Incidents where external auditors do not issue a going concern audit opinion (GC opinion) to companies having severe financial problems have been reported globally. This issue motivated this study â (i) to investigate the effect of selected auditor characteristics in terms of specialization, tenure, and fee on GC opinion issuance and (ii) to examine the moderating effect of managementâs, familyâs, and institutionâs influence on the relationship between auditor characteristics and GC opinion issuance. The study involves 644 Malaysian financially distressed listed companies in the period 2006 to 2012. The results of a panel logistic regression analysis show that auditor characteristics have no relationship with GC opinion issuance. Influential management - measured as the level of their ownership - can dampen the positive relationship between auditor specialization and auditor tenure with GC opinion issuance. The presence of an influential family, on the other hand, can strengthen the positive relationship between auditor tenure and GC opinion. No evidence about an influential institutionâs impact on the GC opinion process could be found. In conclusion, while auditor characteristics do not affect the possibility of a GC opinion issuance, pressure imposed by influential management and family on the auditor during the audit opinion decision process does have an impact

This study examines the determinants of blockchain technology adoption in small and medium hospitality and tourism enterprises. This study also investigates the moderating effect of technology optimism. Results from a sample of 550 enterprises indicate that technological factors (i.e., relative advantage and compatibility), organizational factors (i.e., top management support, organizational readiness, and employee blockchain technology knowledge), and environmental factors (i.e., competitive pressure, customer pressure, and government support) positively affect intention to adopt blockchain technology. These relationships are moderated by technology optimism. Interestingly, perceived complexity and adoption cost are insignificant determinants of blockchain technology adoption. This study contributes to the literature by explaining the underlying mechanism and boundary conditions (i.e., managersâ technology optimism) under which technological, organizational, and environmental factors predict the adoption of blockchain technology among small and medium hospitality and tourism enterprises. Moreover, the findings provide implications for hospitality and tourism managers in adopting and implementing blockchain technologies.

As the retail industry continues to evolve in the digital era, businesses are exploring innovative solutions to enhance customer engagement and loyalty. This research proposes a novel approach to loyalty programs by leveraging blockchain technology to create a secure and transparent model for customer rewards. Traditional loyalty programs often face challenges related to security, transparency, and trust, leading to issues such as fraud and customer skepticism. The proposed model outlines the design and implementation of a blockchainbased loyalty program, ensuring a secure and immutable ledger for tracking customer transactions and rewards. Smart contracts, self-executing contracts with predefined rules, are utilized to automate and enforce the terms of the loyalty program, reducing the potential for disputes and enhancing transparency. The decentralized nature of the blockchain ensures that customer data is securely stored and accessible only to authorized parties, addressing privacy concerns prevalent in centralized loyalty systems. This research employs a mix of theoretical analysis and practical implementation to validate the feasibility and effectiveness of the blockchain-based loyalty program model. The proposed Ethereum Blockchain model stands out with a significantly higher throughput of 5300 transactions per day, accompanied by an exceptional transaction transparency score of 99.5 .

This study explores the adoption of cryptocurrency, specifically Bitcoin, in the Philippines. The authors argue that current behavioral prediction models, such as TRA, TPB, and TAM, do not adequately account for the affective constructs of decision-making when high monetary stakes are involved. To address this gap, the authors propose an integrative model that accounts for financial decision-making processes, risk constructs, and population-specific behavioral strategies. The study used a quantitative-based research design and involved 684 university students from one of the major state universities in the Philippines. The findings show that perceived usefulness, attitude toward cryptocurrency, self-efficacy, and descriptive norms significantly influenced the intention to adopt cryptocurrency. Overall, the study confirms the direct influence of instrumental attitude, knowledge of cryptocurrency, descriptive norm, risk tolerance, ease and difficulty, and control on an individualâs intention to use cryptocurrency. The study contributes to exploring a less studied Philippine consumer base and provides empirical findings and insights into Bitcoin adoption in developing Asian economies. JEL Classification: G15.

Purpose Problems such as information asymmetry and a lack of trust among construction practitioners damage the quality and progress of construction projects. The decentralization, transparency, traceability and temper-proof nature of blockchain technology (BCT) can provide solutions and facilitate multiparty cooperation. However, BCT acceptance in the construction industry is relatively low, and there are few pilot projects adopting BCT. Most relevant literature focuses on BCT acceptance at the industry and organizational levels, but the impact of non-managerial practitioners executing BCT or the traditional approach in day-to-day work tends to be disregarded. This study aims to establish a theoretical model of BCT acceptance, identify key influencing factors and paths of behavioral intention to adopt BCT and promote strategies to enhance BCT adoption. Design/methodology/approach A new BCT acceptance model for construction practitioners was proposed. A survey was performed with 203 construction practitioners in Shenzhen, China and post-survey interviews were conducted with four BCT experts for validation. Covariance-based structural equation modeling was used to examine the influence paths and moderating effect analysis was performed to check practitionersâ differential perceptions. Findings Performance expectancy, social influence, facilitating conditions and perceived behavioral control significantly and positively influence behavioral intention to accept BCT, while impacts from effort performance and risk are negative. Overcoming obstacles related to the effort required for BCT adoption and effective risk management will be essential to unlocking BCTâs transformative potential. Then, the moderating effects of respondentsâ gender, degree and BCT knowledge as well as the project type involved were analyzed. Continued adoption of BCT in the construction industry has the potential to revolutionize project management, transparency and trust among stakeholders. Research limitations/implications The findings of this research can help practitioners and government agencies understand crucial influencing factors and pathways of BCT acceptance. Targeted measures, such as increasing practitionersâ benefits and sense of BCT usefulness, conducting pilot projects and increasing publicity, were proposed for project leadership teams to enhance BCT adoption. This may lead to increased efficiency, reduced disputes and more streamlined and secure construction processes, ultimately enhancing the industryâs overall performance. Originality/value Few studies have explored BCT acceptance from the perspective of non-managerial construction practitioners. The BCT acceptance model proposed in this study is a novel adaptation of previous technology acceptance models, with new factors (risk and perceived behavioral control) and moderating variables (degree, BCT knowledge and project type) added for better understanding of non-managerial practitionersâ perceptions and differences.
This paper studies the adoption of blockchain technology under the scope of the Unified Theory of Acceptance and Use of Technology (UTAUT). Previous results on Management Information Systems (MIS) research are divergent about the significance of UTAUT variables in explaining the adoption behaviour of blockchain technology. The paper focuses on this specific concern and tries to contribute to existing studies by testing the model in a specific context (Tunisia) and by considering the individual variable âtrust in technologyâ as a mediating one. For this aim, a structural equation approach is adopted among 95 Tunisian professional respondents operating in technology-based sectors. The findings stipulate the importance of facilitating conditions and performance expectancy as drivers of the adoption intention. Additionally, the study reveals that trust in technology is significant in its mediating role in influencing the intention of adoption with the facilitating conditions and the social influence constructs. Moreover, the paper uncovers a direct relationship with the same variable. These findings provide valuable insights for both researchers and practitioners in understanding the factors that influence blockchain technology adoption in the Tunisian context and stress the indirect role of trust in technology with which decision-makers should be concerned.

Blockchain technology has become significant for financial sectors, especially digital payment systems, offering enhanced security, transparency, and efficiency. However, there is limited research on the factors influencing user trust in and acceptance of blockchain adoption in digital payment systems. This systematic review provides insight into the key factors impacting consumersâ perceptions and behaviours towards embracing blockchain technology. A total of 1859 studies were collected, with 48 meeting the criteria for comprehensive analysis. The results showed that security, privacy, transparency, and regulation are the most significant factors influencing trust for blockchain adoption. The most influential factors identified in the Unified Theory of Acceptance and Use of Technology (UTAUT) model include performance expectancy, effort expectancy, social influence, and facilitating conditions. Incorporating a trust and acceptance model could be a viable approach to tackling obstacles and ensuring the successful integration of blockchain technology into digital payment systems. Understanding these factors is crucial for creating a favourable atmosphere for adopting blockchain technology in digital payments. User-perspective research on blockchain adoption in digital payment systems is still insufficient, and this aspect still requires further investigation. Blockchain adoption in digital payment systems has not been sufficiently conducted from the userâs perspective, and there is a scope for it to be carried out. This review aims to shed light on the factors of trust in and acceptance of blockchain adoption in digital payment systems so that the full potential of blockchain technology can be realised. Understanding these factors and their intricate connections is imperative in fostering a conducive environment for the widespread acceptance of blockchain technology in digital payments.

Purpose Cryptocurrencies are becoming increasingly attractive as alternatives to traditional currencies. Although many retailers accept cryptocurrencies as a means of payment in online shopping, consumersâ cryptocurrency adoption intention in online shopping (CCAI) is still low. This study aims to investigate the influence of attitudes, subjective norms, consumer trust, financial literacy and fear of missing out (FOMO) on CCAI. Design/methodology/approach A quantitative research approach was followed using a consumer survey. Hypothesized relationships were tested through regression and mediation analyses. Findings The results revealed that consumers could accept cryptocurrencies as a means of payment in online shopping. Attitudes, subjective norms, consumer trust and financial literacy directly and positively influence CCAI, while they indirectly affect CCAI through the mediating impact of FOMO. Practical implications Marketing managers should improve consumersâ knowledge about cryptocurrencies and trust in online shopping to increase CCAI. Social media marketing can be appropriate, while the advertising content can address keeping up with others and staying connected. Originality/value This study addresses a critical gap in the literature by empirically examining the antecedents of CCAI within an original conceptual model based on the theoretical framework provided by the theory of planned behavior. Attitudes, subjective norms, trust and financial literacy influence CCAI, where FOMO plays a significant role as a mediator.
Blockchain has been hyped and considered a potential game-changer for the recording of accounting transactions as it enables triple-entry accounting and real-time reporting. However, there is very little knowledge of the uptake of blockchain in accounting, and most blockchain accounting research is conceptual, lacking empirical evidence. This study addresses this gap and examines the organisational factors that drive and hinder the adoption of blockchain in accounting, as well as the perceived benefits. Using the technology-organisation-environment (TOE) framework, we analyse interview data collected from blockchain experts and accountants (N = 19). The findings confirm the influence of nine context-specific factors, highlighting the challenges and lack of knowledge in understanding the usage and benefits of blockchain in accounting, its complex integration with existing accounting systems, and the increased costs associated with the adoption intention. This study provides novel empirical evidence of the factors by adequately contextualising an established theoretical framework in the context of accounting. The findings are useful for practitioners and the broader accounting information systems research community as they provide empirical insights into how context-specific factors influence blockchain adoption in accounting.
The rapid expansion of advanced technology has made available, the progress of novel approaches to improve the way student information systems are maintained in every institute/university. Every university has crucial data of students that needs to be protected. It's a step towards a sustainable future. Currently, most universities use a centralized method of data storage, which increases the risk of data tampering. With the rise of digitization, it is vital for universities to accept technological change to maintain a stronger Student Information System. Blockchain is one such technology model. Blockchain is a distributed ledger that makes it possible to record every Node-to-Node transaction lacking the aid of a central authority. It is found that few organizations hesitate to adopt and diffuse the Blockchain technology. In India it is found that very less focus is given to exposure of new technologies and its implementation with context to education sector. An assessment of use cases is feasible to assist direct the decision to adopt Blockchain in university information systems by offering a conceptual blended interdependence model that contains pertinent factors. The basis of the research is to spot the individual factors that determine universitiesâ resolution to use Blockchain. Two factors, namely Use behavior and Intention to use, of universities are investigated by using a combo model of TAM and UTAUT. The research methodology adopted is both Qualitative and Quantitative method. The analysis involved statistical assessments including correlation analysis, multiple regression analysis, and Chi-square tests. The findings indicate a strong correlation between the elements of UTAUT and TAM factors and the adoption of blockchain technology by universities in their usage behavior. This study also presents an opportunity to universities to benefit from the guidelines on how to implement Blockchain in managing the university information system.
The use of blockchain technology (BT) is transforming consumer behavior and enhancing business values, but its role in the context of mobile food delivery applications (MFDAs) is underexplored. Therefore, this study utilizes stimulusâorganismâresponse theory to determine consumers' willingness to pay more (WPM) and behavioral intention to use BT-enabled MFDAs. The empirical analysis was conducted using the structural equation modeling approach. The findings establish that traceability, transparency, and privacy assurance positively influence consumers' perceived values. Furthermore, IT knowledge positively moderates the relationships between privacy assurance, traceability, and perceived value. Further, perceived value positively impacts WPM and behavioral intention. Finally, consumers' trust in BT moderates the relationships between perceived value, WPM, and behavioral intention to use BT-enabled MFDAs. MFDA platforms should ensure the applicability of BT on a priority basis and operationalize it to meet consumersâ needs and demands.

Tax evasion is a major issue for authorities worldwide. Understanding the factors that influence individuals' intrinsic motivation to pay taxes, known as their tax morale, is important for improving tax compliance. This study investigated gender differences in judging tax evasion in the context of cryptocurrency trading. Specifically, a survey study explored whether different moral foundations, financial literacies, and political orientations among females vs. males might explain potential gender differences in judging tax evasion. In an online survey, 243 U.S. adults read a vignette about a friend evading taxes in a cryptocurrency trading context. In a correlational analysis, we found that females judged tax evasion harsher, as being more morally wrong than males. Of the psychographic factors, only individualizing moral foundation values (i.e., fairness and harm avoidance) explained the harsher moral judgment by females. That is, individualizing moral foundation values were at a higher level among females, which further predicted females' harsher judgment of tax evasion. While females also had, on average, lower financial literacy and knowledge of cryptocurrencies than males, these did not predict their harsher judgment of tax evasion. The findings contribute to research on gender differences in moral judgments and highlight that a given transgression, or a specific crime, may violate different moral values in men and women. The results demonstrate to policy makers that it is important to take into account gender differences, in campaigns promoting tax morale and compliance.
In healthcare systems, blockchain technology plays a crucial role in transmitting COVID-19 data among multiple entities.Over time, various blockchain-based medical applications have emerged to handle medical information confidentially.One such system is the Scalable eHealthChain system (SeHealthChain), which utilizes a sharding scheme consisting of transaction chain and reputation chain structures to enhance throughput and security.However, the system employs a modified Raft-based Synchronous Consensus Scheme (RSCS) for generating the transaction blockchain, which can potentially introduce illegitimate transactions to the Hyperledger fabric network if a rogue node transfers them to the orderer.This poses a significant security risk in the worst-case scenarios.Additionally, as the hash rate fluctuates exponentially, the generation period of transaction blocks and computation difficulty increase.To address these issues, this article proposes an Optimized SeHealthChain (OSeHealthChain) system.It integrates a Tuna Swarm Optimization Algorithm (TSOA) with the modified RSCS to dynamically adjust the blockchain parameters in response to significant changes in the hash rate.The TSOA optimizes two variables, namely the Block Interval (BI) and Difficulty Adjustment Interval (DAI) of the Proof-of-Work (PoW) for the transaction blockchain, based on objective functions that consider the Standard Deviations (SD) of the mean BI and difficulty.By selecting appropriate variables, the system generates new transaction blocks with minimal nodes and overhead, effectively validating transactions and blocks to enhance the security level.Extensive simulations show that the OSeHealthChain achieves a throughput of 3918tps and a user-perceived latency of 63.8s for 1000 nodes, outperforming the SeHealthChain, eHealthChain, Permissionless Proof-of-Reputation-X (PL-PoRX), and hybrid Proof of Stake-Practical Byzantine Fault Tolerance (POS-PBFT) algorithms in blockchain systems.It also achieves throughputs of 7051tps, 6418tps, and 6290tps for simple, camouflage, and observe-act attacks, respectively, with 1000 nodes and a shard dimension of 200 during 20 epochs.
