Box 1738, NL-3000 DR Rotterdam, The Netherlands Abstract This paper illustrates that salient features of a panel of time series of annual citations can be captured by a Bass type diffusion model. We put forward an extended version of this diffusion model, where we consider the relation between key characteristics of the diffusion process and features

ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up, two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH, M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm), resulting in the formation of a white ring around the glass closer to the side of the

DIFFUSION OF TECHNOLOGY Introduction Several studies have been conducted on adoption of technology, but the most outstanding adoption model is provided by Rogers in his book, Diffusion of innovations. Medlin (2001) notes that Rodgers’ diffusion of innovations theory is the best suitable for exploring the adoption of technology in the educational setting. In most cases, research in diffusion incorporates technological innovations thus (Rodgers, 2003) uses the term “innovation” and “technology” synonymously

and often unpredictable consequences when widely adopted and complex factors shape their spread, adoption, or rejection within human communities and societies. Change often (page 227) happens by innovations and discoveries within society, both scientific/technical and socio-cultural. Innovative action involves a linkage or fusion of two or more elements that have not been previously joined in just this fashion. This results in a qualitatively whole. The textbook further relates that all innovation

Managing Quality Performance in Supply Chains through Diffusion of Innovations Nadeem Kureshi Center for Advanced Studies in Engineering, Islamabad, Pakistan nadeemk@msu.edu 1. ABSTRACT Supplier Management is fast becoming one of the most critical determining factors in businesses as companies around the world are relying on outsourcing as a strategic tool to achieve competitive advantage. The growing trend of focusing on core competencies and letting the experts do their job has furthered the

How surface area affects the rate of diffusion. Hypothesis – the larger the surface area the faster the rate of reaction Why did you choose your hypothesis? The reason I have chosen my hypothesis is because large surface area of the tea bag will contain more molecules which means the rate of reaction will happen faster. For example the pyramid due to it 3D shape provides more sides for diffusion to take place and more area in the middle for the tea molecules to move around which will make

Communication Barriers to Applying Federal Research in Support of Land Management in the United States Vita Wright1 Abstract Barriers to effective communication between researchers and managers can ultimately result in barriers to the application of scientific knowledge and technology for land management. Both individual and organizational barriers are important in terms of how they affect the first three stages of the innovation-decision process: (1) knowledge, where an individual is exposed to innovation

The two most important scientific journals that publish theoretical work on Innovation Systems: The two most important scientific papers are research policy with 330 published articles about innovation systems and technological forecasting and social change with 364 published articles on innovation systems. These two journals have the most articles published on Innovation systems and the biggest journal impact factor. The 3 most cited papers that cite the paper by Malerba, and their main
