ABSTRACT The proliferation of massive open online courses (MOOCs) has sped up the evolution of online education. People now have a habit of checking internet reviews before deciding on and enrolling in an MOOC. However, issues about the veracity of online reviews have grown in significance. The S-O-R framework was used to determine the factors that have an impact on the reliability of reviews of MOOCs. The current study uses dual process theory (DPT) as a theoretical framework for identifying the stimuli. This finding reveals that review consistency and overall rating are more important in influencing the adoption of MOOC than the various informational factors. The findings also highlight that informal online communication (online reviews) is crucial to the adoption of e-learning.

Given the broad scope of Ethereum and the wide range of its decentralized applications, this paper investigates its hedging and safe haven capabilities against main fiat currencies, stock and bond indices in the US and Europe, and crude oil and gold markets. We use daily data from January 2016 until February 2021 and apply percentile regressions and crisis event interaction analysis by selecting four worldwide events including US presidential elections, the Brexit referendum, and COVID-19. We reveal that Ethereum does not act as a hedge or a safe haven against fiat currencies, stock and bond indices, and gold. However, it does act as a strong safe haven against crude oil in calm and turbulent periods and against European bonds during market turbulence. The study provides insights to regulators and investors into the potential role of Ethereum in investment decision-making and protecting financial market participants in the US and EU.
鉴于以太坊的广泛范围及其去中心化应用的广泛范围,本文研究了其针对主要法定货币、美国和欧洲的股票和债券指数以及原油和黄金市场的对冲和避险能力。我们使用2016年1月至2021年2月的每日数据,通过选择包括美国总统选举、英国脱欧公投和新冠肺炎在内的四个全球事件,应用百分比回归和危机事件互动分析。我们发现,以太坊并不是针对法定货币、股票和债券指数以及黄金的对冲或避风港。然而,在平静和动荡时期,它确实是抵御原油和市场动荡期间抵御欧洲债券的强大避风港。该研究为监管机构和投资者提供了关于以太坊在美国和欧盟投资决策和保护金融市场参与者方面的潜在作用的见解。

We are very pleased to present the collection of the papers of the 2022 Open Conference of the IFIP WG 8.3 Decision Support in this volume. The IFIP WG 8.3 conferences are organised bi-annually, and in 2022 we were able to organise the event again with a physical presence. The face-to-face talks were supplemented with online presentations, so we created a hybrid conference environment that could also be used for the future, which simultaneously ensured the possibility of personal discussions, debates, and social programmes, and online events for those who due to some reasons could not be present in person. This year, the conference was hosted by the Corvinus University of Budapest. At the University, research dealing with decision-making and decision support systems is carried out at various institutes and departments. The teaching and research activities of the Institute of Operations and Decision Sciences are diverse, they include trends and approaches discussing the preparation, support, understanding and shaping of decision-making, problem-solving processes – at individual, group, organisational, community and social level – encouraging participation, responsibility, and involvement. Our goal is to promote the development of decisionmaking practice primarily through the preparation of future decision-makers. This year’s conference entitled ‘Decision Support Systems: From Data Analytics to Intuition’ is set to highlight the trends in the increasing abundance of data, technological advancements, and the resulting requirement for a strong research focus on the decision-making continuum from human-centric decision-making approaches to analytics based decision-making approaches. Our focus is on how DSS expertise can support decision problems that arise across a diverse range of sectors including financial services, healthcare, manufacturing, hospitality, media, and many others. This supplemental issue includes the paper of Máté Farkas-Kis on Decision making in the shadow of mathematical education which received the Daniel J. Power Award for the best innovative DSS paper of the IFIP WG 8.3 Conference. We would like to express our warm thanks to the members of the Scientific Programme Committee.
我们非常高兴地在本卷中介绍2022年IFIP WG 8.3决策支持公开会议的论文集。IFIP WG 8.3会议每两年组织一次,在2022年,我们能够再次组织实际存在的活动。面对面的会谈辅以在线演示,因此我们创造了一个混合的会议环境,也可以用于未来,同时确保了个人讨论,辩论和社交节目的可能性,以及由于某些原因无法亲自出席的在线活动。今年的会议由布达佩斯科维努斯大学主办。在香港大学,有关决策和决策支持系统的研究在不同的研究所和学系进行。运营与决策科学研究所的教学和研究活动是多种多样的,它们包括趋势和方法,讨论准备,支持,理解和塑造决策,解决问题的过程-在个人,团体,组织,社区和社会层面-鼓励参与,责任和参与。我们的目标是主要通过培养未来的决策者来促进决策实践的发展。今年的会议题为“决策支持系统:从数据分析到直觉”,旨在强调数据日益丰富、技术进步的趋势,以及由此产生的对从以人为中心的决策方法到基于分析的决策方法的决策连续体的强烈研究需求。我们的重点是DSS专业知识如何支持各种行业出现的决策问题,包括金融服务、医疗保健、制造业、酒店、媒体和许多其他行业。本期增刊包括Máté Farkas-Kis关于数学教育阴影下的决策的论文,该论文获得了IFIP WG 8.3会议最佳创新DSS论文Daniel J. Power奖。我们要向科学计划委员会的成员表示热烈的感谢。

ABSTRACT Given Malaysia's stance on cryptocurrencies as a digitalisation pioneer, as well as the surge in crime and fraud, regulators and organisations are concerned about retail investors' intentions to invest in cryptocurrency. The research model integrates diffusion of innovation theory factors (compatibility, relative advantage, trialability, ease of use, and observability) with consumer behaviour theory focused on retail investors' perceptions (perceived risk and perceived value). A total of 304 responses were collected through purposive and respondent-driven sampling. The data was examined using SmartPLS Structural Equation Modelling (PLS-SEM). The findings show that compatibility, trialability, ease of use, observability, and perceived value have significant influences on the intention to invest in cryptocurrency. Meanwhile, the influence of relative advantage and perceived risk on the intention to invest in cryptocurrency is not supported. This research is vital for analysing the underlying motivations of Malaysian retail investors to invest in cryptocurrencies and further formulating the regulatory framework.

ABSTRACT Many Artificial Intelligence (AI) systems are black boxes, which hinders their deployment. Explainable AI (XAI) approaches which automatically generate counterfactual explanations aim to assist users in scrutinising AI decisions. One property of explanations crucial for their acceptance by users is their coherence. Users perceive counterfactual explanations as coherent if they present a realistic/typical counterfactual scenario that is suitable to explain the factual situation. We design an optimisation-based approach to generate coherent counterfactual explanations applicable to structured data. We demonstrate its applicability and rigorously evaluate its efficacy through functionally grounded and human-grounded evaluation. Results suggest that our approach indeed produces counterfactual explanations that are perceived as coherent by users. More specifically, they are perceived as more realistic, typical, and feasible than state-of-the-art explanations.

ABSTRACT This study aims to investigate the effect of social media features and national culture on online purchasing behaviour of luxury beauty products. The objective of this research is to explore the impacts of the social media’ dimensions (connectedness, openness, speed, accessibility, and participation) and national culture (measured through collectivism and uncertainty avoidance) on online purchasing behaviour. A research model was proposed and empirically tested through a quantitative methodology. A total of 280 responses were collected from Saudi women who are purchasers of luxury beauty products. The data were analysed through PLS-SEM method. The findings indicate that social media through their different dimensions is a crucial driver of online purchasing behaviour of luxury beauty products. However, national culture was found to have no influence on customer purchasing behaviour. The findings provide useful insights and appropriate online purchase behaviour guidelines for social commerce practitioners regarding luxury beauty products to increase visibility on the e-marketplace.
摘要本研究旨在调查社交媒体特征和民族文化对奢侈美容产品在线购买行为的影响。本研究的目的是探讨社交媒体的维度(连通性、开放性、速度、可访问性和参与性)和民族文化(通过集体主义和避免不确定性来衡量)对在线购买行为的影响。提出了一个研究模型,并通过定量方法进行了实证检验。共从购买奢侈美容产品的沙特女性那里收集了280份回复。用PLS-SEM方法对数据进行了分析。研究结果表明,社交媒体通过其不同的维度是奢侈品在线购买行为的关键驱动力。然而,民族文化对顾客的购买行为没有影响。这些发现为社交商务从业者提供了关于奢侈美容产品的有用见解和适当的在线购买行为指南,以提高电子市场的知名度。

This study explores the impact of the intensity of countries' digital transformation on the performance of 3961 global companies in the Information Technology sector in 2020. We analyse the impact of e-government index, e-participation index, and cybersecurity commitment on firms' performance (enterprise value, book value per share, and cash flow from operation per share) using OLS regression. A structural equation modelling was further employed to explain the mediating role of cybersecurity commitment. Results suggest that e-government has a positive linkage with cybersecurity commitment and performance. However, there is preliminary evidence that cybersecurity measures initiated by e-government will drive performance. The e-participation index has a positive association with cybersecurity commitment and a heterogeneous impact on performance, suggesting the need to differentiate between development and participation. Finally, results highlight the pivotal role of e-government and cybersecurity commitment in boosting the profitability of companies and supporting the influence of the surrounding technological environment on companies' performance.
本研究探讨了各国数字化转型的强度对2020年3961家全球信息技术公司业绩的影响。我们使用OLS回归分析了电子政务指数、电子参与指数和网络安全承诺对企业绩效(企业价值、每股账面价值和每股运营现金流)的影响。进一步采用结构方程模型来解释网络安全承诺的中介作用。结果表明,电子政务与网络安全承诺和绩效有着积极的联系。然而,有初步证据表明,电子政务启动的网络安全措施将推动绩效。电子参与指数与网络安全承诺呈正相关,并对绩效产生异质影响,这表明需要区分发展和参与。最后,研究结果强调了电子政务和网络安全承诺在提高公司盈利能力和支持周围技术环境对公司业绩的影响方面的关键作用。
