In this paper we study the topology effects on diffusion process in signed networks. Considering a simple threshold model for diffusion process, it is extended to signed networks and some appropriate definitions are proposed. This model is a basic model that could be extended and applied in analyzing dynamics of many real phenomena such as opinion forming or innovation diffusion in social netwo...

Received: 28 November 2005 Revised: 7 July 2006 Accepted: 16 October 2006 Abstract Grounded in the diffusion of innovation theory and the technology– organization–environment framework, we develop an integrative model to study the determinants of post-adoption stages of innovation diffusion, using enterprise digital transformation as an example of technology-enabled innovations. We specify four...

This paper describes a study that focused on long-term web-supported learning diffusion among lecturers at Tel Aviv University (TAU), from an organizational point of view. The theoretical models we used to examine this process are Rogers' model for "Diffusion of Innovation" (1995) and Bass's "Diffusion Model" (1969). The study was conducted between the academic years 2000/01 and 2007/08. At tha...

There is substantial research in the area of diffusion of innovation theory (DoI), and its application to information systems and information technology (IS/IT) innovation within organisations. However, scholars in recognition of the conceptual limitations of DoI, have called for the incorporation of certain aspects of social network theory (SNT) into DoI framework. In developing countries, one...

Purpose – We treat offshoring as a managerial innovation. Should it still be considered an innovation? The purpose of this paper is to use innovation theory, especially, Rogers’ diffusion of innovation theory (DOI) to examine this question. Design/methodology/approach – The paper examines the case of electronic data systems (EDS), a very large Information Technology Professional Services (ITPS)...

This article is about the diffusion of the Internet, an ICT innovation, in a sub-urban community in Malaysia. Introduced as a university service and then expanded by the Prime Minister’s department, the internet was chosen to show how an ICT innovation diffused in a sub-urban community, in a country where the government plays a major role in promoting the use of the internet through various ini...
