Matematikämnet är ett ämne där läroboken dominerar undervisningen och där det höga användandet av läroboken möts av kritik. Tidigare forskning visar att lärobokens innehåll får konsekvenser för elevers lärande, särskilt vid läroboksstyrd undervisning. Som konsekvens av lärobokens innehåll får lärarens användning av läroboken stor betydelse och studier visar att lärares användning skiljer sig åt. A
This thesis is partly about the phenomenon of how sound can be perceived differently in a comparison between the perceived sound and the experience of the sound, but also about the importance of ear training generally for music making. In a similar way we use language to think, musicians can think the music silently in advance. In English, the term audiation has been used to describe this phenomen
The search for non-invasive tools to monitor stress has gained significant research attention. Heart rate variability is one such measure commonly analyzed in either the time domain or the frequency domain. This project explores the use of time-frequency analysis, specifically the spectrogram, for this purpose. The study utilizes real data obtained from a cold pressor test and a control session. O
This study examines the potential link between the digital media discourse of the Nordic Resistance Movement (NMR) and the radicalization trajectories of lone-actor perpetrators. Through interpretive content analysis of NMR's digital media utilizing the theory of intertextuality, and the case studies of three lone-actor perpetrators in Sweden, the study seeks to identify similarities and poten
Soccer is witnessing technological advancements in a variety of areas, of which many are dependent on camera calibration. This thesis addresses the challenge of calibrating the extrinsic parameters of cameras used in soccer broadcasts using a monocular view of the field. Accurate camera calibration is essential for various applications such as player positioning, field modelling, and improving the
Uppsatsen undersöker de oberoende, medelstora förlagens villkor på en bokmarknad där just medelstora förlag i allt större utsträckning köps upp av de större koncernerna, läggs ner eller ändrar utgivningsprofil. I uppsatsen intervjuas tre representanter från oberoende, medelstora förlag om deras självupplevda situation, samtidigt som en dokumentanalys av aktuella kulturpolitiska dokument görs för a
Pluvial flooding is a significant and growing issue in Kampala, Uganda, driven by increased urbanization, lack of sufficient maintenance of the urban drainage system and climate change. This study investigates the impact of sediment and solid waste deposition on urban flooding within the upstream part of the Lubigi catchment area. Using PCSWMM, a 1D hydraulic model was developed to simulate variou
In this thesis, a finite square Moiré system placed inside an optical cavity was simulated. Two commensurate angles, θ = 0 and θ ≈ 37 were considered. The fluorescence spectrum was obtained for both angles and for systems with one particle or two particles with opposite spin. The twisted configuration was found to have a richer fluorescence structure compared to the aligned configuration, which ex
Belgium is celebrated for its progressive LGBTI legislation, ranking second on the ILGA index. At the same time Belgian LGBTQIA+ people experience alarmingly high rates of violence and fear. This thesis examines two competing narratives about the relationship between LGBTI legislation and LGBTQIA+ experiences of safety: (1) ‘LGBTQIA+ safety requires state protection’; and (2) ‘LGBTQIA+ safety requ
This thesis investigates the effectiveness of step size control in the numerical simulation of Stochastic Differential Equations (SDEs). The study is divided into a theoretical exploration and a series of numerical experiments. The theoretical section introduces key definitions and theorems, delves into the properties of Brownian motion, and examines the conditions under which solutions to SDEs ca
The current climate crisis is pressuring policymakers to outline what a post-fossil economy might entail. In Norway, many have pointed towards the salmon farming industry as a central part of the country’s green transition. At the same time, the industry has shifted towards increasing use of feed imports from Brazilian soy plantations - the second largest driver of deforestation in the country. Ex
I detta arbete diskuterar jag problematiken kring olika radiometriska dateringsmetoder samt möjligheten att generera noggranna och precisa dateringar. Goda dateringar av nedslagskratrar är en förutsättning för att undersöka intensiteten av nedslag på vår planet, korrelationen till massutdöende eller de hydrotermala system som uppstår efter ett nedslag och pågår i tusentals år. Problem relaterade tIn this study, I discuss the issues related to radiometric dating methods and the possibility of generating accurate and precise ages. Such dating of impact craters is crucial for investigating impact intensity, correlation with mass extinctions, or the hydrothermal systems that form after an impact and last for thousands of years. Problems related to both analytical and geological causes can resu
A lack of somatostatin expressing interneurons (SST INs) is known to be a factor in several neurodegenerative and neurospsychiatric diseases, such as Alzheimer disease, Parkinson’s disease and schizophrenia. Being able to efficiently obtain SST INs in vitro could enable a greater understanding and better treatment of these diseases. The development of SST INs is not yet fully understood, but it is
Our agricultural management practices have been constantly evolving, with significant impacts on both our society, and biodiversity of human-dominated landscape. While the negative effects of agricultural land-use change at local and landscape scales on biodiversity are well documented from regions such as Western Europe, the effect of current and past land-use in areas that have had more complex
Land degradation and soil erosion are considered one of the main threats to ecosystem services and functions, soil stability and activity, plant community structure and biodiversity, and overall life on Earth. Soil erosion is a problem occurring all over Iceland, with an immediate urgency on the Icelandic highlands and rangelands. Currently, over 40% of the country is eroded, steadily causing loss
Climate change is affecting all regions of the globe, causing a shift of temperature distributions. As species try to track their optimal thermal conditions, they are also potentially met with new photic environments. Photoperiod is the main cue for synchronizing migratory birds' circannual rhythms, affecting both their physiology and migration. Thus, their ability to incorporate and adjust to
The decision of when to exchange habitats represents a significant moment for organisms that utilize migration as a strategy to access growth and feeding opportunities surpassing those available in their natal habitat. For juvenile anadromous salmonids, the initial transition from freshwater to the marine environment marks a critical point in the life cycle characterized by high mortality with mig
The central area of Stenshuvud national park in southern Sweden was surveyed regarding the lichen species composition and distribution. Similar qualitative investigations of the area have been carried out in the years 1934 and 1987, although this survey further included a quantitative survey of relative frequency per species to enable more accurate monitoring in the future. Together, the three s
