This paper reports a study of information and communication technology (ICT) use in Norway and the United States. Forty-two depth interviews completed in both countries provide the data source. Using grounded theory as a research method, and Adaptive Structuration Theory as our conceptual base, we analyze these interviews to generate an empirical model of ICT use. The 1490 incidents identified ...

Some studies hypothesize a strong interdependence between speech and tool use development in the first two years of life. To help understand the underlying mechanisms, we present the first robotic model learning both speech and tool use from scratch. It focuses on the role of one important form of body babbling where exploration is directed towards self-generated goals in free play, combined wi...

In this paper we investigate performance of global communications in a particular parallel code. The code simulates dynamics of expansion of premixed spherical flames using an asymptotic model of Sivashinsky type and a spectral numerical algorithm. As a result, the code heavily relies on global all-to-all interprocessor communications implementing transposition of the distributed data array in ...

We present an agent-based model of a multi-tier energy market. We show how reward interdependence between strategic business units within a vertically integrated firm can increase its profits in oligopolistic energy markets. The effects are shown to be distinct from those of the raising rivals’ costs model. In our case, higher prices relate to the nature of energy markets, which facilitate the ...

With big data growing rapidly in importance over the past few years’, academics and practitioners have been considering the means through which they can incorporate the shifts these technologies bring into their competitive strategies. To date, there has been an emphasis on the technical aspects of big data with limited attention on the organizational changes they entail and how they should be ...

ICT clusters have attracted much attention because of their rapid growth and their value to other economic activities. We examine the drivers of ICT activity in 227 cities across 22 European countries. We examine the national business environment along with city-level factors to identify important factors which influence ICT clustering. We address interdependencies at different levels using a n...

Institutions have been proposed as a means to regulate open interaction systems by introducing a set of norms (involving deontic positions like authorizations, obligation, prohibition and permissions) and to define the ontology of the context in which agents interact. To better clarify the interdependence existing among deontic positions and the ontology defined by each institution, in this pap...

We propose a static approximation of dynamic demand substitution behavior based on a fluid network model and a serviceinventory mapping. This approximation greatly enhances our ability to analyze the interdependent inventory/service, price, and product assortment decisions in noncompetitive and competitive scenarios with demand substitution. We demonstrate that the approximation is well behaved...

This paper contrasts two views about the relationship between the processes of access and mapping in analogymaking. According to the modular view, analog access and mapping are two separate ‘phases’ that run sequentially and relatively independently. The interactionist view assumes that they are interdependent subprocesses that run in parallel. The paper argues in favor of the second view and p...
