In a growing global corporate bond market, insights and understanding of the markets pricing mechanisms becomes increasingly important to investors. While previous research on credit risk has mainly focused on the American bond market, European bonds remain rather unexplored in academia. In this article, we investigate the explanatory power of a family of credit risk models - called structural modThis thesis empirically tests the explanatory power of structural models on the European corporate bond market. Using new evaluation methods, including LASSO and gradient boosting regression, we can provide an in-depth assessment of the models’ shortcomings. With these tools we show that the structural models tend to systematically overstate or understate the spread due to an oversensitivity to le

One of the characteristic features of Indian society is its complex caste system which ranks people into hereditary groups. Most importantly, the foundation of caste association was based on the occupation of each group. And the lowest group within this system have historically been excluded and exploited due to their assigned caste-based occupations. Despite implementing affirmative action polici

Different types of data streams, time series, are generated in systems and collected in information bases all over the world. One may have data streams of temperatures, air pollution, share prices, traffic demand for networks or strength of the emitted radiation from a power plant. There are different statistical tools to analyse these data streams. An interesting tool to evaluate a data stream is

Nanostructures are found everywhere in our environment, of either natural oranthropogenic origin. Volcanoes emit them, breakdown of plastic releases them, andthey are even produced in candlelight. Designed nanostructures are used in sunscreen,food products, electronics and many more readily available products. Still, there are alot of things we do not know about their behavior. To call them miniscThis thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. Similarly, the nanomaterial sources vary from spherical titanium dioxide, gold, and polystyrene nanoparticles to novel nanowires of gallium arsenide

The importance of long-term historical information derived from paleoecological studies has long been recognized as a fundamental aspect of effective conservation. However, there remains some uncertainty regarding the extent to which paleoecology can inform on specific issues of high conservation priority, at the scale for which conservation policy decisions often take place. Here we review to wha

Syftet med den här uppsatsen är att argumentera för en individuell föräldraförsäkring. Den svenska föräldraförsäkringen studeras utifrån ett rättighetsperspektiv, något som tidigare har saknats. Föräldraförsäkringen är idag en grupprättighet och stor del av min teori har därför kretsat kring grupprättigheter och individuella rättigheter. I analysen av förarbetena till föräldraförsäkringen blir det

Globally 884 million people depend on unsafe drinking water, of which 159 million depend on untreated surface water (WHO, 2017). In Tanzania 44% of the popula- tion lack access to safe drinking water (WaterAid, 2017). Women and children in the small city of Chonyonyo, in Karagwe district are walking several hours a day for contaminated drinking water. According to a study, carried out in TanzaniIn Chonyonyo, a village in north-west Tanzania, the majority of the population have no access to the groundwater beneath them. Every day, women and children walk several hours to a hole shared with animals, to collect contaminated drinking water for their families’ domestic needs. This report shows that the groundwater resources in the area are sufficient to supply the people of Chonyonyo with fre

Ett projekt inom ArtCollab Generativ AI håller snabbt på att förändra hur kreativitet skapas, värderas och förstås i samhället. Samtidigt som tekniken effektiviserar och breddar tillgången till kreativa verktyg, riskerar den att förskjuta kreativitet från en mänsklig erfarenhet till en optimerad och delvis ogenomskinlig process styrd av algoritmer. När beslut, uttryck och urval filtreras genom sys
