The European green toad (Bufotes viridis) population in Sweden has faced a significant decline, attributed to habitat degradation, reduced genetic diversity, and the negative impacts of climate change. In response, the Swedish government has implemented protection and conservation strategies. As part of these efforts, Nordens Ark has been involved in rearing captured individuals and reintroducing
Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies. In order to examine the impact of soil conditions on bryophyte species com
Browning - increased water colour of freshwater, caused by rising dissolved organic matter and iron concentrations - has been widely reported and studied during the past 30 years. Browning has affected a wide range of organisms in aquatic ecosystems, however little attention has been given to macroinvertebrates in streams and especially regarding iron concentration. In this study, I include the ef
Resilience is a contemporary ‘hot topic’ in aviation - as well as in many other safety critical industries. The need for understanding resilience has been recognised since it has been noted that serious incidents and accidents are often related to very complex and unexpected situations and failures that cannot be managed with compliance, or which are not covered by existing procedures or checklist
This thesis explores the works and personas of Sylvia Plath and Taylor Swift and analyses the popular conflations of their real lives and their works. Jon Helt Haarder’s theory of biographical performativity is introduced to analyse the threshold aesthetics between reality and art and investigate the feedback loops between oeuvres andlives as well as the interpretation of these in the public spher
In this study the three-factor model of Fama and French (1992; 1993) is evaluated on portfolios of Swedish stocks. Both a cross-section and time series approach are used to evaluate the model. The results show that beta, size, and book-to-market are significant variables in explaining excess returns of Swedish stock portfolios. The three-factor model can explain variations in stock returns on the
This study investigates the relationship between ESG factors and corporate financial performance (CFP) by using data from listed companies in the European market and Thomson Reuters’ ESG scores. The analysis reveals a complex picture, with mixed results for different ESG components. While the environmental component shows no significant association with return on assets (ROA), the overall ESG sco
In jawed vertebrates, the initiation of an adaptive immune response against a novel pathogen relies on antigen presentation, the process whereby the organism’s cells present pathogen-derived peptides to T cells, which recognise the foreign material and elicit subsequent action. The cell surface proteins responsible for antigen presentation are encoded within a region of the genome known as the maj
1. Migratory species are particularly sensitive to climate change and face inadequate protection across their range. However, the behaviour of species and individual spatiotemporal variation in habitat use during their non-breeding periods are comparatively less well understood than breeding and migratory periods. 2. I combined five years’ worth of GPS tracking data on juvenile Caspian terns wit
Development in sequencing technologies has made the analyses of genetic material much more accessible. Processing sequenced data for an accurate analysis comes with its challenges, especially with the studies in microbial in clinical in vivo samples where difficulties in the collection of these samples for sequencing could lower the quality and contamination from the human host which might affect
Fully implicit Runge-Kutta methods play an important role in the numerical integration of stiff differential equations. Radau IIA is the most commonly used fully implicit method due to its good theoretical performance. However, Radau IA and Lobatto IIIC might also be suitable for different problems. These three methods are constructed using simplified order conditions that ensures specific integra
Many former colonial powers have been reluctant to return cultural heritages acquired during colonial context for various reasons. The Netherlands is a unique example where it is willing to repatriate cultural heritages acquired in colonial context back to its original country unconditionally. This thesis examines the causes of the Netherlands willingness to repatriate cultural heritages by using
This thesis investigates the motives and partner selection processes in environmental alliances through a multiple case-study approach. Utilizing semi-structured interviews with senior managers deeply involved in these alliances. Drawing from the resource-based view and network theory, it explores diverse dimensions of motivation, later integrating institutional theory to account for unexplained v
The purpose of this study was to examine how INGOs in Sri Lanka work to increase social capital and trust between two specific ethnic groups- the Tamils and Sinhala. The study uses a qualitative approach, where this dissertation draws on Michel Foucault’s Discourse Analysis with the concepts of power/knowledge and governmentality as central themes in the empirical data. The empirical data is provi
Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficienc
The increase of feminist foreign policy (FFP) declarations globally has provoked a vigilant scrutiny of these policies, especially their alignment with transformative, postcolonial, and intersectional feminisms. Contributing to existing scholarship on FFPs, this thesis explores the establishment of FFP in Germany from consultation process to final guidelines. Using a multidimensional Critical Disc
I och med klimatförändringarna kommer våra samhällen att drabbas av större regn vilket kommer att öka kraven på de redan överbelastade spillvatten- och dagvattensystemen. Enligt dagens deterministiska planeringspraxis dimensioneras nya lösningar till att ta hand om den ökande mängden vatten vilket skapar en accelererande kostnadsökning för städerna. Samtidigt saknas oftast ett helhetsgrepp för helClimate change and urbanization is a threat for existing stormwater networks. Many stormwater networks are designed after historical rain data that will fail to predict future events due to large changes in rainfall patterns caused by climate change and urbanization. This may lead to insufficiencies in the hydraulic capacity of stormwater networks and an increased probability of stormwater network
There is always talk of climate change in the future, but climate change is already present in all its facets. Intense droughts, water scarcity, severe fires, rising sea levels, floods, melting polar ice, catastrophic storms, and the decline of biodiversity are already visible. The city of Munich is no exception, as problems like heat, drought, and heavy rain increasingly have to be dealt with. We
