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…

FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images

2019

Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…

Young People's Translocal New Media Uses: A Multiperspective Analysis Of Language Choice And Heteroglossia

2009

The aim of this paper is to shed light on the particularities of the linguistic, social and cultural action of young Finns in translocal new media spaces, and the ways in which they themselves make sense of and account for their actions. We present findings from 4 case studies, each of which illustrates aspects of translocality in young Finns' new media uses. Theoretically and methodologically the case studies draw on sociolinguistics, discourse studies, and ethnography, making use of the concepts of language choice and linguistic and stylistic heteroglossia. Through the 4 cases in focus, the paper shows how young people's linguistically and textually sophisticated new media uses are geared…
