Connectivity analysis of the global shipping network by eigenvalue decomposition

ABSTRACT

Maritime shipping necessitates flexible and cost-effective port access worldwide through the global shipping network. This paper presents an efficient method to identify major port communities, and analyses the network connectivity of the global shipping network based on community structure. The global shipping network is represented by a signless Laplacian matrix which can be decomposed to generate its eigenvectors and corresponding eigenvalues. The largest gaps between the eigenvalues were then used to determine the optimal number of communities within the network. The eigenvalue decomposition method offers the advantage of detecting port communities without relying on a priori assumption about the number of communities and the size of each community. By applying this method to a dataset collected from seven world leading liner shipping companies, we found that the ports are clustered into three communities in the global container shipping network, which is consistent with the major container trade routes. The sparse linkages between port communities indicate where access is relatively poor.     

Career development for women in maritime industry: organisation and socialisation perspectives

For centuries, the maritime industry has been a recognised place in society dominated solely by men, and even though there were women involved, they were mostly on the periphery. This research aims to fill the gap of women’s career development in this field, by investigating the relationships among the degree of organisational socialisation, women’s workplace culture, and the career development of women in the maritime workplace. The analyses are conducted with the structural equation model with 202 valid questionnaires. The results indicated that women’s workplace culture has a significantly negative relationship with the degree of organisational socialisation, and then in turn, it has a significantly positive relationship with women’s career development in the maritime industry. Finally, the results also indicate that the mediating effect of organisational socialisation existed between women’s workplace culture and women’s career development. According to the empirical analysis, this study makes conclusions as well as suggestions for the maritime enterprises as the reference for human resource management.
