In the past decades technological innovations in many scientific fields, such as molecular biology, biochemistry electrophysiology and histochemistry have facilitated enormously the degree of resolution of independent variables, in addition to accelerating the production of results and read-out parameters. Consequently, this has resulted in new scientific insights. Similarly, a lot of technolog...

BACKGROUND Traditional government policies suggest that upstream investment in scientific research is necessary and sufficient to generate technological innovations. The expected downstream beneficial socio-economic impacts are presumed to occur through non-government market mechanisms. However, there is little quantitative evidence for such a direct and formulaic relationship between public in...

C hristensen’s (1997) original theory focused on disruptive technologies. Over time, the same theory has been used to explain all kinds of disruptive innovations. This is a mistake. Different kinds of innovations have different competitive effects and produce different kinds of markets. They should be treated as distinct phenomena. This article summarizes what the academic literature has to say...

The rapid diffusion of mobile Information and Communication Technologies (ICT) such as laptops, mobile phones and to some extent Personal Digital Assistants (PDAs) has along with the uptake of email, instant messaging and other networking services (Sørensen et al., 2002; Mathiassen and Sørensen, 2003) rapidly fueled the mobilisation of interaction (Kakihara and Sørensen, 2001). Since technologi...

In this technical report we study the convergence of Parareal for 2D incompressible flow around a cylinder for different viscosities. Two methods are used as fine integrator: backward Euler and a fractional step method. It is found that Parareal converges better for the implicit Euler, likely because it under-resolves the fine-scale dynamics as a result of numerical diffusion.

Does technological change amount to accumulation of general, and so transferable, human capital? To approach this question I rely on a theoretical framework in which the “technology distance” between industries reduces inter-industry transferability of workers’ skill. Empirically, I use US panel data on individual intra-industry and inter-industry mobility decisions between 1982 and 1990, a per...

The value function of an optimal stopping problem for a process with Lévy jumps is known to be a generalized solution of a variational inequality. Assuming the diffusion component of the process is nondegenerate and a mild assumption on the singularity of the Lévy measure, this paper shows that the value function of problems on an unbounded domain with infinite activity jumps is W 2,1 p,loc . A...

The purpose of this chapter is to explore and suggest how perceptions of the social context of an organization moderate the usage of an innovative technology. We propose a research model that is strongly grounded in theory and offer a number of associated propositions that can be used to investigate adoption and diffusion of mobile computing devices for business-to-business (B2B) interactions (...

We consider the problem of large deviations for a two-time-scale reflected diffusion process, possibly with delays in the dynamical terms. The Dupuis-Ellis weak convergence approach is used. It is perhaps the most intuitive and simplest for the problems of concern. The results have applications to the problem of approximating optimal controls for twotime-scale systems via use of the averaged eq...

Prior literature on innovation diffusion or acceptance has almost exclusively concentrated on consumers’ positive attitudes and behaviors for new products/services. Consumers’ negative attitudes or behaviors to innovations have received relatively little marketing attention, but it happens frequently in practice. This study discusses consumer psychological factors when they try to learn or use ...
