Explaining non-adoption of electronic government services by citizens. A study among non-users of public e-services in Latvia
2018
This paper analyses citizen motives for not using electronic government services. Using qualitative interviews among users of Citizens´ Service Centers in Latvia, this paper analyses the motives of citizens not to use electronic government services but to rely on non-electronic equivalents or on in-person assistance. It expands the literature on e-commerce and e-government through an explicit focus on non-adoption rather than adoption. Findings show a higher than expected importance of hardware and internet availability, as well convenience factors as important reasons for non-adoption. The research furthermore reveals that the well-intentioned supply of non-electronic alternatives may hamp…
Systemic Development of Service Innovation
2015
This chapter explores the intrinsic characteristics of services and service systems and presents systemic approach to produce service innovations. The chapter consists of elaborating the characteristics of services and the principles of systemic development, discussing service matrixes, service systems, service strategies and business models, and special challenges related to the development of services and service innovations. Services are always produced in service systems consisting of combination of service personnel and information systems. Customers are involved in these systems by interacting with the front end of service organization. The key issue in service development and innovat…
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.
Improving Usability of Location-Based Services with User-Centric Data Querying
2004
In this paper, we describe a computational model that produces a dataset which we consider to be an appropriate response for “give me a description of my neighborhood” type of queries in location-based services Our attempt is to reflect the abstraction ability of a specific user, and in this way to maximize the usability of the service under restrictions on data volume posed by technical, economical and cognitive factors of mobile environments We also present the results of instantiating the model for a simple LBS.
GPCALMA: A Grid-based tool for mammographic screening
2005
The next generation of High Energy Physics (HEP) experiments requires a GRID approach to a distributed computing system and the associated data management: the key concept is the Virtual Organisation (VO), a group of distributed users with a common goal and the will to share their resources. A similar approach is being applied to a group of Hospitals which joined the GPCALMA project (Grid Platform for Computer Assisted Library for MAmmography), which will allow common screening programs for early diagnosis of breast and, in the future, lung cancer. HEP techniques come into play in writing the application code, which makes use of neural networks for the image analysis and proved to be useful…
Joint Radio and Computational Resource Allocation in IoT Fog Computing
2018
The current cloud-based Internet-of-Things (IoT) model has revealed great potential in offering storage and computing services to the IoT users. Fog computing, as an emerging paradigm to complement the cloud computing platform, has been proposed to extend the IoT role to the edge of the network. With fog computing, service providers can exchange the control signals with the users for specific task requirements, and offload users’ delay-sensitive tasks directly to the widely distributed fog nodes at the network edge, and thus improving user experience. So far, most existing works have focused on either the radio or computational resource allocation in the fog computing. In this work, we inve…
GUI Usability in Medical Imaging
2009
The diffusion of computer technologies in everyday life has involved the birth of standard methodologies to control their development. Indeed, the purpose of standardization procedures consists of providing rules aimed to control technologies leaving no space for empirical improvisations. In general, medical software manufacturers provide their applications with Graphic User Interfaces (GUI) that are not compliant with any clear and standard usability criterion. The only guideline is the creation of GUIs inherited from the ones adopted on medical consoles because physicians use them routinely. This paper addresses this issue: medical software interfaces should be designed trying to overcome…
User-Centered Design of a National Medical Registry for Tick-Borne Diseases
2018
Tick-borne diseases are increasing in a global perspective, with Lyme disease and tick-borne encephalitis as the most frequent. The Norwegian National Advisory Unit on Tick-borne Diseases is preparing the development of a national medical registry for clinical follow-up of patients with tick-borne diseases based on the best practice guidelines and for research purposes. This paper presents the methodological approach of a user-centered design process applied in the initial phase of the registry development. A user workshop identified user needs, requirements and proposed a service workflow for the registry operation. As the next step, a simulation of the proposed service workflow was perfor…
Exploring End-User Reactions to Variations in the Value Proposition of Value Services
2009
Value services are most often innovations where endusers have little or no experience from using the service. Designing business models for such services is a challenging task including the design of value propositions that are perceived and interpreted through end-users’ complex value assessments. This study presents the results from a study of end-user value assessments of value proposition variations for two value services – mobile VoIP and multi play services. The study suggests a method for investigating end-user reactions to value proposition variations and presents the effects of these variations on attribute perceptions and value drivers. The main contribution of the study is method…
Review of High Resolution Thermal Infrared Applications and Requirements: The Fuegosat Synthesis Study
2013
High resolution thermal infrared remote sensing can have a wide range of applications. In this chapter we describe the different applications and requirements identified after a revision study in the framework of the Fuegosat Synthesis Study (FSS). This project was funded by the European Space Agency (ESA), and the three main objectives were: (i) review of applications and analyses for user requirements, (ii) consolidation of user requirements over a broad range of applications, and (iii) matching of user requirements and industry concepts to identify and outline a set of potential mission scenarios and their corresponding requirements. This chapter focuses on issues (i) and (ii). These obj…
