However, in the field of the concession addresses, the studies on this kind of political text are limited. The winners of presidential election always draw much attention from the world and their speeches, for example, presidential inaugural address has been a hot study topic of linguistics. Nevertheless, the losers of presidential election are always neglected by the world and the study on concession address is scarce and rare. Therefore, the meaning of study on the concession speech helps fill the gap of the discourse analysis. This thesis applies the PDA under the framework of appraisal theory to analyze five concession speeches with a combination of qualitative and quantitative approaches. This study aims to complement CDA （Critical Discourse Analysis） to emphasize positive social construction of political discourse.展开更多

The value of these clauses may be important and should be added to the total value of the concession. However, in these cases, traditional valuation techniques, like the NPV （net present value） of the project, are insufficient. An alternative methodology for the valuation of highway concession is one based on the real options approach. This methodology is generally built on the assumption of the evolution of traffic volume as a GBM （geometric Brownian motion）, which is the hypothesis analyzed in this paper. First, a description of the methodology used for the analysis of the existence of unit roots （i.e., the hypothesis of non-stationarity） is provided. The Dickey-Fuller approach has been used, which is the most common test for this kind of analysis. Then this methodology is applied to perform a statistical analysis of traffic series in Spanish toll highways. For this purpose, data on the AADT （annual average daily traffic） on a set of highways have been used. The period of analysis is around thirty years in most cases. The main outcome of the research is that the hypothesis that traffic volume follows a GBM process in Spanish toll highways cannot be rejected. This result is robust, and therefore it can be used as a starting point for the application of the real options theory to assess toll highway concessions.展开更多
