Design and Characterization of a New MV PLC Coupler for Smart Electric Energy Systems
2018
This paper deals with the design, modeling and characterization of a new coupling system for medium voltage (MV) narrow band power line communications (NB-PLC). It exploits the capacitive divider of voltage detecting systems (VDSs) normally used to reveal the mains voltage presence, thus avoiding the use of dedicated MV couplers. The proposed coupling system was patented by the authors. In this paper, the modeling of the VDS capacitive divider is presented, using a proper characterization method. Moreover, the interface card design is described, based on simulation of the whole PLC transmission channel. Laboratory tests are also presented and discussed. More in detail, a frequency response …
ERP systems in SMEs: A literature review
2011
Published version of a chapter in Proceedings of the 44th Hawaii International Conference on System Sciences. Also available from the publisher: http://doi.dx.org/10.1109/HICSS.2011.191 This review summarizes research on enterprise resource planning (ERP) systems in small and medium-size enterprises (SMEs). Due to the close-to-saturation of ERP adoptions in large enterprises (LEs), ERP vendors now focus more on SMEs. Moreover, because of globalization, partnerships, value networks, and the huge information flow across and within SMEs nowadays, more and more SMEs are adopting ERP systems. Risks of adoption rely on the fact that SMEs have limited resources and specific characteristics that ma…
Demystifying the Possibilities of ICT4D in the Mountain Regions of Nepal
2011
Author's version of a chapter in the book: Proceedings of the 44th Hawaii International Conference on System Sciences. Also available from the publisher at: http://dx.doi.org/10.1109/HICSS.2011.142 Despite the substantial investments in ICT4D projects in developing countries, the benefits are yet to be realised by the majority of remote communities. Inaccessibility to ICT has widened educational, healthcare, information, and communication gaps between urban and remote communities. This paper focuses on an interpretive case study in Nepal to widen our understanding of how locally-initiated ICT4D projects may help to narrow these gaps. The study utilises the Assets Pentagon Model to identify …
Towards a cumulative tradition in e-Government Research: Going beyond the Gs and Cs
2007
Published version of a chapter published in Lecture Notes in Computer Science, 4656, 13-22. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-540-74444-3_2 The emerging research area of e-Government is gradually moving towards a level of maturity on the back of increasingly rigorous empirical research. Yet, there has been little theoretical progress and a cumulative tradition is not emerging. We argue that a principle reason for this is a lack of shared understanding about basic concepts and entities amongst scholars in the field. Specifically, the entities that form the bedrock of e-Government research, such as “Government” and “Citizen” are conceptualized at a very gen…
Proposing an Entrepreneurial Process for the Co-creation of IT Value
2014
Published version of a chapter from the book M. Janssen, H. Scholl, M. Wimmer & F. Bannister (Eds.), Electronic Government : Springer Berlin Heidelberg, 2014. Also available on SpringerLink: http://dx.doi.org/10.1007/978-3-662-44426-9_26 Co-creation of IT value has received substantial focus from the IS research community over the past years. However, few if any have studied this phenomenon from a process perspective, and our understanding of the processes leading to successful co-creation is therefore limited. To address this shortcoming, we studied a complex, e-government case involving 38 government agencies intending to co-create value from a common IT platform. We used a mixed method a…
Assessing Effects of eGovernment Initiatives Based on a Public Value Framework
2012
Published version of a chapter in the book: Electronic Government. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33489-4_21 Assessing effects of eGovernment initiatives is considered an important but challenging endeavor. Assessments are, among other things, important to justify e-government investments. They are challenging because they are complex, often based on locally defined indicators, many times over-emphasizing financial effects, imprecise, faced with a number of contingencies and very seldom validated. Consequently, effect assessments can be seen as imprecise and difficult to compare across different initiatives. This paper addresses some of the challen…
Understanding the dynamics in e-Participation initiatives: Looking through the genre and stakeholder lenses
2011
Accepted version of an article published in the journal: Government Information Quarterly. Also available from the publisher at: http//dx.doi.org/10.1016/j.giq.2010.10.005 Conventionally, e-Participation initiatives are considered to be successful only if users use these services. While the growing body of e-Participation literature has listed and studied challenges and barriers to achieving this end, conceptual clarity on why such projects are considered as failures is yet to be achieved. We argue that this is due to the inadequate understanding of the complex stakeholder dynamics of an e-Participation project. In this paper, we seek to address this knowledge gap by proposing that using St…
Intervención terapéutica y coordinación familiar en los inicios comunicativos de un caso de atención temprana
2020
En este estudio de caso se aborda la intervención realizada en un centro de diagnóstico y atención temprana, a una alumna de dos años con hemiparesia lateral izquierda y dificultades en la manipulación y comunicación. Aplicando a lo largo de cuatro meses el sistema de Comunicación Total de Benson Schaeffer con el apoyo del método TEACCH, se pretende superar las graves limitaciones comunicativas de la alumna. El procedimiento metodológico utilizado es mixto y las técnicas de investigación empleadas son la aplicación de un test estandarizado, la entrevista, los registros de observación y el análisis documental. A partir del test cumplimentado por la madre que establece la evaluación inicial d…
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. …
Systemutviklingsrutiner : "motivasjon og forutsetning for videreføring av systemutviklingsrutiner" : en casestudie av en lokal avdeling i et større k…
2013
Masteroppgave i informasjonssystemer – Universitetet i Agder 2013 Bruken av metode i systemutvikling har lenge vært sett på som et viktig element for å kunne gjennomføre prosjekter raskt, strukturert, effektivt og forutsigbart. Noe som derimot har kommet frem rundt dette, er at nesten ingen bruker metoden helt slik den er tenkt og man ender opp med å gjøre tilpassninger. Videre forskning på hvorfor metoder fungerer eller ikke, er dermed problematisk ettersom alle bruker metodene forskjellig. Det jeg derfor har sett nærmere på, er i stedet rutiner og praksis. Studien har tatt for seg to rutiner i en lokal avdeling i et større konsulentselskap, med fokus på testrutine og rutine for smidig utv…
