Exploration of Location-Based Services Adoption
2011
The purpose of this chapter is to explore aspects of user perceptions of their use of location-based services. As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This study begins by constructing a location-based service prototype simulation. It then conducts an experiment and analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model. A survey was developed to extract usage information from participants, followed by an analysis of the results using PLS. The analysis shows significant indicators that suggest …
Universal Design of ICT for Emergency Management from Stakeholders’ Perspective
2020
While Universal Design principles have been adopted in many areas to ensure that products and services are usable for the broadest possible diversity of users, there is still an open area when it comes to the emergency management domain. This article aims at providing a systematic overview of the current state of the emerging research field of Universal Design of Information and Communication Technology (ICT) for Emergency Management, and to highlight high-impact research opportunities to ensure that the increasing introduction of ICT in Emergency Management can contribute to removing barriers instead of adding more barriers, in particular for the elderly and people with disabilities. A sys…
Verbal and visual representations in task redesign: how different viewpoints enter into information systems design discussions
2005
We explore an important phase of information systems design (ISD), namely task redesign, and especially how different viewpoints enter into the dis- cussions. We study how one particular visual representation, a process diagram, is interpreted and how alternative, even competing, representations are produced verbally. To tie the visual and verbal representations and the representational prac- tices to wider social practices, we develop and use the Extended Three-dimen- sional Model of discourse. Visual representations emerged as focal in bringing in the different viewpoints and as reference points for discussions. Our model pro- vided a focused and powerful means to unveil for the outside r…
Information quality life cycle in secondary use of EHR data
2021
Abstract The paper argues that existing research on information quality (IQ) mainly focuses on the primary use of electronic health record (EHR) data, whereas IQ in secondary use of EHR data needs further deliberation. The current view of IQ in a healthcare context is static. It assumes that once the EHR system generates the information product, individual users may act on the information based on their subjective perception of its quality. However, this view ignores the complexities of secondary use of EHR data, in which users are actively involved in (re)generating and communicating the information product. Thus, IQ does not remain static but keeps on transforming through active engagemen…
Understanding the role of ICT and study circles in enabling economic opportunities: Lessons learned from an educational project in Kenya
2019
In this paper, we explore how the combination of Informa-tion and Communication Technologies (ICT) and self-organised study circles improves rural communities' abilityto enhance their economic oppo ...
Enabling a culture for IT services; the role of the IT infrastructure library
2016
Building on process management and service climate theories, this paper investigates the pertinent issues of whether firms that implement ITIL best practices for IT service management will also experience growth in their process management activities and IT service climate. First, ITIL practices imply that processes in the IT department should be managed on a daily basis; without process management, ITIL will fail beyond its initial implementation. Second, two of the main reasons for adopting ITIL are to become a service-oriented organisation and to deliver IT services that meet business needs. Thus, we hypothesise that as the implementation status of ITIL increases, process management and …
Human capital evaluation in knowledge-based organizations based on big data analytics
2020
Abstract Starting from a Human Capital Analysis Model, this work introduces an original methodology for evaluating the performance of employees. The proposed architecture, particularly well suited to the special needs of knowledge-based organizations, is articulated into a framework able to manage cases where data is missing and an adaptive scoring algorithm takes into account seniority, performance, and performance evolution trends, allowing employee evaluation over longer periods. We developed a flexible software tool that gathers data from organizations in an automatic way – through adapted connectors – and generates abundant results on the measurement and distribution of employees’ perf…
Facilitating Collaboration
2017
This article explores the potential synergy between computer-supported collaborative learning (CSCL) and collaboration engineering (CE). Both areas pursue the goal of understanding how to manage interactions in collaborative groups to achieve shared understanding, reduce process losses, and improve performance. By analyzing the research in the two areas, the authors identify several topics where exchange of research findings would be of mutual benefit. For example, research on CE can inform collaboration script research on reducing learners' cognitive load, providing sufficient guidance on the use of tools, and specifying the instructor role during the collaborative learning process. Simila…
Uncertainties and Risks in the Implementation of an E-Learning Information Systems Project in a Higher-Learning Environment: Viewpoints from Estonia
2005
This paper investigates the sorts of risks and uncertainties inherent in implementing an e-learning information systems project in Estonia. The study uses a variation of the Delphi study in eliciting the risk factors or items from experienced top management professionals within the organisation. The main objective of the study is to identify the uncertainties or risks in the implementation of the systems, using the viewpoint of Estonia, which is an emerging economy. The findings of the work indicate that wrong development strategy, staff volatility, change in top management and lack of funding are amongst the top risk factors in implementing e-learning in Estonia. On the other hand, risks …
Raising Energy Saving Awareness Through Educational Software
2013
A study that I have conducted on a sample of 395 children aged 6 to 12, from both the urban and the rural environments, shows that an increasing number of them use computer related technologies. Today there are an increasing number of web sites that inform the user of different ways to save energy and to reduce energy consumption because it is only natural that the modern information society would go online to research such topics. The development of an educational application that is focused on teaching the children about energy saving is represented on a timeline. We conducted a study in which a number of 29 children, aged between 8 and 10, use this educational application and a questionn…
