Mobile operators have made massive investments in spectrum and infrastructure to provide mobile broadband content services on ‘mobile Internet’. Faced with considerable uncertainty regarding market growth, technology options and regulatory policies, the introduction of broadband services...

Large design and manufacturing projects are conducted in elaborate settings. Interdependent specialists work together, building complex systems. A substantial part of their daily work concerns the coordination of distributed work. This paper reports from a field study at Foss Electric, a Danish...

Mobile communications are permeating virtually every aspect of our lives. The market is experiencing rapid improvements in technologies, while mobile operators are trying to figure out new ways their infrastructures can provide services to the customers. Furthermore, user-innovation with new...

The dynamics of nominal bond yields and the stock index are modelled within a continuous-time general equilibrium economy. Closed-form solutions are provided for both the term structure of nominal interest rates and the equilibrium value of the stock index where the value of the stock index is...

The stochastic behavior of agricultural commodity prices is investigated using observations of the term structures of futures prices over time. The continuous time dynamics of (log‐) commodity prices are modeled as a sum of a deterministic seasonal component, a non‐stationary...

The conceptual framework for understanding the logical Internet is based on the construction of a horizontal, layered architecture, which differentiates between physical-, data link-, network-, transport-, and application layers (1). This is different from the telecommunication networks model...
