The growth of Arabian airlines from a German perspective – A study of the impacts of new air services to Asia

Airlines from Bahrain, Kuwait, Qatar, the United Arab Emirates and Oman have gained significant market shares in international air transport. Traditionally travellers have chosen hubs like Amsterdam, Frankfurt, London or Paris as transfer points for trips to Asia. With the inauguration of non-stop services to places like Abu Dhabi, Doha or Dubai, new choices for air travellers have emerged. We analyse data derived from German air transport statistics on the effects of passenger flows between the airports of Düsseldorf and Hamburg to Asian destinations. They suggest that services introduced by Emirates stimulated passenger demand for Asian destinations, while incumbent hubs do not lose transfer passengers. Regarding travel times and connection quality of routings between secondary airports in Germany and Asian destinations, comparing routings of Emirates Airlines and Lufthansa suggests that due to geographic and scheduling constraints, services via Arabia do not constitute a perfect substitute for time-sensitive passengers.     

Portfolio optimization in a defaultable market under incomplete information

We consider the problem of maximization of expected utility from terminal wealth in a market model that is driven by a possibly not fully observable factor process and that takes explicitly into account the possibility of default for the individual assets as well as contagion (direct and information induced) among them. It is a multinomial model in discrete time that allows for an explicit solution. We discuss the solution within our defaultable and partial information setup, in particular we study its robustness. Numerical results are derived in the case of a log-utility function, and they can be analogously obtained for a power utility function.     

Laying the foundations of international careers research

As an editorial to the special issue “new avenues in international careers research” this article discusses the roots of the international careers research stream, which sits at the intersection between career studies, HRM and international management. In order to support future studies in this emerging area of enquiry, we attempt to lay down the foundations of a research agenda based around what we see as the three core areas of interest: contextualised careers research, comparative careers research and careers research in internationally operating organisations. After providing some suggestions for the kinds of theoretical and methodological tools that will be required to build on these foundations, we introduce the five empirical papers that comprise this special issue.

Zur Lage der Kommunikationswissenschaft und ihrer Fachgesellschaft. Ergebnisse der DGPuK-Mitgliederbefragung 2003

Like other broad disciplines in the media/communications field, communication science is characterized by rapid growth and increasing diversity and hence confusion. That also affects the discipline’s scholarly associations. So the German Association for Communication Science (Deutsche Gesellschaft für Publizistik- und Kommunikationswissenschaft, DGPuK), the largest German-speaking association in this field, conducted a survey among its members in early 2003. This article reports on the design and findings of this study, focusing on the perception and evaluation of the association and on the scholarly orientations (theoretic perspectives and methodologies) of its members. Various subgroups within the DGPuK diverge in their positions and opinions. This applies in particular to the less well represented research traditions and subdisciplines (as compared to the social-scientific mainstream), which tend to view the DGPuK as one-sided. Deviations also show for professionals working outside the academic field (as compared to DGPuK members from universities) and in part for older members and women. The findings not only give an up-to-date picture of the state of the DGPuK but also shed light on the situation and development of the discipline as a whole.
