Diffusion versus recrystallization processes in Rb–Sr geochronology: Isotopic relics in eclogite facies rocks, Western Gneiss Region, Norway

2008

Abstract Rb–Sr and U–Pb isotopic data for granulite facies rocks, forming textural relics with respect to eclogite facies metamorphism in the Western Gneiss Region (WGR) of Norway, highlight the importance of textures and mineral reaction kinetics for the interpretation of geochronological data. Studied rocks from Bardsholmen, southern WGR, were subjected to granulite facies metamorphism at 955 ± 3 Ma (U–Pb, zircon). Later on, they experienced a subduction-related, kinetically stranded eclogitization ( T  > 650 °C at ∼20 kbar) at 404 ± 2 Ma (Rb–Sr multimineral internal isochron data), followed by exhumation through amphibolite facies conditions. Full conversion of granulite to eclogite was …

La grotte de l'Eremita au Monte Fenera (Vercelli, Italie) : nouvelles découvertes du Bronze moyen

2014

Située au coeur du massif calcaire du Monte Fenera dans le Piémont italien, la grotte de l'Eremita, appelée également Tana dell'Armittu, fait l'objet d'une intervention archéologique menée par l'Université de Genève (direction M. Besse). Suite à des sondages effectués en 2012 lors desquels furent mises au jour, entre autres, des perles spiralées et une épingle en bronze, une fouille programmée a été organisée dès 2013. Notre contribution présente les données de terrains de l'année 2013. La fouille archéologique s'est déroulée avec les étudiants en archéologie, l'aspect didactique - auquel nous sommes fermement attachés - étant un des objectifs de cette fouille.

A Simulation-based Performance Evaluation of Heuristics for Dew Computing

A Task Execution Scheme for Dew Computing with State-of-the-Art Smartphones

2021

The computing resources of today’s smartphones are underutilized most of the time. Using these resources could be highly beneficial in edge computing and fog computing contexts, for example, to support urban services for citizens. However, new challenges, especially regarding job scheduling, arise. Smartphones may form ad hoc networks, but individual devices highly differ in computational capabilities and (tolerable) energy usage. We take into account these particularities to validate a task execution scheme that relies on the computing power that clusters of mobile devices could provide. In this paper, we expand the study of several practical heuristics for job scheduling including executi…

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…

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…

The Co-creation Canvas

2021

Abstract Digital transformation has become an increasingly important topic among enterprises and in research. The adoption of enterprise systems is such an investment, and it usually requires significant change management activities to realize the potential benefits. One important issue is how firms should go about to make investments in appropriate digital technology – and the appropriate changes to organizational processes and business models. This is particularly challenging for small and medium-sized enterprises (SMEs). They generally have very limited resources, and they usually depend on external input and cooperation with other companies. Therefore, a successful strategy for many SME…

The Use of Experts Panels in ERP Cost Estimation Research

2011

Published version of a chapter in the book: Enterprise information systems. The original publication is available at www.springerlink.com, http://dx.doi.org/10.1007/978-3-642-16419-4_10 This paper is an effort towards illustrating the use of expert panel (EP) as a mean of eliciting knowledge from a group of enterprise resource planning (ERP) experts as an exploratory research. The development of a cost estimation model (CEM) for ERP adoptions is very crucial for research and practice, and that was the main reason behind the willingness of experts to participate in this research. The use of EP was very beneficial as it involved various data collection and visualisation techniques, as well as…

Tension in the data environment: How organisations can meet the challenge

2022

Big Data is becoming ubiquitous - widely applied across organisations, industry sectors and society. However, the opportunities and risks it presents are not yet fully understood. In this paper we identify and explore the tensions that Big Data can create at multiple levels, focusing on the need for organisations to meet the challenges that can arise. We draw on insights from twelve papers published in the Special Issue of Technological Forecasting & Social Change entitled “Tension in the Data Environment: Can Organisations Meet the Challenge?” in order to build a ‘Multi-Layer Tensions Model’ that highlights key pressures and challenges in the BD environment. We find evidence of tensions of…

Co-creation in networks of SMEs: a conceptual model of the co-creation process

2021

Abstract The ability to adopt new digital technology is a very challenging endeavour, especially for small and medium-sized enterprises (SMEs), who because of resource poverty are dependent on external input and cooperation with other companies. Recent research has indicated that co-creation among SMEs is a promising way to overcome such limitations. However, there has been very limited research on the co-creation process, and we have little understanding about how SMEs would go about to establish and run a co-creation network. We propose a conceptual model based on our review of the literature and our empirical findings from investigating co-creation in four networks. The results expand ou…
