediatric care describe their experiences of the organizational conditions surrounding their work in connection with child deaths. The study was based on qualitative interviews with eight healthcare social workers employed in different organizations within the Southern Healthcare Region in Sweden. The empirical material was
Ungdomars välmående har blivit en allt viktigare folkhälsofråga, förklarat av åratal av dokumenterad och ihållande försämring. Stödjande insatser för barn och ungdomar i utvecklingen av socioemotionella kompetenser (SEC) har tidigare kopplats till ökat välbefinnande, men det finns mindre kunskap om dessa kompetensers direkta korrelation med välmående och hur demografiska faktorer som kön, neuropsyAdolescents’ wellbeing has emerged as a major public health concern, driven by years of documented decline. While previous research has shown that interventions targeting social emotional competencies (SEC) have been linked to enhanced wellbeing, less is known about the direct correlation of these competencies and mediating effects of factors such as gender, neurodevelopmental disorder, and grade.
Sociala medieplattformar, såsom TikTok, är populära bland miljarder användare världen över. Online, videos när man dansar eller sjunger skapas och tittas på men andra typer av videos finns också. Som medicinsk information eller djupt personliga anekdoter om att leva med mental ohälsa. Denna studie hade som syfte att undersöka hur sökordet ‘OCD’ porträtteras på tiktok, ur perspektivet av en ny anväSocial media platforms, such as TikTok, are widely popular with billions of users. Online, videos of people dancing and lip-syncing are being made and watched. But other types of content such as medical information and deeply personal stories of mental health are also being shared.

Parasitoids foraging for larvae of Drosophila flies can use odours of adults of their hosts as well as odours of the food of their host larvae. Adult Drosophila deposit volatile aggregation pheromones into a substrate when mating and ovipositing. In this paper three species of parasitoids with different degrees of host specialization are compared in bioassays with regard to innate responses to agg
