Roll Out

Building on Rogers’ Diffusion of Innovation Theory, Bass models describe the diffusion processes distinguishing between innovation (p) and imitation (q). This study aimed at modelling the uptake of RIS, PACS and EHR systems in Germany and Finland. The Bass models revealed a quick and almost identical uptake process across all three systems for Finland. In contrast, the Bass models mirrored a slower uptake in Germany. Consequently, the Finnish “imitation” coefficients were larger than the German ones. While in Germany almost free market forces were driving the adoption through imitation but without tail wind from policy, the adoption process in Finland was centrally governed. This suggests that the diffusion process in Finland reflected a well-managed roll-out of the systems rather than imitation behaviour. Thus, in order for Bass model coefficients to be understood properly, additional contextual information is required.

Research Questions

Purpose was to examine how mass adoption of 3DTV in the United States as the next major step in TV evolution could take place, after the technology recently failed in the 2010s. Answers to the research questions focused on understanding what conditions for mass adoptions would need to exist and how the National Football League TV transmissions could support the adoption process until when. An integrated literature review defined inhibiting factors to adoption related to technology, health, content, marketing strategy and price. Solution paths were proposed. Rogers’ diffusion of innovation theory and the Bass model were applied in a comparatist perspective, comparing 3DTV to historical adoption pat-terns of both HDTV and color TV. The comparatist approach proved to be very useful, as forecast models ignoring historical adoption patterns usually failed. Findings revealed that most American households could possess 3DTV sets by 2032, if Avatar sequels would kick off another cycle of 3D cinema, followed by 3DTV re-introduction. NFL TV transmissions were found to be perhaps the single most important factor to motivate Americans buying 3DTV sets and supporting mass adoption. The study encountered limitations, related to the Bass model. Also, findings from the American market would need to be adapted carefully to situations in other countries, before generalizing them.

Digital Terrestrial Television

This study aims at finding out if households or organizations are faster in their acceptance of a technological innovation. The object of this study is digital terrestrial television (DTT), specifically the implementation of DTT in Denmark. The theoretical framework is diffusion of innovation theory. Three surveys were carried out for both households and organizations. Based on the surveys, the rate of adoption for households and for organizations could be established. It is clear that organizations accept new technology faster than households during the entire adoption process. An explanation may be that it is the employees in the organization who are the most open to technology innovations who set the agenda for the acceptance process. Danish culture can have had an influence on the findings. If that is the case the findings may be generalizable only to cultures that are similar to Danish culture.

Social Innovations

While originally utilized within the natural and agricultural sciences, the diffusion of innovation theory has been applied across numerous contexts. As we continue to apply this model within Extension education, international development, and other community education contexts around the world, it not only becomes pertinent to examine how it applies towards social innovations – innovations that improve the social good – but also to understand how communities react when adopting social innovations. Within this article, researchers propose an Emotional-Behavioral Influence Model to deepen the understanding as to how communities respond, emotionally and behaviorally, towards social innovations throughout the adoption process. They then overlay the model onto two examples, one urban and one rural, showcasing its application to communities worldwide. Finally, researchers discuss implications for extension professionals as they preflect on implementing social innovations in communities globally.

Diffusion Of Innovation Theory

The purpose of this article is to examine whether the use of open educational resources (OER) in teacher preparation programs impacts the perception of the resource. P-12 schools are beginning to adopt OER; however, many teachers are unfamiliar with OER, which may slow diffusion throughout the institution. In this study, two groups of teacher candidates from two universities completed surveys evaluating their perceptions of OER. The first group used an open textbook in their course. The second group had no experience using OER. Results indicate that teacher candidates who used the open textbook perceived OER more positively and were more likely to want to use OER in their future classrooms. The results suggest that incorporating OER into courses during teacher preparation programs not only better prepares teacher candidates for using the resources after graduation, but also increases progression through the adoption process described in the diffusion of innovation theory.

Initial Settings

Once a health promotion program has proven to be effective in one or two initial settings, attempts may be made to transfer the program to new settings. One way to conceptualize the transference of health promotion programs from one locale to another is by considering the programs to be innovations that are being diffused. In this way, diffusion of innovation theory can be applied to guide the process of program transference. This article reports on the development of six questionnaires to measure the extent to which health promotion programs are successfully disseminated: Organizational Climate, Awareness-Concern, Rogers's Adoption Variables, Level of Use, Level of Success, and Level of Institutionalization. The instruments are being successfully used in a study of the diffusion of health promotion/tobacco prevention curricula to junior high schools in North Carolina. The instruments, which measure the four steps of the diffusion process, have construct validity since they were develóped within existing theories and are derived from the work of previous researchers. No previous research has attempted to use instruments like these to measure sequentially the stages of the diffusion process.

Purpose This paper aims to review previous studies on how organizations, particularly small and medium enterprises (SMEs), adopt digital information and technology, especially on the drivers and the outcomes of the adoption itself. Design/methodology/approach The present study follows a literature review design. Previous studies that examine SMEs’ digital information and technology adoption are taken into account in building the conclusion. Findings The review reveals that digital information and technology that is used for marketing-related position allows SMEs to be more competitive. In general, there are three main theories that have been used to understand the adoption process (i.e. diffusion of innovation theory, technology-organization-environment framework and institutional theory). These theories should be used in conjunction with each other to better explain the adoption process. Additionally, there are three characteristics (i.e. innovation, firm and environmental) that are related to the risks and barriers of the adoption process. Originality/value This theoretical review is among the few that put forward the findings reported in research articles on the digital information and technology adoption process within SMEs. Moreover, this paper summarizes the issues (i.e. drivers, outcomes, risks and barriers) related to the adoption process.

This article offers insight into the role of the state in land financialisation through a reading of urban hegemony. This offers the basis for a conjunctural analysis of the politics of planning within a context in which authoritarian neoliberalism is ascendant across Europe. I explore this through the case of Antwerp as it underwent a hegemonic shift in which the nationalist neoliberal party the New Flemish Alliance (Nieuw-Vlaamse Alliantie; N-VA) ended 70 years of Socialist Party rule and deregulated the city’s technocratic planning system. However, this unbridling of the free market has led to the creation of high-margin investment products rather than suitable housing for the middle classes, raising concerns about the city’s gentrification strategy. The consequent, politicisation of the city’s planning system led to controversy over clientelism which threatened to undermine the N-VA’s wider hegemonic project. In response, the city has sought to roll out a more formalised system of negotiated developer obligations, so embedding transactional, market-oriented informal governance networks at the centre of the planning system. This article highlights how the literature on land financialisation may incorporate conjunctural analysis, in the process situating recent trends towards the use of land value capture mechanisms within the contradictions and statecraft of contemporary neoliberal urbanism.

We consider surface measures on the set of trajectories in a smooth compact Riemannian submanifold of Euclidean space generated by diffusion processes in the ambient space. A construction of surface measures on the path space of a smooth compact Riemannian submanifold of Euclidean space was introduced by Smolyanov and Weizsäcker for the case of the standard Brownian motion. The result presented in this paper extends the result of Smolyanov and Weizsäcker to the case when we consider measures generated by diffusion processes in the ambient space with nonidentical correlation operators. For every partition of the time interval, we consider the marginal distribution of the diffusion process in the ambient space under the condition that it visits the manifold at all times of the partition, when the mesh of the partition tends to zero. We prove the existence of some limit surface measures and the equivalence of the above measures to the distribution of some diffusion process on the manifold.

Abstract We study a problem when the optimal stopping for a one-dimensional diffusion process is generated by a threshold strategy. Namely, we give necessary and sufficient conditions (on the diffusion process and the payoff function) under which a stopping set has a threshold structure.
