The value of a network in the digital era: insights about Doctor Chat case study
2017
Networks are ubiquitous in our lives in their social, physical, and digital forms. A growing number of firms today rely entirely on networking and lack a physical location or material infrastructure; they are, so to speak, 'liquid'. Through a theoretical analysis and its application to the case of Doctor Chat mobile app, this paper aims to analyse the fundamental laws of networks and to answer the following questions: 1) are the traditional methods to estimate the network value still valid in the current digital age and in particular for mobile applications?; 2) how do the laws of networks work when networks expand? We conclude with some suggestions for a research agenda in order to inspire…
The Role of Big Data in Addressing Societal Challenges: A Systematic Mapping Study
2019
Part 2: Big Data Analytics; International audience; Big data has recently become the focus of academic and corporate investigation due to its high potential in generating business and social value. We have done a systematic mapping of the literature related to big data and its applications leading to social change through the lens of social innovation. The search strategy initially resulted in 593 papers, and after applying inclusion exclusion criteria a total of 156 papers were mapped; 59% of which were identified as empirical studies. This mapping investigated the publication frequency of the studies, research approach and contributions, research areas and article distribution per journal…
Analysis of Viral Advertisement Re-Posting Activity in Social Media
2016
More and more businesses use social media to advertise their services. Such businesses typically maintain online social network accounts and regularly update their pages with advertisement messages describing new products and promotions. One recent trend in such businesses’ activity is to offer incentives to individual users for re-posting the advertisement messages to their own profiles, thus making it visible to more and more users. A common type of an incentive puts all the re-posting users into a random draw for a valuable gift. Understanding the dynamics of user engagement into the re-posting activity can shed light on social influence mechanisms and help determine the optimal incentiv…
Click and drive: Consumer attitude to product development: Towards future transformations of the driving experience
2016
Purpose – The purpose of this paper is to supply indications that may be useful in the process of development of new products that fully exploit the value potential of Internet of Things (IoT) technologies in the automotive industry. To this aim, the authors investigate how applications of the IoT to smart vehicles are perceived by consumers and describe different ways to increase their satisfaction. Design/methodology/approach – After a literature review focused on IoT and consumer behaviour in the automotive industry, the authors apply the Kano model to find the drivers for achieving customer satisfaction with new product developments in smartcars. Findings – Automotive companies need to…
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 …
Online Communication with Citizens. Should Latvian Public Institutions Learn from Foreign Experience?
2021
Civic engagement is a core value of democracy that approves legitimacy of democracy itself and decisions made by public institutions. In Latvia, civic engagement rates are decreasing, thus for public institutions it is important to find new ways how to engage citizens in the decision-making process. In the twenty-first century, it means that public institutions should also be present in social media. The objectives of the article are to identify foreign experience how public institutions are using social media for civic engagement and evaluate the reasons for Latvian public institutions to learn from this foreign experience. Accordingly, methods of the research are analysis of scientific pu…
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…
Online value creation in small service businesses: the importance of experience valence and personal values
2012
Perceived value is of great interest in current marketing research. However, in the area of Internet as a shopping channel of small businesses, there has been little analysis of customer perceived value and its determinants. This paper examines two little analysed aspects of value creation, experience valence and personal values. The analysis of data from a survey of tourism service purchase shows that experience valence, in terms of relevant information, ease of use and customer service, clearly influences perceived value after the online shopping experience. In contrast, only personal values of sense of security and sense of accomplishment influence perceived value.
Privacy-preserving scheme for mobile ad hoc networks
2011
This paper proposes a decentralized trust establishment protocol for mobile ad hoc networks (MANETs), where nodes establish security associations. In order to achieve privacy and security, we use homomorphic encryption and polynomial intersection so as to find the intersection of two sets. The first set represents a list of recommenders of the initiator and the second set is a list of trusted recommenders of the responder. The intersection of the sets represents a list of nodes that recommend the first node and their recommendations are trusted by the second node. In our experimental results we show that our scheme is effective even if there are 30 trusted nodes.
A Non-WSSUS Mobile-to-Mobile Channel Model Assuming Velocity Variations of the Mobile Stations
2017
This paper aims to characterize the effects that the velocity variations of the mobile stations (MSs) produce on the correlation properties of non-stationary time-frequency (TF) dispersive mobile- to-mobile (M2M) fading channels. Toward that end, we propose a novel geometrical model for non-wide-sense stationary uncorrelated scattering (non-WSSUS) M2M channels that incorporates such variations following a plane wave propagation approach. Capitalizing on the mathematical simplicity of this approach, we derive a general expression for the four-dimensional (4D) TF correlation function (TFCF) of the proposed channel model. From this expression, we analyze the influence of the MSs' acceleration#…
