The impact of online brand community characteristics on customer engagement: An application of Stimulus-Organism-Response paradigm

The advent of interactive digital platforms has led people to progressively interact on such platforms, urging organizations to create online communities to engage customers with them and with each other to enhance brand loyalty. This study attempts to investigate what motivates customers to engage in these brand communities. Through a questionnaire survey of 430 Facebook users, this study investigates whether and how the unique characteristics (information quality, system quality, virtual interactivity, and rewards) of online brand communities affect customer engagement. The consequent effect of customer engagement on brand loyalty is also examined. This study frames and empirically validates a model for engaging customers with online brand communities on Facebook, considering the moderating role of gender. The Stimulus-Organism-Response paradigm is solicited to justify the theoretical background of this study. The data were analyzed using structure equation modelling. Results reveal that each of the characteristics positively influences customer engagement, with information quality and virtual interactivity bearing the strongest influence. Customer engagement also exhibits a strong positive impact on brand loyalty. This results further reveal that gender gap in the online environment is declining as the impact of all the four characteristics of online brand communities on customer engagement was invariable across male and female members.

Social support,belongingness, and value co-creation behaviors in online health communities

Community members become part of the value chain, and their value co-creation behaviors have progressively elicited extensive attention from scholars and practitioners. However, the mechanisms on how members co-create value in online health communities (OHCs) have been poorly investigated. Therefore, this study develops a model of how belongingness and social support affect the four value co-creation behaviors (i.e., information sharing, responsible, feedback, and advocacy behaviors) in OHCs based on need-to-belong theory and social support literature. Our survey data from 237 OHC members empirically show that informational, emotional, esteem, and companionship supports positively influence members’ belongingness to OHCs, which in turn affects information sharing, responsible, feedback, and advocacy behaviors. Members’ belongingness to OHCs mediates the relationships between the four forms of social support and value co-creation behavior. In addition, OHC members’ perceived health competence positively moderates the influence of belongingness on information-sharing behavior, whereas their mental health negatively moderates the relationships of belongingness with all four value co-creation behaviors. Therefore, promoting value co-creation relies on the improvement of member belongingness, but it should also consider the health competence and status of members.     

Research on cross-chain and interoperability for blockchain system

At present, there is an urgent need for blockchain interoperability technology to realize interconnection between various blockchains, data communication and value transfer between blockchains, so as to break the ‘ value silo’ phenomenon of each blockchain. Firstly, it lists what people understand about the concept of interoperability. Secondly, it gives the key technical issues of cross-chain, including cross-chain mechanism, interoperability, eventual consistency, and universality. Then, the implementation of each cross-chain key technology is analyzed, including Hash-locking, two-way peg, notary schemes, relay chain scheme, cross-chain protocol, and global identity system. Immediately after that, five typical cross-chain systems are introduced and comparative analysis is made. In addition, two examples of cross-chain programmability and their analysis are given. Finally, the current state of cross-chain technology is summarized from two aspects: key technology implementation and cross-chain application enforcement. The cross-chain technology as a whole has formed a centralized fixed mechanism, as well as a trend of modular design, and some of the solutions to mature applications were established in the relevant standards organizations, and the cross-chain technology architecture tends to be unified, which is expected to accelerate the evolution of the open cross-chain network that supports the real needs of the interconnection of all chains.

A notary group-based cross-chain mechanism

As an emerging distributed technology, blockchain has begun to penetrate into many fields such as finance, healthcare, supply chain, intelligent transportation. However, the interoperability and value exchange between different independent blockchain systems is restricting the expansion of blockchain. In this paper, a notary group-based cross-chain interaction model is proposed to achieve the interoperability between different blockchains. Firstly, a notary election mechanism is proposed to choose one notary from the notary group to act as a bridge for cross-chain transactions. Secondly, a margin pool is introduced to limit the misconduct of the elected notary and ensure the value transfer between the involved blockchains. Moreover, a reputation based incentive mechanism is used to encourage members of the notary group to participate in cross-chain transactions. Ethereum-based experiments demonstrate that the proposed mechanism can provide an acceptable performance for cross-chain transactions and provide a higher security level than ordinary cross-chain mechanisms.     

Posting-related attributes driving differential engagement behaviors in online travel communities

Users’ engagement behaviors such as likings, sharing and social interactions in online communities are critically important to the viability and the ultimate success of these communities. However, empirical research investigating which posting-related attributes driving these participation behaviors still lags. The purpose of this study is to understand what and how posting-related attributes drive the engagement behaviors. Using travelogue data from a large traveling knowledge-sharing community, we used econometric models to investigate and compare the antecedents leading to three different kinds of engagement behavior that users exhibit in online communities (i.e., consuming, contributing, and creating). The results reveal that five attributes are associated with these engagement behaviors. These attributes demonstrate the differential effectiveness on the engagement behaviors with different intensities. Our empirical findings provide both theoretical and practical implications for online community operators to build a vibrant and successful online community.     

A blockchain-enabled wiki framework based on participatory design

The 5G mobile Internet facilitates contents generation for online communities and platforms through human-to-human collaboration. Wikipedia, a well-known online community, uses wiki technology to build an encyclopedia through collective intelligence and collaboration. Mainstream wiki systems adopt a centralized implementation, and while existing studies have optimized the efficiency of the wiki systems' centralized implementation, these systems still suffer from a lot of problems, for example, opacity and distrust. Over the years, blockchain has brought a flurry of fervour and decentralization to the system architecture, meanwhile giving users a sense of trust and participation. Thus, an innovative blockchain-enabled wiki framework called DecWiki is proposed to build one transparent, truthful, collaborative and autonomous encyclopedia. After several participatory design iterations, we present DecWiki's detailed architecture and its implementation in the form of a smart contract and use the interplanetary file system to complement the big data storage. Meanwhile, we use the trusted execution environment to secure sensitive information in the wireless scenario. Finally, the system overhead and the acceptance of the prototype are evaluated. Extensive experiments present its significant performance.

Digital healthcare technology adoption by elderly people: A capability approach model

Digital technologies, such as online healthcare portals, enable elderly people to live independently at home for a longer period of time. Independent living, in this context, refers to the freedom elderly people have to live their lives in ways that they find important. Borrowing from the capability approach (CA) framework from Nobel Prize winner Amartya Sen, the core argument of this paper is that elderly people make decisions on whether to use digital healthcare technologies by considering how these technologies enhance their capabilities to live their lives in ways that are valuable to them. This paper develops a theoretical model of adoption of digital healthcare technologies that support independent living applying the CA framework. We follow a mixed-methods approach with a sequence of qualitative, quantitative, and qualitative methods. We find support for our theoretical model, specifically that the intention to use online healthcare portals depends on whether elderly people expect to enhance their capabilities for living independently by using them. Our study contributes to the information systems literature on adoption of digital healthcare technologies as it is the first that applies the capability approach. For adoption studies on digital technologies in healthcare and beyond, our study poses two major theoretical implications: (1) when considering how outcome expectations affect adoption, scholars should consider how digital technologies allow people to live their lives in ways that are valuable to them, rather than considering how technologies help to execute predefined tasks, jobs, or activities; (2) the availability of digital technologies should be considered as a mediator between outcome expectations and intention to use technologies.

Compliance to personal data protection principles: A study of how organizations frame privacy policy notices

This study examines how organizations in Malaysia frame their privacy policy notice to comply with the Personal Data Protection Act (PDPA, 2010) and if these organizations differ in their level of compliance and the readability of their privacy notices. We collected the online privacy polices of 306 organizations from 12 sectors to assess their readability and compliance with PDPA requirements. The results show that private-owned organizations have higher compliance level compared to public-owned organizations. Sectors that hold more personal sensitive data obtain higher compliance scores. Non-governmental organizations demonstrate higher compliance level compared to government-owned organizations. Despite differences in the compliance scores, most organizations fail to meet the requirements of the PDPA. Our study also reveals that readability has a negative correlation with the compliance score because simple and shorter version of the privacy policies often lack detailed information. Our findings provide valuable insights into organizations’ privacy policy compliance across different sectors in Malaysia. Specifically, the Malaysian authority should implement more effective mechanisms to enforce the compliance of the PDPA. Organizations should also take corrective actions to improve the compliance scores of their online privacy policies.

Modelling upper echelons’ behavioural drivers of Green IT/IS adoption using an integrated Interpretive Structural Modelling – Analytic Network Process approach

The purpose of this paper is to understand and identify various psychological drivers which motivate managers of organizations to adopt Green information technology (Green IT) and Green information system (Green IS) within their corporations. These psychological factors are modelled through the lens of Upper Echelon Theory (UET) to study their interrelationship and interdependency and further prioritize them to strategize appropriate managerial actions. The factors were identified through an exhaustive literature review and further confirmed by the experts in the field. A hybrid Interpretive Structural Modelling – Analytic Network Process (ISM-ANP) approach has been adopted to establish the complex interrelationship among the psychological drivers and further to cluster and prioritize them. The main contribution of this study is composing directions and dominance of various psychological drivers to enhance decision-making process of managers towards the adoption of Green IT/IS. As long as decisions are made by individuals within organizations, this paper forms the basis of identifying individual-level factors important in motivating managers towards Green IT/IS adoption. The results of this study would help organizations and policy makers to understand and develop strategies to target and select an individual for managerial position with mind-set more towards environmental sustainability and Green IT/IS concepts. By applying the proposed methodology, organizations can classify and prioritize their action plans such as several educational methods to reinforce, foster and incline psychological factors to motivate their individuals to behave proenvironmentally and practice Green IT/IS initiatives to enhance environmental sustainability of their corporations.     

Activating knowledge through electronic collaboration: vanquishing the knowledge paradox

Electronic collaboration has become a driver for productivity as organizations develop linkages for the planning, sourcing, and execution of goods and services. These organizations require mechanisms to harness the diverse and personalized intellectual resources that are distributed across the world. While electronic collaboration technologies have made it possible to harness intellectual resources across space and time, knowledge management is locked in a paradox of perception-the more valuable a knowledge resource is seen to be, the less it is shared. This paper develops a framework for the activation of knowledge that relies on a view of knowledge-as-identity. The analysis of a case study reveals "activation conditions" that delineate processes in which electronic collaboration technologies can be most effective. This has implications for the creation of collaborative work environments that enhance knowledge activation in organizations.
