    Research on ICT and development (ICTD) involves assumptions on the nature of ICT innovation and on the way such innovation contributes to development. In this article I review the multidisciplinary literature on ICTD and identify two perspectives regarding the nature of the ICT innovation process in developing countries - as transfer and diffusion and as socially embedded action - and two perspectives on the development transformation towards which ICT is understood to contribute - progressive transformation and disruptive transformation. I then discuss the four discourses formed by combining the perspectives on the nature of IS innovation and on the development transformation. My review suggests that ICTD research, despite its remarkable theoretical capabilities to study technology innovation in relation to socio-economic context, remains weak in forming convincing arguments on IT-enabled socio-economic development.

    Spatial diffusion of electric vehicles in the German metropolitan region of Stuttgart

    At the moment, interest in electric vehicles (EVs) is increasing worldwide, mainly due to concerns about climate change and rising prices of fossil fuels. EVs still have some significant drawbacks compared to gasoline-powered cars. However, a small part of the population is expected to adopt this technology already within the next years, because higher purchase costs and lower driving range are of less concern to them. They are called the “Early Adopters†of EVs. In this study we developed scenarios for the spatial diffusion of EVs up to 2020 in private households in the municipalities and urban districts of the metropolitan region of Stuttgart in Germany. First, hypotheses of Early Adopters of EVs were constructed based on social mobility profiles and the demands of car drivers. Secondly, the number of these potential adopters was calculated with statistical data for each municipality and urban district. In a third step, we developed a Bass diffusion model with System Dynamics to simulate the spatial diffusion of EVs in the region of Stuttgart. The increase of EV-ownership in each Early Adopter-type in a single municipality depends on the chosen values of the parameters “Advertisement effectivenessâ€, “Contact Rate†and “Adoption Fraction†of the Bass model. Furthermore, neighbourhood effects were modeled such that the increase of EVs in one municipality also depends on the increase of EVs in the neighbouring municipalities. In the baseline scenario, significant spatial differences in the diffusion of EVs up to 2020 become apparent: the highest number of EV-holders will be found in the urban areas of the region. There exist also differences in the number of EVs present at each Early Adopter-type: The “Urban trend-setter†is prevalent in the central districts of Stuttgart, while the “Multi-car family†is mostly located in the more rural municipalities of the region of Stuttgart. The “Dynamic senior citizen†is almost equally distributed in the urban and rural areas. The results of the spatial distribution of potential adopters of EVs can be used for the automobile industry’s marketing campaigns as well as to identify the regional demand for EV charging infrastructure.

    Theorization and translation in information technology institutionalization: evidence from Danish home care

    Although institutional theory has become a more dominant perspective in information systems research, studies have only paid scant attention to how field dynamics and organizational processes coevolve during information technology institutionalization. Against this backdrop, we present a new conceptualization based on the “traveling of ideas” metaphor that distinguishes between theorization of ideas about IT usage across an organizational field and translation of such ideas into practical use of IT within particular organizations. Drawing on these distinct analytical views, we posit that IT institutionalization is constituted through recursive intertwining of theorization and translation involving both linguistic and material objects. To illustrate the detailed workings of this conceptualization, we apply it to a longitudinal study of mobile IT institutionalization within Danish home care. We demonstrate how heterogeneous actors within the Danish home care field theorized ideas about mobile IT usage and how these ideas translated into different local arrangements. Further, our account reveals a complex institutionalization process in which mobile IT was first seen as a fashionable recipe for improvement but subsequently became the subject of controversy. The paper adds to the emerging process and discourse literature on IT institutionalization by shedding new light on how IT ideas travel across a field and within individual organizations, how they transform and become legitimized over time, and how they take on different linguistic and material forms across organizational settings

    The Local Emergence and Global Diffusion of Research Technologies: An Exploration of Patterns of Network Formation

    Grasping the fruits of "emerging technologies" is an objective of many government priority programs in a knowledge-based and globalizing economy. We use the publication records (in the Science Citation Index) of two emerging technologies to study the mechanisms of diffusion in the case of two innovation trajectories: small interference RNA (siRNA) and nano-crystalline solar cells (NCSC). Methods for analyzing and visualizing geographical and cognitive diffusion are specified as indicators of different dynamics. Geographical diffusion is illustrated with overlays to Google Maps; cognitive diffusion is mapped using an overlay to a map based on the ISI Subject Categories. The evolving geographical networks show both preferential attachment and small-world characteristics. The strength of preferential attachment decreases over time, while the network evolves into an oligopolistic control structure with small-world characteristics. The transition from disciplinary-oriented ("mode-1") to transfer-oriented ("mode-2") research is suggested as the crucial difference in explaining the different rates of diffusion between siRNA and NCSC

    ICT adoption in developing countries : perspectives from small-scale agribusinesses

    Get PDF
    The purpose of this paper is to critically examine how social augmented parameters impact on the effective adoption of information and communication technology (ICT) by small-scale agribusinesses operating in Southeast Nigeria. The relevance of incorporating social imperatives in scholarship focused on technology adoption is due to its role in sustaining the process of adoption and diffusion. Data were gathered from a focus group made up of 27 agribusiness proprietors affiliated with a state cooperative based in the south-eastern Nigerian state of Ebonyi. This paper puts forward an argument that to ensure successful diffusion of innovation, a balance must be maintained between the amount of effort expended in the design of ICT and social factors such as language and traditional life. The paper finds that a willingness of indigenous ICT users is particularly influenced by the recognition and incorporation of visible social imperatives during the adoption process. The outcome of this study highlights important issues for ICT adoption. One particular area that must be taken into consideration is the adoption channel. Perceptions of ICT adoption will differ significantly among adopters. For this reason, the need for developing an appropriate adoption channel that ensures successful diffusion of the innovation should be recognised. This study contributes to ongoing research in ICT innovation adoption in small agribusinesses operating in indigenous societies. The theoretical implications of this paper are the development of a conceptual ICT adoption framework that emphasises social imperatives. The paper also demonstrates that agricultural enterprises should be treated as ‘normal’ firms in their own right

    Electronic administration in Spain: from its beginnings to the present

    Get PDF
    This study presents the basic lines of electronic administration in Spain. The complexity of the Spanish political-administrative system makes such a study challenging, in view of the considerable degree of autonomy and competences of the regional administrative bodies and local agencies with respect to the central government, the former being more visible in the 17 regions of Spain. Nonetheless, the central government maintains a series of legal instruments that allow a certain common framework of action to be imposed, aside from what is put into effect through diverse programs aimed precisely to develop common tools for the regions and municipalities of Spain. After an introduction that provides some necessary background, this study describes the legislative framework in which Spain's electronic administrative system has developed. The data included in the study refer to investment in information and communication technologies (ICT) and the services offered by the different Administrations on the internet; internet access by citizens, homes, businesses, and employees, as well as the interactivity existing with administrations by means of the internet; the origins and rise of various political initiatives of the Central Government involving electronic administration; and finally, the situation of civil service personnel, as catalysts of the success of Information Society in the Public Administration within Spain
