Freshwater systems are active components of the global carbon cycle and contribute to global CO2 emissions. Freshwater studies in the Arctic are underrepresented, especially regarding lakes and their Dissolved Organic Carbon (DOC) reactivity and composition dynamics. DOC is a main part of DOM (dissolved organic matter), which drives processes central to carbon cycling, influences chemical and biol
Syfte: Syftet med denna kvantitativa studie är att förstå sambandet mellan hur synen på precisionsmarknadsföring påverkas av dess datainhämtning. Vidare vill studien undersöka hur inställningen till precisionsmarknadsföring påverkar varumärkesattityd och köpbeteende hos konsumenten. Metod: Uppsatsen är en kvantitativ tvärsnittsstudie med deduktiv ansats som nyttjar en enkät som empiri. Enkäten de
Purpose: The thesis aims to address the different roles incumbent firms can take in the emerging plant-based ecosystem and to contribute with new understandings related to these ecosystems. Theoretical framework: The theoretical foundation for the thesis is rooted in theories on systems thinking, ecosystems and with a discussion around the roles that are inherent in ecosystems. This is accompanie
Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. To allow faster acquisition speeds, we explore a deep-learning approach that applies super-resolution and image denoising to fast time-resolved tomograms. The domain translation algorithm
Effectively utilizing Big Data can be a challenge for many companies. Due to its volume, many aspects of the data processing pipeline such as storage, retrieval and usage may quickly become problematic. For example, it could be difficult identifying the relevant metrics when analyzing a service failure. Visualizing and deriving insights from the data could also prove to be quite onerous. Immersive
Numerous African governments are actively implementing diverse strategies to attract increased foreign direct investments (FDI) to bolster their economies. However, there remains an ongoing debate regarding the impact of FDI on economic development, particularly concerning healthcare. Furthermore, there is a notable lack of understanding regarding the influence of Chinese FDI on the African health
Forecasting wind has always been an interesting subject, and as large parts of the world are relying more on wind for power production it is becoming even more important to have reliable forecasts. Probabilistic forecasts, where distributions are predicted in contrast to deterministic forecasts, are impor- tant for informed decision making. We apply two methods based on conformal prediction for pr
Online shopping is gradually becoming a daily behavior in people's lives, and advertising marketing methods based on short videos are also playing an increasingly important role in this trend. Different from pictures and texts, it combines sound and picture, is easy to spread, and contains a lot of information, which conforms to people's habit of using fragmented information. In this case,
This thesis engages with Western European funding for queer movements in Georgia by asking how these donors affect the local movements, transnational politics and the power dynamics in Georgia. It pursues these inquiries by analysing the Western European understanding of queer activism and how donors support queer movements in Georgia; and the Georgian activists perceptions and suggestions for imp
PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. The rapid expansion of roof mounted PV system installation on co
This thesis examines the impact of macroeconomic shocks on adolescents health, specifically those aged between 14 and 18 years. Using data from the Youth Risk Behavior Surveillance System (YRBSS) covering U.S. states from 1999 to 2019, this study investigates various health outcomes and behavioural variables among high-school students. A two-way fixed effects model, that accounts for state- and ye
Polisen i Sverige har fått tillsatt målet av regeringen om att ha 26 200 anställda poliser till årsskiftet 2024/2025, tusentals mer än antalet verksamma poliser i dagsläget. Poliser väljer av olika anledningar att sluta i förtid eller säga upp sig, främst på grund av lön och organisationskulturen. Det finns olika teorier om kallelse till yrke och hur uppfattningen framkommit, men ett genomgående t
”Har du gjort gehörsläxan?” är en kvalitativ intervjustudie om lärare och elevers tankar kring gehörslära. I studien har 7 elever och 6 lärare på olika utbildningsformer intervjuats. Studiens forskningsfrågor behandlar ämnen såsom hur gehörsövningar och -strategier kan översättas från lektionssalen till övningsrummet, vilka faktorer som påverkar elevernas möjlighet till enskild övning, samt vilka ‘Have you completed the ear training homework?’ is a qualitative interview study on teachers’ and students’ thoughts about ear training. In the study, 7 students and 6 teachers from different forms and levels of education were interviewed. The research questions of the study address topics such as how ear training exercises and strategies can be translated from the classroom to the practice room,
This study investigates the effects of violating deontic constraints on the Japanese conditional markers to and ba. Via an online survey, native speakers reviewed sentences containing violations of these constraints, evaluating their own ability to understand the sentence and the proficiency of the sentences’ authors. Additionally, they were asked to correct sentences they rated poorly, and determ
Drunk Elephant, a skincare brand known for its clean ingredients and cheerful branding, has experienced a surge in popularity driven by Gen Alpha's unexpected adoption on social media. While this newfound audience has boosted sales, concerns are mounting regarding the impact of early exposure to beauty standards and consumption habits on young children. This business case explores the challeng
The knee menisci distribute and dampen mechanical loads. Vulnerability to injury and disease of the meniscus is a global issue, particularly concerning osteoarthritis. The connection between the breakdown of meniscal tissue and its mechanical response is not entirely understood. This thesis seeks to contribute to filling this knowledge gap by developing and implementing a digital volume correlatio
The aim of this thesis is to explain the widely different opinions about the Catholic Professor of Christian Ethics Germain Grisez's (1929-2018) ethics. While some commentators see his ethics as legalistic and deontologic, others think that it’s anti-legalistic and eudaimonic. The Aristotelian and Kantian positions are drawn upon as frames of reference. The focus of the thesis is Grisez's
We call a number representable by some given integers $a_1,\dots,a_n$, if the number can be expressed as a linear combination of $a_1,\dots,a_n$ with non-negative coefficients. This thesis explores the properties of non-representable numbers, with the main focus on the greatest such number called the Frobenius number, denoted by $g(a_1,\dots,a_n)$. We derive a simple formula when $n=2$ for the Fro
