Stakeholders, contradictions and salience: An empirical study of a Norwegian G2G effort
2006
Author's version of a chapter in Proceedings of the 39th Annual Hawaii International Conference on Systems Sciences. Also available from the publisher at http://dx.doi.org/10.1109/HICSS.2006.436 Previous studies indicate that the expected effects of e-Government are slower to realize than initially expected. Several authors argue that e-Government involves particularly complex settings, consisting of a variety of stakeholders promoting different and often conflicting objectives. Yet, few studies have explicitly addressed the inherent challenges of this complexity. This study focuses on the extent to which contradictory stakeholder objectives can help explain the relatively slow progress of …
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…
Access Security and Personal Privacy in Public Cellular Communication Systems: The Past, the Present and Beyond 2020
2010
In order to predict the future one needs to understand the past and then interpolate as best as possible. We expect this to work reasonably well for a “2020 Scenario”, but we do not expect this approach to be valid for a “Beyond 2020” scenario.
The role of social networking services in eParticipation
2009
Published version of a chapter published in Lecture Notes in Computer Science, 5694, 46-55. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-03781-8_5 A serious problem in eParticipation projects is citizen engagement – citizens do not necessarily become more willing to participate simply because net-services are provided for them. Most forms of eParticipation in democratic contexts are, however, dependent on citizen engagement, interaction and social networking because democratic systems favour the interests of larger groups of citizens – the more voices behind a political proposition, the greater its chances of success. In this context of challenges the study of s…
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…
Business Intelligence uten et tradisjonel datavarehus
2013
Masteroppgave i informasjonssystemer - Universitetet i Agder 2013 Denne masteroppgaven ser på bruken av en «Business Intelligence» (BI)-løsning uten et tradisjonelt datavarehus. Litteraturen forutsetter i stor grad et datavarehus for vellykket BI, men til tross for dette velger noen bedrifter å utelate datavarehuset fordi det medfører en høy risiko og betydelige kostnader knyttet til implementasjonen. Rapporten har sett på om utelatelsen av et datavarehus er en akseptabel løsning for en bedrift som ønsker beslutningsstøtte. For å svare på dette har jeg gjennomført en casestudie i Boen, en internasjonal aktør i parkettbransjen. Boen valgte å implementere en BI-løsning våren 2013 uten å benyt…
Implementing Intranet 2.0: A Study of Knowledge Requirements for External Consultants in Enterprise Systems
2014
Published article from the series: Procedia Technology. Also available on Science Direct: http://dx.doi.org/10.1016/j.protcy.2014.10.018 Open Access This paper reports on a case study focusing on intranet implementation projects seen from a consultancy lens. SharePoint is an Intranet 2.0 platform which is a user-centric system based on functionalities adapted from Web 2.0 technologies. Intranet implementation projects are accompanied by a complex socio-technical organizational environment, and require changes in organizational structure and culture. While former studies mainly have focused on challenges seen from the implementing organization's perspective, this study focuses on the experie…
Measurement Issues for the Characterization of Medium Voltage Grids Communications
2013
This paper is focused on the measurement issues and procedures for the characterization of medium voltage grids for narrowband power line communications (NB-PLCs), in the perspective of the use and integration of such technology into smart grids communication networks. The fundamentals are given for the characterization of the PLC channel, by means of noise and attenuation measurements. Suitable procedures are also developed for the characterization and modeling of the power system components in the frequency range of interest. Furthermore, the complete model of the PLC system is experimentally validated in a real case study.
Sosiale medier i offentlig sektor : fra et gevinstrealiseringsperspektiv
2013
Masteroppgave i informasjonssystemer - Universitetet i Agder 2013 Brukerne av sosiale medier er mange, deriblant naturligvis også innbyggere. Forskere og litteratur peker ofte på viktigheten med å involvere innbyggere i den offentlige forvaltning. Her er det store rom for sosiale medier. Forskningsspørsmålet for oppgaven er: «Hvilke gevinster kan oppnås ved bruk av sosiale medier i det offentlige? Og hvordan kan slike gevinster realiseres?» Offentlige etater har i stor grad vanskeligheter (store utfordringer) med å utnytte teknologi, realisere mål og oppnå gevinster. Mulighetene og potensialet med sosiale medier er og blir i liten grad realisert, særlig innenfor den offentlige forvaltning. …
Treating cockroach phobia using a serious game on a mobile phone and augmented reality exposure: A single case study
2011
In vivo exposure has proved its efficacy in the treatment of specific phobias; however, not all patients benefit from it. Communication and information technologies such as Virtual Reality (VR) and Augmented Reality (AR) have improved exposure treatment adherence and acceptance. Serious games (SG) could also be used in order to facilitate exposure treatment. A line of research on SG is emerging which focuses on health issues. We have developed a SG for the treatment of cockroach phobia that uses a mobile phone as the application device. This work examines results of an N = 1 study about whether the use of this mobile game can facilitate treatment of this specific phobia preparing her for th…
