A Strategic Model for Investment in Korean Shipping Under the New Liberalisation Treaty

Merged with duplicate record 10026.1/1892 on 27.02.2017 by CS (TIS)Following trade liberalisation, shipping has been further affected by the world economic environment. Despite arguments as to whether the nature of the shipping industry is a liberalised one or not, it is now clearly seen as the case by the shipping industry itself. The primary goal of this thesis is to examine the attitudes within Korean shipping circles. An empirical study was carried out to evaluate how shipping is being influenced by liberalisation under the new rules, established by the World Trade Organisation and the Organisation for Economic Co-operation and Development. The null hypothesis was that there would be no substantial changes in Korean Shipping following liberalisation. The null hypothesis was rejected, which means that it was recognised by Korean shipping practitioners that there were significant changes after liberalisation. A further study was undertaken to test for relationships between the perspectives of four groups~ financial managers of shipping companies, bankers, government policy makers and sales managers from shipbuilding companies. It transpired that there was unity in their perceptions of shipping investment. A hypothesised seven-factor strategic model of the shipping industry was initially proposed and re-interpreted following the empirical results. To cope with the new competitive market, strategic options are likely to include tax and registry considerations. Finally, following the financial crisis in Korea last year, which occurred before this research was completed, interviews and a survey were conducted, based on a random selection of previous respondents. This was to establish whether their views had changed. The results revealed that they were now very hesitant to make any new investment decisions given the present situation. However, respondents are sure that there will be no further measures to impede the current liberalisation moves in Korea. Rather they regard this financial crisis as a mechanism to accelerate liberalisation, following the International Monetary Fund's options to dismantle the Korean protectionist barriers

Quartet consistency count method for reconstructing phylogenetic trees

Among the distance based algorithms in phylogenetic tree reconstruction, the neighbor-joining algorithm has been a widely used and effective method. We propose a new algorithm which counts the number of consistent quartets for cherry picking with tie breaking. We show that the success rate of the new algorithm is almost equal to that of neighbor-joining. This gives an explanation of the qualitative nature of neighbor-joining and that of dissimilarity maps from DNA sequence data. Moreover, the new algorithm always reconstructs correct trees from quartet consistent dissimilarity maps.Comment: 11 pages, 5 figure

On extensions of representations for compact Lie groups

Let $H$ be a closed normal subgroup of a compact Lie group $G$ such that $G/H$ is connected. This paper provides a necessary and sufficient condition for every complex representation of $H$ to be extendible to $G$, and also for every complex $G$-vector bundle over the homogeneous space $G/H$ to be trivial. In particular, we show that the condition holds when the fundamental group of $G/H$ is torsion free.Comment: 10 pages, AMS-LaTeX v1.

Classification of equivariant real vector bundles over a circle

This is a continuation of the authors' previous work [math.AT/9910001] on classification of equivariant complex vector bundles over a circle. In this paper we classify equivariant real vector bundles over a circle with a compact Lie group action, by characterizing the fiber representations of them, and by using the result of the complex case. We also treat the triviality of them. The basic phenomenon is similar to the complex case but more complicated here.Comment: 16 pages, AMS-LaTeX v1.
