This study aims to examine which discourses regarding drug use can be identified on the social media app TikTok and how drug use is portrayed and constructed on the app. A netnographic study was conducted in which empirical material was collected from TikTok and analysed in a discourse analysis based on social constructivism. From the results, three discourses were identified: a health discourse,

Satellite remote sensing is a powerful tool for modelling gross primary production (GPP) at large scales. While model comparison is a prerequisite for understanding carbon dynamics comprehensively, existing GPP products rely on a limited number of satellite sensors. In this study, the contemporary fraction of absorbed photosynthetically active radiation product derived from PROBA-V and Sentinel-3

Livestock systems significantly contribute to climate change, environmental degradation, public health issues and animal welfare concerns, highlighting the need to reduce livestock numbers. As Germany is a key producer of animal products, this thesis explores the experiences of German farmers who partly or fully transformed away from livestock farming to other agricultural practices. Using the Thr

Tropical grasslands are ecosystems of immense value, both ecologically and socially. Despite this, they are commonly misclassified as degraded forests, partly due to the large role of fire, rather than climate, in limiting the establishment of woody vegetation in those ecosystems. Misclassification can cause misguided management practices to be implemented, which explains the need for improved cla

While the body of literature on the non-take-up of public aid has grown substantially in recent years, a notable gap remains in the literature of non-take-up rates for student aid programs, where research is still extremely limited. This paper examines the non-take-up rate of Germany’s federal student aid program BAföG by creating a microsimulation based on data from the German Socio-Economic Pane

This study examines how different forms of agency facilitate or hinder the reconceptualization of poverty during Sri Lanka's transition from the Samurdhi program to the Aswesuma Welfare Benefit Scheme and analyzes its impact on targeting efficiency. The research addresses a critical gap in comprehending how transformations from income-based to multidimensional poverty measurement frameworks ar

Since 2000, the EU has faced significant economic challenges linked to both the Global Financial Crisis in 2008 and the outbreak of the COVID-19 pandemic in 2020. These challenges triggered the need for urgent intervention on both national and EU levels, which prompted rapid responses from the European Commission. This thesis explores the relationship between EU state aid law and the crisis respon

Purpose: This thesis analyses and assesses how companies in Germany’s DAX 40 demonstrate their adherence to the UN Sustainable Development Goals. It evaluates whether these disclosures are mainly substantive, indicating proper strategic integration, or symbolic, aimed primarily at enhancing reputation, and compares their reporting quality to previous international research. Methodology: This rese

The dream of woman : the construction of hegemonic femininity and the woman’s place in bourgeois culture in the Swedish and British fashion press, 1830–1855. This thesis investigates the construction of hegemonic femininity in British and Swedish fashion periodicals between 1830 and 1855, a period often overlooked in history research. Through an intersectional lens, drawing on theories of fashion

Accurate modeling of wireless channels in urban environments is crucial for the design and evaluation of communication systems. Geometry-Based Stochastic Channel Models (GSCMs) provide a balance between physical retings—an oversimplification that can reduce model fidelity.alism and computational efficiency by simulating Multi-Path Components (MPCs) through simplified ray tracing and stochastic sca

Urban environments have historically been viewed as exclusively human spaces, a notion-challenged by animal and more-than-human geography, which highlights the active roles of-nonhuman animals in shaping life. This research investigates the complex human-nonhuman-animal nexus in urban South Korea by exploring the experiences of street cat caretakers.Their care practices disrupt conventional spatia

Hur många anställda behövs för att kunna balansera kundflödet och samtidigt optimera kostnaderna av medarbetarna? Är det möjligt att beräkna stationära sannolikheter utifrån ett ankomst- och avgångsflöde, som kan användas för att optimera kö-modellen? Om du är chef på ICA, ägaren av en butik, eller en kund som har stått i kö för länge, så har du kanske ställt dig dessa frågor. Det finns olika svaThe main goal of this investigation is to determine the optimal number of cashiers to be employed in a first-in-first-out (FIFO) queuing system, based on the number of customer arrivals, the average revenue generated per customer, and the rate at which each customer abandons the queue, referred to as the reneging rate. This is done by using continuous-time homogeneous Markov Chains to model the ar

This thesis aims to study how voluntarily childfree women express identity in a Swedish society defined by pronatalist norms. Previous research has portrayed childfree individuals as marginalized, stigmatized, and even as an invisible group in Western society. The purpose of this study is to explore evolving narratives by analysing voluntarily childfree women's expression and construction of i

This thesis examines how income affects household consumption in Sweden between 1999 and 2009. Using data from SCB, the study explores how people with different income levels spend their money on various goods and services. The analysis is based on Engel’s law, which suggests that as income increases, the share of spending on basic needs like food goes down, while spending on non-essential or luxu

Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot

I Sverige pågår en elektrifiering av samhället, där transporter, industrier och hushåll i allt större utsträckning försöker övergå till el som energibärare. Detta är en central del i att nå våra klimatmål, men ställer samtidigt höga krav på elsystemets kapacitet. För att kunna planera för ett robust och hållbart elnät krävs en förståelse för hur el används idag. I denna rapport ligger fokus på attThis report aims to develop general synthetic load profiles representing electricity consumption in Swe- dish single-family homes. Based on historical hourly consumption data from Lomma and Helsingborg, provided by RISE, three models – SARIMAX, GRU, and Prophet – were trained and evaluated. To enable comparison and future scalability, the data was normalized by each user’s annual consumption. Amon

This thesis examines how AI-generated works fit within the European Union’s copyright framework and explores alternative legal mechanisms for their protection. With the emergence of generative AI technologies capable of creating content independently, traditional copyright concepts, particularly authorship and originality are being challenged. The thesis begins by outlining the technological basi

This thesis explores the heterologous expression of six fungal enzymes with potential polyurethane (PUR) degrading activity in two strains of the filamentous fungus Aspergillus oryzae: the standard Ory6 and a knock-out variant with disrupted transcription factors to potentially reduce native protease activity. Each enzyme was expressed in three gene formats: a native version (including any introns
