E-Government in Marketing a Country: A Strategy for Reducing Transaction Cost of Doing Business in Tanzania
2011
Published version of an article in International Journal of Marketing Studies, 3(4), 2-16. Also available from the publisher at http://dx.doi.org/10.5539/ijms.v3n4p2 There are limited studies examining the role of Investment Promotion Agencies (IPA’s) and their respective marketing techniques used in attracting Foreign Direct Investment (FDI). Using an exploratory case study approach, this article addresses this research gap by exploring the role of e-government as a promotion technique in eliminating barriers to FDI inflows in Tanzania; particularly barriers related to information accessibility and bureaucratic procedures facing foreign investors in acquiring relevant licenses and business…
Defining the IT artefact in social media for eparticipation: An ensemble view
2012
Published version of a paper from the European Confernece on Information Systems. Also available from the publisher: http://aisel.aisnet.org/ecis2012/175 Social media has become a popular outlet for various eParticipation activities, such as online campaigning by political parties. However, research so far has shown that political parties often have limited success with their efforts. Much is yet unclear as to the results and possible applications of social media use. This paper contributes to clarify the underlying concepts of social media, by analysing the social media IT artefact as a socio-technical object. We propose and define an ensemble view on social media use in eParticipation, an…
The support for different democracy models by the use of a web-based discussionboard
2004
Published version of a chapter published in Lecture Notes in Computer Science, 3183, 23-26. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-540-30078-6_4 Different initiatives are initiated to utilize ICT to maintain and develop democracy. Democracy models are developed to explain differences between different democracies. This paper reports from a case study where a web-based discussion board is developed and implemented. The findings indicate that politicians and citizens add support to different democracy models by their contributions to the web-based discussion board. Contributions from the citizens add stronger support for the neo-republican model where as politic…
Democracy Squared: Designing On-Line Political Communities to Accommodate Conflicting Interests
2005
Published version of an article published in Scandinavian Journal of Information Systems, 17 (2), 133-168. Also available from the publisher at: http://aisel.aisnet.org/sjis/vol17/iss2/5. On-line political communities, such as the Norwegian site Demokratitorget (Democracy Square), are often designed according to a set of un-reflected assumptions about the political interests of their potential members. In political science, democracy is not taken as given in this way, but can be represented by different models which characterize different relationships between politicians and the citizens they represent. This paper uses quantitative and qualitative content analysis to analyze the communicat…
Social media as public sphere : an exploratory study of online political communication in Norway
2013
Doctoral dissertation, Faculty of Economics and Social Sciences, University of Agder, Kristiansand 2013 This thesis presents an exploratory study of the use of social media in the Norwegian public sector, and contributes to the understanding of how social media can be applied to improve deliberation. The study is situated within the eParticipation research field. The motivation for the study is the reported challenges facing democracy, in the form of lower voter turnout, decline in political party membership, and a general lessening of interest for public issues and deliberation. Deliberation is seen as essential for democracy, and promoting deliberation could well lead to an increase in vo…
Why Benefits Realization from ERP in SMEs Doesn't Seem to Matter?
2011
Author's version of a chapter in Proceedings of the 44th Hawaii International Conference on System Sciences. Also available from the publisher: http://dx.doi.org/10.1109/HICSS.2011.497 It is often argued that IT investments require active management practices for benefits realization. This applies also to enterprise resource planning (ERP) systems. As well, benefits realization efforts are assumed to create more value than they cost. Hence, the maturity of organizations should be increased and their cultures cultivated towards more rational benefits realization practices. Our study on ERP implementations in Egyptian medium-sized organizations, however, provides aberrant results that challen…
On the evolution of e-Government: The user imperative
2003
Published version of a chapter published in Lecture Notes in Computer Science, 2739, 139-143. Also available from the publisher at: http://dx.doi.org/10.1007/10929179_25 This paper focuses the need for more research on user involvement and the investigation of stakeholders in e-Government initiatives. An investigation of existing work revealed a lack of research on those topics. As e-Government evolves and users mature, the value of their input can increase. The paper discusses the need and potential benefits of this approach. Finally, we suggest that existing stakeholder theory is investigated for adaptation into e-Government settings in order to map the complex body of interrelated stakeh…
HINTS: A novel approach for realistic simulations of vehicular communications
2012
One of the main challenges in the Vehicular Ad-Hoc Networks (VANETs) research domain is the simulation of vehicular communications using realistic mobility models. Several efforts have been put lately in this purpose; yet, the proposed models are either inappropriate, or carry significant disadvantages. In this paper, we propose a novel approach for realistic simulations in vehicular networks, inspired from the hierarchical video and image compression technique. We developed HINTS (Hybrid Integration of Network and Traffic Simulators), the correspondent platform, engendered from the integration of SUMO, a traffic simulator and NS-3, a network simulator after adding some supplemental modules…
A Non-WSSUS Mobile-to-Mobile Channel Model Assuming Velocity Variations of the Mobile Stations
2017
This paper aims to characterize the effects that the velocity variations of the mobile stations (MSs) produce on the correlation properties of non-stationary time-frequency (TF) dispersive mobile- to-mobile (M2M) fading channels. Toward that end, we propose a novel geometrical model for non-wide-sense stationary uncorrelated scattering (non-WSSUS) M2M channels that incorporates such variations following a plane wave propagation approach. Capitalizing on the mathematical simplicity of this approach, we derive a general expression for the four-dimensional (4D) TF correlation function (TFCF) of the proposed channel model. From this expression, we analyze the influence of the MSs' acceleration#…
Metacommunication Patterns in Online Communities
2009
Published version of a chapter in the book: Online Communities and Social Computing. Also available from the publisher at http://dx.doi.org/10.1007/978-3-642-02774-1_26 This paper discusses about contemporary literature on computer-mediated metacommunication and observes the phenomenon in two online communities. The results contribute by identifying six general-level patterns of how metacommunication refers to primary communication in online communities. A task-oriented, user-administrated, community (Wikipedia in Finnish) involved a remarkable number of specialized metacommunication genres. In a centrally moderated discussion-oriented community (Patientslikeme), metacommunication was inter…
