Intangible Resource Management - an Organisational Approach
2017
Abstract This article is seeking to improve the intangible resource management at organisation level by highlighting the importance of this type of management on one hand and, on the other hand, by creating a pattern describing the process to be followed by the organisations that wish to implement an intangible resource management system. Thus, this study shows the premises underlying the author’s approaches on the importance of intangible resource management, the concept of intangible resource management is substantiated, and some general principles are formulated regarding the substantiation and implementation of this type of management. Specific processes representing the scope of the ma…
The implementation of mindfulness in healthcare Systems: a theoretical analysis
2014
Abstract Objective Evidence regarding the efficacy of mindfulness-based interventions (MBIs) is increasing exponentially; however, there are still challenges to their integration in healthcare systems. Our goal is to provide a conceptual framework that addresses these challenges in order to bring about scholarly dialog and support health managers and practitioners with the implementation of MBIs in healthcare. Method This is an opinative narrative review based on theoretical and empirical data that address key issues in the implementation of mindfulness in healthcare systems, such as the training of professionals, funding and costs of interventions, cost effectiveness and innovative deliver…
Assessing first-year engineering students' pre-university mathematics knowledge: preliminary validity results based on an item response theory model
2020
The importance of students’ prior knowledge to their current learning outcomes cannot be overemphasised. Students with adequate prior knowledge are better prepared for the current learning materials than those without the knowledge. However, assessment of engineering students' prior mathematics knowledge has been beset with a lack of uniformity in measuring instruments and inadequate validity studies. This study attempts to provide evidence of validity and reliability of a Norwegian national test of prior mathematics knowledge using an explanatory sequential mixed-methods approach. This approach involves use of an item response theory model followed by cognitive interviews of some students …
Performance Analysis of Memory Cloning Solutions in Mobile Edge Computing
2018
This paper deals with the problem of service migration in the emerging scenarios of Mobile Edge Computing. Mobile edge computing is achieved by moving the traditional cloud infrastructures, exploited by many today applications, close to the network edge in order to reduce the response times in the so called tactile-internet. However, because of user mobility, such an application architecture may pose the problem of service migration in case of handover from one server site to another. After introducing the current solutions for dealing with service migration and, in particular, the approaches based on service decomposition into multiple layers, we quantify the migration time and the service…
NFVMon: Enabling Multioperator Flow Monitoring in 5G Mobile Edge Computing
2018
With the advances of new-generation wireless and mobile communication systems such as the fifth-generation (5G) mobile networks and Internet of Things (IoT) networks, demanding applications such as Ultra-High-Definition video applications is becoming ever popular. These applications require real-time monitoring and processing to meet the mission-critical quality of service requirements and are expected to be supported by the emerging fog or edge computing paradigms. This paper presents NFVMon, a novel monitoring architecture to enable flow monitoring capabilities of network traffic in a 5G multioperator mobile edge computing environment. The proposed NFVMon is integrated with the management…
Low-Latency Infrastructure-Based Cellular V2V Communications for Multi-Operator Environments With Regional Split
2021
Mobile network operators are interested in providing Vehicle-to-Vehicle (V2V) communication services using their cellular infrastructure. Regional split of operators is one possible approach to support multi-operator infrastructure-based cellular V2V communication. In this approach, a geographical area is divided into non-overlapping regions, each one served by a unique operator. Its main drawback is the communication interruption motivated by the inter-operator handover in border areas, which prevents the fulfillment of the maximum end-to-end (E2E) latency requirements of fifth generation (5G) V2V services related to autonomous driving. In this work, we enable a fast inter-operator handove…
LEARNING TOGETHER EVERYWHERE ANYTIME. MOBILE LEARNING IN HIGHER EDUCATION
2015
Today, the use of mobile learning in higher education can be widespread only if teachers and students are able to understand their possibilities and applications in the right way. The present research aims to analyse types of possessed mobile devices, competences in their use and successful applications in higher education courses. A specific questionnaire has been created and divided into four areas: 1) general personal information, 2) possessed and frequently used mobile devices, 3) awareness of the mobile device potential in distance learning, 4) their advantages in free and informal learning environments). The questionnaire, previously validated, was submitted on-line to a large group o…
Neural Multimodal Belief Tracker with Adaptive Attention for Dialogue Systems
2019
Multimodal dialogue systems are attracting increasing attention with a more natural and informative way for human-computer interaction. As one of its core components, the belief tracker estimates the user's goal at each step of the dialogue and provides a direct way to validate the ability of dialogue understanding. However, existing studies on belief trackers are largely limited to textual modality, which cannot be easily extended to capture the rich semantics in multimodal systems such as those with product images. For example, in fashion domain, the visual appearance of clothes play a crucial role in understanding the user's intention. In this case, the existing belief trackers may fail …
Formal Modeling and Discrete-Time Analysis of BPEL Web Services
2008
International audience; Web services are increasingly used for building enterprise information systems according to the Service Oriented Architecture (SOA) paradigm. We propose in this paper a tool-equipped methodology allowing the formal modeling and analysis of Web services described in the BPEL language. The discrete-time transition systems modeling the behavior of BPEL descriptions are obtained by an exhaustive simulation based on a formalization of BPEL semantics using the Algebra of Timed Processes (ATP). These models are then analyzed by model checking value-based temporal logic properties using the CADP toolbox. The approach is illustrated with the design of a Web service for GPS na…
Organizational Ethics, Position and Their Relationship to Gender, Before and During Pandemic
2021
This research investigates the levels of organizational ethics (OETH) among knowledge workers (KW), using their work information and communication technologies (ICT) with their executive position (supervisor/subordinate), in regional enterprises in Poland before and during the COVID19 pandemic. We analyzed levels of OETH and its three dimensions as organizational optimism (ETO), corporate social responsibility (CSR), top management action (TMA). We conducted our study twice, using an online survey among 137 KW before and 127 KW during a pandemic, combining random and snowball sampling to select data. We used multivariate statistical methods such as analysis of variance and causal moderation…
