QoS Mechanisms for IEEE 802.11 Wireless LANs
2004
Currently the Internet provides users with access to information across the world using IP technology. Until now most access points to the Internet have been fixed stations at given locations, but with increasing sales of mobile devices, mobility has become a major trend. Therefore, the Internet is becoming more and more heterogeneous due to the recent explosion of wireless networks. The IEEE 802.11 wireless LAN (WLAN) is the most widely used WLAN standard nowadays. Currently the IEEE 802.11 standard specifies an over-the-air interface between wireless devices. However, QoS services over this technology are still being defined aiming to provide support to multiple applications. Thus, a larg…
SUP&R DST: SUstainable pavement & railways decision support tool
2018
6th International Symposium on Life-Cycle Civil Engineering, IALCCE 2018; Ghent; Belgium; 28 October 2018 through 31 October 2018, GHENT, BELGIQUE, 28-/10/2018 - 31/10/2018; In order to help the decisions makers to efficiently address eco-design for transport infrastructure technologies, a decision support toll (DST) was developed in the scope of the training-through-research programme Sustainable Pavements & Railways Initial Training Network (www.superitn.eu). It consists of a computational platform that implements a conceptual framework developed to quantify sustainability. It comes with a set of sustainability indicators tailored to both road and railway systems as well as several ob…
Navigating in the Digital Jungle : Articulating Combinatory Affordances of Digital Infrastructures for Collaboration
2019
During digital transformation, companies integrate digital technologies creating large and complex digital infrastructures. These digital infrastructures hold combinatory affordances enabling companies to achieve outcomes that are more than the sum of their parts (i.e., the individual digital technologies). Owing to the complexity of digital infrastructures, these combinatory affordances are ever-present but hidden in the thicket of the infrastructure making their effective use a challenge. We report on an ethnographic study of a large German car manufacturer (Car Inc.) that increasingly integrated digital technologies into its infrastructure as part of its digital transformation strategy. …
The impact of globalization on regional development and competitiveness: cases of selected regions
2019
International audience; The objective of this study is to conduct an analysis of regional development and competitiveness in the EU and Latvia under current conditions of economic globalization. This paper makes an attempt to evaluate a theory of regional development and regional competitiveness concept in relation to regional competitiveness in the light of current global economic changes. The authors emphasise that the regional development is based on competitive advantages, which has been a subject of fundamental research by Michal Porter and that serves as a basis for the current scientific methodology to assess competitiveness of regions and countries. The authors support a view of man…
"Tea for two": the Archive of the Italian Latinity of the Middle Ages meets the CLARIN infrastructure
2020
This paper aims at showing how integrating the Archive of the Italian Latinity of the Middle Ages (ALIM) into the ILC4CLARIN repository can provide mutual benefits. Making ALIM available to a large community of scholars and researchers, on the one side, represents the first step to reduce the lack of resources for Medieval Latin in CLARIN and, on the other side, constitutes an unprecedented contribution to not only linguistic investigations, but also to the studies of the culture and science at the basis of the Western European society. The paper describes the adopted approach aiming to keep intact the structure of the archive and its metadata, which are both accurately mirrored into the IL…
Moving enterprise resource planning (ERP) systems to the cloud: the challenge of infrastructural embeddedness
2021
Cloud enterprise resource planning (ERP) solutions allow organizations to support and coordinate key business processes by leveraging virtualization. Nevertheless, moving ERPs to the cloud is not straightforward, and organizational cloud ERP initiatives raise multiple concerns. We conducted an in-depth systematic review of relevant research literature and identified six key concerns related to cloud ERP implementation: a) the introduction of new ERP work arrangements, b) the migration of legacy data, c) the assurance of compliance with extant rules and regulations for security, d) the continuous alignment between ERP functionality and business processes, e) the ongoing integration between E…
Exploring the Relationship between Information Technology Infrastructure Library and Process Management: Theory Development and Empirical Testing
2014
This paper investigates whether information technology (IT) departments that implement the IT Infrastructure Library (ITIL) processes also employ process management. This is a pertinent issue, as ITIL not only implies a time-limited program for redesigning vital IT processes according to best practices but a complete transformation to ITIL also implies that processes are managed on a daily basis. Without process management, ITIL will not be a success beyond its initial implementation. A survey of 444 Nordic ITIL experts was conducted to examine if there is a correlation between the implementation of ITIL processes and process management. The results are unambiguous and promising for sustain…
The impact of senior management involvement, organisational commitment and group efficacy on ITIL implementation benefits
2014
Published version of an article from the journal: Information Systems and e-Business Management. Also available from Springerlink: http://dx.doi.org/10.1007/s10257-014-0253-4 Senior management involvement, organisational commitment and group efficacy are expected to have a positive impact on Information Technology Infrastructure Library (ITIL) implementation benefits. Specifically, more involvement, commitment and efficacy should produce greater achievement. Analysing data from a survey of 446 Nordic ITIL experts, this paper examines the relationships between these predictor factors and benefits, and investigates which is most critical. This study verifies the importance of all factors, but…
Comparing Cybersecurity Information Exchange Models and Standards for the Common Secure Information Management Framework
2021
Cyber threats have increased in spite of formal economic integration in the world. Decision-makers and authorities need to respond to the growing challenge of cyberthreats by increasing cooperation. Information is one of the main facilities when the objective is to prevent hybrid threats at the EU level and between the western countries. The main purpose of the study is to find out separating and combining factors concerning existing cyber information sharing models and information management frameworks in western countries. The aim is also to find out crucial factors, which affect the utilization of a common Early Warning System for the ECHO stakeholders. The main findings are that unclear…
Understanding the ITIL Implementation Project: Conceptualization and Measurements
2011
The purpose of this research is to contribute to the theorizing of ITIL. The paper provides a model that conceptualizes the scope and content of an ITIL implementation project, and it tests and validates measurements based on a literature study and data from a survey of 446 Nordic ITIL experts.
