The Garrison Church in Potsdam : Reconstruction, Reconciliation, and Reflection
No full textThis thesis investigates the reconstruction of the Garrison Church (Garnisonkirche) in Potsdam, a historically burdened site intricately tied to Prussian militarism and its symbolic appropriation by the Nazi regime. Severely damaged during World War II and demolished by the German Democratic Republic (GDR), the church’s contemporary rebuilding has sparked significant political and cultural controversy, raising urgent questions about memory, historical responsibility, and the instrumentalization of heritage in post-reunification Germany. The central research question examines how the legacy of militarism and nationalism is negotiated in the reconstruction process, and to what extent the site can be transformed into a space of reconciliation and critical historical reflection, particularly in the face of its appropriation by far-right political actors. Drawing on memory studies, critical heritage discourse, and German traditions of Erinnerungskultur and Vergangenheitsbewältigung, the study combines historical and narrative analysis within a single-case study design. Primary sources include institutional publications, exhibition materials, public discourse, and archived versions of the Garrison Church Foundation’s website. The findings demonstrate a pronounced tension between the church’s stated aims of remembrance and reconciliation and its institutional narrative. While early phases of the project invoked a moral commitment to confronting the past, more recent developments reveal a shift toward depoliticized cultural branding and touristic appeal. The increasing marginalization of critical voices, the removal of foundational documents, and the strategic reframing of public messaging suggest an erosion of transparency. Furthermore, the project’s symbolic ambiguity has created openings for nationalist reinterpretation, reinforcing rather than confronting the very ideologies it claims to transcend. By situating the Garrison Church reconstruction within broader debates on memory politics and contested heritage, this thesis argues that the site embodies both the potential and the fragility of critical remembrance in contemporary Germany
Dubbel väsentlighetsanalyssom strategiskt verktyg : En studie om företags legitimitetsskapandegenom hållbarhetsrapportering
No full textEU:s nya direktiv för hållbarhetsrapportering Corparate Sustainability Reporting Directive (CSRD) har gjort det tydligare och mer krävande för företag att redovisa sitt hållbarhetsarbete. En viktig komponent av direktivet är den dubbla väsentlighetsanalysen (DVA), som kräver att företag måste bedöma hur hållbarhetsfrågor påverkar deras verksamhet finansiellt och hur dessa påverkar omvärlden. Syftet med denna kandidatuppsats är att undersöka hur svenska företag använder sig av DVA med ett särskilt fokus på dess roll för att skapa legitimitet gentemot intressenter och samhälle. Genom att använda teoretiska ramverk som legitimitetsteori och signaleringsteori undersökte vi om DVA används som ett tillvägagångssätt för att enbart uppfylla regulatoriska krav eller om det också fyller en strategisk funktion. Metodmässigt är studien kvalitativ och ämnar till att analysera 17 olika hållbarhetsrapporter från både statligt och privat ägda företag. För att kunna analysera den stora mängden text och data har en mognadsmatris utvecklad av Cöster et al. (2020) använts. Mognadsmatrisen omfattar sex kategorier för att bedöma hur företag arbetar med att “göra rätt saker” och “göra rätt saker på rätt sätt” inom sina hållbarhetsrapporter. Studiens resultat visar stora variationer i hur företag väljer att använda och kommunicera DVA. Företag med högre mognadsnivåer tenderar att integrera DVA i hela sin verksamhet, redovisa tydliga kopplingar till intressenternas behov samt använda sig av externa ramverk som exempelvis FN:planetära gränser eller Parisavtalet. Studiens resultat visar att det signalerar en pragmatisk eller moralisk legitimitet. Företag med en lägre mognadsnivå visade enligt studien ofta en kognitiv legitimitet vilket innebär att DVA används för att uppfylla samhällets förväntade normer utan någon strategisk förankring. Studien visar att DVA har potential att fungera som ett strategiskt verktyg i hållbarhetsarbete och bidrar till en ökad förståelse för hur DVA kan användas för en legitimitetsskapande kommunikation i en reglerad och komplex omvärld.
Alternative small house building
No full textThis thesis examines the possibility of transferring certain construction tasks in the newproduction of single-family homes with private ownership to the customer. Thebackground of the study is a growing need to streamline the construction process andreduce building costs, while demand for single-family housing remains high in Sweden.Based on current laws and regulations, the study analyses which construction taskscan be excluded without affecting the functionality of the building or the ability to obtainfinal approval. The thesis is based on a combination of qualitative and quantitativemethods. Semi-structured interviews were conducted with professionals from theconstruction industry. In addition, a comparative study of an existing small houseproject was carried out, where the effects of handing over selected tasks to thecustomer were analysed in relation to construction time and production cost. Therevised schedule showed a time reduction of 13,2%, and the cost estimate indicated adecrease in production costs by 14,8%. The interviews also show that the success ofthe concept depends on clear communication, legal clarity, and identifying the righttarget group. The results show that several interior tasks, such as painting, flooring,and parts of the kitchen installation, can be transferred to the customer withoutpreventing final approval. The conclusion is that this type of concept can serve as acomplement in the new production of single-family homes, if it is designed withconsideration for regulations, market conditions, and the customer's ability to completethe remaining work
Leveraging Large Language Models for Project Generation in Category Management
No full textThe continuous advancements made on Large Language Models (LLMs) present promising avenues for applications within category management. This thesis aims to investigate the application of LLMs for project generation within category management. To this purpose a project generation system is proposed based on the Purchasing Chessboard framework. Several methods are evaluated for the system, which includes Few-shot learning, Chain-of-Thought prompting, Prompt Chaining, and External Context Integration. Additionally, further investigation is made into the use of LLM-based evaluation methods, and an analysis is made of the correlation with human evaluation. The results show that LLMs can effectively generate relevant projects, with the combination of Few-shot learning and Chain-of-Thought prompting producing the best results according to human evaluation. The LLM-based evaluation shows a low to moderate correlation with human evaluation, suggesting it has limited utility. The results indicate the potential of leveraging LLMs for project generation in category management and highlight the need for further research into the use of more advanced architectures as well as the use of more category-specific data
Updated model-independent measurement of the strong-phase differences between D0 and D¯0 → K0S/Lπ+π− decays
No full textThe strong-phase differences between D0→K0S(L)π+π− and ¯D0→K0S(L)π+π− decays are one of the most important inputs in measuring the CP violating angle γ via B− → DK− decays. They also play a key role in studies of charm mixing and indirect CP violation. In this paper, the strong-phase differences are determined in a model-independent way with quantum-correlated D0-¯D0 decays from 7.93 fb−1 of e+e− annihilation data at √s = 3.773 GeV by the BESIII experiment. These results are the most precise to date and are expected to significantly reduce associated uncertainties in determining the CP violating angle γ and related charm mixing parameters.For complete list of authors see http://dx.doi.org/10.1007/JHEP06(2025)086</p
The assault on Norrskensflamman, the memory of a dark heritage
No full textAttentatet mot Norrskensflamman 1940 i Luleå, där svenska militärer sprängde en byggnad och fem omkom, lämnade efter sig ett mörkt kulturarv och ett minne av en tragedi som har överlevt fram till idag. Även om händelsen av många anses vara det största attentatet inom Sveriges gränser i modern tid, har historiskt sett väldigt lite forskning, skrivande eller tal om det ägt rum. Många som var involverade under den tiden har upplevt att det har varit ganska tyst om vad som hände och att det generellt har varit svårt att prata om det. Kommunisterna i Norrbotten blev en sårbar grupp i Sverige under andra världskriget, som förföljdes, censurerades och sattes i interneringsläger. Attentatet som genomfördes mot den största svenska kommunistiska tidningen, Norrskensflamman, var kulmen av förföljelsen. Uppsatsen är en modern konfliktarkeologisk studie som fokuserar på det materiella kulturarvet efter händelsen. Studien problematiserar monumentets funktion som restes för offren sextio år efter händelsen och den alternativa materiella kultur som skapades efter attacken, från ett teoretiskt perspektiv av materialitet, minne och mörkt kulturarv. Genom att studera den materiella kulturens funktion har studien visat att den kan öppna dörrar för nya tolkningar av händelsen, vilket kan underlätta bearbetningen av minnet av ett mörkt kulturarv bland allmänheten.The assault on Norrskensflamman in 1940 in Luleå, where Swedish soldiers blew up a building and five died, left behind a dark cultural legacy and a memory of a tragedy that has survived to this day. Although the event is considered by many to be the largest assault within Sweden's borders in modern times, historically very little has been researched, written and spoken about it. Many who were involved during that time period have experienced that there has been quite silence about what happened and that it has generally been difficult to talk about it. The communists in Norrbotten became a vulnerable group in Sweden during the Second World War, who were persecuted, censored and locked in internment camps. The assault carried out against the largest Swedish communists' newspaper, Norrskensflamman, was the culmination of the persecution. The essay is a modern conflict archaeological study that focuses on the material cultural heritage after the event. The study problematizes the function of the monument erected for the victims sixty years after the event and the alternative material culture created after the attack, from a theoretical point of view of materiality, memory and dark cultural heritage. By studying the function of material culture, the study has shown that it can open doors for new interpretations of the event, which can facilitate the processing of the memory of a dark cultural heritage among the public
Sustainable Carbon Materials from Biomass: Pyrolysis and Laser-Induced Carbonisation for Energy Storage Applications
No full textThe transition to a sustainable society requires not only advances in renewable energy technologies but also the development of environmentally responsible materials from renewable sources. A circular economy depends on the effective use of biomass and biowaste—not only for energy production, but also for functional materials and fine chemicals. Replacing fossil-based carbon with renewable feedstocks reduces environmental impact, decreases reliance on imported resources, and strengthens local economies. It also improves resilience by minimising dependence on critical raw materials from geopolitically sensitive regions. Carbon-based materials are central to energy storage systems such as lithium-ion batteries and supercapacitors, yet their current production often relies on mined graphite and fossil-derived carbon, both linked to ecological and economic concerns. This thesis investigates the sustainable synthesis of hard carbon and graphene-like materials from renewable biomass and industrial biowaste, focusing on their use in electrochemical energy storage. Alongside conventional pyrolysis, a novel method—laser-induced carbonisation—is explored as a fast, localised, and energy-efficient alternative that eliminates the need for inert gases and prolonged heating. Biomass precursors such as tannins, kraft lignin, brewer’s spent grain, nanocellulose–polypyrrole composites, and phenolated organosolv lignin were used. The resulting carbons were extensively characterised and tested in supercapacitors and lithium-ion batteries, showing promising performance. Beyond material development, the thesis emphasises the socioeconomic benefits of integrating renewable carbon sources into energy storage value chains. This shift enhances climate sustainability, economic self-reliance, and energy security. Overall, the findings demonstrate that bio-based carbon materials offer viable, high-performance alternatives to conventional sources, supporting a more circular and sustainable energy future
Reprogramming LLMs for Multimodal Time Series Forecasting
No full textHuman pose prediction plays a vital role in applications such as human-computer interaction, robot control, and intelligent surveillance. Traditional methods primarily rely on single-modal inputs such as skeletal keypoints or RGB video, which often fall short in comprehensively understanding complex human motions. In this thesis, we propose a novel multimodal Time-LLM framework that fuses structured skeletal data (in CSV format) with monocular video information for future pose prediction. Building upon the Time-LLM architecture, we introduce a visual patch reprogramming module that maps spatiotemporal visual features into discrete embedding representations understandable by large language models (LLMs). These visual embeddings are concatenated with prompt tokens and skeletal time-series embeddings to form a unified input sequence for the LLM, thereby enabling cross-modal joint reasoning. Our method fully leverages the strengths of pre-trained LLMs in temporal modeling and generalization, demonstrating powerful representational and reasoning capabilities on nonlinguistic sequence prediction tasks—without the need for fine-tuning. Finally, we propose exploring the framework’s potential applications in broader domains such as self-driving, multimodal biometrics, security surveillance, and abnormal behavior detection as part of future work. These directions remain conceptual and are not experimentally validated in this thesis
Temperature does not affect the Alinity m Multi-Collect Specimen test tubes for analysis of Chlamydia trachomatis and Neisseria gonorrhoeae
No full textBackground: Sexually transmitted infections (STI) are a global problem that in a worst-case scenario can cause infertility. The need for urgent testing of the most common STIs is growing larger by the year. At the time of the study in Västernorrland, Sweden, large parts of the population live in rural areas and have long distances to healthcare centres. Homebased self-sampling existed for urine and vaginal swabs, but it was unknown if the Alinity m Multi-Collect Specimen (MCS) test tubes could handle the varied temperatures in the county. Objective: To test if the MCS test tubes used for PCR analysis of Chlamydia trachomatis and Neisseria gonorrhoeae could withstand different temperatures. Material and methods: A total of 40 pooled patient samples were tested and analysed at day 0, 1, 2 and 3 with the PCR instrument Alinity m STI Assay. Three different temperature intervals were stimulated at the lab, the temperatures were Warm, Around Zero and Cold, above or under what the manufacturer specified the tubes could handle. Results: The samples were stable throughout the days; most had a standard deviation of less than 0,50 cycle number (CN) with only two samples having a CN over one. Chlamydia varied the most in the Cold temperature interval while gonorrhoeae varied most at the Warm temperature interval, but both had a mean standard deviation of 0,38 and 0,32 CN respectively and thus barely any change. Conclusion: This study showed that the MCS test tubes can keep the samples stable despite the variation in temperature
PET imaging of platelet derived growth factor receptor β in lung fibrosis
No full textBackground: Lung diseases such as idiopathic pulmonary fibrosis and acute respiratory distress syndrome (ARDS) are associated with significant morbidity and mortality, with limited treatment options. Platelet-derived growth factor receptor beta (PDGFRβ) signaling pathway is a key driver of fibrogenesis in different organs. In the lungs, pericytes have a high PDGFRβ expression, and their role as immune regulators and progenitors of myofibroblasts is increasingly recognized. Non-invasive techniques to assess active lung tissue remodeling are needed to improve disease monitoring and treatment evaluation. This study aimed to evaluate [18F]TZ-Z09591, targeting PDGFRβ, for imaging pulmonary injuries in human biopsies, and in vivo in animal models of lung injury. Results: [18F]TZ-Z09591 demonstrated high and specific binding to PDGFRβ-expressing cells. Autoradiography confirmed tracer uptake in lung injuries, including fibrotic foci, from human, rat, and pig lung tissues. In vivo positron emission tomography (PET) imaging of bleomycin-induced lung fibrosis in rats and an ARDS pig model showed significantly increased uptake in diseased lung segments compared to controls, especially in pulmonary injuries with collagen deposition, despite moderate background uptake. Conclusions: This study demonstrated that [18F]TZ-Z09591 can assess PDGFRβ expression in pulmonary injuries, supporting its potential for non-invasive assessment of lung tissue remodeling. PET imaging targeting PDGFRβ could improve disease monitoring, and provide new insights into pulmonary fibrosis progression
