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

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

Megalencephalic leukoencephalopathy with subcortical cysts (MLC), is a congenital leukodystrophy with childhood onset. It is an extremely rare genetic disorder of the brain that affects less than 1 per 1,000,000 live births. Patients typically present macrocephaly during early childhood and later develop symptoms like decreased motor and cognitive functions, and epileptic seizures, all of which us

On the basis of an article recently authored by the Swedish Minister for Public Administration, the main purpose of this thesis is to examine whether contracting authorities are allowed to refer to ‘Swedish’ standards of animal welfare (whether explicitly or not) when purchasing foodstuffs, without infringing the EU rules on free movement. In making this assessment, the thesis identifies three rec

In this essay, I explore the motifs of bodily destruction and self-mutilation in the first three novels of American author Chuck Palahniuk: Fight Club (1996), Survivor (1999) and Invisible Monsters (1999). These motifs are prevalent throughout the author’s work and are particularly noteworthy in how detailed and graphic the novels are. In analysing the ways in which the characters of these novels

Forest fires in mainland Portugal are becoming more extreme, resulting in increasingly larger burnt areas and tragic human fatalities, as was shown by the 2017 fires. Research shows that there are many natural factors contributing to such fire vulnerability conditions, such as climate, fuel continuity, forest structure, tree species types, amongst others, that are intertwined with anthropic factor

Changed land-use, nitrogen deposition, climate change, and the spread of non-native species have repeatedly been reported as the main drivers of floristic changes in northern Europe. However, the relevance of the geographical scale at which floristic changes are observed, is less studied and understood. Here, I assess the changes in species richness and species composition in the central parts of

In 2022 the Russian war against Ukraine left Germany without imports from their biggest energy supplier, forcing them to find new energy sources. One of the government’s measures was the investment in LNG, which impacts society and the environment. With a critical discourse analysis, this thesis analyzes how the government justifies their choice for LNG and how energy justice is considered within

This study examines the relationship between development aid and trade, specifically focusing on the impact of aid on exports for 14 European donor countries committed to allocating 0.70% of their Gross National Income (GNI) to official development assistance (ODA). The 14 selected countries account for 41.5% of global ODA disbursements. Estimating a structural gravity model using Pseudo Poisson M

The EU's economy is heavily influenced by public procurement, with services, works, and supplies worth approximately €2 trillion being purchased by public authorities annually. While the EU's legal framework allows for electronic means in public procurement, the aim is to achieve full e-procurement to maintain transparency, equal treatment, non-discrimination, and fair competition. However

Purpose: This thesis delves into the dynamic relation between awe and art, specifically focusing on abstract versus representational art within immersive Virtual Reality (VR) environments. Prompted by the expansion of awe research since Keltner and Haidt’s seminal work (2003) and the research gap on art and VR, this study explores whether the level of abstraction in art influences the intensity of

Today, approximately 55% of the total global population lives in urban areas, while in Europe the number is higher than 70%, and both figures are expected to continue growing during the next decades. At the same time, cities are facing an increasing number of challenges, such as sea level rise, increased temperatures, air quality and more extreme weather events. Nature-based Solutions (NbS), altho

The cell transmembrane receptor CD44 is a member of type I transmembrane receptor family that is found on the outer surface of different types of both immune and cancer cells. It is used by the cells to detect as well as to respond on different changes in the near environment. CD44 receptors are involved in a variety of processes such as hematopoiesis, lymphocyte homing, or limb development. The r

Bacterial respiration and biomass growth are important processes for carbon cycling in freshwater ecosystems and bacterial respiration is often quantified from measured O2 concentrations by using a respiratory quotient (RQ=O2 consumed to produce CO2, in moles) of 1. Recent studies have shown, however, that RQs can vary a lot in different aquatic ecosystems (0.5-5), which may lead to an under- or o

Due to COVID-19 and the penetration of OTT services, the cinema industry is suffering from audience loss. With this contextual change, the question of whether the cinema industry will survive is constantly rising. As motivation is known as the driving force for behaviour, this thesis focuses on the audiences who still visit the cinema and explore their motivations for cinema attendance to find wha

Breast cancer is the most common cancer among women and two thirds of all breast cancers are classified as oestrogen receptor positive. ER is a transcription factor that regulates gene expression and promote cell proliferation that is critical in mammary gland development, and its aberrant activity is commonly present in breast cancer. As a nuclear receptor, ER activity could be diverted by eith

The harvest mouse Micromys minutus has, through nest findings, been documented to live in wetlands in tall sedges and grasses in Central Europe. However, there is very little information on the type of habitat this species uses outside of nesting, because this rodent is difficult to capture in ordinary trapping set-ups. In France and Switzerland, the harvest mouse populations have decreased strong
