    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    TOWARDS AN UNDERSTANDING OF EFFORTFUL FUNDRAISING EXPERIENCES: USING INTERPRETATIVE PHENOMENOLOGICAL ANALYSIS IN FUNDRAISING RESEARCH

    Physical-activity oriented community fundraising has experienced an exponential growth in popularity over the past 15 years. The aim of this study was to explore the value of effortful fundraising experiences, from the point of view of participants, and explore the impact that these experiences have on people’s lives. This study used an IPA approach to interview 23 individuals, recognising the role of participants as proxy (nonprofessional) fundraisers for charitable organisations, and the unique organisation donor dynamic that this creates. It also bought together relevant psychological theory related to physical activity fundraising experiences (through a narrative literature review) and used primary interview data to substantiate these. Effortful fundraising experiences are examined in detail to understand their significance to participants, and how such experiences influence their connection with a charity or cause. This was done with an idiographic focus at first, before examining convergences and divergences across the sample. This study found that effortful fundraising experiences can have a profound positive impact upon community fundraisers in both the short and the long term. Additionally, it found that these experiences can be opportunities for charitable organisations to create lasting meaningful relationships with participants, and foster mutually beneficial lifetime relationships with them. Further research is needed to test specific psychological theory in this context, including self-esteem theory, self determination theory, and the martyrdom effect (among others)

    Examining the Impact of Personal Social Media Use at Work on Workplace Outcomes

    A noticable shift is underway in today’s multi-generational workforce. As younger employees propel digital workforce transformation and embrace technology adoption in the workplace, organisations need to show they are forward-thinking in their digital transformation strategies, and the emergent integration of social media in organisations is reshaping internal communication strategies, in a bid to improve corporate reputations and foster employee engagement. However, the impact of personal social media use on psychological and behavioural workplace outcomes is still debatebale with contrasting results in the literature identifying both positive and negative effects on workplace outcomes among organisational employees. This study seeks to examine this debate through the lens of social capital theory and study personal social media use at work using distinct variables of social use, cognitive use, and hedonic use. A quantitative analysis of data from 419 organisational employees in Jordan using SEM-PLS reveals that personal social media use at work is a double-edged sword as its impact differs by usage types. First, the social use of personal social media at work reduces job burnout, turnover intention, presenteeism, and absenteeism; it also increases job involvement and organisational citizen behaviour. Second, the cognitive use of personal social media at work increases job involvement, organisational citizen behaviour, employee adaptability, and decreases presenteeism and absenteeism; it also increases job burnout and turnover intention. Finally, the hedonic use of personal social media at work carries only negative effects by increasing job burnout and turnover intention. This study contributes to managerial understanding by showing the impact of different types of personal social media usage and recommends that organisations not limit employee access to personal social media within work time, but rather focus on raising awareness of the negative effects of excessive usage on employee well-being and encourage low to moderate use of personal social media at work and other personal and work-related online interaction associated with positive workplace outcomes. It also clarifies the need for further research in regions such as the Middle East with distinct cultural and socio-economic contexts

    Stakeholder Governance: Empirical and Theoretical Developments

    Get PDF
    Stakeholder governance receives attention across many disciplines, resulting in fragmented knowledge. The inherent complexity of stakeholder governance requires the integration of this knowledge to develop comprehensive and inclusive theories to better conceptualize this phenomenon. In this research, we develop stakeholder governance through empirical and theoretical approaches. In the first essay, we use multiple case comparisons to empirically examine how and why organizations manage food waste to develop grounded theory through contextualized explanations. We contribute grounded theoretical and empirical evidence to show that food waste represents a significant business problem. Our data suggests that dimensions of logistics and stakeholder governance dictate how and why organizations manage food waste. These findings stimulate a deeper dive into stakeholder governance, revealing fragmentations in knowledge that require holistic, interdisciplinary review and synthesis. In the second essay, we identify definitions and terminologies, review the evolution of theories and orientations, organize mechanisms and conceptualizations, synthesize key theoretical tensions, and offer suggestions for future research to contribute theoretical developments for stakeholder governance. We contribute pluralist conceptual frameworks that integrate knowledge across disciplines to provide a comprehensive overview and recommendations. Overall, we contribute empirical and theoretical research to advance theory development for stakeholder governance

    Graphical scaffolding for the learning of data wrangling APIs

    In order for students across the sciences to avail themselves of modern data streams, they must first know how to wrangle data: how to reshape ill-organised, tabular data into another format, and how to do this programmatically, in languages such as Python and R. Despite the cross-departmental demand and the ubiquity of data wrangling in analytical workflows, the research on how to optimise the instruction of it has been minimal. Although data wrangling as a programming domain presents distinctive challenges - characterised by on-the-fly syntax lookup and code example integration - it also presents opportunities. One such opportunity is how tabular data structures are easily visualised. To leverage the inherent visualisability of data wrangling, this dissertation evaluates three types of graphics that could be employed as scaffolding for novices: subgoal graphics, thumbnail graphics, and parameter graphics. Using a specially built e-learning platform, this dissertation documents a multi-institutional, randomised, and controlled experiment that investigates the pedagogical effects of these. Our results indicate that the graphics are well-received, that subgoal graphics boost the completion rate, and that thumbnail graphics improve navigability within a command menu. We also obtained several non-significant results, and indications that parameter graphics are counter-productive. We will discuss these findings in the context of general scaffolding dilemmas, and how they fit into a wider research programme on data wrangling instruction

    Groundwater : Making the Invisible Visible : FCDO Briefing Pack on Water Governance, Finance and Climate Change

    Get PDF
    Did you know that more people use groundwater for drinking than use rainwater or surface water and that agriculture is responsible for 70% of global water withdrawal? Groundwater is water found underground in aquifers which, although hidden from view, are vital to agriculture, economic growth, nature and health. Groundwater is an especially important source of water as rainfall varies due to Climate Change - see the latest IPCC report for more details. This briefing pack provides some of the latest evidence and information about groundwater. It also presents information on how the Climate and Environment Department at FCDO is tackling water security to reach two overarching goals: > Tackle and reverse growing water insecurity and its consequences caused by depletion and degradation of natural water sources > Address poor water management and increasing demand In this pack we discuss the UK’s Water action at COP26; programme activities around water and climate, water governance, finance, and gender and the UK’s welldeveloped water ‘offer’, that together, can help reach the goal of global water security. Here you will find key facts, messages and videos,– all intended for colleagues invited to World Water Day events or wanting to engage in some water diplomacy!

    "Alien and Critical": The Modernist Satiric Practices of Djuna Barnes, Wyndham Lewis, and Virginia Woolf

    Get PDF
    This dissertation offers an extended analysis of the modernist satiric practices of authors Djuna Barnes, Wyndham Lewis, and Virginia Woolf in a selection of works spanning different genres published between 1913 and 1954. With these authors works as evidence, I suggest that satire undergoes a significant shift in the first half of the twentieth century as it departs from its premodern roots as a fixed genre or mode, instead becoming a diffuse element that intermittently shapes formal aspects and produces complex critiques. This shift partly results from new formulations of genderfrom altered understandings of masculinity and femininity to the emergence of what we now refer to as queer, nonbinary, and trans identitiesand the way in which what I call the instrumentality of satire enables a range of satiric attacks across different subject positions and a volatile political spectrum. Through a highly comparative approach, I draw upon formalist, feminist, and sociological theories to trace the different networks in which the texts of focus and their authors are embedded (networks of readers, artistic movements, political transformations, marketplaces, and discourses of gender and sexuality) to understand more thoroughly the satire that emerges from these texts. Each chapter pairs discrete investigations of works by each individual author, guided by an overarching topic (Chapter 1 explores networks of satire, Chapter 2 examines satiric method and the novel, and Chapter 3 considers satiric forms of life writing), and ends with a shorter section that compares the three authors works within a specific thematic framework (Chapter 1 with respect to the notion of authority, Chapter 2 through party scenes, and Chapter 3 concerning the portrait genre). My research reveals that the modernist satiric exchanges within these networks can be analyzed as, on the one hand, manifestations of the selected periods political dynamics and, on the other hand, cultural productions that altered how gender was discursively constructed within specific social environments of that period. In brief, the study illustrates how gender and its performance, aesthetics, and rhetoric become central to the production and function of satire in modernist art and literature

    Livestock-associated Methicillin-resistant Staphylococcus aureus (MRSA) are an emerging public-health issue in Australia, particularly amongst livestock and animal workers. We examined MRSA, isolated from humans and animals in Australia whole-genome sequencing and identified zoonotic and anthropozoonotic MRSA transmission, and antimicrobial-resistance gene transfer between MRSA of different host origin. This work highlights the need for expanded monitoring of microbial livestock pathogens and indicates the importance of prudent antimicrobial use in animal health
