In the digital environment, chatbots as customer service agents assist consumers in decision making. Based on the computers-are-social-actors paradigm, this study examines the perceived differences in communication quality and privacy risks between different service agents and their impact on consumers' adoption intention, and investigates whether...
Text-based chatbots are being touted as a disruptive innovation with unprecedented business potential. However, frequent failures in human–chatbot conversations have led to consumer pushback. This study investigates the response of consumers to chatbots in terms of their intention to switch to human agents. Drawing upon the stimulus–organism–respon...
Information security is one of the important domains of information systems research today, with protection motivation theory (PMT) one of its most influential theoretical lenses. However, empirical findings based on PMT are often inconsistent and inconclusive. To reconcile these inconsistent findings, we conducted a meta-analysis to investigate th...
Cross-border electronic-commerce (CBEC) is growing. However, due to differences in culture, habits, history and language among other factors, consumers in different regions may have different perception towards the same product information on CBEC platforms, which may lead to differences in their cognition of the product with implications for purch...
As cross-border e-commerce becomes more popular among global consumers and more important to global trade, there is a growing need for e-commerce research that explores the factors contributing to the success of global electronic markets. Yet, most extant literature on cross-border e-commerce is carried out from a buyer’s perspective. In this study...
Cross-border m-commerce (CBMC) has significant potential but few online firms are involved in CBMC markets due to low acceptance among both buyers and sellers. In addition, customers who engage in CBMC may switch between several different e-marketplaces. This study focuses on understanding consumer intentions toward CBMC usage. We proposed an integ...
Purpose
The purpose of this paper is to develop and test a model of the uncertainties and benefits influencing the repurchase intentions of buyers in cross-border e-commerce (CBEC).

The authors draw on the valence framework to hypothesize effects of positive valences (utilitarian benefits) along with negative valences (...
While past studies have considered the educational benefits of industry tools and simulated games within BPM courses, the relative efficacy of these interventions for student outcomes has not yet been established. In this study we sought to determine whether added exposure to industry tools would be more, or less, effective at influencing students’...
User satisfaction (US) is an important information systems success measure. This paper contributes to our understanding of US in workplace settings by conceptualizing US as resulting from user evaluations of both the attribute level performance of the system and its impacts on the motivating potential of their work. Data was collected from a sample...
Access to digitally connected living should support social and economic inclusion and provide opportunities for people to improve their quality of life. Yet evidence linking digital access and quality of life is lacking. We contribute by examining the relationship between quality of life and the extent to which individuals have accessed the Interne...
Consumers’ risk perception and trust are considered among the most important psychological states that influence online behavior. Despite the number of empirical studies that have explored the effects of trust and risk perceptions on consumer acceptance of e-services, the field remains fragmented and the posited research models are contradictory. T...
Young people are important to cities, bringing skills and energy and contributing to economic activity. New technologies have led to the idea of a smart city as a framework for city management. Smart cities are developed from the top-down through government programmes, but also from the bottom-up by residents as technologies facilitate participatio...
Purpose
The purpose of this paper is to help understand consumer acceptance of online health information services by integrating the health belief model and extended valence framework.
Design/methodology/approach
A laboratory-based, experimental-scenarios research design is used to collect data, and the structural equation modeling technique is us...
The popularity of online health information has increased because of its easy accessibility. The present study employs a longitudinal data to investigate perceived ease of use, perceived usefulness, and trust in the online health information context. More specifically, we classified trust as both trust in the provider and in the website for health...
The current study seeks to contribute to the literature on the use of digital game based learning (DGBL) in Information Systems (IS) education by providing empirical evidence concerning the effect of the inclusion of DGBL on students’ motivation and perceived competence within the context of a business process management (BPM) course. A pre-test/po...
E-services remain characterised by uncertainty despite their proliferation. Consumer trust beliefs are therefore considered an important determinant of e-service adoption. However, the research has not yet considered the potentially dynamic nature of these trust beliefs or how early-stage trust might influence later-stage adoption and use. To addre...
We examine consumers’ early stage trust beliefs for effects on perceptions of information and system quality, later stage trust, satisfaction and usage intentions in the context of online health services. Using a longitudinal research design, data was collected from a sample of undergraduates during two time periods, approximately five weeks apart....
Purpose:
Health workers have numerous concerns about hospital IS (HIS) usage. Addressing these concerns requires understanding the system attributes most important to their satisfaction and productivity. Following a recent HIS implementation, our objective was to identify priorities for managerial intervention based on user evaluations of the perf...
User satisfaction (US) is an important information systems success measure. This paper contributes to our understanding of US in workplace settings by conceptualizing US as resulting from user evaluations of both the attribute level performance of the system and its impacts on the motivating potential of their work.

This paper reports on a systematic review of the evidence into the use and impacts of e-health in community-based healthcare facilities within developing countries. Thirteen studies met our inclusion criteria. Use was influenced by infrastructural challenges, user experience, system performance problems and lack of perceived usefulness. The majorit...
While there is established research that explores individual innovations across countries or developments in a specific health area, there is less work that attempts to match national innovations to specific systems of health governance to uncover themes across nations.
We used a cross-comparison design that employed content analysis of health gove...
Competing theoretical perspectives regarding the effects of knowledge management (KM) on performance have underpinned past empirical studies. By explicitly surfacing and comparing three such perspectives, we contribute to the theoretical advancement of the KM field. We develop hypotheses consistent with the underlying logics of universalistic, comp...
Equipping Community Health Workers (CHWs) in resource-constrained settings with mobile-health or
‘mHealth’ tools has the potential to improve healthcare service delivery. mHealth tool functionality must
however match CHW task needs before these tools are likely to have any significant impacts on CHW
performance. This paper contributes by drawing on...
Cloud computing offers a number of advantages for organisations looking to rent on-demand IT resources as a service. However, there are also uncertainties and challenges to cloud computing use that are tempering the rate of adoption. This paper contributes to our understanding of cloud computing adoption within South African firms by developing and...
Community Health Workers (CHWs) are often the only link to healthcare for millions of people in the developing world. There is growing interest in supporting CHWs at the point-of-care through the application of mobile-health or mHealth platforms. Despite the promise of these technologies, there is a lack of substantive evidence regarding the impact...
This study set out to answer the question: what would a gesture set for conducting an informational search on a multi-touch tablet web browser look like if designed in collaboration with users with limited touch screen experience? In addressing this question, we developed such a user-defined gesture set, based on gestures elicited from participants...
Consumers' trust beliefs are considered amongst the most important psychological states influencing their online behaviour. Understanding the antecedents of consumer trust is thus of both academic and practical interest. Research into these antecedents has however been disconnected, and has not been integrated to provide an answer as to which are t...
The Web is an important health information dissemination channel. Potential benefits cannot materialize unless online health information services are accepted and used by consumers. This study develops a research model by integrating the health belief model (HBM) and extended valence framework to explain user acceptance (behavioral intentions). We...
Despite the proliferation of e-services, they are still characterized by uncertainties. As result, consumer trust beliefs are considered an important determinant of e-service adoption. Past work has not however considered the potentially dynamic nature of these trust beliefs, and how early-stage trust might influence later-stage adoption and use. T...
The concept of a "Smart City" has been approached from different perspectives by researchers from different field in recent years. In the process, various characteristics of "smartness" have been proposed and explored. while there are elements in common, the different ways of understanding the term "Smart City" revel different assumptions about cit...
The potential of information technology (IT) resources to empower employees, to shape customer service and contribute to the competitive performance of hospitality firms has received much attention. Yet empirical evidence has been lacking. This study draws on the resource-based view of the firm and the service-profit chain framework to develop and...
E-prescribing systems hold promise for improving the quality and efficiency of the scripting process. Yet, the use of the technology has been associated with a number of challenges. The diffusion of e-prescribing into physician practices and the consequent realisation of its potential benefits will depend on whether physicians are willing to accept...
Consumer perceptions of risk and their trust beliefs are considered amongst the most important psychological states influencing online behavior. Despite the number of empirical studies that have explored the effects of trust and risk perceptions on consumer acceptance of e-services, the field remains fragmented and the posited research models are c...
There is increasing interest in reaching and empowering patients and health consumers directly through information technology (IT). However, consumer readiness for an increasingly IT-enabled healthcare system has been questioned and there remains a need for more theory driven research into IT adoption by health consumers. This study has contributed...

The role and contribution of the firm’s Chief Information Officer has been the subject of much debate and uncertainty. Yet, too few empirical studies have examined the implications of the CIO role. This study examined the effects of CIO demography, CIO competencies as well as CIO orga...
This teaching case presents a systems development project useful for courses in object-oriented analysis and design. The case has a strong focus on the business, methodology, modeling and implementation aspects of systems development. The case is centered on a fictitious ambulance and emergency services company (Rescue911). The case describes that...
While studies have shown the effect of context on IS planning as important, the incorporation of contextual factors has not been systematic and the categorization of factors has not been made explicit and some factors have only been superficially examined. My study examined the interrelationships amongst four domains of context and considered their...
The high rate of systems development (SD) failure is often attributed to the complexity of traditional SD methodologies (e.g. Waterfall) and their inability to cope with changes brought about by today's dynamic and evolving business environment. Agile methodologies (AM) have emerged to challenge traditional SD and overcome their limitations. Yet em...
Lack of a close ‘Information systems (IS)–business relationship’ has been described as a potential inhibitor to improving the contribution that information systems (IS) make to business performance. Yet the value of specific attributes of an enduring relationship between IS and business remains to be demonstrated by empirically confirming their lin...
Contingeney theory suggests that various environmental, organizational and managerial factors will influence an organization's approach to IT management. This chapter discusses the contingent nature of information systems strategic planning (ISSP) practices and presents the results of an empirical study of ISSP and the role of IS within 90 leading...

The strategic management literature has been attempting to confirm the validity of strategic planning as a managerial activity for the past 30 years. Results, however, have been confusing and contradictory and have done little to advance the cause of strategic planning as a rational approach to strategy formulation. In order to better understand th...
Projects
Project (1)
Our research has an overarching goal to better understand how information systems contribute (or could contribute) to the development of Smart Cities in the African context.
Specifically the project has investigated the following research questions:
1) What are the information needs and preferences of individuals resident in and organisations operating in Johannesburg (and, possibly, other African cities), as well as the information needs and preferences of visitors to Johannesburg (and, possibly, other African cities)?
2) How can the information needs and preferences identified be mapped to information based services that are or could be provided? What processes are and/or could be used to make such mappings and how do these compare with existing processes for how such mappings can be made? What theoretical models might best inform such processes?
3) What information services are provided within Johannesburg (and, possibly, other African cities), in what forms and by whom? Who uses such services and (where feasible) what is their impact?
4) What are the gaps in service provision? How can the information based services identified be mapped to technology devices and applications, and providers of services? What processes are and/or could be used to make such mappings and how do these compare with existing processes for how such mappings can be made? What theoretical models might best inform such processes?
