PMG-Pro: A Model-Driven Development Method of Service-Based Applications
2011
Published version of a chapter published in the book: SDL 2011: Integrating System and Software Modeling. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-25264-8_12 In the Internet of Things, billions of networked and software-driven devices will be connected to the Internet. They can communicate and cooperate with each other to form a composite system. In this paper, we propose PMG-pro (present, model, generate and provide), a language independent, bottom-up and model-driven method for the development of such composite system. We envision that all devices in the Internet of Things provide their functionalities as services. From a service description, a service pre…
Consumer Information Systems as Services
2017
Consumer Information Systems (CIS) are a type of information systems that provides services to consumers instead of addressing users in traditional organizational settings, such as Internet based television. Services typically involve a trade-off between achieving high service productivity and quality. The use of service mass customization to successfully address these issues of both productivity and quality in a service context is proposed. We suggest that the development of Consumer Information Systems as Services (CISaS) may achieve such service mass customization. This paper presents a conceptual framework and investigates how it applies to a set of Internet Protocol Television (IPTV) o…
Media Delivery to Remote Renderers Controlled by the Mobile Phone
2009
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.
Unit-level fairness and quality within the health care industry: A justice–quality model
2014
We test a justice–quality model in which peer justice and justice climate are related to the service quality provided by the work unit. Based on the effort–reward imbalance model, we propose that units perceiving fair treatment provide better delivery of the core service (functional service quality) and better relational service beyond the core service (relational service quality). We also test whether the cross-level relationship of high service quality delivered by work units translates into high customer ratings of the service quality they receive. Furthermore, we propose that high service quality increases the work unit’s influence on their customers’ quality of life (QoL). We test thes…
How does information technology– based service degradation influence consumers’ use of services? An information technology–based service degradation …
2019
Information technology is crucial for modern services. Service delivery may include a complex mix of information technology and telecommunication providers, global networks and customers’ information technology devices. This research focuses on service failures that are caused by information technology problems, which we conceptualize as information technology-based service degradation (ITSD). When information technology-based service degradation occurs in a modern service, the information technology problem may originate from the service provider, another partner or any information technology equipment involved. But the customer may not be able to pinpoint the source of the problem immedi…
Logistics service quality: a new way to loyalty
2008
PurposeNow‐a‐days, logistics research focuses on the ability of logistics to deliver a quality service and generate greater satisfaction with the delivered service. Therefore, the aim of this work is to analyze the quality, satisfaction, and loyalty sequence in the logistic service delivery context, with the purpose of considering the role of information and communication technologies (ICT) in this chain of effects.Design/methodology/approachAfter reviewing the different approaches given by the literature, SEM analysis is used to contrast the hypotheses for the analyzed constructs in the presence of high/low ICT level. A questionnaire based on personal survey was conducted among manufacture…
Case study for 3G/UMTS services and billing methods
2001
The 3G/UMTS-networks and services will provide a wide range of telecommunication services. To achieve, this, we need a new view to networks, network services and service abilities. The amount of service providers in the 3G networks will be at least the same than in the present Internet. The amount of users in the 3G networks will overgrow the user amount of Internet forming a global worldwide communication society. This paper discusses customer billing in the 3G world. There are some main issues that are not very, clear to all 3G service and network providers, which however, should be settled before, 3G networks are operational. One of the most important matters is the QoS (Quality of Servi…
Switching Behaviour in Smart Phone Messaging Services : It’s a Question of Context, Content, and Features of the Service
2021
This paper studies switching behaviour in smart phone messaging services. This study aims to add knowledge about the factors affecting switching behaviour in smart phone messaging services. The empirical study is qualitative, and the data was collected with interviews using the laddering method. This study was carried out to find out the reasons behind customer decisions when choosing between smart phone messaging services. Using the Push-Pull Mooring framework, the findings of this study indicate that the switching decision regarding smart phone messaging service is influenced by three factors: the context of the message, the content of the message, and the features of the service.
A global service level guarantee in NGN networks
2010
In this paper, we propose an end-to-end service level negotiation protocol which enables a global service offer covering quality of service (QoS) and security while taking into account user's mobility in this offer. This protocol provides all the domains involved in the transport of a various offered services with a negotiation capability to achieve an agreement on a service level. This paper shows also results of measurements evaluating the performances of the considered negotiation protocol and security impact on QoS.
Healthcare access of immigrants: An integrated ecological framework
2019
Access to healthcare impacts in health, and for its importance it has been conceptualized by different theoretical models. Theories tackling social barriers have been established too. Nevertheless, a lack of theorization about healthcare access of immigrants exists, and there is no theory able to integrate all the scientific literature on this and its impact on the health of immigrants. In order to study the factors relating to the access of immigrants and to guide the development and evaluation of public health interventions, an integrative approach is needed. In this regard, from an ecological perspective healthcare access of immigrants would be shaped by interrelated factors in different…
