Purpose The purpose of this paper is to present a concept of the protocol for public registries based on blockchain. New database protocol aims to use the benefits of blockchain technologies and ensure their interoperability. Design/methodology/approach This paper is framed with design science research (DSR). The primary method is exaptation, i.e. adoption of solutions from other fields. The research is looking into existing technologies which are applied here as elements of the protocol: Name-Value Storage (NVS), Berkley DB, RAID protocol, among others. The choice of NVS as a reference technology for creating a database over blockchain is based on the analysis and comparison with two other similar technologies Bigchain and Amazon QLDB. Findings The proposed mechanism allows creating a standard database over a bundle of distributed ledgers. It ensures a blockchain agnostic approach and uses the benefits of various blockchain technologies in one ecosystem. In this scheme, blockchains play the role of journal storages (immutable log), whereas the overlaid database is the indexed storage. The distinctive feature of such a system is that in blockchain, users can perform peer-to-peer transactions directly in the ledger using blockchain native mechanism of user access management with public-key cryptography (blockchain does not require to administrate its database). Originality/value This paper presents a new method of creating a public peer-to-peer database across a bundle of distributed ledgers.

Role Of Information

Purpose – The purpose of this paper is to investigate the face-to-face citizen service encounter in public administrations’ front offices, and present a novel qualification approach to empower service personnel on-the-job, and thereby deepen the knowledge on the role of information and communication technology for advancing governmental reforms. Design/methodology/approach – The presented study follows a design science research methodology, conducted in collaboration with the public administration of a major German city. Data were collected using multiple quantitative and qualitative methods, including questionnaires, semi-structured interviews and video analysis. Findings – A novel on-the-job qualification approach for empowering public employees in their job-related skills, building on the concept of affordances, is developed. Thereto, six design principles for equipping artifacts with counseling affordances are presented. Evaluations in real-world environments provide first evidence that “learning with counseling affordances” constitutes an effective qualification measure to initiate experiential learning on-the-job, helping employees in the resource-restricted work environment of public front offices to obtain the skills to provide superior advisory services. Research limitations/implications – The “learning with counseling affordances” approach was developed in collaboration with an individual major German city and the paper provides first evidence of its effectiveness and suitability. Hence, the study’s insights should be approved by further research to strengthen generalizability. Originality/value – The paper highlights the previously neglected aspects of employee’s skills and qualification for promoting governmental transformation. By highlighting the beneficial relationship between affordances and on-the-job learning, the paper provides novel insights on the role of information and communication technology to promote governmental transformation.

Purpose This paper aims to investigate the use of crowdsourcing in the enhancement of an ontology of taxonomic knowledge. The paper proposes a conceptual architecture for the incorporation of crowdsourcing into the creation of ontologies. Design/methodology/approach The research adopted the design science research approach characterised by cycles of “build” and “evaluate” until a refined artefact was established. Findings Data from a case of a fruit fly platform demonstrates that online crowds can contribute to ontology enhancement if engaged in a structured manner that feeds into a defined ontology model. Research limitations/implications The research contributes an architecture to the crowdsourcing body knowledge. The research also makes a methodological contribution for the development of ontologies using crowdsourcing. Practical implications Creating ontologies is a demanding task and most ontologies are not exhaustive on the targeted domain knowledge. The proposed architecture provides a guiding structure for the engagement of online crowds in the creation and enhancement of domain ontologies. The research uses a case of taxonomic knowledge ontology. Originality/value Crowdsourcing for creation and enhancement of ontologies by non-experts is novel and presents opportunity to build and refine ontologies for different domains by engaging online crowds. The process of ontology creation is also prone to errors and engaging crowds presents opportunity for corrections and enhancements.

Purpose Knowledge acquired from sources of unverified information such as gossip, partial truths or lies, in this paper it is termed as “counter-knowledge.” The purpose of this paper is to explore this topic through an exploration of the links between a Hospital-in-the-Home Units (HHUs) learning process (LP), counter-knowledge, and the utilization of communication technologies. The following two questions are addressed: Does the reduction of counter-knowledge result in the utilization of communication technologies? Does the development of counter-knowledge hinder the LP? Design/methodology/approach This paper examines the relevance of communication technologies to the exploration and exploitation of knowledge for 252 patients of a (HHU) within a Spanish regional hospital. The data collected was analyzed using the PLS-Graph. Findings To HHU managers, this study offers a set of guidelines to assist in their gaining an understanding of the role of counter-knowledge in organizational LPs and the potential contribution of communication technologies. Our findings support the proposition that the negative effects of counter-knowledge can be mitigated by using communication technologies. Originality/value It is argued in this paper that counter-knowledge may play a variety of different roles in the implementation of LPs. Specifically, the assignment of communication technologies to homecare units has given them the means to filter counter-knowledge and prevent users from any possible problems caused by such counter-knowledge.

Purpose The extant literature has mixed results regarding the credit card cue effect. Some showed that credit card cues stimulate spending, whereas others were unable to replicate the findings or found that cues discourage consumer spending. The purpose of this paper is to investigate how consumers’ sensitivity to the pain of payment affects their mental associations about credit cards and how the differences in credit card associations moderate the credit card cue effect on spending, providing a possible explanation for the mixed results in the literature. Furthermore, this paper examines the role of consumers’ perceived financial well-being, measured by their perceptions of current and future wealth and their sense of financial security, in mediating this moderation effect. Design/methodology/approach An experimental study was conducted with a sample of 337 participants to test the hypothesized model. Findings After being shown credit card cues, spendthrift participants had more spending-related thoughts and less debt-related thoughts, perceived themselves as having better financial well-being and consequently spent more than tightwad participants. Originality/value To the authors’ knowledge, this is the first study to investigate the direct link between an exposure to credit card cues and perceived financial well-being, and one of the few to show evidence of the moderating effect of consumers’ sensitivity to the pain of payment on spending when credit card cues are present. This study suggests that marketers may use credit card cues to promote consumer spending, whereas consumers, especially spendthrifts, should be aware of how credit card cues may inflate their perceived financial well-being and stimulate them to spend more.

PurposeBy drawing on commitment-trust theory, we examine the role of swift trust and distrust in supporting coopetition under conditions of uncertainty and interdependence in the setting of humanitarian disaster relief organisations.Design/methodology/approachThis paper presents findings from case studies of 18 international humanitarian relief organisations based on 48 interviews and the analysis of publicly available documents.FindingsWe find that both swift trust and swift distrust support coopetition. As coopetition is simultaneous cooperation and competition, in this study we show how swift trust and swift distrust also occur simultaneously in coopetitive contexts.Research limitations/implicationsCoopetition as a strategic choice is well-researched in the private sector, yet has received less attention in the nonprofit sector, particularly in contexts that are shaped by interdependence and uncertainty. We show the importance of swift trust and swift distrust in coopetitive relationships by drawing on commitment-trust theory.Practical implicationsIn focusing on a competitive environment in which cooperation is essential, we find limited choice of coopetitive partners. Humanitarian relief organisations must often simply work with whichever other organisations are available. We highlight how trust and distrust are not opposite ends of a spectrum and detail how both contribute to coopetitive relationships.Originality/valueOur findings contribute to commitment-trust theory by explaining the important role of distrust in forging coopetitive relationships. Furthermore, we contribute to prior work on coopetition by focusing on an uncertain and interdependent nonprofit environment.

Purpose The purpose of this paper is to address the confusing use of terminology associated with tourism undertaken by Muslims and to identify key concerns associated with this type of tourism. Design/methodology/approach This is an exploratory study and adopts a critical review of literature following the evolutionary concept analysis method. Content analysis of popular UK media, UK-based tour operators’ websites and tourism strategies of destinations popular with Muslim tourists were conducted to examine the use of terminology. Findings There is no clear difference between the various terms (halal, Muslim friendly, Islamic, etc.) used. Overall, academia uses the term Islamic tourism, while the industry and media use various terms. Among destinations, however, there is no clear and consistent use of terminology. A key concern of Islamic tourism is the role of certification in assuring travellers and the lack of standardisation of halal certification. Research limitations/implications The paper is based on literature review and secondary data analysis. It lacks primary research. Practical implications This study highlights the need for consistent use of terminology across industry. Another implication is the issue surrounding halal certification of food and the importance of trust in the seller/service provide. Another trend that industry providers need to consider is the growth of the Muslim millennial traveller and the needs of this market segment. Originality/value The paper highlights the importance of studying the Muslim tourist market and provides a starting point for further research. It highlights several issues such as the need to develop a typology of Muslim tourists. Of particular interest is the concern whether halal values in danger of being commodified in the absence of a universal agreed criterion for halal certification.
