This 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
Syfte: Att undersöka vilka barriärer sjuksköterskor upplever vid sexuell rådgivning till personer med hjärtsjukdom. Metod: Studien genomfördes som en integrerad litteraturstudie där totalt åtta artiklar, varav tre kvalitativa, fyra kvantitativa och en mixad metodartikel, inkluderades. Resultat: I resultatet framkom två huvudkategorier av barriärer, Yttre faktorer och Inre faktorer, med vardera två
The sharing economy, which is an Internet-mediated economic model based on sharing practices, presents the potential to reshape nature-society interactions with relevance for leading to transformative change for environmental and social aspects of sustainability. It is widely presented as a model leading to environmentally sustainable pathways through reduced resource use and reduced levels of con
China has experienced unprecedented economic success since the liberalisation process began in 1978. However, this expansion has also brought with it large scale environmental damage. Using data obtained from the Chinese National Buraeu of Statistics, this study investigates CO2 emissions from the years 2000 – 2012 on a provincial level in comparison with company state and private ownership struct
E-post och dokument kan innehålla ostrukturerade personuppgifter och används flitigt av företag i dagens digitaliserade värld. I maj 2018 kommer en ny dataskyddsförordning GDPR att verkställas och ersätter då PuL. Detta innebär en förändring för samtliga företag i Sverige då deras arbetssätt kring ostrukturerade personuppgifter tvingas att förändras. Studiens syfte är att undersöka hur företag för
This thesis aims to shine light on some different machine learning methods. As reference a more common statistical prediction method, namely the generalized linear model, is applied to compare the results of the machine learning methods. Six different machine learning methods are investigated. These methods are explained in detail and used to predict hit rates within insurance customers. To further
Bygg- och rivningsavfall utgör en betydande del av den totala mängden avfall som går till deponi. Genom återvinning kan detta avfall ses som en resurs och ersätta naturligt material. Det krävs att återvinningen av byggnads- och rivningsavfall ökar för att minska mängden som deponeras, vilket samtidigt minskar uttaget av jungfruligt bergmaterial. Aktörerna inom bygg- och anläggningssektorn använder
In recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. Two Higgs doublet models allow new decays at tree-level and the Froggatt-Nielsen mechanism gives an explanat
I takt med den växande digitaliseringen förändras förutsättningarna för arbetslivet och medarbetare ställer nya krav på sina arbetsgivare. Arbetet med Performance Management behöver förnyas för att möta framtidens behov. För att öka förståelsen för vad som får medarbetare att bli engagerade i sitt arbete, granskades IKEA och deras mål- och utvecklingsprocess. En elektronisk enkät skickades ut tillIn pace with the growing digitalization, the conditions for worklife and coworkers are in continuous change, which in turn changes the demands on the employees. The work with Performance Management needs to be updated to meet the requirements of the future. The purpose with this study is to achieve better understanding what makes coworkers engaged in their work in order to increase their performan
I och med min utbildning till lärare i musik- och svenska som andraspråk vill jag låta dessa ämnesområden sammanfläta i mitt examensarbete. I och med den flyktingström som påverkat hela vårt land har skolsituationen i Sverige förändrats. Antalet nyanlända elever i skolan har ökat och många av dem ska få undervisning i musik. Detta är ett uppdrag som musiklärare inte varit beredda på. Därför är syfIn my education, to be a teacher in music and Swedish as a second language, I want these subjects intertwine in my degree project. With increase of refugees in our country, the school situation has changed. The number of new arrivals in school has increased and many of them will be taught in music. This is an assignment that music teacher has not been prepared for. Therefore, the aim of the study
We contribute to the holistic picture of the phenomenon SCE by adding an interpretative perspective, allowing us to critically challenge five assumptions that theoretically underlie its conceptualization. We challenged SCE’s assumptions that: employees have a common understanding and perception of sustainability and CE; that these understandings are in line with SCE theory; that the three dimensio
Due to the depletion of earth’s resources and the growing concern of electronic waste it is important to extend the lifespan of electronic products. Consumers often have the perception that re-used and remanufactured products are of lesser quality than new counterparts. This study aims to evaluate if a more comprehensive sustainability certification scheme for electronic products, covering criteri
This thesis proposes an autoregressive credit spread model to make long term simulations of credit spreads and credit indices in the Investment grade and High yield bond segments. Several models are tested, and the final spread model produces simulations with statistics consistent with historical data, even though the model itself is relatively parsimonious. A transition from spread to index is pro
Social service workers documentation and emotional labour – a qualitative study about working with documentation The aim of this study is to explore the experience among social service workers in regards to working with documentation and to analyze how it affects their ability to perform emotional labour. Former research has shown that social service workers spend a big part of their work day wor
Everyone who has worked with research knows how rewarding experimenting and developing new algorithms can be. However in some cases, the hard part is not the invention of these algorithms, but their evaluation. To try and make that evaluation easier, this thesis focuses on the collection of data that can be used as positional ground truths using an autonomous measurement platform. This should assi
The use of cloud computing is increasing in many different areas, and one of these areas is education. As using cloud in education becomes standard in many schools, some ethical concern regarding student information arises. This thesis aims to identify the issues that Swedish schools in the region of Skåne are facing regarding the use of cloud computing. This is achieved by creating a theoretical
The performance of five commercial available biobased packaging films for fully-baked frozen bread was studied in comparison to polyethylene (PE) film. The main purpose of this study was to understand how biobased packaging materials affect the quality of fully–baked frozen bread. The five biobased packaging films evaluated in this study were biobased polyethylene (bio-PE), Biodolomer®, polylactic
This paper examines how the exchange rate affects Chinese economic growth. First, we go through the literature about exchange rate and how it affects the economic growth. We respectively analyze the transmission mechanism of RMB real effective exchange rate on the impact of Chinese import, export and foreign direct investment. We use the quarterly data from 1994 to 2016 and the method of cointegra
This work will examine how the British government engaged with Muslim-led organisations through its counter-extremism strategy Prevent in following the London bombings in 2005. Over a period of seven years two governments, Labour and the Coalition, implemented separate version of Prevent which led to distinct forms of state engagement with Muslim-led organisations. By looking at the broader histor
