The thesis studies the problem of predicting large covariance matrices, a central challenge in modern portfolio theory. In portfolios with many assets, the large number of covariance terms makes prediction difficult, often causing traditional methods to suffer from either substantial estimation bias or variance. To address this, the thesis proposes an approach that adapts conditional autoencoders,
Consumer brands increasingly enter co-branding collaborations with popular streaming series, seeking to transfer cultural meanings and pre-existing emotional attachments directly onto their brand and products. This study addresses a significant research gap by examining co-branding with streaming series from a personal care brand perspective, asking which factors influence consumer purchase intent
Denna studie ämnar belysa hur sexualbrottsoffer konstrueras i samtida svensk nyhetsrapportering. Studien utgår från Nils Christies teori om det ideala offret men kompletteras med teorier om genus och socialkonstruktionism för att belysa hur media förmedlar och upprätthåller normer kring offerstatus. Studiens metod utgörs av en innehållsanalys med både kvalitativa och kvantitativa inslag, där empir
This study aims to assess the performance and importance of mangrove ecosystem services, focusing on supporting, provisioning, and regulating, and to investigate temporal changes in mangrove cover in Maputo Bay, Mozambique. It also examines the drivers behind these changes. The research questions address stakeholder perceptions of ecosystem services and their potential trade-offs, temporal changes
This thesis investigates how players of Grand Theft Auto V and Red Dead Redemption 2 morally make sense of in-game crime. The study is motivated by the fact that video games are important cultural spaces where players not only watch crime and violence but also participate in them through play. While previous research on violent video games has often focused on aggression and media effects, this th
Abstract In this thesis, I examine intra-migrant boundary-making in Sweden, focusing on Iranian migrants’ attitudes toward other Middle Eastern migrant groups. Drawing on Jock Young’s criminology of vindictiveness, this study situates othering within broader dynamics of ontological insecurity, perceived status positioning, and moral differentiation in late modern societies. The aim of this thesis
This thesis examines how young people in Finland make sense of profit-oriented drug selling and construct drug dealer identities. Drug use and related harms have increased globally in recent years. In Finland, an increase in minors selling drugs for financial profit has been noticed by the police and a non-governmental youth work organization Children of the Station. The aim of this thesis is to e
The darknet cryptomarkets marked an evolution in the drug trade by providing technological anonymity and security for both sellers and buyers. Together with their surrounding forums, they form an ecosystem where participation and access to its safety and harm reduction benefits depend on digital capital, a resource that is not equally available to all. This study examines how digital capital influ
This thesis investigates how analyst coverage and blockholder ownership shape the informativeness of insider purchases in a market characterized by concentrated ownership, dispersed analyst coverage, and high retail participation. While prior research has established a negative relationship between analyst coverage and insider purchase abnormal returns in the U.S., whether this relationship genera
Ultraviolet-C (UV‑C) irradiation is a promising non-chemical complement to conventional cleaning processes in processing units intended for cleaning items such as utensils, textiles and laboratory equipment. This thesis evaluates the technical feasibility of integrating UV‑C light-emitting diodes (LEDs) into such units, with a focus on liquid-phase treatment of the washing liquid. A design-space e
Carbohydrate chemistry has mainly focused on five- and six-membered sugars, while seven-membered sugars remain relatively unexplored despite their potential bioactivity. Synthesis of seven-membered sugars can be performed by a ring expansion from a six-membered sugar. This project focused on synthesizing a precursor for a seven-membered sugar by regioselective protection and oxidation. The target
Keywords: manosphere, male loneliness, compensatory consumption, consumer responsibilization, netnography Purpose: The purpose of this study is to expand the understanding of how digital communities construct consumption as a collective remedy to affective social problems, examined through the case of male loneliness within the manosphere. Theoretical perspective: By synthesising three theoretic
Pågående urbanisering och klimatförändringar ställer ökade krav på hållbar stadsutveckling i svenska storstadsregioner. Samtidigt minskar tillgången till grönområden i tätbebyggda miljöer, vilket påverkar både ekosystemtjänster och människors livskvalitet. Gröna tak har under senare år lyfts fram som en möjlig naturbaserad lösning för att möta dessa utmaningar. Syftet med denna studie är att underOngoing urbanization and climate change place increasing demands on sustainable urban development in Sweden’s major metropolitan regions. At the same time, access to green spaces in densely built environments is decreasing, affecting both ecosystem services and human quality of life. In recent years, green roofs have been highlighted as a potential nature-based solution to address these challenges
Causality is a fundamental requirement for physical consistency in many-body approximations. In the context of Green's functions, causality requires a positive spectral function and analyticity in the upper half of the complex-frequency plane. These properties are not guaranteed by approximate methods, and formal proofs of causality for the underlying approximation schemes are often difficult
Sustainability-driven consumer brands face strategic challenges when expanding internationally, as institutional environments shape not only market access but also how legitimacy for the brand and product category must be constructed across markets. This thesis examines how sustainability-driven consumer brands navigate divergent institutional environments in their international market entry and s
This thesis investigates how the roles, relationships, and coordination mechanisms among stakeholders influence the integration of energy resilience in urban development (UD) projects, a challenge increasingly recognised as governance-related rather than technical. Drawing on stakeholder and resilience theory, the thesis explores how stakeholders interpret their positions and influence within UD p
This thesis examines how private equity ownership shapes consumer brand equity during the holding period, drawing on fourteen semi-structured interviews with investment professionals across five Nordic PE firms and four consumer brand professionals. The central finding is that PE ownership neither preserves nor destroys brand equity, it instead reconstitutes it. Short-term performance metrics cro
The aim of this study is to explore Swedish upper secondary students’ attitudes towards reading fiction in and outside of school. A central starting point is the alleged reading crisis that is widely discussed in Swedish media and politics. Focus is particularly placed on the phenomenon of reading for pleasure and reading motivation through a phenomenological lifeworld perspective, in combination
De-influencing has emerged as a prominent form of social media content that encourages consumers to question or avoid product purchases. Existing research has primarily examined de-influencing as a communicative or persuasive event, focusing on its influence on attitudes, credibility, or purchase intentions, while paying limited attention to how it becomes integrated into consumers’ everyday shopp
