Conference paper (peer-reviewed)abstract
- Dynamic spectrum access (DSA) schemes allow the users to share spectrum resources by taking advantage of the variations in spectrum demand over time and space. Carrying out dynamic spectrum allocation centrally, however, can be a complex task. For this reason, distributed schemes in which users can access the available channels independently may be preferable to centralized DSA schemes. Cognitive radio systems, which enable user terminals to sense their environment and form their action accordingly, are particularly well-suited for distributed systems. On the other hand, the freedom in distributed schemes gives the users the option to act selfishly, which has decisive effects on system performance. In this paper we consider a distributed multichannel wireless random access system where users selfishly access the channels in the system. We analyze the behavior of the selfish users by modeling the system as a non-cooperative game and we identify all stable operating points (Nash equilibria) of this game. We then compare the performance of this system with a number of cooperative distributed DSA schemes in terms of user utilities. Our results show that the performance of the selfish multichannel random access system can be comparable to cooperative schemes.

Book chapter (peer-reviewed)abstract
- The future of nations and nationalism appears to many to be more uncertain than ever in view of the growing interdependence of the planet. The question of whether globalization heralds the end of nationalism cannot be answered properly without distinguishing between nation and state. In the case of the state, the question is whether states can preserve their sovereignty intact in an age when politics is conducted at a supranational and subnational level. In the case of the nation, the question is whether there are forms of community that offer alternative foci of belonging. Even though the nation continues to be an important source of political and cultural identity, it can be argued that globalization has increased people's reflexiveness with regard to their identity and facilitated the emergence of new forms of belonging that are deterritorial, plural, and hybrid.

Book chapter (peer-reviewed)abstract
- Drawing upon recent literature, which employs social networks in the field of project management, the aim of this research is to empirically investigate the importance of projects’ social capital for knowledge development in R&D projects. Primary data were collected via sociometric questionnaires on a population of 53 biotech R&D projects located at one of the most important science parks in Sweden. The analysis focused on the distinctive structural configuration of projects’ social capital, among which the roles of network diversity were emphasized. Our results suggest that certain structural configurations of project social capital maximize the level of effectiveness in knowledge development. More specifically, we found an inverted U-shaped relationship between projects’ network diversity and their level of knowledge development, demonstrating that intermediate levels of diversity maximize project knowledge development. Implications for innovation managers and policymakers are discussed.
