Elaborating the WARE Method for eParticipation Requirements
2010
Published version of a chapter in the book Information Systems Developement, 2010, 785-792. Also available from the publisher at: http://dx.doi.org/10.1007/b137171_82 eParticipation systems are often directly targeted at citizens. However, as a group of potential users, citizens form a heterogeneous and unpredictable group, which makes requirements elicitation a challenging issue. Based on recently developed ideas for wide audience requirement engineering (WARE), this chapter discusses and elaborates a method for eliciting citizen requirements for eParticipation. The method elaboration was conducted in connection with a project in southern Norway, where young people’s requirements for becom…
Implementation of a PLC Field Analyzer on a G3 Modem Platform
2021
Nowadays, power line communications (PLC) are a widely used technology in distribution grids, both for automatic meter reading and automation applications. PLC performances (in terms of capacity, coverage, robustness, and data transmission rate) can be significantly affected by electrical network topologies, connected loads and disturbances. Thus, utilities and modem manufacturers are increasing their interest in electrical network characterization. In this framework, a software tool is proposed in this paper to measure received signal and noise levels. As case study, it is implemented on a G3 PLC transceiver, widely used for smart metering purposes. In this way, a PLC channel characterizat…
Understanding TwitterTM Use among Parliament Representatives: A Genre Analysis
2011
Published version of a chapter published in the book: Electronic Participation. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-23333-3_1 This article examines parliament representatives’ Twitter- contributions (tweets). First, the genre of communication approach is introduced to identify common characteristics and communication patterns. Second, the findings are analysed using various eDemocracy models and deliberative standards to identify to what extent these tweets could be characterized as part of a deliberative discussion. The tweets are mainly dominated by five communication purposes; providing links to information sources for other Twitter users, to inform …
Genres of participation in social networking systems: A study of the 2009 Norwegian parliamentary election
2010
Published version of a chapter in the book: Electronic Participation. Also available at http://dx.doi.org/10.1007/978-3-642-15158-3_9 In the Norwegian context, eParticipation in the form of online campaigning has been on the agenda since 2001. After Obama’s successful presidential campaign in 2008, expectations about the use of SNS in the Norwegian parliamentary election were high. This study explores genres of participation in the early stages of the 2009 Norwegian parliamentary election campaign. The main finding is that the political parties have seen the need for a presence in SNS’, and that a genre repertoire for political communication through SNS is beginning to evolve. However, ther…
Experimental Evaluation on Narrow Band Power Line Communication in Medium and Low Voltage Smart Grids
2013
The aim of this work is to perform a feasibility study on the power line communication for the development of a new generation of interface devices (IDs) for smart grid and energy storage applications. More in detail, this paper deals with one of the most important issues on this topic, which is the communication system. Among the existing communication technologies, the study is focused on power line communications (PLCs). After an analysis of the state of the art in the field, the main aspects are analyzed, concerning the open issues on the use of PLCs, especially for medium voltage (MV) and low voltage (LV) systems. In this work the use of PLC in MV-LV networks is investigated, by means …
Internet-based information and foreign direct investment (FDI) location decision making: An information cost perspective
2012
Published version of an article in the journal: African Journal of Business Management. Also available from the publisher at: http://dx.doi.org/10.5897/AJBM11.1203 Open Access Information and communication technology (ICT) is considered to play an important role to reduce information cost for potential foreign investors. While a growing body of literature has suggested such connections, conceptual clarity is yet to be achieved. This study introduces a conceptual framework based on the Information-theoretic approach and transaction cost perspective to explore how ICT may reduce information cost. To illustrate our proposed framework, we apply it to examine the role of Internet-based informati…
Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…
Perceived support in e-collaborative learning: An exploratory study which make use of synchronous and asynchronous online-teaching approaches
2012
Published version of a chapter in the book: Advances in Web-Based Learning - ICWL 2012. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33642-3_2 This study compares four different learning environments for e-collaborative learning in two European countries related to the dimension of student’s mutual support. The theoretical baseline is Vygotsky’s zone of proximal development (ZOPD) and the socio-genetic approach of Piaget. The analyzed data are based on questionnaires collected over the time period of an entire semester including four different courses at the master’s level. These courses applied different e-collaborative approaches including a variety of tools f…
The Genre System Lens on E-Democracy
2008
Published version of an article published in Scandinavian Journal of Information Systems, 20 (2), 51-82. Also available from the publisher at: http://aisel.aisnet.org/sjis/vol20/iss2/3 E-Democracy aims at enhancing citizen involvement in societal communication and decision making. However, the very ideals of democracy vary while reports of e-democracy in use have often left them undiscussed. Moreover, theoretical works on the potential of information technology (IT) for democratization have often viewed IT as a “black box”, and assumed that technology should create an impact as such. Hence, there is a dearth of research on the interplay between models of e-democracy and actual IT artefacts …
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…
