Portfolio optimization involves selecting assets to maximize risk-adjusted returns, typically using linear methods like Mean-Variance Optimization (MVO). However, such approaches may not fully capture the complexities of financial markets. This study leverages recent advances in machine learning, specifically reinforcement learning with deep neural networks, to identify alternative methods that ma

As the life expectancy continues to increase in Sweden, with an estimated increase of 5 years for women and 6 years for men between 2024 and 2070, there is an increasing need for solutions that enables elderly people, and individuals with a need for extra safety, to live an independent and healthy life. One solution that is under development, is a mobile social alarm in the form of a watch, which

With the rapid growth of software dependencies in critical systems, detecting vulnerabilities early in the development cycle has become a necessity. While extensive research exists on vulnerability detection in low-level languages like C/C++, there is a significant gap in addressing vulnerabilities in higher-level languages, including JavaScript, Python, and PHP. This thesis explores the feasibili

This thesis examines the norms, boundaries, and perceptions surrounding homosexuality in Swedish gay press between 1969 and 1973. The aim is to analyse how normative systems influenced the formation of identity, self-image, and sense of community among homosexual individuals. The aim is also to analyse how heteronormativity and the transgression of norms affected their relationship with society an

Bakgrund: Världshälsoorganisationen (WHO) rekommenderar att barnet helammas under de första sex månaderna. Trots amningens hälsofördelar för både moder och barn har det visat sig att rekommendationerna är svåra att uppnå globalt. Modern upplever psykologiska, fysiologiska och sociala svårigheter med amning. Syfte: Syftet var att belysa mödrars upplevelser av främjande respektive hämmande faktorerBackground: The World Health Organization (WHO) recommends exclusive breastfeeding for the first six months. Despite the health benefits of breastfeeding for both mother and child, it has been shown that these recommendations are difficult to achieve globally. Mothers face psychological, physiological, and social difficulties with breastfeeding. Aim: The aim of this study was to highlight mothers&

I Sverige lever många barn i hem präglade av våld och övergrepp, trots att de har en ovillkorlig rätt till skydd. Umgänge med en våldsutövande förälder, även kallat tvångsumgänge, kan få allvarliga konsekvenser för barnet. När domstolen beslutar om umgänge ska barnets bästa vara avgörande. Vid bedömningen av barnets bästa ska risken för att barnet far illa särskilt beaktas. Syftet med uppsatsen äIn Sweden, many children live in homes marked by violence and abuse, despite having an unconditional right to protection. Contact with a violent parent, often referred to as forced contact, can have severe consequences for the child. When courts decide on contact arrangements, the best interests of the child must be the determining factor. In assessing the child’s best interests, particular consid

Bakgrund: Barnmisshandel är ett globalt problem, som påverkar barn i alla samhällsklasser och miljöer. Vårdpersonal är en viktig och central del i identifieringen av barnmisshandel. Trots det uteblir anmälningar av barnmisshandel i viss mån, även i de länder där det råder anmälningsplikt. Syfte: Syftet var att undersöka vårdpersonalens upplevelser av att identifiera och anmäla barnmisshandel med

Det primära syftet med studien var att undersöka genomförbarheten av dagliga skattningar två gånger dagligen av symtom, psykologisk flexibilitet (PF) och funktion hos vuxna med systemisk lupus erythematosus (SLE). Det sekundära syftet var att undersöka sambandet mellan de vanligaste och mest besvärande symtomen på SLE (dvs. smärta, trötthet, ångest, depression och kognitiv påverkan), hälsorelateraThe primary aim of this study was to assess the feasibility of obtaining twice-daily recordings of symptoms, psychological flexibility (PF) and functioning from adults with Systemic Lupus Erythematosus (SLE). The secondary aim was to investigate the relationship between the most common and burdensome symptoms of SLE (i.e., pain, fatigue, anxiety, depression and cognitive impairment – CI), health r

Det finns ett behov av frågeformulär som dimensionellt mäter psykiskt fungerande hos ungdomar. Den korta versionen av Extended Strengths and Weaknesses Assessment of Normal Behavior (E-SWAN-G) är designat för att mäta centrala förmågor längs kontinuum från stora svårigheter till stora styrkor. Syftet med denna studie var att genomföra en initial psykometrisk utvärdering av E-SWAN-G kortversion medThere is a need for questionnaires that dimensionally assess psychological functioning in adolescents. The short version of the Extended Strengths and Weaknesses Assessment of Normal Behavior (E-SWAN-G) is designed to assess core abilities along continua from severe weaknesses to great strengths. The aim of this study was to conduct an initial psychometric evaluation of the E-SWAN-G short version

This study explores the potential of new building insulation material specifically wood wool in Bhutanese Buildings.

This thesis examines the use of ARMAX models for predicting cryptocurrency trading volumes, with Google Trends data serving as an exogenous variable. The spec- ulative nature of cryptocurrencies suggests that market sentiment, reflected in search trends, could influence trading activity. To test this hypothesis, the predictive performance of ARMAX models is compared to ARMA models across six crypt

Intimate partner violence disproportionately affects immigrant women, who face unique barriers when seeking support. This study explores factors influencing their help-seeking behaviors through semi-structured interviews with professionals in social services.

Aedes aegypti is one of the most lethal disease vectors in modern history, spreading a majority of the deadliest diseases mediated by mosquitos. To try and combat this, mankind has, for a long time, tried to create repellents to keep the insects away. These repellents affect receptors in the mosquitos, keeping them at bay. One receptor that is highly expressed in the mosquito’s prey/host sensory o

Syftet med uppsatsen är att undersöka på vilket sätt det är möjligt att uppnå gemenskap och intensiva känslor i form av collective effervescence. Vi vill även ta reda på vilka ritualer, symboler och kulturella markörer som bidrar till detta samt om detta skiljer sig under en hiphopkonsert respektive en operaföreställning. För att möjliggöra detta har kvalitativa intervjuer med operabesökare, hipho

Barn som placeras i familjehem utgör en utsatt grupp. För att undersöka hur dessa barn kan stärkas kan det teoretiska begreppet resiliens användas. Det finns för närvarande en brist på studier med ett resiliensperspektiv som fokuserar på vad barn i familjehem själva anser stärker dem. Därför undersökte denna studie vad som främjar resiliens hos barn i familjehem, utifrån tre forskningsfrågor: (1) Children placed in foster care are a vulnerable group. In order to investigate what makes these children thrive, the theoretical concept of resilience could be used. There is currently a lack of studies that employ a resilience perspective and focus on what children in foster care believe strengthens them. Therefore, this study explored what promotes resilience in children in foster care, guided b

Arbetsmotivation är ett välutforskat ämne inom arbets- och organisationsforskning, och går att betrakta ur ett flertal olika perspektiv (Tremblay et al., 2009). Med hjälp av självbestämmandeteorin (Deci & Ryan, 1985) syftade denna kvantitativa studie till att undersöka potentiella skillnader mellan inre och yttre motivation i förhållande till kreativitet på arbetsplatsen, samt om dessa skillnaWork motivation is a well-researched topic in work and organizational research, and can be viewed from several different perspectives (Tremblay et al., 2009). Using self-determination theory (Deci & Ryan, 1985) this quantitative study aimed to investigate potential differences between intrinsic and extrinsic motivation in relation to creativity in the workplace, and whether these differences v

In Sweden, there are currently more women than men active in the welfare profession. At the same time, women are also advancing through traditionally male dominated professions to a much greater extent than men that are advancing through traditionally female dominated professions, such as social work. The purpose of this study was to examine if and how male students in social work, during their st
