Att investera sina pengar på ett smart sätt – så kallad portföljoptimering – är en grundläg- gande utmaning inom finans. Traditionellt har detta byggt på att man försöker förutspå framtida avkastning och hur olika tillgångar samvarierar. Men dessa uppskattningar är ofta osäkra och kan leda till felbeslut. I takt med att maskininlärning blivit allt vanligare inom finansvärlden har nya metoder utvecPortfolio optimization is a central problem in finance, with traditional approaches of- ten relying on forecasts of expected returns and covariances. With the growing adoption of machine learning in finance, return forecasting using ML techniques has become in- creasingly common. More recently, an alternative approach has been proposed where the portfolio weights are learned directly, bypassing th

Policy implementation in large organisations can be viewed as a complex endeavour, especially concerning human rights and recruitment fairness. While Malmö municipality adopts a human rights policy, the challenge of translating these principles into daily operations, especially within the recruitment process, remains a critical area for research. This study analyses how HR-practitioners in Malmö m

When people (repeatedly) choose among items characterized by multiple attributes ( price, quality, brand etc..) they often over-or under-weight certain attributes depending on which features stand out in the choice set. Salience theory explains how these distortions arise in a static setting. I extend the existing salience theoretic model for deterministic choice to a setting in which the decision

Areas experiencing conflict are challenging to examine due to limited accessibility. Remote sensing is a valuable tool that can be used to evaluate the effects of conflict on the environment. Northwestern Syria hosts most of the country’s remaining Mediterranean forests, an ecosystem that is ecologically significant for regulatory ecosystem services. Since 2011, Syria has experienced conflict, whi

Climate change is expected to alter soil nutrient availability and microbial community functionality. Inputs of labile carbon (C) from root exudates can stimulate the decomposition of soil organic matter (SOM) in a phenomenon known as “priming”; driven by microbial demand for limiting resources. Climate-driven changes in resource availability may therefore influence soil susceptibility to priming,

Heart failure is one of the most common causes of hospitalization in Sweden, and 30\% of all heart failure patients need unplanned readmissions within three months, creating a burden on the healthcare system. This project was conducted within the healthcare model "Hospital at Home", where there is currently no systematic follow-up method of heart failure patients. By monitoring those wit

This paper investigates gender dynamics within a sixth-grade English as a Foreign Language (EFL) classroom (approximately 12-year-old students) in Sweden, focusing on how gender is performed and perceived by students and their teacher during classroom interactions. Grounded in the compulsory school curriculum’s mandate to actively promote and embody gender equality, and addressing the scarcity of

Sweden has seen a rise in firearm-related violence in recent years, and Malmö is one of three cities that has experienced a significant increase in these crimes. This study isolates the role of socioeconomic variables as determinants of firearm-related violence, exploring whether socioeconomic disadvantage independently influences the spatial distribution of these incidents in Malmö. The spatial c

Antibiotikaresistens utgör en av de största utmaningarna för modern medicin. Sedan penicillinet började användas har antalet resistenta bakterier ökat, medan utvecklingen av nya antibiotika har minskat. Enligt WHO bidrog bakterieresistens till cirka 1,27 miljoner dödsfall 2019. Utvecklingen av nya antimikrobiella strategier baserade på innovativa angreppssätt är avgörande för möjligheterna till frAntimicrobial resistance is a growing global health threat, and once curable infections are now becoming life-threatening. Still, the discovery of new antibiotics continues to decline. Targeted protein degradation potentially offers a novel antibacterial strategy by leveraging cellular degradation pathways to eliminate bacterial proteins. BacPROTACs represent a promising approach, as they utilize

Purpose: The purpose of this study was to examine consumer-brand relationships in the context of football, focusing on how team performance influences fans’ behavioral intentions in Allsvenskan. It further explored how this relationship is shaped by team identification and fans own perceptions about themselves and their teams. Research Question: What is the impact of a football team’s poor perfor

This thesis aims to illustrate how Environmental, Social, and Governance (ESG) scores influence both shareholder perception of firm performance and actual firm performance within Emerging Market Multinational Enterprises (EMNEs). As sustainability becomes a priority in global markets, EMNEs are often subject to increased investor scrutiny due to distinctive challenges and standards present within

This thesis takes its departure in the critical marketing scholarship where the scholars diverge into conflicting perspectives—the Market either being un-politicizing or de-politicizing. The aim of the research, therefore, was to contribute to the critical marketing stream of literature by reconciling these theoretical tensions. We conducted this research with an empirical case of a contemporary c

Nya molekyler blockerar vattenkanaler som främjar tumörutveckling I detta projekt upptäcktes två nya molekyler som stänger aquaporin-3, en viktig vattenkanal i våra celler. Projektet kan öppna nya vägar för cancerbehandling genom att inaktivera ett centralt stödsystem för tumörtillväxt. Aquaporiner är små, specialiserade proteiner som bildar kanaler i cellmembranen. De kontrollerar vattenflödet This thesis identified two novel inhibitors of aquaporin-3 with comparable potency to the current leading compound, DFP00173. This achievement was based on the hypothesis that new aquaporin inhibitors could be developed by building upon the chemical structure of DFP00173. Aquaporins are a class of transport proteins responsible for the transport of water through the cell membranes. Aquaporin-3 is

År 2022 stod bygg- och fastighetssektorn för cirka 34 % av Sveriges totala energianvändning, där uppvärmning utgjorde den största andelen. Mot bakgrund av nationella och internationella klimatmål finns ett behov av att minska energianvändningen inom denna sektor. Detta examensarbete syftar till att undersöka hur boendebeteenden påverkar energianvändningen i ett flerbostadshus från 1960-talet, med This thesis investigates how occupant behavior affects energy use in multi-family buildings, with a particular focus on window airing. The study is centered on a 1960s residential building in Malmö, Sweden, equipped with a mechanical exhaust ventilation system. Using a combination of survey responses and measured data from a re-search project, occupant airing habits were analyzed and translated in

This study examines effective strategies for Swedish multinational companies to manage corruption risks in high-risk markets. Using Scania as a case study, it explores the gap between formal anti-corruption policies and actual practices, and the role of post-scandal reforms and NGOs, particularly Transparency International, in shaping corporate responses. While Swedish companies perform well domes

Under åren 1951–2002 släpptes en mängd på 2600–5000 ton PFAS ut i miljön. Det låter kanske inte så farligt. Men vad händer med miljön när denna mängd ökar? PFAS har konstaterats ha negativa effekter på daggmaskar, jordlevande bakterier och markhälsan. Dessa organismer är avgörande för att våra ekosystem ska fungera och för att vi ska kunna odla och bruka marken. Ändå är kunskapsläget kring PFAS påDuring the years 1951–2002, an amount of 2600–5000 tons of PFAS was released into the environment. The widespread occurrence of PFAS substances can have negative consequences for microbial species and communities within ecosystems, which is ex-pected to have negative effects also for higher trophic levels. Therefore, the purpose of this literature study was to compile information on which identifi
