The background for this thesis is that access to sustainable electricity is part of the United Nations’ Sustainable Development Goals for 2030. In Sub- Saharan Africa, approximately 570 million people lacked access to electricity in 2022. To expand access in rural areas, solar home systems and other off-grid solar products offer affordable and accessible solutions. However, as these systems reach

Bakgrund: Kulturhistoriska byggnader har ett särskilt historiskt, estetiskt eller socialt värde och skyddas av regler som begränsar förändringar. Med rätt byggnadsvård och tekiska lösningar kan bevarande kombineras med energieffektiviseringar. Även om bevarande ofta innebär högre initiala kostnader, kan det ge långsiktiga värden både kulturellt och ekonomiskt. Syfte: Syftet är ett undersöka hur kThroughout history, construction practices have reflected the materials, knowledge, and economic resources available at the time. These historical characteristics are now seen as cultural assets worth preserving. However, older buildings often fail to meet modern standards, necessitating significant interventions to comply with today’s regulations. This thesis explores the challenges and opportun

In recent years, discussions regarding problematic school absenteeism have increased in research and media. The Swedish National Agency for Education (Skolverket) observed an increase in both valid and invalid absences among students attending compulsory school in 2023, compared to previous years. Using Michael Lipsky's theory of street-level bureaucrats, which encompasses alienation, discreti

Disasters such as COVID-19 and the Russia–Ukraine war are drawing attention to the provisioning of food during crises. The main concern has been quickly establishing a stable food supply. However, climate change and public health concerns are shifting attention to the critical gap in identifying the minimal considerations that would adequately address ecological disaster food provisioning. A meta-

Introduction. This article presents the first results from the LibPrepare research project, which explores how the democratic mission of public libraries is understood, imagined and potentially compromised in times of crisis and war rhetoric. The aim is to gain knowledge of the mechanisms, motives and potential implications of enrolling libraries in Swedish national security policy.Method. A themaIntroduction.

The transition to the Nordic Bronze Age included new technological innovations, social institutions and sociopolitical structures pushed by extensive long-distance exchange of metals and other exotica. However, traditional views often oversimplify this as a simple two-way trade system, failing to adequately explain the complex interactions in and between the regions like Scandinavia in which the s

Learning a language is a creative process. It involves novelty and imagination. While curiosity can be highly beneficial, research is limited. Studies so far conducted have explored epistemic curiosity as a trait-like disposition. In contrast, the current study focuses on perceptual curiosity (PC). PC is a situational response evoked by novelty, complexity and ambiguities in sensory stimulation. P

Deklinationsdata från sedimentära borrkärnor från sjöarna Kälksjön, Gyltigesjön, Byestadsjön, Mötterudstjärnet, Furskogstjärnet, Frängsjön och Särsjön visar västlig riktning i den övre delen. Denna västliga riktning följer inte paleomagnetiska modeller och är missvisande. Med hjälp av Microsoft Excel har dessa missvisningar korrigerats och använts för att skapa en svensk version av FENNOSTACK, kalDeclination data from cores from swedish lake sediments show a westward declination in the upper part of most cores. This does not align with paleomagnetic models and is therefore considered false. Using Microsoft Excel these false values have been corrected and used in a swedish version of FENNOSTACK called SWESTACK. SWESTACK gives a mean value with 95\% confidence of the declination over the per

This paper discusses how archaeologists might investigate issues of poverty by focusing on poorhouses. The poor and deprived are rarely prominent objects in archaeological research, probably because archaeologists find it difficult to relate to a concept such as poverty. At the same time, there is material culture that can be clearly linked to poverty. One such materiality is poorhouses. While the

This thesis investigates the adoption implications of AI-driven Clinical Decision Support Systems (AI-CDSS) for early breast cancer detection within healthcare workflows. Despite advancements in AI technology and its demonstrated potential to enhance diagnostic accuracy and efficiency, real-world adoption remains limited due to technical, organisational, and ethical challenges. Using a qualitative

This thesis investigates how algorithmically driven features of social media platforms, specifi cally personalized recommendations, infinite scroll, auto-play and push notifications affect university students’ emotional states and academic performance. Drawing on the Stimulus - Organism - Response (SOR) framework, the study explores how these features act as digital stimuli that provoke cognitive

With ongoing strains and disparities in the healthcare system, Generative AI applications are increasingly viewed as promising tools to alleviate pressure in this sector. Trust is seen as a critical enabler for the integration of GenAI tools. However, this area remains largely unexplored, with limited research examining user-perceived trust. This study addresses this gap by adopting a qualitative

As organisations increasingly seek to leverage data for artificial intelligence (AI) analytical use-cases, one of the main challenges towards value realisation is effective use of data governance. Existing research on the topic of data governance focuses on technical and structural aspects of data governance, while this thesis identifies human-centred organisational success factors for data govern

Digital spelifiering har blivit ett allt vanligare inslag i rekryteringsprocesser. Trots teknikens framväxt är kunskapen begränsad kring hur kandidater och rekryterare uppfattar rättvisa och transparens i digitala spelifierade urvalsmoment. Denna studie syftar till att undersöka hur dessa aspekter hanteras, kommuniceras och upplevs, ur både ett företags- och kandidatperspektiv. Vid datainsamling h

This thesis examines digital nomads in Portugal, a popular destination for location-independent digital workers, through multi-sited ethnographic fieldwork conducted over winters of 2024 and 2025. The research examines digital nomads' motivations and challenges of the pursuit of freedom and mobility, loneliness and social isolation, their role in the socioeconomic impacts of gentrification, an

This qualitative study aimed to explore the perceptions of social workers in various professional roles—social secretaries, counselors, and family therapists, regarding sibling abuse, and to examine whether their perspectives differ. The study also sought to investigate the potential consequences associated with a normalized view of sibling abuse for the children involved. Semi-structured intervie

Sibling violence is an often overlooked form of domestic violence, despite research suggesting it is one of the most common types of violence experienced by children. This study aims to explore the challenges faced by family therapists within Swedish social services in identifying and addressing sibling violence, how these challenges affect their professional discretion, and what consequences sibl

A novel metaheuristic algorithm called the reptile search algorithm (RSA) was introduced in conjunction with artificial neural fuzzy inference system (ANFIS) for the estimation of standardized precipitation evapotranspiration index (SPEI). The model was tested in three different climates: arid and super-cold, semi-arid and cold, and semi-arid and moderate climate across Iran by combining meteorolo
