Stock return, risk and asset pricing

This thesis attempts to address a number of issues that have been identified in the asset pricing literature as essential for shaping stock returns. These issues include the need to uncover the link between the macroeconomic variables and stock returns. In addition to this, is the need to decide, in light of the findings of the literature, whether to advise investors to include idiosyncratic risk and downside risk as risk factors in their asset pricing models. The results presented here suggest, consistent with other previous studies, that stock returns are a function of a number of previously identified risk factors along with the wider set of macroeconomic variables. These macroeconomic variables could be represented by a number of estimated macro factors. However, only one of these estimated factors emerged as significant in explaining the cross-section of stock returns. Nevertheless, it is important to note that the size (SMB) and value (HML) factors remain important factors in explaining the cross sectional returns on UK stocks, even with the existence of the other risk factors. This finding of inability of the examined macroeconomic variables to capture the pricing power of the SMB and the HML may cast doubt on the possibility of finding more macroeconomic factors that are able to account for these two factors in the cross section of returns in the UK. Interestingly, this conclusion seems to contradict previous authors' findings of potential links in the UK market. The results also support past studies that find that downside risk is an important risk factor and by allowing the downside risk premium to vary with business cycle conditions, downside risk might be a better measure of risk than market risk. Nevertheless, this thesis shows that although this finding is applicable in times of economic expansion, during recession, there is no conclusive relationship between . downside risk and stock returns. Furthermore, this thesis supports the studies which find that idiosyncratic risk is not significant in pricing stocks. However in contrast to other studies, it reveals this by showing that time-varying risk could be the reason behind the potentially illusive findings of idiosyncratic risk effect. This thesis confirms that, for London Stock Exchange investors, macroeconomic variables should never be overlooked when estimating stock returns and downside risk could be an influential risk factor

Patient Individualized Therapy – From Patient Education to Molecular Biomarkers

Für diese Arbeit wurden zwei verschiedenen Projekte zum Thema personalisierte Medizin durchgeführt. Bei dem ersten Projekt handelte es sich um eine klinische Studie, die die Langzeiteffekte einer komplexen Schulung für Patienten mit oraler Antikoagulation untersuchte. An der cluster-randomisierten Studie nahmen 367 Patienten in 22 allgemeinmedizinischen Praxen teil. Die komplexe Intervention bestand aus einem Video, einer Broschüre und einer individuellen Schulung mithilfe einer medizinischen Fachangestellten. Die Kontrollgruppe erhielt lediglich die Broschüre. Primäre Endpunkte waren der Wissenszuwachs nach sechs Monaten, gemessen mithilfe eines selbstentwickelten Fragebogens, und die Stabilisierung der INR. Nach sechs Monaten wussten die Patienten in der Interventionsgruppe signifikant mehr als vor der Schulung, während Patienten in der Kontrollgruppe keinen signifikanten Wissensunterschied zeigten. Das komplexe Schulungsprogramm verbessert das Wissen, das für eine sichere und effektive Therapie der Patienten mit oralen Antikoagulantien notwendig ist, deutlich. Im zweiten Projekt wurde der Einfluss von genetischen Polymorphismen auf die Aufnahme von Antidepressiva in der Leber analysiert. Fast 10% der kaukasischen Bevölkerung besitzen aufgrund von genetischen Polymorphismen kein aktives OCT1. Es wurde analysiert, ob es sich bei Venlafaxine und O?Desmethylvenlafaxin um Substrate von OCT1 handelt und ob bekannte und häufig auftretende OCT1-Varianten einen Einfluss auf die Aufnahme haben. HEK293-Zellen, die entweder OCT1 oder eine bekannte genetischen OCT1-Funktionsverlustvarianten Arg61Cys überexprimieren, wurden verwendet. Die Aufnahme von Venlafaxin veränderte sich in den OCT1-überexprimierenden Zellen nicht im Vergleich zu den Kontrollzellen. Bei O?Desmethylvenlafaxin führten die OCT1-überexprimierenden Zellen zu einem 1,96-fachen Anstieg in der Aufnahme. Die Funktionsverlustvarianten führten zu keiner Aufnahme von O?Desmethylvenlafaxin.The aim of this work was to analyze two different projects concerning personalized medicine. The first project was a clinical study designed to assess and evaluate the long-term effects of a complex nurse-based patient education program for patients receiving oral anticoagulants. The study population consisted of 367 patients in 22 general practices recruited to a cluster randomized trial. The education consisted of a video, a brochure and individual training by a nurse while the control group received a brochure only. Primary endpoints were changes in knowledge after six months measured by a self-developed questionnaire and stabilization of the INR. After six months the patients randomized to the intervention group knew significantly more than before the education program, while patients randomized to the control group had no significant changes in level of knowledge. In the second project the effects of genetic polymorphisms on antidepressant transport in the liver were analyzed. Close to 10% of Caucasians are lacking active OCT1 due to loss-of-function polymorphisms. Venlafaxine and O?desmethylvenlafaxine were analyzed to determine whether they are substrates of OCT1, and whether common loss-of-function OCT1 polymorphisms may affect the uptake of venlafaxine and O?desmethylvenlafaxine. HEK293 cells overexpressing OCT1 and common OCT1 variants carrying the loss-of-function polymorphisms were used. Venlafaxine uptake in HEK293 cells did not change after OCT1 overexpression. In contrast, O?desmethylvenlafaxine uptake increased 1.96-fold in OCT1-overexpressing HEK 293 cells. The increase of O?desmethylvenlafaxine uptake was reversed by the the common loss-of-function polymorphisms

Entropy and entanglement in a bipartite quasi-Hermitian system and its Hermitian counterparts

We consider a quantum oscillator coupled to a bath of $N$ other oscillators. The total system evolves with a quasi-Hermitian Hamiltonian. Associated to it is a family of Hermitian systems, parameterized by a unitary map $W$. Our main goal is to find the influence of $W$ on the entropy and the entanglement in the Hermitian systems. We calculate explicitly the reduced density matrix of the single oscillator for all Hermitian systems and show that, regardless of $W$, their von Neumann entropy oscillates with a common period which is twice that of the non-Hermitian system. We show that generically, the oscillator and the bath are entangled for almost all times. While the amount of entanglement depends on the choice of $W$, it is independent of $W$ when averaged over a period. These results describe some universality in the physical properties of all Hermitian systems associated to a given non-Hermitian one
