PurposeThe aim of this study is to explore and establish the relationships between justice dimensions, expectation-confirmation model (ECM) and continuance intention and also to examine the mediating effect of learners’ satisfaction and perceived usefulness toward continuance intentions of the university learning management system (LMS) within open and distance learning (ODL) context.Design/methodology/approachA cross-sectional research design was used, and the data were collected from a sample of 366 respondents utilizing the online survey questionnaire approach. Hypotheses were tested using the partial least square (PLS) SEM technique.FindingsThe findings reveal that justice dimensions (distributive, procedural, interpersonal and informational justice) have a significant relationship with learners’ satisfaction. Performance confirmation have significant relationship with learners’ satisfaction and perceived usefulness. Perceived usefulness has a direct significant relationship toward learners’ satisfaction, and learners’ satisfaction has a direct significant relationship toward continuance intention. For mediation analysis, learners’ satisfaction was found to have a mediation effect in the relationship between the justice dimensions and continuance intention. Learners’ satisfaction was also found to have a mediation effect on the relationship between performance conformation and continuance intention. However, learners’ satisfaction was found not to have a mediation effect on the relationship between perceived usefulness and continuance intention, and perceived usefulness does not have a mediation effect in the relationship of performance confirmation and learners’ satisfaction.Originality/valueThis study advances knowledge and provides valuable insights to practitioners and academic scholars to have a better understanding of the effective attributes of the university LMS, and also to maximize the revenues and the sustainability of the institutions in long term, especially in the 21st century.

Big data analytics capability and contribution to firm performance: the mediating effect of organizational learning on firm performance
Authors: Garmaki Mahda , Gharib Rebwar Kamal , Boughzala Imed 
Published: May 2023

PurposeThe study examines how firms may transform big data analytics (BDA) into a sustainable competitive advantage and enhance business performance using BDA. Furthermore, this study identifies various resources and sub-capabilities that contribute to BDA capability.Design/methodology/approachUsing classic grounded theory (GT), resource-based theory and dynamic capability (DC), the authors conducted interviews, which involved an exploratory inductive process. Through a continuous iterative process between the collection, analysis and comparison of data, themes and their relationships appeared. The literature was used as part of the data set in the later phases of data collection and analysis to identify how the study’s findings fit with the extant literature and enrich the emerging concepts and their relationships.FindingsThe data analysis led to developing a conceptual model of BDA capability that described how BDA contributes to firm performance through the mediated impact of organizational learning (OL). The findings indicate that BDA capability is incomplete in the absence of BDA capability dimensions and their sub-dimensions, and expected advancement will not be achieved.Research limitations/implicationsThe research offers insights on how BDA is converted into an enterprise-wide initiative, by extending the BDA capability model and describing the role of per dimension in constructing the capability. In addition, the paper provides managers with insights regarding the ways in which BDA capability continuously contributes to OL, fosters organizational knowledge and organizational abilities to sense, seize and reconfigure data and knowledge to grab digital opportunities in order to sustain competitive advantage.Originality/valueThis article is the first exploratory research using GT to identify how data-driven firms obtain and sustain BDA competitive advantage, beyond prior studies that employed mostly a hypothetico-deductive stance to investigate BDA capability. While the authors discovered various dimensions of BDA capability and identified several factors, some of the prior related studies showed some of the dimensions as formative factors (e.g. Lozada et al., 2019; Mikalef et al., 2019) and some other research depicted the different dimensions of BDA capability as reflective factors (e.g. Wamba and Akter, 2019; Ferraris et al., 2019). Thus, it was found necessary to correctly define different dimensions and their contributions, since formative and reflective models represent various approaches to achieving the capability. In this line, the authors used GT, as an exploratory method, to conceptualize BDA capability and the mechanism that it contributes to firm performance. This research introduces new capability dimensions that were not examined in prior research. The study also discusses how OL mediates the impact of BDA capability on firm performance, which is considered the hidden value of BDA capability.

Authors: Ahmad Amouei Mahdieh , Valmohammadi Changiz , Fathi Kiamars 
Published: May 2023

PurposeIn the digital age, emerging technologies have affected every industry. Information and communications technology and digital technologies have transformed traditional supply chains into smart and more resilient ones, enabling effective management of challenges. Given the importance of the two topics, namely sustainable supply chain management and Industry 4.0 in supply chain management, on the one hand, and the dearth of theoretical research performed in this area on the other, this study aims to propose a conceptual model on a sustainable digital supply chain management in manufacturing companies.Design/methodology/approachThis study utilized a qualitative approach. First, an in-depth review of the relevant literature was done. Then, following a multi-grounded theory methodology, relevant data were gathered by reviewing 92 papers and conducting nine semi-structured interviews with industry experts. These data were analyzed using the MAXQDA software.FindingsA total of 41 concepts, ten sub-components and three main components (dimensions) were extracted, and the proposed conceptual model was presented. Finally, based on this conceptual model, three propositions were suggested.Research limitations/implicationsConsidering that the present study was performed in the context of Iranian manufacturing companies, caution should be exercised in relation to the generalizability of the obtained results. Also, due to the problems in the digital technology infrastructure and the limited use of these technologies by manufacturing companies (emphasized by the interviewees), this study focused on the theoretical dimension of using digital technologies by these companies.Practical implicationsThe proposed comprehensive model can help academicians as well as practitioners to focus better and explore the variables and constructs of the model, paving the way toward successful implementation of digital technologies in the manufacturing supply chain.Originality/valueTo the best knowledge of the authors, this study is among the first of its kind which presents a holistic and comprehensive digital supply chain model aimed at guiding companies to consider sustainability from all the main dimensions and their relevant indicators.
Global hidden factors predicting financial distress in Gulf Arab states: a quantile–time–frequency analysis
Authors: Trabelsi Nader 
Published: May 2023

PurposeThis study aims to uncover the main predictors of financial distress in the Gulf Cooperation Council (GCC) countries using a wide range of global factors and asset classes.Design/methodology/approachThis study uses novel approaches that take into account extreme events as well as the nonlinear behavior of time series over various time intervals (i.e. short, medium and long term) and during boom and bust episodes. This study primarily uses the conditional value at risk (CoVaR), the quantile multivariate causality test and the partial wavelet coherence method. The data collection period ranges from March 2014 to September 2022.FindingsUS T-bills and gold are the primary factors that can increase financial stability in the GCC region, according to VaRs and CoVaRs. More proof of the predictive value of the oil, gold and wheat markets, as well as geopolitical tensions, uncertainty over US policy and volatility in the oil and US equities markets, is provided by the multivariate causality test. When low extreme quantiles or cross extreme quantiles are taken into account, these results are substantial and sturdy. Lastly, after adjusting for the effect of crude oil prices, this study’s wavelet coherence results indicate diminished long-run connections between the GCC stock market and the chosen global determinants.Research limitations/implicationsDespite the implications of the author’s research for decision makers, there are some limitations mainly related to the selection of Morgan Stanley Capital International (MSCI) GCC ex-Saudi Arabia. Considering the economic importance of the Kingdom of Saudi Arabia (KSA) in the region, the author believes that it would be better to include this country in the data to obtain more robust results. In addition, there is evidence in the literature of the existence of heterogeneous responses to global shocks; some markets are more vulnerable than others. This is another limitation of this study, as this study considers the GCC as a bloc rather than each country individually. These limitations could open up further research opportunities.Originality/valueThese findings are important for investors seeking to manage their portfolios under extreme market conditions. They are also important for government policies aimed at mitigating the impact of external shocks.
Investigation of effective factors on WOM in the context of reasoned action theory of tourists preferring local restaurants: Afyonkarahisar case
Authors: Baydeniz Erdem , Türkoğlu Turgut , Aytekin Engin , Pamukcu Hüseyin , Sandikci Mustafa 
Published: May 2023

PurposeThis study attempts to ascertain how behavioral intention and word-of-mouth communication is affected by belonging, attitude toward behavior and subjective norm found in the theory of reasoned action. The research universe consists of customers visiting local restaurants operating in Afyonkarahisar.Design/methodology/approachThe survey technique was used to collect data from customers visiting local restaurants between 05 September and 05 November 2022, using the convenience sampling method. The acquired data (n = 385) were analyzed using the structural equation model and the SmartPLS statistical tool.FindingsThe study findings indicate that behavioral intention is positively and significantly influenced by behavioral attitude, subjective norm and behavioral norm, but not by belonging. However, behavioral intention significantly and favorably influences word-of-mouth. When the indirect effect of study findings was analyzed, it was showcased that behavioral intention and attitude indirectly influence subjective norm and word-of-mouth communication, but belonging has no such effect.Practical implicationsThe results suggest that businesses should focus on using local products as customers have a positive attitude toward them and provide customers with a sense of belonging to increase word-of-mouth communication. Additionally, the study highlights the importance of subjective norms in shaping customers' intentions and behavior toward local products.Originality/valueThe contribution of this article is valuable in terms of meeting this quest of visitors who have the motivation to introduce and experience the local culture, especially the Reasoned Action Theory of Word-of-Mouth communication approach of the customers, who play an essential role in the promotion and marketing of local restaurants selling local products, and to make a difference in their travels. Findings indicate that businesses should use local products, and customers need a sense of belonging. However, there is a subjective norm and attitude toward local products, and they should provide the necessary tendencies to gain a sense of belonging.

Authors: Sultan Nasir , Mohamed Norazida , Martin Mervyn , Latif Hafizah Mohd 
Published: May 2023

Purpose
This study aims to examine the Financial Action Task Force’s recommendations on virtual currencies (VCs) and how Pakistan has responded to them.

Design/methodology/approach
Qualitative document and jurisprudence analysis techniques were used to achieve the study’s goal.

Findings
According to this study, VCs are modern FinTech that no jurisdiction can ignore. However, Pakistan has not adopted regulations to govern VCs but comprehensively prohibits their use. It is primarily due to the apathy of various regimes and regulators. Furthermore, the geographical location, undocumented economy and rampant corruption could facilitate the abuse of VCs for money laundering.

Originality/value
This study has provided a significant overview for developing regulations for VCs in Pakistan and other developing jurisdictions with the same characteristics.
Wikipedia and large language models: perfect pairing or perfect storm?
Authors: Thomas Paul A. 
Published: May 2023

Purpose
The purpose of this paper is to explore the potential benefits and challenges of using large language models (LLMs) like ChatGPT to edit Wikipedia.

Design/methodology/approach
The first portion of this paper provides background about Wikipedia and LLMs, explicating briefly how each works. The paper's second section then explores both the ways that LLMs can be used to make Wikipedia a stronger site and the challenges that these technologies pose to Wikipedia editors. The paper's final section explores the implications for information professionals.

Findings
This paper argues that LLMs can be used to proofread Wikipedia articles, outline potential articles and generate usable Wikitext. The pitfalls include the technology's potential to generate text that is plagiarized or violates copyright, its tendency to produce “original research” and its tendency to generate incorrect or biased information.

Originality/value
While there has been limited discussion among Wikipedia editors about the use of LLMs when editing the site, hardly any scholarship has been given to how these models can impact Wikipedia's development and quality. This paper thus aims to fill this gap in knowledge by examining both the potential benefits and pitfalls of using LLMs on Wikipedia.

Authors: Bian Fuping , Lin Shudong 
Published: May 2023

Purpose
This paper aims to investigate the effects on coatings performance in the epoxy silicone resin system owing to the existence of the different chain length of open-chain epoxy monomer. In this paper, [4-Methylphenyl-(4–(2-methylpropyl) phenyl)]iodonium as photoinitiator was added into epoxy silicone resin by ultraviolet (UV)-cured polymerization to investigate the effects on coatings performance owing to the existence of the different chain length of open-chain epoxy monomer.

Design/methodology/approach
A simple hydrosilylation reaction was used to synthesize epoxy-based silicone prepolymers by using hydrogen-terminated polydimethylsiloxane, 1,2-epoxy-5-hexene, 1,2-epoxy-7-octene and 1,2-epoxy-9-decene as precursors.

Findings
The results revealed that the glass transition temperatures (Tg) and hydrophobicity increased with the chain length of open-chain epoxy monomer in the UV curable epoxy-based silicone coatings, and these films had excellent heat resistance, hydrophobicity, antigraffiti and ink removal properties.

Research limitations/implications
The cationic photocuring systems are not susceptible to the effect of oxygen inhibition. However, the limitation of cationic light curing process is that it requires a long curing time.

Originality/value
The coatings prepared via the UV curing approach can provide superior antismudge effects, and thus they are promising candidates for use in various industries, especially in fields such as antismudge coatings and antigraffiti coatings.
Quality of the accounting programmes of private universities in Ghana: alumni group perspectives
Authors: Bruce-Twum Ernest 
Published: May 2023

Purpose
Private universities in Ghana are perceived to offer low-quality education, even though the few studies conducted have produced contradictory findings. In addition to the paucity of research in this area, the debate has not largely reflected the views of alumni. This study aims to present the perspectives of a major stakeholder group in education on the quality of the accounting programme offered by a chartered private university in Ghana.

Design/methodology/approach
A survey questionnaire was sent to 150 alumni from a private university who graduated between 2011 and 2015 to gather data and analysed using descriptive statistical methods and hierarchical factor analysis.

Findings
In contrast to the perception of low-quality programmes in private universities in Ghana, the alumni group believed that the private institution offered good-quality accounting programmes. The accounting programme was accessed to be fit for its purpose, and it has generally transformed the lives of the alumni group, thus making the programme meet their quality expectations.

Practical implications
The study’s findings are an important contribution to the debate on the quality of private universities programmes in general and specifically in accounting.

Originality/value
Although some research has been done on quality assurances and accounting programmes in public universities in Ghana, the authors know very little about the quality in private universities. The study presents the opinions of an alumni group on the controversy over private universities quality of education. This study closes a gap in the literature.
