    • The impact of social media on consumer acculturation: current challenges, opportunities, and an agenda for research and practice

      Kizgin, Hatice; Dey, B.L.; Dwivedi, Y.K.; Hughes, L.; Jamal, A.; Jones, P.; Kronemann, B.; Laroche, M.; Peñaloza, L.; Richard, M-O.; et al. (2020-04)
      The concept of acculturation has been based on the assumption of an adaptation process, whereby immigrants lose aspects of their heritage cultures in favour of aspects of a host culture (i.e. assimilation). Past research has shown that acculturation preferences result in various possibilities and influence consumption behaviour. However, the impact of social media on consumer acculturation is underexplored, although the social purpose and information sharing online is utilized for a variety of social purposes. Recent studies have shown the transformation from an offline to an online context, in which social networks play an integral part in immigrants’ communications, relationships and connections. This study merges the views from a number of leading contributors to highlight significant opportunities and challenges for future consumer acculturation research influenced by social media. The research provides insights into the impact of social media on consumer acculturation.
    • Social media research in the context of emerging markets: an analysis of extant literature from information systems perspective

      Tamilmani, Kuttimani; Rana, Nripendra P.; Alryalat, M.A.A.; Al-Khowaiter, W.A.A.; Dwivedi, Y.K. (2018-05)
      Purpose: Despite the potential of social media in emerging markets (EMs), only few studies published in high quality information systems (IS) journals that have addressed issues related to social media in the context of EMs. This study aims to analyse existing research related to social media published in high quality IS journals for exploring initial research trends, emerging themes, limitations and future research directions in the context of emerging markets. Design/methodology/approach: This study conducted systematic review of 22 articles on social media, which were published in the “Senior Scholars Basket of IS Journals and Information Systems Frontiers” from 1997 to 2017. Manual literature search approach (i.e. screening through table of contents of each journal) was employed to identify relevant articles. The content of relevant articles was systematically analysed and synthesised along with keyword analysis to understand research trends on social media related issues in the emerging markets context. Findings: The study identified four major themes from existing research on the social media in the context of emerging markets, namely: 1) Social media frameworks; 2) Social media and consumers; 3) Social media and organisations; and 4) Social media and society with majority of the studies focusing on consumers. Single Subject was found as the major limitation with studies analysed focusing on single platform/country/domain hindering the generalizability whereas including new exogenous variable to improve the validity of existing studies emerged as main future research direction. Originality/value: This study conducted literature review on social media in EMs, which has not been undertaken yet. Moreover, it employed manual search (an effort and time intensive approach) to overcome the shortcomings of keyword search to identify, locate, select and analyse the social media literature in the context of emerging markets.
    • Examining adoption of mobile internet in Saudi Arabia: Extending TAM with perceived enjoyment, innovativeness and trust

      Alalwan, A.A.; Baabdullah, A.M.; Rana, Nripendra P.; Tamilmani, Kuttimani; Dwivedi, Y.K. (2018-11)
      Mobile internet represents a breakthrough technology that has derived much attention from mobile organizations and services providers in the Kingdom of Saudi Arabia (KSA).1 However, the level of acceptance of mobile internet in the KSA is still below the level of ambition. This is in addition to the fact that there is a considerable need to discover the main factors shaping Saudi customers' intention and adoption of such a mobile system. For this reason, this study is conducted in the hope of providing further understanding about the adoption of mobile internet in the KSA. The extension version of Technology Acceptance Model TAM2 with perceived enjoyment was adopted as a theoretical foundation of the current study model. This was expanded by considering two additional factors: innovativeness and trust. The main empirical data collected through questionnaires was analysed using structural equation modelling (SEM).3 Perceived usefulness, perceived enjoyment, trust, and innovativeness are statistically supported to have a significant impact on the Saudi customer intention to adopt mobile internet. Further discussion regarding the main contribution as well as research limitations and future directions are presented at the end of this paper.
    • Advances in social media research: past, present and future

      Kapoor, K.K.; Tamilmani, Kuttimani; Rana, Nripendra P.; Patil, P.; Dwivedi, Y.K.; Nerur, S. (2018-06)
      Social media comprises communication websites that facilitate relationship forming between users from diverse backgrounds, resulting in a rich social structure. User generated content encourages inquiry and decision-making. Given the relevance of social media to various stakeholders, it has received significant attention from researchers of various fields, including information systems. There exists no comprehensive review that integrates and synthesises the findings of literature on social media. This study discusses the findings of 132 papers (in selected IS journals) on social media and social networking published between 1997 and 2017. Most papers reviewed here examine the behavioural side of social media, investigate the aspect of reviews and recommendations, and study its integration for organizational purposes. Furthermore, many studies have investigated the viability of online communities/social media as a marketing medium, while others have explored various aspects of social media, including the risks associated with its use, the value that it creates, and the negative stigma attached to it within workplaces. The use of social media for information sharing during critical events as well as for seeking and/or rendering help has also been investigated in prior research. Other contexts include political and public administration, and the comparison between traditional and social media. Overall, our study identifies multiple emergent themes in the existing corpus, thereby furthering our understanding of advances in social media research. The integrated view of the extant literature that our study presents can help avoid duplication by future researchers, whilst offering fruitful lines of enquiry to help shape research for this emerging field.
    • Studying Transformational Government: A review of the existing methodological approaches and future outlook

      Omar, Amizan; Weerakkody, Vishanth J.P.; Daowd, A. (2020)
      In light of the heterogeneity of scholarly publications on the subject of transformational government (T-Gov), this paper examines research trends and assesses methodologies used to investigate the topic with the aim of analysing directions for future research. A comprehensive analysis of T-government research published in four Chartered Association of Business Schools ranked journals within the field of Public Administration, e-Government and Information System is presented. The paper outlines research directions for further inquiry to promote the formulation of much needed theoretical constructs and approaches to research that would help bridge the existing gaps in knowledge in the area of T-Gov.
    • Negative bubbles and shocks in cryptocurrency markets

      Fry, John; Cheah, E-T. (2016-10)
      In this paper we draw upon the close relationship between statistical physics and mathematical finance to develop a suite of models for financial bubbles and crashes. The derived models allow for a probabilistic and statistical formulation of econophysics models closely linked to mainstream financial models. Applications include monitoring the stability of financial systems and the subsequent policy implications. We emphasise the timeliness of our contribution with an application to the two largest cryptocurrency markets: Bitcoin and Ripple. Results shed new light on emerging debates over the nature of cryptocurrency markets and competition between rival digital currencies.
    • Quantifying the sustainability of Bitcoin and Blockchain

      Fry, John; Serbera, J-P. (2020)
      Purpose: We develop new quantitative methods to estimate the level of speculation and long-term sustainability of Bitcoin and Blockchain. Design/Methodology/Approach: We explore the practical application of speculative bubble models to cryptocurrencies. We then show how the approach can be extended to provide estimated brand values using data from Google Trends. Findings: We confirm previous findings of speculative bubbles in cryptocurrency markets. Relatedly, Google searches for cryptocurrencies seem to be primarily driven by recent price rises. Overall results are sufficient to question the long-term sustainability of Bitcoin with the suggestion that Ethereum, Bitcoin Cash and Ripple may all enjoy technical advantages relative to Bitcoin. Our results also demonstrate that Blockchain has a distinct value and identity beyond cryptocurrencies - providing foundational support for the second generation of academic work on Blockchain. However, a relatively low estimated long-term growth rate suggests that the benefi ts of Blockchain may take a long time to be fully realised. Originality/value: We contribute to an emerging academic literature on Blockchain and to a more established literature exploring the use of Google data within business analytics. Our original contribution is to quantify the business value of Blockchain and related technologies using Google Trends.
    • A Truly Future-Oriented Legal Framework for Fintech in the EU

      Kapsis, Ilias (2020)
      This article reviews critically the recent EU legislation and proposals for the regulation of financial technology (‘fintech”) and makes recommendations for legal improvements in the proposed frameworks, which will help to accelerate fintech growth, a declared EU goal, in the years to come. The rise of fintech driven by non-bank entities (technology startups, finance, big tech and big retail companies) helps to transform financial services industry, but also threatens the market positions of traditional banks and through them potentially the stability of the financial system. The current EU proposals, as presented in the Commission’s Fintech Action Plan published in 2018 and follow-up measures, outlined a number of steps to support fintech, while ensuring the protection of market stability and consumers and the maintenance of level playing field in the financial services markets. The article argues that, while the Commission’s proposed policy mix contains certain positive measures for fintech, it remains, overall, conservative and favours the incumbents. It also argues that unless the Commission becomes bolder and adopts a more flexible legal framework for fintech (for which the article makes specific recommendations), the latter will not grow at the pace needed to help build a competitive ad-vantage for the EU financial sector. The Commission’s continuing support of the established market landscape dominated by financial conglomerates employing traditional business models risks undermining the ability of the European financial system to adapt to the changing competition landscape created by advancing financial technologies and to fully address stability concerns, which emerged as a result of the financial crisis.
    • Entrepreneurs' Passion, Home Country's Institutional Voids and Small Firm Internationalization

      Adomako, Samuel; Amankwah-Amoah, J.; Chu, Irene (2020)
      The international entrepreneurship literature has revealed that entrepreneurs’ psychological characteristics drive a firm’s degree of internationalization. However, drivers that relate to entrepreneurs’ passion are not well developed in the international entrepreneurship literature. To fill this gap, this study uses a sample of 233 small firms to examine how entrepreneurs’ passion is related to small firms’ degree of internationalization and it also investigates whether this relationship is affected by levels of the home country’s institutional voids. The results show that passion is positively related to firms’ degree of internationalization and this relationship is positively moderated by levels of institutional voids. Implications for theory and practice are discussed.
    • Examining the impact of mobile interactivity on customer engagement in the context of mobile shopping

      Alalwan, A.A.; Algharabat, R.; Baabdullah, A.M.; Rana, Nripendra P.; Qasem, Z.; Dwivedi, Y.K. (2020)
      Purpose – This study aims to examine the impact of mobile interactivity dimensions (active control, personalization, ubiquitous connectivity, connectedness, responsiveness, and synchronicity) on customer engagement. Design/methodology/approach – A quantitative field survey study was conducted to collect the required data from actual users of mobile shopping in three countries: Jordan, the United Kingdom (UK) and Saudi Arabia. Findings – The results are based on structural equation modelling and support the impact of five dimensions of mobile interactivity: active control, personalization, ubiquitous connectivity, responsiveness, and synchronicity. Research limitations/implications – This study only considered the shopping activities conducted by mobile channels, while other channels (e.g. online channels, traditional channels, and social media shopping channels) are not considered. Furthermore, the current model does not consider the impact of personal factors (e.g. technology readiness, self-efficacy, user experience). The results of the current study present a foundation that can guide marketers and practitioners in the area of mobile shopping. Originality/value – This study enriches the current understanding of the impact of mobile interactivity on mobile shopping, as well as how mobile interactivity can enhance the level of customer engagement.
    • Measuring the efficiency of two stage network processes: a satisficing DEA approach

      Mehdizadeh, S.; Amirteimoori, A.; Vincent, Charles; Behzadi, M.H.; Kordrostami, S. (2020)
      Regular Network Data Envelopment Analysis (NDEA) models deal with evaluating the performance of a set of decision-making units (DMUs) with a two-stage construction in the context of a deterministic data set. In the real world, however, observations may display a stochastic behavior. To the best of our knowledge, despite the existing research done with different data types, studies on two-stage processes with stochastic data are still very limited. This paper proposes a two-stage network DEA model with stochastic data. The stochastic two-stage network DEA model is formulated based on the satisficing DEA models of chance-constrained programming and the leader-follower concepts. According to the probability distribution properties and under the assumption of the single random factor of the data, the probabilistic form of the model is transformed into its equivalent deterministic linear programming model. In addition, the relationship between the two stages as the leader and the follower, respectively, at different confidence levels and under different aspiration levels, is discussed. The proposed model is further applied to a real case concerning 16 commercial banks in China in order to confirm the applicability of the proposed approach at different confidence levels and under different aspiration levels.
    • Resilience strategies and the pharmaceutical supply chain: the role of agility in mitigating drug shortages

      Yaroson, Emilia V.; Breen, Liz; Hou, Jiachen; Sowter, Julie (2019)
      Supply chain resilience has been suggested to curb the impact of disruptions on supply chains. While this proposition seems coherent in theory, empirical evidence supporting this is limited, as existing literature has centred on exploring the impact of supply chain resilience on disruptions which are based on set time frames, non-supply chain specific as well as examining non-dynamic disruptive events. This study contends that resilience strategies are dynamic and as such their applications within supply chains differ. Therefore examining the impact of resilience will be appropriate on a dynamic disruption within a specific supply chain. In view of this, the paper examines through existing literature the applicability of agility within the pharmaceutical supply chain when dynamic disruptions like drug shortages occur. The study finds alertness, accessibility, connectivity and visibility as dimensions of supply chain agility that are capable of reducing the impact of drug shortages.
    • The others: the role of individual personality, cultural acculturation, and perceived value on towards firm's social media and acculturation orientation

      Foroudi, P.; Marvi, R.; Kizgin, Hatice (Elsevier, 2020)
      This paper systematically examines (i) how individual personality can influence on cultural acculturation which can impact on the higher level of perceived value in LGBTs, and (ii) how the higher level of perceived value towards social media can result in being more satisfied, (iii) consequently having a better working life at workplace and performance proficiency. The generated framework was validated through a survey from multinational corporations in multi-industries such as higher education (with more than two campuses around the world), global fashion, global retailing, tourism, hospitality, food, and electronics and information technology. Key results, implications for managers and researchers are highlighted.
    • FPIC right of indigenous people and local communities in resource development: lessons from the Inter-American jurisprudence

      Songi, O.; Enenifa, J.A.; Chinda, J.K.; Olokotor, Prince N.C.; Topman, V. (Uniport Journal of Private Law, 2017)
    • Judicial attitudes towards the enforcement of annulled awards

      Matipe, J.A.P.; Olokotor, Prince N.C. (Kluwer Law International, 2018-06)
      This chapter explores the issue of the enforcement of annulled awards under the regime of the Convention on the Recognition and Enforcement of Foreign Arbitral Awards, New York 1958 (New York Convention) through an analysis of recent decisions from the courts of the United States, England and France, to suggest the attitude courts in African States should adopt when required to enforce an annulled award. These three jurisdictions have robustly engaged with this question and their courts have proffered different reasons for the positions they take on the issue, which may be instructive to the courts in Africa. The issue is set out in 14.01; and the theoretical and practical effects of annulled awards are briefly discussed in 14.02. The approach adopted by the English courts is briefly examined in 14.03; the US courts in 14.04; and the French courts in 14.05; and a conclusion.
    • Examining the relationship between social media analytics practices and business performance in the Indian retail and IT industries: The mediation role of customer engagement

      Garg, P.; Gupta, B.; Dzever, S.; Sivarajah, Uthayasankar; Kumar, V. (2020)
      Social media analytics (SMA) is a dynamic field which has received considerable attention from both academics and management practitioners alike. A significant number of the scholarly research currently being conducted in SMA, however, is conceptual. Industry experts know that SMA creates new opportunities for organisations who want to more strongly engage with their customers and improve business performance. However, the relationship between social media analytic practices (SMAP), customer engagement (CE), and business performance (BP) has not yet been sufficiently investigated from an empirical perspective. In order to gain a better understanding of the relationship between SMAP and BP and the mediation role of CE in that process, a large-scale survey was conducted among senior and mid-level managers as well as consultants in the Retail and information technology (IT) industries in India. Specifically, a structured closed-ended questionnaire was administered to managers and management consultants country-wide and gathered usable responses from 281 respondents holding positions such as: Digital Marketing Executive/Digital Marketing Specialist, Management Consultant, Analytics Manager, Customer Relationship Manager, Marketing Director, Engagement Manager, etc. who were in charge of digital marketing strategies in the respondent retail and IT organisations. The questionnaire addressed issues related to the way in which SMAP contribute to an enhanced business performance through the mediation role of customer engagement. Structural Equation Modelling was employed to analyse the received empirical data. On the basis of the findings our research concludes that there is a significant positive relationship between SMAP and BP mediated by CE in the Indian retail and IT industries.

    • Intelligent and energy efficient mobile smartphone gateway for healthcare smart devices based on 5G

      Sigwele, Tshiamo; Hu, Yim Fun; Ali, Muhammad; Hou, Jiachen; Susanto, M.; Fitriawan, H. (2018-12)
      The healthcare sector is now blending with Information and Communications Technology (ICT) using Internet of Things (IoT) to potentially minimise medical errors and reduce healthcare cost. Patients are now embedded with smart devices like body sensors and wearable devices which can monitor their health without the need for a doctor in physical contact. Such smart devices have the downside of low battery power and are unable to transmit their data to the medical personnel when the patient is on the move away from the smart home/smart clinic fixed gateway. A mobile gateway is required which moves with the patient to process the smart device data without depleting the smartphone battery. This paper proposes an Intelligent and Energy Efficient SG based smartphone Gateway for healthcare smart devices (IEE5GG). In IEE5GG, the 5G architecture is adopted and the patient's smartphone is used as a gateway where multiple smart devices are connected e.g. via Bluetooth. To save energy, requests to the smartphone can either be executed on the smartphone gateway or offloaded and executed in the Mobile Edge Computing (MEC) cloud at close proximity to the smartphone in the 5G Base Station (BS) central Unit (gNB-CU) while considering the transmission power, Quality of Service (QoS), smartphone battery level and Central Processing Unit (CPU) load. Results show that the proposed IEE5GG framework saves up to 38% of energy in the healthcare mobile gateway smartphone and reduces healthcare application service time by up to 41%.
    • The battle of Brain vs. Heart: A literature review and meta-analysis of "hedonic motivation" use in UTAUT2

      Tamilmani, Kuttimani; Rana, Nripendra P.; Prakasam, N.; Dwivedi, Y.K. (2019-06)
      Much of the scholarly debate on the extrinsic-intrinsic motivation dichotomy to date has focused on organisational context. However, the recent upsurge of technology use amongst individuals in non-organisational context has led to consumer-focused research model such as extended unified theory of acceptance and use of technology (UTAUT2). The objective of this study is to bring back much needed focus on motivation dichotomy from the consumer perspective. This involved a systematic review and meta-analysis of hedonic motivation an affective construct in UTAUT2 studies. The findings from 79 UTAUT2 empirical studies revealed that only 46 studies (58%) utilised hedonic motivation while the remaining 33 studies (42%) omitted the construct. Extrinsic motivation was the major driver of non-hedonic and non-significant hedonic motivation studies with individuals using technologies for utilitarian outcomes. Unlike UTAUT2, moderators association of hedonic motivation were non-significant in determining consumer intention to use technology. The findings also revealed an important association between hedonic motivation and effort expectancy, in addition to fruitful directions for research and practice.
    • Elementary modelling and behavioural analysis for emergency evacuations using social media

      Fry, John; Binner, J.M. (2016-03)
      Social media usage in evacuations and emergency management represents a rapidly expanding field of study. Our paper thus provides quantitative insight into a serious practical problem. Within this context a behavioural approach is key. We discuss when facilitators should consider model-based interventions amid further implications for disaster communication and emergency management. We model the behaviour of individual people by deriving optimal contrarian strategies. We formulate a Bayesian algorithm which enables the optimal evacuation to be conducted sequentially under worsening conditions.
