Existing studies of this topic have not made enough use of the British archives. Nor have they analysed the American domestic response to UDI in sufficient depth. The policies of successive American administrations as regards the Rhodesian problem can only be fully understood as part of Washington’s attitude to Britain, to Africa in general, and to southern Africa in particular. And, because the issue of white minority rule in Africa raised powerful emotions both in the African American community and among white opponents of civil rights, the Rhodesian crisis became a part of the politics of racial equality within the USA, playing a key role in the developing ideologies of these two communities. This thesis is based on research in both American and British archives and aims to show that the prevailing interpretation, especially of the policies of the Johnson Administration once Rhodesia had made its illegal declaration of independence in November 1965, is mistaken. Scholars have tended to take at face value the oft-repeated claim of US policy-makers that Rhodesia was a British problem, that they wished to be no more than helpful bystanders, supporting British efforts to see the downfall of the illegal regime and the creation of a government based on majority rule, and that when they did intervene, it was merely to urge the British to be firmer in their resolve to end the rebellion. The central contention of this thesis is that the officials shaping African policy in the Johnson Administration were intimately involved in the management of the crisis and that, far from resisting a solution that legitimised the white minority regime, they actively encouraged the British to settle with the illegal government.

It always exists different methods/models to build a yield curve from a set of observed market rates even when the curve completely reproduces the price of the given instruments. To create an accurate and smooth interest rate curve has been a challenging all the time. The purpose of this thesis is to use the real market data to construct the yield curves by the bootstrapping method and the Smith Wilson model in order to observe and compare the performance ability between the models. Furthermore, the extended Nelson Siegel model is introduced without implementation. Instead of implementation I compare the ENS model and the traditional bootstrapping method from a more theoretical perspective in order to perceive the performance capabilities of them.

The thesis is focused on finding the most appropriate method for constructing the yield curve which will meet the criteria of Solvency II and also the selected evaluation criteria. An overview of advantages of each method is obtained by comparing these methods. Yield curves are constructed using the Czech interest rate swap data from 2007 to 2013. The selection of the evaluated methods respects their public availability and their practical application in life insurance or central banks. This thesis is divided into two parts. The first part describes the theoretical background which is necessary to understand the examined issues. In the second part the analysis of selected methods was carried out with detailed evaluation.
