Several researchers have investigated the relationship between credit risk and stock returns, but their findings are ambiguous. While some have found the anomalous relationship that investors pay a negative risk premium when investing in high credit risk stocks, others have presented opposing results. This non-consensus and intriguing results motivated us to further investigate this relationship b
The solar and thermal performance of window is subject to a wide range of parameters. To simulate the energy performance is therefore difficult, and limitations might occur depending on the complexity of each case. This study presents some of the current limitations related to the assessment of window considering solar and thermal performance into the policy framework (standards, regulations and c
Detta examensarbete ämnar undersöka en effektiv Asset and Liability Management (ALM) metod under Solvency II direktiv, med m˚alsättningen att etablera ett optimeringsramverk som hanterar komplexa interaktioner mellan tillg˚ang- och skuldsida. En stokastisk simuleringsmetod kallad least-squares Monte Carlo (LSMC) implementeras för att skatta en proxy funktion för framtida nettotillg˚angsvärden. LSMThis thesis aims to examine an efficient asset and liability management method under Solvency II regulations, and to find an optimization framework that takes complex interactions between assets and liabilities into account. The investigated approach consists of a least-squares Monte Carlo method, where least-squares regression is used to obtain a proxy function for future net asset values. A fair
Saving vultures from extinction: everyone’s business The eminent naturalist Charles Darwin once said vultures were “disgusting”. Well, we cannot argue that they are as cute as fur seals or cheetah puppies. However, these birds have an essential role in nature that needs to be preserved because, in fact, it ultimately benefits us. Vultures eat dead animals, either fresh or putrefied, and in that w
I en tid med hårdare konkurrens än någonsin, är det viktigt att hitta vägar att sticka ut. I ett tidigare projekt i samarbete med ledande kartong- och förpackningstillverkaren Smurfit Kappa AB utvecklades en display för gemensam exponering av kylda och icke kylda varor i livsmedelsbutiker. Systemet bestod av en modul kyld med peltierelement placerad i en golvstående kartongdisplay. Detta examensa
Economists have for a long time tried to explain the motivations behind bequests, why they exist and how they are divided. In Sweden, most bequests are equally divided, which raises the question of what motivates this decision even if there is a will written. This study aims to empirically examine if the Swedish decedents divide their bequests to make up for economic differences among their heirs.
Försurning och övergödning är centrala miljöproblem i Sverige, som bland annat leder till minskad biologisk mångfald. Det svenska skogsbruket kan påverka dessa miljöproblem, bland annat genom att skogsbruksåtgärder som avverkning, gallring och gödsling kan ha inverkan på kvävehalten i avrinnande vatten och bidra till ökad försurning av skogsmark och ytvatten. Stormskador har även visats kunna bidrAcidification and eutrophication are central environmental problems in Sweden, which effects biodiversity. The Swedish forestry may contribute significantly to these environmental problems. The forestry measures that may have a major impact on nitrogen levels in groundwater and increased soil acidification are harvesting, fertilization and whole-tree harvesting. Studies have shown that even storm
This paper aims at demystifying the agile way of working and to improve the understanding of the concept. We do this through a case study of a large bank which initiated a transition to agile five years ago, a transition which can be categorised as an attempt to shift from being bureaucracy to post-bureaucracy. To reach our aim, we engaged in in-depth interviews, observations, and document analysi
Do monetary unions between developing economies support sustainable economic development for the members? Previous research has only considered traditional research methods to examine costs and benefits of monetary unions in developing regions. This thesis applies new measures to determine how the operation of institutions encounters specific problems of developing economies for the case of the Co
Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process. When shifting between gears, the speeds of the target gear and the output shaft it is supported by, have to be synch
The purpose of this thesis is to gain a greater understanding of how “nätvandrare” and “chat supporters” experience the problem of cyberbullying based on a norm perspective. We are using these two groups as temperature sensors. We are studying young people from “Nätvandrare” and “chatsupporters” point of view. Cyberbullying is a subject that is constantly growing in line with digitalization. In th
The purpose of this study is to investigate the effects of gamification on online trust, testing the impact through the use of an e-commerce website, Ebay. The objective of the paper is to discover how a certain type of visual design element implemented on websites impacts users’ extent of online trust. Specifically, this thesis focuses on the use of gamified elements as a website design tool to i
Limited access to formal banking leaves large shares of the population in developing countries underbanked or unbanked. One tool believed to enhance financial inclusion is the financial service mobile money, which has spread quickly especially in Africa. The mobile service offers payment, transfer and banking services to low rates and without the need of a bank account. In Lesotho, mobile money wa
Against all odds – a narrative approach towards underdog brands. This study aims to develop a narrative understanding of how an underdog position is achieved, by investigating underdog brand narrative construction from two cases: Oatlyand Tesla. Underdog brand biography and narrative theory was used to provide a framework of how the brand underdog narrative was encapsulated. By adopting a semiotic
A sports video analysis application was developed by Spiideo for mobile devices. It presents recordings from practices and competitive games for game-play analysis. Available tools, such as on-screen drawings, require a robust background foreground segmentation. The currently used segmentation method have difficulties to master the shifting conditions in weather, shadows and shirt colors. The pu
Introduction: This thesis aims to investigate how a small and young company can implement the management philosophy Lean. The thesis is designed as a literature study with two objectives. The first objective is to identify what Lean is and what its underlying tools, methods and principles are. The first objective is accomplished in the results chapter. The second objective is to investigate how th
The following dissertation examines the relationship between the actual control of insurgent groups, FARC and AUC, in municipalities of Colombia and the subsequent performance of public services. By resorting to a novel semi-parametric, group-based-trajectory model, this paper manages to discern the de facto presence of such groups at the municipality level, which allows carrying out such examinat
