This paper examines the impacts of Eurozone sovereign credit rating announcements by three leading rating agencies on exchange rates from January 1, 2009 to March 31, 2011. Firstly we report the mean and volatility of USD/EUR in response to Eurozone sovereign rating news. Secondly, thanks to the high integration in Europe, we extend our analysis to the movement of USD/SEK in order to see how non-E
This paper models the dynamics of capital structure listed on the NYSE and NASDAQ during 1995 to 2010. The subsamples classified by given leverage level and specified periods of time are tested. The main contribution is that macroeconomic conditions and firm characteristics are incorporated regressed for non-linearity test. We provide the evidence of non-linear patterns among low leverage and high
The thesis is based on a qualitative multiple case study with an abductive approach. It examines the relationship between brand placement and gender roles in films between the 1980s and 2010s, with the main purpose to contribute to the gender and marketing literature on how the portrayal of male and female characters in films has developed, changed and been translated through brand placement withi
As a civil servant in the East India Company and witness to government expansion and reorganization in the mid-nineteenth century, John Stuart Mill developed an interest in civil service reform. In an essay supporting the 1854 Northcote-Trevelyan Report and his later political treatises, Mill argued for competitive civil service recruitment. These writings have been relatively neglected by Mill sc
The COVID-19 pandemic may have severe impact on mental health, and concerns have been raised about potentially increased online behavior and possibly increased gambling problems, such as in sports bettors at risk of transfer to even riskier forms of gambling during sports lock-down. Given the need for objective data about gambling behavior during the pandemic, the present analysis, from a project
During liquefaction of the ejaculate, the semen coagulum proteins semenogelin I (SEMG1) and semenogelin II (SEMG2) are degraded to low molecular mass fragments by kallikrein-related peptidase 3 (KLK3), also known as prostate-specific antigen. Semenogelin molecules initiate their own destruction by chelating Zn2+ that normally would completely inhibit the proteolytic activity of KLK3. In a similar
The factor Va (FVa) inactivation by activated protein C (APC), mediated by cleavages at Arg306 and Arg506 in FVa, is inhibited by both factor Xa (FXa) and prothrombin. While FXa is known to specifically inhibit the Arg506 cleavage, the effect of prothrombin has not been confined to one cleavage site. We used recombinant FV variants, FV:506Q/679Q and FV:306Q/679Q, to investigate the effect of proth
The purpose of this thesis is to obtain microlocal analogues of results by L. Hörmander about inclusion relations between the ranges of first order differential operators with smooth coefficients which fail to be locally solvable. Using similar techniques, we shall study the properties of the range of classical pseudo-differential operators of principal type which fail to satisfy condition (ψ).
The transmission of vibrations over the surface of the ground, due to a moving, vertical harmonic rectangular load, is investigated theoretically. The interior of the ground is modelled as an elastic half-space. The transformed solutions are obtained using the double Fourier transform. Numerical results for the displacements on the surface are presented for loads moving with speeds up to the Rayle
Asymmetrical flow field-flow fractionation (AF4) is rapidly becoming a technique of choice for the separation and characterization of complex materials. It is capable of fractionating samples over a wide size (similar to 2 nm to 50 mu m in diameter) and molecular weight range (10(3)-10(10) g/mol). It offers gentle, low shear, low pressure separation conditions which are essential to preserve the s
In recent times, trilayer graphene has attracted wide attention owing to its stacking and electric-field-dependent electronic properties. However, a direct and well-resolved experimental visualization of its band structure has not yet been reported. In this paper, we present angle-resolved photoemission spectroscopy data which show with high resolution the electronic band structure of trilayer gra
The area of autonomous parking attracts a great deal of attention from the research community and the automobile industry. Research has showed that many robotic navigation systems fail to deliver the performance and flexibility of animal navigation techniques, even though they are both mathematically and technologically complex. Biomimetic robotic research, i.e., research that tries to mimic biolo
The European Union's (EU) external appearance is often described as a ?civilian power? (CP). However, due to increasing military capabilities and coercive approaches in international politics, it apparently moves towards a ?harder? kind of power. Applying a role-theoretical approach, the study explores what kind of power the EU actually constitutes and thus studies whether the EU's charact
In 1979 the Sandinista movement revolted against the Somoza dictatorship and seized power in Nicaragua. The Swedish Social Democrats had earlier supported the Sandinista movement in Nicaragua and now welcomed the revolution. During 1979 and 1990 the Swedish policy on Nicaragua proved stable. The political support and the flow of financial aid were continuous despite changes of government, internal
