The Shallow Neural Network (SNN) is one of the most basic forms of machine learning models. It has a high theoretical representational capacity, but this is often not realized in practice, in part due to overfitting. This thesis proposes a new regularization method and compares it against existing techniques across a range of tasks using SNNs. The proposed method, norm-preserving regularization (N
This study examines how social entrepreneurs reason through potential value conflicts between social and commercial considerations, a process that has received little empirical attention at the individual level. We conducted scenario-based, semi-structured interviews with eight social entrepreneurs leading established social enterprises in Sweden, drawing on think-aloud and retrospective verba
Precise determination of the time of simultaneous incidence of laser pump and X-ray probe pulses is essential for ultrafast X-ray diffraction experiments. This work investigates the use of diffuse scattering from the phase-change material Ge2Sb2Te5(GST) as a timing tool for pump-probe measurements at the FemtoMAX beamline at MAX IV Laboratory. A complete data analysis pipeline was developed to pr
Denna studie undersöker hur unga vuxna i åldern 18-20 år tolkar och uppfattar Försvarsmaktens kommunikation på TikTok, med särskilt fokus på govtainment, plattformsspecifika uttrycksformer och trovärdighet. Studien tar sin utgångspunkt i spänningen mellan anpassning till TikToks plattformslogik och kultur och de förväntningar på saklighet, seriositet och trovärdighet som ofta omger myndighetskommuThis study explores how young adults aged 18-20 interpret and perceive the Swedish Armed Forces’ communication on TikTok, focusing particularly on govtainment, platform-specific expressions and credibility. The study is centered on the tension between adapting to TikTok’s platform logic and culture and the expectations of objectivity, seriousness and credibility that typically surround government
Söderåsens nationalpark är ett populärt område för friluftsliv på grund av den vidsträckta bokskogen. Bokskogen har också ett stort vetenskapligt intresse på grund av dess dynamiska historia under de senaste seklerna. Enligt Rundgren et al. (2025) var boken väletablerad fram till mitten av 1700-talet då dess utbredning minskade för att sedan börja öka igen under mitten av 1800-talet. Detta baseradSöderåsen National Park is a popular recreational area due to its extensive beech forest. The beech forest is also of great scientific interest because of its dynamic history in recent centuries. According to Rundgren et al. (2025), the beech was well established until the mid-18th century when its abundance decreased markedly, followed by an expansion from the mid-19th century. It is based on pal
With novel techniques like single-cell RNA sequencing (scRNA-seq) we can look inside single cells in great detail and measure their individual gene activity by counting the mRNA molecules of the cells. In order to model cell differentiation one would naturally turn to longitudinal data of single cells. However, snapshot datasets is the basis of single cell studies due to the way the datasets are c
Older adults have throughout history played an important role in the shaping of society. Through work and life experience, they have helped pass along valuable knowledge and hence paved the way for future generations’ possibilities of building and creating a way of living and functioning in an ever-changing world. Yet, the aging generations can sometimes be forgotten or marginalised in modern soci
During recent years the interest in visits to the Swedish alpine regions have increased, and many regions have experienced a trend towards a higher number of sport events. An increasing interest in nature tourism can bring positive effects on wellbeing and health as well as increasing knowledge and consideration for the environment. Though, all effects are not positive since nature-based activitie
Game-playing algorithms often face a trade-off between analyzing moves that currently look promising and exploring alternatives whose value is uncertain. AlphaZero-style chess engines combine neural network evaluation with Monte Carlo tree search to selectively explore the game tree. We evaluate a variance-aware modification of the PUCT tree policy on chess puzzles and find that it underperforms s
Colonialism has been a significant influence on the shape of our modern world. Colonialism creates power structures and social systems that continue to inform contemporary institutions and systems of knowledge production. Archaeology has historically been connected to these colonial structures by privileging hegemonic and Eurocentric epistemological research structures. In efforts to acknowledg
This thesis examines the relationship between spatial accessibility, institutional delivery and timely initiation of breastfeeding in Nigeria, Ghana, Tanzania and Zambia. It uses recent DHS data combined with OpenStreetMap data on health facilities and roads to construct spatial accessibility measures, including distance to the nearest health facility, distance to major roads and combined accessib
Single rare-earth ions in crystals are promising systems for quantum information experiments, but detecting the fluorescence from a single ion remains challenging. An open-access fibre Fabry–Pérot microcavity can enhance the ion–light interaction and improve photon collection, but useful operation requires the cavity length to be stabilized at the picometer scale. This thesis studies both passive
Micro- and nanoplastics (MNPs) are widespread environmental pollutants capable of crossing biological barriers. Nanoplastic tyre wear particles (NTWP) are of particular concern because tyre abrasion is a major source of nanoplastic pollution. This study investigated whether NTWP affects monocyte-derived dendritic cell (moDC) activation and subsequent T cell responses, both without antigen and in t
This thesis explores the emotional potential of a naturum in the abandoned Limhamn quarry, reflecting on how nature and built environment can harmonize through architectural intervention, in order to facilitate a space that can envoke different kinds of emotions, whilst still providing form that harmonizes with the surrounding landscape, and functional exhibition spaces for visitors.
This thesis investigates the collected surface assemblage from Shubayqa 3, an unexcavated prehistoric site in the Qa’ Shubayqa region of north-eastern Jordan. It examines what surface-collected lithic material can reveal about chronology, spatial organisation, and repeated activity, while also considering the limitations of a mixed assemblage without secure stratigraphic context. The study combine
Sammanfattning Den här studien undersöker hur tävlings- och spelbaserad gamification påverkar konsumenters köpbeteende på den svenska marknaden, med fokus på två dimensioner: benägenheten att genomföra ett första köp och utvecklingen av kundlojalitet. Trots att gamification har blivit ett allt vanligare marknadsföringsverktyg är forskningsfältet splittrat och kunskapen om hur spelbaserade kampanj
Studien undersöker hur surfkultur används och representeras i platsmarknadsföringen av Varberg i relation till den ökade användningen av lokala kulturer inom platsmarknadsföring. Studiens syfte är att undersöka hur surfkultur omvandlas från en lokal praktik till en strategisk resurs, samt hur omvandlingen påverkar hur destinationen framställs och uppfattas. En kvalitativ fallstudie har genomförts
The purpose of this study is to deepen the understanding of the social worker’s professional role and practice in relation to public debate and politics, with a focus on three distinct themes: The influence of public debate on the professional role and its consequences, Political unawareness and its consequences for the professional role, and the influence of public debate on service users. In ord
This study examined how social workers in Swedish social services described their work with communicative accessibility for children with communication difficulties or children who do not use verbal communication. The study also examined the professional and organizational conditions that affected this work and the consequences that limited communicative accessibility could have for children's
