A novel light use efficiency model for estimating gross primary production across Europe using PROBA-V and Sentinel-3 FAPAR

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

Paths beyond livestock: Exploring farmers’ transformations away from livestock farming in Germany

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

Improving biome classification of tropical grasslands using fire frequency data

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

Thanks, but No Thanks: A Microsimulation of BAföG Eligibility and Non-Take-Up

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

State Aid as a Crisis Management Tool: Observations into EU State Aid Law and Impacts on Member State Discretion

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

The DAX 40 and its SDG Reporting: Symbolic or Substantive?

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

Drömmen om kvinnan : konstruktionen av hegemonisk femininitet och kvinnans plats i den borgerliga kulturen i svensk och brittisk modepress 1830–1855

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

Incorporating Material Characteristics in GSCM for Accurate Channel Modeling in Urban Scenarios

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

Living with nonhuman animals in the city: Street cat caretaking in metropolitan South Korea

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

A Markovian Framework For Optimal Staffing: Balancing Poisson Arrivals And Customer Retention

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

The Childfree Woman: A study of identity construction in Sweden

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

What's in the budget? An economic study of Swedish household consumption

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
