“…Using logistic and Gompertz diffusion curves estimated using nonlinear least squares, [11] identified the determinants of mobile diffusion in the study countries. Reference [12] examined mobile diffusion in Portugal and found that mobile penetration rates followed an s-curve, in particular, a logistic curve.…”

Most countries have allocated 3G spectrum and are in the process of allocating advanced wireless services and 4G spectrum, both of which promise subscribers significantly faster broadband speeds. Operators anticipate that subscribers will adopt these services swiftly thereby justifying the large investments. Yet, why is it the case that only two countries in the world have more 3G than 2G subscribers? This study examines the drivers behind 3G diffusion using linear probability models and qualitative choice (logit) analysis. Time series diffusion models show that diffusion patterns follow an s-curve pattern, favoring the Gompertz curve.

“…As mobile communications have experienced significant development during recent years, a considerable volume of research has been carried out with particular emphasis on their diffusion at national (Botelho & Pinto, 2004) as well as at international level (Fildes & Kumar, 2002;Gruber, 2005) Mobile services have faced rapid diffusion in Europe, as a result of technological change and governmental decisions and regulations, as well as competition at national level (Gruber, 2005). The study of the diffusion process of mobile services is of paramount importance in understanding the factors influencing further development of mobile networks towards the introduction of 3G/4G networks and the derived knowledge should be seriously taken into consideration for building appropriate strategic plans and for constructing the necessary supporting infrastructure.…”

This paper examines and presents the diffusion rate of mobile telephony subscriptions in Greece. Following the evaluation of the most widely used aggregate technology diffusion models (such as the Bass model, the Fisher-Pry model, the Gompertz models and some representatives of the logistic variants), it becomes evident that these S-shaped models are suitable enough for accurate fitting and forecasting the diffusion of mobile telephony. The analysis of the diffusion process in Greece provides some interesting aspects of mobile penetration such as the correlation between the diffusion speed and the number of competing operators as well as other socioeconomic and regulatory aspects. As a result of the estimation of 2G's diffusion process parameters, the potential market size and the analysis of the techniques for the appropriate model selection, this analysis can be considered as a means of providing an insight into the estimation of the diffusion shapes of the forthcoming generations of mobile telephony and telecommunication products and services in Greece and elsewhere. r

“I'd like to thank the academy”: An analysis of the awards discourse at the Atlantic Schools of Business Conference

The awarding of prizes has become embedded in all aspects of our society, including academic conferences. At the same time, the reputation economy, an economy where individual standing is based on the opinions of end users, is growing in strength and validity. We analyzed the way in which the awards discourse has been recontextualized within a small academic conference that is struggling to find legitimacy—the Atlantic Schools of Business Conference. With a focus on language and the different meanings words hold in different discourses, we have determined that recontextualization of the discourse within the conference has resulted in two distinct discourses—the discourse of the award giving body and the discourse of the potential award recipient.
