Mobile business travel application usage : are South African men really from Mars and women from Venus?

PURPOSE : Research abounds highlighting the differences between males and females when they travel. Even in business travel, these differences have been acknowledged, with suppliers and marketers spending significant money to develop and market products to accommodate them. The purpose of this study is to ascertain whether differences exist in terms of mobile application usage between male and female business travellers. DESIGN/METHODOLOGY/APPROACH : A mixed method approach is followed. An internet-based survey is distributed and in-depth interviews conducted with South African business travellers. The Mann–Whitney U-test is used to test the differences between males and females and their mobile application usage. Content analysis is used to analyse the interviews. FINDINGS : The results show that mobile applications are perceived as more important by females than males in all the phases of the travel cycle, although most of these differences in perceived importance were not significant. RESEARCH LIMITATIONS/IMPLICATIONS : Owing to the online data-collection method and the self-selective process, the findings cannot be generalised to the global population of business travellers who use mobile applications. PRACTICAL IMPLICATIONS : The results should caution corporate organisations, travel management companies and their application developers not to spend unnecessary technological and financial resources on developing applications to accommodate differences between males and females, which might not exist. Companies should rather spend money on developing applications that will enhance and add convenience to the business traveller’s experience. ORIGINALITY/VALUE : The main contribution of this study lies in investigating the applications market, particularly in the context of business travel. Applications focussed on specific sectors of the tourism industry, such as business travel applications, serve business travellers differently from generic travel applications. This research examines business travel-specific applications and expands the scale and scope of the enquiry, concentrating on the travellers’ view.https://www.emerald.com/insight/publication/issn/1757-9880hj2020Tourism Managemen

No woman's land:Feminist approaches to the ride-hailing sector and digital labor platforms in India

In this dissertation, I investigate the concerns, issues and opportunities for platform labor reform with a focus on the ride-hailing sector using Bardzell (2010)’s feminist lens. The feminist viewpoint keeps the marginal user at the center committing to equity, diversity, identity, empowerment, and social justice to improve the work conditions of gig workers in the Global South. By conducting in-depth qualitative interviews with the different stakeholders of the ride-hailing sector, and analysing case studies, media coverage, policy papers, and research reports, I suggest guidelines for redesigning the digital labor platforms

Sustainable interaction with digital technologies : fostering pro-environmental behavior and maintaining mental health

One of the most essential challenges of the twenty-first century is to realize sustainability in everyday behavior. Daily, partly unconscious decisions influence environmental sustainability. Such everyday choices are increasingly shifted toward digital environments, as digital technologies are ubiquitous in a wide variety of everyday contexts. This yields the great potential to positively influence the users behavior toward more environmental sustainability when interacting with digital technologies, for example, through the use of digital nudging. But besides these benefits, research indicates that interacting with digital technologies can lead to a specific form of stress, also known as technostress, that can cause adverse health outcomes. Individuals increasingly suffer from or are at risk of mental health issues like depression or burnout. This demonstrates that it is essential to ensure a sustainable interaction with digital technologies that is both environmentally friendly and healthy, especially for the mind. Addressing individuals interaction with digital technologies requires a broad understanding from all perspectives. The Human-Computer-Interaction (HCI) framework represents a guiding structure for studying the interaction of humans with digital technologies. Along with the guiding structure of the HCI framework, the seven research articles included in this dissertation aim to contribute to sustainable interaction with digital technologies. The focus is on two outcomes resulting from the interaction: First, fostering pro-environmental behavior and, second, maintaining mental health. After an introductory first chapter, Chapter 2 focuses on the outcome of fostering pro-environmental behavior when interacting with digital technologies using digital nudging. Chapter 2.1 contributes to a deeper understanding of the effectiveness of DNEs in different behavioral contexts (HCI perspective context) that influence the individuals pro-environmental behavior (e.g., e-commerce shopping behavior). Chapters 2.2 and 2.3 zoom in on two of the behavioral contexts described in Chapter 2.1 to investigate and test the design and effectiveness of specific DNEs in an e-commerce shop and a smart home app (HCI perspective technology) through online experiments. While prior research concentrated on the effectiveness of different feedback nudge features (FNFs) (e.g., different update frequencies), Chapter 2.4 investigates the influence of 25 identified FNFs on user satisfaction in a smart home app through a card sorting approach followed by an online survey based on the Kano model (HCI perspective human). Chapter 3 puts focuses on the outcome of maintaining mental health when interacting with digital technologies, thus avoiding technostress. Chapter 3.1 concentrates on the role of the organization in preventing technostress among their employees (HCI perspective context). It introduces and characterizes 24 primary and secondary technostress prevention measures and determines the relevance of primary prevention measures in reducing different sources of technostress (technostress creators). Out of the 24 technostress prevention measures, two specific measures (adopt a stress-sensitive digital workplace design and use gamification) are addressed in Chapters 3.2 and 3.3. Through a large-scale online survey, Chapter 3.2 derives an understanding of the characteristic profiles of technologies used at the digital workplace, their interplay, and how they influence technostress (HCI perspective technology). Chapter 3.3 focuses on the individuals appraisal (HCI perspective human) of a demanding situation when interacting with digital technologies. After conducting an online experiment, Chapter 3.3 finds that the integration of gamification elements (e.g., points or levels) in digital technologies can reduce the individuals threat appraisal. Lastly, Chapter 4 discusses the results of the seven included research articles and provides an outlook for future research. In summary, this dissertation aims to provide research and practice with new insights into creating a sustainable interaction with digital technologies to foster pro-environmental behavior and maintain mental health.Die nachhaltige Gestaltung des Lebens eine der zentralen Herausforderung des einundzwanzigsten Jahrhunderts. Alltägliche, teils unterbewusste Entscheidungen haben Einfluss auf die ökologische Nachhaltigkeit. Diese Entscheidungen werden durch die Allgegenwärtigkeit digitaler Technologien zunehmend in digitalen Umgebungen getroffen. Dies birgt das Potenzial, die Entscheidungen und somit das Verhalten der Nutzer:innen bei der Interaktion mit digitalen Technologien, beispielsweise durch Digital Nudging, positiv in Richtung ökologischer Nachhaltigkeit zu beeinflussen. Doch neben diesen Vorteilen zeigt die Forschung, dass die Interaktion mit digitalen Technologien eine spezifische Form von Stress, bekannt unter dem Begriff Technostress, auslösen kann, die zu negativen gesundheitlichen Folgen führen kann. Immer mehr Menschen leiden unter psychischen Krankheiten wie Depressionen oder Burnout oder sind akut gefährdet, diese zu entwickeln. Das zeigt, dass eine nachhaltige Interaktion mit digitalen Technologien sowohl umweltfreundlich als auch gesund, insbesondere für die Psyche, sein sollte. Das erfordert zunächst ein umfassendes Verständnis für die Problematik und muss deshalb aus allen relevanten Perspektiven betrachtet werden. Das Human-Computer-Interaction (HCI) Framework stellt eine Struktur für die Untersuchung der Interaktion von Menschen mit digitalen Technologien bereit. Das Framework stellt einen ganzheitlichen Ansatz zur Strukturierung und Klassifizierung der Forschung entlang der drei verschiedenen Perspektiven dar. Orientiert an dieser Struktur zielen die sieben Forschungsartikel dieser Dissertation darauf ab, einen Beitrag zur nachhaltigen Interaktion mit digitalen Technologien zu leisten. Dabei liegt der Fokus auf den beiden Ergebnissen der Förderung des umweltfreundlichen Verhaltens und der Aufrechterhaltung der psychischen Gesundheit. Nach dem einleitenden ersten Kapitel fokussiert Kapitel 2 die Förderung eines umweltfreundlichen Verhaltens bei der Interaktion mit digitalen Technologien durch die Verwendung von Digital Nudging. Durch eine strukturierte Literaturanalyse und der anschließenden Entwicklung eines Frameworks trägt Kapitel 2.1 zu einem tieferen Verständnis und einem Überblick der Effektivität von DNEs in verschiedenen Verhaltenskontexten (HCI Perspektive Kontext), die umweltfreundliches Verhalten bestimmen (z.B. Einkaufsverhalten), bei. In den Kapiteln 2.2 und 2.3 werden zwei der in Kapitel 2.1 betrachteten Kontexte vertieft und sowohl das Design als auch die Effektivität spezifischer DNEs in einem E-Commerce-Shop (Kapitel 2.2) und einer Smart Home App (Kapitel 2.3) in Online-Experimenten untersucht (HCI Perspektive Technologie). Kapitel 2.4 konzentriert sich das gut erforschte und wirksame DNE Feedback zur Förderung von energiesparendem Verhalten. Während sich bisherige Forschung auf die Effektivität verschiedener Feedback Nudge Features (FNFs) konzentriert (z.B. unterschiedliche Aktualisierungsfrequenzen), wird in Kapitel 2.4 der Einfluss von 25 identifizierten FNFs auf die Nutzerzufriedenheit mit Hilfe eines Card Sortings und einer Online-Befragung basierend auf dem Kano Modell untersucht (HCI Perspektive Mensch). In Kapitel 3 liegt der Schwerpunkt auf dem Ziel der Aufrechterhaltung der psychischen Gesundheit und somit der Vermeidung von Technostress. Kapitel 3.1 konzentriert sich auf die Rolle der Organisation bei der Prävention von Technostress bei Mitarbeiter:innen (HCI Perspektive Kontext). Basierend auf einer Delphi-Studie werden 24 primäre und sekundäre Technostress-Präventionsmaßnahmen vorgestellt und charakterisiert, sowie deren Relevanz zur Vermeidung von Technostress eingeschätzt. Von den 24 Maßnahmen werden zwei spezifische Maßnahmen (Gestaltung eines stresssensiblen digitalen Arbeitsplatzes" und Einsatz von Gamification) in Kapitel 3.2 und 3.3 behandelt. Kapitel 3.2 trägt durch eine groß angelegte Umfrage zu einem Verständnis für die Charakteristika der am digitalen Arbeitsplatz eingesetzten Technologien und deren Einfluss auf Technostress bei (HCI Perspektive Technologie). Kapitel 3.3 konzentriert sich auf das Individuum und dessen Wahrnehmung einer potenziellen Technostress-Situation bei der Interaktion mit digitalen Technologien (HCI Perspektive Mensch). Durch ein Online-Experiment zeigt sich, dass die Integration von Gamification-Elementen in digitalen Technologien die bedrohende Wahrnehmung der gegebenen Situation des Einzelnen reduzieren kann. Zusammenfassend zielt diese Dissertation darauf ab, Forschung und Praxis mit neuen Erkenntnissen zu einer nachhaltigen Interaktion von Menschen mit digitalen Technologien zu bereichern, die sowohl umweltfreundliches Verhalten fördert als auch die psychische Gesundheit aufrechterhält und somit zu den aktuellen Nachhaltigkeitsbemühungen beiträgt

Resilient design for London's elevated social spaces: exploring challenges, opportunities, and harnessing interactive virtual reality co-design approaches for community engagement

In the face of escalating urban density, the emerging concept of elevated urban spaces such as sky gardens and roof gardens is becoming a compelling requirement for human well-being in the process of densification. These spaces have gained additional significance in light of the adaptability and resilience required during the Covid-19 pandemic. This research explores the challenges and opportunities related to the design and management of such spaces, with a specific focus on London. A novel facet of this investigation is the application of Virtual Reality (VR) technology as a co-design tool, aimed at enhancing public engagement and the overall design experience of these spaces. The study emphasizes two particular urban locales in London: the Sky Garden and Crossrail Place, chosen for their unique design characteristics, public accessibility, and popularity. These case studies allow for an in-depth examination of critical design aspects such as accessibility, people flow control, pinch points, user experience, and the spectrum of activities that these spaces can accommodate. To create more sustainable and inclusive environments, the study leverages VR technology to bridge the gap between the physical and virtual worlds. This approach is aimed at understanding the impact of this integration on architectural and urban design processes, specifically in terms of design decision-making and its implications for the sustainability and longevity of public places. The adopted methodology is a phenomenological qualitative approach employing the Participatory Action Research (PAR) method. This involved direct observational studies, walk-along interviews with 33 visitors at each site, VR exploratory experiments with the same number of participants, and follow-up semi-structured interviews. Observations were conducted before, during, and after the Covid-19 pandemic, providing a comprehensive perspective on the unique challenges influencing the design and management of elevated urban spaces. The results indicate that VR, as a co-design tool, effectively promotes interactive public participation in the design process. The VR experiments facilitated users to identify design limitations and suggest improvements, even among participants who had not physically visited the sites. The concerns and needs identified through VR closely mirrored those expressed by actual users of the spaces. The findings also offer a comparative analysis of human activities, circulation patterns, and design considerations in both physical and virtual environments, highlighting the potential of VR technology for designing sustainable public spaces in a post-pandemic world. This research contributes threefold: (a) it furnishes theoretical input by establishing guidelines for the design of elevated social spaces, and provides empirical input by suggesting a range of design and planning considerations for developing active, pleasant, and resilient elevated social spaces; (b) it offers methodological input through the development of a multidisciplinary pragmatic framework for assessing the use of VR as an interactive co-design tool; and (c) it presents a comparative analysis of two advanced interactive VR approaches – Building Information Modeling (BIM) and gamification techniques – to enhance public engagement in public and social space design

Aiding information security decisions with human factors using quantitative and qualitative techniques

Phd ThesisThe Information Security Decision Making Process is comprised of an extremely complex and dynamic set of sub-tasks, sub-goals and inter-disciplinary practices. In order to be effective and appropriate, this process must balance both the requirements of the stakeholder as well as the users within the system. Without careful consideration of users’ behaviours and preferences, interventions are often seen as obstacles towards productivity and subsequently circumvented or simply not adhered to. The approach detailed herein requires an intimate knowledge of both Information Security and Human Behaviour. An effective security policy must adequately protect a given set of assets (human and non-human) or systems as well as preserve maximal productivity. Companies rely on their Intellectual Property Rights which are often stored in a digital format. This presents a plethora of issues regarding security, access management and locality (whether on or off the premises). Furthermore, there is the added complexity of employees and how they operate within this environment (a subset of compliance, competence and policy). With the continued increase in consumerisation, more specifically the rise of Bring Your Own Device, there is a significant threat towards data security that persists outside of the typical working environment. This trend enables employees to access and transfer corporate assets remotely but in doing so creates a conflict over identity, ownership and data management. The governance of these activities creates an extremely complex problem space which requires the need to balance these requirements relying on an accurate assessment of risk, identification of security vulnerabilities and knowledge pertaining to the behaviour of employees. The risks to company assets can be estimated by the analysis of the following issues: • Threats to your assets. These are unwanted events that could cause the deliberate or accidental loss, damage or misuse of the assets. • Vulnerabilities. How susceptible your assets are to attack. • Impact. The magnitude of the potential loss or the seriousness of the event. The ability to quantify and accurately represent these variables is critical in developing, implementing and supporting a successful security policy. The dissertation is structured as follows. Chapter 1 provides an abstract overview of the problem space and highlights our aims, objectives and publications. Chapter 2 details an in-depth literature review of the cross-disciplinary problem space. This involves both the analysis of industry standards, practices and reports as well as a summary of academic literature pertaining to theoretical frameworks and simulations for discussion. Chapter 3 introduces our problem space and documents the rationale for designing our methodology. Each successive chapter (4, 5, & 6) documents a separate investigative strategy for populating specific data sets with respect to the behaviours and practices highlighted from our pilot study and CISO interaction. This provides the rationale behind each approach as well as a documented implementation and evaluation of our experimental design with reference to publications in the field. Chapter 7 documents our modelling strategy and highlights the extensions we propose to the BPMN 2.0 formalism. Chapter 8 concludes our work with reference to our contributions, limitations and the direction of future study

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Human Computer Interaction and Emerging Technologies

The INTERACT Conferences are an important platform for researchers and practitioners in the field of human-computer interaction (HCI) to showcase their work. They are organised biennially by the International Federation for Information Processing (IFIP) Technical Committee on Human–Computer Interaction (IFIP TC13), an international committee of 30 member national societies and nine Working Groups. INTERACT is truly international in its spirit and has attracted researchers from several countries and cultures. With an emphasis on inclusiveness, it works to lower the barriers that prevent people in developing countries from participating in conferences. As a multidisciplinary field, HCI requires interaction and discussion among diverse people with different interests and backgrounds. The 17th IFIP TC13 International Conference on Human-Computer Interaction (INTERACT 2019) took place during 2-6 September 2019 in Paphos, Cyprus. The conference was held at the Coral Beach Hotel Resort, and was co-sponsored by the Cyprus University of Technology and Tallinn University, in cooperation with ACM and ACM SIGCHI. This volume contains the Adjunct Proceedings to the 17th INTERACT Conference, comprising a series of selected papers from workshops, the Student Design Consortium and the Doctoral Consortium. The volume follows the INTERACT conference tradition of submitting adjunct papers after the main publication deadline, to be published by a University Press with a connection to the conference itself. In this case, both the Adjunct Proceedings Chair of the conference, Dr Usashi Chatterjee, and the lead Editor of this volume, Dr Fernando Loizides, work at Cardiff University which is the home of Cardiff University Press
