In order to distribute earnings to shareholders, besides cash dividend, the firms can also buy back shares. However, compared to cash dividends, share repurchases are less common. Therefore, the thesis only focuses on cash dividend policy of the firms. Specifically, the thesis studies the dividend payment policy of 460 firms listed on HSX and HNX between 2010 and 2016. The data is collected from 2009 to 2017. The data needed for research is extracted from the Datastream database. The final sample includes 2,653 firmyear observations.

The fission gas release microscopic model of the mechanistic code MFPR is further developed for modelling of enhanced release from irradiated UO2 fuel under transient conditions of the power ramp tests, along with the microstructure evolution characterised by the formation of a new population of large intragranular bubbles with a rather wide size distribution (from 30 to 500 nm), observed in transient-tested UO2 fuel samples.

For hundreds of years, business people have been transmitting their wisdom generation to generation. In the middle 1990’s companies started to create units focused in managing their knowledge. Nowadays, Knowledge Management is still a relatively new discipline focused in developing the main competitive advantage that organizations have: the intellectual assets. Organizations recognise that Social Media can be enormously used to influence their customers. However, they exactly do not know how to confront this new tool.

This thesis has been done in an effort to investigate how euphemism is translated from English into Vietnamese in translated works as well as to find out what are the main approaches taken by translators in translating euphemism from English into Vietnamese. A collection of samples taken from literary works written in English and their Vietnamese versions have been analyzed to explore ways in which euphemisms are transferred. Besides, quantitative analyses have also been carried out to show distribution of ways of translating, on the basis of which to identify preferences....

This thesis presents time-resolved measurements of the spin evolution of transient carrier populations in III-V quantum wells. Non-equilibrium distributions of spin polarisation were photoexcited and probed with picosecond laser pulses in three samples; a high mobility modulation n-doped sample containing a single GaAs/AlGaAs quantum well, an In0.11Ga0.89As/GaAs sample containing three quantum wells and, a multi-period GaAs/AlGaAs narrow quantum well sample.
