As empirical studies have found that large complex networks (e.g., WWW) are scale-free, the preferential attachment model is commonly applied to generate this network topology. This model assumes a node with higher degree is more likely to gain a new link, and ignore node attributes except the...

Through the advancement of information technology, a new type of innovation could emerge. This innovation type suggests a leading company to open up its software service platform to customers as well as competitors. Many innovation studies have been performed in the past, in order to understand...

Cloud computing, which can be described as a technology for provisioning computing infrastructure as a service, runtime platform as a service, and software as a service, is considered as a keystone for innovation in the IT area. However, a limiting factor to innovation through cloud computing...

The Energy and Greenhouse Gas (GHG) Target Management System (TMS) is one of South Korea’s major instruments to achieve national energy policy as well as GHG reduction targets. The TMS was introduced in the late 1990s, focusing on energy only and aiming to reduce the level of South Korea’s...

Although their advantages are well-known, technology alliance may not always positively affect innovative performance. Previous studies have found several explanations for this problem. Technology alliances often require excessive resources and capabilities to form and maintain relationships...

Social networks can be differentiated according to the type of entities (i.e., humans or objects) that are represented within them. These networks can be called human networks and social object networks, respectively. Actors in human networks can act strategically to maximize their own payoffs...

The power of using knowledge against competitors is a key success factor in the information age. However, the knowledge itself is not the source of competitive advantage for an organization; rather its power lies in its use. In a learning organization, collective knowledge of the individuals is...

Service networks can be considered to be open innovation systems. It has led to research on the structure of these networks, concentrating on the static network topology and its effect on innovation. However, the research misses the changes of network positions over time. In this paper, we...

The increased concerns about climate change have made renewable energy sources an important topic of research. Several scholars have applied different methodologies to examine the relationships between energy consumption and economic growth of individual and groups of countries and to analyze...

People-to-people interactions in the real world and in virtual environments (e.g., Facebook) can be represented through complex networks. Changes of the structural properties of these complex networks are caused through a variety of dynamic processes. While accepting the fact that variability in...
