AS4 message exchange protocol consolidation through the European CEF eDelivery infrastructure
2020
Since 2014, the European Union has supported the creation of cross-border communication networks based on an AS4 eDelivery solution through the Connecting Europe Facility. This article describes the current status of the uptake of the AS4 message exchange protocol in accordance with both the European infrastructure CEF eDelivery and the European regulation n°910/2014 on electronic identification and trust services for electronic transactions in the internal market. The main objective is to present an analysis of the achieved results from the implementation of the AS4 solution in several European projects carried out during the last 12 years to verify the impact of these projects around Euro…
A Stochastic Routing Algorithm for Distributed IoT with Unreliable Wireless Links
2016
Punctual and reliable transmission of collected information is indispensable for many Internet of Things (IoT) applications. Such applications rely on IoT devices operating over wireless communication links which are intrinsically unreliable. Consequently to improve packet delivery success while reducing delivery delay is a challenging task for data transmission in the IoT. In this paper, we propose an improved distributed stochastic routing algorithm to increase packet delivery ratio and decrease delivery delay in IoT with unreliable communication links. We adopt the concept of absorbing Markov chain to model the network and evaluate the expected delivery ratio and expected delivery delay …
Peer-to-Peer-Technologien — Einflüsse digitaler dezentraler Ressourcennutzung auf elektronische Märkte
2003
Peer-to-Peer-Systeme sind in jungerer Zeit hauptsachlich durch die verbreiteten und oft kritisierten Musiktauschborsen wie Napster1 oder Gnutella2 bekannt geworden. Oftmals wird „Peer-to-Peer“sogar mit dem Austausch von Musik- und Videodateien gleichgesetzt. Diese Reduzierung des Begriffs auf das blose Austauschen von Dateien (Filesharing) wird jedoch nicht dem Peer-to-Peer-Begriff und erst recht nicht dem Potenzial des Peer-to-Peer Computing gerecht. Filesharing darf insofern nur als eine spezielle Applikation gesehen werden, die sich mit Hilfe von Peer-to-Peer-Technologien bewaltigen lasst.
Four steps to identify mechanisms of ICT4D: A critical realism-based methodology

Controversias en la transición del libro de texto en papel y electrónico a los contenidos digitales
2018
It is suggested that, given the economic and cultural scale that the book represents in our society, the layout of the paper and digital version will live together for a long time. Therefore, textbooks will suffer a very similar fate. The current change is focused on the transformation of textbooks in digital content with different formats and access routes. Through this process, we are studying the disputes that these changes cause, whereas they reflex the level of assimilation of the technological innovations on the part of citizens. By means of ethnographic strategies, we try to understand inductively how different educational agents are accepting such innovations. The centres that we ha…
Catalogue of Interactive Learning Objectives to improve an Integrated Medical and Dental Curriculum.
2016
ABSTRACT Introduction Online learning media are increasingly being incorporated into medical and dental education. However, the coordination between obligatory and facultative teaching domains still remains unsatisfying. The Catalogue of Interactive Learning Objectives of the University Clinic of Mainz (ILKUM), aims to offer knowledge transfer for students while being mindful of their individual qualifications. Its hierarchical structure is designed according to the Association for Dental Education in Europe (ADEE) levels of competence. Materials and methods The ILKUM was designed to establish a stronger interconnection between already existing and prospective learning strategies. All conte…
Le « Semestre Rebond » après la réorientation obligatoire en première année commune des études de santé (PACES) en France
2018
Contexte et problématique :L’échec en premier cycle universitaire s’est constitué en question politique et scientifique, avec une situation encore plus marquée pour les études de santé. Pourtant, peu de recherches encore sont consacrées à ces situations et aux dispositifs d’aide proposés.Objectifs :Cette recherche vise à caractériser les profils des étudiants en situation d’échec, leurs stratégies de réorientation au nombre desquelles l’accès à un dispositif d’accompagnement proposé à l’université de Bourgogne, le semestre Rebond. Elle met en évidence les apports de ce dispositif perçus par les étudiants et ses effets sur les parcours de formation ultérieurs.Méthodes :L’étude mobilise les d…
Empowering education professionals with twenty-first century skills through master's of education dissertation/thesis work
2021
This paper aims to explore the potential role of Master’s of Education dissertation/thesis work in developing twenty-first century skills. A total of 600 education professionals studying Master’s of Education programmes in five countries – Poland, Portugal, England, Latvia, and Romania – were surveyed. The findings have revealed that participants recognise the usefulness of twenty-first century skills for their (future) professional practice, and perceive dissertation/thesis work as a valuable foundation for developing these skills. This study offers practical implications for designers of Master’s of Education programmes and contributes to our understanding that this assignment is not only…
Human Coaching Methodologies for Automatic Electronic Coaching (eCoaching) as Behavioral Interventions With Information and Communication Technology:…
2021
Background We systematically reviewed the literature on human coaching to identify different coaching processes as behavioral interventions and methods within those processes. We then reviewed how those identified coaching processes and the used methods can be utilized to improve an electronic coaching (eCoaching) process for the promotion of a healthy lifestyle with the support of information and communication technology (ICT). Objective This study aimed to identify coaching and eCoaching processes as behavioral interventions and the methods behind these processes. Here, we mainly looked at processes (and corresponding models that describe coaching as certain processes) and the methods th…
Smartphone Apps for the Treatment of Mental Disorders: Systematic Review
2020
Background Smartphone apps are an increasingly popular means for delivering psychological interventions to patients suffering from a mental disorder. In line with this popularity, there is a need to analyze and summarize the state of the art, both from a psychological and technical perspective. Objective This study aimed to systematically review the literature on the use of smartphones for psychological interventions. Our systematic review has the following objectives: (1) analyze the coverage of mental disorders in research articles per year; (2) study the types of assessment in research articles per mental disorder per year; (3) map the use of advanced technical features, such as sensors…
