A new paradox of the digital economy - Structural sources of the limitation of GDP statistics
2018
The Internet has dramatically changed the way we conduct business and our daily lives by provided us with unprecedented services and conveniences. However, contrary to such accomplishments, productivity in industrialized countries is now experiences an apparent decline. This has raised the question of a possible productivity paradox in the digital economy. The limitation of GDP statistics in measuring the advancement of the digital economy has thus become an important subject. This paper analyzed the structural sources of this problem. Utilizing the results of empirical analyses of national, industrial, and individual behavior in the digital economy, solutions to these critical issues were …
Business continuity of business models : Evaluating the resilience of business models for contingencies
2019
Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to f…
Co-Creation of Value for IT-Enabled Services : A Case of Geocaching
2013
This study explores how value is co-created in one particular IT-enabled service, geocaching. Consumer Information Systems (CIS) framework is used as a sensitizing framework to study experienced geocachers' (n=14) perceptions of what they value in geocaching. The following core values emerged that motivate people to co-create value in geocaching: challenging oneself and others, joy of success, learning, and social relations. The results reveal that geocaching is distinctively hedonic in nature, as people pursue happiness and utility via geocaching. Even support for the geocaching community was motivated by such values. In addition, the results reveal that the environment of geocaching and s…
Explaining Extreme Mobile Experiences
2013
Extreme service or product experiences have a major influence on perceptions and behavior. Therefore, numerous studies have collected such single positive and negative experiences to understand which factors affect (dis)satisfaction, value, and quality. However, most of these studies lack the process approach needed for understanding why and how these experiences take place and proceed, whereas the context of mobile applications has also remained highly unexplored. This study aims to fill the gap by presenting the mobile experience process model with empirical evidence of extreme experiences from 606 actual mobile application users. With the help of the model and the detailed descriptions o…
Adaptive Vocabulary Learning Environment for Late Talkers
2016
The main aim of this research is to provide children who have an early language delay with an adaptive way to train their vocabulary taking into account individuality of the learner. The suggested system is a mobile game-based learning environment which provides simple tasks where the learner chooses a picture that corresponds to a played back sound from multiple pictures presented on the screen. Our basic assumption is that the more similar the concepts (in our case, words) are, the harder the recognition task is. The system chooses the pictures to be presented on the screen by calculating the distances between the concepts in different dimensions. The distances are considered to consist o…
Agent assisted interactive algorithm for computationally demanding multiobjective optimization problems
2015
Abstract We generalize the applicability of interactive methods for solving computationally demanding, that is, time-consuming, multiobjective optimization problems. For this purpose we propose a new agent assisted interactive algorithm. It employs a computationally inexpensive surrogate problem and four different agents that intelligently update the surrogate based on the preferences specified by a decision maker. In this way, we decrease the waiting times imposed on the decision maker during the interactive solution process and at the same time decrease the amount of preference information expected from the decision maker. The agent assisted algorithm is not specific to any interactive me…
Parallel and Distributed Resource Allocation With Minimum Traffic Disruption for Network Virtualization
2017
Wireless network virtualization has been advocated as one of the most promising technologies to provide multifarious services and applications for the future Internet by enabling multiple isolated virtual wireless networks to coexist and share the same physical wireless resources. Based on the multiple concurrent virtual wireless networks running on the shared physical substrate, service providers can independently manage and deploy different end-users services. This paper proposes a new formulation for bandwidth allocation and routing problem for multiple virtual wireless networks that operate on top of a single substrate network to minimize the operation cost of the substrate network. We …
Three-dimensional splitting dynamics of giant vortices in Bose-Einstein condensates
2018
We study the splitting dynamics of giant vortices in dilute Bose-Einstein condensates by numerically integrating the three-dimensional Gross-Pitaevskii equation in time. By taking advantage of tetrahedral tiling in the spatial discretization, we decrease the error and increase the reliability of the numerical method. An extensive survey of vortex splitting symmetries is presented for different aspect ratios of the harmonic trapping potential. The symmetries of the splitting patterns observed in the simulated dynamics are found to be in good agreement with predictions obtained by solving the dominant dynamical instabilities from the corresponding Bogoliubov equations. Furthermore, we observe…
Consequences of Discontinuing Knowledge Work Automation – Surfacing of Deskilling Effects and Methods of Recovery
2018
IS automation pervades business processes today. Thus, concerns have been raised about automation’s potential deskilling effects on knowledge workers. We conduct a revelatory case study about an IT service firm where a managerial decision was taken to discontinue a fixed assets management (FAM) software that provided seemingly effective automation of fixed assets accounting and reporting. We study how automation can result in latent deskilling that later becomes apparent when the system gets discontinued, causing disruptions in employees’ daily work and organizational processes. We also investigate how the employees and the company recover from this disruption by leveraging various coping s…
Technostress and social networking services: Explaining users' concentration, sleep, identity, and social relation problems
2018
It is common for users of social networking sites and services (SNS) to suffer from technostress and the various associated strains that hinder their well‐being. Despite prior SNS stress studies having provided valuable knowledge regarding SNS stressors and their use consequences, they have not examined the various strains related to well‐being that those stressors can create nor the underlying SNS characteristics. To address this gap in the research, we used a qualitative approach involving narrative interviews. As a contribution, our findings reveal four types of strains related to well‐being (concentration problems, sleep problems, identity problems, and social relation problems) as well…
