This study focuses on children’s participation in child welfare investigations. Interviews were conducted with four child welfare caseworkers from the social services to understand how they view children’s participation and how they work to support it. The study aims to gain a better understanding of how caseworkers see children being involved, and what factors make it easier or more difficult for

This qualitative study has examined the experiences of work-related stress among Swedish social workers working in human-service organizations. The purpose of this study was to investigate the working conditions of social workers and how these impact their experiences of stress at the workplace. The purpose was also to identify preventative measures for work-related stress. The study uses a qualit

This thesis presents a case study on the application of artificial intelligence (AI) in hydrology using two approaches. This topic was chosen since AI is an important tool, and water is a vital resource. The first case is on leakage detection with artificial data, while the second is on precipitation prediction with real data. For leakage detection, a random forest (RF) model and an artificial neu

The aim of this thesis was to investigate how the dimensions, placement and orientation of a combustible material can affect both fire characteristics such as flame height and heat release rate, and material characteristics such as surface lining classification. The extent of the effects was examined using a simplified version of a Single Burning Item (SBI) test. Several experiments were conducted

The increasing demand for efficient neural network (NN) inference on edge devices has driven the need for hardware-level optimizations that balance computational accuracy with energy and area efficiency. This thesis explores the design and implementation of a dynamic approximate multiplier capable of mixed-precision inference, focusing on floating-point (FP) formats. Using a logarithmic-approximat

The accumulation of amyloid-β42 fibrils is a hallmark in patients with Alzheimer's disease. The small heat-chock protein αB-crystallin is known to co-exist with amyloid-β42 fibrils and prevent amyloid fibril formation. Amyloid-β42 fibrils arise and expand through different mechanisms of nucleation, however the targeted mechanism by αB-crystallin is yet to be determined. The aim of this project

Ideellt engagemang utgör en central del av det svenska förenings- och studentlivet, där många studenter lägger betydande tid och energi på oavlönat arbete vid sidan av sina studier. Trots avsaknaden av ekonomisk ersättning fortsätter detta engagemang att vara både omfattande och långvarigt, vilket väcker frågor om vilka faktorer som driver studenter att engagera sig och vad som gör att engagemangeVoluntary engagement is a central aspect of Swedish student life, where many students invest significant time and energy in unpaid work alongside their studies. Despite the absence of financial compensation, such engagement remains both extensive and long-lasting. We aim to answer questions such as, what motivates students to participate and what factors contribute to sustaining their involvement

Håldäckselement i betong är ett vanligt förekommande byggelement i Nordeuropa. Det är materialeffektiva element som tillverkas i fabrik med förspänd armering i underkant och ihåliga kanaler centrerat i tvärsnittet. Deras utformning och låga egenvikt bidrar till att möjliggöra långa spännvidder och flexibla planlösningar. Metoden för statisk dimensionering och lastkapaciteter finns dokumenterat och

Byggsektorn står för en betydande andel av klimatutsläppen, vilket gör att både Boverket och EU har föreslagit nya förordningar och regler för mer hållbara alternativ gällande byggnadsmaterial. Där biobaserade byggnadsmaterial kan anses som ett alternativ jämfört med konventionella material. Dessa material, såsom träfiber- och linfiberisolering har potential att minska klimatpåverkan genom att lagThe construction sector accounts for a significant share of greenhouse gas emissions, which has led Boverket and the EU to propose new regulations and guidelines for more sustainable building materials. Biobased construction materials are considered a viable alternative to conventional materials. These materials, such as wood- and flax fibre insulation have the potential to reduce climate impa

This study aims to investigate how social media trends affect international trade through a study on the relationship between the global matcha tea trend and Japanese green tea exports. The study is performed in two steps, due to limitations in social media data access. Firstly, a time-series regression is used to analyse the relationship between global TikTok views and Google search intensity for

Many insects have a behavioral need for the rapid detection of small moving visual targets. In dragonflies and flies, Small Target Motion Detector (STMD) neurons have been found to fill this function, but observations in Hymenopterans raise questions of whether similar neurons are present. In high order variants of these neurons, predictive response gain modulation thought to be driven by dendriti

This thesis examines exchange-rate pass-through (ERPT) to food inflation in Ghana with a focus on domestic transmission channels. Using monthly data, it estimates dynamic reduced-form equations for food inflation and for a set of producer,logistics, transport, and energy-related cost measures. The results show that exchange-rate depreciation passes through meaningfully to food inflation over sever

This thesis presents a scoping review of academic literature on the intersection of religion, spirituality, and Indigenous worldviews with climate change adaptation. While adaptation research has traditionally emphasised technical, institutional, and financial dimensions, the cultural and spiritual dimensions shaping community responses remain underexplored. To address this gap, the review systema

Increasing numbers of species face long-term population declines as a consequence of human activities, and these pressures are expected to intensify under a changing and warming climate. Ground-nesting birds in agricultural landscapes are particularly vulnerable, including the Montagu’s harrier (Circus pygargus), which has declined across Europe due to intensive modern agriculture combined with th

Detailed atomic structures are key to understand and evaluate catalytic activity, ligand binding affinities and many other properties. Neutron crystallography is a popular method for deriving structures of proteins. Unfortunately, the experimental data is typically not enough to settle the exact position of all atoms. Therefore, empirical restraints are employed to ensure that the final structures

This thesis evaluates the ability of three hand-calculation models for estimating overpressure from hydrogen vapour cloud explosions. The models were the TNT, TNO and OHVE models. The aim was to assess their performance in realistic release environments and identify their strengths and limitations. Model predictions were validated against experimental data from three experimental setups: a refuell

Kanarieöarna, en ögrupp i Atlanten som tillhör Spanien och bildades för cirka 25 miljoner år sedan, har en komplex geologisk historia präglad av intensiv magmatisk aktivitet från en underliggande så kallad hotspot. Under hotspoten har extraordinärt varmt mantelmaterial transporterats upp till basen av litosfären som delvis har smält upp. Teneriffa, en av de mest välkända öarna i ögruppen, formadesThe Canary Islands, an archipelago in the Atlantic Ocean belonging to Spain and formed about 25 million years ago, have a complex geological history characterized by intense magmatic activity from an underlying so-called hotspot. Under the hotspot, extraordinarily hot mantle material has been transported up to the base of the lithosphere, which has partially been melted. Tenerife, is one of the be

Nepal ligger i ett av världens mest jordbävningsutsatta områden, och jordbävningen i Gorkha 2015 visade tydligt hur sårbara murverksbyggnader utan ingenjörsmässig dimensionering kan vara. I återuppbyggnadsarbetet har interlocking Compressed Sta- bilised Earth Blocks (CSEB) lyfts fram som ett möjligt alternativ till traditionellt murverk av bränt lertegel. Detta eftersom systemet både kan vara mer Nepal is located in one of the most seismically active regions in the world, and the 2015 Gorkha earthquake clearly demonstrated the vulnerability of non-engineered masonry buildings. In the reconstruction efforts following the earthquake, interlocking Com- pressed Stabilised Earth Blocks (CSEB) have been highlighted as a potentially more seismically robust and at the same time more sustainable al

This thesis conducts a semiotic study of British colonial stamps produced between 1890 and 1960. The main focus is the stamp's message and ideology, understood within the theoretical framework of Roland Barthes and complemented with postcolonial theory by Anne Kaplan and John MacKenzie. The study concludes that two main mythologies can be constructed by analysing the samples, one regarding the
