Syftet med uppsatsen är att empiriskt undersöka ifall det är möjligt att göra en överavkastning, genom att konstruera tre olika utdelningsbaserade handels-strategier. Den första handelsstrategin innebär att de företagen med den högsta direktavkastningen köpes och de med den lägsta blankas. Den andra handelsstrategin innebär att de företag med den största positiva utdelningsförändringen köpes och d
Uppsatsen undersökte en alternativ metod att kreditbetygsätta företagsobligationer. Metoden är baserad på en modell ursprungligen skapad av Merton (1974) och har modifierats av Byström (2003). Undersökningen utformades som en jämförelsestudie mellan kreditbetyg från kreditvärderingsföretaget Moody’s och mått på konkursavstånd beräknade ur Byströms modell. Modellen gör antagandet om effektiva kapit
Åska hör till ett av de farligaste fenomenen som finns i vår atmosfär. Intresset av att observera åska har alltid funnits hos människan. Först på senare tid har man börjat förstå fysiken bakom fenomenet, även om det fortfarande finns många luckor i kunskapen. Sedan 2000 använder Danmarks Meteorologiska Institut blixtlokaliseringssystemet IMAPCT, som bland annat registrerar nedslagspunkt, strömstyrThunderstorms are one of the most dangerous phenomena in our atmosphere. Mankind has always been interested in observing thunderstorms. It is only recently that we have begun to understand the physics behind this phenomenon. However, there are still many gaps in the knowledge. Since 2000, Denmark has been using the lightning locating system IMPACT which registers strike point, average amperage and
Denna uppsats avhandlar IFO insats - öppenvård vuxna missbruk, som är en organisation tillhörande Arbetsmarknads- och socialförvaltningen Malmö stad. IFO står för Individ och Familjeomsorg, och är en insats klienter kan bli beviljade under missbruksproblematik. Vi kommer i denna uppsats beteckna denna organisation med “IFO insats”. Under 2019 påbörjades en diskussion kring öppenvården i Malmö. En
On July 1st., 2013 the Swedish rape legislation was changed with the introduction of the prerequisite particulary exposed situation that replaced the previous prerequisite helpless state. The motive for this change was, among other things, that the courts had been too restrictive in their adjudication of the prerequisite helpless state. Furthermore, it seemed impossible to investigate and prosecut
The criminalization of letting children witness domestic violence entered into force in Swedish law on 1 July 2021 and is thus a relatively new offence. It is found in Section 4. Chapter 3. in the Swedish Criminal Code and means that it is now a criminal offence to expose a child to witnessing domestic violence. The purpose of the penalty provision is to notice and give legislative protection to c
Något som är det största hindret i arbetet mot terrorism är att vi inte kan nå kon-sensus om vad terrorism är och vilka som klassas som terrorister. Detta skapar stor förvirring inom både akademins tolkning av fenomenet men också inom me-dias rapportering av det. Denna studie syftar till att förtydliga begreppet genom att undersöka hur akademin och media på olika sätt tolkar och använder sig av beOne great obstacle in the war against terrorism is the fact that we can’t seem to agree upon its definition and on who we call terrorist. This confusion can be found in both the academic world and in the media. This study aims to shed light on this issue and highlight one aspect of the concept by looking more closely into the case of the Norvegean man Anders Behring Breivik and the massmurders he

This systematic literature review investigates the relationship between air pollution exposure and inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC). Despite the growing concern over air pollution's impact on various health outcomes, studies specifically addressing effects on the digestive system, particularly IBD, are relatively rare. This review aims
Does sertraline provide symptomatic relief for chronic breathlessness in people with advanced disease whose underlying cause(s) are optimally treated?223 participants with chronic breathlessness (modified Medical Research Council breathlessness scale ≥2) who had optimal treatment of underlying cause(s) were randomised 1:1 to sertraline 25-100 mg (titrated upwards over 9 days) or placebo for 4 week
After the latest Permian mass extinction event, microbial mats filled the ecological niche previously occupied by metazoan reefs, resulting in widespread microbialites. This study focuses on the lipid biomarker (molecular fossil) and invertebrate fossil records from Neotethyan platform margin sections to understand microbial-metazoan bioherm formation. Here, we find that early Griesbachian thrombo
The land-atmosphere exchange of methane (CH4) and carbon dioxide (CO2) in a high-Arctic wet tundra ecosystem (Rylek ae rene) in Zackenberg, north-eastern Greenland, was studied over the full growing season and until early winter in 2008 and from before snow melt until early winter in 2009. The eddy covariance technique was used to estimate CO2 fluxes and a combination of the gradient and eddy cova
Mucosal surfaces of the reproductive tract as well as their secretions have important roles in preventing sexual transmission of HIV-1. In the current study, the majority of the intrinsic anti-HIV-1 activity of human seminal plasma (SP) was determined to reside in the cationic polypeptide fraction. Antiviral assays utilizing luciferase reporter cells and lymphocytic cells revealed the ability of w
One of the major roles of seminal plasma is to provide antimicrobial protection for the spermatozoa in the female reproductive tract. We found that the bactericidal activity of seminal plasma was highest after resolution of the seminal clot and that this antibacterial activity subsequently became greatly diminished. The antibacterial activity was derived from peptides generated by fragmentation of
The balance between self-renewal and differentiation is crucial for the maintenance of hematopoietic stem cells (HSCs). Whereas numerous gene regulatory factors have been shown to control HSC self-renewal or drive their differentiation, we have relatively few insights into transcription factors that serve to restrict HSC differentiation. In the present work, we identify ETS (E-twenty-six)-related
In the course of 2000s, the region of Campania in southern Italy and its capital city Naples became global icons of waste mismanagement after the images of piles of rubbish occluding their urban areas hit the headlines. Conventional explanations, in Italy and elsewhere, pointed to administrative failure, cultural backwardness and mafia infiltration as the main causes of waste mishandling. In the s
The transcription factor Sox4 has been proposed to underlie the increased type 2 diabetes risk linked to an intronic single nucleotide polymorphism in CDKAL1. In a mouse model expressing a mutant form of Sox4, glucose-induced insulin secretion is reduced by 40% despite normal intracellular Ca2+ signaling and depolarization-evoked exocytosis. This paradox is explained by a fourfold increase in kiss
